Patterns of engagement in care by HIV-infected adults: South Carolina, 2004-2006

Identify factors associated with HIV care utilization in South Carolina.

Cross-sectional analysis of South Carolina nonpregnant HIV-infected individuals (N = 13,042) for the period 1 January 2004 to 31 December 2006.

Reporting of HIV laboratory markers is legally mandated in South Carolina. Individuals with reported viral load tests or CD4 cell counts during a calendar year were defined as 'in HIV-medical care' that year. Care utilization categories were in care, care all 3 years; not-in-care (NIC), no care received; and transitional care, during some but not all years. Multinomial logistic regression using generalized logits was used to estimate relationships between care utilization and predictor variables.

Five thousand, two hundred and seventeen (40.0%) of South Carolina HIV-infected adults were NIC and 3300 (25.3%) were in transitional care during 2004-2006. Although a larger number of black than white HIV-infected adults were NIC, adjusted odds for NIC status were lower among blacks than whites [adjusted odds ratio (AOR), 0.82; 95% confidence interval 0.74, 0.92)]. Women had lower odds of being NIC than men (AOR, 0.66; 95% confidence interval 0.58, 0.74). Compared with individuals 55 years or older, individuals who were 25-34 years old were most likely to demonstrate both the NIC (AOR, 1.85; 95% confidence interval 1.29, 2.65) and transitional (AOR, 1.85; 95% confidence interval 1.31, 2.62) care patterns.

Large proportions of the South Carolina HIV-infected adult population are not consistently accessing HIV-medical care. Targeted programs are needed to improve engagement for HIV-infected adults most likely to transition or not be in care.
