Key findings from the WHO collaborative study on substitution therapy for opioid dependence and HIV/AIDS.

AIMS: Opioid substitution treatment has been studied extensively in industrialized countries, but there are relatively few studies in developing/transitional countries. The aim of this study was to examine the effectiveness of opioid substitution treatment (OST) in less resourced countries. DESIGN: Longitudinal cohort study. SETTING: Purposively selected OST sites in Asia (China, Indonesia, Thailand), Eastern Europe (Lithuania, Poland, Ukraine), the Middle East (Iran) and Australia. PARTICIPANTS: Seven hundred and twenty-six OST entrants. MEASUREMENTS: Participants were interviewed at treatment entry, 3 and 6 months. Standardized instruments assessed drug use, treatment history, physical and psychological health, quality of life, criminal involvement, blood-borne virus (BBV) risk behaviours and prevalence of human immunodeficiency virus (HIV) and hepatitis C. FINDINGS: Participants were predominantly male, aged in their early 30s and had attained similar levels of education. Seroprevalence rates for HIV were highest in Thailand (52%), followed by Indonesia (28%) and Iran (26%), and lowest in Australia (2.6%). Treatment retention at 6 months was uniformly high, averaging approximately 70%. All countries demonstrated significant and marked reductions in reported heroin and other illicit opioid use; HIV (and other BBV) exposure risk behaviours associated with injection drug users (IDU) and criminal activity, and demonstrated substantial improvement in their physical and mental health and general wellbeing over the course of the study. CONCLUSIONS: OST can achieve similar outcomes consistently in a culturally diverse range of settings in low- and middle-income countries to those reported widely in high-income countries. It is associated with a substantial reduction in HIV exposure risk associated with IDU across nearly all the countries. Results support the expansion of opioid substitution treatment.

Determining a cut-off on the Severity of Dependence Scale (SDS) for alcohol dependence.

Optimal cut-off points on the Severity of Dependence Scale (SDS) indicative of clinically significant dependence have been determined for a range of substance types. This study aims to determine a cut-off point on SDS that discriminates between the presence and absence of a DSM-IV diagnosis of alcohol dependence. A structured interview was administered to 90 alcohol users in Sydney, Australia. Receiver Operating Characteristic curve analysis confirmed the utility of the SDS-alcohol for characterising and diagnosing persons with respect to their alcohol-dependent status to an accuracy of 85%. A SDS score of 3 or above was determined as optimal for characterising alcohol dependence. Evidence is also provided confirming that the SDS-alcohol is a valid, reliable uni-dimensional scale for measuring alcohol dependence. It has been demonstrated that the SDS-alcohol can be used to characterise an individual's alcohol-dependent status. A cut-off value for SDS-alcohol provides additional meaning and value to the scale for clients and clinicians and will enable researchers to characterise the prevalence of alcohol dependence in their target populations.

Regional differences in injecting practices and other substance use-related behaviour among entrants into opioid maintenance pharmacotherapy treatment in New South Wales, Australia.

BACKGROUND: Investigations of injecting drug users (IDUs) have been conducted largely in urban areas. Those studies that compare rural and urban IDUs often utilise small and possibly unrepresentative samples. AIM: To investigate regional differences in the characteristics of IDUs. METHODS: The study compared the demographic, drug use-related, and treatment characteristics of 1045 urban, 213 regional, and 254 rural opioid maintenance pharmacotherapy (OMP) treatment entrants recruited as part of a feasibility study into the implementation of a state-based treatment outcome monitoring system. RESULTS: Participants from regional and rural New South Wales (NSW) were significantly more likely to report sharing of needles and other injection equipment and higher non-opioid drug use and polydrug use than their urban counterparts. In addition, they were more likely to be living with dependent children, to be unemployed, and to be experiencing greater psychological problems than their urban counterparts. Needle sharing also was independently associated with being younger, female, having been arrested, or having non-opioid drugs of concern. CONCLUSIONS: Reasons for the higher rates of blood-borne virus (BBV) transmission risk-related behaviour among rural and regional IDUs should be investigated further and considered when planning for the targeted provision of harm reduction activities.

