About the Agency for Health Care Research and Quality
The AHRQ - formerly the Agency for Healthcare Policy and Research - is part of the U.S. Department of Health and Human Services. The agency's primary role involves supporting research to improve the quality of health care, reduce cost and broaden access to essential services. The AHRQ also strives to compile and disseminate information that aids in the development of clinical practice guidelines and disease-management programs.
