RESUMO

BACKGROUND: Depression and anxiety are increasingly prevalent in adolescents. The Brief Educational Workshops in Secondary Schools Trial investigated the effectiveness of a brief accessible stress workshop programme for 16-18-year-olds. We aimed to investigate the clinical effectiveness and cost-effectiveness of the DISCOVER cognitive behavioural therapy (CBT) workshop on symptoms of depression in 16-18-year-olds at 6 months compared with treatment-as-usual. METHODS: We conducted a multicentre, cluster randomised controlled trial in UK schools or colleges with sixth forms to evaluate clinical effectiveness and cost-effectiveness of a brief CBT workshop (DISCOVER) compared with treatment-as-usual. We planned to enrol 60 schools and 900 adolescents, using a self-referral system to recruit participants. Schools were randomised in a 1:1 ratio for participants to receive either the DISCOVER workshop or treatment-as-usual, stratified by site and balanced on school size and index of multiple deprivation. Participants were included if they were 16-18 years old, attending for the full school year, seeking help for stress, and fluent in English and able to provide written informed consent. The outcome assessors, senior health economist, senior statistician, and chief investigator were masked. People with lived experience were involved in the study. The primary outcome was depression symptoms measured with the Mood and Feelings Questionnaire (MFQ) at 6-month follow-up, in the intention-to-treat population of all participants with full covariate data. The trial was registered with the ISRCTN registry (ISRCTN90912799). FINDINGS: 111 schools were invited to participate in the study, seven were deemed ineligible, and 47 did not provide consent. Between Oct 4, 2021, and Nov 10, 2022, 933 students at 57 schools were screened for eligibility, seven were not eligible for inclusion, and 26 did not attend the baseline meeting and assessment, resulting in 900 adolescents participating in the study. The DISCOVER group included 443 participants (295 [67%] female and 136 [31%] male) and the treatment-as-usual group included 457 participants (346 [76%] female and 92 [20%] male). 468 (52%) of the 900 participants were White, and the overall age of the participants was 17·2 years (SD 0·6). 873 (97%) adolescents were followed up in the intention-to-treat population. The primary intention-to-treat analysis (n=854) found an adjusted mean difference in MFQ of -2·06 (95% CI -3·35 to -0·76; Cohen's d=-0·17; p=0·0019) at the 6-month follow-up, indicating a clinical improvement in the DISCOVER group. The probability that DISCOVER is cost- effective compared with treatment-as-usual ranged from 61% to 78% at a £20 000 to £30 000 per quality-adjusted life-year threshold. Nine adverse events (two of which were classified as serious) were reported in the DISCOVER group and 14 (two of which were classified as serious) were reported in the treatment-as-usual group. INTERPRETATION: Our findings indicate that the DISCOVER intervention is modestly clinically effective and economically viable and could be a promising early intervention in schools. Given the importance of addressing mental health needs early in this adolescent population, additional research is warranted to explore this intervention.

RESUMO

BACKGROUND: The Brief Educational Workshops in Secondary Schools Trial (BESST) is an England-wide school-based cluster randomised controlled trial assessing the clinical and cost-effectiveness of an open-access psychological workshop programme (DISCOVER) for 16-18-year-olds. This baseline paper describes the self-referral and other recruitment processes used in this study and the baseline characteristics of the enrolled schools and participants. METHOD: We enrolled 900 participants from 57 Secondary schools across England from 4th October 2021 to 10th November 2022. Schools were randomised to receive either the DISCOVER day-long Stress workshop or treatment as usual which included signposting information. Participants will be followed up for 6 months with outcome data collection at baseline, 3-month, and 6-month post randomisation. RESULTS: Schools were recruited from a geographically and ethnically diverse sample across England. To reduce stigma, students were invited to self-refer into the study if they wanted help for stress. Their mean age was 17.2 (SD = 0.6), 641 (71%) were female and 411 (45.6%) were from ethnic minority groups. The general wellbeing of our sample measured using the Mood and Feelings Questionnaire (MFQ) found 314 (35%) of students exhibited symptoms of depression at baseline. Eighty percent of students reported low wellbeing on the Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) suggesting that although the overall sample mean is below the cut-off for depression, the self-referral approach used in this study supports distressed students in coming forward. CONCLUSION: The BESST study will continue to follow up participants to collect outcome data and results will be analysed once all the data have been collected.

