Factors Associated with Nonhome Discharge After Endovascular Aneurysm Repair

ARTICLE HIGHLIGHTSType of Research: Retrospective analysis of prospectively collected data from the Vascular Quality InitiativeKey Findings: From a database of 61,792 EVAR patients, advanced age, female sex, larger aneurysm diameter, diabetes, congestive heart failure, and anemia were associated with increased odds of non-home discharge. Conversely, patients with white race, normal to obese BMI, prior smoking history, as well as those on aspirin and statins, exhibited higher odds of home discharge.Take home Message: Several pre-operative factors were found to be associated with higher odds of non-home discharge, including non-modifiable factors such as female sex and larger aortic diameter, and potentially modifiable factors such as anemia, COPD, CHF, BMI, and diabetes.ABSTRACTObjectiveThis study aims to identify preoperative factors associated with non-home discharge (NHD) after endovascular aneurysm repair (EVAR). NHD has implications for patient care, readmission, and long-term mortality; nevertheless, existing literature lacks information regarding factors associated with NHD for patients undergoing EVAR. In contrast, our study assesses preoperative factors associated with NHD for this population by utilizing national data from the Vascular Quality Initiative (VQI).MethodsWe identified adult patients who underwent elective EVAR in the VQI (2003-2022) and excluded those who were not living at home preoperatively. Multivariable logistic regression was used to identify preoperative factors associated with NHD. Kaplan-Meier methods and Cox-regression analyses were used to assess the impact of NHD on 5-year survival as a secondary outcome.Results61,792 patients were included, of which 3,155 (5.1%) had NHD. NHD patients were more likely to be older (79 [73-18] years vs. 73[67-79] years), female (33.7% vs. 18.2%; P<.001), non-white (16.0% vs. 11.7%; P<.001) and have more comorbidities. NHD patients had higher rates of postoperative complications (acute kidney injury: 11.9% vs. 2.0%; P<.001, myocardial infarction: 3.8% vs. 0.5%; P<.001, and in-hospital reintervention: 4.7% vs. 0.5%; P=.033). Multivariable analysis revealed many preoperative characteristics were associated with higher odds of NHD: most notably, age (per additional decade: OR=2.15, 95% CI:2.03-2.28; P<.001), female sex (OR=1.79, 95% CI:1.63-1.95; P<.001) and aneurysm diameter >65mm (OR=2.18, 95% CI:1.98-2.39; P<.001), along with potentially modifiable factors including: anemia, COPD, CHF, weight, and diabetes. In contrast, aspirin, statin, and ACE-inhibitor/ARB usage were associated with lower odds of NHD. NHD was associated with higher hazards of 5-year mortality, even after adjusting for confounders (40% vs. 14%, aHR=2.13, 95% CI:1.86-2.44; P<.001).ConclusionsSeveral factors were associated with higher odds of NHD following elective EVAR, including non-modifiable factors such as female sex and larger aortic diameter, and potentially modifiable factors such as anemia, COPD, CHF, BMI, and diabetes. Special attention should be given to populations with non-modifiable factors, and efforts at optimizing medical conditions with higher NHD likelihood seems appropriate to improve patient outcomes and quality of life after EVAR.
