Global systematic review of the cost-effectiveness of indigenous health interventions

Abstract Background Indigenous populations around the world have consistently been shown to bear a greater burden of disease, death and disability than their non-Indigenous counterparts. Despite this, little is known about what constitutes cost-effective interventions in these groups. The objective of this paper was to assess the global cost-effectiveness literature in Indigenous health to identify characteristics of successful and unsuccessful interventions and highlight areas for further research. Methods and Findings A systematic review of the published literature was carried out. MEDLINE, PSYCINFO, ECONLIT, EMBASE and CINAHL were searched with terms to identify cost-effectiveness evaluations of interventions in Indigenous populations around the world. The WHO definition was followed in identifying Indigenous populations. 19 studies reporting on 27 interventions were included in the review. The majority of studies came from high-income nations with only two studies of interventions in low and middle-income nations. 22 of the 27 interventions included in the analysis were found to be cost-effective or cost-saving by the respective studies. There were only two studies that focused on Indigenous communities in urban areas, neither of which was found to be cost-effective. There was little attention paid to Indigenous conceptions of health in included studies. Of the 27 included studies, 23 were interventions that specifically targeted Indigenous populations. Outreach programs were shown to be consistently cost-effective. Conclusion The comprehensive review found only a small number of studies examining the cost-effectiveness of interventions into Indigenous communities around the world. Given the persistent disparities in health outcomes faced by these populations and commitments from governments around the world to improving these outcomes, it is an area where the health economics and public health fields can play an important role in improving the health of millions of people.

The health-related quality of life of Indigenous populations: a global systematic review

PurposeIndigenous conceptions of health have been shown to differ from that of their non-Indigenous counterparts. As a result, there remains uncertainty over the appropriateness and value of using existing health-related quality-of-life (HRQoL) instruments in Indigenous communities. The objective of this review was to identify studies that either measure the HRQoL of an Indigenous population or validated a measure used to elicit the HRQoL in an Indigenous population.MethodsA systematic review of the published literature was conducted to (1) investigate the extent to which HRQoL instruments are used in Indigenous populations; (2) to identify which instruments have been validated in which populations; and (3) to identify which instruments have been tailored for use with Indigenous populations.ResultsForty-one studies were included in the review. Only three of the 41 studies utilised Indigenous-specific instruments. The remainder (38 studies) utilised generic population or disease-specific instruments. Four studies found specific HRQoL instruments to be valid in these populations and 32 estimated the HRQoL of an Indigenous population. The limited examples of Indigenous-specific instruments highlighted the potential importance to the HRQoL of these populations of domains that lie outside of traditional measures including social and community domains as well as domains relating to culture, diet and land use on top of more traditional HRQoL domains.ConclusionEnsuring that the HRQoL of Indigenous populations is being appropriately measured is vital to prioritising available resources to the most effective interventions. HRQoL instruments present an opportunity to directly elicit and incorporate Indigenous preferences and conceptions of health into these decisions. Further work is required in the field to ensure that this potential is realised.

Global systematic review of Indigenous community-led legal interventions to control alcohol

Objectives The national and subnational governments of most developed nations have adopted cost-effective regulatory and legislative controls over alcohol supply and consumption with great success. However, there has been a lack of scrutiny of the effectiveness and appropriateness of these laws in shaping the health-related behaviours of Indigenous communities, who disproportionately experience alcohol-related harm. Further, such controls imposed unilaterally without Indigenous consultation have often been discriminatory and harmful in practice. Setting, participants and outcome measures In this systematic review of quantitative evaluations of Indigenous-led alcohol controls, we aim to investigate how regulatory responses have been developed and implemented by Indigenous communities worldwide, and evaluate their effectiveness in improving health and social outcomes. We included articles from electronic databases MEDLINE, EMBASE, CINAHL, PsycINFO and Web of Science from inception to December 2015. Results Our search yielded 1489 articles from which 18 met the inclusion criteria. Controls were implemented in rural and remote populations of high-income nations. Communities employed a range of regulatory options including alcohol rationing, prohibition of sale, importation or possession, restrictions on liquor sold, times of sale or mode of sale, Indigenous-controlled liquor licensing, sin tax and traditional forms of control. 11 studies reported interventions that were effective in reducing crime, injury deaths, injury, hospitalisations or lowering per capita consumption. In six studies interventions were found to be ineffective or harmful. The results were inconclusive in one. Conclusions Indigenous-led policies that are developed or implemented by communities can be effective in improving health and social outcomes.

