There are two types of ways we can link service statistics.
One is to look at public health indicators/aggregate service delivery indicators reported at the facility level. We would then cross-reference (via the facility) against an HRH indicator, such as the # of HWs by cadre (for that facility).
The second main way is to look at clinical information systems such as a facility based Electronic Medical Record system, or a longitudinal/shared health record (such as in the OpenHIE architecture). Typically here, the health practitioner that performed the service is recorded in the clinical transaction.
