Nearly 5,000 hospitals, health care systems, networks, other providers of care and 43,000 individual members come together to form the AHA. Through our representation and advocacy activities, AHA ensures that members' perspectives and needs are heard and addressed in national health policy development, legislative and regulatory debates, and judicial matters. Our advocacy efforts include the legislative and executive branches and include the legislative and regulatory arenas. The AHA provides education for health care leaders and is a source of information on health care issues and trends.
