AbstractWe assessed the impact on patient outcomes of comorbidities and type of aneurysm repair, open vs. endovascular aortic repair (EVAR). Functional health status was measured prospectively using the Short Form 36 (SF-36) Health Survey. Length of stay (LOS) and need for postdischarge resources (nursing and rehabilitation) were compared between groups. We reviewed the records of 218 patients (126 open, 92 EVAR) who underwent intervention between 1998 and 2003. The SF-36 was completed preoperatively and at intervals ranging from 2 weeks to 1 year after intervention. To identify factors impacting outcome, univariate and multivariate analyses were performed. Overall mortality was 1.9%: 3.2% for open repair and 0% for EVAR (p = 0.13). Physical and mental health were higher during the 3 months following EVAR compared with open repair: physical function (PF) (65.2 +/- 4.1 vs. 54.0 +/- 4.1), vitality (VT) (55.5 +/- 2.5 vs. 44.9 +/- 3.4), and emotional role (ER) (74.9 +/- 5.0 vs. 51.4 +/- 6.7) (analysis of variance p < 0.05). Women following EVAR had decreased physical summary scores (PSS) (34.8 +/- 2.5 vs. 40.4 +/- 1.1, p < 0.05) compared with men postprocedure despite no difference preoperatively. Congestive heart failure (CHF) was an independent factor that negatively impacted PF, body pain (BP), and PSS. EVAR was associated with improved VT and ER. Differences among open repair and EVAR diminished over time. LOS (in days) was greater for open vs. EVAR (9.2 +/- 0.78 vs. 2.0 +/- 0.17) and in women following both open (11.8 +/- 1.5 vs. 8.0 +/- 0.9) and EVAR (3.2 +/- 0.9 vs. 1.8 +/- 0.1) procedures (p < 0.05). Factors that adversely affected LOS were open repair, age, renal insufficiency, pulmonary disease, CHF, and female gender. Following EVAR, patients were less likely to require home care or transfer to a rehabilitation facility than after open repair (14.1 vs. 36.0%, p < 0.05). Women were significantly more likely to require postdischarge care after open repair (48.7 vs. 30.1%) and EVAR (41.7 vs. 10.0%) (p < 0.05). Logistic regression identified female gender, open repair, advanced age, and pulmonary disease as independent predictors of need for postdischarge care. Those patients undergoing abdominal aortic aneurysm (AAA) repair by open technique (compared to EVAR) had significantly impaired functional health with regard to PF, VT, and ER in the first 3 months after surgery. CHF and hypertension also significantly impaired individual functional health scores. Of significance was that female gender was associated with increased LOS and increased utilization of postdischarge nursing and rehabilitation resources following both open and endovascular surgery for AAA.
