Comparative Effectiveness Research

As an advocate for evidence-based research and informed decision making, the AOA is an official partner of the U.S. Department of Health and Human Services Agency for Healthcare Research and Quality (AHRQ). AHRQ is the lead federal agency charged with improving the quality, safety, efficiency and effectiveness of health care for all Americans. It supports health services research to improve the quality of health care and promote evidence-based decision making.  

Patient-centered outcomes research, also known as comparative effectiveness research, compares drugs, medical devices, tests, surgeries, or ways to deliver health care. The research findings do not tell physicians how to practice medicine or which treatment is best. Instead, AHRQ products are designed to clearly communicate treatment options’ benefits, harms, and side effects, for physicians and patients to have evidence-based information when making individual treatment decisions.  

Free Tools and Resources

The AOA is pleased to provide the free research reports and tools available from AHRQ to help physicians educate patients about common conditions and to provide patients the necessary information to make informed decisions about their care. See available resources listed in right sidebar.

Research is available for a number of health conditions, including cardiovascular and related diseases, diabetes, arthritis, mental health disorders, digestive conditions, cancer and pregnancy.
