Objective: To determine out-of-pocket (OOP) costs 2 years after sleeve gastrectomy (SG) or initiating Ozempic for patients with type 2 diabetes (T2D) and obesity. Background: Individuals with obesity and T2D have a variety of treatment options. The risks and benefits of these treatment options are becoming more well-documented; however, the real-world patient costs of these options are not known. Methods: Adults with body mass index of 35 kg/m2 or higher and T2D who had an SG or used Ozempic were identified in the employer-based retrospective claims database Merative (previously Truven IBM Marketscan) from 2017 to 2021. SG cohort was defined as having an SG (without filling a prescription for Ozempic), and the Ozempic cohort was defined as continuously filling a prescription for Ozempic for at least 2 years (and not having any bariatric surgery). Individuals in each cohort were 1:1 propensity matched on demographics, obesity-related comorbidities, and baseline OOP costs. in the year before treatment. OOP costs were compared in the 2 years after treatment using paired t tests. Results: A total of 302 SGs were matched to 302 Ozempic patients (mean age: 50, mean baseline body mass index: 40, 41% males). OOP health care costs were similar for the SG ($2267) and Ozempic ($2131) cohorts 1 year after the index date (difference = $136, P = 0.19). OOP health care costs were significantly lower in the SG cohort ($1155 vs $2,084, P < 0.01) 2 years after the index date. Conclusions: Within 2 years of starting treatment, OOP health care costs were significantly lower among individuals who had a SG versus those treated with Ozempic.
