Barriers to implementing contingency management at a methadone treatment clinic: A qualitative study at a tertiary hospital in Tanzania.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionContingency management in addiction behaviors has been widely applied in high income settings. Contingency management entails modification of behavior via the control or manipulation of consequences (contingencies) to the behavior. While a need exists for contingency management in low- and middle- income settings, specifically those of the sub-Saharan Africa region, uptake is low relative to high income settings. This study assessed barriers to implementation of contingency management for methadone treatment clients at the outpatient clinic of a tertiary hospital in Tanzania.
methodsThis study employed a qualitative design and was conducted at Mbeya Zonal Referral Hospital (MZRH). Guided by the consolidated framework of implementation research (CFIR), data were collected from two sources 1) ten purposively selected key informants (health care workers, methadone treatment clients and hospital leaders) who participated in in-depth interviews, and 2) a mini focus group discussion with five participants (two health care providers, two hospital leaders and one leader of methadone treatment clients). We developed semi-structured guides for in-depth interviews and the mini focus group to explore the key barriers. We analyzed the collected data using thematic analysis.
resultsReported barriers revolved around the following key themes: lack of awareness and knowledge regarding contingency management, financial constraints to support implementation, trust between clients and health care workers, Health care workers work load, client behaviors and clinic culture. Participants mentioned lack of awareness and knowledge more frequently compared to other themes.
conclusionIn the context of specialized outpatient care in Tanzania, contingency management faces a variety of barriers. Deliberate efforts to establish and sustain contingency management in these settings require strategies that attend to the identified barriers. If the barriers are overcome, contingency management implementation and sustainment may follow and ultimately improve methadone related health outcome for patients.
