Evaluating community-based digital health interventions to improve COVID-19 outcomes in rural Indonesia: a quasi-experimental study.
Article in BMJ health & care informatics, 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
objectivesCOVID-19 has challenged health systems in low-income and middle-income countries, particularly in rural areas where communities face barriers to information, prevention and timely care. Digital health interventions delivered through community health workers (CHWs) offer a promising approach to closing these gaps. This study evaluated whether a CHW-led digital intervention improved knowledge, attitudes and practices (KAP), vaccination uptake, COVID-19 outcomes and access to hospital care in rural Indonesia.
methodsA quasi-experimental study was conducted from June 2022 to June 2023 with 10 023 individuals across four intervention and four control villages in Malang Regency. In intervention villages, CHWs used a mobile application (
resultsIntervention participants demonstrated greater improvements in attitudes (mean change=3.5, SD=2.1) and practices (0.02, SD=2.2) compared with controls (attitudes: -2.2, SD=4.6; practices: -2.0, SD=2.1). Vaccine uptake was higher in intervention villages (50.6% vs 40.9%), while COVID-19 diagnoses were lower (1.5% vs 2.4%). Among diagnosed cases, hospitalisation was more frequent in intervention villages (21.3% vs 14.5%). DISCUSSION: The intervention enhanced CHWs' effectiveness in promoting protective behaviours, facilitating early detection and improving referrals. These findings highlight the potential scalability of CHW-led digital health strategies in low-resource settings.
conclusionIntegrating digital tools into CHW-led care can strengthen COVID-19 prevention, vaccination and access to hospital care in rural populations.
