Service planning implications of estimating Primary Health Organisation enrolment rate based on a Health Service Utilisation population rather than a census-derived population

This paper in the New Zealand Medical Journal demonstrates the issue of numerator and denominator mismatch in relation to estimating Primary Health Organisation (PHO) enrolment rates with a census-derived estimated resident population denominator. It uses the Health Service Utilisation (HSU) population denominator as an alternative and demonstrates how this could support efforts to improve PHO enrolment coverage.
