GP attitudes to managing drug- and alcohol-dependent patients: a reluctant role

Challenges of methadone maintenance treatment decentralisation from Vietnamese primary care providers' perspectives

INTRODUCTION

Decentralising methadone maintenance treatment to primary care improves patients' access to care and their drug and HIV treatment outcomes. However, primary care providers (PCP), especially those working in limited-resource settings, are facing great challenges to provide quality methadone treatment. This study explores the challenges perceived by PCP providing methadone treatment at commune health centres in a mountainous region in Vietnam.

METHOD

We conducted in-depth interviews with 26 PCP who worked as program managers, physicians, counsellors, pharmacists and medication dispensing staff at the methadone programs of eight commune health centres in Dien Bien, Vietnam, in November and December 2019. We used the health-care system framework in developing the interview guides and in summarising data themes.

RESULTS

Participants identified major challenges in providing methadone treatment in commune health centres at the individual, clinic and environmental levels. Individual-level challenges included a lack of confidence and motivation in providing methadone treatment. Clinic-level factors included inadequate human resources, lack of institutional support, insufficient technical support, lack of referral resources and additional support for patients. Environment-level factors comprised a lack of reasonable policies on financial support for providers at commune health centres for providing methadone treatment, lack of regulations and mechanisms to ensure providers' safety in case of potential violence by patients and to share responsibility for overdose during treatment.

DISCUSSION AND CONCLUSION

PCP in Vietnam faced multi-level challenges in providing quality methadone treatment. Supportive policies and additional resources are needed to ensure the effectiveness of the decentralisation program.

Qualitative exploration of barriers to alcohol management in patients with chronic disease in a regional setting

Chronic diseases are a major contributor to the burden of disease in Australia. Alcohol consumption is similar in people with chronic disease and the general public, and may contribute to management challenges. In regional Australia, there are limited options for the management of excess alcohol consumption, so most of this burden falls to general practitioners. This study explored how staff in general practices are managing alcohol in patients with chronic disease with a view to determining what additional services may be appropriate. Brief interviews were conducted with doctors, nurses and allied health practitioners across three general practices in a regional centre. Interviews were analysed using abductive thematic techniques to elicit broad themes. In all, 18 interviews were conducted. All interviewees found the management of patients with chronic disease who were drinking in excess of guidelines to be challenging. The complexity of patients, in terms of health needs and social circumstances, affected management and self-care. Australian drinking cultural norms also affected patients' and practitioners' behaviour. Multidisciplinary care was highlighted by all health professionals; however, there were challenges maintaining staff motivation, a lack of training in alcohol management and a lack of referral or assistance services. Experienced practitioners identified that the patient was the key stakeholder who needed to take ownership of their health. The combined burden of excess alcohol consumption and chronic disease is a common management challenge faced by staff in general practice. Although there was evidence of awareness of the issue and a concerted effort to address the problem, most staff felt they had inadequate training, skills and resources. More undergraduate or postgraduate training in alcohol management and more resources are required to support general practitioners in this area.

How do people who use drugs experience treatment? A qualitative analysis of views about opioid substitution treatment in primary care (iCARE study)

OBJECTIVE

To understand the most significant aspects of care experienced by people in opioid substitution treatment (OST) in primary care settings.

DESIGN

Semistructured individual interviews were conducted, following the critical incidents technique. Interview transcripts were analysed following a thematic analysis approach.

PARTICIPANTS

Adults aged 18 years or older, receiving OST in UK-based primary care services.

RESULTS

Twenty-four people in OST were interviewed between January and March 2019. Participants reported several aspects which were significant for their treatment, when engaging with the primary care service. These were grouped into 10 major themes: (1) humanised care; (2) individual bond/connection with the professional; (3) professionals' experience and knowledge; (4) having holistic care; (5) familiarity; (6) professionals' commitment and availability to help; (7) anonymity; (8) location; (9) collaborative teamwork; and (10) flexibility and changes around the treatment plan.

