    Health Worker Perspectives on Barriers and Facilitators of Assisted Partner Notification for HIV for Refugees and Ugandan Nationals: A Mixed Methods Study in West Nile Uganda
    (AIDS and Behavior, 2021) Klabbers, Robin E.; Muwonge, Timothy R.; Ayikobua, Emmanuel; Izizinga, Diego; Bassett, Ingrid V.; Kambugu, Andrew; Tsai, Alexander C.; Ravicz, Miranda; Klabbers, Gonnie; O’Laughlin, Kelli N.
    Assisted partner notification (APN) is recommended by the World Health Organization to notify sexual partners of HIV exposure. Since 2018, APN has been offered in Uganda to Ugandan nationals and refugees. Distinct challenges faced by individuals in refugee settlements may influence APN utilization and effectiveness. To explore APN barriers and facilitators, we extracted index client and sexual partner data from APN registers at 11 health centers providing care to refugees and Ugandan nationals in West Nile Uganda and conducted qualitative interviews with health workers (N = 32). Since APN started, 882 index clients participated in APN identifying 1126 sexual partners. Following notification, 95% (1025/1126) of partners tested for HIV; 22% (230/1025) were diagnosed with HIV with 14% (139/1025) of tested partners newly diagnosed. Fear of stigma and disclosure-related violence limit APN utilization and effectiveness. Prospective research involving index clients and sexual partners is needed to facilitate safe APN optimization in refugee settlements.

    Understanding early implementation of pre-exposure prophylaxis for HIV prevention in public health facilities in Uganda using the Consolidated Framework for Implementation Research
    (Clinics, 2019) Ortblad, Katrina; Brown, Charles; Muwonge, Timothy R.; Scoville, Caitlin; Izizinga, Diego; Namanda, Sylvia; Nambi, Florence; Nakabugo, Lylianne; Mujugira, Andrew; Heffron, Renee
    In sub-Saharan Africa, a number of countries are starting to deliver oral preexposure prophylaxis (PrEP) for HIV prevention in public health facilities. • We are conducting a stepped-wedge cluster-randomized trial in 12 health facilities in Kampala & Wakiso, Uganda to launch delivery of a PrEP program within HIV clinics targeting HIV-negative members of HIV serodiscordant couples and determine the impact of the PrEP program on HIV viral suppression in partners living with HIV (ClinicalTrials.gov)

    Understanding the role of interpersonal violence in assisted partner notification for HIV: a mixed-methods study in refugee settlements in West Nile Uganda
    (Journal of global health, 2020) Klabbers, Robin E.; Muwonge, Timothy R.; Ayikobua, Emmanuel; Izizinga, Diego; Bassett, Ingrid V.; Kambugu, Andrew; Tsai, Alexander C.; Ravicz, Miranda; Klabbers, Gonnie; O’Laughlin, Kelli N
    Assisted partner notification (APN) for HIV was introduced in refugee settlements in West Nile Uganda in 2018 to facilitate testing of sexual partners. While APN is an effective strategy recommended by the World Health Organization, its safety has not been evaluated in a refugee settlement context in which participants have high prior exposure to interpersonal violence. The extent to which interpersonal violence influences APN utilization and the frequency with which post-APN interpersonal violence occurs remains unknown. Methods To explore the relationship between APN and interpersonal violence, a cross-sectional mixed-methods study was conducted at 11 health centers in or near refugee settlements serving refugee and national populations in West Nile Uganda. Routinely collected index client and sexual partner data were extracted from APN registers and semi-structured interviews were conducted with health workers. Results Through APN, 1126 partners of 882 distinct index clients were identified. For 8% (75/958) of partners, index clients reported a history of intimate partner violence (IPV). For 20% (226/1126) of partners, index clients were screened for post-APN IPV; 8 cases were reported of which 88% (7/8) concerned partners with whom index clients reported prior history of IPV. In qualitative interviews (N = 32), health workers reported HIV disclosure-related physical, sexual and psychological violence and deprivation or neglect. Incidents of disclosure-related violence against health workers and dependents of index clients were also reported. Fear of disclosure-related violence was identified as a major barrier to APN that prevents index clients from listing sexual partners. Conclusions Incidents of interpersonal violence have been reported following HIV-disclosure and fear of interpersonal violence strongly influences APN participation. Addressing HIV perception and stigma may contribute to APN uptake and program safety. Prospective research on interpersonal violence involving index clients and sexual partners in refugee settlements is needed to facilitate safe engagement in APN for this vulnerable population.
