Hazardous and harmful alcohol use in the Northern Territory, Australia: the impact of alcohol policy on critical care admissions using an extended sampling period

Alcohol-related injury hospitalisations in relation to alcohol policy changes, Northern Territory, Australia, 2007-2022: A joinpoint regression analysis

INTRODUCTION

The Northern Territory (NT) of Australia has the highest rates of alcohol consumption and injury in the country. We aimed to: (i) describe the epidemiology of alcohol-related injury (ARI) hospitalisations in the NT; (ii) estimate the proportion of alcohol involvement in injury hospitalisations; and (iii) consider the influence of alcohol policies on ARI hospitalisation trends.

METHODS

We conducted a retrospective time-series study using coded hospitalisation data from NT public hospitals between 2007 and 2022. ARI hospitalisation was defined combining indicators for injury and acute alcohol use. We undertook descriptive analyses and calculated alcohol involvement against all injury hospitalisations. Annual percent changes (APC) were computed using joinpoint regression to examine the influence of alcohol policies on ARI hospitalisation trends by NT geographical regions (Central Australia and Top End).

RESULTS

Alcohol use was associated with 22.6% of all injury hospitalisations. The most common cause of ARI hospitalisations was assault (46%). In Central Australia, a significant trend decline (APC -12.2; p = 0.011) was observed after 2017 following alcohol policies implemented between 2017 and 2018 (Banned Drinkers Register v2; Minimum Unit Price; and Police Auxiliary Liquor Inspectors). Consecutive years with the greatest decrease in Central Australia were 2013-2014 (APC -25.8) and 2018-2019 (APC -35.1); likely influenced by alcohol policies in effect at the time. In the Top End, a non-significant trend decline (APC -26.1; p = 0.186) was observed after 2020.

DISCUSSION AND CONCLUSIONS

Alcohol policies implemented between 2017 and 2018 were associated with reduced ARI hospitalisations in Central Australia. Alcohol policies that demonstrated reduced harm should be sustained.

What are the impacts of alcohol supply reduction measures on police-recorded adult domestic and family violence in the Northern Territory of Australia?

BACKGROUND

During 2017-18, the Northern Territory (NT) introduced a Banned Drinker Register (BDR) and Minimum Unit Price (MUP) NT-wide; Police Auxiliary Liquor Inspectors (PALIs) in three regional towns; and restrictions on daily purchases/opening hours (DPOH) in one regional town. The BDR is an individual-level alcohol ban; MUP is a pricing policy; and PALIs enforce bans on restricted areas at takeaway outlets. This study examines the impact of these policies on adult domestic and family violence (DFV).

METHODS

We examined DFV assaults and breaches of violence orders from January 2014 - February 2020 using interrupted time series models for NT, Greater Darwin, Katherine, Tennant Creek, and Alice Springs. To account for increasing numbers of individuals on the BDR we tested two timepoints (Sept 2017, March 2018).

FINDINGS

Following DPOH, assaults (78 %) and alcohol-involved assaults (92 %) decreased in Tennant Creek. After PALIs, assaults (79 %) in Tennant Creek, and breaches (39 %) and alcohol-involved breaches (58 %) in Katherine decreased. After MUP, assaults (11 %), alcohol-involved assaults (21 %) and alcohol-involved breaches (21%) decreased NT wide. After MUP/PALIs in Alice Springs, alcohol-involved assaults (33 %), breaches (42 %), and alcohol-involved breaches (57 %) decreased. BDR (Sept 2017) found increases in assaults (44 %) and alcohol-involved assaults (39 %) in Katherine and assaults (10%) and alcohol-involved assaults NT-wide (17 %). There were increases of 21 %-45 % in breaches NT-wide, in Darwin, Katherine, and Alice Springs. Following March 2018 found increases in assaults (33 %) and alcohol-involved assaults (48 %) in Katherine. There were increases - from 20 % to 56 % - in breaches in NT-wide, Katherine, and Alice Springs.

