Leptospirosis in Aotearoa New Zealand: Protocol for a Nationwide Case-Control Study.

BACKGROUND: In Aotearoa New Zealand, 90% of patients with notified leptospirosis (a zoonotic bacterial disease) have been men working in agricultural industries. However, since 2008, the epidemiology of notified cases has been gradually changing, that is, more women are affected; there are more cases associated with occupations traditionally not considered high risk in New Zealand; infecting serovars have changed; and many patients experience symptoms long after infection. We hypothesized that there is a shift in leptospirosis transmission patterns with substantial burden on affected patients and their families. OBJECTIVE: In this paper, we aimed to describe the protocols used to conduct a nationwide case-control study to update leptospirosis risk factors and follow-up studies to assess the burden and sources of leptospirosis in New Zealand. METHODS: This study used a mixed methods approach, comprising a case-control study and 4 substudies that involved cases only. Cases were recruited nationwide, and controls were frequency matched by sex and rurality. All participants were administered a case-control questionnaire (study 1), with cases being interviewed again at least 6 months after the initial survey (study 2). A subset of cases from two high-risk populations, that is, farmers and abattoir workers, were further engaged in a semistructured interview (study 3). Some cases with regular animal exposure had their in-contact animals (livestock for blood and urine and wildlife for kidney) and environment (soil, mud, and water) sampled (study 4). Patients from selected health clinics suspected of leptospirosis also had blood and urine samples collected (study 5). In studies 4 and 5, blood samples were tested using the microscopic agglutination test to test for antibody titers against Leptospira serovars Hardjo type bovis, Ballum, Tarassovi, Pomona, and Copenhageni. Blood, urine, and environmental samples were also tested for pathogenic Leptospira DNA using polymerase chain reaction. RESULTS: Participants were recruited between July 22, 2019, and January 31, 2022, and data collection for the study has concluded. In total, 95 cases (July 25, 2019, to April 13, 2022) and 300 controls (October 19, 2019, to January 26, 2022) were interviewed for the case-control study; 91 cases participated in the follow-up interviews (July 9, 2020, to October 25, 2022); 13 cases participated in the semistructured interviews (January 26, 2021, to January 19, 2022); and 4 cases had their in-contact animals and environments sampled (October 28, 2020, and July 29, 2021). Data analysis for study 3 has concluded and 2 manuscripts have been drafted for review. Results of the other studies are being analyzed and the specific results of each study will be published as individual manuscripts.. CONCLUSIONS: The methods used in this study may provide a basis for future epidemiological studies of infectious diseases. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/47900.

Principles and strategies for improving the prevention of cardio-metabolic diseases in indigenous populations: An international Delphi study.

The disparity in life expectancy between Indigenous and non-Indigenous populations, including within high-income countries, is driven by a heightened risk of cardio-metabolic diseases. The current study recruited independent panels of experts in Indigenous cardio-metabolic health from Australia, New Zealand and the United States, in order to establish local consensus opinion and initiate dialogue on appropriate prevention strategies. Therefore, a three-round Delphi process was used to consolidate and compare the opinions of 60 experts, 20 from each country. Round one, the experts were asked twelve open-ended questions across six domains: (i) prevention; (ii) consultation; (iii) educational resources; (iv) societal issues; (v) workforce issues; (vi) culture and family. Round two, the experts completed a structured questionnaire based on results from the first round, in which they ranked items according to their importance. Final round, the experts were asked to re-rank the same items after receiving summary feedback about the rank ordering from the previous round. Several themes emerged common to all three countries: (i) socio-economic and education inequalities should be addressed; (ii) educational, behaviour change and prevention strategies should address physical environmental determinants and be responsive to the local context, including being culturally appropriate; and (iii) cultural appropriateness can be achieved through consultation with Indigenous communities, cultural competency training, use of Indigenous health workers, and use of appropriate role models. These findings highlight several key priorities that can be used to initiate dialogue on appropriate prevention strategies. Such strategies should be contextualized to the local Indigenous populations.

The role and potential of community-based cancer care for Maori in Aotearoa/New Zealand.

AIM: To investigate the contribution to cancer care and prevention by Maori health provider organisations (MHPs) in Aotearoa/New Zealand. METHODS: A nationwide postal survey of all MHPs (n=253) was undertaken in 2011. The response rate was 55%. RESULTS: We found that MHPs are delivering a wide range of programmes including cancer prevention services focussed on health promotion, advocacy, information and support. MHPs identified financial hardship, transport difficulties, and lack of information as the greatest barriers to cancer care. Culturally safe care by mainstream providers would improve cancer service provision overall. The importance of trust and long-term relationships, with a focus on families rather than individual-based care, was highlighted. CONCLUSION: These findings could lead to substantial improvements in quality of life for Maori cancer patients. This is the first study to show how indigenous health providers contribute to cancer care and prevention in Aotearoa/New Zealand.

Exploring Maori cancer patients', their families', community and hospice views of hospice care.

BACKGROUND: Despite poor cancer survival statistics, Maori do not readily access hospice services. This study aims to explore how hospice services respond to Maori by investigating the different influences and interactions between three perspectives of hospice care. METHOD: The authors conducted a Maori-centred, cross-sectional qualitative study by undertaking semi-structured interviews with hospice patients and whanau (families) (n=8), hospice representatives (n=4), and representatives from three Maori health provider organisations (n=5). CONCLUSIONS: The study found that negative perceptions of hospice are being changed by hospices' relationships with other organisations and positive stories from whanau. Involvement from whanau, continuity of care and after-hours care with a greater Maori workforce and a further emphasis on culturally safe care are critical for this work to gain momentum. Findings can be of use to further develop quality of care indicators that reflect the perspectives of patients and whanau, and those who provide their care.

