Queensland Alcohol-related violence and Night Time Economy Monitoring project (QUANTEM): a study protocol.

BACKGROUND: Alcohol-related harm is a substantial burden on the community in Australia and internationally, particularly harm related to risky drinking practices of young people in the night-time economy. This protocol paper describes a study that will report on the changes in a wide range of health and justice outcome measures associated with major policy changes in the state of Queensland, Australia. A key element includes trading hours restrictions for licensed premises to 2 am for the state and 3 am in Safe Night Precincts (SNPs). Other measures introduced include drinks restrictions after midnight, increased patron banning measures for repeat offenders, mandatory ID scanning of patrons in late-night venues, and education campaigns. METHODS: The primary aim of the study is to evaluate change in the levels of harm due to these policy changes using administrative data (e.g., police, hospital, ambulance, and court data). Other study elements will investigate the impact of the Policy by measuring foot traffic volume in SNPs, using ID scanner data to quantify the volume of people entering venues and measure the effectiveness of banning notices, using patron interviews to quantify the levels of pre-drinking, intoxication and illicit drug use within night-time economy districts, and to explore the impacts of the Policy on business and live music, and costs to the community. DISCUSSION: The information gathered through this project aims to evaluate the effectiveness of the Policy and to draw on these findings to inform future prevention and enforcement approaches by policy makers, police, and venue staff.

Characteristics of individuals presenting to treatment for primary alcohol problems versus other drug problems in the Australian patient pathways study.

BACKGROUND: People seeking treatment for substance use disorders often have additional health and social issues. Although individuals presenting with alcohol as the primary drug of concern (PDOC) account for nearly half of all treatment episodes to the Australian alcohol and other drug (AOD) service system, previous treatment cohort studies have focused only on the profile of Australian heroin or methamphetamine users. While studies overseas indicate that clients seeking treatment primarily for their drinking are less likely to experience social and economic marginalisation than those seeking treatment primarily for illicit or pharmaceutical drug use, very little research has directly compared individuals presenting with alcohol as the PDOC to those primarily presenting with other drugs as their PDOC. METHODS: Seven hundred and ninety-six participants were recruited at entry to specialist AOD treatment in Victoria and Western Australia, and completed measures of demographic and social factors, substance use, quality of life, service use, and criminal justice involvement. We compared those with alcohol as their PDOC to those with other drugs as their PDOC using Pearson chi-square and Mann-Whitney U tests. RESULTS: Rates of social disadvantage, poor quality of life, high severity of substance dependence, and past-year AOD, mental health, acute health, and social service use were high in all groups. However, participants with alcohol as the PDOC were older; more likely to have an educational qualification; less likely to report criminal justice involvement, housing/homelessness service use, tobacco smoking, or problems with multiple substances; and reported better environmental quality of life; but were more likely to have used ambulance services, than those with other drugs as their PDOC. CONCLUSIONS: While those seeking treatment primarily for alcohol problems appear less likely to suffer some forms of social and economic disadvantage or to use multiple substances than those with a primary drug problem, they experience similarly high levels of substance dependence severity and mental health and AOD service use. These findings reinforce the need for AOD services to integrate or coordinate care with programs that address the many complexities clients frequently present with, while also acknowledging differences between those seeking treatment for alcohol versus other drug problems.

Pre-Drinking Behavior of Young Heavy Drinkers.

BACKGROUND: Pre-drinking has been linked to subsequent heavy drinking and the engagement in multiple risky behaviors. OBJECTIVES: The present study examined a group of adolescents who recently had a "big night out" to determine whether there were differences in their pre-drinking behavior based on age, gender, geographic location, and social setting. METHODS: Participants (n = 351, aged 16-19) representing the heaviest 20-25% of drinkers in their age group were recruited using nonrandom sampling from metropolitan (Melbourne, Sydney, Perth) or regional (Bunbury) locations across Australia and administered a survey by a trained interviewer. RESULTS: Almost half the sample pre-drank (n = 149), most commonly at a friend's house. Those aged 18-19 were more likely to pre-drink, and did so at higher quantities compared to their younger counterparts. Males and females reported similar pre-drinking duration, quantity and amount spent on alcohol. Compared to those in cities, regional participants consumed greater quantities over longer periods of time. Two-thirds of participants consumed alcohol in excess of national guidelines during their pre-drinking session. These participants were more likely to nominate price as a motivation to pre-drink and were less likely to report that someone else provided them alcohol. CONCLUSIONS: This study sheds light on the pre-drinking habits of a population of young risky drinkers, and highlights the need for policy makers to address this form of drinking to reduce alcohol-related harm among young people.

