Trends in alcohol-related injury admissions in adolescents in Western Australia and England: population-based cohort study

The association between alcohol retail access and health care visits attributable to alcohol for individuals with and without a history of alcohol-related health-care use

BACKGROUND AND AIMS

Alcohol retail access is associated with alcohol use and related harms. This study measured whether this association differs for people with and without heavy and disordered patterns of alcohol use.

DESIGN

The study used a repeated cross-sectional analysis of health administrative databases.

SETTING, PARTICIPANTS/CASES

All residents of Ontario, Canada aged 10-105 years with universal health coverage (n = 10 677 604 in 2013) were included in the analysis.

MEASUREMENTS

Quarterly rates of emergency department (ED) and outpatient visits attributable to alcohol in 464 geographic regions between 2013 and 2019 were measured. Quarterly off-premises alcohol retail access scores were calculated (average drive to the closest seven stores) for each geographic region. Mixed-effect linear regression models adjusted for area-level socio-demographic covariates were used to examine associations between deciles of alcohol retail access and health-care visits attributable to alcohol. Stratified analyses were run for individuals with and without prior alcohol-attributable health-care use in the past 2 years.

FINDINGS

We included 437 707 ED visits and 505 271 outpatient visits attributable to alcohol. After adjustment, rates of ED visits were 39% higher [rate ratio (RR) = 1.39, 95% confidence interval (CI) = 1.20-1.61] and rates of outpatient visits were 49% higher (RR = 1.49, 95% CI = 1.26-1.75) in the highest versus lowest decile of alcohol access. There was a positive association between alcohol access and outpatient visits attributable to alcohol for individuals without prior health-care attributable to alcohol (RR = 1.65, 95% CI = 1.39-1.95 for the highest to lowest decile of alcohol access) but not for individuals with prior health-care attributable to alcohol (RR = 1.08, 95% CI = 0.90-1.30). There was a positive association between alcohol access and ED visits attributable to alcohol for individuals with and without prior health-care for alcohol for ED visits.

CONCLUSION

In Ontario, Canada, greater alcohol retail access appears to be associated with higher rates of emergency department (ED) and outpatient health-care visits attributable to alcohol. Individuals without prior health-care for alcohol may be more susceptible to greater alcohol retail access for outpatient but not ED visits attributable to alcohol.

Alcohol consumption and health-related quality of life in regional, rural and metropolitan Australia: analysis of cross-sectional data from the Community Health and Rural/Regional Medicine (CHARM) study

BACKGROUND

Relationships between alcohol consumption and health are complex and vary between countries, regions, and genders. Previous research in Australia has focused on estimating the effect of alcohol consumption on mortality. However, little is known about the relationships between alcohol consumption and health-related quality of life (QoL) in Australia. This study aimed to investigate the levels of alcohol intake and QoL in males and females in rural, regional and metropolitan areas of Australia.

METHOD

Participants (n = 1717 Australian adults) completed an online cross-sectional study. Males and females were compared on measures including the AUDIT-C and WHOQOL-BREF. Data were stratified into risk of alcohol use disorder (AUD) and associations were examined between alcohol consumption and QoL, adjusting for sociodemographic variables.

RESULTS

Males had higher alcohol consumption and were at greater risk of AUD than females (20% vs 8%). Relationships between alcohol consumption and QoL were positive or non-significant for low-moderate AUD risk categories and negative in the severe AUD risk category. Males in regional communities reported higher alcohol consumption (AUDIT-C score 6.6 vs 4.1, p < 0.01) than metropolitan areas. Regression analyses identified that after adjusting for sociodemographic variables, alcohol consumption was positively related to overall, environmental, and physical QoL and general health.

CONCLUSION

The results indicate that alcohol consumption is negatively related to QoL only in those with severe risk of AUD. Males in regional areas reported higher alcohol consumption than those in metropolitan areas. These results provide further information about relationships between alcohol intake and health in Australia that can help inform prevention, screening and delivery of interventions.

