Background: In-hospital mortality rates following all types of pancreatic resections (PRs) have decreased over recent decades. Our aim was to identify predictors of in-hospital mortality following pancreatic resection.
Methods: All patients undergoing pancreatic resection were sampled from the National Inpatient Sample (NIS) in the years 2007-2012. Predictors of in-hospital mortality were identified and incorporated into a binary logistic regression model.
Results: A total of 111,568 patients underwent pancreatectomy. Annual mortality rates decreased from 4.3% in 2007 to 3.5% in 2012. Independent predictors of in-hospital mortality included age ≥75 years (vs. <65 years, OR = 2.04; 95% CI: 1.61-2.58), nonelective procedure status (OR = 1.46; 95% CI: 1.19-1.80), resection other than distal pancreatic resection (vs. Whipple, OR = 2.14; 95% CI: 1.71-2.69; other partial, OR = 2.48; 95% CI: 1.76-3.48), lower hospital volume (OR = 1.28; 95% CI: 1.09-1.49), indication for pancreatic resection other than benign diseases (vs. malignant, OR = 1.63; 95% CI: 1.25-2.15; other, OR = 2.48; 95% CI: 1.76-3.48), pulmonary complications (OR = 12.36; 95% CI: 10.11-15.17), infectious complications (OR = 2.17; 95% CI: 1.78-2.64), noninfectious wound complications and pancreatic leak (OR = 1.94; 95% CI: 1.53-2.46), and acute myocardial infarction (OR = 2.03; 95% CI: 1.32-3.06).
Discussion: Our findings identify predictors of inpatient mortality following pancreatectomy, with pulmonary complications representing the single most significant factor for increased mortality. These findings complement and expand on previously published data and, if applied to perioperative care, may enhance survival following pancreatectomy.
