Implementing Implementation Research: Teaching Implementation Research to HIV Researchers.

IS training opportunities range from degree programs to short- and longer-term professional development institutes and community-focused institutional trainings. Until recently, there have not been extensive dedicated opportunities for implementation research training for HIV-focused investigators. To meet this gap, an inter-Center for AIDS Research IS Fellowship for early-stage investigators was launched in 2019, building on lessons learned from dissemination and implementation training programs. Key components of the HIV-focused IS fellowship include didactic training, mentorship, grant-writing, and development of HIV-IS collaborative networks. Fellows to-date were two-thirds junior faculty and one-third post-doctoral fellows, the majority (69%) with prior public health training. Perceived value of the program was high, with a median rating of 9 [IQR 8-9] on a 10-point scale. Overall, 22/27 (81%) Fellows from the first cohort submitted IS-related grants within 12 months of Fellowship completion, and by 1 year 13 grants had been funded among 10 investigators, 37% overall among Fellows. Mentors identified framing of IS questions as the top-ranked training priority for HIV-investigators. Increasing knowledge of the utility of IS may support more grants focused on optimal implementation of HIV treatment and prevention strategies. Experiences from mentors and trainees engaged in an IS-focused fellowship for HIV investigators demonstrate the demand and value of a dedicated training program and reinforce the importance of mentorship.
