Abstract
Depression, anxiety, posttraumatic stress disorder (PTSD), and substance abuse are linked to higher rates of morbidity and mortality after various surgical procedures. Comparable data in general surgery are lacking. Records from 183 consecutive patients undergoing elective general surgery procedures at a single tertiary hospital were reviewed. Patients with depression, anxiety, PTSD, and substance abuse or any combination of these at the time of surgery were classified as having "active mental illness" (AMI). Thirty-day complications, readmissions, and emergency room (ER) visits were identified. Univariate analysis was performed followed by creation of multivariate regression models. 41.5 per cent (n = 76) met criteria for the AMI group and 58.5 per cent (n = 107) were without a mental illness (WAMI). The two groups had similar incidence of medical comorbidities and similar mean values of serum albumin and creatinine. The AMI group had higher rates of readmissions (14.5 vs 3.7 %, P = 0.009) and ER (19.7 vs 8.4 %, P = 0.025) visits compared with the WAMI group. Differences in length of stay and 30-day complications did not reach statistical significance. In patients undergoing elective general surgery, depression, anxiety, PTSD, and substance abuse are associated with higher rates of readmission and ER visits. These results suggest a need for further research on the impact of specific mental illnesses on postoperative complications.
