Evidence-Based Medicine
Evidence-based medicine is a systematic clinical framework that integrates the best available research evidence with clinical expertise and individual patient values to guide diagnosis, treatment, and healthcare policy.
Overview
Developed prominently in the early 1990s by Gordon Guyatt and colleagues at McMaster University, it formalized a shift from decisions based on authority and tradition toward those grounded in rigorous empirical data, establishing hierarchies of evidence that rank randomized controlled trials and systematic reviews above observational studies and expert opinion.
Why it matters
The widespread adoption of evidence-based medicine fundamentally transformed medical education, hospital protocols, regulatory standards, and clinical research design; by making patient outcomes the ultimate measure of clinical validity, it directly reduced the prevalence of ineffective or harmful treatments that had persisted through convention, representing a major epistemological advance in healthcare.
