RESUMO
AIMS: To compare the clinical effectiveness and cost-effectiveness of a stepped-care intervention versus a minimal intervention for the treatment of older hazardous alcohol users in primary care. METHOD: Multi-centre, pragmatic RCT, set in Primary Care in UK. Patients aged ≥ 55 years scoring ≥ 8 on the Alcohol Use Disorders Identification Test were allocated either to 5-min of brief advice or to 'Stepped Care': an initial 20-min of behavioural change counselling, with Step 2 being three sessions of Motivational Enhancement Therapy and Step 3 referral to local alcohol services (progression between each Step being determined by outcomes 1 month after each Step). Outcome measures included average drinks per day, AUDIT-C, alcohol-related problems using the Drinking Problems Index, health-related quality of life using the Short Form 12, costs measured from a NHS/Personal Social Care perspective and estimated health gains in quality adjusted life-years measured assessed EQ-5D. RESULTS: Both groups reduced alcohol consumption at 12 months but the difference between groups was small and not significant. No significant differences were observed between the groups on secondary outcomes. In economic terms stepped care was less costly and more effective than the minimal intervention. CONCLUSIONS: Stepped care does not confer an advantage over a minimal intervention in terms of reduction in alcohol use for older hazardous alcohol users in primary care. However, stepped care has a greater probability of being more cost-effective. TRIAL REGISTRATION: Current controlled trials ISRCTN52557360. SHORT SUMMARY: A stepped care approach was compared with brief intervention for older at-risk drinkers attending primary care. While consumption reduced in both groups over 12 months there was no significant difference between the groups. An economic analysis indicated the stepped care which had a greater probability of being more cost-effective than brief intervention.

AIMS: The aim of the study was to explore the relative efficiency and effectiveness of targeted versus universal screening for at-risk alcohol use in a primary care population in the UK. METHODS: The study was a randomized evaluation of screening approach (targeted versus universal) for consecutive attendees at primary care aged 18 years or more. Targeted screening involved screening any patient attending with one of the targeted presentations, conditions associated with excessive alcohol consumption: mental health, gastrointestinal, hypertension, minor injuries or a new patient registration. In the universal arm of the study all presentations in the recruitment period were included. Universal screening included all patients presenting to allocated practices. RESULTS: A total of 3562 potential participants were approached. The odds ratio of being screen positive was higher for the targeted group versus the universal group. Yet the vast majority of those screening positive in the universal group of the study would have been missed by a targeted approach. A combination of age and gender was a more efficient approach than targeting by clinical condition or context. CONCLUSIONS: While screening targeted by age and gender is more efficient than universal screening, targeting by clinical condition or presentation is not. Further universal screening is more effective in identifying the full range of patients who could benefit from brief alcohol interventions, and would therefore have greater public health impact. TRIAL REGISTRATION: Current Controlled Trials ISRCTN06145674.

BACKGROUND: The abbreviated Alcohol Use Disorder Identification Test for Consumption (AUDIT-C) is rapidly becoming the alcohol screening tool of choice for busy practitioners in clinical settings and by researchers keen to limit assessment burden and reactivity. Cut-off scores for detecting drinking above recommended limits vary by population, setting, country and potentially format. This validation study aimed to determine AUDIT-C thresholds that indicated risky drinking among a population of people seeking help over the Internet. METHOD: The data in this study were collected in the pilot phase of the Down Your Drink trial, which recruited people seeking help over the Internet and randomised them to a web-based intervention or an information-only website. Sensitivity, specificity, and positive and negative likelihood ratios were calculated for AUDIT-C scores, relative to weekly consumption that indicated drinking above limits and higher risk drinking. Receiver-operating characteristic (ROC) curves were created to assess the performance of different cut-off scores on the AUDIT-C for men and women. Past week alcohol consumption was used as the reference-standard and was collected via the TOT-AL, a validated online measure of past week drinking. RESULTS: AUDIT-C scores were obtained from 3720 adults (2053 female and 1667 male) searching the internet for help with drinking, mostly from the UK. The area under the ROC curve for risky drinking was 0.84 (95% CI 0.80, 0.87) (female) and 0.80 (95% CI 0.76, 0.84) (male). AUDIT-C cut-off scores for detecting risky drinking that maximise the sum of sensitivity and specificity were ≥8 for women and ≥8 for men; whereas those identifying the highest proportion of correctly classified individuals were ≥4 for women and ≥5 for men. AUDIT-C cut-off scores for detecting higher risk drinking were also calculated. CONCLUSIONS: AUDIT-C cut-off scores for identifying alcohol consumption above weekly limits in this largely UK based study population were substantially higher than those reported in other validation studies. Researchers and practitioners should select AUDIT-C cut-off scores according to the purpose of identifying risky drinkers and hence the relative importance of sensitivity and/or specificity.

