Dataset: American Hospital Association (AHA)

Basic Information
Dataset full name: American Hospital Association
Dataset acronym AHA
Summary The AHA annual survey of hospitals in the United States is administered online. The survey is comprised of questions related to the following domains: organization structure (e.g., ownership status, services provision, and national identifiers); facilities and services provided (by institutions itself, through contracts, by other partnering facilities); total facility beds, utilization, finances, and staffing (beds and length of stay, source of payment, revenues and expenses, assets, non-reimbursed care, information technology investment, staffing information); community benefits; and management diversity. The AHA can be used independently or through linkages with other CMS and non-CMS datasets to report trends, performance, and quality indicators.

Strengths and limitations
Strengths Comprehensive information about hospitals/providers, Ideal for building nested and hierarchical models. Data can be linked with other CMS/non-CMS datasets. Good resource for Health-policy research related data.
Limitations Documentation and variable information is limited. Reasons for changes in structure of a facility (provider) are undocumented. Utility as stand-alone datasets is limited.
