Comparative Effectiveness Research
Designed to inform healthcare decisions by providing evidence on the effectiveness, benefits, and harms of different treatment options. The evidence is generated from research studies that compare drugs, medical devices, tests, surgeries, or ways to deliver health care. The core question of comparative effectiveness research is which treatment works best, for whom, and under what circumstances. The purpose of CER is to assist consumers, clinicians, purchasers, and policy makers to make informed decisions that will improve health care at both the individual and population levels.