AIMS: A pilot randomized controlled trial (RCT) to assess the feasibility and potential efficacy of assertive community treatment (ACT) in adults with alcohol dependence. METHODS: Single blind, individually randomized, pilot RCT of 12 months of ACT plus treatment as usual (TAU) versus TAU alone in adults (age 18+ years) with alcohol dependence and a history of previous unsuccessful alcohol treatment attending specialist community alcohol treatment services. ACT aimed to actively engage participants for 12 months with assertive, regular, minimum weekly contact. ACT was combined with TAU. TAU comprised access to the full range of services provided by the community teams. Primary outcome is mean drinks per drinking day and percent days abstinent at 12 months follow up. Analysis of covariance was conducted using 80% confidence intervals, appropriate in the context of a pilot trial. RESULTS: A total of 94 participants were randomized, 45 in ACT and 49 in TAU. Follow-up was achieved with 98 and 88%, respectively at 12 months. Those in ACT had better treatment engagement, and were more often seen in their homes or local community than TAU participants. At 12 months the ACT group had more problems related to drinking and lower quality of life than TAU but no differences in drinking measures. The ACT group had a higher percentage of days abstinent but lower quality of life at 6 months. The ACT group had less unplanned healthcare use than TAU. CONCLUSIONS: An trial of ACT was feasible to implement in an alcohol dependent treatment population. TRIAL REGISTRATION: ISRCTN22775534.

AIM: To examine the relative feasibility, acceptability, applicability, effectiveness and explore cost-effectiveness of a healthy living focused intervention (HL) compared to an alcohol-focused intervention (AF) for problem drinkers identified in hospital. METHODS: A pragmatic, randomised, controlled, open pilot trial. Feasibility and acceptability were measured by recruitment, attrition, follow-up rates and number of treatment sessions attended. Effectiveness was measured using the Alcohol Use Disorders Identification Test score at six months. Additional economic and secondary outcome measures were collected. RESULTS: Eighty-six participants were randomised and 72% (n=62) were retained in full participation. Forty-one participants attended at least one treatment session (48%). A greater proportion in the HL group attended all four treatment sessions (33% vs 19%). Follow-up rates were 29% at six months and 22% at twelve months. There was no evidence of a difference in AUDIT score between treatment groups at six months. Mean cost of health care and social services, policing and the criminal justice system use decreased while EQ-5D scores indicated minor improvement in both arms. However, this pilot trial was not powered to detect differences in either measure between groups. CONCLUSIONS: While no treatment effect was observed, this study demonstrated a potential to engage patients drinking at harmful or dependent levels in a healthy living intervention. However, recruitment proved challenging and follow-up rates were poor. Better ways need to be found to help these patients recognise the harms associated with their drinking and overcome the evident barriers to their engagement with specialist treatment.

BACKGROUND: This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness. OBJECTIVES: To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both. SEARCH METHODS: We searched 14 electronic bibliographic databases up to May 2014 and 5 Internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information. SELECTION CRITERIA: We included randomised controlled trials designed to reduce, eliminate, or prevent relapse of drug use and criminal activity, or both in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost-effectiveness of interventions. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: Eight trials with 2058 participants met the inclusion criteria. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most 'Risk of bias' items, we rated the majority of studies as unclear. Overall, we could not statistically combine the results due to the heterogenous nature of the different study interventions and comparison groups. A narrative summary of the findings identified that the interventions reported limited success with reducing self report drug use, but did have some impact on re-incarceration rates, but not re-arrest. In the single comparisons, we found moderate-quality evidence that therapeutic communities determine a reduction in re-incarceration but reported less success for outcomes of re-arrest, moderate quality of evidence and self report drug use. Three single studies evaluating case management via a mental health drug court (very low quality of evidence), motivational interviewing and cognitive skills (low and very low quality of evidence) and interpersonal psychotherapy (very low quality of evidence) did not report significant reductions in criminal activity and self report drug use respectively. Quality of evidence for these three types of interventions was low to very low. The trials reported some cost information, but it was not sufficient to be able to evaluate the cost-effectiveness of the interventions. AUTHORS' CONCLUSIONS: Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. Overall, the studies showed a high degree of variation, warranting a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. More evaluations are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

