OBJECTIVE: This study examines the frequency of inpatient hospitalization, the number of inpatient days, and factors associated with inpatient utilization in a multistate HIV cohort between 2002 and 2007.

DESIGN: A prospective cohort study of HIV-infected adults in care at 11 US HIV primary and specialty care sites located in different geographic regions.

METHODS: Demographic, clinical, and resource utilization data were collected from medical records for the years 2002-2007. Rates of resource use were calculated for number of hospital admissions, total inpatient days, and mean length of stay per admission.

RESULTS: Annual inpatient hospitalization rates significantly decreased from 35 to 27 per 100 persons from 2002 to 2007. The number of inpatient days per year significantly decreased over time, whereas mean length of stay per admission was stable. Women, patients 50 years or older, blacks, injection drug users, and patients without private insurance had higher hospitalization rates than their counterparts. Admission rates were lower for patients with high CD4 counts and low HIV-1 RNA levels.

CONCLUSIONS: Inpatient hospitalization rates and number of inpatient days decreased for HIV patients in this multistate cohort between 2002 and 2007. Sociodemographic disparities in inpatient utilization persist.
