NTORS - Choose Maintenance or Detoxification, Not 'Reduction'

The patients who sought treatment in the NTORS methadone programmes presented with a range of serious and chronic drug misuse and other problems (Gossop et al., 2000). The most frequently reported drug problem involved dependence upon heroin, though the majority of patients were multiple drug misusers. After starting methadone treatment, the NTORS results showed a range of substantial reductions in problem behaviours. These were clearly shown in terms of reductions in use of heroin, non-prescribed methadone, and benzodiazepines, reduced injecting and sharing of injecting equipment, improvements in psychological health, and reductions in crime.

The prescribing of gradually reducing doses of methadone is one of the most widely used treatments in the UK. NTORS found several differences between methadone maintenance (MMT) and methadone reduction (MRT) programmes. The patients in MRT were more likely to receive low doses and had poorer retention rates (Gossop et al., 2001). Treatment retention has been found to be one of the most consistent predictors of favourable treatment outcomes. We also found that reduction programmes were frequently not delivered as intended. Whereas the majority (70%) of the patients allocated to maintenance on an intention-to-treat basis received methadone maintenance, only about a third (36%) of the patients allocated to MRT received reduction.

Many patients who failed to receive MRT as intended appeared to have received some form of maintenance (Gossop et al., 2001). The failure of almost two thirds of the MRT patients to receive reduction treatment as intended raises a number of questions for treatment providers and policy makers. If most of the patients for whom MRT is planned and started, subsequently have this treatment changed, this calls into question the appropriateness of either the initial treatment planning process or the treatment delivery process, or both. More troubling was the finding that where MRT was delivered as intended, it was associated with worse outcomes.

Several factors were found to lead to improved outcomes. These included the provision of services in addition to the administration of methadone. The frequency and content of counselling sessions, for example, was found to have both direct and indirect relationships with improved heroin use outcomes. We also found a direct inverse relationship between methadone dose and frequency of heroin use at 1 month follow-up. Although methadone dose was not directly related to 6 month heroin use outcomes, its indirect influence was reflected through the strong positive association between frequency of heroin use at 1 month and at 6 months. This is consistent with the results from other studies which suggest that events occurring very early in treatment can have an effect upon later outcomes. The clients' perceptions of, and engagement with programmes were found to be related to reduced frequency of heroin use outcomes. An important task of treatment should be to increase motivation and engagement of patients.

Two areas in which substance use outcomes gave rise to concern involved crack cocaine and alcohol. Although the majority of NTORS patients were primarily dependent upon heroin, a substantial minority (about one third) were also using crack at intake. In the NTORS sample, although there were increases both in the rates of abstinence from crack and reductions in the frequency of use between intake and 1 year, these improvements appeared to gradually dissipate over time. For example, by the time of the final (4-5 year) follow-up, the overall rates for crack use and the frequency of use had returned to about intake levels among the methadone patients. This result disguises different patterns of crack use among those who were using crack and those who were not using crack during the period prior to intake. Among those who were using crack at intake, levels of use were more than halved at all follow-up points. In contrast, among those who were not using crack at intake, there was a gradual increase in the use of this drug. For this reason, our results regarding use of crack cocaine should be interpreted not as indicating a tendency to relapse to pre-admission patterns among those who were already using this drug at intake, but as being largely driven by the initiation of crack use among those who were not using crack at intake.

For alcohol consumption, the outcomes were not satisfactory. At intake, a substantial minority of the methadone patients were drinking excessively. No change was found at any point during the follow-up period. Alcohol is an important but neglected component within of the substance use problems of drug misusers in treatment services. Chronic alcohol abuse is an important cause of medical complications among drug misusers, and alcohol use is linked to increased risk of overdose and mortality (Gossop et al., 2002). The poor drinking outcomes among the methadone patients is a matter which requires urgent attention by methadone treatment services.