BACKGROUND: The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use or criminal activity, or both, for illicit drug-using offenders. OBJECTIVES: To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity or drug use, or both. SEARCH METHODS: We searched Fourteen electronic bibliographic databases up to May 2014 and five additional Web resources (between 2004 and November 2011). We contacted experts in the field for further information. SELECTION CRITERIA: We included randomised controlled trials assessing the efficacy of any pharmacological intervention a component of which is designed to reduce, eliminate or prevent relapse of drug use or criminal activity, or both, in drug-using offenders. We also report data on the cost and cost-effectiveness of interventions. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures as expected by Cochrane. MAIN RESULTS: Fourteen trials with 2647 participants met the inclusion criteria. The interventions included in this review report on agonistic pharmacological interventions (buprenorphine, methadone and naltrexone) compared to no intervention, other non-pharmacological treatments (e.g. counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). Studies could not be combined all together because the comparisons were too different. Only subgroup analysis for type of pharmacological treatment were done. When compared to non-pharmacological, we found low quality evidence that agonist treatments are not effective in reducing drug use or criminal activity, objective results (biological) (two studies, 237 participants (RR 0.72 (95% CI 0.51 to 1.00); subjective (self-report), (three studies, 317 participants (RR 0.61 95% CI 0.31 to 1.18); self-report drug use (three studies, 510 participants (SMD: -0.62 (95% CI -0.85 to -0.39). We found low quality of evidence that antagonist treatment was not effective in reducing drug use (one study, 63 participants (RR 0.69, 95% CI 0.28 to 1.70) but we found moderate quality of evidence that they significantly reduced criminal activity (two studies, 114 participants, (RR 0.40, 95% CI 0.21 to 0.74).Findings on the effects of individual pharmacological interventions on drug use and criminal activity showed mixed results. In the comparison of methadone to buprenorphine, diamorphine and naltrexone, no significant differences were displayed for either treatment for self report dichotomous drug use (two studies, 370 participants (RR 1.04, 95% CI 0.69 to 1.55), continuous measures of drug use (one study, 81 participants, (mean difference (MD) 0.70, 95% CI -5.33 to 6.73); or criminal activity (one study, 116 participants, (RR 1.25, 95% CI 0.83 to 1.88) between methadone and buprenorphine. Similar results were found for comparisons with diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants, (RR 1.25, 95% CI 1.03 to 1.51) or naltrexone for dichotomous measures of reincarceration (one study, 44 participants, (RR 1.10, 95% CI 0.37 to 3.26), and continuous outcome measure of crime, (MD -0.50, 95% CI -8.04 to 7.04) or self report drug use (MD 4.60, 95% CI -3.54 to 12.74). AUTHORS' CONCLUSIONS: When compared to non-pharmacological treatment, agonist treatments did not seem effective in reducing drug use or criminal activity. Antagonist treatments were not effective in reducing drug use but significantly reduced criminal activity. When comparing the drugs to one another we found no significant differences between the drug comparisons (methadone versus buprenorphine, diamorphine and naltrexone) on any of the outcome measures. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias.