What are patients’ care experience priorities?

We are investing considerable resources in defining and measuring patients’ care expectations. Such measurement will yield insight into whether and how services are meeting patients’ experience expectations. But because measurement is inherently distanced in time and space, it does not resolve patients’ experience of feeling ‘reluctant to directly challenge healthcare professionals’1 about issues that matter to them now and which may make them feel unsafe. Research has shown that when patients and family members experience concerns about their care, they want to be able to discuss these experiences with their clinicians. They often want such discussions to include explanations from professionals and dialogue about ‘what happened’ and about tensions, uncertainties and contradictions.2 Patients and family members interviewed for a large incident disclosure study reported that they appreciated that care is complex,3 and that there may be no simple answers to explain care problems.4 But being granted the time for dialogue with their clinicians and service representatives reassured patients and family members that their concerns and questions were taken seriously. This meant for them in turn that similar events might be prevented from happening again. They also felt that dialogue reassured them that their views on and advice about how to improve care were respected. When patients have concerns about their care, the timing and authenticity of such dialogue are seen as paramount. For its part, measuring patients’ experiences presupposes abstracting ‘what happened to you’ into a general metric that applies to ‘people like you’. Measurement is, in the first instance, about the service and the system. Dialogue is about the patient and their family. Measurement will never obviate patients’ providing feedback about their concerns to their own clinicians and their local services. What started out as satisfaction surveying in the 1970s5 has now morphed into …

Judicial intervention in alcohol regulation: an empirical legal analysis.

Objective: While governments draft law and policy to promote public health, it is through cases put before the judiciary that the implementation of law can be challenged and where its practical implications are typically determined. In this paper, we examine the role of court judgements on efforts in Australia to regulate the harmful use of alcohol.

Participant preferences for an Aboriginal-specific fall prevention program: Measuring the value of culturally-appropriate care

Background Culturally-specific services are central to efforts to improve the health of Aboriginal Australians. Few empirical studies have demonstrated the value of such services relative to mainstream alternatives. Objective To assess the preferences and willingness to pay (WTP) of participants for attending a class and the relative importance of transport, cost and cultural-appropriateness in the choices made by participants. Design A discrete choice experiment (DCE) was conducted alongside a study of a culturally-specific fall-prevention service. Attributes that were assessed were out-of-pocket costs, whether transport was provided and whether the class was Aboriginal-specific. Choices of participants were modelled using panel-mixed logit methods. Results 60 patients completed the DCE. Attending a service was strongly preferred over no service (selected 99% of the time). Assuming equivalent efficacy of fall-prevention programs, participants indicated a preference for services that were culturally-specific (OR 1.25 95% CI: 1.00–1.55) and incurred lower out-of-pocket participant costs (OR 1.19 95% CI 1.11–1.27). The provision of transport did not have a statistically significant influence on service choice (p = 0.57). Discussion and conclusions This represents the first published DCE in the health field examining preferences amongst an Aboriginal population. The results empirically demonstrate the value of the culturally-specific element of a program has to this cohort and the potential that stated-preference methods can have in incorporating the preferences of Aboriginal Australians and valuing cultural components of health services. Note on terminology As the majority of the NSW Aboriginal and Torres Strait Islander population is Aboriginal (97.2%), this population will be referred to as ‘Aboriginal’ in this manuscript.

Generating sustainable collective action: Models of community control and governance of alcohol supply in Indigenous minority populations

Restrictions on the supply of alcohol are amongst the most effective and cost effective interventions to address harmful use. However, despite international human rights bodies recognising that self determination must be pre-eminent in efforts to improve Indigenous health, little is known about the role of Indigenous communities in designing and implementing alcohol controls as well as the degree to which government resourcing and/or regulation is utilised. This commentary explores Australian examples of the governance models used to ensure Indigenous participation and leadership when developing regulatory interventions for alcohol control within communities. We identify four models of Indigenous governance: alcohol control interventions that were community conceived and implemented, government-facilitated community-led, community coalitions backed by government intervention and government initiated community partnerships. Each model is underpinned by specific governance arrangements which incorporate rules and processes that determine authority, accountability and Indigenous participation in decision-making. The aim of this paper is to benchmark these models of governance along a spectrum of community engagement beginning with forms of non-participation and ending with full citizen control. In addition, we put forward recommendations for governments at all levels to facilitate culturally acceptable and robust models of Indigenous governance that have the potential to improve health and social outcomes.
