An Inventory Of Federally Sponsored HIV And HIV-Relevant Databases. National Survey of Ambulatory Surgery (NSAS)


The National Survey of Ambulatory Surgery (NSAS) complements the NHDS by providing data on the increasing variety of surgical and diagnostic treatments performed outside the inpatient setting. The NSAS provides data on visits to freestanding and hospital-based ambulatory surgery centers. Data include patient demographic characteristics, diagnoses, surgical operations, and diagnostic procedures performed, patient disposition, and expected sources of payment. The NSAS was conducted from 1994 to 1996.
