Predictors of prolonged hospital stay in cardiac surgery

The prolonged stay after cardiac surgery can significantly decrease the quality of life. Many studies have assessed the risk factors associated with length of stay but only a few have discussed the risk factors of prolonged stay after surgery. Therefore, this study is aimed to determine the risk factors affecting long term stay in hospital after CABG and to make comparison between group for each risk factors. All the risk factors were determined by Kaplan-Meier analysis. Overall, 3096 of CABG patients were discharged within less than 14 days, whereas 332 patients required prolonged (>14days) stays. The findings from the survival analysis indeicated that patients with diabetes and wound infection stayed longer in the hospital
