Abstract Background As implementation science (IS) in low and middle-income country settings continues to grow and generate interest, there is continual demand for capacity building in the field. Training programs have proliferated, but evaluations of these efforts are sparse and primarily from high-income countries. There is little knowledge about the impact of IS training on students’ careers post-graduation. This evaluation of the first cohort of students who graduated from the 18-month implementation science concentration in HIV/AIDS within the Master of Science program at University of the Witwatersrand in South Africa addresses this gap. Methods We conducted two rounds of virtual interviews with the students, who were from eight African countries, immediately after the training program ended (n = 10 participants) and again five years later (n = 9 participants). The first survey captured student perceptions of IS before they entered the program and their opinions just after graduation. The follow-up evaluated their perceptions five years after graduation. Interviews were recorded, transcribed, and coded in ATLAS.ti (first round) and MAXQDA (second round), using the framework method and thematic analysis. Results Prior to the training, all students, even those with no knowledge of the field, perceived that the IS training program would help them develop skills to address critical public health priorities. These expectations were generally met by the training program, and most students reported satisfaction despite what they felt was a limited timeframe of the program and insufficient mentorship to complete their dissertation projects at their home institutions across the African continent. Five years post-graduation, most of the students did not have jobs in IS but continued applying their training in their roles and had subsequently pursued further education, some in IS-related programs. Conclusions IS training in Africa was clearly seen as valuable by trainees but IS job opportunities remain scarce. Training programs need to be more closely tied to local government priorities, and training for in-country policy and decision-makers is needed to increase demand for qualified IS researchers and practitioners.

Abstract Background Decreasing the burden of Tuberculosis (TB) among PLHIV through TB screening is an effective intervention recommended by the World Health Organization (WHO). However, after over a decade of implementation in Ghana, the intervention does not realize the expected outcomes. It is also not well understood whether this lack of success is due to implementation barriers. Our study, therefore, sought to examine the factors influencing the implementation of the intervention among people living with HIV (PLHIV) attending HIV clinics at district hospitals in Ghana. Methods This was a qualitative study conducted from 6th to 31 May 2019 in three regions of Ghana. We conducted 17 in-depth interviews (IDIs – comprising two regional, six districts and nine facility TB/HIV coordinators) and eight focus group discussions (FGD – consisting of a total of 65 participants) with HIV care providers. The Consolidated Framework for Implementation Research (CFIR) guided the design of interview guides, data collection and analysis. All responses were digitally audio-recorded and transcribed verbatim for coding and analysis using the Framework Approach. Participants consented to the interview and recording. Results The main barriers to TB screening relate to the low commitment of the implementers to screen for TB and limited facility infrastructure for the screening activities. Facilitators of TB screening include (1) ease in TB screening, (2) good communication and referral channels, (3) effective goals and feedback mechanisms, (4) health workers recognizing the need for the intervention and (5) the role of chemical sellers. Conclusions Key barriers and facilitators to the intervention are revealed. The study has shown that there is a need to increase HIV care providers and institutional commitment towards TB screening interventions. In addition, cost issues need to be assessed as they are drivers of sustainability. Our study also advances the field of implementation science through CFIR to better understand the factors influencing the implementation.