Consultation & User Representation - Designing Services Users Want

Users are the ultimate consumers of drug treatment services but 80% of problematic drug users fail to access treatment

Consultation and user representation means involving users in the process of designing services that meet their needs. The benefits of user involvement and consultation include the provision of constructive involvement in the provision of services which users want; advocacy in the use of health and social services; user self-help & mutual support; dissemination of harm reduction messages through peer networks; and 'Intelligence' on new drug trends or problems.

There are two types of user consultation:

Barriers to meaningful consultation include a lack of open management and users consultation feeling "flavour of the day" or a "tack on" to attract funding. There can be a perceived lack of fairness between funding for professional user involvement workers while drug user self-organisations are left struggling with inadequate resources and expected to offer time on voluntary basis. Professionals are often seen as controlling the agenda. Where users feel tied to an agency agenda, they feel they can only contribute to the benefit of the agency staff as opposed to the benefits for users. Users often feel unable to criticise or challenge for fear that they may be subject to sanctions. This can be compounded by the adversarial nature of some drug services. A leap of faith is required in acknowledging that users views are valid. 'Many users have trust issues with professionals. When things go wrong, or the results of the consultation process never see the light of day, then this further distances users from professionals; feeling that consultation is nothing more than an exercise in box ticking leading to reluctance to get involved again.

"Many sponsors would be more likely to support the right of the constituent group if such autonomy did not pose a threat to their own survival and developmental needs'
- Brager et al (1986) 'Community Organising'

There are two different possible outcomes of user consultation:

Mechanisms to increase user consultation include: methods to gaining informal comments such as a comments/suggestions box; or more formal user complaints procedures; satisfaction surveys; management committee places; an open management and staff culture that encourages agency service user groups to 'feed' their views upwards; places on DAT commissioning teams. Methods to include user groups who are not accessing services can include involvement in resource production (writing/designing leaflets/websites) and involvement in development and review processes. Approaches to removing the barriers can include giving incentives or payments that demonstrate value for users contribution to the consultation process. Regular feedback or progress reports that show what changes are taking place as a result of the consultation are invaluable.

Professional services need to redefine their relationships with users and manage this transition with care and sensitivity. Recognising the need to reconcile difficult and often conflict based issues. Recognising that the invitation to be consulted on their services, is for many users, the first opportunity for rebuilding trust! Effective consultation works when the barriers are removed and Users can see change happening and how they and other users have contributed. User self esteem improves as a result as they feel 'involved' and valued rather than passive recipients.

The National Drug Users Development Agency is run by and for drug users whose member groups include a wide range of drug groups working in local areas and in the national arena. It facilitates representation at national and regional level supporting information sharing, consultation and engagement of wider services through use of the population and the drug using community as a whole. It aims to support and facilitate best practice of drug user self-organisation in all its forms. It is available to local services or Drug Action Teams on a paid consultancy basis.

Buprenorphine In Primary Care: Summary

What is it, how to start it and how to use it
February 2003

Buprenorphine is a useful alternative for opioid dependent people. It widens the choice for opiate users who do not want methadone or who are intolerant to it. It is a useful addition for substitute medication, but not if the patient is stabilised and doing well on methadone and may be considered as a first choice for people dependent on opioids who wish to become opiate free.

Viewpoint - Should GPs be Involved in Criminal Justice Work?

Accepting Reality - The GP And The Criminal Justice System

The updated drugs strategy continues to place an emphasis on breaking the link between drugs and crime. Dr Linda Harris reviews the evidence and argues the case for the need to develop innovative partnerships with the criminal justice system.

The introduction of the 1999 Clinical Guidelines and the Government's ten-year strategy has shifted the public health message from an emphasis on harm reduction and maintenance of health status to more of one of social control and crime reduction. For some GPs this is fundamental worry. Drug Treatment and Testing Orders (DTTOs) have now become an established community sentence and the government has set a target of an increase in completed orders by 50% from April 2003. This is against a backdrop of planned mergers between Drug Action teams and Crime Reduction Partnerships. Police and probation, already contribute to the pooled treatment budget and therefore have responsibility and a vested interest in the performance and efficacy of local arrest referral and DTTO schemes.

