Data to care (D2C) has shown promising results to support the HIV care continuum and increase retention and re-engagement in care. Several low and middle-income countries (LMIC) have started to implement case-based surveillance (CBS) systems to optimize HIV services. CBS systematically and continuously collects demographic and health event data on PLHIV from diagnosis until death. D2C takes CBS a step further by tracking PLHIV across facilities and facility networks, thus distinguishing true loss from migration and enabling the deployment of specialized interventions to re-engage patients who drop out of care. Can the data value chain be moved to truly start and end with an individual client under this new paradigm? Panelists will share key lessons learned from implementing D2C or CBS across a range of settings. The panel will discuss achievements, gaps, opportunities, and future directions with a particular focus on what is sustainable in LMIC.