An Examination of the Prevalence, Consumer Profiles, and Patterns of Energy Drink Use, With and Without Alcohol, in Australia.

BACKGROUND: There has been a significant growth in the energy drink (ED) market in Australia and around the world; however, most research investigating the popularity of ED and alcohol and energy drink (AED) use has focused on specific subpopulations such as university students. The aim of this study was to estimate the prevalence, consumption patterns, and sociodemographic correlates of ED and combined AED use among a representative Australian population sample. METHODS: A computer-assisted telephone interview survey (n = 2,000) was undertaken in March-April 2013 of persons aged 18 years and over. Half of the interviews were obtained through randomly generated landline telephone numbers and half through mobile phones. Approximately half of the sample was female (55.5%; n = 1,110) and the mean age of participants was 45.9 (range 18 to 95, SD 20.0). RESULTS: Less than 1 in 6 Australians reported ED use (13.4%, n = 268) and 4.6% (n = 91) reported AED use in the past 3 months. Majority of ED and AED users consumed these beverages monthly or less. ED and AED users are more likely to be aged 18 to 24 years, live in a metropolitan area, and be moderate risk or problem gamblers. AED consumers are more likely to report moderate levels of psychological distress. CONCLUSIONS: Our findings in relation to problem gambling and psychological distress are novel and require further targeted investigation. Health promotion strategies directed toward reducing ED and AED use should focus on young people living in metropolitan areas and potentially be disseminated through locations where gambling takes place.

Trends in alcohol-attributable morbidity and mortality for Victoria, Australia from 2000/01 to 2009/10.

BACKGROUND: To examine trends in alcohol-attributable morbidity (AAMorb) (2000/01-2009/10) and mortality (AAMort) (2000-07) by age, sex and region. METHODS: Time-series analyses of population data for Victoria, Australia. We used joinpoint regression to quantify trends by estimating quarterly percent change (QPC) for rates of morbidity and mortality. We present the average QPC (AQPC) as a weighted average of QPCs. A test of parallelism was used to examine pairwise differences. RESULTS: AAMorb increased significantly over time for Victoria (AQPC = 1.0%, 95% confidence interval 0.8-1.2). While females (1.6, 1.1-2.0), age groups 25-44 (1.0, 0.9-1.1) and 45-64 (1.2, 0.2-2.2), and metropolitan population (1.2, 0.5-1.9) were broad subgroups more at risk, multivariate analysis detected specific increases for metropolitan females aged 15-44 (1.8, 1.0-2.6) and 45+ (1.6, 0.2-3.0). Relatively greater increases in morbidity among metropolitan subgroups were widespread. AAMort remained stable for Victoria and for most subgroups, although significant declines in mortality were specifically experienced by metropolitan 15-24 (-2.0, -2.9 to -1.0) and 25-44 (-1.0, -1.7 to -0.3) age groups, and by regional males aged 45+ (-0.8, -1.3 to -0.3). Metropolitan males aged 45+ were a special high-risk population. DISCUSSION: Our study has identified overlooked subgroups as being at increasing risk for alcohol-attributable chronic harm necessitating their inclusion in future policies for harm reduction.

Factors influencing mortality among alcohol and drug treatment clients in Victoria, Australia: the role of demographic and substance use characteristics.

OBJECTIVE: Clinical studies consistently identify alcohol- and drug-related treatment populations as more likely to die prematurely compared with an age-matched general population. However, demographic characteristics and primary drug of concern as predictors of mortality risk following treatment have not been adequately explored. This paper examines relationships between substance use, demographic factors and mortality among alcohol and drug treatment clients. METHOD: A retrospective cohort incorporating 7 years of data was utilised to examine mortality outcomes in the 2 years following treatment among Victorian clients recorded on the Alcohol and Drug Information Service (ADIS) database by linking partial client identifiers with the National Death Index (NDI). A cohort of 18,686 clients engaged in at least one course of treatment over a 12-month period was included. Analysis was of crude and standardised mortality rates across client groups in terms of the presenting drug of concern for treatment and demographic characteristics. RESULTS: A higher risk of premature death was associated with older age, being male, not being employed, living alone, medical and psychiatric comorbidity, recent injecting, and a history of intensive drug treatment access. Alcohol treatment clients had the worst prognosis. After adjustment for client characteristics, alcohol treatment clients experienced a significantly higher rate of death compared with other clients. CONCLUSIONS: Findings from these previously unexplored data highlight the need to increase awareness of the range and magnitude of risks associated with harmful alcohol use, and to identify approaches to enhance treatment effectiveness to reduce negative outcomes following treatment for populations at elevated risk of harm.