INTRODUCTION AND AIMS: Delivering brief interventions for hazardous and harmful drinking on the Internet may broaden the availability of services and overcome some barriers to accessing help in person. The Down Your Drink (DYD) website, an extended brief intervention, attracted a large number of people looking to reduce their drinking. The aim was to explore the experiences of this e-help seeking population. METHOD: Semi-structured interviews were conducted with participants in the DYD trial - an online trial of the effectiveness of DYD compared with an information-only website. Interviewees were asked how they came across the DYD website. Interviews were recorded and transcribed verbatim. Data were analysed by a multidisciplinary team using detailed thematic analysis. RESULTS: Eighteen participants were interviewed. Most interviewees perceived their drinking to be a problem, which led them to search the Internet and register for the DYD trial in order to gain access to an intervention to help them reduce their drinking. The type of help required varied from information on the harms of drinking to help with a recognized problem. The privacy of the Internet was perceived as important when searching for help with drinking, as this avoids the stigma and embarrassment associated with help seeking in person. Almost all interviewees perceived a lack of services both online and offline for people wanting to moderate their drinking. CONCLUSION: There is a perceived gap in services for hazardous and harmful drinkers wanting to reduce their drinking which could be addressed using online interventions.

AIM: To explore the feasibility and cost effectiveness of screening and delivery of a brief intervention for hazardous drinking employees. METHODS: A pilot randomised controlled trial of a brief intervention delivered by an Occupational Health nurse versus no delivery of brief intervention (control group) conducted in a Local Authority Council (LCA) in the United Kingdom. Changes in quality of life and economic indicators were measured by the EQ-5D. RESULTS: 627 employees were screened of whom 163 (26.01%) fulfilled the inclusion criteria with a total of 57 (35%) agreeing to participate. No significant differences were found between the groups for baseline demographics or levels/patterns of alcohol consumption. A statistically significant effect was found in the mean AUDIT scores over time (F=8.96, p=0.004) but not for group (F=0.017, p=0.896), and no significant interaction was found (F=0.148, p=0.702). The cost of each intervention was calculated at £12.48, the difference in service costs was calculated at £344.50 per person; that is there was a net saving of health and other care costs in the intervention group compared to the control group. The QALYs fell in both intervention and control groups, the difference -0.002-(-0.010) yields a net advantage of the intervention of 0.008 QALYs. CONCLUSION: The main results from this pilot study suggest that alcohol brief interventions delivered in the workplace may offer the potential to reduce alcohol-related harm and save public sector resources. A fully powered multi-centre trial is warranted to contribute to the current evidence base and explore further the potential of alcohol brief interventions in the workplace. In a full trial the recruitment method may need to be re-considered.

AIM: To evaluate the effectiveness of different brief intervention strategies at reducing hazardous or harmful drinking in the probation setting. Offender managers were randomized to three interventions, each of which built on the previous one: feedback on screening outcome and a client information leaflet control group, 5 min of structured brief advice and 20 min of brief lifestyle counselling. METHODS: A pragmatic multicentre factorial cluster randomized controlled trial. The primary outcome was self-reported hazardous or harmful drinking status measured by Alcohol Use Disorders Identification Test (AUDIT) at 6 months (negative status was a score of <8). Secondary outcomes were AUDIT status at 12 months, experience of alcohol-related problems, health utility, service utilization, readiness to change and reduction in conviction rates. RESULTS: Follow-up rates were 68% at 6 months and 60% at 12 months. At both time points, there was no significant advantage of more intensive interventions compared with the control group in terms of AUDIT status. Those in the brief advice and brief lifestyle counselling intervention groups were statistically significantly less likely to reoffend (36 and 38%, respectively) than those in the client information leaflet group (50%) in the year following intervention. CONCLUSION: Brief advice or brief lifestyle counselling provided no additional benefit in reducing hazardous or harmful drinking compared with feedback on screening outcome and a client information leaflet. The impact of more intensive brief intervention on reoffending warrants further research.