CONCLUSIONS

This study included first-hand accounts of people who use drugs about what supports them in their recovery journey. The key lessons learnt from our findings indicate that people who use drugs value receiving treatment in humanised and destigmatised environments. We also learnt that a good relationship with primary care professionals supports their recovery journey, and that treatment plans should be flexible, tailor-made and collaboratively designed with patients.

Factors influencing the implementation of screening and brief interventions for alcohol use in primary care practices: a systematic review using the COM-B system and Theoretical Domains Framework

BACKGROUND

Alcohol is a leading risk factor contributing to the global burden of disease. Several national and international agencies recommend that screening and brief interventions (SBI) should be routinely delivered in primary care settings to reducing patients' alcohol consumption. However, evidence shows that such activities are seldom implemented in practice. A review of the barriers and facilitators mediating implementation, and how they fit with theoretical understandings of behaviour change, to inform the design of implementation interventions is lacking. This study aimed to conduct a theory-informed review of the factors influencing general practitioners' and primary care nurses' routine delivery of alcohol SBI in adults.

METHODS

A systematic literature search was carried out in four electronic databases (Medline, CINAHL, CENTRAL, PsycINFO) using comprehensive search strategies. Both qualitative and quantitative studies were included. Two authors independently abstracted and thematically grouped the data extracted. The barriers and facilitators identified were mapped to the domains of the Capability-Opportunity-Motivation-Behaviour system/Theoretical Domains Framework (TDF).

RESULTS

Eighty-four out of the 258 studies identified met the selection criteria. The majority of the studies reported data on the views of general practitioners (n = 60) and used a quantitative design (n = 49). A total of 660 data items pertaining to barriers and 253 data items pertaining to facilitators were extracted and thematically grouped into 46 themes. The themes mapped to at least one of the 14 domains of the TDF. The three TDF domains with the highest number of data units coded were 'Environmental Context and Resources' (n = 158, e.g. lack of time), 'Beliefs about Capabilities' (n = 134, e.g. beliefs about the ability to deliver screening and brief advice and in helping patients to cut down) and 'Skills' (n = 99, e.g. lack of training).

CONCLUSIONS

This study identified a range of potential barriers and facilitators to the implementation of alcohol SBI delivery in primary care and adds to the scarce body of literature that identifies the barriers and facilitators from a theoretical perspective. Given that alcohol SBI is seldom implemented, this review provides researchers with a tool for designing novel theory-oriented interventions to support the implementation of such activity.

The Experience of Violence Against Women Who Use Injection Drugs: An Exploratory Qualitative Study

BACKGROUND

While literature exists about persons who use injection drugs, few studies explore the experience of women who use these substances. Furthermore, even less research specifically focuses on the lives and experiences of homeless women who use injection drugs. What literature does exist, moreover, is often dated and primarily addresses concerns about infectious disease transmission among these women; and some highlight that these women have lives fraught with violence.

PURPOSE

To update this knowledge and better understand the lives of women who use injection drugs in the Canadian context.

METHODS

We undertook an exploratory qualitative study and we engaged in semi-structured interviews with 31 homeless women who use injection drugs in downtown Ottawa, Canada. We analyzed the data using the principles of applied thematic analysis.

RESULTS

Our data identified that violence pervaded the lives of our participants and that these experiences of violence could be categorized into three main areas: early and lifelong experiences of violence; violence with authority figures (e.g., police, healthcare); and societal violence toward women who use injection drugs.

CONCLUSIONS

We take these findings to mean that, violence toward women is rampant in Canada (not just internationally) and that healthcare workers play a role in propagating and addressing this violence.

The effect of alcohol consumption on clinical outcomes in regional patients with chronic disease: a retrospective chart audit

OBJECTIVE

To better understand the impact of alcohol consumption on the clinical management of chronic diseases in a regional general practice setting.

METHODS

A retrospective chart audit was undertaken of individual patient records at two large group general practices in Townsville, a regional Australian city. Three common indicator chronic diseases were selected that have clear management guidelines for general practice: type 2 diabetes; chronic obstructive pulmonary disease; and chronic kidney disease. The audits were analysed using SPSS software to examine the association between alcohol consumption on acquisition of clinical management targets and primary disease intermediate outcomes (haemoglobin A1c fraction; per cent of normal forced expiratory volume at one second; and estimated glomerular filtration rate).