Creating supportive clinical learning environments: an intervention study.

AIM: To assess the impact of an intervention aimed to build capacity of registered nurses to enhance the clinical learning environment for undergraduate nursing students. Workplace learning is vital for the development of skills, attributes and knowledge of student nurses. Registered nurses need to be appropriately prepared to maximise student learning during clinical placement. BACKGROUND: The quality of student learning during clinical practicum is largely dependent on interactions with ward staff. DESIGN: A quasi-experimental design. METHOD: Measurement of students' perceptions of the psycho social learning environment during and outside of the intervention period was used to evaluate the capacity building intervention. The capacity building intervention consisted of interactive education in clinical areas over a six-week period for registered nurses in two acute surgical wards. RESULTS: First, second and third year students (n = 62) who undertook their clinical practicum in the two surgical wards, before, during and six months after the capacity building intervention assessed the psycho-social learning environment at the time of their clinical practicum. Findings showed that students who undertook their clinical practicum during the intervention period rated the psycho-social clinical learning environment significantly higher than students who undertook their practicum at times outside of the intervention period. CONCLUSIONS: An experienced researcher/educator conducting capacity building sessions can effectively assist and support registered nurses to engage with students. RELEVANCE TO CLINICAL PRACTICE: Capacity building sessions can improve practice, however, structures and processes that ensure continuation of practice change need to be embedded for improvements to be sustained.

National Ambulance Surveillance System: A novel method using coded Australian ambulance clinical records to monitor self-harm and mental health-related morbidity.

Self-harm and mental health are inter-related issues that substantially contribute to the global burden of disease. However, measurement of these issues at the population level is problematic. Statistics on suicide can be captured in national cause of death data collected as part of the coroner's review process, however, there is a significant time-lag in the availability of such data, and by definition, these sources do not include non-fatal incidents. Although survey, emergency department, and hospitalisation data present alternative information sources to measure self-harm, such data do not include the richness of information available at the point of incident. This paper describes the mental health and self-harm modules within the National Ambulance Surveillance System (NASS), a unique Australian system for monitoring and mapping mental health and self-harm. Data are sourced from paramedic electronic patient care records provided by Australian state and territory-based ambulance services. A team of specialised research assistants use a purpose-built system to manually scrutinise and code these records. Specific details of each incident are coded, including mental health symptoms and relevant risk indicators, as well as the type, intent, and method of self-harm. NASS provides almost 90 output variables related to self-harm (i.e., type of behaviour, self-injurious intent, and method) and mental health (e.g., mental health symptoms) in the 24 hours preceding each attendance, as well as demographics, temporal and geospatial characteristics, clinical outcomes, co-occurring substance use, and self-reported medical and psychiatric history. NASS provides internationally unique data on self-harm and mental health, with direct implications for translational research, public policy, and clinical practice. This methodology could be replicated in other countries with universal ambulance service provision to inform health policy and service planning.

The National Ambulance Surveillance System: A novel method for monitoring acute alcohol, illicit and pharmaceutical drug related-harms using coded Australian ambulance clinical records.

Although harmful consumption of alcohol and other drugs (both illicit and pharmaceutical) significantly contribute to global burden of disease, not all harms are captured within existing morbidity data sources. Indeed, harms occurring in the community may be missed or under-reported. This paper describes the National Ambulance Surveillance System, a unique Australian system for monitoring and mapping acute harms related to alcohol and other drug consumption. Data are sourced from paramedic electronic patient care records provided by ambulance services from across Australia. Coding occurs in a purpose-built system, by a team of specialised research assistants. Alcohol, and specific illicit and pharmaceutical drugs, rather than broad drug classes, are manually coded and the dataset is reviewed and cleaned prior to analysis. The National Ambulance Surveillance System is an ongoing, dynamic surveillance system of alcohol and other drug-related harms across Australia. The data includes more than 140 output variables per attendance, including individual substances, demographics, temporal, geospatial, and clinical data (e.g., Glasgow Coma Scale score, naloxone provision and response, outcome of attendance). The National Ambulance Surveillance System is an internationally unique population-level surveillance system of acute harms arising from alcohol and other drug consumption. Dissemination of National Ambulance Surveillance System data has been used to inform and evaluate policy approaches and potential points of intervention, as well as guide workforce development needs and clinical practice at the local and national level. This methodology could be replicated in other countries.

