Monograph No. 10: DATA SOURCES ON ILLICIT DRUG USE AND HARM IN AUSTRALIA

This Monograph (No. 10) provides a description and review of the routinely-collected data sources available in Australia that capture information on illicit drug use and related harms. Based on work undertaken at the National Drug and Alcohol Research Centre and Turning Point Alcohol and Drug Centre, it is intended as a reference document to provide interested persons with a guide to the type and nature of the information available in Australia. It reviews available data across four main domains; patterns and prevalence of use, health consequences, market characteristics and drug crime. For a review of information available on the economic aspects of illicit drug use and harm see Monograph 09 of this series

Afghanistan has a sizeable problem with opioid use

In 2010, opioid use and dependence made the largest contribution to morbidity and mortality from illicit drug use, contributing to premature death from drug overdose and suicide, and in those who inject these drugs, infection with HIV and other blood-borne viruses. Dependence also produced considerable disability.1 Afghanistan has a tradition of opium smoking, and has long been a major source of illegal opiates for eastern and western Europe. In the past decade, Afghans have also reportedly begun to inject heroin and use pharmaceutical opioids

Drug use and risk behaviours among injecting drug users: a comparison between sex workers and non-sex workers in Sydney, Australia

BACKGROUND: This paper examines the differences in demographics, drug use patterns and self reported risk behaviours between regular injecting drug users (IDU) who report engaging in sex work for money or drugs and regular injecting drug users who do not. METHODS: Cross sectional data collected from regular IDU interviewed as part of the New South Wales (NSW) Illicit Drug Reporting System (IDRS) in 2003 were analysed. RESULTS: IDU who reported engaging in sex work were more likely to be female, and identify as being of Aboriginal and/or Torres Strait Islander descent. They initiated injecting drug use at a significantly younger age and were more likely to report injection related problems than IDU who had not engaged in sex work. There were no differences in the drug classes used, but findings suggested that the sex workers tended to be more frequent users of crystalline methamphetamine (ice) and benzodiazepines. CONCLUSION: The similarities between these groups were more striking than the differences. Further research, examining a larger sample is needed to clarify whether injecting drug users who are sex workers have heavier use patterns

The effect of person, treatment and prescriber characteristics on retention in opioid agonist treatment:a 15-year retrospective cohort study

AbstractBackground and Aims: There is limited evidence on the relationship between retention in opioid agonist treatment for opioid dependence and characteristics of treatment prescribers. This study estimated retention in buprenorphine and methadone treatment and its relationship with person, treatment, and prescriber characteristics. Design: Retrospective longitudinal study.Setting: New South Wales, Australia.Participants: People entering the opioid agonist treatment program for the first time between August 2001 and December 2015.Measurements: Time in opioid agonist treatment (primary outcome) was modelled using a generalised estimating equation model to estimate associations with person, treatment, and prescriber characteristics. Findings: The impact of medication type on opioid agonist treatment retention reduced over time; risk of leaving treatment when on buprenorphine compared with methadone was higher among those that entered treatment earlier (e.g. 2001-2003: OR 1.59, 95% CI 1.44-1.74) and lowest among those that entered most recently (2013-2015: OR 1.24, 95% CI 1.12-1.37). In adjusted analyses, risk of leaving was reduced among people whose prescriber had longer tenure of prescribing (e.g. 3 versus 8 years: OR 0.94, 95% CI 0.93-0.95) compared with prescribers with shorter tenure. Aboriginal and Torres Strait Islander people, being of younger age, past-year psychosis disorder, and having been convicted of more criminal charges in the year prior to treatment entry were associated with increased risk of leaving treatment. Conclusion: In New South Wales, Australia, retention in buprenorphine treatment for opioid dependence, compared with methadone, has improved over time since its introduction in 2001. Opioid agonist treatment (OAT) retention is affected not only by characteristics of the person and his or her treatment, but also of the prescriber, with those of longer prescribing tenure associated with increased retention of people in OAT. <br/

Trends and characteristics of accidental and intentional codeine overdose deaths in Australia

Examines trends in codeine-related mortality rates in Australia, and the clinical and toxicological characteristics of codeine-related deaths. Abstract Objectives: To examine trends in codeine-related mortality rates in Australia, and the clinical and toxicological characteristics of codeine-related deaths. Design and setting: Analysis of prospectively collected data from the National Coronial Information System on deaths where codeine toxicity was determined to be an underlying or contributory cause of death. The study period was 2000–2013. Main outcome measures: Population-adjusted numbers (per million persons) of (1) codeine-related deaths, classified by intent (accidental or intentional); and (2) heroin- and Schedule 8 opioid-related deaths (as a comparator). Results: The overall rate of codeine-related deaths increased from 3.5 per million in 2000 to 8.7 per million in 2009. Deaths attributed to accidental overdoses were more common (48.8%) than intentional deaths (34.7%), and their proportion increased during the study period. High rates of prior comorbid mental health (53.6%), substance use (36.1%) and chronic pain (35.8%) problems were recorded for these deaths. For every two Schedule 8 opioid-related deaths in 2009, there was one codeine-related death. Most codeine-related deaths (83.7%) were the result of multiple drug toxicity. Conclusions: Codeine-related deaths (with and without other drug toxicity) are increasing as the consumption of codeine-based products increases. Educational messages are needed to better inform the public about the potential harms of chronic codeine use, especially in the context of polypharmacy

Trends in drug-related hospitalisations in Australia, 2002-2022
