Association Between Diabetes Mellitus and Postoperative Length of Hospital Stay in Adults Surgically Treated for Aortic Dissection in the US

Abstract

Introduction and Objective. Diabetes has been demonstrated in the literature to be a known protective factor for aortic dissection and aneurysm with limited studies evaluating the relationship between diabetes and aortic dissection and aneurysm prognosis. The aim of this study was to explore the association between patients with diabetes and postoperative length of hospital stay in patients surgically treated for aortic dissection and aneurysm. Methods. This non-concurrent cohort study consisted of 1287 patients surgically treated for aortic dissection and aneurysm from the 2011-2016 National Surgery Quality Improvement Program (NSQIP). Inclusion criteria were age 55-80 and surgically treated for aortic dissection/aneurysm repair. Length of Hospital Stay (LHS) was dichotomized into a lower 75th percentile and upper 25th percentile (upper quartile considered greater than 12 days). Age, gender, race, smoking status, smoking history, hypertension, and BMI were used as covariates. Unadjusted and adjusted logistic regression analysis were applied to calculate an odds ratio (OR) and their corresponding 95% confidence intervals (CI). Results. Of the 1287 patients, 12% had diabetes. No statistically significant association was found between having diabetes and length of hospital stay following the repair of aortic dissection/aneurysm (OR 1.0; 95% CI 0.6-1.5). However, white race was associated with an increased odds for longer LHS compared with African Americans undergoing surgical treatment for aortic dissection/aneurysm repair (OR 1.9; 95% CI 1.4-2.6). Conclusions-Implications. Diabetes had no significant association with LHS in surgically treated patients undergoing aortic dissection/aneurysm repair. Further studies evaluating the relationship between race and postoperative morbidity should be considered.
