How to Write an Evidence-Based Practice Paper in Nursing

How to Write Evidence-Based Papers in Nursing

Some call it an EBP paper while some evidence-based research paper, and it comes in many other forms as well, including EBP case reports, EBP capstone projects, EBP coursework, or EBP thesis. Regardless of the name, without explicit knowledge on how to write an evidence-based practice paper, you cannot wrap your mind around it. Evidence-based papers are written by students so that they can develop confidence, research interests, critical thinking, creativity, and decision-making skills that are applicable in real-world clinical settings.

Any nursing school student must write an evidence-based practice paper. In most cases, EBP papers can come in the form of change management papers where quality improvement processes are recommended. To avoid making blunders when writing, it is vital to grasp the entire writing process.

Unlike other nursing papers and essays, evidence-based practice papers require in-depth reasoning, research, and reading. We acknowledge that writing a great evidence-based paper that is gradable takes sweat and is very challenging.

We have compiled this guideline for writing an evidence-based nursing paper to ease the burden on your side. If you quite can't find it easy even after reading this article, we have experienced nursing paper writers who can always help you.

We are the best nursing paper writing service; we do this to help you take care of your wellbeing, achieve freedom, and extend your time caring for others in your clinical. Let us dig right into it, won't we?

What is Evidence-Based Practice?

Evidence-Based Practice in the field of nursing focuses on the premise that medical practice should focus on adapted and developed principles through a cycle of evidence, research, and analysis of theory. Evidence-based practice intends to address the changes in practice based on the nursing and non-nursing theories developed through proper research.

In nursing, the implementation of EBP comes in the form of a systematic review, where research is reviewed based on a particular guideline to determine its suitability for being used as a gold standard in practice.

The systematic review helps in sense-making from the mammoth of information available for effective change management, implementation, and institutionalization. 

The EBP process involves six significant steps:

  • Assessment of the need for change : This entails the formulation of a research question or hypothesis based on the gaps in current practice.
  • Location of the best evidence : Depending on the levels of nursing resources or evidence, the next step entails assessing the credibility, reliability, and relevance of the evidence or peer-reviewed articles.
  • Synthesis of evidence : This step involves the comparison and contrast of available sources of evidence to establish similarities and differences to determine the best course of approach.
  • Designing change : through the results of the synthesis of the available evidence, the next step is to create an effective change based on the evidence collected. It also involves drafting the change implementation plan within the clinical setting.
  • Implementing and Evaluating Change : After the design comes to the process of initiating the change through change advocates such as nurse leaders and nurses themselves, it is the phase where the new process is established into practice. Various change management theories can be followed to ensure the fruition of the change management plan.
  • Integration and Sustaining Change : Once the new evidence has been used to implement change, it is adopted through policy or guidelines within the clinical settings. It also entails the process of continuous improvement to achieve the best.

Steps of Writing an EBP Research Paper in Nursing

Once you have been assigned to write an evidence-based paper, you need to follow the steps below to write the best essay.

1. Choose a Topic for your Paper

There are many methods you can use when choosing an EBP topic. You can get ideas from your coursework, peer-reviewed sources, class assignments, and past evidence-based projects done. Thanks to the Internet, there are various evidence-based practice topic ideas. However, choose a topic that resonates well with your passion and interest in nursing practice. For instance, if you are looking forward to improving patient flow in the ED using technology, be sure that you are cognizant of such technology as EHR or HIT. Begin by exploring the assignment and make some notes; you should then settle for a tentative topic.

2. Consult with your Professor/Instructor

Nursing education, just like nursing practice, calls for collaboration and getting feedback. Therefore, once you have selected a creative, evidence-based practice topic , you must make an appointment with either the writing center or the professor/instructor for confirmation. In some instances, your professor/instructor will request for an evidence-based practice proposal. In the EBP proposal, you must state the nursing issue you intend to solve, the change management process, and the rationale for the change. If it is convincing enough, you will get a go-ahead. Otherwise, you will need to revise the EBP nursing proposal.

Tip: SELECT a good health indicator (disease, health conditions, working/living conditions) , DESCRIBE the population or sub-population of the target, find EVIDENCE of around 7-10 peer-reviewed sources that support your proposal, and DESCRIBE the intended outcomes and rationale of the change proposed in the clinical setting.

Some of the health indicators you can use for your EBP paper include socio-economic status; gender, education, environment, employment, genetic endowment, culture, child development, healthcare services, access, quality, cost of care, social support, coping skills, etc.

The EBP papers can include a change model, population health model, nursing theory, and nursing interventions and each must be justified using credible evidence.

3. Gathering Supporting Evidence - Research

The backbone of an evidence-based paper is evidence. Therefore, you need to extensively research both online and print sources to get facts to support your EBP paper thesis statement. Once you have developed the problem statement and outlined the thesis statement, you should critically evaluate the sources to determine those that support the thesis.

In some instances, the instructor might request you to write an annotated bibliography or critically analyze each of the articles or the main article that supports your evidence-based practice paper. A common approach is through using an evidence evaluation table. When selecting the sources, remember that there are both primary and secondary sources.

You can get primary and secondary sources from databases such as PubMed, EBSCO, UpToDate, TRIP Database, OVID, The Cochrane Collaboration, and CINAHL.  Besides, you can depend on .gov, .org, and .edu websites to get information. Professional and government organizations, as well as NGOs, can be a starting point of research. They are an excellent resource for statistics, epidemiology data, and further information. Excellent research means that the research question, hypothesis, and thesis statement will be supported and answered.

Deciding on the Best Resources for EBP Papers

There are primary and secondary data sources when it comes to scientific writing. Instead of collecting and analyzing real data as students do for qualitative and quantitative or mixed methods thesis, dissertation, and research papers, an EBP paper is purely based on the published findings from primary research. It is imperative, therefore, that a nursing student only uses credible, valid, and reliable sources. Here are three criteria to select a good source for your EBP paper:

  • A research journal article is only reliable if published in a reliable database/journal and is peer-reviewed. It depends on the level of the evidence as well. Will the same test yield similar results if replicated?
  • A valid research study has followed the strict research protocols, is up to date, and is relevant to the chosen EBP paper topic selected. Does the study measure what it says it intends to measure?
  • Credible research that can be incorporated into an EBP paper must have verifiable findings, published in a reputable journal, and is scholarly. Is the research study from a reputable journal?
  • Is the research report, article, or journal primary research such as qualitative research, quantitative research, randomized controlled trial, controlled case studies, or quasi-experimental study?

It is only natural that you can dislike the entire process of writing an EBP paper, not because you don't know how to, but probably because of the strict and laborious process. If this is the case, our nursing writing service is all you need for your peace of mind. We have experienced nursing assignment help experts who can craft the best papers for you.

Outline of an Evidence-Based Practice Paper

A good evidence-based paper in nursing must have several parts, each of which are completed with precision, care, and wit. If you have researched online for evidence-based practice paper examples , you will agree with us that the format or structure is more or less as broken down below. It is the same structure you will see on an evidence-based practice paper template that you will likely receive from class.  Here is a critical breakdown of what to include in your nursing evidence-based practice paper:

1. Title of the EBP Paper

A good title will either attract and keep or turn off your audience, instructor/professor. Therefore, having an excellent title for your evidence-based practice case study, report, write-up, or research paper is paramount. The title aims to set the scope of the EBP paper and provide a hint about the hypothesis or thesis statement. It is, therefore, imperative that it is concise, clear, and fine-tuned. If you decide to write the title as a question, you could paraphrase the PICOT statement, for example. Otherwise, it can also take forms such as statements or facts opposing the status quo. Whichever direction you choose to align to, the aim remains constant to give more insight to the reader from the onset.

2. Thesis Statement

While the PICOT statement can already tell what your entire EBP paper is all about, you need to develop a great thesis statement. A thesis statement, usually the last sentence or two, is like a blueprint of the entire paper. It is the foundation upon which the whole paper is built. Take note that a thesis is not a hypothesis, which is an idea that you either want to prove or refute based on a set of available evidence. An evidence-based practice paper with a thesis ultimately earns the best grade without leaving the reader to look for it the entire paper.

The thesis statement must be specific, manageable, and enjoyable. A sample EBP thesis statement can be: According to new developments in genomics and biotechnology, stem cells have reportedly been used in breast cancer treatment with higher chances of remission in the patients. Novel approaches to pain management dictate that a nurse must obtain three kinds of knowledge to respond effectively to patients' pain: knowledge of self, knowledge of standards of care, and knowledge of pain.

A thesis can also be an implied argument, which makes it descriptive. However, not so many professors like such. This paper discusses

3. Introduction

The introduction of evidence-based practice must reflect certain elements. First, you must present a background to the research question or nursing issue. It would help if you also painted a clear picture of the problem through a thorough and brief problem statement and at the same time, provide the rationale. You can organize your intro into a PICO:

Patient/Problem : What problems does the patient group have? What needs to be solved?