RESULTS

A total of 457 records were audited. Higher-risk alcohol consumption is associated with reduced ability of patients to reach management targets (F[3,453]=3.68; p=0.012) and decreased standardised primary disease outcome (F[3,403]=2.86; p=0.037).

CONCLUSION

Higher-risk alcohol consumption is associated with reduced attainment of chronic disease management targets and worse chronic disease outcomes. Implications for public health: Alcohol consumption should be assessed frequently in people with chronic disease, especially when there is difficulty acquiring management targets or worsening of disease outcomes without a clear explanation. Better education about the potential associations between alcohol use and chronic disease would benefit those managing these complex conditions, both clinicians and patients.

Self-Rated Physical Health and Unmet Healthcare Needs among Swedish Patients in Opioid Substitution Treatment

Background

Individuals with opioid dependence are at increased risk of deteriorating health due to the lifestyle connected to heroin use. Barriers surrounding the healthcare system seem to hinder patients to seek help through conventional healthcare, even after entering opioid substitution treatment (OST), resulting in a high level of unmet healthcare needs. However, this field is still unexplored, with only a few studies focusing on general health within this population. The first step, in order to provide suitable and accessible primary healthcare, is to assess the extent of physical symptoms and unmet healthcare needs within the OST population, which, to this point, has been sparsely studied.

Aim

To assess OST patients' self-rated physical health and healthcare seeking behaviour.

Methods

Two-hundred and eighteen patients from four different OST sites answered a questionnaire regarding physical health and healthcare seeking.

Results

Patients in OST have a high degree of physical symptoms and a high degree of unmet healthcare needs. Sixty-six percent reported suffering from musculoskeletal pain. Fifty-six percent reported gastrointestinal symptoms. Genital problems and airway symptoms were reported by 47%, respectively, and dental problems were reported by 69% of the respondents. General unmet healthcare needs were reported by 82%. Musculoskeletal pain was positively correlated with having an unstable housing situation (AOR 4.26 [95% CI 1.73-10.48]), negatively correlated with male sex (AOR 0.45 [95% CI 0.22-0.91]), and positively correlated with age (AOR 1.04 [95% CI 1.01-1.07]). No statistically significant correlates of respiratory, gastrointestinal, genital, or dental symptoms were found.

Conclusion

Patients in OST carry a heavy burden of physical symptoms and unmet healthcare needs, potentially due to societal barriers. Patients' frequent visits to the OST clinics offer a unique opportunity to build a base for easily accessible on-site primary healthcare.

Optimising treatment in opioid dependency in primary care: results from a national key stakeholder and expert focus group in Ireland

BACKGROUND

Treatment for opioid dependence in Ireland is provided predominantly by general practitioners (GP) who have undergone additional training in opioid agonist treatment (OAT) and substance misuse. The National Methadone Treatment Programme (MTP) was introduced in 1998, and was designed to treat the opioid dependent population and to regulate the prescribing regimes at the time. The past two decades have seen the increased prescribing of methadone in primary care and changes in type of opioid abused, in particular, the increased use of over the counter (OTC) and prescription medications. Despite the scaling up of OAT in Ireland, drug related deaths however have increased and waiting lists for treatment exist in some areas outside the capital, Dublin. Two previous MTP reviews have made recommendations aimed at improving and scaling up of OAT in Ireland. This study updates these recommendations and is the first time that a group of national experts have engaged in structured research to identify barriers to OAT delivery in Ireland. The aim was to explore the views of national statutory and non-statutory stakeholders and experts on current barriers within the MTP and broader OAT delivery structures in order to inform their future design and implementation.

METHODS

A single focus group with a chosen group of national key stakeholders and experts with a broad range of expertise (clinical, addiction and social inclusion management, harm reduction, homelessness, specialist GPs, academics) (n = 11) was conducted. The group included national representation from the areas of drug treatment delivery, service design, policy and practice in Ireland.

