A formative evaluation of potential barriers and facilitators to inform effective implementation of a community-based hypertension care program in rural South Africa: The IMPACT-BP trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: In rural KwaZulu-Natal Province, South Africa, less than 25 % of persons with hypertension have controlled blood pressure. We conducted a formative evaluation of current clinic-based care to identify barriers and facilitators that could impact effective implementation of a community-based hypertension intervention (IMPACT-BP). Methods: We conducted individual interviews and group discussions with clinic managers, nurses, community health workers (CHWs), community leaders, and patients to identify barriers and facilitators experienced in clinic-based hypertension care, which could affect the acceptability, feasibility, and implementation of the IMPACT-BP intervention. The Conceptual Model of Implementation Research and the Theoretical Framework of Acceptability guided the design of data collection instruments and analysis. Qualitative data collection was performed by trained social science research assistants, recorded, transcribed, translated, and analyzed using thematic analysis. Results: Forty-one participants (92 % women) participated in group discussions (n = 32) or individual interviews (n = 9). Barriers to intervention acceptability and feasibility included inadequate levels of staffing, high patient volumes, distrust of CHWs' work at clinics and in the community, and insufficient training and equipment for CHWs. Facilitators included home delivery of medications by CHWs. Conclusions: Our findings allowed us to identify specific adaptations to the intervention implementation strategy to make the proposed community-based intervention acceptable and feasible in this setting. Adaptations included employing dedicated CHWs and nurses for trial-related activities, developing an expanded CHW training module on hypertension knowledge, teaching CHWs to measure blood pressure and subsequently train patients to do the same, and training CHWs to educate patients about hypertension management.