The hidden impact of alcohol on young victims: an analysis of alcohol-related police offences resulting in hospitalisation

BACKGROUND

Alcohol-related harm (ARH) is a significant public health concern affecting young individuals, particularly those involved in alcohol-related police incidents resulting in hospitalisation. However, the impact of alcohol on young victims remains under researched. This study aimed to identify the characteristics of offenders and victims involved in these incidents, analyse the types of offences, and understand the under-ascertainment of ARH in hospital records.

METHODS

A retrospective longitudinal study of 12-24-year-olds born between 1980 and 2005 was conducted using linked data from hospital admissions, emergency department presentations, and police incident records. Alcohol-related incidents were identified based on the attending officers' opinions in the Western Australia Police's Incident Management System (IMS). Logistic and log-binomial regression were utilised to analyse the factors associated with victimisation and under-ascertainment of ARH.

RESULTS

Our study included 22,747 individuals (11,433 victims and 11,314 offenders) involved in alcohol-related police incidents, with a small majority of victims being female (53%, n = 6,074) and a large majority of offenders being male (84.3%, n = 9,532). Most victims did not receive a diagnosis of ARH (71%, n = 760). Women were 10 times more likely to have been a victim in ARH police incidents and 2 times more likely to have an undiagnosed alcohol-related hospital admission than men. Victims and offenders predominantly came from disadvantaged areas and major cities. Aboriginal individuals were overrepresented as both offenders and victims. A significant proportion of individuals experienced emergency department presentations or hospital admissions, with head injuries being the most common. Assault causing bodily harm was the most prevalent offence resulting in hospitalisation (66%, n = 2,018).

CONCLUSIONS

There is a noteworthy disparity between the quantity of hospital admissions attributed to alcohol-related incidents and the number of cases that are formally classified as ARH in the hospital system. This disparity highlights a more profound issue of substantial under-ascertainment or inadequate identification of ARH than previously acknowledged. Our findings justify the prioritisation of prevention strategies, beyond improvement in the documentation of alcohol-related hospitalisation. Considering the scale of the problem, and the underestimation of the burden of alcohol-related hospitalisation, a proportional increase in investment is necessary to achieve population-level reductions in ARH.

Prevalence and factors associated with serious injuries and aggressive behaviours among in-school adolescents in Panama

Introduction

Injuries during adolescence cause lifelong harm and death. Our study used a nationally representative sample to examine the prevalence and risk factors associated with serious injuries among in-school adolescents in Panama.

Methods

We analysed Panama's 2018 Global School-Based Student Health Survey data using SPSS. Percentages were used to summarise the results of the prevalence of serious injuries. Binomial logistic regression analysis was performed to examine the risk factors of serious injuries. The results were presented as an adjusted odds ratio (AOR) at a 95% confidence interval (CI).

Results

The prevalence of serious injury among in-school adolescents in Panama is 45%. Furthermore, the study found that males (AOR= 1.495, CI=1.272--1.756), truancy (AOR=1.493, CI=1.249--1.785), overweight (AOR= 1.246, 95% CI=11.057--1.469), drinking alcohol (AOR= 1.397, CI=1.151--1.695), experiencing physical attack (AOR= 2.100, CI=11.646--2.681), engaging in a physical fight (AOR=1.586, CI=1.289--1.952) and bullied outside school (AOR=1.276, CI=1.005--1.621) significantly predict serious injuries among adolescents in Panama.

Conclusion

Multidisciplinary approaches targeting the correlates observed will help reduce the high prevalence of serious injuries among in-school adolescents in Panama.

Trends in alcohol-attributable hospitalisations and emergency department visits by age, sex, drinking group and health condition in Ontario, Canada

INTRODUCTION

Alcohol-attributable harms are increasing in Canada. We described trends in alcohol-attributable hospitalisations and emergency department (ED) visits by age, sex, drinking group, attribution and health condition.

