Since 1946, the American Hospital Association has collected data provided by the nation’s hospitals and health care systems to give researchers the most consistent and complete view of trends.
AHA Data is the research community’s destination for reliable, historic hospital data:
- Data from more than 6,200 hospitals and 400 health care systems
- Use it as a single reference or seamlessly match it to other public data sets to expand your analysis
- Examine hospital characteristics against health care transformation and policy changes
- Explore physician models by hospital size, ownership-type, and geography
- Identify the change in hospital and health care system affiliation over time
- Identify the types of hospitals adopting bundled payment models, and establishing medical homes

"AHA Data played a pivotal role in jumpstarting my project during the COVID-19 pandemic. My focus centered on examining the prevalence of telehealth services among U.S. hospitals and clinics within my clinical specialties of pulmonary and critical care. The invaluable insights provided by the AHA's Annual Survey Database enabled me to pose the right questions and proved critical to this research."
