This post explains what the July 24, 2026 PLOS Global Public Health scoping review found about mHealth for task-sharing in Africa and how AI-enabled qualitative research can turn those findings into program-ready evidence. According to Mhlanga et al., PLOS Global Public Health (2026), mHealth was the most used digital health technology in the 15 studies the authors included, and these studies described functions for prevention, screening, treatment delivery, and supervision. Strategic readers, including digital health researchers and implementation teams, will get concrete analytical steps and tool mappings to shorten synthesis time and inform scale decisions.
Key Takeaways
According to Mhlanga et al., PLOS Global Public Health (2026), mHealth is the dominant digital health approach used by non-physician health workers (NPHWs) for task-sharing to prevent and manage non-communicable diseases (NCDs) in Africa: "digital health, particularly mHealth, supports NPHWs in task-sharing for NCD prevention and management in Africa" (PLOS Global Public Health).
- The PLOS review searched until 3 August 2025 and identified 4, 857 citations, screened 71 full texts, and ultimately included 15 studies from eight African countries, as reported in the PLOS article published on July 24, 2026.
- mHealth appeared in 46.7% (7/15) of included studies and community health workers were the most frequent users (46.7%; 7/15), according to Mhlanga et al., PLOS Global Public Health (2026).
- Reported training for NPHWs who used digital tools ranged from two to nine days in studies that documented training, per the PLOS review (Mhlanga et al., 2026).
- Barriers documented by Mhlanga et al., PLOS Global Public Health (2026) include low digital literacy, poor internet connectivity, and inadequate electricity supply, all dated and summarized in the July 24, 2026 publication.
What happened and how the review measured it
Answer: The PLOS scoping review (Mhlanga et al., PLOS Global Public Health, 2026) mapped studies that describe how digital health supports task-sharing for NCDs across Africa, and it used the Joanna Briggs Institute (JBI) scoping review methods and PRISMA-ScR reporting.
Mhlanga et al., PLOS Global Public Health (2026) searched PubMed, Scopus, and Google Scholar through 3 August 2025, identified 4, 857 citations, removed duplicates and exclusions, screened 71 full texts, and included 15 studies from Ghana, Kenya, Mozambique, Nigeria, Rwanda, South Africa, Tanzania, and Zimbabwe.
Mhlanga et al., PLOS Global Public Health (2026) extracted numerical descriptors (publication year, country), study designs, and sample sizes, then applied qualitative content analysis by coding units of meaning and synthesizing categories into themes.
The PLOS review reported four primary functions of mHealth in task-sharing: prevention, screening, treatment delivery, and supervision, and the authors note that evidence of effectiveness was limited to four studies reporting patient outcomes (Mhlanga et al., 2026).
Findings snapshot
| Date / Source | Metric | Value | Implication |
|---|---|---|---|
| Search conducted to 3 Aug 2025 (Mhlanga et al., PLOS Global Public Health, 2026) | Citations identified | 4, 857 | Large initial universe; need rapid screening and synthesis tools |
| Included studies (published by Jul 24, 2026) | Studies included | 15 (from 8 countries) | Evidence patchy and geographically concentrated (26.7% in South Africa) |
| Technology mix (Mhlanga et al., 2026) | Studies using mHealth | 46.7% (7/15) | mHealth is the dominant modality for task-sharing activities |
| Training reported (Mhlanga et al., 2026) | Training duration | 2 to 9 days (reported in 7 studies) | Workforce readiness varies; training needs to be documented and standardized |
| Outcome studies (Mhlanga et al., 2026) | Studies reporting patient outcomes | 4 studies | Limited and mixed effectiveness evidence, especially for prevention |
Implications for digital health researchers and program teams
Answer: Researchers and implementers should prioritize rigorous qualitative synthesis and context-aware evaluation because the PLOS review (Mhlanga et al., 2026) found limited and uneven evidence across countries and functions.
The PLOS review (Mhlanga et al., 2026) shows that mHealth supports screening and treatment delivery by NPHWs, but prevention results were neutral in some trials, so implementers should pair qualitative process data with outcome measures to identify where interventions fail or succeed.
Because Mhlanga et al., PLOS Global Public Health (2026) identified low digital literacy, poor internet, and unreliable electricity as common constraints, program teams should budget for training, offline-capable apps, and device-charging solutions during design.
How Evidano helps teams convert PLOS-style findings into decisions
