Background. Patients with mental health disorders have worse medical outcomes and experience excess mortality compared with those without a mental health comorbidity. This study aimed to evaluate the relationship between mental health comorbidities and surgical outcomes.
Methods. This retrospective cohort study used the National Inpatient Sample (2009-2011) to select patients who underwent one of the 4 most common general surgery procedures (cholecystectomy and common duct exploration, colorectal resection, excision and lysis of peritoneal adhesions, and appendectomy). Patients with a concurrent mental health diagnosis were identified. Multivariable logistic regression examined outcomes, including prolonged length of stay, in-hospital mortality, and postoperative complications.
Results. Of the 579,851 patients included, 38,702 patients (6.7%) had a mental health diagnosis. Mood disorders were most prevalent (58.7%), followed by substance abuse (23.8%). After adjustment for confounders, including sex, race, number of comorbidities, admission status, open operations, insurance, and income quartile, we found that having a mental health diagnosis conferred a 40% greater odds of including prolonged length of stay (OR 1.41, P<.001) and increased odds of any complication (OR 1.18, P<.001). Odds of death were slightly less in the mental health diagnosis cohort.
Conclusions. General surgery patients with comorbid mental disease experience a greater incidence of postoperative complications and longer hospitalizations. Recognizing these disparate outcomes is the first step in understanding how to optimize care for this frequently marginalized population.