Intervention : What intervention is being considered or evaluated? Cite appropriate literature.

Comparison : What other interventions are possible? Cite appropriate literature.

Outcome : What is the intended outcome of the research question?

The thesis statement we have discussed above then comes in as either a sentence or two in the last part of the introduction. The research problem should help generate the research question or hypothesis for the entire EBP paper.

4. Methodology

As indicated before, an EBP research paper does not focus on research; instead, it focuses on a body of knowledge or evidence. For that matter, when writing an EBP paper, you only collect data from literature produced on your chosen topic. A confusing bit when researching evidence to use is deciding on what level of evidence to use. There are systematic reviews, literature reviews, white papers, opinion papers, practice papers, peer-reviewed journals, critically appraised topics, RCTs, Case-controlled studies, or cohort studies, you name it. You must decide which level of evidence is appropriate. It trickles down to the scholarly source's validity, reliability, and credibility. Your methodology should include:

  • The databases you searched, the search terms, the total articles yielded per search, the inclusion and selection criteria, the exclusion criteria.
  • You should indicate the inclusion and exclusion criteria for the articles and the number of articles you finally end up with.

You can further choose to use knowledge as evidence based on authority, a priori, theory, and tenacity, as advised by Fawcett and Garity in their book Evaluating research for evidence-based nursing practice.

5. EBP Literature Review

In the literature review section, you aim to explore the associations of the evidence chosen given your topic. It aims at either finding the gap in those studies or using the knowledge to build on the topic. For instance, if you are to come up with a new management approach for pressure ulcers in palliative care, choose credible evidence on the topic. Find the effectiveness of your proposed approach in other environments, what works well, and what precautions should be taken. It is more of comparing and contrasting the sources. You also ought to be critical as it is the only way you can develop the best EBP paper. It is here that you report your findings from the literature. You can do it in the form of a table outlining the aspects of each study including demographics, samples, methodology, and level of evidence, results, and limitations.

6. Discussion

Like any other professional research setting, the discussion section often discusses the changed practice, implementation approach, and evaluation strategies. This can be your approach as well in your EBP paper. However, go further to explore how the findings led to a given change in practice, the efficiency after that, and suggest the best strategy for implementing the change in your chosen organization. Make comparisons if necessary.

7. Conclusion

In your conclusion, you should wind up the paper, summarize the EBP paper, and leave the readers satisfied. Your revamped thesis statement can feature in the conclusion. Make your conclusion count.

Finally, your EBP paper must have references, works cited, or a bibliography section. You realize that most EBP papers are written in either APA formatting or Harvard formatting .

Furthermore, it would be best if you wrote your abstract section last, which is about 150-250 words. It aims to offer a highlight of the entire evidence-based paper.

Here is a graphic/visual representation of the entire EBP writing process for students.

Evidence-Based Practice (or Evidence-Based Medicine) is, "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research."  (Sackett et al., 1996)

EBP Model

"Evidence-Based Practice (EBP) isn’t about developing new knowledge or validating existing knowledge. It’s about translating the evidence and applying it to clinical decision-making. The purpose of EBP is to use the best evidence available to make patient-care decisions. Most of the best evidence stems from research. But EBP goes beyond research use and includes clinical expertise as well as patient preferences and values. The use of EBP takes into consideration that sometimes the best evidence is that of opinion leaders and experts, even though no definitive knowledge from research results exists."  (Conner, 2014)

The Evidence-Based Practice process has five steps. The process begins with the patient's situation and proceeds to asking an answerable question, finding and getting the evidence, evaluating the evidence and then applying the information to the patient's situation. Lastly, perform a reflective review of the process and consider areas for improvement.

About This Guide

Photograph of a doctor explaining results to a patient from a laptop.

The purpose of this guide is to define the subject of Evidence-Based Practice and to inform students, faculty, and our community of the many types of resources available to explore this topic.

While the concepts of evidence-based practice (EBP) are now commonly embraced in fields such as education, law and management, much of it emerged in medicine. Accordingly, most of the examples and resources suggested in this guide are based on clinical research.

Use the tabs to learn more about the five-step Evidence-Based Practice cycle and navigate to further reading.

"Evidence based practice (EBP) is the integration of clinical expertise, patient values, and the best evidence into the decision making process for patient care."

Sackett, D.L., et al. (2000). Evidence-based medicine: How to practice and teach EBM (2nd ed.). Edinburgh: Churchill Livingstone.

In contrast with a reliance on history or traditional solutions, EBP is the combination of existing clinical knowledge, consideration of the patient's needs and choices, and the most up-to-date and credible scientific research available. In an evidence-based approach, the clinician will begin by forming answerable questions about diagnosis, treatment, harm / etiology, prognosis or prevention with the patient's specific needs factored in. A research path is then chosen depending on the question type. The clinician (and often, a medical librarian) will gather information from the appropriate types of studies based on the strength and precision of their research methodology (more on the next page). The research is appraised for quality and relevance and then implemented based on each unique scenario. EBP also includes evaluation of the efficacy of the implemented clinical decision.

A Venn diagram with three circles. Best Research Evidence, Clinical Expertise, Patient Values. EBP is where these circles intersect.

Adoption of evidence-based practices can be found across many disciplines in the sciences, medicine and academia. Here are just a few of the statements you'll find among professional associations:

  • The National Council of State Boards of Nursing's Evidence-based Regulation of Nursing Education page and position statement .
  • The American Speech-Language-Hearing Association's Evidence-Based Practice in Communication Disorders [Position Statement]
  • The American Psychological Association's Policy Statement on Evidence-Based Practice in Psychology

The EBP Cycle

There are 5 steps in the EBP cycle:

Construct an answerable clinical question derived from the patient dilemma

Systematically retrieve the best available research

Critically appraise the validity and applicability of the evidence

Integrate evidence with clinical expertise and patient preferences and apply to practice

Evaluate the performance and success of the change in practice. Ask new questions...

This guide focuses on the first three steps in the cycle: developing a searchable question, finding the evidence and appraising the quality of the evidence.

Supporting your practice: Evidence-Based Medicine.  By Dr Mary Bushell MPS . 6   Read this article and you should be able to:

  • Define Evidence-Based Medicine (EBM)
  • Explain different study designs and the level of evidence they generate
  • Explain the significance of probability (p) values, confidence intervals (CI), relative risk (RR), odds ratios (OR), hazard ratios (HR), and number-needed-to-treat (NNT)
  • Discuss the importance of EBM for healthcare professionals.

This guide includes a tutorial about Evidence-Based Practice (EBP) in Health, a Reference Shelf of supporting eBooks, and a Toolkit of online sources of evidence.

evidence based practice essay introduction

The goals of the tutorial are to clearly outline the theory of EBP and to explain how that theory can be put to practice in the day-to-day work of caring for patients.   The tutorial includes an introduction and modules that follow the "5A's Cycle" of EBP that include assessing the patient and prioritizing questions about his/her care, asking a focused clinical question, acquiring the evidence to answer the question, appraising the research, applying the research findings to patient care, and finally auditing your performance.. The cycle begins again with an assessment of the patient and the patient's care. 1

The tutorial focuses largely on efficient literature searching and therefore on asking questions and acquiring the best evidence.  In particular, it suggests specific strategies for finding evidence from primary studies, systematic reviews and meta-analyses using EBP tools.  Appraisal is also touched upon, with suggestions for scanning search results to identify articles more likely to yield robust, applicable evidence.

At the end of the tutorial, you should be able to:

  • Formulate a clinical question using the PICO framework;
  • Identify five common categories of clinical questions;
  • Identify which research methodologies provide the best evidence for your question type;
  • Distinguish between systematic reviews, meta-analyses and narrative or clinical topic reviews;
  • Search Medline/PubMed effectively for studies likely to provide the current best evidence by
  • Identifying appropriate search terms, including Medical Subject Headings (MeSH) terms; and
  • Employ evidence filters such as PubMed's Clinical Queries;
  • Identify articles from your PubMed search results that are most likely to provide current, valid, reliable and relevant evidence to answer your question.

This tutorial assumes you already have some familiarity with basic and advanced PubMed search techniques, as well as with MeSH searching.

There are many excellent on-line and print guides that address the critical appraisal of a research report and the application of evidence to an individual patient's care. You will find links to selected resources that provide especially rich content in these areas in the Appraise and Apply modules of this tutorial.

It is best to work systematically through the various modules, starting with Introduction: About Evidence-Based Practice, and then the five modules.

Reference Shelf of EBP eBooks and Books

The Library has a vast range of books and ebooks about EBP that can be found via Library Search  (the Library Catalogue).  The Reference Shelf in this guide lists a range of the EBP eBooks and Books by category and discipline area.

