BACKGROUND: Veterans are disproportionately affected by housing insecurity (HI), which can lead to adverse health outcomes and reduced life expectancy. We sought to examine the impact of HI on the outcomes of veterans who underwent abdominal aortic aneurysm (AAA) repair at our regional Veterans Affairs medical center. METHODS: Retrospective chart review was performed on patients who underwent AAA repair at our institution between January 1, 2000, and December 31, 2020. We examined medical history, procedure details, hospitalization course, and postoperative outcomes. Primary endpoints were a 30-day mortality and median survival. Secondary endpoints were hospital length of stay, readmission rate, and perioperative complications. Hypothesis testing was performed with t-test and chi-squared analysis. Survival analysis was conducted using Kaplan-Meier estimation. RESULTS: Of the 314 veterans that underwent AAA repair (mean age of 71.4 ± 7.8 years, 99.7% male) over the 21-year period, we identified 39 (12.4%) patients with a history of HI. The HI was associated with a positive smoking history (100% vs. 88.0%, P  =  0.022), lower rate of hypertension diagnosis (69.2% vs. 84.0%, P  =  0.024), and increased rate of surgical site infections (SSI) (10.3% vs. 1.8%, P  =  0.016). The median postoperative survival was lower in the HI group (7.6 years [CI 6.0-11.2] vs. 8.9 [CI 6.9-10.3]). CONCLUSIONS: HI was associated with reduced median postoperative survival, greater readmission rate, and increased risk of SSI following AAA repair.
