Abstract

Abstract: Introduction: Point‐of‐care (POC) early infant diagnosis (EID) testing has been shown to dramatically decrease turnaround times from sample collection to caregiver result receipt and time to ART initiation for HIV‐positive infants compared to centralized laboratory testing. As governments in sub‐Saharan Africa implement POC EID technologies, we report on the feasibility and effectiveness of POC EID testing and the impact of same‐day result delivery on rapid ART initiation within national programmes across six countries. Methods: This pre‐/post‐evaluation compared centralized laboratory‐based (pre) with POC (post) EID testing in 52 facilities across Cameroon, Democratic Republic of Congo, Ethiopia, Kenya, Senegal and Zimbabwe between April 2017 and October 2019 (country‐dependent). Data were collected retrospectively from routine records at health facilities for all infants tested under two years of age. Hazard ratios and 95% confidence intervals were calculated to compare time‐to‐event outcomes, visualized with Kaplan–Meier curves, and the Somers' D test was used to compare continuous outcomes. Results: Data were collected for 2892 EID tests conducted on centralized laboratory‐based platforms and 4610 EID tests on POC devices with 127 (4%) and 192 (4%) HIV‐positive infants identified, respectively. POC EID significantly reduced the time from sample collection to caregiver result receipt (POC median: 0 days, IQR: 0 to 0 vs. centralized: 35 days, IQR: 26 to 56) and time from sample collection to ART initiation for HIV‐positive infants (POC median: 1 day, IQR: 0 to 7 vs. centralized: 39 days, IQR: 26 to 57). With POC testing, 72% of infants received results on the same day as sample collection; HIV‐positive infants with a same‐day diagnosis had six times the rate of ART initiation compared to those diagnosed one or more days after sample collection (HR: 6.39; 95% CI: 3.44 to 11.85). Conclusions: Same‐day diagnosis and treatment initiation for infants is possible with POC EID within routine government‐led and ‐supported public sector healthcare facilities in resource‐limited settings. Given that POC EID allows for rapid ART initiation, aligning to the World Health Organization's recommendation of ART initiation within seven days, its use in public sector programmes has the potential to reduce overall mortality for infants with HIV through early treatment initiation.