What is Evidence-Based Practice?

The classic definition of Evidence-Based Practice (EBP) is from Dr David Sackett. EBP is “the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research”. 2

EBP has developed over time to now integrate the best research evidence, clinical expertise, the patient's individual values and circumstances, and the characteristics of the practice in which the health professional works. 3

So, EBP is not only about applying the best research evidence to your decision-making, but also using the experience, skills and training that you have as a health professional and taking into account the patient's situation and values (e.g. social support, financial situation), as well as the practice context (e.g. limited funding) in which you are working.  The process of integrating all of this information is known as clinical reasoning.  When you consider all of these four elements in a way that allows you to make decisions about the care of a patient, you are engaging in EBP. 4

Why is Evidence-Based Practice Important?

EBP is important because it aims to provide the most effective care that is available, with the aim of improving patient outcomes.  Patients expect to receive the most effective care based on the best available evidence.  EBP promotes an attitude of inquiry in health professionals and starts us thinking about: Why am I doing this in this way?  Is there evidence that can guide me to do this in a more effective way?  As health professionals, part of providing a professional service is ensuring that our practice is informed by the best available evidence.  EBP also plays a role in ensuring that finite health resources are used wisely and that relevant evidence is considered when decisions are made about funding health services. 4

What happened before Evidence-Based Practice?

Before EBP health professionals relied on the advice of more experienced colleagues, often taken at face value, their intuition, and on what they were taught as students.  Experience is subject to flaws of bias and what we learn as students can quickly become outdated.  Relying on older, more knowledgeable colleagues as a sole information source can provide dated, biased and incorrect information.  This is not to say that clinical experience is not important - it is in fact part of the definition of EBP.  However, rather than relying on clinical experience alone for decision making, health professionals need to use clinical experience together with other types of evidence-based information. 5

Is not all Published Research of Good Quality?

Not all research is of sufficient quality to inform clinical decision making.  Therefore you need to critically appraise evidence before using it to inform your clinical decision making. The three major aspects of evidence that you need to critically appraise are:

  • Validity - can you trust it?
  • Impact - are the results clinically important?

Evidence-based practice (EBP) prevents unsafe/inefficient practices and improves healthcare quality, but its implementation is challenging due to research and practice gaps. A focused educational program can assist future nurses to minimize these gaps. This study aims to assess the effectiveness of an EBP educational program on undergraduate nursing students’ EBP knowledge and skills. A cluster randomized controlled trial was undertaken. Six optional courses in the Bachelor of Nursing final year were randomly assigned to the experimental (EBP educational program) or control group. Nursing students’ EBP knowledge and skills were measured at baseline and post-intervention. A qualitative analysis of 18 students’ final written work was also performed. Results show a statistically significant interaction between the intervention and time on EBP knowledge and skills ( p = 0.002). From pre- to post-intervention, students’ knowledge and skills on EBP improved in both groups (intervention group: p < 0.001; control group: p < 0.001). At the post-intervention, there was a statistically significant difference in EBP knowledge and skills between intervention and control groups ( p = 0.011). Students in the intervention group presented monographs with clearer review questions, inclusion/exclusion criteria, and methodology compared to students in the control group. The EBP educational program showed a potential to promote the EBP knowledge and skills of future nurses.

1. Introduction

Evidence-based practice (EBP) is defined as “clinical decision-making that considers the best available evidence; the context in which the care is delivered; client preference; and the professional judgment of the health professional” [ 1 ] (p. 2). EBP implementation is recommended in clinical settings [ 2 , 3 , 4 , 5 ] as it has been attributed to promoting high-value health care, improving the patient experience and health outcomes, as well as reducing health care costs [ 6 ]. Nevertheless, EBP is not the standard of care globally [ 7 , 8 , 9 ], and some studies acknowledge education as an approach to promote EBP adoption, implementation, and sustainment [ 10 , 11 , 12 , 13 , 14 , 15 ].

It has been recommended that educational curricula for health students should be based on the five steps of EBP in order to support developing knowledge, skills, and positive attitudes toward EBP [ 16 ]. These steps are: translation of uncertainty into an answerable question; search for and retrieval of evidence; critical appraisal of evidence for validity and clinical importance; application of appraised evidence to practice; and evaluation of performance [ 16 ].

To respond to this recommendation, undergraduate nursing curricula should include courses, teaching strategies, and training that focus on the development of research and EBP skills for nurses to be able to incorporate valid and relevant research findings in practice. Nevertheless, teaching research and EBP to undergraduate nursing students is a challenging task. Some studies report that undergraduate students have negative attitudes/beliefs toward research and EBP, especially toward the statistical components of the research courses and the complex terminology used. Additionally, students may not understand the importance of the link between research and clinical practice [ 17 , 18 , 19 ]. In fact, a lack of EBP and research knowledge is commonly reported by nurses and nursing students as a barrier to EBP. It is imperative to provide the future nurses with research and EBP skills in order to overcome the barriers to EBP use in clinical settings.

At an international level, several studies have been performed with undergraduate nursing students to assess the effectiveness of EBP interventions on multiple outcomes, such as EBP knowledge and skills [ 20 , 21 , 22 , 23 ]. The Classification Rubric for EBP Assessment Tools in Education (CREATE) [ 24 ] suggests EBP knowledge should be assessed cognitively using paper and pencil tests, as EBP knowledge is defined as “learners’ retention of facts and concepts about EBP” [ 24 ] (p. 5). Additionally, the CREATE framework suggests EBP skills should be assessed using performance tests, as skills are defined as “the application of knowledge” [ 24 ] (p. 5). Despite these recommendations, few studies have assessed EBP knowledge and skills using both cognitive and performance instruments.

Therefore, this study aims to evaluate the effectiveness of an EBP educational program on undergraduate nursing students’ EBP knowledge and skills using a specific cognitive and performance instrument. The intervention used in this study was recently developed [ 25 ], and this is the first study designed to assess its effectiveness in undergraduate EBP.

2. Materials and Methods

2.1. design.

A cluster randomized controlled trial with two-armed parallel group design was undertaken (ClinicalTrials.gov Identifier: {"type":"clinical-trial","attrs":{"text":"NCT03411668","term_id":"NCT03411668"}} NCT03411668 ).

2.2. Sample Size Calculation

The sample size was calculated using the software G*Power 3.1.9.2. (Heinrich-Heine-Universität Dusseldorf, Düsseldorf, Germany) Recognizing that there were no studies performed a priori using a cognitive and performance instrument to assess the effectiveness of an EBP educational program on undergraduate nursing students’ EBP knowledge and skills, we used an effect size of 0.25, which is a small effect size as proposed by Cohen [ 26 ]. A power analysis based on a type I error of 0.05; power of 0.80; effect size f = 0.25; and ANOVA repeated measures between factors determined a sample size of 98 as total.

Taking into account that our study used clusters (optional courses) and that each one had an average of 25 students, we needed at least four clusters to cover the total sample size of 98. However, to cover potential losses to follow-up, we included a total of six optional courses.

2.3. Participants’ Recruitment and Randomization

We recruited participants from one Portuguese nursing school in 2018. From the 12 optional clinical nursing courses (such as Community Nursing Intervention in Vulnerable Groups; Ageing; Health and Citizenship; The Child with Special Needs: Diagnoses and Interventions in Pediatric Nursing; Liaison Psychiatry Nursing; Nursing in the Emergency Room; etc.) in the 8th semester of the nursing program (last year before graduation), students from three clinical nursing courses were randomly assigned to the experimental group (EBP educational program) and students from another three clinical nursing courses were randomly assigned to the control group (no intervention— education as usual ) before the baseline assessment. An independent researcher performed this assignment using a random number generator from the random.org website [ 27 ]. This assignment was performed based on a list of the 12 optional courses provided through the nursing school’s website.

2.4. Intervention Condition

The participants in the intervention group received education as usual plus the EBP educational program, which was developed by Cardoso, Rodrigues, and Apóstolo [ 25 ]. This intervention included EBP contents regarding models of thinking about EBP, systematic reviews types, review question development, searching for studies, study selection process, data extraction, and data synthesis.

This program was implemented in 6 sessions over 17 weeks:

  • Sessions 1–3—total of 12 h (4 h per session) during the first 7 weeks using expository methods with practice tasks to groups of 20–30 students.
  • Sessions 4–6—total of 6 h (2 h per session) during the last 10 weeks using active methods through mentoring to groups of 2–3 students.

Due to the nature of the intervention, it was not possible to blind participants regarding treatment assignment nor was it feasible to blind the individuals delivering treatment.

2.5. Control Condition

The participants in the control group received only education as usual; i.e., students allocated to this control condition received the standard educational contents (theoretical, theoretical–practical, practical) delivered by the nursing educators of the selected nursing school.