RESUMO

Background: Acamprosate is an effective and cost-effective medication for alcohol relapse prevention but poor adherence can limit its full benefit. Effective interventions to support adherence to acamprosate are therefore needed. Objectives: To determine the effectiveness of Medication Management, with and without Contingency Management, compared to Standard Support alone in enhancing adherence to acamprosate and the impact of adherence to acamprosate on abstinence and reduced alcohol consumption. Design: Multicentre, three-arm, parallel-group, randomised controlled clinical trial. Setting: Specialist alcohol treatment services in five regions of England (South East London, Central and North West London, Wessex, Yorkshire and Humber and West Midlands). Participants: Adults (aged 18 years or more), an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnosis of alcohol dependence, abstinent from alcohol at baseline assessment, in receipt of a prescription for acamprosate. Interventions: (1) Standard Support, (2) Standard Support with adjunctive Medication Management provided by pharmacists via a clinical contact centre (12 sessions over 6 months), (3) Standard Support with adjunctive Medication Management plus Contingency Management that consisted of vouchers (up to £120) to reinforce participation in Medication Management. Consenting participants were randomised in a 2 : 1 : 1 ratio to one of the three groups using a stratified random permuted block method using a remote system. Participants and researchers were not blind to treatment allocation. Main outcome measures: Primary outcome: self-reported percentage of medication taken in the previous 28 days at 6 months post randomisation. Economic outcome: EuroQol-5 Dimensions, a five-level version, used to calculate quality-adjusted life-years, with costs estimated using the Adult Service Use Schedule. Results: Of the 1459 potential participants approached, 1019 (70%) were assessed and 739 (73 consented to participate in the study, 372 (50%) were allocated to Standard Support, 182 (25%) to Standard Support with Medication Management and 185 (25%) to Standard Support and Medication Management with Contingency Management. Data were available for 518 (70%) of participants at 6-month follow-up, 255 (68.5%) allocated to Standard Support, 122 (67.0%) to Standard Support and Medication Management and 141 (76.2%) to Standard Support and Medication Management with Contingency Management. The mean difference of per cent adherence to acamprosate was higher for those who received Standard Support and Medication Management with Contingency Management (10.6%, 95% confidence interval 19.6% to 1.6%) compared to Standard Support alone, at the primary end point (6-month follow-up). There was no significant difference in per cent days adherent when comparing Standard Support and Medication Management with Standard Support alone 3.1% (95% confidence interval 12.8% to -6.5%) or comparing Standard Support and Medication Management with Standard Support and Medication Management with Contingency Management 7.9% (95% confidence interval 18.7% to -2.8%). The primary economic analysis at 6 months found that Standard Support and Medication Management with Contingency Management was cost-effective compared to Standard Support alone, achieving small gains in quality-adjusted life-years at a lower cost per participant. Cost-effectiveness was not observed for adjunctive Medication Management compared to Standard Support alone. There were no serious adverse events related to the trial interventions reported. Limitations: The trial's primary outcome measure changed substantially due to data collection difficulties and therefore relied on a measure of self-reported adherence. A lower than anticipated follow-up rate at 12 months may have lowered the statistical power to detect differences in the secondary analyses, although the primary analysis was not impacted. Conclusions: Medication Management enhanced with Contingency Management is beneficial to patients for supporting them to take acamprosate. Future work: Given our findings in relation to Contingency Management enhancing Medication Management adherence, future trials should be developed to explore its effectiveness and cost-effectiveness with other alcohol interventions where there is evidence of poor adherence. Trial registration: This trial is registered as ISRCTN17083622 https://doi.org/10.1186/ISRCTN17083622.

