Methods
From January 2020 to January 2021, 55 incarcerated men with HIV were recruited as index participants from six jail and prison facilities in Jakarta in a two‐group randomized trial comparing the outcomes of self‐tell notification (treatment as usual) versus Impart APN in increasing partner notification and HIV testing. Participants voluntarily provided names and contact information for sex and drug‐injection partners in the community with whom they had shared possible HIV exposure during the year prior to incarceration. Participants randomized to the self‐tell only condition were coached in how to notify their partners by phone, mail or during an in‐person visit within 6 weeks. Participants randomized to Impart APN could choose between self‐tell notification or anonymous APN by a two‐person team consisting of a nurse and outreach worker. We compared the proportion of partners in each group who were notified of exposure by the end of 6 weeks, subsequently tested and HIV diagnosed.
