SASD Database Documentation
The SASD are a set of longitudinal State-specific ambulatory surgery and services databases included in the HCUP family. These databases are created by AHRQ through a Federal-State-Industry partnership.
State Ambulatory Surgery and Services Databases (SASD)

The SASD are State-specific files that include data for ambulatory surgery and other outpatient services from hospital-owned facilities. In addition, some States provide ambulatory surgery and outpatient services from nonhospital-owned facilities. The uniform format of the SASD helps facilitate cross-State comparisons. The SASD are well suited for research that requires complete enumeration of hospital-based ambulatory surgeries within geographic areas or States. The following links provide detailed database documentation for the SASD.
