How Nigeria Can Maximize Community Health Workers’ Impact Through Digital Support and Trust-Based Care By Temitayo Okusanya

Community health workers (CHWs) remain one of the most essential yet under-supported pillars of Nigeria’s primary healthcare (PHC) system. They deliver maternal and child health services, support immunization campaigns, educate families on hygiene and nutrition, connect communities to health facilities. Yet, like many parts of the PHC system, they face persistent constraints: inconsistent training, limited supervision, documentation burdens, and gaps in communication with higher-level facilities.
In a study led by Temitayo R. Okusanya, a Nigerian-born health systems researcher, Okusanya and her team examined how community health workers (CHWs) can be integrated into digital information systems to improve public health situational awareness. While conducted in the U.S., the findings resonate strongly with Nigeria’s context, particularly around the need for real-time community data and more trusted frontline workers embedded within local communities

Presented at the 21st Information Systems for Crisis Response and Management (ISCRAM) conference in Germany, the research “Designing Information Flow with Diverse Community Health Workers to Improve Public Health Situational Awareness During COVID-19” provides lessons directly relevant to Nigeria’s efforts to strengthen community-based care and PHC performance.
Lessons for Nigeria’s PHC System
1. Community-Rooted Health Workers Are a Critical Asset — Not a Supplement
One finding from Okusanya’s research that carries significant relevance for Nigeria is the importance of community-rooted health workers. In the U.S. study, CHWs were not external professionals brought in temporarily; they were individuals who lived in the communities they served and had longstanding social ties with residents.
According to Okusanya, this positionality enabled CHWs to build trust rapidly, navigate cultural and linguistic nuances, and collect accurate, context-rich data during household visits. Their community identity was a major factor in improving adherence to referrals, reporting symptoms, and maintaining engagement over time.
Nigeria already has Ward Development Committees and Community Health Extension Workers (CHEWs), but their integration into digital health systems and their role in community engagement remain fragmented. Strengthening and scaling workforce models that prioritize cultural familiarity and trust can help Nigeria unlock the full value of its CHWs—especially in underserved rural and peri-urban communities where mistrust of the formal health system is high.

2. Digital Tools Only Work When They Enhance, Not Burden, CHW Workflows
In the U.S. study, CHWs used mobile phones and basic reporting apps to document household needs, capture health indicators, and initiate referrals. Importantly, the digital tools were designed around their workflow, not imposed from above. The system was simple, mobile, and reduced administrative burden.

Nigeria’s ongoing digital transformation especially DHIS2 expansion, SmartPHCs, and EMR pilots can benefit from this principle. For Nigeria, Okusanya notes that tools must be intuitive and aligned with how CHWs actually work in the field. Too many digital initiatives in LMICs fail because the tools increase workload, require constant connectivity, or do not reflect community realities.
Okusanya states that a Nigeria-focused adaptation could involve:
offline-first mobile tools for low-network settings,
automated dashboards at the LGA and state levels for data-driven decisions,
structured fields for recording context, barriers, and follow-up needs,
built-in referral pathways linking CHWs directly to PHCs and secondary facilities.
By aligning these simple digital innovations with daily work realities, Nigeria could dramatically improve coordination, accountability, and real-time visibility into community-level health needs.

3. Strengthening Service Delivery Through Better Integration
The study also underscores the need for stronger integration between CHWs and formal health facilities. In Nigeria, CHWs often work in isolation, with limited supervision, inconsistent reporting mechanisms, and minimal platforms for clinical escalation.
The U.S. model demonstrated how linkages even when built through simple digital channels can:
clarify responsibilities,
ensure timely referrals,
reduce service fragmentation, and
support consistent follow-up for chronic conditions such as hypertension, diabetes, and mental health.

Strengthening these linkages in Nigeria is essential for building a resilient PHC system.
“Integration is not just about technology. It is about designing workflows that help CHWs, nurses, and facility staff communicate seamlessly. When CHWs are connected to the larger health system, everyone benefits.”
Learning Across Contexts: Why a U.S. Study Matters for Nigeria
While the study draws from an American health context, its lessons resonate deeply with Nigeria’s ongoing PHC reforms. By focusing on underserved populations — many of whom face challenges similar to those in rural and peri-urban Nigeria, the research offers a practical roadmap for adapting global best practices.

Health systems differ, but human needs and frontline realities often overlap. Lessons from one context can illuminate opportunities in another — especially when it comes to strengthening community-based care.”

As Nigeria continues implementing PHC revitalization strategies, experts say the country can benefit from adopting CHW-centered innovations that combine trust, training, and simple digital enhancements.
By positioning CHWs not just as frontline workers but as system connectors and data contributors, Nigeria can build a more resilient, equitable, and responsive primary healthcare system.
