BACKGROUND: Serious mental illness (SMI), defined as a mental disorder causing functional impairment, affects 9.8 million Americans. SMI correlates with earlier onset, more extensive cardiac disease, and reduced life expectancy by 25 years. The impact of SMI on patients undergoing cardiac surgery has not been extensively studied. We hypothesized that patients with SMI have worse cardiac surgery outcomes. METHODS: Using our institution's Society of Thoracic Surgeons database of 16,781 cardiac operations (2002-2017), a total of 1445 (8.7%) patients with SMI were identified and stratified into anxiety, mood disorders, and psychosis. The risk-adjusted impact on morbidity and mortality were evaluated using multivariable regression. RESULTS: Patients with SMI were more often female patients, were younger, and had more comorbid disease. SMI patients were more likely to have had previous cardiac surgery and require urgent or emergent procedures (both P < .05). Among specific SMI diagnoses, patients with psychosis had worse outcomes compared with the general population, with higher operative mortality (9.1% vs 4.2%; P = .001), major morbidity (30.4% vs 15.8%; P < .0001), and cost ($50,211 vs $38,820; P < .001). After multivariable risk adjustment, SMI and psychosis remained independently associated with composite mortality and major morbidity (odds ratio, 1.21; P = .012; and odds ratio, 1.68; P = .003, respectively). CONCLUSIONS: SMI is independently associated with morbidity and mortality after cardiac surgery. SMI patients, especially the subset with psychosis, are complicated, high-risk, and resource-consuming. Refined strategies to reduce postoperative complications and improve care coordination are necessary in this population.
