Which cost of alcohol? What should we compare it against?

A framework for assessing the potential for a double dividend from a policy-induced reduction in alcohol consumption on the economy

OBJECTIVES

Tax policies targeted at reducing alcohol consumption are typically understood to be associated with economic losses, including in alcohol production and trade sectors. This study sought to determine whether the overall effect of reduced alcohol consumption might be positive once improvements in productivity associated with reduced alcohol-related consumption are considered.

STUDY DESIGN

This study used Computable General Equilibrium economic modelling.

METHODS

An economic modelling framework was developed for Scotland, which considered the fiscal and economic impacts of alcohol taxation and the economy-wide impacts. Simulation of hypothetical alcohol taxes and improvements in labour productivity calibrated on losses due to absenteeism and presenteeism in Scotland in 2017.

RESULTS

The long-run impacts of a five pence increase in taxation alone produce negative economic impacts on jobs and Gross Domestic Product in Scotland (1189 jobs and £71.12 million). These effects are reduced by half - but remain negative - when the revenues from such policy are recycled to the economy through government spending. A small improvement in labour productivity - equivalent to 4.95% of the total productivity gap from absenteeism and presenteeism estimated for Scotland - would be sufficient to turn the economic consequence non-negative.

CONCLUSIONS

The overall macroeconomic impact of policies targeted at alcohol consumption should include consideration of the potential productivity effect and that impact studies that do not include such mechanisms are likely to overstate the negative economic impacts of alcohol policies.

A mixed methods analysis evaluating an alcohol health champion community intervention: How do newly trained champions perceive and understand their training and role?

Globally, alcohol harm is recognised as one of the greatest population risks and reducing alcohol harm is a key priority for the UK Government. The Communities in Charge of Alcohol (CICA) programme took an asset-based approach in training community members across nine areas to become alcohol health champions (AHCs); trained in how to have informal conversations about alcohol and get involved with alcohol licensing. This paper reports on the experiences of AHCs taking part in the training through the analysis of: questionnaires completed pre- and post-training (n = 93) and semi-structured interviews with a purposive sample of five AHCs who had started their role. Questionnaires explored: characteristics of AHCs, perceived importance of community action around alcohol and health, and confidence in undertaking their role. Following training AHCs felt more confident to talk about alcohol harms, give brief advice and get involved in licensing decisions. Interviews explored: AHCs' experiences of the training, barriers and facilitators to the adoption of their role, and how they made sense of their role. Four overarching themes were identified through thematic analysis taking a framework approach: (a) perceptions of AHC training; (b) applying knowledge and skills in the AHC role; (c) barriers and facilitators to undertaking the AHC role; and (d) sustaining the AHC role. Findings highlight the challenges in establishing AHC roles can be overcome by combining the motivation of volunteers with environmental assets in a community setting: the most important personal asset being the confidence to have conversations with people about a sensitive topic, such as alcohol.

Estimating the economic consequences of substance use and substance use disorders

INTRODUCTION

This contribution gives an overview on estimating the economic impact of substance use (SU) and substance use disorders (SUDs) from a societal perspective.

AREAS COVERED

In this Expert Review, we first discuss the scope of the economic costs of SU to society and the methods used to estimate them. In general, cost studies should not be limited to SUDs, but should also include costs related to the consequences of any type of SU to achieve a comprehensive picture of the societal burden. Further, estimating potentially avoidable costs will increase the value of cost studies. Importantly, methodologically sound cost studies shed light on the magnitude of societal problems related to SU and can be used as a reference point to evaluate regulatory policies and other preventive measures. The area of estimating potential economic benefits of SU is understudied and lacks a theoretical and methodological framework.

EXPERT OPINION

Overall, economic studies on the impact of SU and SUDs can strongly contribute to better-informed decision-making in the creation of regulatory and control policies. The least developed area of research refers to a consensus methodology that could be used in studies which compare economic costs to potential economic benefits.

Costing alcohol-related assault in the night-time economy from a societal perspective: The case of Central Sydney

INTRODUCTION

There is a concern in many countries about violence from late-night alcohol sales and appropriate regulatory responses. However, economic losses arising from this activity rarely feature in public debate. Credible estimates are lacking because economic evaluations have not taken a 'societal perspective', costing health, policing and criminal justice outcomes. Our aims were to: (i) develop an analytic model capable of informing cost-benefit analysis of policy changes; and (ii) estimate costs of alcohol-related assault (ARA) in a major city.

METHODS

We employed decision-analytic cohort models of health and judicial consequences of ARA in Sydney, Australia. We constructed two 6-branch decision-analytic models of patient and offender pathways through the health and judicial systems. We produced overall estimates and analysed their sensitivity to key assumptions.

RESULTS

Combining results from a Health model comprising 40 pathways and 137 cost events, and a Justice model comprising 20 pathways and 48 cost events, yielded an overall cost estimate of $85 093 per ARA, of which 64% was health-related, while 36% was justice-related. Estimates were sensitive to values assigned for 'pain, suffering, morbidity and wellbeing', and to costs of incarceration. Health service-related costs accounted for 1.3% of the total.