Many people who are trying to stop drinking alcohol can find it difficult to remain alcohol free. There is a medication called acamprosate (Campral) that can reduce cravings thereby increasing the likelihood of abstinence. However, some people have trouble taking the right amount of acamprosate tablets needed every day at the right time, preferably at mealtimes. This means the medication is not as effective. We have tested some new ways to help support people taking acamprosate. We tested three different strategies to find the best way to support people taking acamprosate. We recruited 739 people aged 18 and over who were receiving alcohol treatment to stop drinking and were taking acamprosate. We randomly allocated these people to three groups. The first was Standard Support, the usual support people receive when taking acamprosate. The second group received Standard Support plus Medication Management. This consisted of 12 telephone calls over 6 months with a trained pharmacist to discuss the importance of taking the right amount of the medication, how the medication works and strategies to help people take the medication correctly. The third group received Standard Support, Medication Management and Contingency Management. This involved giving people shopping vouchers for participating with Medication Management calls. The maximum value of vouchers per person was £120. People who were in the group receiving Medication Management and Contingency Management took a greater number of acamprosate tablets. We also found that Medication Management plus Contingency Management was more cost-effective; there were greater gains in health with a smaller cost per person compared to Standard Support alone. This shows that there is likely to be a benefit to patients of Medication Management plus Contingency Management for supporting people taking acamprosate.

RESUMO

BACKGROUND: Children's conduct and emotional problems increased during the COVID-19 pandemic. OBJECTIVE: We tested whether a smartphone parenting support app, Parent Positive, developed specifically for this purpose, reversed these effects in a cost-effective way. Parent Positive includes 3 zones. Parenting Boosters (zone 1) provided content adapted from standard face-to-face parent training programs to tackle 8 specific challenges identified by parents and parenting experts as particularly relevant for parents during the pandemic. The Parenting Exchange (zone 2) was a parent-to-parent and parent-to-expert communication forum. Parenting Resources (zone 3) provided access to existing high-quality web-based resources on a range of additional topics of value to parents (eg, neurodevelopmental problems, diet, and sleep). METHODS: Supporting Parents And Kids Through Lockdown Experiences (SPARKLE), a randomized controlled trial, was embedded in the UK-wide COVID-19: Supporting Parents, Adolescents and Children during Epidemics (Co-SPACE) longitudinal study on families' mental health during the pandemic. Parents of children aged 4 to 10 years were randomized 1:1 to Parent Positive or follow-up as usual (FAU) between May 19, 2021, and July 26, 2021. Parent Positive provided advice on common parenting challenges and evidence-based web-based resources and facilitated parent-to-parent and expert-to-parent support. Child conduct and emotional problems and family well-being were measured before randomization (T1) and at 1 (T2) and 2 (T3) months after randomization. Service use, costs, and adverse events were measured, along with app use and satisfaction. The primary outcome was T2 parent-reported child conduct problems, which were analyzed using linear mixed regression models. RESULTS: A total of 320 participants were randomized to Parent Positive, and 326 were randomized to FAU. The primary outcome analysis included 79.3% (512/646) of the participants (dropout: 84/320, 26% on Parent Positive and 50/326, 15% on FAU). There were no statistically significant intervention effects on conduct problems at either T2 (standardized effect=-0.01) or T3 (secondary outcome; standardized effect=-0.09) and no moderation by baseline conduct problems. Significant intervention-related reductions in emotional problems were observed at T2 and T3 (secondary outcomes; standardized effect=-0.13 in both cases). Parent Positive, relative to FAU, was associated with more parental worries at T3 (standardized effect=0.14). Few intervention-attributable adverse events were reported. Parent Positive was cost-effective once 4 outliers with extremely high health care costs were excluded. CONCLUSIONS: Parent Positive reduced child emotional problems and was cost-effective compared with FAU once outliers were removed. Although small when considered against targeted therapeutic interventions, the size of these effects was in line with trials of nontargeted universal mental health interventions. This highlights the public health potential of Parent Positive if implemented at the community level. Nevertheless, caution is required before making such an interpretation, and the findings need to be replicated in large-scale, whole-community studies.

