IntroductionIn Aotearoa New Zealand, being enrolled with a Primary Health Care (PHC) provider furnishes opportunities for lower cost access to PHC, preventative care and secondary health care services, and provides better continuity of care. We examine the characteristics of populations not enrolled, and whether enrolment is associated with amenable mortality.MethodWe retrieved records of all deaths registered 2008 to 2017 in Aotearoa New Zealand, which included demographic and primary cause of death information. Deaths were classified as premature (aged under 75 years) or not, and amenable to health care intervention or not. The Primary Health Organisation (PHO) Enrolment Collection dataset provided the PHC enrolment status. Logistic regression was used to estimate the risk of amenable deaths by PHO enrolment status, adjusted for the effects of age, sex, ethnicity and deprivation.ResultsA total of 308,628 mortality records were available. Of these, 38.2% were premature deaths, and among them 47.8% were amenable deaths. Cardiovascular diseases made up almost half of the amenable deaths. Males, youths aged 15-24 years, Pacific peoples, Māori and those living in the most socio-economically deprived areas demonstrated a higher risk of amenable mortality compared to their respective reference category. One in twenty (4.3%) people who had died had no active enrolment status in any of the calendar years in the study. The adjusted odds of amenable mortality among those not enrolled in a PHO was 39% higher than those enrolled [Odds Ratio = 1.39, 95% Confidence Interval 1.30-1.47].ImplicationsBeing enrolled in a PHC system is associated with a lower level of amenable mortality. Given demonstrated inequities in enrolment levels across age and ethnic groups, efforts to improve this could have significant benefits on health equity. |