DISCUSSION AND CONCLUSION

The costs of ARA are significant and dominated by incidents in which a victim does not necessarily receive acute medical care but suffers loss in quality-of-life, and where a perpetrator is processed through the criminal justice system. Being derived transparently, within a theoretical framework, the estimates are adaptable to inform cost-benefit analyses of policy options in Australia and other countries.

Oxidative stress in alcohol-related liver disease

Alcohol consumption is one of the leading causes of the global burden of disease and results in high healthcare and economic costs. Heavy alcohol misuse leads to alcohol-related liver disease, which is responsible for a significant proportion of alcohol-attributable deaths globally. Other than reducing alcohol consumption, there are currently no effective treatments for alcohol-related liver disease. Oxidative stress refers to an imbalance in the production and elimination of reactive oxygen species and antioxidants. It plays important roles in several aspects of alcohol-related liver disease pathogenesis. Here, we review how chronic alcohol use results in oxidative stress through increased metabolism via the cytochrome P450 2E1 system producing reactive oxygen species, acetaldehyde and protein and DNA adducts. These trigger inflammatory signaling pathways within the liver leading to expression of pro-inflammatory mediators causing hepatocyte apoptosis and necrosis. Reactive oxygen species exposure also results in mitochondrial stress within hepatocytes causing structural and functional dysregulation of mitochondria and upregulating apoptotic signaling. There is also evidence that oxidative stress as well as the direct effect of alcohol influences epigenetic regulation. Increased global histone methylation and acetylation and specific histone acetylation inhibits antioxidant responses and promotes expression of key pro-inflammatory genes. This review highlights aspects of the role of oxidative stress in disease pathogenesis that warrant further study including mitochondrial stress and epigenetic regulation. Improved understanding of these processes may identify novel targets for therapy.

Motivation to reduce alcohol consumption and subsequent attempts at reduction and changes in consumption in increasing and higher-risk drinkers in England: a prospective population survey

AIMS

To assess how far motivation to reduce alcohol consumption in increasing and higher-risk drinkers in England predicts self-reported attempts to reduce alcohol consumption and changes in alcohol intake during the following 6 months.

METHODS

This study used self-reported data from 2928 higher-risk drinkers in the Alcohol Toolkit Study (ATS): a series of monthly cross-sectional household surveys of adults aged 16+ years of age in England. Alcohol consumption was measured in an initial survey and in a 6-month telephone follow-up interview using the Alcohol Use Disorders Identification Test (AUDIT)-C questionnaire. Motivation was measured in the initial survey using the Motivation to Reduce Alcohol Consumption (MRAC) scale. Attempts to reduce alcohol consumption during the past 6 months were recorded at follow-up. Data were analysed using repeated-measures difference-in-differences and logistic regression models.

RESULTS

Participants with higher initial motivation to reduce alcohol consumption were more likely to report that they had made an attempt to reduce consumption at follow-up [adjusted odds ratio (ORadj ) = 2.39, 95% confidence interval (CI) = 1.75-3.29]. There was an overall reduction in alcohol consumption between initial survey and follow-up (ORadj  = 0.72, 95% CI = 0.65-0.79), but there was insufficient evidence of an additional effect of motivation to reduce consumption on subsequent changes in alcohol consumption, with the difference-in-differences effect instead suggesting an average increase (ORadj  = 1.37, 95% CI = 1.00-1.88).

CONCLUSIONS

Increasing and higher-risk drinkers in England who report greater motivation to reduce their consumption are more likely to report making an attempt to reduce during the next 6 months, but this may not be associated with a reduction in alcohol consumption.

Implementing a Public Health Objective for Alcohol Premises Licensing in Scotland: A Qualitative Study of Strategies, Values, and Perceptions of Evidence

The public health objective for alcohol premises licensing, established in Scotland in 2005, is unique globally. We explored how public health practitioners engaged with the licensing system following this change, and what helped or hindered their efforts. Semi-structured interviews were conducted with 13 public health actors, audio-recorded, and analysed using an inductive framework approach. Many interviewees viewed the new objective as synonymous with reducing population-level alcohol consumption; however, this view was not always shared by licensing actors, some of whom did not accept public health as a legitimate goal of licensing, or prioritised economic development instead. Some interviewees were surprised that the public health evidence they presented to licensing boards did not result in their hoped-for outcomes; they reported that licensing officials did not always understand or value health data or statistical evidence. While some tried to give "impartial" advice to licensing boards, this was not always easy; others were clear that their role was one of "winning hearts and minds" through relationship-building with licensing actors over time. Notwithstanding the introduction of the public health objective, there remain significant, and political, challenges in orienting local premises licensing boards towards decisions to reduce the availability of alcohol in Scotland.
