The goal of EBP in healthcare is to promote improved interventions, care, and patient outcomes.Johns Hopkins Evidence-Based Practice for Nurses and Healthcare Professionals has proven to be one of the most foundational books on EBP in nursing and healthcare. Building on the strength of previous versions, the fourth edition is fully revised to include updated content based on more than a decade of the model's use, refinement in real-life settings, and feedback from nurses and other healthcare professionals around the world.Key features of the book include:* NEW strategies for dissemination, including guidance on submitting manuscripts for publication* EXPANDED focus on the importance of interprofessional collaboration and teamwork, particularly when addressing the complex care issues often tackled by EBP teams* EXPANDED synthesis and translation steps, including an expanded list of outcome measures to determine the success of an EBP project* Tools to guide the EBP process, such as stakeholder analysis, action planning, and dissemination* Explanation of the practice question, evidence, and translation (PET) approach to EBP projects* Overview of the patient, intervention, comparison, and outcome (PICO) approach to EBP question development* Creation of a supportive infrastructure for building an EBP nursing environment* Exemplars detailing real-world EBP experiences

The JHNEBP Model is a powerful problem-solving approach to clinical decision-making, and is accompanied by user-friendly tools to guide individual or group use. It is designed specifically to meet the needs of the practicing nurse and uses a three-step process called PET: practice question, evidence, and translation. The goal of the model is to ensure that the latest research findings and best practices are quickly and appropriately incorporated into patient care.
This worksheet can help you identify the PICO elements of your research question. PICO is an initialism for patient, problem, or population, intervention or exposure, comparison or control, and outcome. Variations on PICO exist, such as PICOT (Time) or PICOS (Study Type).
If your question doesn't fit into the PICO framework, review our Formulating Your Research Question page on our Expert Searching Guide.
When setting out to do an EBP project, you'll need to have a well-developed research question. The JHNEBP Model's Appendix A - PET Process Guide, supplies you with a checklist to ensure that you have thought through all the steps and have a winning team in place prior to the start. PET stands for Practice Question, Evidence, Translation.
When framing the EBP question, consider ideas such as:
Is your question a background question or a foreground question?
Background Questions - These are usually broad and used in the beginning. Background questions can be refined and adjusted as continue to develop the search. Background questions frequently assist in identifying best practices.
Foreground Questions - These types of questions are focused, with specific comparisons of ideas or interventions. Foreground questions can provide specific evidence related to the research question. Background questions can turn into foreground questions as the review progresses.
This process can be identified in the JHNEBP Model, Appendix B - Question Development Tool PICO. After you've completed Appendix A and Appendix B, complete Appendix C - Stakeholder Analysis and Communication Tool. This form is used to identify key stakeholders that can support decision-making, serve as subject matter experts, or implement change.
To find the evidence, you will need to search for it. It will depend on what resources you have access to through your institution, but it is always a best practice to search more than one resource. This is because different resources index different topics and journals.
The section of this guide called Databases and Clinical Tools lists important databases for nursing research.
Use your question framework or JHNEBP Question Development Tool to determine the major elements of your question. Think about how authors might write about these concepts. There may be many terms to describe just one idea.
See the Welch Library's Expert Searching Guide for more tips and tricks on how to become an expert searcher.

The Centre for Evidence Based Medicine at the University of Oxford provides worksheets and calculators to assess systematic reviews, diagnostic, prognosis, and RCT article types. See their specific Critical Appraisal tools.
Dartmouth provides a series of worksheets designed to aid you in formulating clinical questions, appraising the evidence, and applying the evidence to practice.
CASP provides worksheets to appraise randomized control trials, systematic reviews, cohort studies, case control studies, qualitative research, economic evaluations, diagnostic tests, and clinical prediction rules.

JBI's critical appraisal tools assist in assessing the trustworthiness, relevance, and results of published papers.
This set of eight critical appraisal tools are designed to be used when reading research, these include tools for Systematic Reviews, Randomised Controlled Trials, Cohort Studies, Case Control Studies, Economic Evaluations, Diagnostic Studies, Qualitative studies and Clinical Prediction Rule.

The Grading of Recommendations Assessment, Development and Evaluation (short GRADE) working group began in the year 2000 as an informal collaboration of people with an interest in addressing the shortcomings of grading systems in health care. The working group has developed a common, sensible and transparent approach to grading quality (or certainty) of evidence and strength of recommendations.
The Newcastle-Ottawa Scale (NOS) is an ongoing collaboration between the Universities of Newcastle, Australia and Ottawa, Canada. It was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the quality assessments in the interpretation of meta-analytic results.
The OHAT Risk of Bias Rating Tool can be used for human and animal studies.
The CEBM Levels of Evidence framework sets out one approach to systematizing this grading process for different question types.
This tool is based on the Cochrane RoB tool and has been adjusted for aspects of bias that play a specific role in animal intervention studies.
The U.S. Preventive Services Task Force (USPSTF) assigns one of five letter grades (A, B, C, D, or I). The USPSTF changed its grade definitions based on a change in methods in May 2007 and again in July 2012, when it updated the definition of and suggestions for practice for the grade C recommendation.
Now it's time to critically appraise and take action on the evidence you found through the search. The JHNEBP Model has several tools available to help you grade the evidence and see the process through to the finish line.