METHODS

Hospitalisation and ED visits for partially or wholly alcohol-attributable health conditions by age and sex were obtained from population-based health administrative data for individuals aged 15+ in Ontario, Canada. Population-level alcohol exposure was estimated using per capita alcohol sales and alcohol use data. We estimated the number and rate of alcohol-attributable hospitalisations (2008-2018) and ED visits (2008-2019) using the International Model of Alcohol Harms and Policies (InterMAHP).

RESULTS

Over the study period, the modelled rates of alcohol-attributable health-care encounters were higher in males, but increased faster in females. Specifically, rates of alcohol-attributable hospitalisations and ED visits increased by 300% (19-76 per 100,000) and 37% (774-1,064 per 100,000) in females, compared to 20% (322-386 per 100,000) and 2% (2563-2626 per 100,000) in males, respectively. Alcohol-attributable ED visit rates were highest among individuals aged 15-34, however, increased faster among individuals aged 65+ (females: 266%; males: 44%) than 15-34 years (females:+17%; males: -16%). High-volume drinkers had the highest rates of alcohol-attributable health-care encounters; yet, low-/medium-volume drinkers contributed substantial hospitalisations (11%) and ED visits (36%), with increasing rates of ED visits in females drinking low/medium volumes.

DISCUSSION AND CONCLUSIONS

Alcohol-attributable health-care encounters increased overall, and faster among females, adults aged 65+ and low-/medium-volume drinkers. Monitoring trends across subpopulations is imperative to inform equitable interventions to mitigate alcohol-attributable harms.

Most common principal diagnoses assigned to Australian emergency department presentations involving alcohol use: a multi-centre study

OBJECTIVES

Alcohol is the most widely consumed psychoactive substance in Australia and the consequences of alcohol consumption have enormous personal and social impacts. This study aimed to describe the principal diagnoses of emergency department (ED) presentations involving alcohol use in the previous 12 hours at eight hospitals in Victoria and the Australian Capital Territory, Australia.

METHODS

Twelve months' data (1 July 2018 - 30 June 2019) were collected from eight EDs, including demographics, ICD-10 codes, hospital location and self-reported drinking in the preceding 12 hours. The ten most common ICD-10 discharge codes were analysed based on age, sex and hospital geographic area.

RESULTS

ICD codes pertaining to mental and behavioural disorders due to alcohol use accounted for the highest proportion in most EDs. Suicide ideation/attempt was in the five highest ICD codes for all but one hospital. It was the second most common alcohol-related presentation for both males and females.

CONCLUSIONS

Alcohol plays a major role in a range of presentations, especially in relation to mental health and suicide.

IMPLICATIONS FOR PUBLIC HEALTH

The collection of alcohol involvement in ED presentations represents a major step forward in informing the community about the burden of alcohol on their health resources.

Socioeconomic and Geographic Disparities in Emergency Department Visits due to Alcohol in Ontario: A Retrospective Population-level Study from 2003 to 2017

OBJECTIVE

While the overall health system burden of alcohol is large and increasing in Canada, little is known about how this burden differs by sociodemographic factors. The objectives of this study were to assess sociodemographic patterns and temporal trends in emergency department (ED) visits due to alcohol to identify emerging and at-risk subgroups.

METHODS

We conducted a retrospective population-level cohort study of all individuals aged 10 to 105 living in Ontario, Canada. We identified ED visits due to alcohol between 2003 and 2017 using defined International Classification of Diseases, 10th edition, codes from a pre-existing indicator. We calculated annual age- and sex-standardized, and age- and sex-specific rates of ED visits and compared overall patterns and changes over time between urban and rural settings and income quintiles.