CONCLUSION

PALIs and DPOH were associated with some reductions in DFV; the BDR was associated with some increases. The upward trend commences prior to the BDR, so it is also plausible that the BDR had no effect on DFV outcomes. Although MUP was associated with reductions in the NT-wide model, there were no changes in sites without cooccurring PALIs.

The impact of minimum unit pricing on traumatic brain injury in Scotland: a retrospective cohort study of routine national data

BACKGROUND

Traumatic brain injury (TBI) is a common cause of disability and mortality and is associated with alcohol consumption. On 1st May 2018, the Scottish Government introduced Minimum Unit Pricing (MUP) legislation which set the floor price at which alcohol can be sold to 50 pence per unit. While MUP has led to a 7.6% decrease in off trade alcohol purchases, there are limited studies investigating the clinical impact of this legislation. This study aims to explore the impact of MUP on traumatic brain injury in Scotland.

METHODS

Retrospective cohort study using routinely collected national data collated by the Scottish Trauma Audit Group. Data were requested for all TBI incidents from 1st May to 31st December for both 2017 and 2018. Primary outcome was alcohol-related TBI. Secondary outcomes were injury mechanism, injury severity, clinical course, and short-term mortality. Analysis was conducted using multiple regression models adjusted for age, sex, season, and deprivation.

RESULTS

A total of 1166 patients (66% male, and 46% in the 60-79-year bracket) were identified. Alcohol-related TBI was evident in 184 of 509 (36%) patients before MUP and in 239 of 657 (36%) patients injured after its implementation (p = 0.638). Further, there was no change in injury mechanism, injury severity, hospital course and short-term mortality of TBI after MUP.

CONCLUSIONS

MUP has not resulted in a change in alcohol-related TBI nor in the mechanism and severity of TBI. Limitations in two-point analysis mean that findings should be interpreted with caution and further studies investigating the clinical outcomes of MUP must be conducted.

Views on minimum unit pricing for alcohol before its introduction among people with alcohol dependence in Scotland: A qualitative interview study

INTRODUCTION

Scotland implemented a minimum price per unit of alcohol (MUP) of £0.50 in May 2018 (1 UK unit = 10 mL/8 g ethanol). Some stakeholders expressed concerns about the policy having potential negative consequences for people with alcohol dependence. This study aimed to investigate anticipated impacts of MUP on people presenting to alcohol treatment services in Scotland before policy implementation.

METHODS

Qualitative interviews were conducted with 21 people with alcohol dependence accessing alcohol treatment services in Scotland between November 2017 and April 2018. Interviews examined respondents' current and anticipated patterns of drinking and spending, effects on their personal life, and their views on potential policy impact. Interview data were thematically analysed using a constant comparison method.

RESULTS

Three key themes were identified: (i) strategies used to manage the cost of alcohol and anticipated responses to MUP; (ii) broader effects of MUP; and (iii) awareness and preparedness for MUP. Respondents expected to be impacted by MUP, particularly those on low incomes and those with more severe dependence symptoms. They anticipated using familiar strategies including borrowing and reprioritising spending to keep alcohol affordable. Some respondents anticipated negative consequences. Respondents were sceptical about the short-term benefits of MUP for current drinkers but felt it might prevent harm for future generations. Respondents had concerns about the capacity of treatment services to meet support needs.

DISCUSSION AND CONCLUSIONS

People with alcohol dependence identified immediate concerns alongside potential long-term benefits of MUP before its introduction. They also had concerns over the preparedness of service providers.

'A recipe for cultural disaster!'- a case study of Woolworths Group's proposal to build an alcohol megastore in Darwin, Northern Territory

BACKGROUND

The health and wellbeing impacts of commercial activity on Indigenous populations is an emerging field of research. The alcohol industry is a key driver of health and social harms within Australia. In 2016 Woolworths, the largest food and beverage retailer in Australia, proposed to build a Dan Murphy's alcohol megastore in Darwin, near three 'dry' Aboriginal communities. This study examines the tactics used by Woolworths to advance the Dan Murphy's proposal and understand how civil society action can overcome powerful commercial interests to protect Aboriginal and Torres Strait Islander health and wellbeing.

