Integrating a DHIS2 Tracker into eRHMIS2
Background: National DHIS2 platforms often host multiple programmes supporting routine reporting and surveillance. Integrating redesigned tracker modules into existing national systems presents technical and operational challenges, particularly when systems are already in active use. In Sri Lanka, the under-five child death surveillance tracker required integration into eRHMIS2, the national DHIS2-based platform for individual-level maternal and child health data. Integration approach: This study describes the integration of a redesigned DHIS2 Tracker module into the live eRHMIS2 system. The integration strategy prioritised platform reuse, continuity of services, and alignment with national governance structures. System redesign focused on ensuring compatibility with existing metadata standards, user hierarchies, and access control mechanisms within eRHMIS2. Implementation: The redesigned tracker was first developed and tested in a controlled DHIS2 environment. Following validation, it was migrated into eRHMIS2 using staged deployment to avoid disruption to ongoing surveillance activities. Existing user management, organisational unit structures, and role-based access controls were reused to ensure consistency and minimize retraining. Technical documentation and operational guidance supported the transition. Outcomes and lessons learned: Integration improved coherence across national surveillance systems and reduced fragmentation between parallel DHIS2 implementations. The experience highlights the importance of phased deployment, reuse of national DHIS2 infrastructure, and close coordination between technical and programme teams when integrating new tracker modules into live systems. Conclusion: This case study demonstrates practical strategies for integrating redesigned DHIS2 Tracker modules into national platforms, supporting sustainable scale-up without service disruption.
