Iyengar A, Goel NJ, Kelly JJ, et al. - Researchers investigated the incidence, causes, predictors and costs linked with 30-day readmission after thoracic endovascular aortic repair (TEVAR) in the National Readmissions Database from 2010 to 2014. They identified a total of 24,983 TEVARs; the average age of the patients was 65 ± 16 years; 40% were women. An intact thoracic aneurysm was the most common indication (43.5%), followed by aortic dissection (30.5%). The index admission cost nearly $63 644 ± $52 312; the average hospital stay was 11 ± 14 days; the index mortality rate was 6.7%. Thirty-day readmissions were reported for 17.4% of patients. Variation in indications for readmission was observed; the most common etiologies were cardiac (17.8%), infectious (16.0%) and pulmonary (12.1%). Multivariable analysis that the strongest predictor of readmission was the diagnosis, with a ruptured thoraco-abdominal aneurysm having the highest readmission burden. Notably, there was no predictive value of hospital volume for index hospital length of stay, costs or 30-day readmissions.
