Severity index scores xscorrelate with survival of AIDS patients

Abstract

A major concern of hospices treating AIDS patients is survival prognosis. Patients are eligible for government hospice benefits only if they are in the last six months of life, but for AIDS patients who present at different disease stages, it is often difficult to predict survival. We have tested an index of AIDS severity developed by Alemi et al. (1991, Interfaces, 21(3), 105) for its ability to predict survival in hospice-AIDS patients. Using retrospective analysis of medical records, a severity index (SI) score was determined for 26 AIDS patients who were admitted at different disease stages to a South Florida hospice. The length of stay for each patient was also recorded. The patients fell clearly into two groups, those with stays of six months or less and those with stays of more than six months. The mean SI scores of the two groups were .9188 and. 7845, respectively. These scores were significantly different at the p=.005 level. In this preliminary study, the severity score correlated well with survival prognosis. Based on these results, it appears that the severity index may have great utility in predicting survival for AIDS patients seeking hospice admission.