For the first time this year new monies from criminal justice agencies will feed directly into the pooled budget enabling treatment providers to expand criminal justice treatment programmes in line with the revised targets in the government's updated drugs strategy. Clinicians are tasked with ensuring that there is equity between coercive and non coercive treatment services in terms of access, choice and quality, a challenge that is becoming increasingly difficult as resources focus more and more on breaking the drug-crime link and reducing recidivism.

Over the years Wakefield has gained a reputation for good partnership working with the criminal justice system. West Yorkshire was the professional homeland of Keith Hellawell, the ill-fated Drugs Tsar and the Wakefield STEP Project, based on the Miami Drug Court model was granted "Beacon" status superseding DTTOs and using the flexibilities of the 1A6 probation order to effect change. The 1A6 came with conditions of treatment but it did not stipulate the hours of contact in treatment or that testing HAD to be part of the order. The Wakefield Substance Misuse Strategy endorses the expansion of partnerships between drug treatment services and criminal justice and we have recently secured funding for a six-month pilot scheme targeting prolific shop thieves.

The funding will be used to expand our arrest referral team and covers the provision of additional police hours to enable them to outreach into the community. The police will be working with clients known to be committing crimes to fund their habit but who have yet to be charged for such offences. If the client is agreeable and deemed willing to engage with services, the police will liase with a dedicated treatment worker and actually transport the clients to their assessment appointment. Clients who fail to engage with treatment services in accordance with the Community Drugwatch treatment contract will be discharged from the treatment clinic and the police officers involved will be informed. Clients will be signposted towards the nearest community treatment team where they will be able to join the waiting list if they so wish.

Benefits - Local police intelligence indicates that many users fund their habit through retail crime and whilst many such individuals manage to avoid arrest, it is a matter of time before they are caught and held up before the courts. In the meantime they continue to participate in daily criminal activity with negative effects on public safety, family harmony and the local economy. If the project is successful there is a potential "win-win" situation for retailers and therefore we are looking for commitment from local stores to subsidise the scheme in order to secure its future. Ownership of schemes such as this by police, retail outlets and treatment providers illustrate the need to for a shared responsibility of society's drug problems and also feed into government strategies such Neighbourhood Renewal.

Constraints - In common with other schemes that fast track clients committing crime over more "law abiding" users, this project is open to criticism. Fast-tracking clients indirectly relieves pressure on waiting times for non-coercive treatment programmes but the survival of scheme's such as this is highly dependent on good outcome data such that strict entry criteria will have to be applied. This means the inevitable targeting of only those clients who are highly motivated and willing to enter a detoxification programme overlooking once again, those clients with more complex needs where a harm reduction approach with a focus on health needs is more suited.

A happy marriage between health and criminal justice? It is fair to say that the UK experience of coercive treatment has concentrated on reductions in acquisitive crime and drug-spend. A doctor's role is fundamentally about improving health, which makes a transition into coercive work problematic in terms of role and doctor patient relationship. Many senior police officers wish to see a blurring of the boundaries between community safety and client care and whilst it is laudable to seek to break cycles of crime and split the vulnerable from the organised criminal their desire to gain "intelligence" from such clients could create a controversial situation for the treatment providers working closely with them. As yet there appears to have been no exploration of the possible impact of coercion on the doctor patient relationship and indeed whether or not this change has had any effect either positively or negatively on psychosocial treatment outcomes. Increasingly GPs are extending their role and becoming commissioners and managers of services, a role that demands securing the maximum funding for their services including funding from the CJS.

Despite this the message from Government leads us to speculate on a future for primary care treatment providers where social policy and reform depends increasingly on marriages between health and criminal justice and where providers must capitalise on any new investments regardless of source and develop services that meet the government's strategic targets. Debates around the potential threats (and opportunities) of a marriage between health and criminal justice have so far failed to consider their implications for healthcare professionals and patients. Whilst interventions aimed at breaking the drug crime link continue to be attractive to commissioners there has been a disproportionate investment in research and evaluation that will produce the evidence base to support criminal justice partnership models over harm reduction.

