Deployment Architecture

LAMISPlus is deployed using a Hub and Spoke model. A central hub manages coordination, data synchronisation, and governance across all facilities. Individual facilities connect as spokes, either online or offline. This design ensures that even facilities with poor or no internet connectivity can continue operating and sync their data when connection is restored.

LAMISPlus Deployment Architecture

The Hub​

The national LAMISPlus Hub sits at the centre of the deployment. It maintains a multi-tenant database that holds the master copy of all facility data, provides caching of operational patient data for performance, and serves as the synchronisation point for all spokes.

The hub connects upward to the National Shared Health Record, which includes the Master Patient Index (MPI), Terminology services, National Identity Number (NIN), and aggregate reporting. Governance systems at the Federal Ministry of Health and other MDAs use this layer for programme oversight and National Digital Health Architecture (NDHA) alignment. The National Hub powered by OpenFN handles national deployment, cross-deployment synchronisation, policy orchestration, and compliance monitoring.

Online Spoke Facilities​

Facilities with reliable internet connectivity run as online spokes. They connect directly to the central hub. Clinical staff use LAMISPlus on any browser-capable device. Patient data syncs to the hub in real time, meaning national reports and programme dashboards are always current.

Offline Spoke Facilities​

Facilities with limited or no connectivity run LAMISPlus locally with a local database. The system continues to operate fully during connectivity outages. When the connection is restored, OpenFN handles the synchronisation workflow automatically. No data is lost and no manual intervention is required.

Integration with other systems​

The hub also connects to other point-of-service delivery systems used across the health sector:

  • LIMS (Laboratory Information Management System)
  • NAFDAC (National Agency for Food and Drug Administration and Control)
  • NHMIS (National Health Management Information System)
  • PIMS (Patient Information Management System)
  • NIMC (National Identity Management Commission)
  • Logistics Management

This means LAMISPlus does not operate as an isolated system. Clinical data generated at the facility flows into the national health information ecosystem, and master data from national registries flows back to inform clinical care.
