Treatment systems; Medical treatment

Seminal and key studies relating to local, regional and national systems for effectively and cost-effectively providing medical interventions and treatment in medical settings. Highlights a simple innovation which transformed detoxification recyclers into typical patients, asks if you agree with an expert group’s vision of what a good quality service looks like, and questions whether Britain is making progress on organising care for mentally ill problem drug users.

K Advancing recovery in US states (2012). In the US homeland of competition and private health care, it was cooperation and coordination which led to the introduction of new medications and innovations to promote continuing care – plus the exercise of regulatory and financial muscle and the salutary experience of senior staff who placed themselves in the patient’s shoes.

K No use-reduction effect after detoxification from stimulants (2014). Free source at the time of writing. Australian study finds a typically five-day inpatient detoxification no more effective than no treatment at all at reducing methamphetamine use among dependent users, most of whom injected the drug.

K Case management links detoxification to treatment (2006). Siting case managers there transformed detoxification services into gateways to longer term treatment and reduced repeat detoxifications. The initiative was part of a broader ‘recovery revolution’ in Philadelphia. Transitioning detoxification patients to follow-on treatment is associated (2014; free source at time of writing) with fewer readmissions and may be dependent on the links clinics have to follow-on services.

K No need to start methadone in specialist clinic before transfer to primary care (2014). From France the first study to randomly allocate patients to start methadone maintenance either in primary care or at a specialist centre found primary care more attractive to patients, and no less effective at reducing street-opioid use and promoting engagement and retention.

K Commission to enhance adherence to clinical guidelines (2008). Two sets of US methadone clinics selected for high versus low adherence to clinical guidelines provided evidence that in everyday practice, the recommended high doses and intensive psychosocial services really do make the intended difference to substance use and perhaps also to other outcomes. Findings suggest that commissioning to strengthen adherence to guidelines will improve outcomes. More on dose and psychosocial services in cell C3.

R Build opioid treatment system on buprenorphine to minimise medication-related deaths (2015). In England and Wales from 2007 to 2012, per prescription the overdose death rate involving buprenorphine was one sixth that of methadone. Implication is that a treatment system built on buprenorphine will be safer – as long as it attracts and retains enough patients.

R Evidence weak for integrating addiction and mental health treatment (2013; free summary and commentary from the US Centre for Reviews and Dissemination). Synthesis of research finds some evidence that integrating substance use and mental health treatment improves psychiatric symptoms and (in residential settings) drinking, but none of the slight advantages approached statistical significance, and only one of the studies assessed whether treatment truly was integrated. Study not included in review above. For discussion click and scroll down to highlighted heading. See also Effectiveness Bank hot topic on ‘dual diagnosis’.

R Pay-for-performance systems an evidential leap in the dark (Cochrane review, 2011). Overview of reviews on financial incentives for healthcare professionals in general could find no evaluations which reported on patient outcomes. Also conducted under rigorous Cochrane procedures, a similar review (2011) but of individual studies found “insufficient evidence to support or not support the use of financial incentives to improve the quality of primary health care”. A review (2014) specific to drug and alcohol treatment could find “no peer-reviewed evidence that [pay-for-performance] … improves client outcomes post-treatment”.

G NICE advises against specialist ‘dual diagnosis’ services ([UK] National Institute for Health and Care Excellence, 2016). The UK’s gatekeeper to the public provision of health interventions says that rather than creating specialist ‘dual diagnosis’ services, health and social care (including substance misuse) services should adapt to mentally ill substance users, and their care should be led by mental health services. Another NICE guideline (2011) has dealt specifically with psychosis and substance use. Guidance is reflected in NICE quality standards (2019).

G “No wrong door” (Public Health England, 2017). From the authority responsible for supporting substance use treatment in England, a strong statement that commissioners should ensure that co-occurring substance use and mental health problems are addressed as an integral part of all relevant local care pathways, and that this care is initiated no matter which service the patient first approaches.

What is this cell about? The roles of medical services and interventions within treatment systems for problem drug use implemented across an administrative area. In particular, their role in creating an effective and cost-effective mix of services offering attractive access points and appropriate options for moving between services or using them in parallel. Involves commissioning, contracting and purchasing decisions to meet local needs in the context of resource constraints and national policy. Activities include: assessing the need for different kinds of services; restructuring or re-tendering services; contractual requirements on services to demonstrate evidence-based practice, meet standards, and implement performance monitoring; and financial or other rewards/sanctions linked to activity, quality or outcomes.

