title: Changing trends of HIV-related hospitalizations: a small area analysis in Illinois, 1994-2000.
abstract: This paper describes the characteristics of HIV-related hospitalizations in Illinois and compares these to nationally available data. We used HIV-related hospitalization data abstracted from an administrative dataset maintained by state mandate. Overall, HIV-related hospitalizations decreased in Illinois between 1996 and 2000. The proportion of hospitalizations for infants also decreased. However, trend analyses indicated that both the proportion of hospitalizations involving females and the mean age of hospitalized patients increased while the proportion of hospitalizations ending in mortality and the average charge per hospitalization decreased during the observation period. Small area analyses found significant regional variations in the proportion of hospitalizations ending in in-hospital mortality, costs of a hospitalization and rate of decline in the percent of hospitalization over time. Compared to national data, HIV-related hospitalizations in Illinois were more expensive, less likely to end in mortality and less likely to involve females. These results indicate that evaluation of data at several geographic levels can provide healthcare policy makers with essential information at each level of analysis.