My personal experience of initiatives that aim to break the drug crime link is one of the positive benefits of partnership working, namely a greater understanding of each other's roles and responsibilities in the prevention and treatment of drug misuse. Criminal justice research outcomes demonstrate improved efficacy but perhaps we will only be in a position to silence the critics when we have well-designed and randomised controlled studies focussing on psychosocial outcomes delivered in a criminal justice framework. Maintaining the integrity of our "health role" is challenging given the realities of commissioning, planning and providing care within the framework of the Government's ten-year strategy. Models of Care - widely supported by the treatment community draws on key policy documents, which include those focussing on the criminal Justice system. We must all be "compliant" with Models of Care and will be performance monitored accordingly. Perhaps the missing link is the piece of research or audit that demonstrates the added value in terms of bio-psychosocial milestones of the treatment interventions delivered in partnership with the Criminal Justice agencies.

Viewpoint - What Makes for Good Pharmacy Involvement?

I am a locum pharmacist and also a researcher. I have worked in a specialist drugs agency and have locumed in many pharmacies that provide both needle exchange and dispensing for drug users. I work with drug users for many reasons. Professionally I consider I have a duty of care to all members of the public and cannot discriminate between who 'deserves' and who doesn't. I can back this up with the first principle of our code of ethics which states that my prime concern must be for the welfare of the patient and the public. Providing services to drug users benefits both the patient and the public enormously. There is a huge and very strong evidence base for both needle exchange and maintenance therapy, in terms of promoting health and, in the case of maintenance, reducing drug related crime. Few other healthcare interventions can produce such dramatic and wide-reaching results.

Working with drug users is incredibly rewarding and fair to say relatively easy. Community pharmacists don't really get such close contact and ongoing follow-up with any other patient group. We tend to see people sporadically and never really get the luxury of knowing the outcomes from our advice or interventions. Working with drug users is different, often we see them every day. We see people become healthier as they continue on maintenance treatment. Over time, a rapport develops between yourself and the drug user, which allows you privileged insight into the life and well being of the individual. The difference that maintenance treatment makes to the lives not only of the drug user, but their families too, becomes very apparent and it is truly rewarding to know that you have been part of that process.

Community pharmacists often struggle with working in isolation and complain about a lack of professional respect from GPs. In my experience, working with drug users brings you closer to GPs, allowing you to share your professional experience and advising each other on a level playing field. Clinically, it is not generally a complex area to work in and with a sound knowledge of pharmacology and therapeutics, it is an area where the pharmacist's expertise can be of great value to the prescribing team and the client - for example advising on over-the-counter medicines which may give false positive urine tests.

I particularly enjoy working with needle exchange clients. Often people who use pharmacy based needle exchanges are new injectors and people who don't access other services. This means that I might be the only healthcare professional that the client ever has contact with. This means my role in encouraging people to use specialist services and access treatment is key, as is my role in promoting responsible disposal and returns. It also means I have to be competent in providing safer injecting advice and injection site injury advice. Again this means undertaking Continuing Professional Development and developing good working relationships with specialist drugs services and A&E departments, so I don't send drug users for inappropriate or unwelcoming care.

Pharmacists are often scared of working with drug users, many may not have knowingly met a drug user before and all the stereotypes and scare mongering that we see in the media informs their views. Although I was worried before I started working in this area, in my experience few of these stereotypes are ever upheld. Drug users are in the main nice people who are usually very grateful for the services you provide. I have not experienced any difficulties that cannot be ironed out. The key is to treat drug users like any other pharmacy client, with respect and courtesy, which is almost always returned. When I left my last job I was overwhelmed by the cards, flowers and good wishes that my drug users gave to me. It is in my view the most rewarding area of pharmacy practice.

