abstract

  • OBJECTIVE: To characterize the association between preoperative psychological distress and postoperative complications at 30 days and mortality at 1 year in a non-cardiac surgery sample. METHOD: Data were taken from a subsample of the VISION cohort study (n = 997; 2011-2012). Participants were scheduled to undergo major non-cardiac surgery under general or regional anesthesia. Participants self-reported past 30-day psychological distress on the day of surgery using the Kessler-6 (K6) Scale. Complications were assessed via interviews and/or chart reviews. Multivariable logistic regressions characterized the relationship between preoperative psychological distress and postoperative complications. Models were fitted for sociodemographics, surgery type, preoperative medical morbidity, and smoking. RESULTS: Among participants with a completed K6 (n = 938), 7.9 % experienced mortality within 1 year. After controlling for age, ethnicity, sex, surgery type, preoperative medical morbidity, and smoking, higher levels of preoperative psychological distress were associated with 30 day complications such as myocardial infarction, non-fatal cardiac arrest, leg/arm deep vein thrombosis/ pulmonary embolism, new acute renal failure, pneumonia, and congestive heart failure (AOR3 (3rd model), 1.12, [95 % CI, 1.02-1.22, p < 0.05]) and 1-year mortality (AOR3, 1.09, [95 % CI, 1.02-1.18, p < 0.05]). Sensitivity analyses demonstrate that the latter association was being driven by symptoms of depression (AOR3, 1.17 [95 % CI 1.04-1.33, p < 0.05]) but not anxiety (AOR2, 0.94 [95 % CI, 0.61-1.62, p > 0.05]). CONCLUSION: Elevated preoperative distress increased the risk of 30-day complications and mortality at 1 year. These results underscore the need for future research to examine if supporting patients' mental health during the perioperative period can mitigate risk. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov, no. NCT00512109 (main VISION study).