RESUMO

OBJECTIVES: Cost-effectiveness analysis of two 12-week contingency management (CM) schedules targeting heroin abstinence or attendance at weekly keyworker appointments for opioid agonist treatment compared with treatment as usual (TAU). METHODS: A cost-effectiveness analysis was conducted alongside a cluster randomized trial of 552 patients from 34 clusters (drug treatment clinics) randomly allocated 1:1:1 to opioid agonist treatment plus weekly keyworker appointments with (1) CM targeted at heroin abstinence (CM abstinence), (2) CM targeted at on-time attendance at weekly appointments (CM attendance), or (3) no CM (TAU). The primary cost-effectiveness analysis at 24 weeks after randomization took a societal cost perspective with effects measured in heroin-negative urine samples. RESULTS: At 24 weeks, mean differences in weekly heroin-negative urine results compared with TAU were 0.252 (95% confidence interval [CI] -0.397 to 0.901) for CM abstinence and 0.089 (95% CI -0.223 to 0.402) for CM attendance. Mean differences in costs were £2562 (95% CI £32-£5092) for CM abstinence and £317 (95% CI -£882 to £1518) for CM attendance. Incremental cost-effectiveness ratios were £10 167 per additional heroin-free urine for CM abstinence and £3562 for CM attendance with low probabilities of cost-effectiveness of 3.5% and 36%, respectively. Results were sensitive to timing of follow-up for CM attendance, which dominated TAU (better outcomes, lower costs) at 12 weeks, with an 88.4% probability of being cost-effective. Probability of cost-effectiveness remained low for CM abstinence (8.6%). CONCLUSIONS: Financial incentives targeted toward heroin abstinence and treatment attendance were not cost-effective over the 24-week follow-up. Nevertheless, CM attendance was cost-effective over the treatment period (12 weeks), when participants were receiving keyworker appointments and incentives.

RESUMO

This systematic review is to evaluate the effectiveness and cost-effectiveness of mental health interventions delivered by frontline health care workers in disasters and public health emergencies. Six databases and trial registries were searched, and manual searches were conducted. Of the 221 studies identified, 21 were included. Meta-analyses assessed differences between the intervention and control in terms of PTSD outcomes. Eleven studies of 1802 participants were incorporated in the meta-analysis. Interventions delivered or prompted by specialist health care workers showed significant and large effects in improving PTSD-related symptoms with a SMD = 0.99 (95% CI: 0.42-1.57, p = 0.0007). Interventions delivered or prompted by frontline non-specialist health care workers showed significant but small effects in improving PTSD-related symptoms with SMD of 0.25 (95% CI: 0.11-0.39; p = 0.0007). The results showed that most mental health interventions delivered by frontline health care workers effectively supported affected people. Mental health interventions delivered by mental health care professionals are effective in reducing PTSD-related disorders in natural disasters. Future adequately powered RCTs are needed to evaluate the effectiveness of mental health interventions delivered by trained non-specialists. Economic modelling may be useful to estimate cost effectiveness in low- and middle-income countries given the difficulties of conducting studies in disaster and emergency settings.

