BackgroundDespite being the primary setting for HIV prevention among men who have sex with men (MSM) since the start of the epidemic, community-based organizations (CBOs) struggle to reach this historically stigmatized and largely hidden population with face-to-face interventions. HIV researchers have readily turned to the internet to deliver critical HIV education to this group, with evidence of high effectiveness and acceptability across studies. However, implementation outside of research contexts has been limited and not well studied. We aimed to assess HIV CBOs’ readiness to adopt digital health interventions and identify contextual factors that may contribute to differing levels of readiness.MethodsWe recruited 22 CBOs across the US through a pragmatic request-for-proposals process to deliver Keep It Up! (KIU!), an evidence-based eHealth HIV prevention program. We used mixed methods to examine CBO readiness to adopt digital health interventions (RADHI). Before implementation, CBO staff completed a 5-item RADHI scale (scored 0–4) that demonstrated concurrent and predictive validity. We interviewed CBO staff using semi-structured questions guided by the Consolidated Framework for Implementation Research and compared RADHI score groups on determinants identified from the interviews.ResultsEighty-five staff (range = 1–10 per CBO) completed the RADHI. On average, CBOs reported moderate-to-great readiness (2.74) to adopt KIU!. High RADHI CBOs thought KIU! was a top priority and an innovative program complementary to their existing approaches for their clients. Low RADHI CBOs expressed concerns that KIU! could be a cultural mismatch for their clients, was lower priority than existing programs and services, relied on clients’ own motivation, and might not be suitable for clients with disabilities. Value, appeal, and limitations did not differ by RADHI group.ConclusionsWhile HIV CBOs are excited for the opportunities and advantages of digital interventions, additional pre-implementation and implementation support may be needed to increase perceived value and usability for different client populations. Addressing these limitations is critical to effective digital prevention interventions for HIV and other domains such as mental health, chronic disease management, and transitions in care. Future research can utilize our novel, validated measure of CBOs’ readiness to adopt digital health interventions.Trial registrationNCT03896776, clinicaltrials.gov, 1 April 2019.