Research on these functions is rarely of the ‘gold standard’ randomised-controlled-trial format, and work focusing on medical services is rare, but we can fall back on the studies and reviews in cell E2 which deal with the same topic across drug dependence treatment systems as a whole.

Where should I start? Perhaps with guidance listed above from the Joint Commissioning Panel for Mental Health, a collaboration led by England’s colleges for general practice and psychiatry. Published in 2013, it offered commissioning advice geared to the recovery and outcome-funding era, taking into account England’s national drug strategy, guidance and standards from NICE, the UK’s gatekeepers to the public provision of healthcare interventions, an expert consensus for the UK on medications as recovery aids (listed above), and guidance for England (listed above) on commissioning for recovery.

For the Joint Commissioning Panel, commissioning should be “outcome based” and “recognise recovery as central”. They also boldly specified what in their opinion a good drug and alcohol service would look like – of which more below.

Highlighted study What can you do with patients who cycle repeatedly through managed withdrawal from alcohol and/or drugs without getting anywhere in terms of their recovery from the underlying addiction? Listed above is our account of a simple idea from Philadelphia. Documented in a report listed above, the city is noted for the recovery-oriented transformation of its treatment system. At issue was how to make the most of the city’s detoxification centres, whose patients typically experienced multiple overlapping drug problems. For just over half these involved cocaine, nearly half alcohol, and around a third were using heroin. The most common combination was alcohol, cocaine and cannabis.

All too often detoxification was an isolated episode of care followed by relapse and then repeat detoxifications. The solution was to site clinical case managers at the centres to make contact with patients who had been cycling repeatedly through withdrawal, seemingly getting nowhere in terms of sustainably overcoming dependence. Case managers sought to motivate these patients to complete detoxification and (for at least a year) offered to guide and support them through the follow-on services needed to sustain their recovery. The effect was to transform revolving-door patients into patients with typical treatment admission patterns. Benefits were apparent across the entire caseload of the detoxification centres in increased capacity (the number of patients treated rose by well over a half), a halving in the proportion of admissions accounted for by repeated detoxifications, and an increase in successful referrals to longer term care.

The authors explained why their results mattered not just from a clinical perspective, but also from a health systems management perspective: “… repeated use of these expensive acute-care services was a major source of system inefficiency. Moreover, because detoxification and stabilization is a necessary first step for most publicly supported patients in their treatment episodes and some of these scarce detoxification beds were being re-occupied multiple times by a small group of [multiple-detoxification] patients, this inefficient, expensive utilization of the system had the additional perverse effect of reducing treatment access for other patients.”

This simple tactic offers one way to make a reality of the continuing care advocated by experts convened by UK medical colleges (listed above), seen as an essential element of recovery-oriented treatment which matches the chronic nature of the kinds of dependence/patients who present to treatment services. It would also improve a treatment system’s standing on the only performance measure recommended by the American Society of Addiction Medicine, described in the next section.

Issues to consider and discuss

What would a good quality drug service look like? Coming as it does from a heavyweight collaboration led by England’s colleges for general practice and psychiatry, a portrait painted in 2013 of what commissioners should look for in a drug (and/or alcohol) treatment service is not to be taken lightly. Take a look at the specifications on page 14 of the report listed above. Note that the list is subheaded, “Key components of a good quality service”; presumably the experts saw these as the minimum needed to justify a ‘good quality’ tag. On the following page you will find their recommended “Model of service delivery and core principles,” including: comprehensive assessment of patients’ needs going well beyond substance use problems; NICE-recommended substance use interventions and broader interventions to safeguard children and vulnerable adults and promote the welfare of carers and families; and assuring a competent and appropriately qualified workforce.

Is this also your vision of what quality consists of? It might help to look at the alternative set of criteria listed above (turn to pages 15–16 of the document) selected by a US expert panel as feasible, scientifically valid and unlikely to have unintended adverse consequences. Among the list are ‘process’ and ‘context’ measures like screening for related complaints and the proportions of patients prescribed medication and followed-up after detoxification. The effectiveness of these measures is to be assessed by a single ‘performance’ measure – the proportion of patients readmitted within three months of discharge for a further episode of inpatient or residential care. It was selected as an easily collected indicator of relapse or complications after initial treatment, interpretable as a direct outcome of poor coordination of services and/or an indirect outcome of poor continuity of services. Testing how to reduce this kind of readmission was the aim of the study from Philadelphia highlighted in the section above.

