Funding Amount

Summary
This study will quantify the impact of opioid substitution therapy (OST; methadone or buprenorphine) on two important outcomes for opioid dependent prisoners: mortality, particularly in the post-release period; and subsequent criminal activity. The study will have almost 600,000 person-years of follow-up over 22 years, allowing fine grained analyses of disadvantaged subpopulations. The study has clear implications for the health of this population, crime reductions, and cost savings.
Pharmaceutical Opioid Analgesic (POA) Dependence And Treatment Responses

Summary
Dependence on opioid based pain medication is a rapidly growing health concern in Australia. In the United States more people die each year from misusing pain medication than from using illicit drugs like heroin. Dr Suzanne Nielsen, an emerging expert in pharmaceutical misuse, will undertake essential research to understand the dependence to opioid pain medication in Australia and to develop appropriate treatment responses.

Summary
Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to ....Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to switch to alternative therapies. This provides an objective method of planning treatment that focuses on suppressing heroin use. The potential subjects of the study are the 50% of patients who continue to use heroin regularly during treatment. All will undergo assessment involving measurement of blood levels of methadone, testing of effects and side-effects of methadone, and monitoring of safety. Half will be randomly allocated to usual care, and half to therapeutic drug monitoring, with dose adjustments according to the results of testing. At 3 and 6 months all subjects will undergo repeat test sessions. It is hypothesized that those in the experimental group will be using less heroin (confirmed by hair testing). It is expected that the study will also identify a small group of subjects with genetically different opioid receptors, who will require very high doses of methadone to be stabilized. The study will allow a detailed analysis of how best to monitor dose adequacy; the relationship between withdrawal symptoms, methadone blood levels, and heroin use, and will provide the first clear investigation of the relationship between changes in methadone blood concentration and certain potentially dangerous changes in the electrical activity of the heart. The intended outcome of this research project is a model for a higher standard methadone program that is more effective in reducing the problems of heroin use in our community.Read moreRead less
