Although most unintentional opioid deaths in Australia are attributed to pharmaceutical opioids, take-home naloxone (THN) programmes have to date predominantly targeted people using illicit opioids in drug treatment and harm reduction settings. We sought to examine the feasibility of delivering THN brief interventions (THN-BIs) with intranasal naloxone in EDs.This pilot feasibility study was conducted across three major metropolitan EDs in Sydney and Melbourne. ED staff were surveyed about their perspectives regarding THN before completing a 30-min training programme in THN-BI delivery. Patients presenting with opioid overdose or considered high risk for future overdose were eligible to receive the THN-BI. Staff survey responses were compared between hospitals and provider types using one-way analysis of variances. Patient demographic and clinical characteristics were extracted from medical records and compared between hospitals and overdose type using Fisher's exact test and one-way analysis of variances.One hundred and twenty-two ED staff completed the survey. One hundred and ten (90.2%) agreed that EDs should provide THN-BIs, whereas 23 (19.2%) identified time constraints and 17 (12.9%) felt uncomfortable discussing overdose with patients. Fifty-seven patients received the THN-BI, with the majority (n = 50, 87.7%) having presented following opioid overdose. The median age was 44 years and 40 (71.4%) were men. Two-thirds of the overdoses (n = 31, 66.0%) were attributed to heroin with one-third (n = 16, 34%) being attributed to pharmaceutical opioids.ED-based delivery of THN-BIs can reach a wide range of individuals at-risk of overdose. The present study supports the feasibility of THN interventions in EDs and underscores the importance of addressing implementation barriers including staff training.

To assess the effectiveness of ultra-brief interventions (ultra-BI) or technology-involved preventive measures in the ED to reduce alcohol harm and risky drinking. Medline, Embase, PsycINFO, CINAHL and EBM reviews were searched for articles published between 1996 and 2015. Randomised controlled trials and quasi-randomised trials, which compared an ultra-BI with screening, standard care or minimal intervention for adults and adolescents at risk for alcohol-related harm presenting to an ED, were included. Outcomes of interest were frequency of alcohol consumption, quantity of alcohol consumed, binge drinking and ED representation. Thirteen studies (nine single centre and four multicentre) were included. Six studies showed a significant reduction in the quantity consumed with intermediate effect size at 3 months (d = -0.40) and small effect size at 12 months (d = -0.15). Two studies showed a significant reduction in binge drinking with small effect size at 3 months (d = -0.12) and 12 months (d = -0.09). No studies showed an effect on frequency of alcohol consumption or ED representation. Heterogeneity in study design, definition of risky, harmful or hazardous alcohol use, intervention types, outcomes, outcome timeframes and outcome measures prevented the performance of quantitative meta-analysis. Despite its limited effectiveness in reducing alcohol use in the short-term, with the large number of people attending EDs with risky drinking, the use of an effective ultra-BI would have the potential to have a measurable population effect.
