Short-Term Outcomes for Opiate and Crack Users Accessing Treatment: The Effects of Criminal Justice Referral and Crack Use.

BACKGROUND/AIMS: The English drug treatment population doubled in size between 1998 and 2008, increasingly characterised by crack cocaine use and criminal justice system (CJS) referral. We assessed short-term (median 3.5 month) behaviour changes following participation in drug treatment and the moderating effect of CJS referral/crack use. METHODS: Opiate and/or crack cocaine users (n = 1,267) were recruited from 342 agencies. Outcome effects were assessed via interaction term regression, clustered at participant level, controlling for client characteristics. Treatment retention effects were tested via Cox proportional hazard models. RESULTS: Statistically significant improvements in health, drug use and offensive behaviour were observed (e.g. heroin use from 87 to 51%, acquisitive offending from 47 to 23%). Referral route was not associated with variation in outcomes. Crack use at baseline was associated with a greater chance of non-fatal overdose at follow-up (p = 0.035, 95% CI 1.08-8.20) but a greater reduction in offending income (p = 0.002, 95% CI £104-£419). CONCLUSION: Despite changes in the English drug treatment population, equivalent short-term improvements in client behaviour were observed a decade earlier. Outcomes for CJS-referred clients were comparable to non-CJS. Crack use at treatment entry offered some scope for greater improvements in offending but may be a barrier to cessation of mortality-associated risky behaviour.

Do marketing and alcohol treatment/public health experts think televised alcohol advertisements abide by regulatory guidelines?

Televised alcohol advertisements in the United Kingdom must abide by the Broadcast Committee of Advertising Practice Code, which provides guidelines concerning advertisements not implying, condoning or encouraging immoderate, irresponsible or antisocial drinking. Previously, 75 per cent of 373 general public respondents were shown one of seven advertisements rated a breach of at least one guideline. This study assessed whether experts in marketing (n = 25) and alcohol treatment/public health (n = 25) perceived the same seven television alcohol advertisements as complying with the Broadcast Committee of Advertising Practice Code. Overall, 83 per cent of advertisements were rated as breaching at least one guideline. This provides further proof that self-regulatory alcohol guidelines are not fit for purpose.

Modeling the Potential Impact of Changing Access Rates to Specialist Treatment for Alcohol Dependence for Local Authorities in England: The Specialist Treatment for Alcohol Model (STreAM).

OBJECTIVE: We modeled the impact of changing Specialist Treatment Access Rates to different treatment pathways on the future prevalence of alcohol dependence, treatment outcomes, service capacity, costs, and mortality. METHOD: Local Authority numbers and the prevalence of people "potentially in need of assessment for and treatment in specialist services for alcohol dependence" (PINASTFAD) are estimated by mild, moderate, severe, and complex needs. Administrative data were used to estimate the Specialist Treatment Access Rate per PINASTFAD person and classify 22 different treatment pathways. Other model inputs include natural remission, relapse after treatment, service costs, and mortality rates. "What-if" analyses assess changes to Specialist Treatment Access Rates and treatment pathways. Model outputs include the numbers and prevalence of people who are PINASTFAD, numbers treated by 22 pathways, outcomes (successful completion with abstinence, successfully moderated nonproblematic drinking, re-treatment within 6 months, dropout, transfer, custody), mortality rates, capacity requirements (numbers in contact with community services or staying in residential or inpatient places), total treatment costs, and general health care savings. Five scenarios illustrate functionality: (a) no change, (b) achieve access rates at the 70th percentile nationally, (c) increase access by 25%, (d) increase access to Scotland rate, and (e) reduce access by 25%. RESULTS: At baseline, 14,581 people are PINASTFAD (2.43% of adults) and the Specialist Treatment Access Rate is 10.84%. The 5-year impact of scenarios on PINASTFAD numbers (vs. no change) are (B) reduced by 191 (-1.3%), (C) reduced by 477 (-3.3%), (D) reduced by almost 2,800 (-19.2%), and (E) increased by 533 (+3.6%). The relative impact is similar for other outputs. CONCLUSIONS: Decision makers can estimate the potential impact of changing Specialist Treatment Access Rates for alcohol dependence.

The role of the early therapeutic alliance in predicting drug treatment dropout.

