Objective: The aim of this study was to quantify the effects of psychiatric disorders on major surgery outcomes and care resource use. Methods: This study adopted a retrospective cohort study design. The samples consisted of hospital stays. Subjects were patients who had undergone major surgery. We used multilevel regression analysis to quantify the influence of psychiatric disorders on major surgery outcomes and care resource use. Results: The total number of hospital stays included in the study was 5569, of which 250 were patients with psychiatric disorders. Compared with those without psychiatric disorders, those with schizophrenia had a significantly higher risk of complications, and those with neurotic disorder tended to have fewer complications. Total cost was significantly higher for those with schizophrenia and mood disorder and significantly lower in those with neurotic disorder. Lengths of stay were significantly longer for those with schizophrenia and mood disorder but not for those with neurotic disorder. Post-surgical mortality was equivalent among those with any psychiatric disorder and among those without a psychiatric disorder. Conclusion: The study revealed that surgical outcomes and care resource use are differentiated by psychiatric disorders.
