Health outcomes of children in state care in Aotearoa New Zealand.

AIM: This study aims to provide an overview of the association between being in the custody of the chief executive of Oranga Tamariki (the child welfare agency of the New Zealand (NZ) government) and all-cause hospitalisation and mortality. METHODS: This was a national retrospective cohort study using linked administrative data from the Integrated Data Infrastructure. Data were obtained for all 0-17 year-olds living in NZ on 31 December 2013. In-care status was ascertained at this point. Outcomes of all-cause hospitalisation and all-cause mortality were assessed between 1 January 2014 and 31 December 2018. Adjusted models incorporated age, sex, ethnicity, level of socioeconomic deprivation and rural/urban status. RESULTS: There were 4650 in-care children and 1 009 377 not-in-care children in NZ on 31 December 2013. Of those in care, 54% were male, 42% lived in the most deprived areas and 63% identified as Maori. Adjusted models showed that in-care children were 1.32 (95% CI 1.27-1.38) times more likely to be hospitalised than not-in-care children and 3.64 (95% CI 2.47-5.40) times more likely to die. CONCLUSION: This cohort study highlights that the care and protection system prior to 2018 was not preventing children in its care from experiencing severe adverse outcomes. Overseas research has previously been relied on when making practice and policy decisions around child care and protection in NZ, so this research will provide valuable insight into best practice in an NZ context.

Barriers to equitable maternal health in Aotearoa New Zealand: an integrative review.

BACKGROUND: The purpose of this review was to examine the literature for themes of underlying social contributors to inequity in maternal health outcomes and experiences in the high resource setting of Aotearoa New Zealand. These 'causes of the causes' were explored and compared with the international context to identify similarities and New Zealand-specific differences. METHOD: A structured integrative review methodology was employed to enable a complex cross disciplinary analysis of data from a variety of published sources. This method enabled incorporation of diverse research methodologies and theoretical approaches found in the literature to form a unified overall of the topic. RESULTS: Six integrated factors - Physical Access, Political Context, Maternity Care System, Acceptability, Colonialism, and Cultural factors - were identified as barriers to equitable maternal health in Aotearoa New Zealand. The structure of the maternal health system in New Zealand, which includes free maternity care and a woman centred continuity of care structure, should help to ameliorate inequity in maternal health and yet does not appear to. A complex set of underlying structural and systemic factors, such as institutionalised racism, serve to act as barriers to equitable maternity outcomes and experiences. Initiatives that appear to be working are adapted to the local context and involve self-determination in research, clinical outreach and community programmes. CONCLUSIONS: The combination of six social determinants identified in this review that contribute to maternal health inequity is specific to New Zealand, although individually these factors can be identified elsewhere; this creates a unique set of challenges in addressing inequity. Due to the specific social determinants in Aotearoa New Zealand, localised solutions have potential to further maternal health equity.

Interventions to improve vaccine coverage of pregnant women in Aotearoa New Zealand.

Introduction Maternal vaccination against influenza and pertussis protects mothers and babies from severe disease and is recommended and funded in Aotearoa New Zealand. Despite this, maternal vaccination uptake is low, varies by region and is inequitable, with Maori and Pacific mama (mothers) less likely to receive vaccination. Aim To determine what interventions currently exist to support and encourage maternal vaccination against influenza and pertussis and what changes and interventions could be implemented to improve coverage, with a focus on Maori and Pacific hapu mama (pregnant mothers). Methods Interviews with six participants with diverse roles in the vaccination workforce were conducted. Participants were involved in education, certification and supporting vaccinators, high-level strategising, and vaccination. Interviews aimed to determine what interventions currently exist for hapu mama, what changes need to be made to improve coverage and how Maori and Pacific people have been specifically engaged. Qualitative data analysis was used to determine themes. Results Participants identified that interventions must focus on prioritising and emphasising the importance of maternal vaccination, promoting collaboration and innovation, making interventions accessible, and empowering Maori- and Pacific-driven avenues to vaccination. To create positive foundations, participants identified the importance of building and maintaining trust and affording mothers' time and autonomy in vaccination. Discussion Healthcare professionals need to proactively engage hapu mama about vaccination and collaborate in service delivery. Interventions must be suitably accessible and allow for the autonomy of hapu mama over vaccination decisions. Equity should be considered at the foundation of vaccine interventions to improve the accessibility of vaccines to all communities.