BACKGROUND: To investigate the role of the therapeutic alliance in predicting length of retention in residential drug treatment. METHODS: The study recruited 187 clients starting residential rehabilitation treatment for drug misuse in three UK services. Counsellor and client information was assessed at intake, and the average total scores of client and counsellor ratings on the WAI-S (obtained during weeks 1-3) were use as the alliance measure. Length of retention and treatment completion (stay beyond 90 days) were used as measures of retention. RESULTS: Clients with weak counsellor rated alliances dropped out of treatment significantly sooner than clients with strong counsellor rated therapeutic alliances, whether or not the model adjusted for individual counsellor effects and potential confounders including psychological well-being, treatment motivation and readiness, coping strategies, and attachment style. The client rated alliance did not predict length of retention. Apart from the alliance, pre-treatment crack use, secure attachment style and better coping strategies were associated with shorter retention, whereas greater confidence in treatment, older client age and better education predicted treatment completion. Counsellors with greater experience of delivering drug counselling retained clients longer. CONCLUSIONS: The findings of this study stress the importance of treatment professionals attending to the therapeutic alliance in drug treatment, as counsellors' alliance ratings were found to be amongst the strongest predictors of dropout. Using alliance measures as clinical tools may help treatment practitioners to become aware of the risk of disengagement early on. Prospective studies are needed to evaluate whether strategies of reallocating clients with poor alliances to different counsellors lead to improvements in retention.

The role of the therapeutic alliance in the treatment of substance misuse: a critical review of the literature.

BACKGROUND: In the past two decades, a number of studies investigating the role of the therapeutic alliance in drug treatment have been published and it is timely that their findings are brought together in a comprehensive review. AIMS: This paper has two principal aims: (1) to assess the degree to which the relationship between drug user and counsellor predicts treatment outcome and (2) to examine critically the evidence on determinants of the quality of the alliance. METHODS: Peer-reviewed research located through the literature databases Medline, PsycInfo and Ovid Full Text Mental Health Journals using predefined search-terms and published in the past 20 years is considered. Further papers were identified from the bibliographies of relevant publications. FINDINGS: A key finding is that the early therapeutic alliance appears to be a consistent predictor of engagement and retention in drug treatment. With regard to other treatment outcomes, the early alliance appears to influence early improvements during treatment, but it is an inconsistent predictor of post-treatment outcomes. There is relatively little research on the determinants of the alliance. In studies that are available, clients' demographic or diagnostic pre-treatment characteristics did not appear to predict the therapeutic alliance, whereas modest but consistent relationships were reported for motivation, treatment readiness and positive previous treatment experiences. CONCLUSIONS: The therapeutic alliance plays an important role in predicting drug treatment process outcomes, but too little is known about what determines the quality of the relationship between drug users and counsellors.

Predicting the early therapeutic alliance in the treatment of drug misuse.

AIMS: To predict the early therapeutic alliance from a range of potentially relevant factors, including clients' social relationships, motivation and psychological resources, and counsellors' professional experience and ex-user status. DESIGN: The study recruited 187 clients starting residential rehabilitation treatment for drug misuse in three UK services. Counsellor and client information was assessed at intake, and client and counsellor ratings of the alliance were obtained during weeks 1, 2 and 3. MEASUREMENTS: The intake assessment battery included scales on psychological wellbeing, treatment motivation, coping strategies and attachment style. Client and counsellor versions of the Working Alliance Inventory (WAI-S) were used for weekly alliance measurement. Hierarchical linear models were used to examine the relationship between alliance and predictor variables. FINDINGS: Clients who had better motivation, coping strategies, social support and a secure attachment style were more likely to develop good alliances. Findings with regard to counsellor characteristics were not clear cut: clients rated their relationships with ex-user counsellors, experienced counsellors and male counsellors as better, but more experienced counsellors rated their alliances as worse. CONCLUSIONS: The findings offer important leads as to what interventions might improve the therapeutic alliance. Further work will need to establish whether the therapeutic alliance and ultimately treatment outcomes can be enhanced by working on improving clients' motivation and psychosocial resources.

Prevalence and factors associated with sex trading in the year prior to entering treatment for drug misuse in England.

BACKGROUND: This study estimates the past year prevalence of and factors associated with sex trading (offering sex for money, drugs or something else) among 1796 men and women presenting to 342 drug misuse treatment agencies in England, and identifies service development and delivery implications. METHODS: Secondary analysis of baseline data from a prospective cohort was conducted. Short Form-12 measured mental and physical wellbeing, psychiatric diagnoses were self-reported and the circumstances, motivation and readiness tool assessed readiness for/pressure to enter treatment. Logistic regression models determined associations with sex trading separately by sex. Inverse probability population weights were calculated, utilising demographics from the National Drug Treatment Monitoring System and agency specific data collection windows. RESULTS: The estimated prevalence rate of sex trading in the past 12 months was 5.1% (15.0% for women and 2.1% for men). For women, adjusted models identified crack use (aOR 1.83, 95% CI 1.22-2.74, p=0.004), previous treatment (aOR 3.00, 95% CI 1.31-6.86, p=0.010) and greater readiness for treatment (aOR 1.12, 95% CI 1.01-1.24, p=0.027) as independently associated with sex trading. For men, lower mental wellbeing (aOR 0.97, 95% CI 0.94-0.99, p=0.030) was independently associated and marginal effects were identified for syringe sharing (aOR 2.89, 95% CI 0.94-8.86, p=0.064) and unprotected sex (aOR 2.23, 95% CI 0.95-5.26, p=0.065). CONCLUSIONS: Sex trading among drug misusers is associated with additional health risks and specific treatment needs. Given the scale of the problem it is important that treatment providers have the competencies to adequately address the issue and provide accessible and appropriate services.