RESULTS

Four themes emerged from the narrative analysis, and centred on OAT Choices and Patient Characteristics; Systemic Barriers to Optimal OAT Service Provision; GP Training and Registration in the MTP, and Solutions and Models of Good Practice: Using What You Have.

CONCLUSION

The study identified a series of improvement strategies which could reduce barriers to access and the stigma associated with OAT, optimise therapeutic choices, enhance interagency care planning within the MTP, utilise the strengths of community pharmacy and nurse prescribers, and recruit and support methadone prescribing GPs in Ireland.

Evaluation of a Shared-Care Program for Methadone Treatment of Drug Abuse: An International Perspective

The North Wales (United Kingdom) Shared-Care Program for methadone treatment of drug abuse was evaluated. The program involves shared care, inasmuch as general practitioners, pharmacists, and community drug workers are jointly involved in the methadone treatment of persons with drug abuse. Evaluation aimed to determine the program's (a) extent of use, (b) impact on patients, (c) positive and negative consequences for methadone reduction or discontinuation, and (d) advantages and disadvantages. Results suggested that the program is successful but identified targets for future improvement.

The science and practice of medication-assisted treatments for opioid dependence

This paper briefly reviews the evolution of opioid addiction treatment from humanitarian to scientific and evidence-based, the evidence bases supporting major medication-assisted treatments and adjunctive psychosocial techniques, as well as challenges faced by clinicians and treatment providers seeking to provide those treatments. Attitudes, politics, policy, and financial issues are discussed.

The accessibility, acceptability, health impact and cost implications of primary healthcare outlets that target injecting drug users: a narrative synthesis of literature

BACKGROUND

Injecting drug users (IDUs) are at increased risk of health problems ranging from injecting-related injuries to blood borne viral infections. Access to primary healthcare (PHC) is often limited for this marginalised group. Many seek care at emergency departments and some require hospital admission due to late presentation. The costs to both the individual and the health system are such that policymakers in some settings have implemented IDU-targeted PHC centres, with a number of models employed. However, there is insufficient evidence on the effectiveness of these centres to inform health service planning. A systematic review examining such interventions is not possible due to the heterogeneous nature of study designs. Nevertheless, an integrative literature review of IDU-targeted PHC may provide useful insights into the range of operational models and strategies to enhance the accessibility and acceptability of these services to the target population.

METHODS

Available literature describing the impact of IDU-targeted PHC on health outcomes, cost implications and operational challenges is reviewed. A narrative synthesis was undertaken of material sourced from relevant journal publications, grey literature and policy documents.

RESULTS

Several models have proven accessible and acceptable forms of PHC to IDUs, improving the overall healthcare utilisation and health status of this population with consequent savings to the health system due to a reduction in visits to emergency departments and tertiary hospitals.

CONCLUSIONS

Although such findings are promising, there remains a dearth of rigorous evaluations of these targeted PHC, with the public health impact of such outlets yet to be systematically documented.

Development of a nurse-led primary healthcare service for injecting drug users in inner-city Sydney

Injecting drug users (IDUs) experience numerous health problems, but report barriers to utilising general practitioners (GPs). A nurse-led Harm Minimisation-based Primary Healthcare (HMPH) service for IDUs was established within a needle and syringe program in inner-city Sydney with Area Health Service medical support and clinical governance. This paper aimed to describe the HMPH service, review service utilisation and assess nurses’ perceptions of their work with IDUs. A review of the most recent 200 clinic files was undertaken. Service utilisation, GP and other health service use and access were extracted and analysed using SPSS. A semi-structured qualitative interview with clinic nurses regarding their experience working with IDUs and local GPs was conducted and analysed. Since its inception in mid-2006, the service has been utilised by 417 clients. Of the most recent 200 files, blood-borne virus and sexually transmitted infection screening were the primary reason for presentation (64.5%). At least one follow-up visit was attended by 90% of clients. A total of 62% of clients reported consulting a GP in the last 12 months. The service provided 102 referrals. Nurses believed that IDUs tend to utilise GPs ineffectively and that self-care is a low priority, but that they can support IDUs to overcome some barriers to GPs and facilitate access. Targeted primary health care services led by nurses with focussed medical support and co-located with needle and syringe programs can fill an important gap in delivering and facilitating health care to IDUs.