RESUMO

Anxiety and depression are increasingly prevalent in adolescents, often causing daily distress and negative long-term outcomes. Despite the significant and growing burden, less than 25% of those with probable diagnosis of anxiety and depression are receiving help in England. Significant barriers to help-seeking exist in this population, with a scarcity of easily accessible, effective, and cost-effective interventions tailored specially for this age group. One intervention that has been shown to be feasible to deliver and with the promise of reducing stress in this age group is a school-based stress workshop programme for 16-18-year-olds (herein called DISCOVER). The next step is to rigorously assess the effectiveness, and cost-effectiveness, of the DISCOVER intervention in a fully powered cluster randomised controlled trial (cRCT). If found to be clinically and cost-effective, DISCOVER could be scaled up as a service model UK-wide and have a meaningful impact on the mental health of adolescents across the country.Trial registration: ISRCTN registry ISRCTN90912799.

RESUMO

BACKGROUND: Looked-after children are at risk of suboptimal attachment patterns and reactive attachment disorder. However, access to interventions varies widely and there are no evidence-based interventions for this disorder. OBJECTIVES: (1) To adapt an existing video-feedback intervention to meet the specific needs of foster children in the UK with reactive attachment symptoms, (2) to conduct a case series to road-test the treatment manual and study procedures, (3) to conduct a scoping study of the key hurdles in a pilot trial and (4) to conduct a pilot randomised controlled trial of the adapted intervention to determine the feasibility of a future full-scale trial. DESIGN: This was a mixed-methods study. The adapted treatment manual was developed with expert input and tested on a small case series. Qualitative interviews with key stakeholders were used in the scoping study in preparation for the trial and later with foster carers who received the new intervention. The final stage was a feasibility and pilot randomised controlled trial of the new intervention, compared with usual care. Researchers assessing the outcomes were blinded to group assignment. SETTING: The study was set in outpatient child and adolescent mental health services and partner social services departments. Sites included urban and rural/semirural areas. PARTICIPANTS: Participants were foster carers with children aged ≤ 6 years presenting with difficulties in the domain of reactive attachment disorder. Key stakeholders included children's services managers and mental health service practitioners in the scoping study. Foster carers who received the modified intervention participated in qualitative interviews. INTERVENTION: The video-feedback intervention to promote positive parenting and sensitive discipline is an extensively evaluated and effective treatment approach. This intervention was modified (based on the adapted version for foster care in the Netherlands) to suit the needs of young children with reactive attachment symptoms in foster care in the UK and was delivered to improve the sensitive responding of foster carers, foster carer-child relationships and child outcomes. The modified intervention was delivered in-home by trained mental health professionals over a period of 4-6 months. MAIN OUTCOME MEASURE: The main outcome was reactive attachment symptom scores on the Disturbances of Attachment Interview. RESULTS: A series of minor changes to the intervention programme were introduced, which focused on improving its suitability for the UK foster care context. Challenges in recruitment meant that, despite numerous modifications to the protocol and the inclusion of additional sites, only 30 families (target, n = 40) were recruited to the randomised controlled trial (15 allocated to each group). However, most other trial parameters were deemed feasible and acceptable, particularly the high levels of data and treatment completeness. All randomised families were available for baseline analyses, but two in the treatment arm were not available for post-treatment analyses. The revised intervention was positively received by practitioners and foster carers. LIMITATIONS: Only three-quarters of the target sample size was recruited. Furthermore, the sites' own exclusion of potential participants and the low return rates of screening questionnaires raise the possibility of non-randomness of non-responses. CONCLUSION: A larger-scale trial may be feasible, but only if recruitment barriers can be overcome. Dedicated resources to support recruitment within local authorities and wider inclusion criteria are recommended. Central resourcing of intervention capacity to supplement NHS staff is also recommended. TRIAL REGISTRATION: This trial is registered as ISRCTN18374094. FUNDING: This project was funded by the National Institute for Health and Care Research ( NIHR ) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 35.

