The SASD are State-specific files that capture surgery records in which patients are admitted and discharged in the same day from ambulatory surgery sites. The uniform format of the SASD helps facilitate cross-state comparisons. In addition, 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.