2.6. Assessment

All participants were assessed before (week 0) and after the intervention (week 18) using a self-report instrument. EBP knowledge and skills were assessed by the Adapted Fresno Test for undergraduate nursing students [ 28 ]. This instrument was adapted from the Fresno Test, which was originally developed in 2003 to measure knowledge and skills on EBP in family practice residents [ 29 ]. The Adapted Fresno Test for undergraduate nursing students has seven short answer questions and two fill-in-the-blank questions [ 28 ]. At the beginning of the instrument, two scenarios, which suggest clinical uncertainty, are presented. These two scenarios are used to guide the answers to questions 1 to 4: (1) write a clinical question; (2) identify and discuss the strengths and weaknesses of information sources as well as the advantages and disadvantages of information sources; (3) identify the type of study most suitable for answering the question of one of the clinical scenarios and justify the choice; and (4) describe a possible search strategy in Medline for one of the clinical scenarios, explaining the rationale. The next three short answer questions require that the students identify topics for determining the relevance and validity of a research study and address the magnitude and value of research findings. The last two questions are fill-in-the-blank questions. The answers are scored using a modified standardized grading system [ 28 ], which was adapted from the original [ 29 ]. The instrument has a total minimum score of 0 and a maximum score of 101. The inter-rater correlation for the total score of the Adapted Fresno Test was 0.826 [ 28 ]. The rater that graded the answers to the Adapted Fresno Test was blinded to treatment assignment.

Despite the fact that in the study proposal we did not consider any kind of qualitative analysis in order to assess EBP knowledge and skills in a more practical context, we decided during the development of the study to perform a qualitative analysis of monographs at the posttest. The monographs were developed by small groups of nursing students and were the final written work submitted by the students for their bachelor’s degree course. In this work, the students were asked to define a review question regarding the context of clinical practice where they were performing their clinical training. Students then proceeded to answer the review question through a systematic process of searching and selecting relevant studies and extracting and synthesizing the data. From the 58 submitted monographs (30 from the control group and 28 from the intervention group), 18 were randomized for evaluation (nine from the control group and nine from the intervention group) by an independent researcher using the random.org website [ 27 ] based on a list provided by the research team. Three independent experts (one psychologist with a doctoral qualification and two qualified nurses, one with a master’s degree) performed a qualitative analysis of the selected monographs. All experts had experience with the EBP approach and were blinded to treatment assignment. The experts independently used an evaluation form to guide the qualitative analysis of each monograph. This form presented 11 guiding criteria regarding review questions, inclusion/exclusion criteria, methodology (namely search strategy, study selection process, data extraction, and data synthesis), results presentation, and congruency between the review questions and the answers to them that were provided in the conclusion section. Thereafter, the experts met to discuss any discrepancies in their qualitative analysis until consensus was reached.

2.7. Statistical Analyses

The data were analyzed using Statistical Package for the Social Sciences (SPSS; version 24.0; SPSS Inc., Chicago, IL, USA). Differences in sociodemographic characteristics of study participants and outcome data at baseline were analyzed using Pearson’s chi-squared test for nominal data and independent the t -test for continuous data.

Taking into account the central limit theorem and that ANOVA tests are robust to violation of assumptions [ 30 ], we decided to perform two-way mixed ANOVA to compare the outcome between and within groups. The Wilcoxon signed-rank test was used to analyze how many participants had improved their EBP knowledge and skills item-by-item, how many remained the same, and how many had decreased performance within each group. Statistical significance was determined by p -values less than 0.05.

To minimize the noncompliance impact, an intention-to-treat (ITT) analysis was used to analyze participants in the groups that they were initially randomized to [ 31 ] by using the last observation carried forward imputation method.

2.8. Ethics

This study was approved by the Ethical Committee of the Faculty of Medicine of the University of Coimbra (Reference: CE-037/2017). The institution where the study was carried out provided written approval. All participants gave informed consent, and the data were managed in a confidential way.

Twelve potential clusters (optional courses in the 8th semester of the nursing program) were identified as eligible for this study. Of these, three were randomized for the intervention group and three for the control group. During the intervention, eight participants (two in the intervention group and six in the control group) were lost to follow-up because they did not fill-in the instrument in the post-intervention. Figure 1 shows the flow of participants through each stage of the trial.

3.1. Demographic Characteristics

As Table 1 displays, 148 undergraduate nursing students with an average age of 21.95 years (SD = 2.25; range: 21–41) participated in the study. A large majority of the sample were female ( n = 118, 79.7%), had a 12th grade educational level ( n = 144, 97.3%), and had participated in some form of EBP training ( n = 121, 81.8%).

Socio-demographic characterization of the sample—ITT analysis.

* Defined as any kind and duration of evidence-based practice (EBP) training, such as EBP contents in a course, a workshop, a seminar.

At baseline, the experimental and control groups were comparable regarding sex, age, education, EBP training, and performance on the Adapted Fresno Test ( Table 1 and Table 3). The baseline data were similar with dropouts excluded; therefore, only ITT analysis results are presented.

3.2. EBP Knowledge and Skills

3.2.1. adapted fresno test.

The two-way mixed ANOVA showed a statistically significant interaction between the intervention and time on EBP knowledge and skills, F (1, 146) = 9.550, p = 0.002, partial η 2 = 0.061 ( Table 2 ). Excluding the dropouts, the two-way mixed ANOVA analysis was similar. Thus, only the ITT analysis results are presented.

Main effects of time and group and interaction effects on EBP knowledge and skills—ITT analysis.

To determine the difference between groups at baseline and post-intervention, two separate between-subjects ANOVAs (i.e., two separate one-way ANOVAs) were performed. At the pre-intervention, there was no statistically significant difference in EBP knowledge and skills between groups: F (1,146) = 0.221, p = 0.639, partial η 2 = 0.002. At the post-intervention, there was a statistically significant difference in EBP knowledge and skills between groups: F (1,146) = 6.720, p = 0.011, partial η 2 = 0.044 ( Table 3 ).

Repeated measures ANOVA and between-subjects ANOVA—ITT analysis.

To determine the differences within groups from the baseline to post-intervention, two separate within-subjects ANOVAs (repeated measures ANOVAs) were performed. There was a statistically significant effect of time on EBP knowledge and skills for the intervention group: F (1,73) = 53.028, p < 0.001, partial η 2 = 0.421 and for the control group: F (1,73) = 13.832, p < 0.001, partial η 2 = 0.159 ( Table 3 ).

The results of repeated measures ANOVA and between-subjects ANOVA analysis are similar if we exclude the dropouts; therefore, only ITT analysis results are presented.

The results of the Wilcoxon signed-rank test for each item of the Adapted Fresno Test are presented in Table 4 . The results of this analysis revealed that students in both the intervention and control groups significantly improved their knowledge and skills in writing a focused clinical question (Item 1) (intervention group: Z = −4.572, p < 0.000; control group: Z = −2.338, p = 0.019), in building a search strategy (item 3) (intervention group: Z = −4.740, p < 0.000; control group: Z = −4.757, p < 0.000), in identifying and justifying the study design most suitable for answering the question of one of the clinical scenarios (item 4) (intervention group: Z = −4.508, p < 0.000; control group: Z = −3.738, p < 0.000), and in describing the characteristics of a study to determine its relevance (item 5) (intervention group: Z = −2.699, p = 0.007; control group: Z = −1.980, p = 0.048).

Within groups comparison with Wilcoxon signed-rank test for each item of the Adapted Fresno Test—ITT analysis.

The students in the control group significantly improved their knowledge and skills in describing the characteristics of a study to determine its validity (item 6) ( Z = −2.714, p = 0.007). The students in the intervention group significantly improved their knowledge and skills in describing the characteristics of a study to determine its magnitude and significance (item 7) ( Z = −2.543, p = 0.011). No other significant differences were detected.

The results of the within groups comparison with the Wilcoxon signed-rank test are similar if we exclude the dropouts; therefore, only ITT analysis results are presented.

3.2.2. Qualitative Analysis of Monographs

Based on the experts’ consensus report of each monograph, the analysis of the intervention group monographs showed that the students’ groups clearly defined their review questions and inclusion/exclusion criteria. These groups of students effectively searched for studies using appropriate databases, keywords, Boolean operators, and truncation. Additionally, we found thorough descriptions from students concerning the selection process, data extraction, and data synthesis. However, only three students’ groups provided a good description of the review findings with an appropriate data synthesis as well as a clear answer to the review question in the conclusion section of their monographs. It is noted that the criteria for the results and conclusion sections were more difficult to successfully achieve, even in the intervention group.

