Abstract
Comorbidities affect outcome, but there is no consensus which comorbidity instrument
is best in orthopedic surgery. We assessed whether the American Society of Anesthesiologists
Physical Status score (ASA) predicts long-term mortality after hip fracture. We followed
1635 patients for 5 to 10 years after operative treatment of hip fracture. Unadjusted
Kaplan-Meyer statistics indicated that the overall survival of the patients was 4.7
(95% confidence interval [CI], 4.5-4.9) years, but survival varied significantly between
the ASA groups. Survival for ASA 1 was 8.5 years (95% CI, 7.8-9.2); for ASA 2, it
was 5.6 years (95% CI, 5.3-5.9); for ASA 3, it was 3.5 years (95% CI, 3.2-3.7); and
for ASA 4, survival was 1.6 years (95% CI, 1.0-2.1). The ASA predicts long-term mortality
after hip fracture treatment.
