BACKGROUNDS: Publicly funded obesity surgery remains underfunded in Australia. One barrier to expansion is the perception that perioperative care requires critical care facilities. This study evaluates the effectiveness of patient selection criteria in avoiding unplanned patient transfer and adverse outcomes in obesity surgery performed at a facility without a high-dependency unit/intensive care unit (HDU/ICU). METHODS: Retrospective analysis was performed on patients undergoing obesity surgery between January 2017 and March 2020 in a centre with specific screening criteria. Criteria included: body mass index <48 for males and <52 for females with up to three stable comorbidities from a selected list. Revision sleeve or bypass procedures were contraindicated. Primary outcome was patient transfer to our main campus. Secondary outcomes included return to theatre (RTT), readmission and death. Outcomes were compared to laparoscopic cholecystectomies (LC) performed at the same centre. RESULTS: A total of 387 obesity surgery procedures were performed; 372 patients (96%) were discharged without complication. Fifteen (3.9%) were transferred to the main campus, eight were admitted to ICU and two required re-operation. Twelve (3.1%) were readmitted within 30 days of discharge, five required re-operation. Transfer, 30-day readmission and 30-day emergency department presentation rates were similar in comparison to LC. RTT during index admission (0.5% vs. 3.0%; p = 0.006) and during 30-day post-operative period (1.8% vs. 4.4%; p = 0.025) was lower in the obesity surgery group. CONCLUSION: Carefully selected screening criteria allow obesity surgery to be performed at a well-supported non-HDU/ICU facility with few complications and acceptable rates of unplanned patient transfer.