Classics Revisited - Heroin Addiction & Drug Policy, The British System

Strang, J and Gossop, M (ed)
Oxford Medical Press 1994

This classic text is a must for anyone who wants to understand the history and development of the British drug treatment system. The different aspects of an eclectic system of treatment provision are put into perspective by the leading authors in the field at the time. From a community prescribing perspective there is a very informative chapter by Bing Spear charting the history of prescribing policy. This describes how the activities of one doctor, Lady Frankau, almost single handedly persuaded the second Brain Committee to recommend that prescribing be taken out of the hands of GPs and that special clinics be set up run by psychiatrists with home office licenses (heroin was the main drug prescribed at that time). "The 'psychiatrizing' of addiction treatment policy in the UK was assured", he concludes.

In subsequent chapters the progress of these new clinics is charted as is the shift to oral methadone prescribing, often on a reducing basis, as psychotherapeutic interventions became preferred. The journey then takes us through the 1980's and the attempt to create a more community based approach with the advent of CDTs and their remit to re-engage GPs and other professionals in treatment. This largely failed as team members took on casework rather than facilitation. As a parallel story a chapter by Alan Glanz charts in detail 'The Fall and Rise of the General Practitioner' both in drug dependency treatment but in the context of a general fall and rise in the NHS.

The book generally gives the most comprehensive and authentic resume to date of the very unsystematic 'British System'. Fascinating for anyone interested in history but also essential for understanding the system within which we work.

Review of Recent Papers, Articles & Reports

1. Factors associated with abstinence, lapse or relapse to heroin use after residential treatment: protective effect of coping responses

Gossop, M. et al.
Addiction 97; 1259-1267.

This technical paper from the NTORS team investigates factors associated with abstinence, lapse or relapse to heroin use after residential treatment. Specifically, the extent to which changes in cognitive, avoidance and distraction coping responses were related to heroin use and other drug use outcomes. Data on client characteristics and problems, coping responses, drug use and other outcomes, were collected by structured face-to-face interviews. 242 clients from 15 residential rehabilitation programmes and 8 in-patient units in the NTORS project, who used heroin before treatment and who were followed-up after treatment during the first 12 months of the study.

2. General practice management of illicit drug users in Scotland: a national survey

C. Matherson, J. Pitcairn, C.M. Bond, E. Van Teijlingen & M. Ryan
Addiction 2003; 98. 119-126.

This is a cross- sectional randomised structured postal questionnaire survey. It aims to describe the level of involvement of general practitioners in the management of illicit drug dependency; the nature of current practice in the management of illicit drug dependency; the influence of guidelines on practice; GP training experience and needs; to consider the policy implications of the findings. It achieved 63% response rate with 60% of respondents treating drug users. 51.5% provided methadone maintenance but only 58% used doses in the recommended range. Maintenance prescribing of dihydrocodeine and benzodiazepines was provided by 24% and 44.8% of respondents respectively. 79.3% had received the national Clinical Guidelines, but only 22.5% believed this had influenced their practice. Only a third of respondents had received drug dependency training. Beliefs about drug dependency being part of a GP professional remit were split. Relatively high involvement with drug users with methadone maintenance was the most common treatment provided. Maintenance prescribing of dihydrocodeine and benzodiazepines were common despite a lack of clinical evidence supporting the effectiveness of these treatments. This possibly reflected the nature of presenting drug problems and highlighted the difficulties some GPs may face in the managing of multiple drug dependencies within current guidelines. Further local training to implement guidelines along with trials of alternative treatments currently outside of the Clinical Guidelines should be considered.

Dr Fixit's Advice - Alcohol Relapse

Dr Fixit

Question

Ted came to see me saying he had started to drink again after a party. He stated he had previously had "drink problem", but had not drunk for 9 months following a hospital detoxification and counselling. He had now been drinking again for the past 3 weeks, about half a bottle of whiskey (+/-15units)/day. He is very keen to stop and get back to work (he has been off for 3 weeks). He feels he does not need hospital treatment again but has felt unwell when he has tried to stop and wants me to prescribe something for him. He lives with his wife who is supportive. How should I proceed?

