Community health workers — the Bangladeshi model and African adaptations

<p>The community health worker (CHW) is one of the most evidence-supported interventions in twenty-first-century public health. The Bangladesh BRAC model, scaled from the late 1970s onward, demonstrated that trained, supervised, paid lay workers from the community could deliver primary care interventions — oral rehydration therapy, immunisation outreach, tuberculosis directly-observed treatment, family planning counselling — with measured impacts on under-5 mortality that conventional facility-based care had not achieved at the same cost. African adaptations of the model have been uneven, and the unevenness is instructive.</p> <p>Ethiopia&#x27;s Health Extension Worker programme, launched 2003, is the largest formal African CHW deployment. Approximately 40,000 HEWs — salaried, two years of training, deployed at the kebele (community) level — staff a network of around 16,000 health posts. The programme is credited with the dramatic Ethiopian under-5 mortality reduction of the 2000s and 2010s (from 165 per 1,000 live births in 1990 to 49 in 2020). Lasting impact studies — particularly the Ethiopia Health Extension Program impact evaluations by Workie &amp; Ramana — find the programme highly cost-effective with remaining quality variability driven by woreda-level supervision capacity.</p> <p>Rwanda&#x27;s community health programme, structurally similar, employs roughly 60,000 *animators de santé* (volunteer CHWs) supervised by a smaller cadre of paid CHWs at the *umudugudu* level. The volunteer model gets impressive coverage at low salary cost; it is also vulnerable to volunteer turnover and to a structural under-recognition of CHW labour. Liberia&#x27;s Community Health Assistant programme, post-Ebola, took a different path: a smaller but fully paid cadre, with clinical scope expanded toward integrated community case management (iCCM) of childhood illness.</p> <p>What separates the African CHW programmes that have produced sustained mortality reductions from those that have not? Three operational variables, in approximate order of importance. *Pay*: volunteer programmes work briefly, paid programmes work durably. *Supervision*: a paid CHW with weekly clinical supervision performs at multiple-times the effective-care delivery of an unsupervised CHW. *Supply chain*: a CHW without reliable access to amoxicillin, ORS, RDTs, and family-planning commodities is a CHW delivering counselling and referral only — important but bounded.</p> <p>What it most often does *not* depend on, despite long-standing donor preoccupation, is the specific training curriculum, the level of formal education at entry, or the IT platform used for data capture. The Bangladesh-BRAC model assumed minimal entry qualifications, modest training duration, and paper-based recording. Twenty years of African scaling has confirmed this. The interventions that *work* are paid jobs with supervision and supplies — neither high-tech nor high-prestige, but reliably effective when funded. The political question, predictably, is whether finance ministers fund them durably or treat them as expendable programme costs when austerity cycles hit.</p>