BACKGROUND: Alcohol misuse is common in people attending emergency departments (EDs) and there is some evidence of efficacy of alcohol screening and brief interventions (SBI). This study investigated the effectiveness of SBI approaches of different intensities delivered by ED staff in nine typical EDs in England: the SIPS ED trial. METHODS AND FINDINGS: Pragmatic multicentre cluster randomized controlled trial of SBI for hazardous and harmful drinkers presenting to ED. Nine EDs were randomized to three conditions: a patient information leaflet (PIL), 5 minutes of brief advice (BA), and referral to an alcohol health worker who provided 20 minutes of brief lifestyle counseling (BLC). The primary outcome measure was the Alcohol Use Disorders Identification Test (AUDIT) status at 6 months. Of 5899 patients aged 18 or more presenting to EDs, 3737 (63·3%) were eligible to participate and 1497 (40·1%) screened positive for hazardous or harmful drinking, of whom 1204 (80·4%) gave consent to participate in the trial. Follow up rates were 72% (nâ=â863) at six, and 67% (nâ=â810) at 12 months. There was no evidence of any differences between intervention conditions for AUDIT status or any other outcome measures at months 6 or 12 in an intention to treat analysis. At month 6, compared to the PIL group, the odds ratio of being AUDIT negative for brief advice was 1·103 (95% CI 0·328 to 3·715). The odds ratio comparing BLC to PIL was 1·247 (95% CI 0·315 to 4·939). A per protocol analysis confirmed these findings. CONCLUSIONS: SBI is difficult to implement in typical EDs. The results do not support widespread implementation of alcohol SBI in ED beyond screening followed by simple clinical feedback and alcohol information, which is likely to be easier and less expensive to implement than more complex interventions. TRIAL REGISTRATION: Current Controlled Trials ISRCTN 93681536.

BACKGROUND: This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders. OBJECTIVES: To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity or drug use, or both. SEARCH METHODS: We searched 14 electronic bibliographic databases (between 2004 and 21st March 2013) and five additional web resources (between 2004 and November 2011). We contacted experts in the field for further information. SELECTION CRITERIA: We include randomised controlled trials designed to reduce, eliminate or prevent relapse in female drug-using offenders. We also report data on the cost and cost effectiveness of interventions. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by the Cochrane Collaboration. MAIN RESULTS: We identified 76 trials across the four reviews. Following a process of prescreening, we judged that 11 trials met the inclusion criteria of the specified review; four of the 11 trials are awaiting classification in the review. The remaining seven trials cover 1236 participants. The interventions included in this review report on therapeutic communities (TCs), gender-responsive treatment (GRT), use of case management and cognitive skills, and a pharmacological intervention using buprenorphine. Trial quality and risks of bias varied across each study. The majority of studies were rated as being at 'unclear' risk of bias due to a lack of descriptive information. Overall the interventions showed statistically significant reductions in self-reported drug use, (four studies, 734 participants, risk ratio (RR) 0.68; 95% confidence interval (CI) 0.58 to 0.80) and re-incarceration, (four studies, 745 participants, RR 0.55; 95% CI 0.41 to 0.72). We found a statistically non-significant result for re-arrest (three studies, 803 participants, RR 0.80; 95% CI 0.53 to 1.19). Individual treatment results found that TCs and a GRT programme showed a statistically significant reduction in re-incarceration (one study, 509 participants, RR 0.42; 95% CI 0.29 to 0.60) but not for re-arrest, (one study, 314 participants, RR 0.73; 95% CI 0.52 to 1.03) and self-reported drug use (two studies, 825 participants, RR 0.47; 95% CI 0.14 to 1.53). Case management and cognitive skills programmes did not significantly reduce re-arrests, (one study, 183 participants RR 1.12; 95% CI 0.89 to 1.41) or self-reported drug use, (one study, 77 participants, RR 0.65; 95% CI 0.20 to 2.12), but did show a statistically significant reduction in re-incarceration, (three studies, 236 participants, RR 0.63; 95% CI 0.49 to 0.81). Buprenorphine did not significantly reduce self-reported drug use (RR 0.58; 95% CI 0.25 to 1.35), but this result came from a single study with only 36 participants. Due to the small number of studies we were unable to analyse the impact of treatment setting on outcome. No cost and cost effectiveness evidence was reported in the studies. AUTHORS' CONCLUSIONS: The seven trials show some positive results for the use of treatments to reduce self-reported drug use and subsequent re-incarceration. However, the studies overall showed a high degree of statistical variation, requiring a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.