Development and validation of a brief instrument for routine outcome monitoring in opioid maintenance pharmacotherapy services: the brief treatment outcome measure (BTOM).

AIM: To develop a brief, multi-dimensional instrument for routine, on-going treatment outcome monitoring in alcohol and other drug (AOD) services in Australia and examine the underlying psychometric properties. This study focuses on opioid maintenance pharmacotherapy (OMP) services. DESIGN: Researcher-administered test-retest interviews and clinician administered interviews. SETTING: The test-retest interviews took place in two private and two public OMP clinics in Sydney, Australia. The clinician-administered interviews took place in 37 metropolitan, rural and prison OMP services in New South Wales, Australia. PARTICIPANTS: One hundred and sixty current OMP clients for the test-retest interviews and 2004 clients commencing OMP treatment for the clinician-administered interviews. MEASURES: Thirty-two items across the domains of dependence, blood-borne virus exposure risk, drug use, health/psychological functioning and social functioning. FINDINGS: The internal reliability of the brief treatment outcome measure (BTOM) is satisfactory. Retest reliabilities for the scales and drug use scores are good to excellent indicating their consistency with multiple measurements across time and different interviewers and concurrent validation of BTOM scales with analogous scales from similar instruments yielded acceptable agreement. Average completion times of the BTOM were 14.5 min, when administered in a research context and 21 min in a clinical context. CONCLUSIONS: A brief, valid and reliable questionnaire has been developed for monitoring treatment outcome over the range of OMP services. The BTOM contains a core set of outcome measures, which can be easily adapted for integration into routine clinical practice across the range of AOD services.

The Alcohol Treatment Outcome Measure (ATOM): a new clinical tool for standardising outcome measurement for alcohol treatment.

Whilst many instruments have been developed for screening and treatment outcome evaluation studies in the alcohol and other drug treatment (AOD) sector, very few are suitable for routine, ongoing use by clinicians. The aim of the current study was to assess the psychometric properties of the Alcohol Treatment Outcome Measure (ATOM). The ATOM was designed to measure the key outcomes of alcohol treatment whilst remaining a brief and easy to use clinical tool. Participants (N=134) with a concern for their alcohol use were recruited from AOD treatment agencies and interviewed on two occasions one week apart. Results indicate that the ATOM has overall good to excellent test-retest and inter-rater reliability; and satisfactory concurrent validity and internal reliability. The instrument also demonstrated the ability to measure change in client functioning over time. Results suggest that the ATOM can be used successfully and confidently within alcohol treatment services.

Dispensing opioid substitution treatment: practices, attitudes and intentions of community-based pharmacists.

INTRODUCTION AND AIMS: Community-based pharmacists (CPs) play a pivotal role in the provision of opioid substitution treatment (OST). This study examined practices, experiences, attitudes and intentions of a sample of South Australian pharmacists involved with the provision of OST. DESIGN AND METHODS: A random sample, stratified by geographic location, of 50 SA CPs were administered a telephone survey. The survey included pharmacist and pharmacy details, current practices, problems experienced, attitudes towards and future intentions in relation to the provision of OST. RESULTS: Pharmacists indicated high levels of support for the OST programme and most (98%) intended to continue providing OST. Sixty-four per cent of all pharmacists, and significantly more rural pharmacists (90%), indicated that they were willing to take on additional clients. Metropolitan pharmacists dosed greater numbers of OST clients (median = 7) than rural pharmacists (median = 4). There was a strong positive correlation between number of regular clients seen and problems experienced by pharmacists. Seventy per cent of pharmacists reported detecting no diversion of pharmacotherapy medication. DISCUSSION AND CONCLUSIONS: Despite reports to the contrary, pharmacists appear to be generally positively predisposed to providing OST. Policies aimed at retaining pharmacists, particularly in resource poor rural areas, could consider embracing a shared-care approach between general practitioners and pharmacists.
