Association of American Society of Anesthesiology and Modified Charlson Comorbidty Index Scores with Survival in Geriatric Patients Undergoing Thoracic Surgery

We aimed to evaluate the relationship between preoperative American Society of Anesthesiology and Modified Charlson Comorbidty Index scores and postoperative survival in geriatric patients who had undergone thoracic surgery. Methods: A total of 109 patients aged 65 years and above who had undergone thoracic surgery under elective conditions were included in this retrospective study. Results: Patients who died within the first postoperative two years had higher American Society of Anesthesiology III-IV scores (p=0.03), higher Modified Charlson Comorbidty Index scores (p=0.04), and lower hemoglobin and hematocrit values (p=0.02 and p=0.005, respectively). We found that Modified Charlson Comorbidty Index was significantly effective in predicting two-year mortality among geriatric patients (AUC = 0.648, 95% CI: 0.516-0.780, p=0.02). In the ROC analysis, the best predictive cut-off value for Modified Charlson Comorbidty Index was found to be 7 (sensitivity: 79.7%, and specificity: 44.4%).
