Outcomes are presented from an evaluation of primary care investment measured through the Capital and Coast District Health Board’s (DHB) Primary Health Care Framework. The Framework was developed in 2002/2003 to guide funding decisions at a DHB level, and to provide a transparent basis for evaluation of the implementation of the Primary Health Care Strategy in this district. Analyses of quantitative and qualitative data revealed a link between investment in primary health care, increased access to primary care for high-need populations, workforce redistribution, and improved health outcomes. Among enrolled populations, ambulatory sensitive hospitalisations and emergency department use reduced and the District’s immunisation coverage improved markedly. Funding and contracting initiatives enhanced both ‘mainstream’ and ‘niche’ providers and together with community-based health initiatives, had a measurable impact on a range of health indicators and inequalities. Māori primary care providers improved access for Māori as well as their enrolled populations of Pacific and Other ethnicity. There was growth and redistribution in the primary care workforce, which improved the availability of general practitioners, nurses, and community workers in poorer communities.
