Project description:To undertake the first randomized controlled trial to evaluate the effectiveness of a brief intervention delivered by community pharmacists to reduce hazardous or harmful drinking.This parallel group randomized trial allocated participants individually to brief alcohol intervention (n?=?205) or a leaflet-only control condition (n?=?202), with follow-up study after 3 months.Sixteen community pharmacies in one London Borough, UK.A total of 407 pharmacy customers (aged 18?years or over) with Alcohol Use Disorder Identification Test (AUDIT) scores 8-19, inclusive.A brief motivational discussion of approximately 10 minutes' duration, for which 17 pharmacists received a half-day of training.Hazardous or harmful drinking was assessed using the AUDIT administered by telephone by a researcher blind to allocation status. The two primary outcomes were: (1) change in AUDIT total scores and (2) the proportions no longer hazardous or harmful drinkers (scoring <?8) at 3?months. The four secondary outcomes were: the three subscale scores of the AUDIT (for consumption, problems and dependence) and health status according to the EQ-5D (a standardized instrument for use as a measure of health outcome).At 3 months 326 (80% overall; 82% intervention, 78% control) participants were followed-up. The difference in reduction in total AUDIT score (intervention minus control) was -0.57, 95% confidence interval (CI)?=?-1.59 to 0.45, P?=?0.28. The odds ratio for AUDIT ??8 (control as reference) was 0.87, 95% CI?=?0.50 to 1.51, P?=?0.61). For two of the four secondary outcomes (dependence score: -0.46, 95% CI?=?-0.82 to -0.09, P?=?0.014; health status score: -0.09, 95% CI?=?-0.16 to -0.02, P?=?0.013) the control group did better, and in the other two there were no differences (consumption score: -0.05, 95% CI?=?-0.54 to 0.44, P?=?0.85; non-dependence problems score: -0.13, 95% CI?=?-0.66 to 0.41). Sensitivity analyses did not change these findings.A brief intervention delivered by community pharmacists appears to have had no effect in reducing hazardous or harmful alcohol consumption.

Project description:INTRODUCTION: Excessive alcohol consumption increases the risk of many diseases and injuries, and the Global Burden of Disease 2010 study estimated that 6% of the burden of disease in Denmark is due to alcohol consumption. Alcohol consumption thus places a considerable economic burden on society. METHODS: We analysed the cost-effectiveness of six interventions aimed at preventing alcohol abuse in the adult Danish population: 30% increased taxation, increased minimum legal drinking age, advertisement bans, limited hours of retail sales, and brief and longer individual interventions. Potential health effects were evaluated as changes in incidence, prevalence and mortality of alcohol-related diseases and injuries. Net costs were calculated as the sum of intervention costs and cost offsets related to treatment of alcohol-related outcomes, based on health care costs from Danish national registers. Cost-effectiveness was evaluated by calculating incremental cost-effectiveness ratios (ICERs) for each intervention. We also created an intervention pathway to determine the optimal sequence of interventions and their combined effects. RESULTS: Three of the analysed interventions (advertising bans, limited hours of retail sales and taxation) were cost-saving, and the remaining three interventions were all cost-effective. Net costs varied from € -17 million per year for advertisement ban to € 8 million for longer individual intervention. Effectiveness varied from 115 disability-adjusted life years (DALY) per year for minimum legal drinking age to 2,900 DALY for advertisement ban. The total annual effect if all interventions were implemented would be 7,300 DALY, with a net cost of € -30 million. CONCLUSION: Our results show that interventions targeting the whole population were more effective than individual-focused interventions. A ban on alcohol advertising, limited hours of retail sale and increased taxation had the highest probability of being cost-saving and should thus be first priority for implementation.

