Comparative Effectiveness Research

Comparative effectiveness research (CER) is the conduct and synthesis of research comparing the benefits and harms of different interventions and strategies to prevent, diagnose, treat and monitor health conditions. The goal of CER is to improve health outcomes by developing and disseminating evidence-based information to patients, clinicians, and other decision-makers, responding to their expressed needs, about which interventions are most effective for which patients under specific circumstances. CER uses a wide range of research methods, including randomized controlled trials, observational studies, and systematic reviews, a structured assessment of evidence available from multiple primary studies.