Answer

The first things to do are the standards - take a history and do an examination. We need to find out about Ted's drinking history in more detail - for how long and how much had he been drinking in the past, had he had more detoxifications than the one you mention and if so, where had they taken place, how many times, and with what outcomes. Has he had any physical sequelae of his alcohol intake? Particularly relevant at this point are a history of withdrawal fits, liver disease or DTs. How has his mental health been and was the recent lapse secondary only to the temptation offered by the office party or have been there been other recent stresses in Ted's life? Although he appears committed would like to assess this in more depth. We need to know something about his health over the last 3 weeks too - has he tried to stop himself and been unable? A physical examination should be undertaken with exclusion of jaundice, ascites or cardiac complications.

At some point during this first consultation, I would want to explore Ted's attitude to this "relapse". He may be feeling very guilty, with profound sense of failure. I would try to refer to the last 3 weeks as a lapse, and explain that it should be possible to prevent this becoming a full-blown relapse. It is often possible to use a lapse following abstinence to look at triggers for drinking and devise avoidance strategies for the future.

Next we need to find out what Ted is expecting the 'something prescribed' to be. He has had some experience of detox in the past and may be quite knowledgeable. The main aims of prescribing in alcohol detox are symptomatic relief and prevention of withdrawal fits. These can be achieved by prescribing a reducing dose of chlordiazepoxide, over a 8-10 -day period. A possible regime would be:

Chlordiazepoxide 30mgs (*20mgs) QDS for 2 days (*female dose)
Chlordiazepoxide 20mgs (*15mgs) QDS for 2 days
Chlordiazepoxide 10mgs (*10mgs) QDS for 2 days
Chlordiazepoxide 5mgs (*5mgs) QDS for 2 days - then stop

It is never acceptable to prescribe chlormethiazole (Heminevrin) to an outpatient, or as part of a community detox.

Vitamin deficiencies also need to be addressed and it is usual to also give thiamine although Ted is probable OK because of his short history.

Ted is complaining of symptoms so needs help with stopping safely. He has requested detox at home and this would be worth attempting. He has insight, support from his wife and a job to go back to so is a good candidate for home detox. He may need additional support and this can often be provided by a home detox nurse from the local alcohol service. Ted should be advised that the first 2-3 days will be the most uncomfortable. He should be advised that he may feel thirsty and will probably have difficulty in sleeping, but that these symptoms will resolve. After 8-10 days, the worst of Ted's withdrawal symptoms should be over and he will be able to stop his chlordiazepoxide. He may still be sleeping poorly, however, and needs to be reassured that this is normal and may take up to 3 months to resolve. I often prescribe amitriptylline at this point, if simple sleep hygiene measures are not working. It is important to avoid benzodiazepines and zopiclone.

Once through his detox, Ted is going to need ongoing support and relapse prevention. You can do some of this work but try to engage him with an alcohol counsellor or addictions therapist, who can help Ted explore the triggers to his drinking and adopt avoidance strategies. Some alcohol-dependent patients find support from Alcoholics Anonymous, which is a self-help group. Ted's wife may find Families Anonymous for friends and family of alcohol users useful. Psychosocial support may be accompanied by prescribing aimed at preventing a return to drinking. Two agents are available: disulfiram (Antabuse) and acamprosate (Campral). See box below. In summary, Ted should do well - he is motivated, with a short history, a previous period of not drinking and he has support. If he didn't have these, then it would be important to look for in-patient detox. Don't forget that the detox is a stage and not an endpoint. It is essential that any approach to alcohol dependency should involve holistic psychosocial intervention.

