PUR1: HEALTH STATUS OF ELDERLY DIALYSIS PATIENTS

Abstract

OBJECTIVES: The elderly comprise approximately half of new patients undergoing dialysis, an expensive, lifesaving treatment. We report the health status of 3 elderly age groups, including novel information about patients 85 years, hypothesizing that as age increases health status will decrease. METHODS: This retrospective analysis reports on 6154 patients treated by one dialysis chain (48.4% male, 61.5% white, 39.1% diabetes as primary diagnosis). Health status is reported by a single administration of the SF-36 between 10/30/90 and 10/30/00. RESULTS: Although not statistically significant at p < .01, with increasing age, there are trends to lower Physical Function and Role Physical scores. The Physical Component Score shows a statistically significant difference between groups 1 and 2. Group 3, the very elderly, are not significantly different from groups 1 or 2. Other scales show no change. CONCLUSIONS: As hypothesized, physical health of dialysis patients appears vulnerable to age. However, other domains of health status remain robust. The very elderly receiving dialysis maintain their mental health when compared to patients in the 2 younger age groups. (See table below.)
