Although traditionally performed in an inpatient (IP) setting, interest in these surgeries being done as an outpatient (OP) and ambulatory surgery center (ASC) settings has increased. We compared costs and post-operative complication rates for AA performed across these settings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      Using Medicare fee-for-service claims (2016-2021), we retrospectively identified patients \u226565\u2009years of age who underwent AA.

We also evaluated total episode and post-acute care costs within 90 days. We tested for differences in perioperative safety indicators and costs through multivariate regressions, controlling for age, sex, race, and Charlson Comorbidity Index (CCI), dementia, and the involvement of a surgical assistant. A propensity-matched analysis was performed to minimize selection by indication bias.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      We included 7104 initial AA cases across surgical settings: 262 (3.7%) in ASC, 3047 (42.9%) in OP, and 3795 (53.4%) in IP.