METHODS

Data from 11 interviews with Aboriginal and non-Aboriginal informants were combined with data extracted from media articles and government, non-government and industry documents. Thematic analysis was informed by an adapted corporate health impact assessment framework.

RESULTS

Woolworths employed several strategies including lobbying, political pressure, litigation, and divisive public rhetoric, while ignoring the evidence suggesting the store would increase alcohol-related harm. The advocacy campaign against the proposal highlighted the importance of Aboriginal and non-Aboriginal groups working together to counter commercial interests and the need to champion Aboriginal leadership. Advocacy strategies included elevating the voices of community Elders in the media and corporate activism via Woolworths' investors.

CONCLUSIONS

The strategies used by the coalition of Aboriginal and non-Aboriginal groups may be useful in future advocacy campaigns to safeguard Aboriginal and Torres Strait Islander health and wellbeing from commercial interests.

The impact of alcohol minimum unit pricing on people with experience of homelessness: Qualitative study

BACKGROUND

Alcohol Minimum Unit Pricing (MUP) was introduced in Scotland in May 2018. Existing evidence suggests MUP can reduce alcohol consumption in the general population, but there is little research about its impact on vulnerable groups. This qualitative study explored experiences of MUP among people with experience of homelessness.

METHODS

We conducted qualitative semi-structured interviews with a purposive sample of 46 people with current or recent experience of homelessness who were current drinkers when MUP was introduced. Participants (30 men and 16 women) were aged 21 to 73 years. Interviews focused on views and experiences of MUP. Data were analysed using thematic analysis.

RESULTS

People with experience of homelessness were aware of MUP but it was accorded low priority in their hierarchy of concerns. Reported impacts varied. Some participants reduced their drinking, or moved away from drinking strong white cider, in line with policy intentions. Others were unaffected because the cost of their preferred drink (usually wine, vodka or beer) did not change substantially. A minority reported increased involvement in begging. Wider personal, relational and social factors also played an important role in responses to MUP.

CONCLUSION

This is the first qualitative study to provide a detailed exploration of the impact of MUP among people with experience of homelessness. Our findings suggest that MUP worked as intended for some people with experience of homelessness, while a minority reported negative consequences. Our findings are of international significance to policymakers, emphasising the need to consider the impact of population level health policies on marginalised groups and the wider contextual factors that affect responses to policies within these groups. It is important to invest further in secure housing and appropriate support services and to implement and evaluate harm reduction initiatives such as managed alcohol programmes.

Thirty years of ANZICS CORE: A clinical quality success story

In 2023, the Australian and New Zealand Intensive Care Society (ANZICS) Registry run by the Centre for Outcomes and Resources Evaluation (CORE) turns 30 years old. It began with the Adult Patient Database, the Australian and New Zealand Paediatric Intensive Care Registry, and the Critical Care Resources Registry, and it now includes Central Line Associated Bloodstream Infections Registry, the Extra-Corporeal Membrane Oxygenation Database, and the Critical Health Resources Information System. The ANZICS Registry provides comparative case-mix reports, risk-adjusted clinical outcomes, process measures, and quality of care indicators to over 200 intensive care units describing more than 200 000 adult and paediatric admissions annually. The ANZICS CORE outlier management program has been a major contributor to the improved patient outcomes and provided significant cost savings to the healthcare sector. Over 200 peer-reviewed papers have been published using ANZICS Registry data. The ANZICS Registry was a vital source of information during the COVID-19 pandemic. Upcoming developments include reporting of long-term survival and patient-reported outcome and experience measures.

Impact of minimum unit pricing on alcohol-related hospital outcomes: systematic review

OBJECTIVE

To determine the impact of minimum unit pricing (MUP) on the primary outcome of alcohol-related hospitalisation, and secondary outcomes of length of stay, hospital mortality and alcohol-related liver disease in hospital.