The impact of paying treatment providers for outcomes: difference-in-differences analysis of the 'payment by results for drugs recovery' pilot.

AIMS: To estimate the effect on drug misuse treatment completion of a pilot scheme to pay service providers according to rates of recovery. DESIGN: A controlled, quasi-experimental (difference-in-differences) observational study using multi-level random effects logistic regression. SETTING: Drug misuse treatment providers in all 149 commissioning areas in England in the financial years 2011-12 and 2012-13. PARTICIPANTS: Service users treated in England in 2011-12 and 2012-13. INTERVENTION AND COMPARATORS: Linkage of provider payments to performance indicators in eight pilot commissioning areas in England compared with all 141 non-pilot commissioning areas in England. MEASUREMENTS: Recovery was measured by successful completion of treatment (free from drugs of dependence) and engagement with services was measured by rates of declining to continue with treatment. FINDINGS: Following the introduction of the pilot scheme, service users treated in pilot areas were 1.3 percentage points [odds ratio (OR) = 0.859; 95% confidence interval (CI) = 0.788, 0.937] less likely to complete treatment compared with those treated in comparison areas. Service users treated in pilot areas were 0.9 percentage points (OR = 2.934; 95% CI = 2.094, 4.113) more likely to decline to continue with treatment compared with those treated in comparison areas. CONCLUSIONS: In the first year of the pilot 'Payment by Results for Drugs Recovery' scheme in England, linking payments to outcomes reduced the probability of completing drug misuse treatment and increased the proportion service users declining to continue with treatment.

The effectiveness and cost-effectiveness of diversion and aftercare programmes for offenders using class A drugs: a systematic review and economic evaluation.

BACKGROUND: The societal costs of problematic class A drug use in England and Wales exceed £15B; drug-related crime accounts for almost 90% of costs. Diversion plus treatment and/or aftercare programmes may reduce drug-related crime and costs. OBJECTIVES: To assess the effectiveness and cost-effectiveness of diversion and aftercare for class A drug-using offenders, compared with no diversion. POPULATION: Adult class A drug-using offenders diverted to treatment or an aftercare programme for their drug use. INTERVENTIONS: Programmes to identify and divert problematic drug users to treatment (voluntary, court mandated or monitored services) at any point within the criminal justice system (CJS). Aftercare follows diversion and treatment, excluding care following prison or non-diversionary drug treatment. DATA SOURCES: Thirty-three electronic databases and government online resources were searched for studies published between January 1985 and January 2012, including MEDLINE, PsycINFO and ISI Web of Science. Bibliographies of identified studies were screened. The UK Drug Data Warehouse, the UK Drug Treatment Outcomes Research Study and published statistics and reports provided data for the economic evaluation. METHODS: Included studies evaluated diversion in adult class A drug-using offenders, in contact with the CJS. The main outcomes were drug use and offending behaviour, and these were pooled using meta-analysis. The economic review included full economic evaluations for adult opiate and/or crack, or powder, cocaine users. An economic decision analytic model, estimated incremental costs per unit of outcome gained by diversion and aftercare, over a 12-month time horizon. The perspectives included the CJS, NHS, social care providers and offenders. Probabilistic sensitivity analysis and one-way sensitivity analysis explored variance in parameter estimates, longer time horizons and structural uncertainty. RESULTS: Sixteen studies met the effectiveness review inclusion criteria, characterised by poor methodological quality, with modest sample sizes, high attrition rates, retrospective data collection, limited follow-up, no random allocation and publication bias. Most study samples comprised US methamphetamine users. Limited meta-analysis was possible, indicating a potential small impact of diversion interventions on reducing drug use [odds ratio (OR) 1.68, 95% confidence interval (CI) 1.12 to 2.53 for reduced primary drug use, and OR 2.60, 95% CI 1.70 to 3.98 for reduced use of other drugs]. The cost-effectiveness review did not identify any relevant studies. The economic evaluation indicated high uncertainty because of variance in data estimates and limitations in the model design. The primary analysis was unclear whether or not diversion was cost-effective. The sensitivity analyses indicated some scenarios where diversion may be cost-effective. LIMITATIONS: Nearly all participants (99.6%) in the effectiveness review were American (Californian) methamphetamine users, limiting transfer of conclusions to the UK. Data and methodological limitations mean it is unclear whether or not diversion is effective or cost-effective. CONCLUSIONS: High-quality evidence for the effectiveness and cost-effectiveness of diversion schemes is sparse and does not relate to the UK. Importantly this research identified a range of methodological limitations in existing evidence. These highlight the need for research to conceptualise, define and develop models of diversion programmes and identify a core outcome set. A programme of feasibility, pilot and definitive trials, combined with process evaluation and qualitative research is recommended to assess the effectiveness and cost-effectiveness of diversionary interventions in class A drug-using offenders.

