How can Human Resources for Health (HRH) data be aligned efficiently to the current, and future health care needs and ensure targets for Universal Health Coverage (UHC) are reached? To do this, governments and health planners need access to accurate, actionable data about health workers. HISP-SA describes how we have taken advantage of the open architecture of the DHIS2 to facilitate interoperability amongst systems for a comprehensive view of health data.

A data-driven and evidence-based health workforce approach for policy development, planning, and management at all levels, from National to facility, is a key priority for the South African National Department of Health (NDOH). This enables planning for a competent health workforce that is productive, motivated, and empowered. It further supports governance and facilitates strategic leadership and management.

Two critical components of the Human Resource for Health (HRH) information landscape are the HRH Registry and HRH Datawarehouse. HISP-SA has built these using an open standards-based architecture. The centralised HRH Registry contains individual HRH records from multiple sources. This data is aggregated, anonymized, and combined with data from other sources in a Datawarehouse. Data from both HRH Registry and Datawarehouse is available to users through a Portal, which provides a single point of access to the HRH information.

The open architecture includes a Python ETL process to consume data from multiple transactional sources, such as Health Professional Councils, NDOH HR management systems, and universities into a Fast Health Interoperability Recourses (FHIR) server using the Mobile Care Services Discovery (mCSD) profile of the Integrating the Healthcare Enterprise (IHE). Data from the HRH Registry is aggregated and sent from the FHIR server into a DHIS2 Datawarehouse via the ETL process using ADX profile to provide accurate indicators on Health workforce in the country. The architecture further includes an API mesh that facilitates interoperability and reporting from multiple sources. Users can search the registry platform, view public dashboards, and access the DHIS2 Datawarehouse securely from a custom portal. The OpenHIM facilitates interoperability between various systems in the architecture.

The Portal development follows an Agile development approach leveraging security and analytics provided by the DHIS2 platform. So far, data of approximately 11,000 health sector workers are included in the repository. The HRH architecture demonstrates the flexibility of DHIS2 to fulfil multiple roles in an open standards architecture.
