Optimizing delivery strategies for 3HP TB preventive treatment in Tanzania: A qualitative study on acceptability of family approach in HIV care and treatment centers.

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
Tanzania rolled-out a 12-dose, weekly regimen of isoniazid plus rifapentine (3HP) TB preventive treatment in January 2024. The 3HP completion rate is generally ≥80%, varying by delivery strategy and programmatic setting. Before the roll-out, a mixed methods study was conducted to assess whether a family approach involving family member support, SMS reminders, and three health education sessions was acceptable and optimized 3HP uptake and completion. This paper describes acceptability of the family approach among people living with HIV (PLHIV), treatment supporters (TS), and community health workers (CHWs). This was a qualitative descriptive study in 12 HIV care and treatment centers across six administrative regions. We purposively sampled 20 PLHIV, 12 CHWs for in-depth interviews, and 23 TS for three focus group discussions held between September and December 2023. The theoretical framework of acceptability guided thematic-content analysis using a framework approach. Participants understood that PLHIV have an increased risk for active TB and that 3HP provides shortened treatment for TB disease prevention. They learned about TB and 3HP through health education sessions, but participation of TS was low due to expensive transportation costs to clinics. Receiving support from a trusted person and SMS were perceived as good adherence reminders. The majority reported mild self-limiting side effects but expressed positive attitudes because of the shortened treatment, TB counseling, satisfaction from helping others, lifestyle and work alignment, and reduced work burden. Some PLHIV had difficulties identifying supportive family members, so they chose close friends or CHWs. The family approach to supporting 3HP adherence is widely accepted by PLHIVs, TS, and CHWs in the context of person-centered care that respects their preferences. We recommend its adoption in programmatic settings as a combined approach, considering changes made during the study. However, further research is warranted to assess its acceptance among other populations eligible for 3HP.
