Abstract

Background: Bariatric surgery is underutilized.

Objectives: To identify factors associated with eligible patient dropout from bariatric surgery.

Setting: University hospital, United States.

Methods: Eligible candidates were identified after a multidisciplinary review committee (MRC) of all patients (n = 484) who attended a bariatric surgery informational session (BIS) at a single-center academic institution in 2015. We compared patients who underwent surgery within 2 years of BIS with those who did not (i.e., dropped out) by evaluating patient, insurance, and program-specific variables. Univariate analyses and multivariable regressions were performed to identify factors associated with patient dropout among eligible candidates.

Results: We identified 307 (63%) patients who underwent MRC. Thirty-three (11%) patients were deemed poor candidates and surgery was not recommended. Among eligible candidates, 82 (30%) dropped out from the program. Factors independently associated with eligible patient dropout included coronary artery disease (odds ratio [OR] .13 [.02-.66]; P = .014), hypertension (OR .46 [.24-.87]; P = .017), time from BIS to MRC (OR .99 [.99-.99]; P = .002), 3 months of medically supervised weight loss documentation (OR .09 [.02-.51]; P = .007), endocrinology clearance (OR .26 [.09-.76]; P = .014), hematology clearance (OR .37 [.14-.95]; P = .039), urine drug screen testing (OR .31 [.13-.72]; P = .006), additional psychological evaluation (OR .43 [.20-.93]; P = .031), and required extra sessions with the dietician (OR .39 [.17-.92]; P = .032). Thirty-three (6.8%) patients underwent surgery at another institution, and 42% of these patients lived more than 50 miles from attended BIS site.

Conclusions: Twenty-seven percent of patients did not undergo bariatric surgery at their initial site of evaluation despite being considered eligible candidates after MRC. Dropout was independently associated with patient, insurance, and program-specific variables that may represent barriers to care amenable to improvement.