Project description:BackgroundRates of perinatal depression (antenatal and postnatal depression) in South Asia are among the highest in the world. The delivery of effective psychological treatments for perinatal depression through existing health systems is a challenge due to a lack of human resources. This paper reports on a trial protocol that aims to evaluate the effectiveness and cost-effectiveness of the Thinking Healthy Programme delivered by peers (Thinking Healthy Programme Peer-delivered; THPP), for women with moderate to severe perinatal depression in rural and urban settings in Pakistan and India.Methods/designTHPP is evaluated with two randomised controlled trials: a cluster trial in Rawalpindi, Pakistan, and an individually randomised trial in Goa, India. Trial participants are pregnant women who are registered with the lady health workers in the study area in Pakistan and pregnant women attending outpatient antenatal clinics in India. They will be screened using the patient health questionnaire-9 (PHQ-9) for depression symptoms and will be eligible if their PHQ-9 is equal to or greater than 10 (PHQ-9 ≥ 10). The sample size will be 560 and 280 women in Pakistan and India, respectively. Women in the intervention arm (THPP) will be offered ten individual and four group sessions (Pakistan) or 6-14 individual sessions (India) delivered by a peer (defined as a mother from the same community who is trained and supervised in delivering the intervention). Women in the control arm (enhanced usual care) will receive health care as usual, enhanced by providing the gynaecologist or primary-health facilities with adapted WHO mhGAP guidelines for depression treatment, and providing the woman with her diagnosis and information on how to seek help for herself. The primary outcomes are remission and severity of depression symptoms at the 6-month postnatal follow-up. Secondary outcomes include remission and severity of depression symptoms at the 3-month postnatal follow-up, functional disability, perceived social support, breastfeeding rates, infant height and weight, and costs of health care at the 3- and 6-month postnatal follow-ups. The primary analysis will be intention-to-treat.DiscussionThe trials have the potential to strengthen the evidence on the effectiveness and cost-effectiveness of an evidence-based psychological treatment recommended by the World Health Organisation and delivered by peers for perinatal depression. The trials have the unique opportunity to overcome the shortage of human resources in global mental health and may advance our understanding about the use of peers who work in partnership with the existing health systems in low-resource settings.Trial registrationPakistan Trial: ClinicalTrials.gov Identifier: NCT02111915 (9 April 2014) India Trial: ClinicalTrials.gov Identifier: NCT02104232 (1 April 2014).

Project description:Cocaine and alcohol are two substances of abuse that prominently affect the central nervous system (CNS). Repeated exposure to cocaine and alcohol leads to longstanding changes in gene expression, and subsequent functional CNS plasticity, throughout multiple brain regions. Epigenetic modifications of histones are one proposed mechanism guiding these enduring changes to the transcriptome. Characterizing the large number of available biological relationships as network models can reveal unexpected biochemical relationships. Clustering analysis of variation from whole-genome sequencing of gene expression (RNA-Seq) and histone H3 lysine 4 trimethylation (H3K4me3) events (ChIP-Seq) revealed the underlying structure of the transcriptional and epigenomic landscape within hippocampal postmortem brain tissue of drug abusers and control cases. Distinct sets of interrelated networks for cocaine and alcohol abuse were determined for each abusive substance. The network approach identified subsets of functionally related genes that are regulated in agreement with H3K4me3 changes, suggesting cause and effect relationships between this epigenetic mark and gene expression. Gene expression networks consisted of recognized substrates for addiction, such as the dopamine- and cAMP-regulated neuronal phosphoprotein PPP1R1B/DARPP-32 and the vesicular glutamate transporter SLC17A7/VGLUT1 as well as potentially novel molecular targets for substance abuse. Through a systems biology based approach our results illustrate the utility of integrating epigenetic and transcript expression to establish relevant biological networks in the human brain for addiction. Future work with laboratory models may clarify the functional relevance of these gene networks for cocaine and alcohol, and provide a framework for the development of medications for the treatment of addiction.

Project description:IntroductionCrisis resolution teams (CRTs) provide assessment and intensive home treatment in a crisis, aiming to offer an alternative for people who would otherwise require a psychiatric inpatient admission. They are available in most areas in England. Despite some evidence for their clinical and cost-effectiveness, recurrent concerns are expressed regarding discontinuity with other services and lack of focus on preventing future relapse and readmission to acute care. Currently evidence on how to prevent readmissions to acute care is limited. Self-management interventions, involving supporting service users in recognising and managing signs of their own illness and in actively planning their recovery, have some supporting evidence, but have not been tested as a means of preventing readmission to acute care in people leaving community crisis care. We thus proposed the current study to test the effectiveness of such an intervention. We selected peer support workers as the preferred staff to deliver such an intervention, as they are well-placed to model and encourage active and autonomous recovery from mental health problems.Methods and analysisThe CORE (CRT Optimisation and Relapse Prevention) self-management trial compares the effectiveness of a peer-provided self-management intervention for people leaving CRT care, with treatment as usual supplemented by a booklet on self-management. The planned sample is 440 participants, including 40 participants in an internal pilot. The primary outcome measure is whether participants are readmitted to acute care over 1 year of follow-up following entry to the trial. Secondary outcomes include self-rated recovery at 4 and at 18 months following trial entry, measured using the Questionnaire on the Process of Recovery. Analysis will follow an intention to treatment principle. Random effects logistic regression modelling with adjustment for clustering by peer support worker will be used to test the primary hypothesis.Ethics and disseminationThe CORE self-management trial was approved by the London Camden and Islington Research Ethics Committee (REC ref: 12/LO/0988). A Trial Steering Committee and Data Monitoring Committee oversee the progress of the study. We will report on the results of the clinical trial, as well as on the characteristics of the participants and their associations with relapse.Trial registration numberISRCTN 01027104;pre-results stage.

