The Health Resources and Services Administration (HRSA) is an agency of the U.S. Department of Health and Human Services located in North Bethesda, Maryland. It is the primary federal agency for improving access to health care services for people who are uninsured, isolated or medically vulnerable. Comprising six bureaus and twelve offices, HRSA provides leadership and financial support to health care providers in every state and U.S. territory. Its grantees provide health care to uninsured people, people living with HIV/AIDS, and pregnant women, mothers and children. They train health professionals and improve systems of care in rural communities. HRSA oversees organ, bone marrow and cord blood donation. It supports programs that prepare against bioterrorism, a program to compensate people who experience vaccine adverse events, and maintains databases that protect against health care malpractice and health care waste, fraud and abuse. Functions HRSA's $10 billion budget (FY 2015) provides direct health care to 23 million people. Its health center program supports medical, oral and behavioral health services to uninsured and underinsured individuals through a nationwide network of community-based clinics and mobile medical vans. By bringing comprehensive primary and preventive health care services to inner-city and rural communities that otherwise would be without them, health centers improve the health of their communities and relieve pressure on overburdened hospital emergency rooms. The agency also recruits doctors, nurses, dentists and others to work in areas with too few health care professionals. HRSA funds life-sustaining medication and primary care to about half of the estimated number of people living with HIV/AIDS in the United States. The agency also furnishes funds and expertise that save and improve the lives of millions of mothers and children. HRSA also oversees all organ, tissue, and blood-cell donations. It is the federal agency primarily responsible for pediatric poison control. It also maintains databases that track cases of health care malpractice and compensates individuals judged to be harmed by vaccinations. HRSA monitors trends in the health care workforce and forecasts future demand. Scholarships and academic loan programs encourage greater minority participation in the health professions and seek to maintain an adequate supply of primary care professionals.