Attitudes of undergraduate health science students towards patients with intellectual disability, substance abuse, and acute mental illness: a cross-sectional study

BACKGROUND

There is a long history of certain medical conditions being associated with stigma, stereotypes, and negative attitudes. Research has shown that such attitudes can have a detrimental effect on patients presenting with stigmatised medical conditions and can even flow on to impact their family. The objective of this study was to measure the attitudes of undergraduate students enrolled in six different health-related courses at Monash University toward patients with intellectual disability, substance abuse, and acute mental illness.

METHODS

A convenience sample of undergraduate students enrolled in six health-related courses in first, second and third years at Monash University were surveyed. The Medical Condition Regard Scale--a valid and reliable, self-report measure of attitudes--was administered to students along with a brief demographic form. Mean scores, t-tests, and ANOVA were used to analyse student attitudes. Ethics approval was granted.

RESULTS

548 students participated. Statistically significant differences were found between the courses (p = 0.05), year of the course (p = 0.09), and gender (p = 0.04) for the medical condition of intellectual disability. There was no statistically significant difference between the courses, year of the course, gender, and age group for substance abuse or acute mental illness conditions.

CONCLUSION

The findings suggest that students in undergraduate health-related courses, as a group, have a strong regard for patients with intellectual disability and some regard for patients with acute mental illness, but not for patients presenting with substance abuse problems.

Mailed treatment to augment primary care for alcohol disorders: a randomised controlled trial

INTRODUCTION AND AIMS

Remote delivery of interventions is needed to address large numbers of people with alcohol use disorders who are spread over large areas. Previous correspondence trials typically examined its effects as stand-alone treatment. This study aimed to test whether adding postal treatment to general practitioner (GP) support would lower alcohol use more than GP intervention alone.

DESIGN AND METHODS

A single-blind, randomised controlled trial with a crossover design was conducted over 12 months on 204 people with alcohol use disorders. Participants in an immediate correspondence condition received treatment over the first 3 months; those receiving delayed treatment received it in months 3-6.

RESULTS

Few participants were referred from GPs, and little intervention was offered by them. At 3 months, 78% of participants remained in the study. Those in immediate treatment showed greater reductions in alcohol per week, drinking days, anxiety, depression and distress than those in the delayed condition. However, post-treatment and follow-up outcomes still showed elevated alcohol use, depression, anxiety and distress. Greater baseline anxiety predicted better alcohol outcomes, although more mental distress at baseline predicted dropout.

DISCUSSION AND CONCLUSIONS

The study gave consistent results with those from previous research on correspondence treatments, and showed that high levels of participant engagement over 3 months can be obtained. Substantial reductions in alcohol use are seen, with indications that they are well maintained. However, many participants continue to show high-risk alcohol use and psychological distress.

Process evaluation of an out-patient detoxification service

This paper describes the process evaluation of an out-patient detoxification service (ODS) established by Drug Health Services (DHS) to increase the supervised withdrawal options for substance users in a Sydney metropolitan Area Health Service. The ODS aimed to provide a safe and effective supervised withdrawal to substance users who were at low risk of severe withdrawal, engage those with severe dependence in further treatment and increase the involvement of general practitioners (GPs) in the medical care of ODS clients. During its first 10 months of operation, the ODS received 199 inquiries, assessed 82 individuals and admitted 76 clients for detoxification. Withdrawal treatment proceeded without complications and within the expected time frames. Fifty-four clients completed withdrawal, 10 ceased treatment, 10 remained in treatment without completing withdrawal and two were transferred elsewhere. Clients who injected substances (mainly heroin) daily at admission, compared to others, were less likely to complete withdrawal and more likely to use a range of non-prescribed substances during withdrawal. One-fifth of clients went on to further treatment with DHS, attending at least once. Overall, the ODS met its goals, providing a safe and effective supervised withdrawal to local residents, especially women, young people and those withdrawing from benzodiazepines who had significant substance dependence, impairment and previous alcohol and other drug (AOD) treatment. Non-injecting substance users benefited most from the ODS in terms of withdrawal completion and ongoing treatment. The level of GP involvement in the conjoint care of ODS clients remained constant over time. The development and expansion of the ODS are discussed.