Children in foster care typically have had a very difficult start in life, often as a result of abuse or neglect within their family of origin, and separation from caregivers. These children can find it difficult to trust new adults, and in some cases difficulties in attachment may justify a diagnosis of reactive attachment disorder. This disorder is a pattern of behaviour among young children who have received extremely insufficient early care, whereby they fail to seek or respond to comfort from carers when hurt or distressed, and they can be very withdrawn. There are currently no evidence-based treatments for reactive attachment disorder. The Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline is a treatment programme that was developed to promote secure attachments in young children and to help parents deal with difficult behaviour. A practitioner films the child and parent interacting at home and provides feedback in the following session. This treatment was previously adapted for use in foster care in the Netherlands. In this study, we modified the treatment further to ensure that it appropriately addressed the needs of young children in foster care in the UK who present with reactive attachment disorder symptoms. We then worked with local authorities and linked mental health services to develop a system for identifying young children in foster care in need of this treatment. Finally, we conducted a small (pilot) study to gather information about the best way to provide the modified treatment in this context. The revised treatment was positively received by practitioners and foster carers. The majority of the processes involved in running a trial also worked well (e.g. good levels of attendance at assessments and at the treatment sessions). However, we encountered significant difficulties in recruiting foster carers to the study. We concluded that a full-scale trial would be very valuable, and could potentially be undertaken if difficulties with recruitment are overcome. We recommend that greater resources be provided to local authorities to help them engage and recruit foster carers.

RESUMO

BACKGROUND: Anorexia nervosa (AN) is a serious and disabling mental disorder with a high disease burden. In a proportion of cases, intensive hospital-based treatments, i.e. inpatient or day patient treatment, are required, with day patient treatment often being used as a 'step-down' treatment after a period of inpatient treatment. Demand for such treatment approaches has seen a sharp rise. Despite this, the relative merits of these approaches for patients, their families, and the NHS and wider society are relatively unknown. This paper describes the rationale for, and protocol of, a two-arm multi-centre open-label parallel group non-inferiority randomised controlled trial, evaluating the effectiveness and cost-effectiveness of these two intensive treatments for adults with severe AN: inpatient treatment as usual and a stepped care day patient approach (the combination of day patient treatment with the option of initial inpatient treatment for medical stabilisation). The main aim of this trial is to establish whether, in adults with severe AN, a stepped care day patient approach is non-inferior to inpatient treatment as usual in relation to improving body mass index (BMI) at 12 months post-randomisation. METHODS: 386 patients with a Diagnostic and Statistical Manual 5th edition diagnosis of severe AN or related disorder, with a BMI of ≤16 kg/m2 and in need of intensive treatment will be randomly allocated to either inpatient treatment as usual or a stepped care day patient approach. Patients in both groups will receive treatment until they reach a healthy weight or get as close to this point as possible. Assessments will be conducted at baseline (prior to randomisation), and at 6 and 12 months post-randomisation, with additional monthly symptom monitoring. The primary outcome will be BMI at the 12-month post-randomisation assessment. Other outcomes will include psychosocial adjustment; treatment motivation, expectations and experiences; cost-effectiveness; and carer burden. DISCUSSION: The results of this study will provide a rigorous evaluation of two intensive treatment approaches which will inform future national and international treatment guidelines and service provision.

