Medical Versus Surgical ICU Obese Patient Outcome: A Propensity-Matched Analysis to Resolve Clinical Trial Controversies

Objectives: To determine the short- and long-term mortality of obese ICU patients following medical as opposed to surgical admission and the relation between obesity and mortality. Design: Retrospective analysis of prospectively collected data, using a propensity score–matched analysis of patients with medical or surgical admission. Setting: One French mixed medical-surgical ICU. Patients: Critically ill obese patients (body mass index ≥ 30 kg/m2) and nonobese patients admitted during a 14-year period. Interventions: None. Measurements and Main Results: Seven-hundred ninety-one obese patients and 4,644 nonobese patients were included, 338 (43%) and 2,367 (51%) medical and 453 (57%) and 2,277 (49%) surgical obese and nonobese patients, respectively. Mortality was significantly higher in medical than in surgical obese patients in ICU (25% vs 12%; p
