Institute of Medicine, 2009

CER is the generation and synthesis of evidence that compares the benefits and harms

of alternative methods to prevent, diagnosis, treat and monitor a clinical condition or to

improve the delivery of care. 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 level.
