Abstract
吹火口嘴型图片The objective of this study was to develop a prospectively applicable method for classifying comorbid conditions which might alter the risk of mortality for u in longitudinal studies. A weighted index that takes into account the number and the riousness of comorbid dia was developed in a cohort of 559 medical patients. The 1-yr mortality rates for the different scores were: "0", 12% (181); "1-2", 26% (225); "3-4", 52% (71); and "greater than or equal to 5", 85% (82). The index was tested for its ability to predict risk of death from comorbid dia in the cond cohort of 685 patients during a 10-yr follow-up. The percent of patients who died of comorbid dia for the different scores were: "0", 8% (588)

With each incread level of the comorbidity index, there were stepwi increas in the cumulative mortality attributable to comorbid dia (log rank chi 2 = 165; p less than 0.0001). In this longer follow-up, age was also a predictor of mortality (p less than 0.001). The new index performed similarly to a previous system devid by Kaplan and Feinstein. The method of classifying comorbidity provides a simple, readily applicable and valid method of estimating risk of death from comorbid dia for u in longitudinal studies. Further work in larger populations is still required to refine the approach becau the number of patients with any given condition in this study was relatively small.