Project description:AIMS:To examine the feasibility, acceptability and preliminary cost-effectiveness of a lay counsellor delivered psychological treatment for men with alcohol dependence in primary care. DESIGN:Single-blind individually randomized trial comparing counselling for alcohol problems (CAP) plus enhanced usual care (EUC) versus EUC only. SETTING:Ten primary health centres in Goa, India. PARTICIPANTS:Men (n = 135) scoring ≥ 20 on the Alcohol Use Disorder Identification Test (AUDIT). Sixty-six participants were randomized to EUC and 69 to CAP + EUC. INTERVENTIONS:CAP, a lay counsellor-delivered psychological treatment for harmful drinking, with referral to de-addiction centre for medically assisted detoxification. EUC comprised consultation with physician, providing screening results and referral to a de-addiction centre. MEASUREMENTS:Baseline socio-demographic data, readiness to change and perceived usefulness of counselling. Acceptability and feasibility process indicators such as data on screening and therapy. Outcomes were measured at 3 and 12 months post-randomization and included remission, mean daily alcohol consumed, percentage of days abstinent (PDA), percentage of days of heavy drinking (PDHD), recovery, uptake of detoxification services, impacts of alcohol dependence, resource use and costs. FINDINGS:Participants in the CAP + EUC arm had more numerically but not statistically significantly favourable outcomes compared with those in the EUC arm for (a) remission at 3 months [adjusted odds ratio (aOR) = 1.95, 95% confidence interval (CI) = 0.74-5.15] and 12 months (aOR = 1.90, 95% CI = 0.72-5.00), (b) proportion of non-drinkers at 3 months (aOR = 1.26; 95% CI = 0.58-2.75) and 12 months (aOR = 1.25; 95% CI = 0.58-2.64) and (c) ethanol consumption among drinkers at 3 months (count ratio = 0.91; 95% CI = 0.58-1.45) and 12 months (count ratio = 1.06; 95% CI = 0.73-1.54). There was no statistically significant evidence of a difference in the occurrence of serious adverse events between the two arms. From a societal perspective, there was a 53% chance of CAP + EUC being cost-effective in achieving remission at 12 months at the willingness-to-pay threshold of $415. CONCLUSIONS:Lay counsellor-delivered psychological treatment for men with alcohol dependence (AD) in primary care may be effective in managing AD in low- and middle-income countries. A definitive trial of the intervention is warranted.

Project description:BackgroundDevelopment of new peer or lay health-related lifestyle advisor (HRLA) roles is one response to the need to enhance public engagement in, and improve cost-effectiveness of, health improvement interventions. This article synthesises evidence on the cost-effectiveness of HRLA interventions aimed at adults in developed countries, derived from the first systematic review of the effectiveness, cost-effectiveness, equity and acceptability of different types of HRLA role.MethodsThe best available evidence on the cost-effectiveness of HRLA interventions was obtained using systematic searches of 20 electronic databases and key journals, as well as searches of the grey literature and the internet. Interventions were classified according to the primary health behaviour targeted and intervention costs were estimated where necessary. Lifetime health gains were estimated (in quality-adjusted life years, where possible), based on evidence of effectiveness of HRLAs in combination with published estimates of the lifetime health gains resulting from lifestyle changes, and assumptions over relapse. Incremental cost-effectiveness ratios are reported.ResultsEvidence of the cost-effectiveness of HRLAs was identified from 24 trials included in the systematic review. The interventions were grouped into eight areas. We found little evidence of effectiveness of HRLAs for promotion of exercise/improved diets. Where HRLAs were effective cost-effectiveness varied considerably: Incremental Cost effectiveness Ratios were estimated at £6,000 for smoking cessation; £14,000 for a telephone based type 2 diabetes management; and £250,000 or greater for promotion of mammography attendance and for HIV prevention amongst drug users. We lacked sufficient evidence to estimate ICERs for breastfeeding promotion and mental health promotion, or to assess the impact of HRLAs on health inequalities.ConclusionsOverall, there is limited evidence suggesting that HRLAs are cost-effective in terms of changing health-related knowledge, behaviours or health outcomes. The evidence that does exist indicates that HRLAs are only cost-effective when they target behaviours likely to have a large impact on overall health-related quality of life. Further development of HRLA interventions needs to target specific population health needs where potential exists for significant improvement, and include rigorous evaluation to ensure that HRLAs provide sufficient value for money.