A new national health system: the opportunity to address data quality issues in maternal immunisation coverage.

AIM: Maternal immunisation coverage is suboptimal in Aotearoa New Zealand. Our objective was to highlight discrepancies resulting from how maternal immunisation coverage for pertussis and influenza is measured in Aotearoa New Zealand. METHOD: A retrospective cohort study of pregnant people was undertaken using administrative datasets. Maternity and immunisation data from three sources (National Immunisation Register [NIR], general practice [GP], and pharmaceutical claims) were linked to determine the proportion of immunisation records not recorded in the NIR but captured in claims data, and to compare this with coverage data available from Te Whatu Ora - Health New Zealand. RESULTS: We found that while increasing numbers of maternal immunisations are being captured in the NIR, around 10% remain unrecorded on the NIR, but within claims datasets. CONCLUSION: Accurate maternal immunisation coverage data is important for public health action. Implementation of the whole-of-life Aotearoa Immunisation Register (AIR) is an important opportunity to improve completeness and consistency of maternal immunisation coverage reporting.

Social determinants and inequitable maternal and perinatal outcomes in Aotearoa New Zealand.

OBJECTIVES: Aotearoa New Zealand has demonstrable maternal and perinatal health inequity. We examined the relationships between adverse outcomes in a total population sample of births and a range of social determinant variables representing barriers to equity. METHODS: Using the Statistics New Zealand Integrated Data Infrastructure suite of linked administrative data sets, adverse maternal and perinatal outcomes (mortality and severe morbidity) were linked to socio-economic and health variables for 97% of births in New Zealand between 2003 and 2018 (~970,000 births). Variables included housing, economic, health, crime and family circumstances. Logistic regression examined the relationships between adverse outcomes and social determinants, adjusting for demographics (socio-economic deprivation, education, parity, age, rural/urban residence and ethnicity). RESULTS: Maori (adjusted odds ratio = 1.21, 95% confidence interval = 1.18-1.23) and Asian women (adjusted odds ratio 1.39, 95% confidence interval = 1.36-1.43) had poorer maternal or perinatal outcomes compared to New Zealand European/European women. High use of emergency department (adjusted odds ratio = 2.68, 95% confidence interval = 2.53-2.84), disability (adjusted odds ratio = 1.98, 95% confidence interval = 1.83-2.14) and lack of engagement with maternity care (adjusted odds ratio = 1.89, 95% confidence interval = 1.84-1.95) had the strongest relationship with poor outcomes. CONCLUSION: Maternal health inequity was strongly associated with a range of socio-economic and health determinants. While some of these factors can be targeted for interventions, the study highlights larger structural and systemic issues that affect maternal and perinatal health.

Do maternity services in New Zealand's public healthcare system deliver on equity? Findings from structural equation modelling of national maternal satisfaction survey data.

BACKGROUND: Birthing outcomes in New Zealand are demonstrably inequitable based on governmental reports and research. However, the last Ministry of Health maternal satisfaction survey in 2014 indicated that 77% of women were satisfied or very satisfied with care. This study used data from the maternal satisfaction survey to examine aspects of inequity in reported satisfaction with care. METHODS: Structural Equation Modelling (SEM) was used to infer latent variables of satisfaction with equity domains from responses to the satisfaction survey. Additional data (residential location and deprivation score), not used in the Ministry of Health primary analysis, were provided and included in this modelling. RESULTS: SEM showed that satisfaction was not equitably distributed. Younger women, those from areas of high socio-economic deprivation, and remote rural women were most likely to be affected by dissatisfaction associated with physical access, cultural care, information provided, and/or barriers to equity associated with additional costs (all p<0.05). Financial burden of additional costs was also unevenly distributed. CONCLUSION: While these findings are congruent with other research on the association between social determinants and maternal satisfaction, it is concerning that they remain sources of inequity in New Zealand twenty years after they were first identified as priorities to address. On the basis of this study, urgent attention needs to be paid to removing sources of inequity within the health system and maternity care in particular.
