Strengths and Limitations
Strengths Only state-level hospital database containing charge information on all patients, regardless of payer, and the uninsured. Data is weighted to determine national estimates. Patient severity adjustment is available. Comprehensive documentation and training available through AHRQ. Data can be linked with other datasets like American Hospital Association (AHA) survey, and Area Resource File (ARF). Trend analysis can be conducted
Limitations Information is collected from only participating states. Information is limited to inpatient stays. Clinical details are limited (e.g., intensity of rehabilitation intervention).