RESULTS

There were 829,662 ED visits due to alcohol over 15 years. Rates of ED visits due to alcohol were greater for individual living in the lowest- compared to the highest-income quintile neighbourhoods, and disparities (rate ratio lowest to highest quintile) increased with age from 1.22 (95% CI, 1.19 to 1.25) in 15- to 18-year-olds to 4.17 (95% CI, 4.07 to 4.28) in 55- to 59-year-olds. Rates of ED visits due to alcohol were significantly greater in rural settings (56.0 per 10,000 individuals, 95% CI, 55.7 to 56.4) compared to urban settings (44.8 per 10,000 individuals, 95% CI, 44.7 to 44.9), particularly for young adults. Increases in rates of visits between 2003 and 2017 were greater in rural versus urban settings (82 vs. 68% increase in age- and sex-standardized rates) and varied across sociodemographic subgroups with the largest annual increases in rates of visits in young (15 to 29) low-income women (6.9%, 95%CI, 6.7 to 7.3) and the smallest increase in older (45 to 59) high-income men (2.7, 95%CI, 2.4 to 3.0).

CONCLUSION

Alcohol harms display unique patterns with the highest burden in rural and lower-income populations. Rural-urban and income-based disparities differ by age and sex and have increased over time, which offers an imperative and opportunity for further interventions by clinicians and policy makers.

Young people with prior health service contacts have increased risk of repeated alcohol-related harm hospitalisations

INTRODUCTION

After a first alcohol-related hospitalisation in youth, subsequent hospitalisations may demonstrate an increased risk of further alcohol-related hospitalisations, but there is no existing data on this.

METHODS

A retrospective longitudinal study between July 1992 and June 2017 using linked hospital administrative data identified 23 464 Western Australian young people [9009 (38.4%) females and 14 455 (61.6%) males], aged 12-24 years hospitalised for at least one alcohol-related harm (ARH) episode of care. Cox regression was used to estimate hazard ratios (HR) between risk factors and repeated alcohol-related hospitalisation after the first discharge for ARH.

RESULTS

Of those admitted for an alcohol-related hospitalisation (n = 23 464), 21% (n = 4996) were readmitted for ARH. This high-risk sub-group comprised 46% (n = 16 017) of the total alcohol-related admissions (n = 34 485). After the first discharge for ARH, 16% (804) of people who experienced an alcohol-related readmission were readmitted within 1 month, and 51.8% (2589) were readmitted within 12 months. At increased risk of readmission were Aboriginal people and those with prior health service contacts occurring before their first alcohol-related hospitalisation, including illicit drug hospitalisations, mental health contacts and, in a sub-analysis, emergency department presentations.

DISCUSSION AND CONCLUSIONS

The probability of a repeated ARH hospitalisation was highest in the first month after initial discharge. There is a high-risk sub-group of young people more likely to have a repeat ARH hospitalisation. This represents an opportunity to provide interventions to those most at risk of repeated ARH.

Trends in Hospital Admissions for Intimate Partner Violence in Australian Mothers With Children Born From 1990 to 2009

This study aims to determine the prevalence, and trends over time, of Western Australian (WA) mothers who were victims of intimate partner violence (IPV) requiring hospital admission. The study investigated the prevalence of all mothers and the specific prevalence of Aboriginal and non-Aboriginal mothers. A population-based cohort study using de-identified linked health data of mothers of children born from 1990 to 2009 in WA was carried out. The prevalence of hospitalizations for IPV in mothers of children born in the period 1990-2009 (per 1,000 births) was calculated. Results indicate that the overall prevalence of hospital admissions for mothers assaulted 12 months prior to their child's birth month increased in the period 1990-2009, from 2.7 to 7.7 per 1,000 births. There was also an increase in the overall prevalence of hospital admissions of mothers who were assaulted 12 months prior to the birth month and 36 months after the birth month, from 8.9 per 1,000 births in 1990 to 19.4 per 1,000 births in 2009. In addition, being Aboriginal, having a mother <30 years of age, and being of low SES significantly increased the odds of having a mother with an IPV admission. This study highlights that while there has been an increase in the prevalence of IPV admissions for mothers of children born from 1990 to 2009 in WA, the level of prevalence has remained persistent for the last decade for the whole population. However, non-Aboriginal mothers have seen an increase in prevalence in the last decade. This increase is associated with the introduction of the Z63.0 code in International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM). This study highlights the importance of prioritizing groups for targeted early intervention and prevention as well as the need for culturally appropriate strategies to reduce the burden of interpersonal violence.

