Towards evidence-based clinical practice: an international survey of 18 clinical guideline programs

Abstract

Principles of evidence-based medicine dominate current guideline programs. Recent programs are benefiting from the methodology created by long-standing programs. Differences are found in the emphasis on dissemination and implementation, probably due to differences in health care systems and political and cultural factors. International collaboration should be encouraged to improve guideline methodology and to globalize the collection and analysis of evidence needed for guideline development.
