This fourth national report on the national Key Performance Indicators (nKPIs) data collection is based on data from more than 240 primary health care organisations that received funding from the Australian Government Department of Health to provide services primarily to Aboriginal and Torres Strait Islander people. Information is presented for 22 ‘process-of-care’ and ‘health outcome’ indicators for June 2016, which focus on maternal and child health, preventative health, and chronic disease management. The report shows continuous improvements for the majority of indicators.
