Unmasking hidden disparities: a comparative observational study examining the impact of different rurality classifications for health research in Aotearoa New Zealand

Is there a difference in ischaemic heart disease deaths that occur without a preceding hospital admission in people who live in rural compared with urban areas of Aotearoa New Zealand? An observational study

OBJECTIVES

Unlike comparable countries, acute coronary syndrome (ACS) mortality is similar among patients who present to rural and urban hospitals in Aotearoa New Zealand (NZ). The aim of this study was to determine whether differences in ischaemic heart disease (IHD) deaths that occurred without a preceding hospital admission in rural and urban populations explained this finding.

DESIGN

Retrospective observational study using the National Mortality Collection (MORT) and National Minimum Dataset (NMDS) for hospital discharges datasets.

SETTING

People in NZ who died from IHD were categorised based on their rural-urban status (U1 (major urban), U2 (large urban) and rural) using the Geographic Classification for Health and prioritised ethnicity (Māori-NZ's Indigenous population and non-Māori).

PARTICIPANTS

All people 20+ years who died from IHD between July 2011 and December 2018.

PRIMARY AND SECONDARY OUTCOMES

The outcome was the lack of a hospital admission preceding IHD death, identified by linking the NMDS with MORT. This was measured for the 30 days and 1 year prior to death and for all-cause and IHD hospitalisations separately.

RESULTS

Of the 37 296 deaths, a similar percentage of rural and urban residents died without an all-cause (rural 63.2%, U2 60.8%, U1 62.8%) or IHD (rural 70.9%, U2 69.0%, U1 70.1%) admission in the preceding 30 days, or without an all-cause (rural 32.8%, U2 35.5%, U1 35.5%) or IHD (rural 52.7%, U2 52.6%, U1 51.9%) admission in the preceding year. Exceptions were deaths that occurred without a prior admission for rural non-Māori aged 55-64 (higher odds) and 75+ years (lower odds) compared with U1 non-Māori 55-64 and 75+ years, respectively, across all four outcome measures.

CONCLUSIONS

This study suggests that the lack of difference in ACS mortality for patients who present to NZ rural and urban hospitals is not explained by IHD death that occurred without a recent preceding hospital admission.

He Aroka Urutā. Rural health provider perspectives of the COVID-19 vaccination rollout in rural Aotearoa New Zealand with a focus on Māori and Pasifika communities: a qualitative study

Introduction From a coronavirus disease (COVID-19) pandemic perspective, Aotearoa New Zealand (NZ) rural residents formed an at-risk population, and disparities between rural and urban COVID-19 vaccination coverage have been found. Aim To gain insight into factors contributing to the urban-rural COVID-19 vaccination disparity by exploring NZ rural health providers' experiences of the vaccine rollout and pandemic response in rural Māori and Pasifika communities. Methods Rural health providers at four sites participated in individual or focus group semi-structured interviews exploring their views of the COVID-19 vaccine rollout. Thematic analysis was undertaken using a framework-guided rapid analysis method. Results Twenty interviews with 42 participants were conducted. Five themes were identified: Pre COVID-19 rural situation, fragile yet resilient; Centrally imposed structures, policies and solutions - urban-centric and Pakehā focused; Multiple logistical challenges - poor/no consideration of rural context in planning stages resulting in wasted resource and time; Taking ownership - rural providers found geographically tailored, culturally anchored and locally driven solutions; Future directions - sustained investment in rural health services, including funding long-term integrated (rather than 'by activity') health services, would ensure success in future vaccine rollouts and other health initiatives for rural communities. Discussion In providing rural health provider perspectives from rural areas serving Māori and Pasifika communities during the NZ COVID-19 vaccine rollout, the importance of the rural context is highlighted. Findings provide a platform on which to build further research regarding models of rural health care to ensure services are designed for rural NZ contexts and capable of meeting the needs of diverse rural communities.

The TSANZ and Lung Foundation Australia 2023 landscape survey of lung cancer care across Australia and Aotearoa New Zealand

BACKGROUND AND OBJECTIVE

Unwarranted variations in lung cancer care have been well described in both Australia and Aotearoa New Zealand, with shortfalls in hospital-based workforce and infrastructure previously demonstrated. A survey of lung cancer clinicians was performed to gain an updated understanding of current workforce and infrastructure.

