Background: To improve the HIV continuum of care, a team of field service interventionists (State Bridge Counselors, SBC) was developed through a state public health system and provided brief (1-2) contacts for linkage of newly diagnosed persons with HIV and reengagement of persons living with HIV (PLWH) who were not in care., Setting: North Carolina, United States., Methods: Service data from January 2013 to June 2015 were analyzed to determine characteristics of clients referred to SBCs, proportions linked or reengaged in care, and/or achieved viral load suppression (VLs). We evaluated associations between client characteristics and outcomes using multivariable analyses and estimated odds ratios (OR) with 95% confidence intervals (CI)., Results: SBCs provided linkage services to 299 newly diagnosed individuals and reengagement services to 606 PLWH throughout North Carolina. Among persons who received linkage services, 189 (63%) had evidence of care within 90 days of referral and 205 (69%) had VLs within a year. Among PLWH who received reengagement services, 278 (46%) had care within 90 days and 308 (51%) had VLs within a year. Persons aged 30-39 years (OR, 2.1; 95% CI, 1.1 to 3.9) and 40-49 years had an increased likelihood (OR, 2.4; 95% CI, 1.1 to 5.2) of linkage within 90 days compared with persons aged 18-29 years. Non-white PLWH had an increased OR of 1.7; (95% CI, 1.2 to 2.5) of reengagement compared with whites., Conclusions: Our SBC program successfully implemented a "low-touch" approach to provision of linkage and reengagement services, demonstrating that public health resources can be used to address the HIV care continuum on a statewide level.

The HIV care continuum is a critical framework for situational awareness of the HIV epidemic; yet challenges to accurate enumeration of continuum components hamper continuum estimation in practice. We describe local surveillance-based estimation of the HIV continuum in the United States, reviewing common practices as recommended by the Centers for Disease Control and Prevention. Furthermore, we review some challenges and biases likely to threaten existing continuum estimates. Current estimates rely heavily on the use of CD4 cell count and HIV viral load laboratory results reported to surveillance programs as a proxy for receipt of HIV-related outpatient care. As such, continuum estimates are susceptible to bias because of incomplete laboratory reporting and imperfect sensitivity and specificity of laboratory tests as a proxy for routine HIV care. Migration of HIV-infected persons between jurisdictions also threatens the validity of continuum estimates. Data triangulation may improve but not fully alleviate biases.