Discuss these criteria with colleagues, size up services in your area against them, and see how they square with your understanding of what makes for a good service. Here are some starter questions. Are these the attributes to be expected of each individual service, or (perhaps more realistically) of the local service network? Can we specify what constitutes a good quality service in isolation from the local service and case-mix context? Could good quality in one area be poor in another? Is this vision universally applicable, or particular to a certain kind of service – the “specialist integrated” teams staffed by “professional health and social care staff” which on page 15 the expert guidance for England listed above sees as the best model for addiction treatment? Were they right to imply that a specialist and professionally staffed service is the least anyone with severe substance use problems should expect? Do you also see this as the ideal? What of the GP-led services which in the national English NTORS study matched specialist clinics for outcomes?

The English report’s focus was on professional competence – obviously essential for safety, but is it a driver of recovery? Look back at the cell B3’s bite on practitioners in medical treatment. There we cite this advice from a review of why patients do better with one clinician than another: “Select and evaluate clinicians based on their ‘track record’ … assumptions that levels of training, experience, or other simple therapist variables could account for such differences [in effectiveness] does not hold.” In the same cell the Highlighted study section notes that the varying progress made by the patients of different methadone service counsellors could not be accounted for by their qualifications. Important instead were being administratively well organised and diligent, and building on this by being actively problem-solving and therapeutic.

Following the lead given to evaluate practitioners by their track records, why not do the same for whole services, and simply recognise what is or is not a good quality service by how well its patients do, regardless of what the service does or how it is staffed? That sounds very simple, but the (see documents listed above) reality has proved complicated and of unproven value.

Are we making progress on systems for treating ‘dual diagnosis’? At the turn of the millennium the aim at the top of government in the UK was not just to make progress, but huge strides in caring for people with both substance use and mental health problems, conventionally termed the ‘dual diagnosis’ caseload. Listed above, unambiguous policy issued in 2002 by England’s Department of Health on who should take the lead in caring for these patients stressed that when mental health problems are severe, care “should be delivered within mental health services,” which “have a responsibility to address the needs of people with a dual diagnosis”. At the heart of the policy was “mainstreaming”, meaning substance use was to be no excuse for patients with mental health diagnoses to be “shunted between different sets of services”. Achieving this objective required not just tinkering, but a “radical rethink of the way services are organised – they need to be organised around the user rather than around social, professional or service constructions of ‘abnormal’ behaviour”.

Though the rhetoric was missing, in 2011 and again in 2016, the stipulation that mental health services must take responsibility was echoed in guidance from NICE listed above. Similarly, in 2019 NICE saw the identification of a “care coordinator working in mental health services in the community [who] can liaise with the different services and act as a central point of contact for the person, their carers and service providers” as one criteria for good quality service provision for co-occurring severe mental illness and substance misuse.

In between came the unofficial but still authoritative commissioning advice for England discussed in the section above. Issued in 2013, it did not directly contradict official policy and guidance, but the emphasis seemed more on substance use services shouldering or sharing the load. For these authorities one sign of a high-quality substance use service was that it can “manage the full range of complexity of need, including … mental and associated physical health needs”. Funding bodies were encouraged to commission “services that recognise the connections and linkages between drug and alcohol misuse”. Coming from major charities and public service representative bodies coalescing in the Joint Commissioning Panel for Mental Health, it represented a significant recognition of the importance of substance use in mental health.

About what happened on the ground, there is little current information. At least initially, it seems the “radical rethink” called for in 2002’s health department policy did not materialise. In his foreword to the policy, Professor Louis Appleby, National Director of Mental Health, had been “confident it will be a very useful tool for developing effective services in the future”. But when in 2007 implementation was assessed (report listed above), in a second foreword he admitted there remained “a long way to go to genuinely meet the complex and changing needs of people with dual diagnosis”. A survey of the authorities and staff responsible for local implementation had showed that mental health services in England had not been able to adequately gear up for problem substance use among their caseloads. “Fundamental requirements for planning services such as monitoring service use and carrying out local needs assessments had been achieved only patchily.” For a policy intended to promote user-centred service provision, most revealing was that “Only two fifths of [local implementation teams] had collated evidence on user satisfaction with services.” The 2002 policy might have made sense in Whitehall, but in practice it was not working out.

