Clinical, Surgical, and Sociopsychological Factors and Depression After Cardiothoracic Surgery

Background. Depression is highly prevalent in cardiac surgical patients and is associated with mortality. The objectives of the study were to evaluate depression scores longitudinally pre- and postoperatively and to examine the association between postoperative depression scores and clinical, surgical, and sociopsychological factors. Methods. Depression scores were assessed using the Center for Epidemiological Study of Depression (CES-D) in 100 cardiac surgical patients who underwent cardiac surgery preoperatively, during hospitalization, and at 2 and 6 week after discharge. Clinical, surgical, and sociopsychological predictors of depression scores were recorded. Results. The average depression scores significantly increased from preoperative levels (14.9 +/- 1.07) to during hospitalization (21.5 +/- 1.05) and decreased at both 2 weeks (15.8 +/- 1.07) and 6 weeks after discharge (14.0 +/- 1.06), as compared with scores during hospitalization (P < .001). The percentage of patients who scored CES-D > 16 increased significantly from preoperative (39%) to hospitalization (71%) and decreased gradually at 2 weeks (45%) and 6 weeks (37%) after discharge (P < .001). Significant predictors of high postoperative CES-D scores were female gender, ejection fraction < 50%, and high preoperative CES-D scores. Conclusions. High depression scores after cardiac surgery suggest that perioperative screening and management of depression after surgery are necessary and may improve outcomes of these patients who are at high risk for depression. Further understanding of the factors that contribute to high depression scores is required to facilitate clinical intervention. (C) 2021 by The Society of Thoracic Surgeons

Automated summary

This study evaluated depression scores in cardiac surgical patients before and after surgery, finding a significant increase in postoperative depression scores compared to preoperative levels. Female gender, ejection fraction < 50%, and high preoperative depression scores were identified as significant predictors of high postoperative depression scores. Further research is needed to understand the factors contributing to high depression scores and improve clinical intervention.