The monographs of the control groups showed weaknesses throughout. From the nine monographs of the control group, only two presented the review question in a way that was clearly defined. In all of the monographs, the inclusion/exclusion criteria were either not very informative, unclear, or did not match with the defined review questions. Additionally, the search strategies were not clear and demonstrated limited understanding, such as lack of use of appropriate synonyms, absent truncations, and no definition of the search field for each word or expression to be searched. None of the monographs from the control group reported information about the methods used to study the selection process, to extract data, or to synthesize data. In the conclusion section, students from the control group also demonstrated difficulties in synthesizing the data and limitations by providing a clear answer to the review question.

4. Discussion

This study sought to evaluate the effectiveness of an EBP educational program on undergraduate nursing students’ EBP knowledge and skills. Even though both groups improved after the intervention in EBP knowledge and skills, the study results showed that the improvement was greater in the intervention group. This result was reinforced by the results of the qualitative analysis of monographs.

To the best of our knowledge, this is the first study to use a cognitive and performance assessment instrument (Adapted Fresno Test) with undergraduate nursing students, as suggested by CREATE [ 24 ]. Additionally, it is the first study conducted using the EBP education program [ 25 ]. Therefore, comparison of our findings with similar studies in terms of the type of assessment instrument and intervention is limited.

However, comparing our study with other previous research using other types of instruments and interventions demonstrates similar results [ 20 , 21 , 22 , 23 ]. In a quasi-experimental study [ 20 ], it was found that an EBP educational teaching strategy showed positive results in improving EBP knowledge in undergraduate nursing students. A study showed that undergraduate nursing students who received an EBP-focused interactive teaching intervention improved their EBP knowledge [ 21 ]. Another study indicated that a 15-week educational intervention in undergraduate nursing students (second- and third-year) significantly improved their EBP knowledge and skills [ 22 ]. In addition, a study by Zhang, Zeng, Chen, and Li revealed a significant improvement in undergraduate nursing students’ EBP knowledge after participating in a two-phase intervention: a self-directed learning process and a workshop for critical appraisal of literature [ 23 ].

Despite the effectiveness of the program in improving EBP knowledge and skills, the students included in the present study had low levels of EBP knowledge and skills as assessed by the Adapted Fresno Test at the pretest and posttest. These low levels of EBP knowledge and skills, especially at the pretest, might have influenced our study results. As a matter of fact, the Adapted Fresno Test is a demanding test since it requires that students retrieve and apply knowledge while doing a task associated with EBP based on scenarios involving clinical uncertainty. Consequently, this kind of test is very useful to truly assess EBP knowledge retention and abilities in clinical scenarios that do not allow guessing the answers. Notwithstanding, due to these characteristics, the Adapted Fresno Test may possibly be less sensitive when small changes occur or when students have low levels of EBP knowledge and skills. Nevertheless, even using instruments with Likert scales, other studies also showed that students have low levels of EBP knowledge and skills [ 21 , 22 , 23 ].

The low levels of EBP knowledge and skills of the undergraduate nursing students may be a reflection of a persistent, traditional education with regard to research. By this we mean that the focus of training remains on primary research—preparing students to be “research generators” instead of preparing them to be “evidence users” [ 32 ]. Furthermore, the designed and tested intervention used in this study was limited in time (only 17 weeks), was provided by only two instructors, and was delivered to fourth-year undergraduate nursing students, which are limitations for curriculum-wide integration of EBP.

Indeed, a curriculum that promotes EBP should facilitate students’ acquisition of EBP knowledge and skills over time and with levels of increasing complexity through their participation in EBP courses and during their clinical practice experiences [ 32 , 33 , 34 , 35 ]. As Moch, Cronje, and Branson suggest, “It is only in such practical settings that students can experience the challenges intrinsic to applying scientific evidence to the care of real patients. In these clinical settings, students can experience both the frustrations and the triumphs inevitable to integrating scientific knowledge into patient care.” [ 35 ] (p. 11). Therefore, in future studies, other broad approaches for curriculum-wide integration of EBP as well as its long-term effects should be evaluated.

Previously in the Discussion, we highlighted the limitations of the proposed intervention in terms of time constraints (only 17 weeks), instructors’ constraints (only two instructors provided the intervention), and participants’ constraints (fourth-year undergraduate nursing students). In addition, the study was also restricted to one Portuguese nursing school, which can limit the generalization of the results. However, our study tried to address some of the fragilities identified in other studies [ 20 , 21 , 22 , 23 ] on the effectiveness of EBP educational interventions by including a control group and by measuring EBP knowledge and skills with an objective measure and not a self-reported measure.

Bearing this in mind, future studies in multiple sites should assess the long-term effects of the EBP educational intervention and the impact on EBP knowledge and skills of potential variations in contents and teaching methods. In addition, studies using more broad interventions for curriculum-wide integration of EBP should also be performed.

5. Conclusions

Our findings show that the EBP educational program was effective in improving the EBP knowledge and skills of undergraduate nursing students. Therefore, the use of an EBP approach as a complement to the research education of undergraduate nursing students should be promoted by nursing schools and educators. This will help to prepare the future nurses with the EBP knowledge and skills that are essential to overcome the barriers to EBP use in clinical settings, and consequently, to contribute to better health outcomes.

evidence based practice essay introduction

Background:

Nurses' ability to apply evidence effectively in practice is a critical factor in delivering high-quality patient care. Evidence-based practice (EBP) is recognised as the gold standard for the delivery of safe and effective person-centred care. However, decades following its inception, nurses continue to encounter difficulties in implementing EBP and, although models for its implementation offer stepwise approaches, factors, such as the context of care and its mechanistic nature, act as barriers to effective and consistent implementation. It is, therefore, imperative to find a solution to the way evidence is applied in practice. Evidence-informed practice (EIP) has been mooted as an alternative to EBP, prompting debate as to which approach better enables the transfer of evidence into practice. Although there are several EBP models and educational interventions, research on the concept of EIP is limited. This article seeks to clarify the concept of EIP and provide an integrated systems-based model of EIP for the application of evidence in clinical nursing practice, by presenting the systems and processes of the EIP model. Two scenarios are used to demonstrate the factors and elements of the EIP model and define how it facilitates the application of evidence to practice. The EIP model provides a framework to deliver clinically effective care, and the ability to justify the processes used and the service provided by referring to reliable evidence.

Evidence-based practice (EBP) was first mentioned in the literature by Muir-Gray, who defined EBP as ‘an approach to decision-making in which the clinician uses the best available evidence in consultation with the patient to decide upon the option which suits the patient best’ (1997:97). Since this initial definition was set out in 1997, EBP has gained prominence as the gold standard for the delivery of safe and effective health care.

There are several models for implementing EBP. Examples include:

  • Rosswurm and Larrabee's (1999) model
  • The Iowa model ( Titler et al, 2001 )
  • Collaborative research utilisation model ( Dufault, 2004 ); DiCenso et al's (2005) model
  • Greenhalgh et al's (2005) model
  • Johns Hopkins Nursing model ( Newhouse et al, 2005 )
  • Melnyk et al's (2010) model.

Although a comprehensive review of these models is beyond the scope of this article, a brief assessment reveals some commonalities among them. These include a) asking or selecting a practice question, b) searching for the best evidence, c) critically appraising and applying the evidence, d) evaluating the outcome(s) of patient care delivery, and e) disseminating the outcome(s).

Regardless of the benefits of EBP, and the existence of multiple EBP models intended to facilitate the application of evidence into practice, health professionals, including nurses, continue to struggle to implement it effectively ( Ubbink et al, 2013 ). Critics of EBP have questioned its validity ( Rubin, 2007 ; Nevo and Slonim-Nevo, 2011 ); the best practice and setting to support its use ( Nutley et al, 2009 ); its failure to address the complexity of health and health care, as well as the patient's context ( Muir-Gray, 1997 ; Reed et al, 2019 ), and its mechanistic approach ( Epstein, 2009 ; Jerkert, 2015 ). Some of these criticisms are outlined below.

For example, previous studies have reported the barriers health professionals face to successfully implement EBP. Ubbink et al (2013) conducted a systematic review to determine nurses' and doctors' views on knowledge, attitudes, skills, barriers, and behaviour required to implement EBP. The review included 31 studies from 17 countries: eight from North America and 11 from Europe. The results revealed that organisational and individual barriers prevent uptake of EBP among nurses and doctors. These barriers included the lack of material and human resources, and lack of support from managers and leaders; individual barriers included knowledge deficit regarding EBP, time and workload ( Ubbink et al, 2013 ). Researchers such as Hitch and Nicola-Richmond (2017) and Warren et al (2016) found similar barriers to implementing EBP reported by health professionals.

Effective and consistent implementation of EBP in healthcare settings depends on complex interdependent factors, such as the characteristics of an organisation (eg the internal and external healthcare environment, and organisational structures and values); the EBP intervention (eg reduction of hospital-acquired infections); and the attitudes of the individual practitioner towards EBP ( Titler and Everett, 2001 ; Cullen and Adams, 2012 ). Yet, existing approaches of EBP have been ineffective in facilitating its implementation ( Greenhalgh et al, 2014 ).

