A Statewide, Population-Based, Time-Series Analysis of the Outcome of Ruptured Abdominal Aortic Aneurysm

Abstract

Ruptured abdominal aortic aneurysm remains a highly lethal lesion, even in the best of hands. Despite the many improvements in the care of seriously ill patients, there was no significant improvement in the survival of RAAA during this study. This suggests that early diagnosis is the best hope of survival in these patients. The study demonstrated that survival after RAAA was related most strongly to patient age at the time of the RAAA. The physician's and the hospital's experience with RAAA, the physician's background as measured by board certification, and the type of hospital at which the operation was performed (small vs. large) also may be associated with survival. These findings may have important implications for the regionalization of care and the education and credentialling of physicians. Given the lack of recent progress of improving the outcome of RAAA, aggressive efforts to treat patients before rupture are appropriate.
