Evidence-based practice

What's the difference between "evidence-based practice" and "evidence-based medicine"?

It's all about the evidence, the research and the patient.

Evidence-based practice (EBP) is used widely by allied health professionals and is the conscientious use of current best evidence in making decisions about patient care (Sackett & Rosenberg 1996). It uses clinical decision‐making that combines research evidence, clinical expertise, and patient preferences and characteristics.

Evidence-based medicine (EBM) considers the patients views and integrates the best research evidence and clinical expertise when making a decision. (Guyatt G, et al 1992).

Evidence‐based practice stems from evidence-based medicine (EBM), however, it's interdisciplinary and used in the fields of allied health, education, psychology and others. 

You will come across both EBP and EBM throughout your studies or research in Medicine and Health. Below are databases that are entirely about EBP and EBM.

Search and keep track of the evidence for your systematic literature review using these resources:

PRISMA is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses.

Use a framework like PICO when developing a good clinical research question:

PICO framework
P I C O
Patient or Problem Intervention Comparison Intervention Outcome
Describe as accurately as possible the patient or group of patients of interest. What is the main intervention or therapy you wish to consider? Is there an alternative treatment to compare? What is the clinical outcome?

PROSPERO is an international register for prospective systematic literature reviews.

  • Includes protocol details for systematic reviews relevant to health, social care, welfare, public health, education, crime, justice, and international development (where there is a health related outcome).
  • Protocols can include any type of any study design.