Consequently, authors such as Cullen and Adams (2012) and Greenhalgh et al (2014) have called for a resurgence of the concept, especially concerning the components of EBP associated with involving patients in decision-making, and with expert judgement and experience. Greenhalgh et al (2014:3) consider it is time to return to implementing ‘real EBP’, where person-centred care is the priority, and health professionals and their patients ‘are free to make appropriate care decisions that may not match what best evidence seems to suggest’. Nonetheless, researchers including McSherry et al (2002) , Epstein (2009) and Nevo and Slonim-Nevo (2011) have proposed an alternative, holistic approach to the application of evidence into practice, termed evidence-informed practice (EIP).

Journey towards evidence-informed practice

The problems with the uptake and effective implementation of EBP led to the emergence of the EIP concept. This concept is based on the premise that healthcare practice should, as a matter of principle, be informed by, rather than based on, evidence ( Nevo and Slonim-Nevo, 2011 ). This implies that other forms of evidence (for example, patient experiences, the nurse's expertise and experiences), not just the ‘research evidence’, should be considered in applying evidence in practice.

McSherry et al (2002) defined EIP as the assimilation of professional judgment and research evidence regarding the efficiency of interventions. This definition was further elaborated as an approach to patient care where:

‘Practitioners are encouraged to be knowledgeable about findings coming from all types of studies and to use them in an integrative manner, taking into consideration clinical experience and judgment, clients' preferences and values, and context of the interventions.’

Nevo and Slonim-Nevo (2011:18)

It has been over two decades since EIP emerged in the literature, however, primary research on the concept has been limited. Hence, although the term EIP has gained momentum in recent times, the methods needed to implement it effectively are not widely known ( McSherry, 2007 ; Woodbury and Kuhnke, 2014 ). While some proponents of EIP (eg Epstein 2011 ; Webber and Carr 2015 ) have identified significant differences between EBP and EIP, most researchers (eg Ciliska, 2012 ; Shlonsky and Mildon, 2014 ) have used the terms interchangeably.

Ciliska (2012) , for instance, developed an evidence-informed decision making (EIDM) module, but referred to the steps of EBP (ie Ask, Acquire, Appraise, Integrate, Adapt, Apply, Analyse) as the processes to be followed in implementing EIDM. Ciliska (2012) explained that the term EIDM was adopted to signify that other types of evidence are useful in clinical decision-making and to attempt to get beyond the criticisms of EBP. This notwithstanding, the author maintained the existing process for implementing EBP. Similarly, Shlonsky and Mildon (2014) used the terms EBP and EIP interchangeably, as they consistently referred to an EBP approach as EIP. Examples include referring to the steps of EBP as ‘the steps of EIP’ ( Shlonsky and Mildon, 2014:3 ) and referring to Haynes et al's (2002) expanded EBP model as a ‘revised EIP model’ ( Shlonsky and Mildon, 2014:2 ).

Another term that is often used interchangeably with EIP is ‘knowledge translation’. This term has been explored extensively. For example, the Canadian Institute of Health Research (CIHR) has adopted knowledge translation to signify the use of high-quality research evidence to make informed decisions ( Straus et al, 2009 ). The CIHR ( Graham et al, 2006 ) developed a ‘knowledge to action’ model intended to integrate the creation and application of knowledge. The model acknowledges the non-linear process of applying evidence in practice, where each stage is influenced by the next, as well as the preceding, stage. In a typical clinical setting, the actual process of applying evidence in practice is not linear, as acknowledged by the proponents of EBP, but cyclical and interdependent. Ciliska (2012) linked Graham et al's (2006) model to the components of evidence-informed decision-making. According to Ciliska (2012:7) , the knowledge-to-action model ‘fits with the steps of evidence-informed decision-making’. However, like EBP, the term ‘knowledge translation’, differs significantly from the EIP concept because it focuses on the ‘research evidence’ in decision-making.

The apparent confusion surrounding EIP is due to inadequate information about its components and the methods involved in implementing the concept. To foster a culture of EIP among health professionals, they must first be made aware of the actual components of the concept and the strategies involved in its successful implementation. The following section uses case scenarios to provide a description of the factors and elements of the EIP model and defines how it facilitates the application of evidence into clinical nursing practice.

Systems thinking

The clinical setting within which nurses work is a complex system made up of several interdependent and inter-related parts. Problems with healthcare delivery and management must therefore be perceived as a consequence of the exchanges between elements of the systems, instead of an outcome or the malfunctioning of a particular element. This, McSherry and Warr (2010) , have referred to as ‘systems thinking’.

Effective implementation of EIP demands an understanding of the various parts of the system that come together to aid the application of evidence in practice.

The evidence-informed practice model

The original model.

The earliest version of the evidence-informed practice model is depicted in Figure 1 . This was developed specifically for nurses and was originally named ‘the evidence-informed nursing model’. The model presented in Figure 1 was developed through PhD research conducted by Robert McSherry (2007) , with the aim to explore, through a mixed-methods study design, why the use of research as evidence in support of clinical nursing practice remains problematic. Study participants were registered nurses practising in a hospital trust located in north-east England.

evidence based practice essay introduction

The results of McSherry's (2007) study showed that, to effectively apply evidence in clinical nursing practice, nurses needed to be informed of, and be able to interact with, several key elements. The evidence-informed nursing model was developed as an alternative framework for facilitating the application of evidence in clinical nursing practice and was grounded in the principles and practices of systems thinking. This is because, primarily, the model provided an integrated process to applying evidence into practice, consisting of:

  • A clearly defined input; to encourage nurses to use evidence in practice
  • Throughput; facilitation of the processes associated with the elements
  • Output; improved standards of professional practice

The revised model

The evidence-informed nursing model has been adapted to the evidence-informed practice model. The new model ( Figure 2 ) is adapted in several ways. First, it has been modified to be all-inclusive, so it could be applied to any health profession. Second, the model has been simplified to show the interconnectedness of the various factors and elements that enable a professional to use evidence in support of their clinical decision-making. Third, the model demonstrates the ongoing complexity that health professionals find themselves working in, in the quest to apply evidence to clinical practice. Last, the EIP model incorporates the principles and components of EBP, which is particularly evident in the EIP cycle (the throughput phase of the model).

evidence based practice essay introduction

The factors and elements of the EIP model ( Figure 2 ) are explored in more detail below with reference to two scenarios, which are used to apply the EIP model to clinical nursing practice within both a scientific and the wider context within which nursing care takes place.

The first factor of the EIP model is ‘Factor 1. Drivers for evidence-informed practice’ ( Figure 2 ). In order for nurses to enhance patient care and experiences, along with improving their knowledge and skills of the patient's condition and associated signs and symptoms, they need to be aware of what EIP is, what it involves, and the principles required to make it happen. Applying the scenarios, it is essential that the nurse understands and can identify the key elements that drive successful implementation of the EIP concept. This is referred to as the drivers for EIP, which are illustrated in Figure 3 and discussed below.

evidence based practice essay introduction

Drivers for EIP

Staff selection.

Recruiting, interviewing and redeploying existing staff or hiring new staff are part of the staff selection process ( Dill and Shera, 2012 ). The importance of this driver is to identify personnel who qualify to implement the EIP programme or model. Additionally, it aims at selecting individuals within the organisation (for example coaches, supervisors, and trainers), who will ensure that the required organisational changes to support nurses in the effective implementation of EIP are done.

In-service training or pre-service

Training on EIP programmes involves activities that are related to offering instruction, providing specialist information or skills development in a structured manner to nurses and other key healthcare staff involved in the EIP programme. Nurses, as well as other members of staff, must learn when, how, where, and with whom to use new approaches and skills in applying evidence to practice ( Metz et al, 2007 ).

Coaching, supervision and mentoring

The coaching and mentoring approach enables new skills to be introduced to nurses on the ward with the support of a coach. The duty of a coach is to offer expert information and support, together with encouragement, opportunities and advice to practise and apply skills that are specific to the EIP programme. Effective implementation of human service interventions (such as EIP) requires changes in behaviour at administrative, supervisory and practitioner levels ( Dill and Shera, 2012 ). Coaching and mentoring are the main ways to bring about a change in behaviour for staff who have been successfully involved in the beginning stage of the implementation process and throughout the life of the EIP programme.

Systems-level partnership

This refers to the improvement of partnerships with the broader and immediate systems to ensure access to required funds, and institutional and human resources necessary to support nurses' work. The immediate systems-level partnership refers to working with individuals or organisations that directly influence healthcare delivery (for example, nurses and doctors).

