Comparative Effectiveness Research (CER):
A type of health care research that compares the results of one approach for managing a disease to the results of other approaches. CER usually compares two or more types of treatment for the same disease. CER is designed to inform health care decisions by providing evidence on the effectiveness, benefits, and harms of different treatment options.
Patient Centered Outcomes Research (PCOR):
Helps people and their caregivers communicate and make informed health care decisions. PCOR actively engages patients and key stakeholders throughout the research process; compares important clinical management options; evaluates the outcomes that are most important to patients; and addresses implementation of the research findings in clinical care environments.