BACKGROUND: This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness. OBJECTIVES: To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both. SEARCH METHODS: We searched 14 electronic bibliographic databases (searched between 2004 and 21 March 2013) and five internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information. SELECTION CRITERIA: We included randomised controlled trials designed to reduce, eliminate or prevent relapse in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost effectiveness of interventions. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We identified 76 trials across the four reviews. Following a process of pre-screening, we judged eight trials to meet the inclusion criteria for this specific review (three of the five trials are awaiting classification). The five included 1502 participants. The interventions reported on case management via a mental health drugs court, a therapeutic community, and an evaluation of a motivational interviewing technique and cognitive skills in comparison to relaxation training. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most risk of bias items, we rated the majority of studies as unclear. Overall, the combined interventions did not show a statistically significant reduction in self reported drug use (2 studies, 715 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.44 to 1.55). A statistically significantly reduction was shown for re-incarceration (4 studies, 627 participants; RR 0.40, 95% CI 0.24 to 0.67 and mean difference (MD) 28.72, 95% CI 5.89 to 51.54) but not re-arrest (2 studies, 518 participants; RR 1.00, 95% CI 0.90 to 1.12). A specific subgroup analysis combining studies using therapeutic community interventions showed a statistically significant reduction in re-incarceration (2 studies, 266 participants; RR 0.29, 95% CI 0.16 to 0.54) but not re-arrest (1 study, 428 participants; RR 0.90, 95% CI 0.61 to 1.33). Case management via a mental health court and motivational interviewing with cognitive skills did not show a statistically significant reduction in criminal activity (1 study, 235 participants; RR 1.05, 95% CI 0.90 to 1.22) or self reported drug misuse (1 study, 162 participants; MD -7.42, 95% CI -20.12 to 5.28). Due to the small number of studies, we were unable to analyse the impact of setting on outcome. Some cost information was provided in the trials but not sufficient to be able to evaluate the cost effectiveness of the interventions. AUTHORS' CONCLUSIONS: This review highlights the paucity of evidence for drug misusing offenders with co-occurring mental health problems. Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. The studies overall, showed a high degree of statistical variation demonstrating a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes.

PURPOSE: To investigate the ability of the EQ-5D to discriminate between levels of alcohol risk in a large sample of hazardous and harmful drinkers, and to explore the relationship between transitions between alcohol risk levels and changes in EQ-5D up to 12 months. METHODS: This is a web-based randomised controlled trial evaluating a novel intervention for hazardous and harmful alcohol consumption. EQ-5D scores were compared among groups of drinkers at baseline (low/medium/high risk according to self-reported past week alcohol consumption), and changes in EQ-5D scores were estimated as a function of changes in alcohol consumption level. RESULTS: Baseline EQ-5D scores were dominated by problems with anxiety/depression, which increased with alcohol risk level, whilst high-risk drinkers also experienced more problems with physical HRQoL dimensions. However, the tool demonstrated a considerable ceiling effect. At follow-up, despite considerable reductions in alcohol consumption across the sample, significant changes in aggregated EQ-5D index scores were only observed for high-risk drinkers at baseline who reduced their drinking, with small improvements (0.04-0.06) compared to those who did not reduce. CONCLUSIONS: Our results suggest that the three-option EQ-5D may not be an optimal primary end point for measuring clinical and cost-effectiveness in randomised controlled trials of interventions among hazardous and harmful alcohol users, although further testing of the sensitivity of the tool in these populations is needed.

INTRODUCTION: Smoking remains a significant public health problem and is a leading cause of preventable morbidity and mortality around the world. By combining the behavioral intervention principles used in specialist services with the high reach rates of public health interventions, personal tailored self-help cessation intervention provides a potential economical method for improving reach and effectiveness. METHODS: Cost-effectiveness analysis is performed alongside a randomized controlled trial to compare the computer-tailored self-help intervention with a generic self-help intervention in smoking cessation. A Markov model was developed to extrapolate lifetime cost-effectiveness by combining trial data with estimates from the literature. FINDINGS: In the short term, smokers in the intervention group gained 0.0006 (95% CI = -0.0024 to 0.0036) quality-adjusted life years (QALYs) more than those in the control group at an increased cost of about £9 per person (95% CI = £5-£12). This yielded an incremental cost-effectiveness ratio (ICER) of £14,432/QALY. Precision of the ICER estimates was assessed by 5,000 bootstrapping replications. The probability that the intervention was cost effective was 54% (58%) at a cost-effectiveness threshold of £20,000(£30,000) per QALY. The Markov model showed that simulating lifetime outcomes improved the cost-effectiveness ratio (£9,700/QALY) in favor of the tailored intervention. The intervention would have a 55%-57% chance of being more cost effective than nontailored intervention at the willingness-to-pay threshold of £20,000-30,000/QALY. CONCLUSIONS: The computer-tailored intervention appears slightly more likely to be cost effective than the generic self-help intervention in smoking cessation, in both the short term and the long term, but caution is required given the considerable uncertainty surrounding the estimates.

