Integrating PrEP into HIV care clinics could improve partner testing services and reinforce mutual support among couples: provider views from a PrEP implementation project in Kenya.

Introduction: Partner notification services (PNS) increase the HIV status knowledge and linkage to care and treatment. However, it is unclear if PNS can facilitate linkage of HIV-negative partners to prevention services such as pre-exposure prophylaxis (PrEP). Using qualitative methods, we explored provider perspective regarding the interaction of PrEP availability, PNS and antiretroviral treatment (ART) outcomes within a project integrating PrEP services into HIV care clinics in eight counties in western and central Kenya. Methods: From May 2017 to August 2018, data on integrated PrEP service delivery including its interaction with PNS were collected through 71 key informant in-depth interviews with healthcare providers and 24 standardized technical assistance reports summarizing implementation at the participating clinics. Thus, the perspective was from that of providers; analyses focused on emergent themes relating PNS to PrEP and ART services. Results: Providers found that PrEP integration provided an additional concrete prevention option for HIV-negative partners and created a motivation to offer PNS to persons living with HIV. PrEP availability also seemed to operate as an incentive for those living with HIV to participate in PNS, which in turn enhanced identification of potential PrEP clients and created an environment for discussing HIV transmission risk. Providers commented that initiating HIV-negative partners on PrEP enhanced mutual monitoring of health outcomes, including improved adherence to ART by partners living with HIV. Clinics noted prioritizing people living with HIV with detectable viral loads for PNS in order to identify HIV-negative partners who would benefit most from PrEP. Providers felt motivated by the apparent synergistic interaction of PNS, PrEP and ART. Conclusions: Providers felt that the integration of PrEP into HIV care clinics stimulated the provision of PNS, and PNS was used to improve the identification of potential PrEP clients. The integrated combination of PNS, PrEP and ART is synergistic and should be promoted in HIV clinics.
