Consequences of barriers to primary health care for children in Aotearoa New Zealand

Financial barriers to primary health care in Aotearoa New Zealand

BACKGROUND

In Aotearoa New Zealand, co-payments to see a general practitioner (GP, family doctor) or collect a prescription are payable by virtually all adults.

OBJECTIVE

To examine the extent to which these user co-payments are a barrier to accessing health care, focussing on inequities for indigenous Māori.

METHODS

Pooled data from sequential waves (years) of the New Zealand Health Survey, 2011/12 to 2018/19 were analysed. Outcomes were self-reported cost barriers to seeing a GP or collecting a prescription in the previous year. Logistic regression was used to estimate odds ratios (ORs) of barriers to care for Māori compared with non-Māori, sequentially adjusting for additional explanatory variables.

RESULTS

Pooled data included 107,231 people, 22,292 (21%) were Māori. Across all years, 22% of Māori (13% non-Māori) experienced a cost barrier to seeing a GP, and 14% of Māori (5% non-Māori) reported a cost barrier to collecting a prescription. The age- and wave-adjusted OR comparing Māori/non-Māori was 1.71 (95% confidence interval [CI]: 1.61, 1.81) for the cost barrier to primary care and 2.97 (95% CI: 2.75, 3.20) for the cost barrier to collecting prescriptions. Sociodemographics accounted for about half the inequity for both outcomes; in a fully adjusted model, age, sex, low income, and poorer underlying health were determinants of both outcomes, and deprivation was additionally associated with the cost barrier to collecting a prescription but not to seeing a GP.

CONCLUSIONS

Māori experience considerable inequity in access to primary health care; evidence supports an urgent need for change to system funding to eliminate financial barriers to care.

Residential mobility and potentially avoidable hospitalisations in a population-based cohort of New Zealand children

BACKGROUND

Residential moves are common in early childhood and associations have been found between residential mobility and adverse child health and well-being outcomes. Although there are studies on potentially avoidable hospitalisations (PAH) in children, few have examined PAH in relation to residential mobility. Our aim, therefore, was to investigate residential mobility and PAH in a population-based cohort of New Zealand children.

METHODS

Using a retrospective cohort design, we analysed data from the Integrated Data Infrastructure for a cohort of 314 283 children born since the start of 2004, who had at least one residential address recorded by 2 years of age. Residential mobility was derived from address data and PAH were determined from hospital discharge data.

RESULTS

Half of the cohort children (52%) experienced at least one residential move by 2 years of age, and 22% experienced two or more moves. Fifteen per cent of the cohort experienced one or more PAH between 2 and 4 years of age. A linear association between residential mobility and PAH was found (relative risk (RR)=1.18, CI 1.17 to 1.19) and this remained robust when adjusting for several covariates. Sensitivity analyses for ambulatory care sensitive hospitalisations (ACSH) and PAH attributable to the housing/physical environment (PAH-HE) produced results very similar to those for PAH (ACSH: adjusted RR (aRR)=1.10, CI 1.09 to 1.11; PAH-HE: aRR=1.11, CI 1.10 to 1.12).

CONCLUSION

This study found a linear association between higher residential mobility and an increased likelihood of PAH in young children. Avenues for further investigation are suggested.
