Evidenciaalapú

Evidenciaalapú, usually translated as evidence-based in Hungarian, denotes approaches and decisions grounded in the best available evidence rather than tradition, authority, or anecdote. It is most common in health care, but is also applied in education, policy, and management.

Origins and core idea: The concept emerged prominently in evidence-based medicine in the 1990s, associated with Gordon Guyatt and colleagues at McMaster University, who defined it as the disciplined integration of the best research evidence with clinical expertise and patient values.

Principles and methods: The evidence is gathered through systematic reviews and, where possible, meta-analyses; randomized controlled trials are highly valued; quality is appraised and graded, e.g., using the GRADE framework; guidelines synthesize evidence for practice.

Applications: In medicine, evidence-based practice informs patient care; in public health and policy to guide interventions and resource allocation; in education to shape curricula; and in management and business decisions as well.

Challenges: Evidence varies in quality; applicability to individual patients can be limited; there is a risk of overreliance on randomized trials or ignoring context; publication bias can distort the available evidence; there is a need for ongoing updates and attention to patient preferences to avoid rigid, cookbook approaches.

The evidenciaalapú approach supports transparent, patient-centered decision making and the use of rigorously synthesized research to guide practice.
