Public Health Service Agencies: Overview and Funding (FY2016-FY2018) [August 16, 2017] [open pdf - 1MB]
"The Department of Health and Human Services (HHS) has designated 8 of its 11 operating divisions (agencies) as components of the U.S. Public Health Service (PHS). The PHS agencies are (1) the Agency for Healthcare Research and Quality (AHRQ), (2) the Agency for Toxic Substances and Disease Registry (ATSDR), (3) the Centers for Disease Control and Prevention (CDC), (4) the Food and Drug Administration (FDA), (5) the Health Resources and Services Administration (HRSA), (6) the Indian Health Service (IHS), (7) the National Institutes of Health (NIH), and (8) the Substance Abuse and Mental Health Services Administration (SAMHSA). The PHS agencies all provide and support essential public health services; however, their specific missions vary. With the exception of FDA, the agencies have limited regulatory responsibilities. Two of them--NIH and AHRQ--are primarily research agencies. NIH conducts and supports basic, clinical, and translational medical research. AHRQ conducts and supports research on the quality and effectiveness of health care services and systems."
