Barriers to bariatric surgery: Factors influencing progression to bariatric surgery in a U.S. metropolitan area.

Background: Bariatric surgery is an effective and durable treatment for obesity. However, the number of patients that progress to bariatric surgery after initial evaluation remains low.

Objectives: The purpose of this study was to identify factors influencing a qualified patient's successful progression to surgery in a U.S. metropolitan area.

Setting: Academic, university hospital.

Methods: A single-institution retrospective chart review was performed from 2003 to 2016. Patient demographics and follow-up data were compared between those who did and did not progress to surgery. A follow-up telephone survey was performed for patients who failed to progress. Univariate analyses were performed and statistically significant variables of interest were analyzed using a multivariable logistic regression model.

Results: A total of 1102 patients were identified as eligible bariatric surgery candidates. Four hundred ninety-eight (45%) patients progressed to surgery and 604 (55%) did not. Multivariable analysis showed that patients who did not progress were more likely male (odds ratio [OR] 2.2 confidence interval [CI]: 1.2-4.2, P < .05), smokers (OR 2.4 CI: 1.1-5.4, P < .05), attended more nutrition appointments (OR 2.1 CI: 1.5-2.8, P < .0001), attended less total preoperative appointments (OR .41 CI: .31-.55, P < .0001), and resided in-state compared with out of state (OR .39 CI: .22-.68, P < .05). The top 3 patient self-reported factors influencing nonprogression were fear of complication, financial hardship, and insurance coverage.

Conclusions: Multiple patient factors and the self-reported factors of fear of complication and financial hardship influenced progression to bariatric surgery in a U.S. metropolitan population. Bariatric surgeons and centers should consider and address these factors when assessing patients.