Stronger alcohol-violence association when adolescents drink less? Evidence from three Nordic countries

BACKGROUND

Since 2000, adolescents' alcohol use and heavy episodic drinking (HED) have declined in the Nordic countries. However, little is known about corresponding trends in alcohol-related harm and possible changes in the alcohol-harm association. The aims are to examine (i) whether the decline in HED was accompanied by a decline in alcohol-related violence (AV) and (ii) whether the strength of the HED-AV association changed concomitant with the decline.

METHODS

Analysis of data from the European School Survey Project on Alcohol and Other Drugs (ESPAD), conducted among 15-16-year-olds in Iceland, Norway and Sweden in 2007 and 2015 (n = 17 027). Changes in proportions of AV and alcohol use past 12 months, and mean frequency of HED past 30 days were examined using Pearsons χ2-test and F-test, respectively. The HED-AV associations were estimated using logistic regression analysis.

RESULTS

HED and AV proportions decreased from 2007 to 2015 in all countries. Among current drinkers (n = 8927), both HED frequency and AV proportion decreased in Norway (P < 0.001) and remained stable in Iceland. In Sweden, AV decreased (P < 0.001) whereas HED remained stable. The magnitude of the HED-AV association increased in Norway (Beta2015-2007 = 0.145, 95% CI 0.054-0.236), remained the same in Iceland and decreased in Sweden (Beta2015-2007 = -0.082, 95% CI -0.158 to -0.005).

CONCLUSIONS

Among youth in Iceland, Norway and Sweden, heavy episodic drinking and alcohol-related violence declined from 2007 to 2015. Among drinkers, the strength of the alcohol-violence association was moderated by the extent of heavy episodic drinking.

Rates of emergency department visits attributable to alcohol use in Ontario from 2003 to 2016: a retrospective population-level study

BACKGROUND

Alcohol use causes a large burden on the health of Canadians, and alcohol-related harms appear to be increasing in many high-income countries. We sought to analyze changes in emergency department visits attributable to alcohol use, by sex, age and neighbourhood income over time.

METHODS

All individuals aged 10 to 105 years living in Ontario, Canada, between 2003 and 2016 were included in this study. The primary outcome was age-standardized rates of emergency department visits attributable to alcohol use, defined using diagnostic codes from the Canadian Institute for Health Information Health Indicator "hospitalizations entirely caused by alcohol." We compared rates of these visits using a retrospective population-level design.

RESULTS

Among 15 121 639 individuals, there were 765 346 emergency department visits attributable to alcohol use over the study period. Between 2003 and 2016, the age-standardized rates of these visits increased more in women (86.5%) than in men (53.2%), and the increase in rates of emergency department visits attributable to alcohol use was 4.4 times greater than the increases in the rates of overall emergency department visits. Individuals aged 25-29 years experienced the largest change in the rate of emergency department visits attributable to alcohol use (175%). We found evidence of age-cohort effects, whereby the rate of emergency department visits attributable to alcohol use at age 19 years increased on average by 4.07% (95% confidence interval [CI] 3.71%-4.44%) per year for each cohort born between 1986 and 1999. Individuals in the lowest neighbourhood income quintile had 2.37 (95% CI 2.27-2.49) times the rate of emergency department visits attributable to alcohol use than those in the highest income quintile. This disparity increased slightly over the study period.

INTERPRETATION

Although men and lower-income individuals have the highest burden of emergency department visits attributable to alcohol use, the largest increases in visits have been in women and younger adults. Further research should focus on potential causes of these trends to provide guidance on how to reduce alcohol-related harms.
