Association Between Age and Survival Following Major Amputation

摘要: Objectives:to determine whether age is associated with survival following major amputation and this association independent or simply reflects selection bias in level.Design materials:computer linkage of routine discharge death data on the 2759 patients undergoing Scotland between 1989 1993 for peripheral arterial disease.Methods:Cox's proportional hazards model multivariate logistic regression analysis using as outcome variable age, sex, urgency, level recent reconstructive surgery predictor variables.Results:proximal was more common older patients. Survival both (p<0.001) (p<0.001). Age an at 30 days (p<0.0001), 6 months (p<0.001), 12 (p<0.0001) 2 years postoperation.Conclusions:survival poor, only half alive years. Above-knee poorer survival, presumably due to presence severe widespread disease, undertaken commonly However, remained a after adjustment level. Higher early mortality suggest that worse prognosis elderly cannot be attributed wholly actuarial considerations.