Partnerships within the broader system, on the other hand, refer to policymakers, funders or other organisations that may support the EIP programme, but are not directly involved in delivering health care. A variety of activities may be conducted as part of the development of systems-level partnerships to aid the implementation of EIP. These may include fundraising activities to support the implementation of EIP programmes, as well as the use of external coaches and consultants to assist with mentoring, technical assistance and training on an ongoing basis.

Internal management support

This involves activities that are associated with establishing processes and structures within an EIP programme to enhance effective implementation of the programme. This is necessary in order to inform healthcare decision-making as well as keep staff organised and focussed on desired care outcomes ( Fixsen et al, 2005 ). Instances of internal management support include the formation of institutional structures and processes, the allocation of resources to support selection of suitable staff, and administrative support for efficient training.

Staff performance and programme evaluation

This involves evaluation of staff performance and the overall EIP programme to determine whether the objectives of the programme have been achieved. To do this effectively, it is important to evaluate the outcomes of the above-defined drivers, in particular, staff selection, in-service training, as well as coaching and mentoring. This will offer managers and stakeholders insight about the effectiveness of staff selection, training, and mentoring in facilitating the application of evidence into clinical practice ( Dill and Shera, 2012 ).

Elements of the EIP model

The first element of the EIP model is professional accountability, depicted as an ‘input’ in Figure 2 . This is an essential part of a nurse's roles and responsibilities and is reaffirmed in the nursing Code ( Nursing and Midwifery Council, 2018 ) of professional practice, the contract of employment and job description. In both case scenarios involving Mitchell and Yvonne ( Box 1 ), professional accountability is evident on several fronts: the nurse must establish a caring, compassionate and therapeutic relationship with the patients by involving and engaging them in shared decision-making regarding all aspects of their care, treatments, and interventions; the nurse is accountable and answerable to the patient and his or her professional colleagues throughout the patient's journey.

Box 1.Patient scenariosScenario 1Yvonne, aged 31, is admitted to the emergency medical unit following a visit to her GP for a non-healing wound to her right big toe. The GP also reported that Yvonne has had a recurring sore throat, extreme tiredness and a low white blood cell count.The GP requested an urgent investigation of these symptoms. Yvonne was placed in a side room for precaution.Scenario 2Mitchell, aged 58, arrives in the emergency department complaining of severe chest pain. He is diaphoretic (sweating excessively) and says his pain is radiating down his left arm and up into his jaw, and he adds that he feels nauseated. A few minutes after admission, he suffers a cardiac arrest.He is resuscitated and transferred to the intensive care unit. He is intubated, is placed on a ventilator and has a central line catheter in place.

Throughput: the evidence-informed practice cycle

The EIP cycle (located in the ‘throughput’ of Figure 2 ) involves the processes or methods through which nurses apply evidence in support of their decision-making in clinical nursing practice. This often occurs in a clinical nursing environment that is complex, constantly changing, and involves numerous members of the multidisciplinary team, patients and their family. Effective communication (verbal and written) is essential for ensuring that the various elements are interchanging, interconnecting and communicating between, and with, each other. For example, the case of Yvonne in scenario 1 ( Box 1 ) can be used as an example to underline the importance of good communication. It is important to explain to the patient and her family the reason for nursing her in a side room rather than the main ward. In this situation, avoiding and preventing cross-infection is essential to safeguard Yvonne from harm.

To ensure the EIP cycle proceeds effectively requires that the nurse (the health professional) acts as the conduit for the interplay between the different elements of the model (ie Element 2: informed decision-making; Element 3: research awareness; Element 4: application of knowledge; and Element 5: evaluation). These elements will be further explored.

Element 2. Informed decision-making

This involves two-way communication between the nurse and the patient(s), and is critical in ensuring there is a robust relationship (honesty, openness, transparency) founded on the principles of person-centred care ( McSherry and Warr, 2010 ). It reaffirms the ethical principle of a patient's right to make an informed decision about what is suitable for them, and takes into account their beliefs, values, priorities and personal circumstances. In case scenario 2, applying the EIP model, the critical care nurse will be expected to involve Mitchell's (the patient's) relatives, medical staff and other members of the healthcare team in making decisions about, for example, ventilator management and care of the central line catheter. However, decision-making in an intensive care unit can be complex, and some of the decisions may involve the nurse only. Similarly, applying the EIP model in case scenario 1, the nurse will be expected to communicate with the patient (Yvonne), carers and colleagues about the importance of hand hygiene, wound care and the importance of using precautions to avoid hospital-acquired infections when caring for the patient.

In both case scenarios, the nurse must endeavour to involve the patient/family members in the process of decision-making by providing them with timely, appropriate and relevant information needed to make often complex and life-changing decisions.

Element 3. Research awareness

This element refers to motivating practitioners to acquire skills and knowledge, as well as to conceptualise what research and evidence involves and the significance they have in improving standards of healthcare practice ( McSherry et al, 2006 ). Research awareness is reliant on the nurse's attitudes towards research, the acquisition of knowledge and confidence about the value of research to practice, and on having supportive managers and colleagues.

This element of the EIP cycle, contained within the model, incorporates three of the steps (Research awareness) of EBP: ask a clinical question, search the literature for research evidence to answer the question, and critically appraise the evidence obtained). Although the nurse is not required to be a researcher to implement the EIP model effectively, they must be knowledgeable about relevant databases and search engines (such as Medline and Google), as well as critical appraisal tools, in order to be able to include high-quality research evidence when making patient care decisions.

However, the EIP model acknowledges the fact that research evidence may not always be readily available, and nurses may not have the necessary hardware and software in the care environment to enable them to search for research evidence. Hence, recommendations by Greenhalgh et al (2014) led to inclusion, within the EIP model, of nurses as critical thinkers and doers which, therefore, allows them to make appropriate care decisions based on patient preferences and actions, the clinical state, clinical setting and circumstances, and advocates that nurses apply their own knowledge, expertise and clinical experiences in clinical decision-making, which may not necessarily match what the research evidence seems to suggest.

With reference to scenario 2 (and similarly for scenario 1), to adhere to the EIP model the nurse would take the following steps:

  • Update his/her knowledge about Mitchell's clinical presentation
  • Search Medline for research evidence on ‘chest pain’, and ‘cardiac arrest’ and its associated symptoms. Based on the number of articles obtained, the nurse reads the titles and abstracts, and then, the full text of selected articles to exclude irrelevant articles. The remaining articles are then critically appraised to include the best research evidence in patient care decisions.

In situations where the above steps are not possible, the model advocates that the nurse endeavours to make the best care decisions possible based on patient preferences, clinical state, context and circumstances, and the nurse's own expertise and experience, as well as the experience of the patient and family members where possible.

Element 4. Application of knowledge

This is a complex element that requires the gathering and assimilation of various sources of information, evidence, quality and standards, and policy and guidance, to support the nurse's decision-making in clinical practice. In relation to both scenarios, the nurse would need to:

  • Apply knowledge acquired from the patients (Mitchell and Yvonne), along with information from their relatives
  • Apply evidence from reviewing the findings from research
  • Take into account information gleaned from engaging with the multidisciplinary team
  • Ensure they follow recommended local and national guidance and policy on the management of each patient's condition.

It is imperative that the nurse is experienced, knowledgeable, and competent in order to make the most appropriate care decisions together with the patient, the family and the wider multidisciplinary team. To do this effectively, the nurse requires certain personal attributes, it is also important for the organisation within which the nurse works to have specific institutional characteristics. Institutional features include culture, education and training, and workload/skill mix, whereas personal characteristics include improved confidence, attitude, understanding and behaviour towards the application of evidence into practice.

Element 5. Evaluation

This element of the EIP cycle within the model measures the effects of decision-making and actions of the nurse on care outcomes and in creating an optimal care environment. In both scenarios, the nurse would need to periodically evaluate specific processes and outcomes of care. For example, with regards to scenario 2, this would include:

  • Monitoring how Mitchell is performing on the ventilator
  • Taking the necessary infection prevention precautions to avoid the development of infections related to the insertion of a central line and transmission of hospital-acquired infection
  • Monitoring improvement in Mitchell's general wellbeing.

Depending on the outcome of the evaluation, Mitchell's care plan would be either revised or continued.

Element 6. Conditions affecting research utilisation

Research utilisation involves critically appraising research findings, disseminating, and using the knowledge obtained from research to cause changes in an existing healthcare practice ( Titler et al, 1994 ). The conditions that affect research utilisation are grouped into five domains ( Wang et al, 2013 ):

  • The process involved in utilising research findings
  • Accessibility to research
  • The quality of research
  • The knowledge and attitudes of the nurse (health professional) regarding the use of research findings
  • The organisation within which the findings of research are to be implemented.

