The Cascade of Care From Routine Point-of-Care HIV Testing at Birth: Results From an 18-Months Pilot Program in Eswatini.

Abstract

Background:HIV testing at birth may improve early treatment, but concerns remain about feasibility and retention of infants in care. In 2017, point-of-care (POC) HIV birth testing was introduced into routine care at 3 high-volume maternity health facilities in Eswatini.Methods:POC birth testing was offered to HIV-exposed infants (HEI) born at, or presenting to, 3 maternities within 3 days of birth. Data were collected from a project-specific EID test request form and routine registers on all tests conducted from August 1, 2017 to November 30, 2018, including retesting at 6–8 weeks for infants testing negative at birth and six-month retention in HIV care and viral load suppression among infants testing HIV-positive at birth.Results:Of 4322 eligible HEI, 3311 (76.6%) were tested. Twenty-six HIV-infected infants were identified (positivity rate 0.8%) and 25 initiated on antiretroviral therapy (ART) (96.1%). The median time from sample collection to ART initiation was 20.50 days (IQR 14–45). Twenty-one (84%) ART-initiated infants were on ART at 6 months after initiation. Nineteen infants (90.5%) had viral load test information at 6 months and 16 (84.2%) were virally suppressed. Of 3126 HEI testing negative at birth, 3004 (96.1%) were linked to laboratory databases and 2744 (91.3%) were retested at 6–8 weeks, with 9 (0.3%) additional infants testing HIV-positive.Conclusions:Uptake of POC birth testing was high in Eswatini with low HIV positivity. Almost all infants identified HIV-positive at birth were initiated on ART, with high retention in care and viral suppression. Birth testing did not seem to significantly reduce subsequent 6–8-week testing.
