Social equity and primary healthcare financing: lessons from New Zealand.

Abstract

This paper reviews the effect of a primary care financing scheme introduced in New Zealand as a component of the New Zealand Primary Health Care Strategy, a comprehensive reform of the way that primary healthcare was governed, financed and delivered. The population-based funding formulae incorporated an area-based measure of social deprivation and ethnicity in an explicit attempt to improve access to care for certain population groups and fund social interventions aimed at addressing conditions that lead to improved health outcomes. The New Zealand experience shows that introducing a nationwide, comprehensive program to improve access and reduce health disparities is possible. However, the effect of this effort on reducing health disparities is not entirely clear because success ultimately relies on local implementation of a complex set of interventions that need to be evaluated more rigorously. In addition, the partial subsidies for first contact care that came with the Strategy have been shown to improve access, but, the success of this approach relies on compliance by private-practising general practitioners with a fee reduction regimen, which is subject to local variation.
