Implementing open data kit integrating barcode-based client identification in HIV testing and linkage to care: A user-centered design

mHealth has improved HIV interventions worldwide. Electronic data collection has made it possible to monitor HIV in near real-time. However, the pandemic in low and middle-income countries seem to be evolving in a manner leading many to believe the Sustainable Development Goal 3.3 goal of eliminating HIV by 2030 may not be achieved. The use of paper-based health records and lack of universal client unique identification may be contributing to this trend. We aimed to evaluate how data collection integrating barcode identifiers could improve HIV care. A user-centred design (UCD) approach guided the customization of open data kit integrating barcodes. By February 2021, 42,569 females tested for HIV, 2,776 (6.5%) testing positive. Using barcode identifiers, 7,483 of their male partners and 4,652 female partners of their male partners were traced and tested. Over 90% of HIV clients had achieved viral suppression during their 12-month visit. Barcode identifiers in HIV care show great potential for improving testing and treatment adherence. A UCD approach is needed in development of effective interventions.
