Anxiety and depression as risk factors for postoperative complications and pain in lumbar spine surgery: A national database study

Abstract

Objective: To investigate the potential association between anxiety and depression and surgical outcomes in patients undergoing LSS. By analyzing data from the Nationwide Inpatient Sample (NIS) database, we aim to identify whether anxiety and depression serve as predictors for postoperative complications and pain-related symptoms. Methods: A retrospective analysis was conducted via the NIS database. Those undergoing LSS from 2010 to 2019 were divided into four groups: those with a diagnosis of anxiety, depression, both depression and anxiety, and neither depression nor anxiety. The chi-squared test, rank sum test, the Student-Newman-Keuls, least significant difference, and Bonferroni tests were used to identify differences between these groups. Logistic regression analysis was utilized to determine if anxiety and depression were predictors for postoperative complications and pain-related symptoms. Results: From 2010 to 2019, 832,099 patients undergoing LSS were identified. Patients with either anxiety or depression were associated with heavier economic burdens ($85,375, $76,840, $88,542 in the anxiety, depression, and comorbid group, respectively, p < 0.001) and prolonged hospital stay ( p < 0.001). They were identified to experience higher risks of various complications especially thrombophilia (OR = 1.82, and 1.55 in the anxiety and the depression group, respectively, p < 0.01). Multiple pain-related symptoms, but face reduced risks of inpatient mortality (OR = 0.71, 0.75, and 0.63 in the anxiety, depression, and comorbid group, respectively, p < 0.01). Conclusions: The overall morbidities of depression and anxiety were relatively high. Psychiatric comorbidities were closely correlated with the negative outcomes after LSS. The psychological health of patients receiving LSS requires necessary attention to ensure pain control and prevent complications postoperatively.
