Health-related quality of life in survivors of open ruptured abdominal aortic aneurysm repair: A matched, controlled cohort study
Received 15 February 2007; accepted 10 April 2007.
Objective
The objective of this study was to document the health-related quality of life (HRQOL) for patients who survived operative repair of a ruptured abdominal aortic aneurysm (RAAA) and to compare this with a matched group of patients who survived elective operative repair of an abdominal aortic aneurysm (EAAA).
Methods
A matched, controlled cohort study of HRQOL was used to compare patients surviving RAAA with an EAAA control group. The study was conducted at two university-affiliated vascular tertiary care referral centers. Survivors of RAAA and EAAA during an 8.5-year period were identified and followed up. The RAAA and EAAA control patients were matched for age, serum creatinine concentration, gender, and duration of follow-up since surgery. HRQOL was measured with the Medical Outcomes Study Short Form-36 Health Survey (SF-36). Scores for the EAAA and RAAA cohorts were also compared with age-corrected SF-36 population scores.
Results
Of 267 patients operated for RAAA during the study period, 130 (49%) survived to hospital discharge. Death after discharge was documented in 35 patients, leaving a potential study population of 95 RAAA survivors. Thirteen were lost to follow-up, seven refused to participate, and four patients were not able to participate. The SF-36 was completed by 71 RAAA patients (75% of surviving RAAA patients). The 71 RAAA survivors and 189 EAAA control patients were similar for seven of eight domains of the SF-36: Physical Function, Role-Physical, Bodily Pain, General Health, Vitality, Mental Health, and Role-Emotional. There was also no difference in the Physical Health Summary and Mental Health Summary scores. The social function component of the SF-36 demonstrated a statistically significant decline in the EAAA group. Both the EAAA and RAAA SF-36 individual and summary scores compared favorably with population norms that were adjusted only for age.
Conclusion
Long-term survivors of RAAA enjoy a HRQOL that does not differ significantly from EAAA survivors. Scores for both groups compare favorably with population scores adjusted only for age.