Project description:Utilization of internet-delivered cognitive behavioural therapy (iCBT) for treating depression and anxiety disorders in stepped-care models, such as the UK's Improving Access to Psychological Therapies (IAPT), is a potential solution for addressing the treatment gap in mental health. We investigated the effectiveness and cost-effectiveness of iCBT when fully integrated within IAPT stepped-care settings. We conducted an 8-week pragmatic randomized controlled trial with a 2:1 (iCBT intervention: waiting-list) allocation, for participants referred to an IAPT Step 2 service with depression and anxiety symptoms (Trial registration: ISRCTN91967124). The primary outcomes measures were PHQ-9 (depressive symptoms) and GAD-7 (anxiety symptoms) and WSAS (functional impairment) as a secondary outcome. The cost-effectiveness analysis was based on EQ-5D-5L (preference-based health status) to elicit the quality-adjust life year (QALY) and a modified-Client Service Receipt Inventory (care resource-use). Diagnostic interviews were administered at baseline and 3 months. Three-hundred and sixty-one participants were randomized (iCBT, 241; waiting-list, 120). Intention-to-treat analyses showed significant interaction effects for the PHQ-9 (b = -2.75, 95% CI -4.00, -1.50) and GAD-7 (b = -2.79, 95% CI -4.00, -1.58) in favour of iCBT at 8-week and further improvements observed up to 12-months. Over 8-weeks the probability of cost-effectiveness was 46.6% if decision makers are willing to pay £30,000 per QALY, increasing to 91.2% when the control-arm's outcomes and costs were extrapolated over 12-months. Results indicate that iCBT for depression and anxiety is effective and potentially cost-effective in the long-term within IAPT. Upscaling the use of iCBT as part of stepped care could help to enhance IAPT outcomes. The pragmatic trial design supports the ecological validity of the findings.

Project description:BackgroundThe Mighty Mums antenatal lifestyle intervention is a person-centered behavioral intervention focusing on nutrition and physical activity for pregnant women with obesity (body mass index [BMI] ≥30). The aim of this study was to evaluate the costs and clinical outcomes of adding the Mighty Mums intervention to standard antenatal care.MethodsParticipants in the intervention group (n = 434) received motivational talks with their midwife and a selection of physical and/or nutritional activities in addition to antenatal care. Control participants (n = 867) from adjacent geographic areas received standard antenatal care. Costs for staff, unit costs for specific activities, and registered costs for specialized antenatal care were analyzed for associations with gestational weight gain and self-reported health. Results are reported for the intention-to-treat (ITT) population and a per protocol (PP) population identified by participation in the intervention. Analyses included bootstrapped linear regressions adjusted for background characteristics that differed significantly between groups.ResultsThe average costs were SEK 9727 higher (95% confidence interval [CI]: 6677 to 12,777) among participants in the intervention group than in the control ITT population and SEK 8655 (95% CI 4586 to 12,724) higher than in the PP population. The cost increase per 1 kg reduction in gestational weight gain was SEK 12,369 in the ITT population and SEK 7209 for the PP population.ConclusionParticipation in the Mighty Mums intervention was associated with higher costs, but also reduced gestational weight gain. The cost per kilogram reduction in gestational weight gain was low, particularly in the PP population. A future decision to implement this behavioral intervention in standard care should take into account society's willingness to pay per unit reduction in gestational weight gain.Trial registrationThe study is registered at ClinicalTrials.gov , Identifier: NCT03147079 .

Project description:PurposeTo evaluate the effectiveness of peer-delivered interventions in improving clinical and psychosocial outcomes among individuals with severe mental illness (SMI) or depression.MethodsSystematic review and meta-analysis of randomised controlled trials comparing a peer-delivered intervention to treatment as usual or treatment delivered by a health professional. Random effect meta-analyses were performed separately for SMI and depression interventions.ResultsFourteen studies (10 SMI studies, 4 depression studies), all from high-income countries, met the inclusion criteria. For SMI, evidence from three high-quality superiority trials showed small positive effects favouring peer-delivered interventions for quality of life (SMD 0.24, 95 % CI 0.08-0.40, p = 0.003, I (2) = 0 %, n = 639) and hope (SMD 0.24, 95 % CI 0.02-0.46, p = 0.03, I (2) = 65 %, n = 967). Results of two SMI equivalence trials indicated that peers may be equivalent to health professionals in improving clinical symptoms (SMD -0.14, 95 % CI -0.57 to 0.29, p = 0.51, I (2) = 0 %, n = 84) and quality of life (SMD -0.11, 95 % CI -0.42 to 0.20, p = 0.56, I (2) = 0 %, n = 164). No effect of peer-delivered interventions for depression was observed on any outcome.ConclusionsThe limited evidence base suggests that peers may have a small additional impact on patient's outcomes, in comparison to standard psychiatric care in high-income settings. Future research should explore the use and applicability of peer-delivered interventions in resource poor settings where standard care is likely to be of lower quality and coverage. The positive findings of equivalence trials demand further research in this area to consolidate the relative value of peer-delivered vs. professional-delivered interventions.
