To measure the incidence of intraoperative hypotension (IOH) during surgery in ambulatory centers (ASCs) and describe associated characteristics patients procedures.Retrospective analysis.20 ASCs.16,750 having non-emergent, non-cardiac surgery; ASA physical status 2 through 4.None.We assessed IOH using definition from Centers for Medicare & Medicaid Services (CMS) Merit-based Incentive Payment System (MIPS)-mean arterial pressure (MAP) < 65 mmHg at least 15 cumulative minutes-and three secondary definitions: minutes MAP <65 mmHg, area under time-weighted average mmHg.30.9% ASC cases had a min. The varied significantly, was higher among younger adults (age 18-39; 36.2%), females (35.2%), with (32.8%). increased increasing length, even when time-weighted, low complexity (30.6%) than moderate (28.8%) procedures, highest high procedures (44.1%).There substantial occurrence ASCs, similar to that described academic hospital settings previous literature. We hypothesize this may reflect clinician preference not intervene perceived healthy or assumptions about ability tolerate lower blood pressures on behalf these patients. Future research will determine whether ACSs is adverse outcomes same extent as more complex hospital-based surgeries.