Patient and physician characteristics in relation to clinical decision making in methadone maintenance treatment

Delivery of methadone maintenance treatment (MMT) varies considerably between service providers, but the reasons for this are unclear. This two-phase study involved a controlled investigation of factors that influence clinical decision making by methadone-prescribing physicians in regard to three decision-making scenarios: (1) individuals seeking induction into MMT and existing patients seeking (2) replacement and (2) takeaway methadone doses. In phase 1, physicians (n = 17) rated the diagnostic merit of 87 patient factors for each scenario. Ratings suggested that decisions are influenced by a range of subjective and "nonmedical" patient factors (e.g., contact with drug subculture, appearance, employment status, social support, having children), in addition to more conventional information sources regarding patients' medical and treatment status (e.g., being pregnant, urinalysis evidence of opioid and poly drug use, signs of opioid withdrawal). Phase 2 (n = 296) investigated relationships between physician characteristics and responses to randomized-controlled case vignettes (decisions and confidence ratings) in which the amount and type of diagnostic and nondiagnostic patient information was controlled. Vignette responses were significantly related to physician characteristics (e.g., professional orientation, location, and experience) independent of the patient information provided. Delivery of MMT may vary due to the diversity of patient factors that influence decisions and variability between physicians in the way such information is used to form judgments. Training programs for methadone prescribers should account for these sources of potential variability in treatment management.

Hepatitis C-related discrimination among heroin users in Sydney: drug user or hepatitis C discrimination?

The hepatitis C virus (HCV) is a common infection among injecting drug users. There are currently few available data on the extent (or prevalence) of HCV-related discrimination. This study examined perceived discrimination among a sample of heroin users and sought to determine whether the discrimination was attributed to their drug user or HCV status. Heroin users were recruited through needle and syringe programmes and methadone clinics in Sydney and were asked about discrimination in the preceding 12 months. Four hundred and one heroin users were recruited, of whom 59% reported being HCV-positive. Discrimination was reported by 22% of the 237 IDUs who reported being HCV-positive, with 17% reporting that the discrimination occurred in the preceding 12 months. Sixty-seven incidents were reported, of which half were perceived to be due to their drug user status, 15% of these incidents were due to HCV status and 25% due to a combination of both. Twenty-five incidents occurred in a health-care setting, of which 13 resulted in the service being withheld. HCV is a serious public health concern, and if IDU are to be encouraged into drug treatment it is essential that service providers are perceived to be non-discriminatory. In managing IDU patients, health care workers need to be cognizant of the impact that their attitude has on treatment outcome.

Brief interventions: good in theory but weak in practice

A substantial body of research evidence has accumulated in support of the efficacy of brief interventions for a number of alcohol and drug-related problem areas, most notably alcohol and tobacco. This evidence has been used to exhort a range of professional groups such as general practitioners (GPs), and more recently emergency department hospital staff to engage in brief interventions. Internationally, however, these secondary prevention efforts have largely failed. Why have these proven interventions not been embraced by frontline workers? This is a little-asked question as efforts to press-gang unwilling professionals to take up the cudgel continue. This paper examines the characteristics of brief interventions and their principal delivery agents and explores reasons for the failure to move from efficacy to effectiveness. Given the prevention potential that rests with brief intervention, these are crucial questions to address. A key feature of brief intervention delivery also examined is the role of GPs versus the less well-explored option of the practice nurse. It will be proposed that perhaps we have the right vehicle but the wrong driver and that until closer scrutiny is made of this issue efforts in this key prevention area will continue to fail to achieve optimum results.

A comparison of buprenorphine treatment in clinic and primary care settings: a randomised trial

OBJECTIVE

To compare outcomes, costs and incremental cost-effectiveness of heroin detoxification performed in a specialist clinic and in general practice.