Harms associated with extramedical use of prescription opioid analgesics in Australia: A scoping review.

BACKGROUND: Evidence is accumulating globally on harms from extramedical prescription opioid analgesic (POA) use. OBJECTIVE: The aim of this scoping review was to explore harms and documented risk factors associated with extramedical POA use in Australia. METHODS: MEDLINE, EMBASE, PsycINFO and CINAHL were searched for original studies published between January 2000 and February 2018. Studies were eligible for inclusion if: 1) POA use was explicitly reported, 2) extramedical use was evident 3) harm was explicitly reported, 4) data were collected in/after 2000, 5) conducted in adults and 6) undertaken in Australia. RESULTS: We identified 560 articles and 16 met the inclusion criteria. Harms reported from extramedical POA use included: increased health service utilization (n = 5), non-fatal overdose (n = 6), fatal overdose (n = 5), injection-related injuries or diseases (n = 4), engagement in crime (n = 2), loss of employment (n = 1), and foreign body pulmonary embolization (n = 1). Multiple drug toxicity was reported as the cause of death in up to 83% of fatal overdose cases. Risk factors for harm included being male, aged 31-49 years, a history of chronic non-cancer pain, mental health disorders and/or substance abuse, and concomitant use of benzodiazepines, antidepressants or other centrally-acting substances. CONCLUSION: Extramedical use of POAs is associated with a range of harms, including fatal and non-fatal overdose. Polysubstance use with other centrally-acting substances was often implicated. No published studies used linked data sources to provide a comprehensive overview of the extent of POA use or harm in Australia. Future research should focus on undertaking longitudinal cohort studies with linked data sources.

Pharmaceutical opioid overdose deaths and the presence of witnesses.

BACKGROUND: In the past two decades, rates of pharmaceutical opioid use and harms resulting from their use (including death) have risen. The present study identified a series of fatal opioid overdoses where there was evidence that witnesses had noted symptoms consistent with overdose, and examined associated contextual factors. METHODS: A retrospective review was undertaken utilising the Coroners Court of Victoria's Overdose Deaths Register for pharmaceutical opioid overdose deaths between 2011 and 2013. Information on the source of pharmaceutical opioids, co-contributing drugs, history of drug dependence, and mental illness was extracted and coded. RESULTS: Pharmaceutical opioids were involved in 587 deaths, and within these, 125 cases (21%) were witnessed. The majority of these witnessed deaths (77.6%) occurred at the deceased's residence, with the witness being a partner or unrelated acquaintance who did not realise the significance of what they were witnessing. The most common contributing pharmaceutical opioids were methadone (49.6%), codeine (32.0%), and oxycodone (19.2%), with the source more often prescribed than diverted. Co-contributing drugs were involved in 110 cases, with the most common being benzodiazepines. Evidence of current dependence and mental illness was found in 53.6% of cases. CONCLUSION: Most pharmaceutical opioid overdose deaths with a witness present occurred in the deceased's home, with symptoms of overdose being noted, but not acted upon. These findings support the trialling of education and/or naloxone to partners and family members of people who use pharmaceutical opioids in order to reduce overdose deaths.

Insomnia and Regulation of Sleep-Wake Cycle With Drugs Among Adolescent Risky Drinkers.

