Medical imaging and radiation sciences: Evidence-based practice

Guide to information resources and services for Medical imaging and radiation sciences

What is evidence-based practice?

Evidence-based practice (EBP) is the process of making clinical decisions based upon research evidence, combined with clinical experience and patient preferences.

EBP is used in a variety of fields, including medicine, nursing and allied health.

Key resources for evidence-based practice

Best Practice contains current information on prevention, treatment, diagnosis and prognosis for specific conditions. Mobile device access.

ACP Journal Club provides summaries of key studies and systematic reviews in internal medicine.

Cochrane Library includes controlled trials, systematic reviews and economic evaluations. Access is free for all Australian residents.

Ovid Medline covers medicine, nursing, allied health and pre clinical sciences.

PubMed Clinical Queries filter search results by most appropriate study designs

TRIP is a clinical search engine.

Clinical Practice Guidelines portal Australian clinical practice guidelines

EBM Reviews integrates clinical expertise with systematic research, especially in relation to the effects of health care.

Levels of evidence

Certain types of evidence are considered more reliable than others. For example, a randomised controlled trial is considered stronger evidence than an individual case study. Cochrane systematic reviews are commonly considered the 'gold standard' for evidence.

See the hierarchy of evidence of study designs at the excellent Duke University Medical Center Library website.

Applying the evidence

Critically evaluate the evidence you find, and use it to support your clinical decisions, taking into account your clinical experience and patient preferences. The Centre for Evidence Based Medicine, Oxford, has excellent critical appraisal checklists.
