Closing the gap in Australian Aboriginal infant immunisation rates -- the development and review of a pre-call strategy

Having a real say: findings from first nations community panels on pandemic influenza vaccine distribution

BACKGROUND

Recent deliberations by Australian public health researchers and practitioners produced an ethical framework of how decisions should be made to distribute pandemic influenza vaccine. The outcome of the deliberations was that the population should be considered in two categories, Level 1 and Level 2, with Level 1 groups being offered access to the pandemic influenza vaccine before other groups. However, the public health researchers and practitioners recognised the importance of making space for public opinion and sought to understand citizens values and preferences, especially First Nations peoples.

METHODS

We conducted First Nations Community Panels in two Australian locations in 2019 to assess First Nations people's informed views through a deliberative process on pandemic influenza vaccination distribution strategies. Panels were asked to make decisions on priority levels, coverage and vaccine doses.

RESULTS

Two panels were conducted with eighteen First Nations participants from a range of ages who were purposively recruited through local community networks. Panels heard presentations from public health experts, cross-examined expert presenters and deliberated on the issues. Both panels agreed that First Nations peoples be assigned Level 1 priority, be offered pandemic influenza vaccination before other groups, and be offered two doses of vaccine. Reasons for this decision included First Nations people's lives, culture and families are important; are at-risk of severe health outcomes; and experience barriers and challenges to accessing safe, quality and culturally appropriate healthcare. We found that communication strategies, utilising and upskilling the First Nations health workforce, and targeted vaccination strategies are important elements in pandemic preparedness and response with First Nations peoples.

CONCLUSIONS

First Nations Community Panels supported prioritising First Nations peoples for pandemic influenza vaccination distribution and offering greater protection by using a two-dose full course to fewer people if there are initial supply limitations, instead of one dose to more people, during the initial phase of the vaccine roll out. The methodology and findings can help inform efforts in planning for future pandemic vaccination strategies for First Nations peoples in Australia.

Exploring the Reported Strengths and Limitations of Aboriginal and Torres Strait Islander Health Research: A Narrative Review of Intervention Studies

High quality intervention research is needed to inform evidence-based practice and policy for Aboriginal and Torres Strait Islander communities. We searched for studies published from 2008-2020 in the PubMed database. A narrative review of intervention literature was conducted, where we identified researcher reported strengths and limitations of their research practice. A total of 240 studies met inclusion criteria which were categorised as evaluations, trials, pilot interventions or implementation studies. Reported strengths included community engagement and partnerships; sample qualities; Aboriginal and Torres Strait Islander involvement in research; culturally appropriate and safe research practice; capacity building efforts; providing resources or reducing costs for services and communities; understanding local culture and context; and appropriate timelines for completion. Reported limitations included difficulties achieving the target sample size; inadequate time; insufficient funding and resources; limited capacity of health workers and services; and inadequate community involvement and communication issues. This review highlights that community consultation and leadership coupled with appropriate time and funding, enables Aboriginal and Torres Strait Islander health intervention research to be conducted. These factors can enable effective intervention research, and consequently can help improve health and wellbeing outcomes for Aboriginal and Torres Strait Islander people.

Development and implementation of a shared governance model in a mainstream health unit: a case study of embedding Aboriginal voices in organisational decision making