DESIGN

Databases MEDLINE, Embase, Scopus, APA Psycinfo, CINAHL Plus and Cochrane Reviews were searched from 1 January 2011 to 11 November 2022. Inclusion criteria were studies evaluating the impact of minimum pricing policies, and we excluded non-minimum pricing policies or studies without alcohol-related hospital outcomes. The Effective Public Health Practice Project tool was used to assess risk of bias, and the Bradford Hill Criteria were used to infer causality for outcome measures.

SETTING

MUP sets a legally required floor price per unit of alcohol and is estimated to reduce alcohol-attributable healthcare burden.

PARTICIPANT

All studies meeting inclusion criteria from any country INTERVENTION: Minimum pricing policy of alcohol PRIMARY AND SECONDARY OUTCOME MEASURES: RESULTS: 22 studies met inclusion criteria; 6 natural experiments and 16 modelling studies. Countries included Australia, Canada, England, Northern Ireland, Ireland, Scotland, South Africa and Wales. Modelling studies estimated that MUP could reduce alcohol-related admissions by 3%-10% annually and the majority of real-world studies demonstrated that acute alcohol-related admissions responded immediately and reduced by 2%-9%, and chronic alcohol-related admissions lagged by 2-3 years and reduced by 4%-9% annually. Minimum pricing could target the heaviest consumers from the most deprived groups who tend to be at greatest risk of alcohol harms, and in so doing has the potential to reduce health inequalities. Using the Bradford Hill Criteria, we inferred a 'moderate-to-strong' causal link that MUP could reduce alcohol-related hospitalisation.

CONCLUSIONS

Natural studies were consistent with minimum pricing modelling studies and showed that this policy could reduce alcohol-related hospitalisation and health inequalities.

A historical overview of legislated alcohol policy in the Northern Territory of Australia: 1979-2021

BACKGROUND

The Northern Territory (NT) has the highest levels of alcohol consumption and harms in Australia. Since the creation of the NT Liquor Act 1978, which came into effect in 1979, numerous legislated alcohol policies have been introduced to attempt to address these harms. We present a narrative historical overview of alcohol policies implemented in the NT from 1979 to 2021.

METHODS

Using scoping review methodology, databases were searched from 1979 to 2021. Of 506 articles screened, 34 met inclusion criteria. Reference lists of all included articles were searched, resulting in the inclusion of another 41 articles and reports, totalling 75 final documents. Policies were organised using Babor and colleagues (2010) established framework: 1. pricing/ taxation; 2. regulating physical availability; 3. modifying drinking environments; 4. drink-driving countermeasures; 5. restrictions on marketing; 6. education/persuasion; 7. treatment/early intervention.

RESULTS

Two pricing/taxation policies have been implemented, Living With Alcohol (LWA) and Minimum Unit Price, both demonstrating evidence of positive effects on health and consumption outcomes. Eight policies approaches have focused on regulating physical availability, implemented at both individual and local area levels. Several of these policies have varied by location and been amended over time. There is some evidence demonstrating reduction in harms attributable to Liquor Supply Plans, localised restrictions, and General Restricted Areas, although these have been site specific. Of the three policies which targeted modifying the drinking environment; one was evaluated, finding a relocation of social harms, rather than a reduction. The literature outlines a range of controversies, particularly regarding policies in domain 2-3, including racial discrimination and a lack of policy stability. No policies relating to restricting marketing or education/persuasion programs were found. The only drink-driving legislated policy was considered to have contributed to the success of the LWA program. Three policies relating to treatment were described; two were not evaluated and evidence showed no ongoing benefits of Alcohol Mandatory Treatment.

DISCUSSION

The NT has implemented a large number of alcohol policies, several of which have evidence of positive effects. However, these policies have often existed in a context of clear politicisation of alcohol policy, frequently with an implicit focus on Aboriginal people's consumption.
