1987 to 1991 cost and utilization of Class IV HIV patients.
The 1987 to 1991 direct medical costs and service utilization of Class IV Human Immunodeficiency Virus (HIV) patients cared for at a Group Health Cooperative of Puget Sound (GHC) are described and compared across four time periods: 1987-'88, 1989, 1990, and 1991. Cost and utilization information for an age- and sex-matched control group of GHC enrollees not having Class IV HIV conditions are also compared to those of the Class IV HIV group. Data are presented on pharmacy, inpatient care, outpatient visits by physician specialty, laboratory, radiology, home health/hospice and other costs. The costs of the Class IV HIV population are, on average, 20 times those of the control group. The percent distribution of the control group's costs did not experience much change from 1989 to 1991. Conversely, the Class IV HIV group experienced a shift in costs from the inpatient to outpatient setting from 1987-'88 to 1989. This shift was temporary, as the locus of care shifted back to the inpatient setting over the following 2 years. Anecdotal evidence suggests that antiretroviral treatment may have led to a period in which patients required less intensive settings to manage their illness. Inpatient costs may have increased as the initial benefit of zidovudine treatment began to wane. The Class IV HIV population had greater percent of total expenses in pharmacy, laboratory, radiology, and home health/hospice services, and lower percent of total expenses in outpatient primary and specialty care than the control group.
