Objective(S)To determine differences in perioperative abdominal aortic aneurysm (AAA) repair outcomes based on patient sociodemographics.DesignA retrospective analysis of patient hospitalization and discharge records.SettingAll-payer patients in nonpsychiatric hospitals in New York, Maryland, Florida, Kentucky, and California.ParticipantsA total of 92,028 patients from the State Inpatient Databases Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality from January 2007 to December 2014 (excluding California, ending December 2011) who underwent AAA repair.InterventionsData extraction and univariate and multivariate regression analysis.Measurements And Main ResultsPatients in the highest income quartile were less likely to be readmitted compared with those in the poorest income quartile at both 30 days (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.83-0.95) and 90 days (OR 0.85, 95% CI 0.81-0.91). Hospital readmissions were significantly greater for African American (OR 1.32, 95% CI 1.20-1.44) and Hispanic patients (OR 1.14, 95% CI 1.04-1.25) compared with white patients 30 days after AAA repair. These results were consistent 90 days after AAA repair. Patients insured with Medicare (OR 1.25, 95% CI 1.17-1.34) or Medicaid (OR 1.46, 95% CI 1.30-1.64) were more likely to be readmitted after both time points as compared with those with private insurance. The authors also found that patients with lower income, African American and Hispanic patients, and patients without private insurance were all significantly more likely to undergo emergency rather than elective repair.ConclusionsLower socioeconomic status is shown to be an independent risk factor for increased postoperative morbidity in AAA repair. The authors believe the present study demonstrates the importance of socioeconomic status as a factor in perioperative risk stratification.Copyright © 2019 Elsevier Inc. All rights reserved.