In the two scenarios ( Box 1 ), the nurse needs to be aware of the potential barriers to research utilisation and identify ways to overcome these in order to effectively apply evidence to healthcare practice. In addition, the clinical environment within which nurses work must provide sufficient support in order to enhance the effective and consistent application of evidence to practice. Nurses must be supported to acquire the necessary knowledge, skills, and understanding needed to practise safely (ie competently and confidently). In addition, the resources necessary to obtain research evidence, such as IT (computers and internet), must be readily available in the clinical setting for easy access to information.

Factor 2 (Output). Critical thinker and doer, the professional nurse

To ensure that nurses inform their decisions with the best available evidence, it is imperative that they have a sound understanding and knowledge of what constitutes the EIP model ( Figure 2 ). Successfully engaging with the various factors and elements of this model will lead to the desired outcome—that of a professional who is a critical thinker and doer, a professional nurse who, as argued by Brechin (2000:44) , is ‘knowledgeable and skilled, yet welcomes alternative ideas and belief systems, appreciating and respecting alternative views’. In this context, it is about creating a caring and compassionate environment in which excellence in nursing practice occurs. This can only be exemplified by ensuring that decisions and actions are based on the best available evidence.

The benefits of the EIP model for the nurse, patient and family are that it simplifies a highly complex series of systems and processes pertaining to how evidence is used to support decisions made in clinical practice. The EIP model simply illustrates the why, the how and the sequencing of getting evidence into clinical practice. It also complements the evidence-based movement by offering a holistic systems-based approach to facilitating the application of evidence into clinical practice.

EIP is a holistic integrated approach to applying evidence into practice, which incorporates the steps of EBP within its system and processes. In other words, EBP is a subset of the EIP model, made explicit within the EIP cycle. Thus, EIP is neither an alternative to, nor a replacement for, EBP. The EIP model provides a framework for nurses (indeed all health practitioners) to deliver clinically effective care and enable them to justify the processes used and the service provided by referring to reliable evidence. Using two scenarios, this article demonstrated how the EIP model can be applied to clinical nursing practice. Future initiatives should focus on developing EIP educational interventions and determining the effects of such interventions on healthcare students' knowledge of, and attitudes towards, the application of evidence to practice.

  • Two main concepts have been associated with the application of evidence into practice: evidence-based practice (EBP) and evidence-informed practice (EIP)
  • The main feature that distinguishes EIP from EBP is the processes used in implementing the concepts
  • EIP provides the mechanisms or processes to follow in implementing EBP
  • EIP is not a substitute or replacement for EBP. EIP is an integrated approach to applying evidence to practice, which incorporates the steps of EBP in its processes

Essay on Evidence-Based Practice

Since its official introduction in 1992, Evidence-based practice (EBP) has gained lots of ground. It is the process of assembling, processing, and applying research results to improve clinical practice, the work setting, and patient outcomes. The clinical practice’s approach is currently used in other fields such as nursing, education, and psychology. This paper aims to discuss evidence-based practice, identify two of its trails, and analyze how they influence care delivery.

The measuring of blood pressure noninvasively in children is a good initiative for the prevention of hypertension. High blood pressure in children and adolescents has emerged as a public health issue, primarily driven by obesity’s widespread in the current population. (Stergiou, 2017). The main approaches for measuring blood pressure noninvasively are the auscultatory method using an aneroid device and the automated process using oscillometric devices. Auscultatory BP measurement confirms elevated BP after detection via an electrical BP monitor. The auscultatory BP measurement encounters several complications in children, majorly due to anatomic and bodily features of the undeveloped persons.

In contrast, Automated BP measurement in children has been disputed by researchers. An experiment done by Jaime Miranda in Peru on children suggested that blood measured by the oscillometric device was poorly connected; hence the use of automated blood pressure devices was concluded to have limitations and not recommended. (Miranda, 2009). Therefore, using the auscultatory method and eventually comparing the measurement against obtained data with the oscillometric form is a proper initiative to providing better care than using the processes separately.

Valuing the role of family members is also a beneficial initiative to the well-being of patients. It is estimated that 50% of healthy patients aged 65 or older have family involvement in their health care. Family members can play several roles, determined by factors such as the patient’s disease and healthcare decisions to be well-thought-out. In a study on patients with lung cancer, Siminoff discovered that their families counselled 17% of the patients to change doctors during treatment of the ailment, mainly because they were unhappy with their specialist’s style of communication (Siminoff, 2013).

Clinicians should contemplate the part family and friends play and their impact on the patient’s treatment choice. By recognizing family members input, care may be more effective and efficient. They may have a superior influence on how patients present their illnesses to doctors and the type of treatment they pursue or accept excluding those reinforced by evidence-based research. Hence, considering these influences will aid nurses to apply evidence-based research to its maximum potential.

In conclusion, Evidence-based practice is undoubtedly an operative practical approach to handling treatment. By reviewing and assessing the most recent, uppermost quality research, practitioners in healthcare deliver the best of care to patients. Based on research, using Auscultatory BP measurement to confirm elevated BP after detection by an electronic BP monitor is an operative initiative for treating hypertension in children. In addition, acknowledging the role of family members on patients results in care delivery be that of extreme quality. Studying and understanding this practice is thus vital for healthcare practitioners.

The Evidence-Based Practice Assessment Essay

Introduction, assessment of evidence-based practice implementation.

Implementing evidence-based practice (EBP) leads to change, and it is crucial to understand its impact and achievements. Assessment is a critical part of measuring progress and results obtained. Traditionally, two types of assessments are distinguished – formative and summative (Bin Mubayrik, 2020). The current paper compares both approaches, their objectives, and potential applications in the EBP project aimed at preventing central line-associated bloodstream infections. Even though formative and summative assessments application have different purposes and features, it is crucial to use both these approaches for one EBP project simultaneously.

Formative and summative assessments include various measures, which are used depending on the circumstances. La Chimea et al. (2020) unite both approaches when describing assessment techniques and mention multiple-choice questions, objective-structured clinical examinations (OSCEs), tests, exams, simulations, and other measures. Their research focuses significantly on educational settings, and while the EBP includes elements of employee training, it is also essential to consider that the project takes place in a clinical setting. Elwy et al. (2020) investigate the features of formative assessment when implementing changes in the hospital and note that this approach uses the same methods as the summative one. Researchers include such measures as interviews, task monitoring, exploring patients’ outcomes, and stakeholder surveys (Elwy et al., 2020). It is essential to understand approaches’ features to choose the proper technique for the EBP.

Formative and summative approaches to evaluation have differences that affect their application. According to Elwy et al. (2020), while the methods may be the same for different types of assessment, the timing and purpose of using the obtained data are different. Formative techniques are used during the project by the team responsible for its implementation to adapt and improve the process (Elwy et al., 2020). Assessment of this type is considered a continuous process; therefore, various measures are taken several times to monitor performance (Bin Mubayrik, 2020). Summative measures, in turn, are taken at the end of the project to explore what results have been obtained (Bin Mubayrik, 2020). Each of these approaches will be useful for the EBP, make it more productive, and help assess the achievement of goals.

Different assessment measures will be applied depending on the EBP phase. Using a formative approach, a suitable technique is to regularly monitor nurses’ compliance with the rules regarding catheter placement during the project implementation. This measure will allow tracking progress and gradual improvement in practice. Following the summative approach, tests will be applied after the project, checking the competence of nurses to comply with infection prevention protocols. This technique will help understand whether the goals of EBP have been achieved and whether employees have received the necessary knowledge and skills. Therefore, the EBP project needs both formative and summative assessments.

Thus, the assessment is an integral part of implementing the EBP. Its two types, formative and summative, can use the same methods to collect data, but their goals differ. Measures may include interviews, tests, exams, surveys, and other forms. The formative approach is needed to control and improve processes during project implementation. Summative methods are used to assess achievements after transformations are completed. Given their features, both types of assessments will benefit the EBP project. The formative technique of monitoring the execution of tasks during implementation will help make the process more efficient. Summative tests will assess the results and compliance with the set goals.

Throughout this book, we have attempted to show how to implement the evidence-based practice (EBP) decision-making process in a way that feels manageable and realistic in everyday clinical practice. We hope that the previous chapters have provided practitioners with the tools and the knowledge necessary to have confidence in their ability to use EBP to inform practice decisions in many settings and with a wide range of clients. While EBP is a process with both strengths and limitations, we believe that social workers must engage with EBP as a way of providing the best possible care to the clients they serve. Evidence-based medicine (EBM) and EBP are valuable steps toward realizing Dr. Archie Cochrane’s goals of increasing effective treatments, reducing benign treatments, and eliminating harmful and ineffective treatments. EBP is an important step in improving client outcomes and professional accountability. EBP moves social work from the “empirically based practice” world of single case outcome evaluation into the realm of large-scale, experimentally based, outcome research.