METHODS

An online Qualtrics survey included questions on institutional demographics, estimated lung cancer case load, multidisciplinary team (MDT) characteristics including workforce and local infrastructure. We sought to obtain one response from every institution treating lung cancer in Australia and Aotearoa New Zealand.

RESULTS

Responses were received from 89 institutions, estimated to include 85% centres treating lung cancer in Australia and 100% of public hospitals in Aotearoa New Zealand. Lung cancer nurse specialist and Nuclear Medicine are poorly represented in multidisciplinary teams (MDTs) with just 34/88 (38%) institutions fulfilling recommended core workforce for MDT meetings. Case presentation is low with 32/88 (36%) regularly discussing all lung cancer patients at MDT. Metropolitan institutions appear to have a more comprehensive range of services on site, compared to non-metropolitan institutions. Few (4/88) institutions have embedded smoking cessation services. Compared to the previous 2021 Landscape Survey, thoracic surgery representation and core MDT workforce have improved, with modest change in specialist nurse numbers.

CONCLUSION

This wide-reaching survey has identified persistent deficiencies and variations in lung cancer workforce and gaps in infrastructure. Multidisciplinary collaboration and care coordination are needed to ensure all patients can access timely and equitable lung cancer care.

Te Paatu o Te Ao Hurihuri - pandemic-related virtual adaptation of an established marae-based workshop for rural doctors: a qualitative study

Introduction Due to COVID-19 pandemic restrictions in Aotearoa New Zealand, an established remote community marae-based workshop (a component of a postgraduate rural medical programme) was converted into a virtual platform. Aim The aim of this study was to explore student and teacher experiences of this virtual adaptation with focus on cultural aspects. Methods A qualitative exploratory study was undertaken that involved document review and qualitative interviews. Students and teachers were invited to participate. Semi-structured interviews were conducted. Thematic analysis was undertaken using a framework-guided rapid analysis method. The two participant groups' data were analysed concurrently but separately. Results Students found the virtual workshop valuable in furthering their knowledge of Māori culture, cross-cultural communication skills and health inequities in rural clinical practice. Through the innovative efforts of their teachers, they felt some sense of connection with the remote locality and its people. Teachers were able to impart knowledge, connect and keep everyone culturally safe through their commitment and adaptability. However, moving to a virtual platform meant compromise to the cultural experience for students and loss of sharing the learning and experience with their place and their people. Discussion In the event of a further pandemic or other emergency situation, where strong established relationships exist, replacing an in-person remote marae-based workshop with a virtual workshop, while limited, is achievable and has value. When urban tertiary institutions partner with remote Māori communities to deliver virtual teaching, caution is needed in ensuring sustained transparency in priorities and expectations to avoid further exacerbations of power imbalance and resulting loss of value.

Comparison of urban and rural mortality rates across the lifespan in Aotearoa/New Zealand: a population-level study

BACKGROUND

Previous studies undertaken in New Zealand using generic rurality classifications have concluded that life expectancy and age-standardised mortality rates are similar for urban and rural populations.

METHODS

Administrative mortality (2014-2018) and census data (2013 and 2018) were used to estimate age-stratified sex-adjusted mortality rate ratios (aMRRs) for a range of mortality outcomes across the rural-urban spectrum (using major urban centres as the reference) for the total population and separately for Māori and non-Māori. Rural was defined according to the recently developed Geographic Classification for Health.

RESULTS

Mortality rates were higher overall in rural areas. This was most pronounced in the youngest age group (<30 years) in the most remote communities (eg, all-cause, amenable and injury-related aMRRs (95% CIs) were 2.1 (1.7 to 2.6), 2.5 (1.9 to 3.2) and 3.0 (2.3 to 3.9) respectively. The rural:urban differences attenuated markedly with increasing age; for some outcomes in those aged 75 years or more, estimated aMRRs were <1.0. Similar patterns were observed for Māori and non-Māori.

CONCLUSION

This is the first time that a consistent pattern of higher mortality rates for rural populations has been observed in New Zealand. A purpose-built urban-rural classification and age stratification were important factors in unmasking these disparities.