Also in 2007, at a micro level some of the reasons for the steepness of the challenge became apparent in an article based on interviews with mental health nurses in the south of England. Despite (or perhaps, because of) their being practised in working with substance using clients, the difficulty of adequately responding was a prominent theme, prompted by a perceived lack of skills and support in the face of what was experienced as a hard-to-treat population: Working with people who have a dual diagnosis seemed like an “impossible challenge” “Working with people who have a dual diagnosis was thought to be hard, not often rewarding and often seeming like an impossible challenge.” Why “impossible”? Among the reasons were that “Clients were hard to engage and often appeared helpless and lacking in hope. Many clients are reluctant to accept help. Dually diagnosed people required long-term commitment in order to build trusting relationships and to establish enough contact with them over time. Community mental health nurses felt that they never had enough time to achieve their goals of care.” That dead-end word “impossible” will crop up again below, suggesting that these nurses were speaking for colleagues across the world.

The obstructions experienced by the nurses were classically of the kind training is unable to shift. Also published in 2007, that finding (see cell D2 of the Alcohol Treatment Matrix) emerged from a study in London of training for mental health staff in working with mentally ill substance users. Though the mental health case managers selected for the study had all attended at least four days of a five-day course and been offered monthly supervision, their patients could not be shown to have further reduced their substance use or to have subsequently required less hospital care.

These studies date from many years ago. With further new guidance and more experience, do today’s substance users find welcoming and effective care in mental health services? For problem drinkers, a survey conducted in England in 2014 suggests that the “failure to meet the needs of the dually diagnosed” remains, and may be worsening because mental health budgets have been cut, and services are now commissioned separately from substance use services.

The following year, Professor Liz Hughes, who has extensive clinical and academic experience in mental health, substance use, and in their co-occurrence, delivered a similar verdict under the banner, “The NHS is failing people with mental health and substance use problems.” Things were, she warned, no better now than in the 1990s; in some ways, worse. Again, budget cuts and commissioning processes and structures were spotlighted: “Since the localism agenda of the coalition government, and now the Conservative government, and the cuts to government central budgets, many of the national programmes have disappeared. This is further complicated by the almost complete transfer of substance use services to the third sector and the absence of mental health staff in these new services. Currently, dual diagnosis work is based on a postcode lottery, and is piecemeal at best.”

Britain is not alone in finding the engineering of even basically adequate care for mentally ill substance users an intractable task. In 2013 a review (listed above) of international research on treating serious mental illness and substance use sounded a “Mission impossible” warning in its title, explaining that “Treating adults with severe mental illness and substance use disorder has been considered ‘mission impossible’ [exemplifying] the challenges consumers confront in obtaining treatment for both disorders concurrently”. The term ‘impossible’ directly echoed the “impossible challenge” despair of mental health nurses in England described above. Nevertheless, in the next sentence the review insisted that “the challenge must be met” – “must” due to the substantial overlap (1 2) between mental illness and problem substance use and the serious consequences of failing to respond effectively to their co-occurrence.

“Must“ for the sake of the patients – but how? One opportunity came in 2016 in the form of the UK government’s Life Chances Fund. Announcing it, the then prime minister David Cameron said “up to £30 million” would be available “to encourage the development of new treatment options for alcoholism and drug addiction, delivered by expert charities and social enterprises”. Commenting on the policy, an independent Mental Health Taskforce said applicants should “demonstrate how they will integrate assessment, care and support for people with co-morbid substance misuse and mental health problems”. However, the central money was intended merely as a “top-up”; not just the ideas but most of the funding would have to raised locally. In the event, none of the grants were for improving core dual diagnosis care for adults and just one directly concerned this population – a project focused on frequent emergency department attendees with complex and multiple problems, including problem substance use.

Faced with this persistent and potentially very costly gap in service provision, rather than relying on mental health services, should we change tack in ways hinted at in 2013 in the document discussed above from a coalition of service providers in England? That might include helping substance use specialists take a more prominent role in supporting mental health services, perhaps even skilling up to themselves deal with more of the psychiatric problems so common among their caseloads. Or would that be counterproductive and possibly dangerous in cases of severe mental illness? Where should the line be drawn across which mental illness is too severe and/or of a type requiring mental health services to take the lead? If they are to take the lead, what can feasibly be done to enable mental health services to welcome and offer an appropriate response to patients whose condition is complicated by substance use? Was NICE right to so firmly close the door (“Do not create a specialist ‘dual diagnosis’ service”) on services dedicated to the overlap between substance use and mental health? Are these services the best way to meet the coalition’s call for “services that recognise the connections and linkages between drug and alcohol misuse”? Explored more fully in our hot topic on the issue, how best to deal with these crossover patients just does not seem to get any clearer.