DESIGN AND SETTING

Randomised controlled trial set in a specialist outpatient drug treatment centre and six office-based general practices in inner city Sydney, Australia.

PARTICIPANTS

115 people seeking treatment for heroin dependence, of whom 97 (84%) were reinterviewed at Day 8, and 78 (68%) at Day 91.

INTERVENTIONS

Participants were randomly allocated to primary care or a specialist clinic, and received buprenorphine for 5 days for detoxification, then were offered either maintenance therapy with methadone or buprenorphine, relapse prevention with naltrexone, or counselling alone.

MAIN OUTCOME MEASURES

Completion of detoxification, engagement in post-detoxification treatment, and heroin use assessed at Days 8 and 91. Costs relevant to providing treatment, including staff time, medication use and diagnostic procedures, with abstinence from heroin use on Day 8 as the primary outcome measure.

RESULTS

There were no significant differences in the proportions completing detoxification (40/56 [71%] primary care v 46/59 [78%] clinic), participating in postwithdrawal treatment (28/56 [50%] primary care v 36/59 [61%] clinic), reporting no opiate use during the withdrawal period (13/56 [23%] primary care v 13/59 [22%] clinic), and in duration of postwithdrawal treatment by survival analysis. Most participants in both groups entered postwithdrawal buprenorphine maintenance. On an intention-to-treat basis, self-reported heroin use in the month before the Day 91 interview was significantly lower than at baseline (27 days/month at baseline, 14 days/month at Day 91; P < 0.001) and did not differ between groups. Buprenorphine detoxification in primary care was estimated to be $24 more expensive per patient than treatment at the clinic. The incremental cost-effectiveness ratio reveals that, in this context, it costs $20 to achieve a 1% improvement in outcome in primary care.

CONCLUSIONS

Buprenorphine-assisted detoxification from heroin in specialist clinic and primary care settings had similar efficacy and cost-effectiveness. Buprenorphine treatment can be initiated safely in primary care settings by trained GPs.

The general practitioner's role in AOD issues: overcoming individual, professional and systemic barriers

General practitioners (GPs) and increasingly other medical practitioners are well placed to address alcohol and other drug (AOD) problems. Their involvement in this area of care, however, is assessed to be less than optimal. There is, however, a growing body of evidence for the potential efficacy of medical practitioner intervention at the primary care, emergency department and in-patient level. There is also considerably expanded scope to operate from an evidence-based perspective. However, key questions arise regarding what constitutes best practice in the translation of the growing AOD knowledge base into clinical practice behaviours. This paper explores possible contributory factors to the low level of engagement with AOD issues by GPs and examines a wide range of individual, structural and systemic issues that may be amenable to change. Strategies for the dissemination of research findings, changing professional practice behaviour and introducing sustainable structural reforms are also addressed.

National Drug Policy: Implications of the Tough on Drugs' Ideology

Australia has emerged over the last decade as a world leader in drug policy. According to Single and Rohl (1997 pvii) Australia's National Drug Strategy 'has been characterised by a unique combination of features which have brought it international attention and acclaim'. The strength of Australia's policy has been its emphasis on both licit and illicit drugs, and also its clear articulation of harm minimisation as a guiding principle in all areas of action. The key policy goals recognised the harm associated with all substances and sought results in key areas of alcohol-related problems, tobacco-related problems, under-age consumption, prescription medication problems and illicit drug use. However, Australia has a new drug policy document for the new millennium, The National Drug Strategic Framework 1998 - 2002. As a result of a conservative influence in national politics, this framework has moved from the harm minimisation philosophy to a moralistic 'tough on drugs' philosophy that stresses zero tolerance, law enforcement and abstinence. There is a risk that Australia will experience an increase in adverse health, social and economic consequences as a result of this new policy direction. Nurses need to think critically about the 'tough on drugs' ideology. There is a risk that significant adverse affects may occur for their drug-using patients as a result of this policy change. In their practice, nurses need to challenge the validity of a punitive response, and to commit themselves to improving the health and safety of the illicit drug-using community.