Cancer care decision making in multidisciplinary meetings.

Little research has been undertaken on the actual decision-making processes in cancer care multidisciplinary meetings (MDMs). This article was based on a qualitative observational study of two regional cancer treatment centers in New Zealand. We audiorecorded 10 meetings in which 106 patient cases were discussed. Members of the meetings categorized cases in varying ways, drew on a range of sources of authority, expressed different value positions, and utilized a variety of strategies to justify their actions. An important dimension of authority was encountered authority-the authority a clinician has because of meeting the patient. The MDM chairperson can play an important role in making explicit the sources of authority being drawn on and the value positions of members to provide more clarity to the decision-making process. Attending to issues of process, authority, and values in MDMs has the potential to improve cancer care decision making and ultimately, health outcomes.

'It's whanaungatanga and all that kind of stuff': Maori cancer patients' experiences of health services.

INTRODUCTION: There are unacceptable ethnic differences in cancer survival in Aotearoa/New Zealand. For people with cancer, quality of life and survival are shaped by access to care, but research on Maori access to, and through, cancer care is limited. Internationally, research has shown that primary care plays an important role in providing patient-centred, holistic care and information throughout the cancer care journey. Additionally, Maori health providers provide practical support and facilitate access to all levels of health care. Here we describe the cancer journeys of Maori patients and whanau and identify factors that may facilitate or inhibit access to and through cancer care services. METHODS: Twelve Maori patients affected by cancer and their whanau (family) in the lower North Island took part in face-to-face semi-structured interviews exploring their experiences of cancer screening, diagnosis, treatment, survival and palliative care. FINDINGS: Three key areas were identified that impacted upon the cancer care journey: the experience of support; continuity of care; and the impact of financial and geographic determinants. CONCLUSION: Primary care plays a key role in support and continuity of care across the cancer journey. Alongside interpersonal rapport, a long-term relationship with a primary health provider facilitated a more positive experience of the cancer care journey, suggesting that patients with a 'medical home' are happier with their care and report less problems with coordination between services. Positive, longstanding relationships with general practitioners and Maori health providers assisted patients and whanau with the provision and understanding of information, alongside practical support.

Clinicians' views on introducing epidermal growth factor receptor testing in New Zealand.

AIM: Inequities exist in the outcomes of patients diagnosed with lung cancer in New Zealand, with Maori (the indigenous population) having significantly higher diagnosis rates and poorer survival. We investigated the feasibility of introducing epidermal growth factor receptor (EGFR) testing into New Zealand as one step to address these inequities. METHODS: An anonymous electronic questionnaire was distributed to clinicians from specialties involved in lung cancer management. Questions were grouped around topics including challenges in lung cancer management, EGFR testing, targeted therapy, costs and interest in the development of a national lung tissue bank. RESULTS: In total, 61 clinicians responded and noted that few of their non-small-cell lung cancer patients were tested for EGFR mutations. Most clinicians (84%) would prefer a centralized testing service and 95% would use an overseas laboratory if publicly funded; however 62% did not know or had no preference for test procedures. Under half (46%) had used tyrosine kinase inhibitors with only a small number of patients and 79% supported the development of a lung tissue bank. CONCLUSION: While most respondents had little experience with EGFR testing, clinicians supported its introduction into New Zealand. However, a number of potential issues, including cost, laboratory expertise and the need for improved access to first-line targeted therapies that could be used if tests were mutation positive were also identified. Respondents identified potential cultural sensitivities related to sending tissue samples abroad for genetic tests that would necessitate clinicians discussing this option with individual patients.

The contradictory effects of timelines on community participation in a health promotion programme.

Timelines are universal features of health promotion programmes, which often receive little in the way of detailed analysis. Prospectively, timelines form supportive structures; they assist in planning and provide key milestones. However, they may also simultaneously constrain action or force the prioritization of some actions over others. This article uses the case of one health promotion programme to explore the multiple timelines in action: the contract, evaluation, usual programme phases and specific to a community garden project in the programme, the seasons. This exploration demonstrates the complexity of these timelines and how they affected programme implementation and were reflected in community participation. The discussion also demonstrates the importance of skilled facilitation of programmes, especially those based on a community development approach.

Barriers to best outcomes in breastfeeding for Maori: mothers' perceptions, whanau perceptions, and services.

This research explores the perceptions of New Zealand Maori women and their whanau (customary Maori extended family) toward barriers to achieving best outcomes in infant feeding: exclusively breastfed infants at 6 months. Interviews are undertaken with 59 Maori women who have given birth in the previous 3 years and 27 whanau members. Although mothers and whanau members feel positively toward breastfeeding and generally expect to breastfeed exclusively, these expectations are unmet in many cases because of lack of support when establishing breastfeeding; lack of support when life circumstances change; lack of timely, culturally relevant, and comprehensible information; confusion about smoking while breastfeeding; uncertainty about the safety of bed-sharing, and perceived lack of acceptability of breastfeeding in public. The relatively high rates of tobacco use by Maori create a tension for breastfeeding mothers, cited by some as a reason for ending breastfeeding prematurely.
