Abstract
Unnecessary hospitalisations for preventable or treatable conditions provides an indication of the health of a country and its systems. We present data on potentially avoidable hospitalisations of Māori and non-Māori non-Pacific (NMNP) under-25-year-olds for medical conditions during the period 2000-2019, with particular focus on the magnitude of inequity by area deprivation. Potentially avoidable hospitalisation rates of under-25 years for medical conditions were consistently higher for Māori than for NMNP over the 20-year study period. The absolute difference in potentially avoidable hospitalisation rates between the most and least deprived areas were greater for Māori than for NMNP in all years of the study. Respiratory conditions and skin infections accounted for more than 60% of potentially avoidable hospitalisations of Māori under-25-year-olds. The persistent trends in deprivation-based inequities in health outcomes for Māori, on both absolute and relative scales, suggest greater attention needs to be paid to implementing effective policy focussed on reducing these deprivation-based inequities and on improving access to and quality of care.
