Evidence-based public health: why it is important and how it differs from evidence-based clinical medicine
Abstract
The aim of the article is to summarise the main principles of evidence-based public health and to define in which particular ways it differs from evidence-based clinical medicine. The paradigm of evidence-based medicine has dominated clinical practice for 30 years.
However, the evidence-based approach should also be applied in public health practice and based on a synthesis of the best available evidence, applicable theoretical models, professional experience and in-depth knowledge of a specific population, including adaptation to its preferences. Scientific argumentation should employ systematic work with data and information systems whilst evaluating large population units.
The outputs are widely used in the creation of health programmes and policies. Final decisions are usually reached by consensus, so it is appropriate to get acquainted with the methodology of consensual methods.
Public health professionals at all levels should be continually trained in evidence-based practice.