RESUMO

BACKGROUND: Chronic cough is a common reason for medical consultations and is associated with considerable physical and psychological morbidity. This study investigated healthcare use and cost in chronic cough and assessed its relationship with cough severity, health status, objective cough frequency (CF), and anxiety and depression. METHODS: This was a prospective study of consecutive patients with chronic cough from a specialist clinic who completed a cough severity visual analogue scale (VAS), cough-specific health status (Leicester Cough Questionnaire; LCQ) and general health status EuroQol EQ-5D-5L, Generalized Anxiety Disorder (GAD7), Patient Health Questionnaire (PHQ9), and 24-hour objective CF monitoring with Leicester Cough Monitor (LCM). Case notes were reviewed for cough-specific healthcare use 12 months before and after the first cough clinic consultation. Resource use included general practitioner and hospital clinic visits, investigations, and treatments. Unit costs for healthcare use were derived predominantly from National Health Service Reference Costs. RESULTS: One hundred participants with chronic cough were recruited (69% female, median duration 3 years, mean age 58 years). The diagnoses of cough were unexplained (57%), refractory (27%), and other (16%). Cough severity, health status, and CF were: median (IQR) VAS = 59.5 (30-79) mm, mean (SD) LCQ = 11.9 (4.0), mean (SD) EQ-5D-5L = 0.846 (0.178), and geometric mean (SD) CF = 15.3 (2.5) coughs/hr, respectively. The mean (SD) total cost per individual for cough-related healthcare utilization was £1,663 (747). Diagnostic investigations were the largest contributor to cost (63%), followed by cough clinic consultations (25%). In multivariate analysis, anxiety (GAD7) and cough-related health status (LCQ) were associated with increased cost (p ≤.001 and .037). CONCLUSION: Healthcare cost associated with chronic cough are largely due to diagnostic investigations and clinic consultations. The predictors of costs were health status (LCQ) and anxiety. Further studies should investigate the optimal management protocols for patients with chronic cough.

RESUMO

BACKGROUND: The number of women of childbearing age with Type 2 diabetes(T2DM) is increasing, and they now account for > 50% of pregnancies in women with pre-existing diabetes. Diabetes pregnancies without adequate pre-pregnancy care have higher risk for poor outcomes (miscarriages, birth-defects, stillbirths) and are associated with increased complications (caesarean deliveries, macrosomic babies, neonatal intensive-care admissions). The risks and costs of these pregnancies can be reduced with pregnancy preparation (HbA1c, ≤ 6.5%, 5 mg folic acid and stopping potentially harmful medicines). However, 90% of women with T2DM, most of whom are based in primary care, are not adequately prepared for pregnancy. This study will evaluate a programme of primary care-based interventions (decision-support systems; pre-pregnancy care-pathways; pregnancy-awareness resources; professional training; and performance monitoring) to improve pregnancy preparation in women with T2DM. METHODS: The study aims to optimise the programme interventions and estimate their impact on pregnancy preparation, pre-pregnancy care uptake and pregnancy outcomes. To evaluate this multimodal intervention, we will use a multi-method research design following Complex Adaptive Systems (CAS) theory, refining the interventions iteratively during the study. Thirty GP practices with ≥ 25 women with T2DM of reproductive age (18-45 years) from two South London boroughs will be exposed to the intervention. This will provide > 750 women with an estimated pregnancy incidence of 80-100 to study. The research involves: a clinical audit of processes and outcomes; a process evaluation informing intervention feasibility, implementation, and behaviour change; and a cost-consequences analysis informing future economic evaluation. Performance data will be collected via audits of GP systems, hospital antenatal clinics and pregnancy outcomes. Following CAS theory, we will use repeated measurements to monitor intervention impact on pregnancy preparation markers at 4-monthly intervals over 18-months. We will use performance and feasibility data to optimise intervention effects iteratively. The target performance for the intervention is a 30% increase in the proportion of women meeting pre-pregnancy care criteria. DISCUSSION: The primary output will be development of an integrated programme of interventions to improve pregnancy preparation, pre-pregnancy care uptake, and reduce adverse pregnancy outcomes in women with T2DM. We will also develop an implementation plan to support the introduction of the interventions across the NHS. TRIAL REGISTRATION: ISRCTN47576591 ; February 8, 2022.