Characteristics of drug users who do or do not have care of their children.

AIMS: To compare the relative frequency of eight indicators of problem drug use and potentially adverse social circumstances in drug-using parents and non-parents and to explore whether a profile based on these characteristics differs according to whether or not dependent children live with their drug-using parent. DESIGN: The study utilizes a 5 year national UK treatment monitoring system data set. SAMPLE: 61,425 users with, and 105,473 without dependent children accessing drug treatment services in England and Wales between January 1996 and December 2000. MEASUREMENTS: Information about parenthood and children's residence was routinely collected. Drug use and social circumstance indicators were daily heroin use, daily alcohol use, regular stimulant use, sharing of injecting equipment, living with another user, living alone, unstable accommodation, and criminal justice referral. FINDINGS: There were clear differences between drug-using parents according to where children live. Parents with children at home and non-parents showed fewer of the indicators than parents with children in care or elsewhere. Sixty-five percent of parents with none of the indicators lived with their children, compared with only 28% of those with three indicators and 9% of those with six or more indicators. Parents with children in care or living elsewhere showed the highest prevalence for each individual indicator. CONCLUSIONS: Drug-using parents demonstrate a range of potentially unfavourable drug use behaviours and social circumstances, but those whose children live with them use drugs less frequently and live in more favourable conditions than those whose children live elsewhere. Protective factors may operate in family situations, while severe drug use and adverse social circumstances may result in a breakdown of family structures.

Drug spend and acquisitive offending by substance misusers.

AIM: The need to generate income to fund drug misuse is assumed to be a driver of involvement in acquisitive crime. We examined the influence of drug misuse expenditure, and other factors, on acquisitive offending. METHODS: Clients (N=1380) seeking drug treatment within 94 of 149 Drug Action Teams (DATs) across England completed a comprehensive survey, incorporating validated scales and self-report measures, such as levels of drug and alcohol use and offending. RESULTS: Forty per cent (N=554) had committed acquisitive crime in the previous month. Regression analysis showed that acquisitive offending was associated with the presence of problematic use of crack cocaine, poly-drug use, sharing injecting equipment, unsafe sex, overdose risk, higher drug spend, unemployment, reduced mental wellbeing, and younger age. CONCLUSIONS: Rates of acquisitive crime among drug users are high. Drug using offenders can be distinguished from drug using non-offenders by problematic crack cocaine use, younger age, income-related factors, and indicators of a chaotic life style and complex needs. Behavioural and demographic factors were associated more strongly with acquisitive crime than drug use expenditure, suggesting that the need to finance drug use is not necessarily the main factor driving acquisitive offending by drug users.

Randomized controlled trial to assess the effectiveness of a primary health care liaison worker in promoting shared care for opiate users.

BACKGROUND: Recent national guidelines emphasize the requirement for all general practitioners to manage drug users within a shared care scheme and suggest that a primary health care liaison worker (PHCLW) may facilitate these arrangements. We undertook a group-randomized, randomized controlled trial to determine the effectiveness of a PHCLW in promoting shared care. METHODS: Primary health care teams in Stockport Health Authority, North West England, were randomly allocated to either an intervention arm, who were offered the services of a PHCLW, or to a control arm, who were offered standard support from the community drug team (CDT). The proportion of CDT clients with a history of regular opiate misuse who were in shared care 12 months after randomization was compared across study arms. RESULTS: Eighteen (24.0 per cent) of the 75 CDT clients in the intervention arm but none of the 80 CDT clients in the control arm were in shared care at 12 months (chi2 = 9.37, df = 1, p < 0.01; 95 per cent confidence interval 8.6-39.4 per cent). CONCLUSION: A PHCLW can significantly increase the number of CDT clients in shared care arrangements.
