Comparative effectiveness research (CER) compares the effectiveness of two or more health care interventions. By making direct comparisons between a particular technology or treatment and an established standard of care or other realistic comparator, CER assesses how well a health care treatment or intervention works under real-world conditions.
The Lewin Group Center for Comparative Effectiveness Research provides independent, data-driven, evidence-based policy recommendations regarding approaches for implementing CER and its impact.
We work with government, private sector, and academic institutions to establish CER programs, design and facilitate appropriately conducted research, communicate CER findings, and provide access to data sets required for sound CER programs.
