Many US hospital-affiliated freestanding ambulatory surgery centers are located on hospital campuses, relevant to interpretation of studies involving ambulatory surgery
The US Agency for Healthcare Research and Quality's State Ambulatory Surgery Database includes procedures performed at hospital outpatient surgery departments. We hypothesized that, among US hospitals with an anesthesia department and freestanding outpatient surgical center, the prevalence on hospital campuses (i.e., within 250 yards of the main hospital building) would be sufficiently large (e.g.,>10%) to influence interpretation of observational studies performed with US national ambulatory surgery datasets.