This case study focuses on the development and implementation of a governance structure and processes by a mainstream health unit that valued the principles of Aboriginal self-determination, empowerment and leadership by Aboriginal staff in organisational and service delivery decisions and elevated Aboriginal voices by embedding cultural inclusion in such decision making. Various models of embedding Aboriginal voices in the governance of the unit were developed and implemented over time. Ongoing review and reflection identified limitations and opportunities for improving the embedding of Aboriginal voices in organisational decision making. In 2017, Aboriginal staff and senior management implemented a joint governance model for providing strategic leadership of the unit with the objective of enhancing the delivery of culturally appropriate population health services for the benefit of Aboriginal communities. In its 3 years of operation to date, the model has provided strategic oversight of the organisation, implemented several strategic initiatives, including a cultural assessment process, maintaining and strengthening Aboriginal recruitment, monitoring employment vacancies, establishing a wellbeing leadership group, monitoring budget allocation and developing an Aboriginal data management protocol, and has provided additional professional development opportunities for Aboriginal staff. This case study demonstrates the feasibility, importance and benefits of engaging and embedding Aboriginal voices in the governance of a mainstream health service delivery unit, as well as the need for ongoing reflection and improvement. Further translation of the model to the operational levels of the unit is required. The governance model has the potential to be replicated in a tailored manner in other mainstream health units and organisations delivering services to Aboriginal peoples and communities. What is known about the topic? Aboriginal people continue to experience the poorest health outcomes of any population group in Australia. Closing the gap in Aboriginal health requires Aboriginal people to be active and equal participants in all levels of decision making. Governance of mainstream health organisations is predominantly positioned in the Western medical positivist paradigm, which fails to embed Aboriginal voices in organisational and service delivery decision making. What does this paper add? This case study describes the processes taken and the outcomes achieved thus far by a mainstream health service delivery unit developing and implementing a governance model that embedded Aboriginal perspectives in its decision making. It highlights that through commitment and persistence, as well as acknowledging the challenges of working between two worlds, it is possible to reconstruct existing governance models, allowing respectful and meaningful space for Aboriginal people to co-design and co-share the governance of health service delivery. This case study demonstrates the potential of the cultural governance model to be replicated and applied to other mainstream health service delivery units. What are the implications for practitioners? This case study highlights the need for health services to invest in employing and empowering Aboriginal people to co-develop and co-lead a shared approach to organisational governance through processes that are culturally safe, inclusive and appropriate.

Control of vaccine preventable diseases in Australian infants: reviewing a decade of experience with DTPa-HBV-IPV/Hib vaccine

The combined vaccine against diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and Haemophilus influenzae b (DTPa-HBV-IPV/Hib, Infanrix Hexa, GSK) has been used for childhood immunization in Australia according to a two-, four-, six-month schedule since 2009. We reviewed data available in the Australian National Notifiable Diseases Surveillance System, annual vaccination coverage reports, the Database of Adverse Event Notifications, and peer-reviewed literature to assess vaccine coverage rates, incidence of all six vaccine preventable diseases, and the safety profile of DTPa-HBV-IPV/Hib vaccine in Australian infants over a period of ten years of exclusive use. Between 2009 and 2018 vaccine coverage for infants aged 12 months increased from 91.7% to 94.0% and from 84.9% to 92.6% for all and for Indigenous infants, respectively. Over the same time period, there were no reports of poliomyelitis, diphtheria or tetanus in infants <12 months of age. The incidence of hepatitis B among Australian infants <12 months of age remains 10 to 20-fold lower than the national average. Control of Haemophilus influenzae b (Hib) and pertussis disease has continued to be challenging. Timely administration of the primary series, as well as increasing coverage rates, particularly among Indigenous children, has contributed to improvements in Hib and pertussis disease control. The incorporation of additional strategies such as adjustment of the first vaccination encounter to six weeks of age, parental cocooning, and most recently maternal vaccination has further reduced the burden of pertussis, particularly during the first six months of life. The frequency of the ten most common adverse events related to the DTPa-HBV-IPV/Hib vaccine demonstrates an acceptable safety profile. Data collected over ten years of consistent, exclusive use of the DTPa-HBV-IPV/Hib vaccine in Australia highlights combination vaccination as a cornerstone in maintaining infant health.

