Expanded HIV Testing and Linkage to Care: Conventional vs. Point-of-Care Testing and Assignment of Patient Notification and Linkage to Care to an HIV Care Program

Abstract

Objective. The University of Chicago Medicine (UCM) led the Expanded Testing and Linkage to Care (X-TLC) program for disproportionately affected populations on the South Side of Chicago. The X-TLC program aimed to expand routine HIV testing to high-prevalence communities with disproportionately affected populations (i.e., minority men and women, men who have sex with men, and intravenous drug users) according to CDC guidelines at multiple clinical sites. Methods. The X-TLC program used standard blood-based laboratory testing vs. point-of-care rapid testing or rapid laboratory testing with point-of-care results notification. Site coordinators and the linkage-to-care coordinator at UCM oversaw testing, test notification, and linkage to care. Results. From February 1, 2011, through December 31, 2013, the X-TLC program completed 75,345 HIV tests on 67,153 unique patients. Of the total tests, 48,044 (63.8%) were performed on patients who self-identified as African American and 6,606 (8.8%) were performed on patients who self-identified as Hispanic. Of the 67,153 patients tested, 395 (0.6%) tested positive and 176 (0.3%) were previously unaware of their HIV-positive status. Seroprevalence was even higher for EDs, where 127 of 12,957 patients tested positive for HIV (1.0% seroprevalence), than for other patient care sites, including for new diagnoses, where 50 of 12,957 patients tested positive for HIV (0.4% seroprevalence). Of the 176 newly diagnosed patients, 166 of 173 (96.0%) patients who were still alive when testing was complete received their test results, and 148 of the 166 patients who were eligible for care (89.0%) were linked to care. Patients linked to X-TLC physicians did well with respect to the continuum of care: 77 of 123 (62.6%) patients achieved HIV viral load of <200 copies/milliliter. Conclusion. Lead organizations such as UCM were able to assist and oversee HIV screening and linkage to care for HIV patients diagnosed at community sites. HIV screening and linkage to care can be accomplished by incorporating standard testing for HIV into routine medical care.
