The DHIN 2025 Connectathon Implementation Guide (IG) brings together multiple tracks under a single standards-based framework to demonstrate, test, and advance healthcare interoperability in Nigeria and across Africa.
This IG is rooted in the WHO SMART Guidelines approach (Standards-based, Machine-readable, Adaptable, Requirements-based, Testable). Each track leverages Digital Adaptation Kits (DAKs) and HL7 FHIR R4-based artifacts to ensure that systems can exchange health information seamlessly, securely, and in alignment with national and international best practices.
Background
Nigeria’s health information ecosystem is characterized by fragmented, siloed systems that limit continuity of care, decision-making, and efficiency. The Digital Health Interoperability Network (DHIN) convenes stakeholders—including regulators, providers, developers, insurers, and innovators—to design and test practical interoperability solutions through structured connectathons.
This IG documents the machine-readable artifacts, profiles, and value sets required to implement the 2025 DHIN Connectathon tracks:
Health Insurance & Claims
MNCH Referral
ePharmacy (ePrescription & eDispensing)
Immunization
Medical Devices Communication
Each track builds on existing DAKs, regulatory frameworks, and stakeholder-driven priorities, providing reference implementations for future production systems.
Scope of the FHIR Implementation Guide
This IG addresses the following cross-cutting goals:
Standardize profiles, value sets, and extensions for each track.
Enable secure interoperable data exchange across health facilities, pharmacies, insurers, referral networks, immunization registries, and medical device platforms.
Support decision-support, regulatory compliance, and real-time data exchange through SMART-on-FHIR and open APIs.
Provide artifacts for testing and conformance validation during and beyond the Connectathon.