Improving the accuracy of ACIR data and increasing vaccination rates

Immunisation at the earliest appropriate age and high levels of vaccine coverage at milestone ages are important in preventing the spread of vaccine-preventable diseases. At the Central Coast Public Health Unit, the authors sought to determine if follow-up of children said by the Australian Childhood Immunisation Register (ACIR) to be overdue for vaccination improved both of these factors. In a quality improvement activity, monthly ACIR lists of overdue Central Coast children aged 9 to 10 months of age were examined. The study alternated three months of intervention with three months of no intervention. The intervention was designed to find evidence of vaccination, first from the last known provider, and then if this was unsuccessful, from the parent. If no information was available, a letter was sent to the parents. If the child was indeed vaccinated, the register was updated. If the child was missing any vaccinations, the parent(s) were encouraged to complete the schedule. On reviewing routinely-published quarterly ACIR data at three-monthly intervals for 24 months after the intervention (or non-intervention), timeliness of vaccination improved in the intervention cohort. Central Coast fully vaccinated rates diverged from NSW rates during the study. In addition, the ACIR quarters that contained two out of three months of intervention rather than one out of three months of intervention had the highest rates of fully vaccinated children. The authors concluded that the intervention improved both timeliness of vaccination and the proportion of fully vaccinated children.

Immunisation rates among children in Nuuk

The children immunisation programme in Greenland correlates to the one in Denmark with the addition of the Bacille Calmette-Guerin (BCG)-vaccine and the immunisation against Hepatitis B (HBV). The immunisation rate among children in Greenland has been and is currently unknown and this study aims to estimate the immunisation rates among children in Nuuk from 1 July 2015 until 30 June 2016. We did an observational cross-sectional study based on a statistical extraction identifying all children in Nuuk eligible for an immunization in the children immunisation programme from 1 July 2015 until 30 June 2016 and a review of their medical records. We found acceptable coverage rates among children younger than 12 months, but coverage rates lower than recommended by the World Health Organization (WHO) among older children. Among children between 15 months and 4 years the coverage dropped as low as 33.9 %. Increased awareness of child immunisation rates is suggested including continuously monitoring and adjusting of the organisation of the immunisation programme.

Understanding the structure and processes of primary health care for young indigenous children

ABSTRACT INTRODUCTION Primary health care organisations need to continuously reform to more effectively address current health challenges, particularly for vulnerable populations. There is growing evidence that optimal health service structures are essential for producing positive outcomes. AIM To determine if there is an association between process of care indicators (PoCIs) for important young indigenous child health and social issues and: (i) primary health-care service and child characteristics; and (ii) organisational health service structures. METHODS This was a cross-sectional study of 1554 clinical child health audits and associated system assessments from 74 primary care services from 2012 to 2014. Composite PoCIs were developed for social and emotional wellbeing, child neurodevelopment and anaemia. Crude and adjusted logistic regression models were fitted, clustering for health services. Odds ratios and 95% confidence intervals were derived. RESULTS Overall, 32.0% (449) of records had a social and emotional wellbeing PoCI, 56.6% (791) had an anaemia PoCI and 49.3% (430) had a child neurodevelopment PoCI. Children aged 12–23 months were significantly more likely to receive all PoCIs compared to children aged 24–59 months. For every one point increase in assessment scores for team structure and function (aOR 1.14, 95% CI 1.01–1.27) and care planning (aOR 1.14, 95% CI 1.01–1.29) items, there was a 14% greater odds of a child having an anaemia PoCI. Social and emotional wellbeing and child neurodevelopment PoCIs were not associated with system assessment scores. DISCUSSION Ensuring young indigenous children aged 24–59 months are receiving quality care for important social and health indicators is a priority. Processes of care and organisational systems in primary care services are important for the optimal management of anaemia in indigenous children.

To close the childhood immunization gap, we need a richer understanding of parents' decision-making

Vaccination is widely acknowledged as one of the most successful public health interventions globally and in most high-income countries childhood vaccination coverage rates are moderately high. Yet in many instances, immunisation rates remain below aspirational targets and have shown only modest progress toward those targets in recent years, despite concerted efforts to improve uptake. In part, coverage rates reflect individual parents' vaccination attitudes and decisions and, because vaccination decision-making is complex and context-specific, it remains challenging at individual and community levels to assist parents to make positive decisions. Consequently, in the search for opportunities to improve immunisation coverage, there has been a renewed research focus on parents' decision-making. This review provides an overview of the literature surrounding parents' vaccination decision-making, offering suggestions for where efforts to increase vaccination coverage should be targeted and identifying areas for further research.
