AimsThe aim of this study was to identify risk factors associated with unplanned readmissions after hepatectomies.MethodsPatients who underwent hepatectomies between January and December of 2011 were identified using the ACS-NSQIP database. A multivariate logistic regression analysis was performed to determine predictors of unplanned readmissions related to the procedure within 30 days.ResultsUnplanned readmissions occurred in 10.5 % of all patients who received a hepatectomy. On multivariate analysis, transfusion within 72 h after surgery (odds ratio [OR] 1.74, p < 0.001), complexity of procedure (extended, OR 1.84, p = 0.004; right hepatectomy, OR 1.66, p = 0.003), and longer operative time (>median 320 min, OR 2.43, p < 0.001) were independent perioperative predictors of unplanned readmissions. Independent preoperative risk factors included elevated alkaline phosphatase (OR 1.45, p = 0.017), bleeding disorders (OR 1.72, p = 0.051), and lower albumin levels (OR 1.30, p = 0.036).ConclusionTransfusion, complexity of procedure, and duration of operation were the strongest predictors of unplanned readmissions after liver resection.