STUDY OBJECTIVES: We aimed to explore symptoms of insomnia in a group of youths characterized as engaging in risky drinking, their use of drugs as sleep/ wake aids, and the relationships between alcohol and other drug use and insomnia. METHODS: Face-to-face interviews were conducted with 596 Australian 14 to 19-year-olds identified as engaging in regular risky drinking. They completed the Insomnia Severity Index and were assessed for recent alcohol and other drug use, including drugs used specifically as sleep aids or to stay awake. Alcohol-related problems, emotional distress, self-control, and working outside of traditional hours were also assessed using validated scales. RESULTS: More than one-third of the study participants (36%) reported moderate to very severe sleep-onset insomnia, and 39% screened positive for clinical insomnia using adolescent criteria. Three-fourths used drugs in the past 2 weeks to regulate their sleep cycle (65% used stimulants to stay awake, mainly caffeine, and 32% used a depressant to get to sleep, mainly cannabis). Regression analyses showed that after controlling for variables such as sex, emotional distress, self-control, alcohol use problems, and past 6-month illicit or non-prescribed drug use, those who used drugs specifically to get to sleep or to stay awake were 2.0 (P < .001) and 1.7 (P = .02) times more likely to report clinical insomnia, respectively. CONCLUSIONS: Insomnia was commonly reported in this community sample of adolescents characterized as engaging in risky drinking. Those with symptoms of insomnia appeared to be managing their sleep-related symptoms through alcohol and other drug use, which may have further exacerbated their sleep issues.

Youth perceptions of alcohol advertising: are current advertising regulations working?

OBJECTIVES: We investigated young people's exposure to alcohol advertising, their intentions to consume and purchase alcohol products following the viewing of advertisements, and whether they perceived the actors in the advertisements as being under the age of 25 years. METHODS: Face-to-face interviews were completed with 351 risky drinking 16-19-year-old Australians, with a sub-sample (n=68) responding to a range of alcohol advertisements in an in-depth interview. RESULTS: Participants were exposed to alcohol advertisements from an average of seven specific contexts in the past 12 months, with younger adolescents more likely to recall TV and outdoor billboards (n=351). Positive perception of advertisements was associated with increased intention to use and to purchase advertised products (n=68). A liqueur advertisement actor was perceived by 94% as being under 25 years-old, and almost 30% thought the advertisement was marketed at people younger than 18 years of age. CONCLUSIONS: Young people's perceptions of alcohol advertising are not necessarily in line with expert/industry assessment; products are sometimes marketed in a way that is highly appealing to young people. Greater appeal was associated with increased intention to consume and to purchase products. Implications for public health: These results indicate deficiencies in the effectiveness of current advertising codes in regard to protecting the health and wellbeing of adolescents.

Alcohol-related serious road traffic injuries between 2000 and 2010: A new perspective to deal with administrative data in Australia.

BACKGROUND: According to the most recent statistics from the World Health Organization, 1.2 million people die or are injured on the world's roads every year. Drink-driving continues to be a major risk factor for road traffic crashes, with 22% of serious road injuries (SRIs) in Victoria involving a blood alcohol concentration (BAC) equal to or above the legal driving limit of 0.05g/mL. Use of police and hospital data to determine alcohol involvement in SRIs is not reliable, with researchers using proxy measures such as high alcohol hours (HAH). This paper examines patterns of alcohol-related SRIs based on reported BAC versus the surrogate HAH measure. METHODS: Trends over a 10year period (2000-2010) were examined, comparing four different SRI rates (low alcohol hours (LAH), LAH with positive BAC, HAH, HAH with positive BAC). Discontinuities in the data series were also examined. SRI data were drawn from the Road Networks Database of VicRoads containing information on all reported road crashes in Victoria. RESULTS: For the 10year period there were 52,286 reported SRIs relating to the driver. Of the incidents where a driver's reading was recorded, 44% had a recorded BAC exceeding Victoria's legal limit of 0.05% and a further 23% had a BAC below the legal limit. During the period over 17,000 (or 34%) SRIs occurred during HAH. Where a BAC had been recorded during HAH, almost 60% exceeded the legal limit and a further 20% had some positive recording of BAC. Where SRI drivers had a recorded BAC during LAH, 58% had a positive BAC (31% with a BAC over the legal limit). While it is likely that an SRI occurring during HAH will be associated with a positive BAC (80%), of which 60% will be above the legal limit, almost 60% of SRIs during LAH had a positive BAC, with 31% above the legal limit. CONCLUSION: There was no significant change in overall alcohol-related SRI rates between 2000 and 2010, suggesting that policies and procedures implemented to decrease drink-driving have not reduced alcohol-related SRI rates. In the absence of a reliable direct measure (i.e., BAC readings) this paper demonstrated the utility of the surrogate HAH measure for determining changes in alcohol-related serious road injuries. Further, the unmet need for routine BAC testing in SRIs occurring during LAH requires further exploration given the significant proportion of SRIs involving positive BAC during these times.
