title: Geographic variation in the management and outcome of patients with AIDS-related Pneumocystis carinii pneumonia.
abstract: Pneumocystis carinii pneumonia (PCP) is one of the most common reasons for the hospitalization of AIDS patients; however, geographic differences in PCP management have not been evaluated previously. Therefore, we abstracted data on socioeconomic characteristics, prior HIV care, severity of illness, timeliness and intensity of in-hospital care, duration of hospitalization, and survival from 1547 randomly selected medical records of patients hospitalized with AIDS-related PCP between 1987 and 1990 at 82 hospitals in Chicago, Los Angeles, Miami, New York City, and Raleigh-Durham, North Carolina. Multivariate regression models were used to assess factors associated with longer hospital stays and increased inpatient mortality. Our results showed that in-hospital mortality ranged from 15% to 27%, bronchoscopy rates from 53% to 70%, and mean length of stay from 14 days to 23 days. Geographic variations in mortality were accounted for by differences in severity of illness at admission, insurance status, and in-hospital patient management. However, significant regional variations in hospital length of stay persisted, even after adjusting for patient demographics, severity of illness, and use of diagnostic and therapeutic care resources.