BACKGROUND: The UK Misuse of Drugs Act (1971) divided controlled drugs into three groups A, B and C, with descending criminal sanctions attached to each class. Cannabis was originally assigned by the Act to Group B but in 2004, it was transferred to the lowest risk group, Group C. Then in 2009, on the basis of increasing concerns about a link between high strength cannabis and schizophrenia, it was moved back to Group B. The aim of this study is to test the assumption that changes in classification lead to changes in levels of psychosis. In particular, it explores whether the two changes in 2004 and 2009 were associated with changes in the numbers of people admitted for cannabis psychosis. METHOD: An interrupted time series was used to investigate the relationship between the two changes in cannabis classification and their impact on hospital admissions for cannabis psychosis. Reflecting the two policy changes, two interruptions to the time series were made. Hospital Episode Statistics admissions data was analysed covering the period 1999 through to 2010. RESULTS: There was a significantly increasing trend in cannabis psychosis admissions from 1999 to 2004. However, following the reclassification of cannabis from B to C in 2004, there was a significant change in the trend such that cannabis psychosis admissions declined to 2009. Following the second reclassification of cannabis back to class B in 2009, there was a significant change to increasing admissions. CONCLUSION: This study shows a statistical association between the reclassification of cannabis and hospital admissions for cannabis psychosis in the opposite direction to that predicted by the presumed relationship between the two. However, the reasons for this statistical association are unclear. It is unlikely to be due to changes in cannabis use over this period. Other possible explanations include changes in policing and systemic changes in mental health services unrelated to classification decisions.

BACKGROUND: The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use and/or criminal activity for illicit drug-using offenders. OBJECTIVES: To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity and/or drug use. SEARCH METHODS: Fourteen electronic bibliographic databases (searched between 2004 and 21 March 2013) and five additional Web resources (searched between 2004 and 11 November 2011) were searched. Experts in the field were contacted for further information. SELECTION CRITERIA: Randomised controlled trials assessing the efficacy of any pharmacological interventions for reducing, eliminating or preventing relapse in drug-using offenders were included. Data on the cost and cost-effectiveness of interventions were reported. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures as expected by The Cochrane Collaboration. MAIN RESULTS: A total of 76 trials across the four reviews were identified. After a process of prescreening had been completed, 17 trials were judged to meet the inclusion criteria for this specific review (six of the 17 trials are awaiting classification for the review). The remaining 11 trials contained a total of 2,678 participants. Nine of the eleven studies used samples with a majority of men. The interventions (buprenorphine, methadone and naltrexone) were compared to non pharmacological treatments (e.g., counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). When combined, the results suggest that pharmacological interventions do significantly reduce subsequent drug use using biological measures, (three studies, 300 participants, RR 0.71 (95% CI 0.52 to 0.97)), self report dichotomous data (three studies, 317 participants, RR 0.42, (95% CI 0.22 to 0.81)) and continuous measures (one study, MD -59.66 (95% CI -120.60 to 1.28)) . In the subgroups analysis for community setting, (two studies, 99 participants: RR 0.62 (95% CI 0.35 to 1.09)) and for secure establishment setting, (one study, 201 participants: RR 0.76 (95% CI 0.52 to 1.10)), the results are no longer statistically significant. Criminal activity was significantly reduced favouring the dichotomous measures of re arrest, (one study, 62 participants, RR 0.60 (95% CI 0.32 to 1.14)), re-incarceration, (three studies, 142 participants, RR 0.33 (95% CI 0.19 to 0.56)) and continuous measures (one study, 51 participants, MD -74.21 (95% CI -133.53 to -14.89)). Findings on the effects of individual pharmacological interventions on drug use and criminal activity show mixed results. Buprenorphine in comparison to a non pharmacological treatment seemed to favour buprenorphine but not significantly with self report drug use, (one study, 36 participants, RR 0.58 (95% CI 0.25 to 1.35)). Methadone and cognitive behavioural skills in comparison to standard psychiatric services, did show a significant reduction for self report dichotomous drug use (one study, 253 participants, RR 0.43 (95% CI 0.33 to 0.56)) but not for self report continuous data (one study 51 participants) MD -0.52 (95% CI -1.09 to 0.05)), or re incarceration RR 1.23 (95% CI 0.53 to 2.87)). Naltrexone was favoured significantly over routine parole and probation for re incarceration (two studies 114 participants, RR 0.36 (95% CI 0.19 to 0.69)) but no data was available on drug use. Finally, we compared each pharmacological treatment to another. In each case we compared methadone to: buprenorphine, diamorphine and naltrexone. No significant differences were displayed for either treatment for self report dichotomous drug use (one study, 193 participants RR 1.23 (95% CI 0.86 to 1.76)), continuous measures of drug use MD 0.70 (95% CI -5.33 to 6.73) or criminal activity RR 1.25 (95% CI 0.83 to 1.88)) between methadone and buprenorphine. Similiar results were found for comparisons with Diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants RR 1.25 (95% CI 1.03-1.51)) or Naltrexone for dichotomous measures of re incarceration (one study, 44 participants, RR 1.10 (95% CI 0.37 to 3.26)), and continuous outcome measure of crime MD -0.50 (95% CI -8.04 to 7.04)) or self report drug use MD 4.60 (95% CI -3.54 to 12.74)). AUTHORS' CONCLUSIONS: Pharmacological interventions for drug-using offenders do appear to reduce overall subsequent drug use and criminal activity (but to a lesser extent). No statistically significant differences were displayed by treatment setting. Individual differences are displayed between the three pharmacological interventions (buprenorphine, methadone and naltrexone) when compared to a non pharmacological intervention, but not when compared to each other. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias because trial information was inadequately described.