Acamprosate (Campral EC)

Disulfiram 200mgs (Antabuse)

Dr Fixit's Advice - Buprenorphine for Detox

Dr Fixit

Question

John who is 22 years old has been using drugs, mainly heroin since he was 17. He also drank 20-30 units per week, took crack up to twice a week and non-prescribed diazepam when available. He first presented to me aged 19 years and always wanted to become drug free. I have been treating him from the beginning and he has attempted two community detoxes with methadone and two hospital detoxes with lofexidine, but he relapsed onto heroin before completion on each occasion. He had been on methadone maintenance for 6 months and has now again chosen to be on reduction. He had always resisted the option of residential rehabilitation but now wants to go and wants to detox prior to going. He is currently on 30 mg of methadone, he is not using on top and his urine is negative for all except methadone. I would like to use buprenorphine but I have not prescribed it before. How would I proceed?

Answer

Buprenorphine is potentially a good choice for John as many patients describe a milder withdrawal process when reducing buprenorphine than with methadone - given that he has had difficulties reducing off methadone in the past. He and you have got to a good point to transfer to buprenorphine. Transferring from 30mg methadone is rarely a problem. People get anxious about starting something new so explain the drug fully to him (and a carer if possible). Emphasise possible transient side effects (e.g. headache, nausea, disturbed sleep, metallic taste) and the need and reasons for taking the medication sublingually (lower bioavailability if taken orally). Explain the likelihood that it may take a few days for him to feel comfortable on buprenorphine. To start him off, stop the methadone and ask him to wait at least 24hrs until he is experiencing mild withdrawals.

The longer he waits the easier it is. Ask him to take 4mgs (2x2mgs tablets) of buprenorphine sublingually and review him after 24 hrs. Increase the daily dose to 6 or 8 mg, with subsequent dose increases if required (patients transferring from 30mg methadone rarely need more than 12mg buprenorphine). Stabilise him on that dose for a few days then reduce by 2mg/week until 2mg is reached. This reduction can be made faster or slower depending on the patient. At 2mg change to 0.4mg tablets and give x3 (1.2mg) for a week, x2 (0.8mg) for a further week and x1 (0.4mg) for one week. Try and arrange for this final week to be undertaken just before (or in) rehab so he is not vulnerable in the community. Most patients will describe only mild withdrawal discomfort when stopping buprenorphine using such a slow reduction regime, although some patients may complain of sufficient withdrawal discomfort to warrant symptomatic medication for a few days (e.g. lofexidine). Be prepared to see him at any time and don't forget to give him a patient leaflet (see Articles section for downloads).

Hot Topics - RCGP Regional Clinical GP Leads

The Royal College of General Practitioners (RCGP) has recently appointed a number of GP Regional Clinical Leads whose role will be to support local primary care organisations in developing capacity for drug misuse services in primary care. The Regional Clinical Lead posts have been created to support, direct, influence and contribute to the development of the Drugs Training Programme at regional level.

Hot Topics - New Guidance For GPwSIs

RCGP Guidelines For The Appointment Of General Practitioners With Special Interests (GPwSI) in the Delivery of Clinical Services
April 2003 (Commissioned by the Department of Health)

The General Practitioner with Special Interest (GPwSI) should be seen as one option available to primary care organisations and must be part of a co-ordinated approach to treatment services and not seen merely as a pragmatic solution to dealing with waiting lists. A GPwSI service must not be seen as a substitute to a specialist service. Where a specialist provider is not in place then the PCO must ensure that a suitably trained practitioner fills this gap, rather than using the GPwSI as a substitute. Examples of core activities of a GPwSI service include clinical, education and liaison, service development and leadership. With regards to providing a clinical service for patients with drug misuse, these services can be offered either as part of an integrated general practice service with care being provided alongside other general medical services or as a stand-alone service. A stand alone service may be located within a dedicated drug misuse service within the NHS (primary or secondary care) or other provider and either targeted to a particular population or risk group (e.g. pregnant users, hard-to-reach groups,) or provided as part of a generic drug misuse service.

These guidelines are available in full at http://www.doh.gov.uk/pricare/gp-specialinterests/drugmisuse.pdf and can be read in conjunction with the Modernisation Agency's Practitioners with Special Interests.
