Abstract
BACKGROUND: To promote use of lifestyle, pharmacologic, and surgical weight management options for adults with body mass index (BMI) ≥35 kg/m(2) and type 2 diabetes (T2D), this project implements and evaluates a weight loss clinical decision support (WL-CDS) intervention that provides patient-specific estimates of the risks and benefits of evidence-based obesity management options to primary care clinicians (PCCs) and patients at primary care clinical encounters. METHODS: We randomize 38 primary care clinics to either (a) usual care (UC), or (b) the WL- CDS intervention that provides patients and PCCs recommendations for lifestyle changes and patient-specific obesity management options and estimates of benefits and risks of weight loss medications, or metabolic bariatric surgery (MBS) when indicated. PRIMARY ENDPOINTS: Outcomes assessed at 18-months after a patient-specific index date are (a) referral of eligible patients for MBS evaluation; (b) initiation or active management of FDA-approved medications for weight loss; and (c) weight trajectory. Outcomes measured within 1 month of index date are patient-reported (d) shared decision making about weight loss options, and (e) intention to engage in weight loss. CONCLUSION: This study will deepen our understanding of how patients and PCCs use WL-CDS generated information to inform selection of obesity care options for adults with T2D and BMI ≥35 kg/m(2).