BACKGROUND: Attrition is a noted feature of eHealth interventions and trials. In 2005, Eysenbach published a landmark paper calling for a "science of attrition," suggesting that the 2 forms of attrition--nonusage attrition (low adherence to the intervention) and dropout attrition (poor retention to follow-up)--may be related and that this potential relationship deserved further study. OBJECTIVE: The aim of this paper was to use data from an online alcohol trial to explore Eysenbach's hypothesis, and to answer 3 research questions: (1) Are adherence and retention related? If so, how, and under which circumstances? (2) Do adherence and retention have similar predictors? Can these predictors adequately explain any relationship between adherence and retention or are there additional, unmeasured predictors impacting on the relationship? (3) If there are additional unmeasured predictors impacting on the relationship, are there data to support Eysenbach's hypothesis that these are related to overall levels of interest? METHODS: Secondary analysis of data from an online trial of an online intervention to reduce alcohol consumption among heavy drinkers. The 2 outcomes were adherence to the intervention measured by number of log-ins, and retention to the trial measured by provision of follow-up data at 3 months (the primary outcome point). Dependent variables were demographic and alcohol-related data collected at baseline. Predictors of adherence and retention were modeled using logistic regression models. RESULTS: Data were available on 7932 participants. Adherence and retention were related in a complex fashion. Participants in the intervention group were more likely than those in the control group to log in more than once (42% vs 28%, P<.001) and less likely than those in the control group to respond at 3 months (40% vs 49%, P<.001). Within each randomized group, participants who logged in more frequently were more likely to respond than those who logged in less frequently. Response rates in the intervention group for those who logged in once, twice, or ≥3 times were 34%, 46%, and 51%, respectively (P<.001); response rates in the control group for those who logged in once, twice, or ≥3 times were 44%, 60%, and 67%, respectively (P<.001). Relationships between baseline characteristics and adherence and retention were also complex. Where demographic characteristics predicted adherence, they tended also to predict retention. However, characteristics related to alcohol consumption and intention or confidence in reducing alcohol consumption tended to have opposite effects on adherence and retention, with factors that predicted improved adherence tending to predict reduced retention. The complexity of these relationships suggested the existence of an unmeasured confounder. CONCLUSIONS: In this dataset, adherence and retention were related in a complex fashion. We propose a possible explanatory model for these data.
