A time series analysis of presentations to Queensland health facilities for alcohol-related conditions, following the increase in 'alcopops' tax

Alcohol-Related Presentations to Emergency Departments on Days with Holidays, Social, and Sporting Events: An Integrative Literature Review

INTRODUCTION

Events, specifically those where excessive alcohol consumption is common, pose a risk to increase alcohol-related presentations to emergency departments (EDs). Limited evidence exists that synthesizes the impact from events on alcohol-related presentations to EDs.

STUDY OBJECTIVE

This integrative review aimed to synthesize the literature regarding the impact events have on alcohol-related presentations to EDs.

METHODS

An integrative literature review methodology was guided by the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA) Guidelines for data collection, and Whittemore and Knafl's framework for data analysis. Information sources used to identify studies were MEDLINE, CINAHL, and EMBASE, last searched May 26, 2021.

RESULTS

In total, 23 articles describing 46 events met criteria for inclusion. There was a noted increase in alcohol-related presentations to EDs from 27 events, decrease from eight events, and no change from 25 events. Public holidays, music festivals, and sporting events resulted in the majority of increased alcohol-related presentations to EDs. Few articles focused on ED length-of-stay (LOS), treatment, and disposition.

CONCLUSION

An increase in the consumption of alcohol from holiday, social, and sporting events pose the risk for an influx of presentations to EDs and as a result may negatively impact departmental flow. Further research examining health service outcomes is required that considers the impact of events from a local, national, and global perspective.

The Association between the Australian Alcopops Tax and National Chlamydia Rates among Young People-an Interrupted Time Series Analysis

A national tax increase, which became known as the "alcopops tax", was introduced in Australia on the 27th April 2008 on ready-to-drink alcoholic beverages, which are consumed predominantly by young people. The affordability of alcohol has been identified as the strongest environmental driver of alcohol consumption, and alcohol consumption is a well-known risk factor in the spread of sexually transmitted infections via its association with sexual risk-taking. We conducted a study to investigate whether there was any association between the introduction of the tax and changes in national chlamydia rates: (i) notification rates (diagnoses per 100,000 population; primary outcome and standard approach in alcohol taxation studies), and (ii) test positivity rates (diagnoses per 100 tests; secondary outcome) among 15-24 and 25-34-year-olds, using interrupted time series analysis. Gender- and age-specific chlamydia trends among those 35 and older were applied as internal control series and gender- and age-specific consumer price index-adjusted per capita income trends were controlled for as independent variables. We hypothesised that the expected negative association between the tax and chlamydia notification rates might be masked due to increasing chlamydia test counts over the observation period (2000 to 2016). We hypothesised that the association between the tax and chlamydia test positivity rates would occur as an immediate level decrease, as a result of a decrease in alcohol consumption, which, in turn, would lead to a decrease in risky sexual behaviour and, hence, chlamydia transmission. None of the gender and age-specific population-based rates indicated a significant immediate or lagged association with the tax. However, we found an immediate decrease in test positivity rates for 25-34-year-old males (27% reduction-equivalent to 11,891 cases prevented post-tax) that remained detectable up to a lag of six months and a decrease at a lag of six months for 15-24-year-old males (31% reduction-equivalent to 16,615 cases prevented) following the tax. For no other gender or age combination did the change in test positivity rates reach significance. This study adds to the evidence base supporting the use of alcohol taxation to reduce health-related harms experienced by young people and offers a novel method for calculating sexually transmitted infection rates for policy evaluation.

A time series analysis of alcohol-related presentations to emergency departments in Queensland following the increase in alcopops tax

BACKGROUND

Raising duty on alcohol across the board can reduce morbidity, mortality and other adverse consequences of alcohol use. However, effectiveness is less certain for measures that target specific types of alcohol beverage in isolation. One example from Australia was the increase in tax on alcopops favoured by young people to curb risky drinking in this demographic.

METHODS

We measured alcohol-related health harms in 15-29-year-olds presenting to emergency departments (EDs) in Queensland following the tax increase. These presentations were compared with following ED controls: (1) 15-29-year-olds with asthma or appendicitis; and (2) 30-49-year-olds presenting with alcohol-related harms. We analysed data over a 5-year period (April 2005-April 2010) using a time series analysis. This covered 3 years before, and 2 years after, the tax increase. We investigated both mental and behavioural consequences (F10 codes), and intentional/unintentional injuries (S and T codes).

RESULTS

We fitted an ARIMA (autoregressive integrated moving average) model to test for a change following the increased 'alcopops' tax in April 2008. There was no significant decrease in alcohol-related ED presentations in 15-29-year-olds compared to any of the controls. We found similar results for males and females, narrow and broad definitions of alcohol-related harms, under-19s and ED presentations at night-time and weekends.

CONCLUSIONS

The increase in tax on 'alcopops' did not result in any reduction in alcohol-related harms in this population. Targeting particular alcoholic drinks may therefore not be as effective as more comprehensive policies such as minimum unit pricing for alcohol.

Alcopops, taxation and harm: a segmented time series analysis of emergency department presentations

Background

In Australia, a Goods and Services Tax (GST) introduced in 2000 led to a decline in the price of ready-to-drink (RTD) beverages relative to other alcohol products. The 2008 RTD (“alcopops”) tax increased RTD prices. The objective of this study was to estimate the change in incidence of Emergency Department (ED) presentations for acute alcohol problems associated with each tax.

Methods

Segmented regression analyses were performed on age and sex-specific time series of monthly presentation rates for acute alcohol problems to 39 hospital emergency departments across New South Wales, Australia over 15 years, 1997 to 2011. Indicator variables represented the introduction of each tax. Retail liquor turnover controlled for large-scale economic factors such as the global financial crisis that may have influenced demand. Under-age (15–17 years) and legal age (18 years and over) drinkers were included.

Results

The GST was associated with a statistically significant increase in ED presentations for acute alcohol problems among 18–24 year old females (0 · 14/100 000/month, 95% CI 0 · 05-0 · 22). The subsequent alcopops tax was associated with a statistically significant decrease in males 15–50 years, and females 15–65 years, particularly in 18–24 year old females (−0 · 37/100 000/month, 95% CI −0 · 45 to −0 · 29). An increase in retail turnover of liquor was positively and statistically significantly associated with ED presentations for acute alcohol problems across all age and sex strata.

Conclusions

Reduced tax on RTDs was associated with increasing ED presentations for acute alcohol problems among young women. The alcopops tax was associated with declining presentations in young to middle-aged persons of both sexes, including under-age drinkers.
