Qualitative Insights on Client and Provider Barriers and Facilitators to Using a Novel Online HIV Pre- and Post-Exposure Delivery Model in Kenya.

introductionOnline delivery of HIV pre- and post-exposure prophylaxis (PrEP and PEP) could address persistent access barriers, yet implementation across Africa remains limited. The ePrEP Kenya Pilot (NCT05377138) integrated PrEP and PEP services into an existing e-pharmacy platform and identified client- and provider-level barriers and facilitators to use.

methodsIn the pilot, clinicians screened adults (age 18+) in Nairobi and Mombasa Counties for PrEP and PEP eligibility via telehealth; pharmaceutical technologists courier-delivered HIV testing services (including self-testing) and dispensed PrEP or PEP to eligible clients who paid 150-250 KES (∼$1-2 USD) for HIV testing, ≤149 KES (∼$1 USD) for courier delivery and nothing for telehealth consultation or PrEP/PEP drugs. We conducted monthly check-in calls with providers and, near study endline, in-depth interviews (IDIs) with purposively sampled clients and all providers. We analysed verbatim call transcripts and IDIs inductively, then mapped identified barriers and facilitators to the Consolidated Framework for Implementation Research (CFIR).

resultsFrom February to November 2023, we conducted 10 check-in calls and interviewed 30 clients (10 PEP, 10 PrEP with 1+ refill, 10 PrEP with no refills) and 10 providers (4 clinicians, 6 pharm techs). Clients had a median age of 27 years (IQR 25-30) and providers 28 years (IQR 27-31); 53% (16/30) of clients and 30% (3/10) of providers were female. In the Outer Setting CFIR domain, providers identified motorcycle manoeuvrability as a delivery facilitator but noted that traffic, poor road infrastructure, bad weather and personal safety concerns posed challenges. In the Inner Setting domain, providers identified information-sharing practices and collegiality as facilitators. In the Individuals domain, clients' capability, opportunity and motivation to use online PrEP/PEP services was reportedly facilitated by app-guided HIV self-testing, broad delivery zones and enhanced privacy, but hindered by low awareness of these services, limited access to internet-enabled devices, data security concerns and uncertainties around couriers' pharmacy credentials. Recommendations included reducing client costs, expanding delivery coverage and hours, and offering alternative delivery options (e.g. medication pick-up lockers).

conclusionsOnline PrEP and PEP delivery is a promising differentiated service model, especially if partially subsidized by third-party payers. Implementation success will require model adaptations that address logistical, infrastructural and awareness barriers.
