Observational studies in systemic reviews of comparative effectiveness: AHRQ and the Effective Health Care Program
Systematic reviewers disagree about the ability of observational studies to answer questions about the benefits or intended effects of pharmacotherapeutic, device, or procedural interventions. This study provides a framework for decision making on the inclusion of observational studies to assess benefits and intended effects in comparative effectiveness reviews (CERs).AHRQ Series Paper 5: Grading the strength of a body of evidence when comparing medical interventions—Agency for Healthcare Research and Quality and the Effective Health-Care Program
To establish guidance on grading strength of evidence for the Evidence-based Practice Center (EPC) program of the U.S. Agency for Healthcare Research and Quality.AHRQ Series Paper 1: Comparing medical interventions: AHRQ and the Effective Health-Care Program
In 2005, the Agency for Healthcare Research and Quality established the Effective Health Care (EHC) Program. The EHC Program aims to provide understandable and actionable information for patients, clinicians, and policy makers. The Evidence-based Practice Centers are one of the cornerstones of the EHC Program. Three key elements guide the EHC Program and thus, the conduct of Comparative Effectiveness Reviews by the EPC Program. Comparative Effectiveness Reviews introduce several specific challenges in addition to the familiar issues raised in a systematic review or meta-analysis of a single intervention.
