Clinical and HIV Surveillance Data to Determine Care Status for People With HIV in Washington, DC.

BACKGROUND

We examined factors related to being out of care (OOC) or reentering care after clinic transfer among people with HIV in Washington, DC using clinical and linked surveillance data from the DC Department of Health (DC Health).

METHODS

Using DC Cohort HIV care encounters and laboratory results, linked surveillance data, and chart review, we determined if participants were (1) engaged in care; (2) OOC; (3) died; (4) withdrew; (5) clinic-reported transfer; (6) surveillance-based transfer (using DC Health data); and (7) undetermined. Of the clinic-reported transfers, we used surveillance data to determine whether participants reentered care after transfer. We evaluated associations between participant characteristics, being OOC, and reentering care using logistic regression.

RESULTS

We evaluated 12,563 DC Cohort participants, 6557 (52.5%) were engaged in care, 748 (6.0%) OOC, 1893 (15.0%) clinic-reported transfers, 1692 (13.5%) surveillance-based transfers, 1418 (11.0%) died, 41 (0.3%) withdrew, and 214 (1.7%) were undetermined. Of clinic-reported transfers, 832 (44.0%) reentered care, with 80.9% achieving viral suppression (<200 copies/mL). In the adjusted analysis, females, older age, non-Hispanic Black race, longer time since HIV diagnosis, CD4 ≥ 500 cells/µL, former or never smoking, and public insurance were associated with being engaged in care. Similarly, non-Hispanic Black race, non-Hispanic White race, nonviral suppression, Ryan White clinic, former alcohol abuse, and temporary/unstable housing were associated with reentering care among the clinic-reported transfers, after adjusting for covariates.

CONCLUSIONS

Individual, clinical, and structural factors were associated with being OOC or care reentry. Targeted interventions addressing these factors may improve sustained HIV care and reduce transmission.