RESUMO

BACKGROUND: In the UK, children with high levels of hyperactivity, impulsivity and inattention referred to clinical services with possible attention-deficit/hyperactivity disorder (ADHD) often wait a long time for specialist diagnostic assessment. Parent training (PT) has the potential to support parents during this difficult period, especially regarding the management of challenging and disruptive behaviours that often accompany ADHD. However, traditional face-to-face PT is costly and difficult to organise in a timely way. We have created a low-cost, easily accessible PT programme delivered via a phone app, Structured E-Parenting Support (STEPS), to address this problem. The overall OPTIMA programme will evaluate the efficacy and cost-effectiveness of STEPS as a way of helping parents manage their children behaviour while on the waitlist. To ensure the timely and efficient evaluation of STEPS in OPTIMA, we have worked with children's health services to implement a remote strategy for recruitment, screening and assessment of recently referred families. Part of this strategy is incorporated into routine clinical practice and part is OPTIMA specific. Here, we present the protocol for Phase 1 of OPTIMA-a study of the feasibility of this remote strategy, as a basis for a large-scale STEPS randomised controlled trial (RCT). METHODS: This is a single arm observational feasibility study. Participants will be parents of up to 100 children aged 5-11 years with high levels of hyperactivity/impulsivity, inattention and challenging behaviour who are waiting for assessment in one of five UK child and adolescent mental health or behavioural services. Recruitment, consenting and data collection will occur remotely. The primary outcome will be the rate at which the families, who meet inclusion criteria, agree in principle to take part in a full STEPS RCT. Secondary outcomes include acceptability of remote consenting and online data collection procedures; the feasibility of collecting teacher data remotely within the required timeframe, and technical difficulties with completing online questionnaires. All parents in the study will receive access to STEPS. DISCUSSION: Establishing the feasibility of our remote recruitment, consenting and assessment strategy is a pre-requisite for the full trial of OPTIMA. It can also provide a model for future trials conducted remotely.

RESUMO

Introduction: There is insufficient evidence on the effectiveness and cost-effectiveness of psychological interventions to enhance frontline responders' mental health proficiency and competence in emergency settings. This paper describes the methods for the evaluation of the effectiveness and cost-effectiveness of Psychological First Aid training, to determine whether the intervention is effective and cost-effective as a mental health intervention in public health emergencies. A pilot to evaluate the acceptability of the PFA training found participants were either satisfied (55.6%) or extremely satisfied (44.4%) with the training program. Method: This paper describes the protocol for a cluster randomized two-arm controlled trial. A total of 1,399 non-specialist health care workers will be recruited in 42 hospitals and health care centers across six provinces in China. Participants will be assigned according to hospital or health care center site to one of two groups (n = 699 for intervention group and 709 for control group) to receive system based PFA training or PFA training as usual. Both groups will receive one-day of training, comprising six modules including PFA core concepts, knowledge, skills and practice. Their knowledge, skills, competency, self-efficacy, resilience, and professional quality of life will be assessed immediately after the training; and reassessed after 1 and 2 months. Analysis: For effectiveness outcomes, repeated measures will be used in a multi-level linear mixed model. The pooled standard deviations will be used to calculate the effect sizes (Cohen's d) within and between groups. Appropriate statistical tests will be used to explore differences between intervention and control groups. For economic outcomes, a health service sector perspective will be adopted, with intervention costs and outcomes collected prospectively. Within-trial cost-effectiveness analysis (CEA) will quantify the incremental costs and PFA proficiency gains of the intervention compared with training as usual at 2 months post training. CEA will present results as cost per unit of mental health proficiency gained. A cost-utility analysis (CUA) model will extend the population to emergency health service users.in order to identify potential for incremental cost offsets attributable to mental health improvement arising from intervention. Intervention costs and effects will be extrapolated to the population of patients who receive the emergency health service in clinical wards and will be modeled over the cohort's lifetime. Modeled CUA results will be calculated as quality-adjusted life-years saved and healthcare cost savings in preventing mental disorders. Ethics and dissemination: Ethics approval was obtained from the Second Xiangya Hospital, Central South University Clinical Research Ethics Committee (2021) Ethical Review [Clinical Research] #067). Data about the economic evaluation of the intervention will be stored in the KCL OneDrive at King's College London, UK. The trial protocol was registered with the China Clinical Trials Registry: ChiCTR2200060464. Study findings will be disseminated through peer-reviewed academic papers, and participating hospitals.

RESUMO

INTRODUCTION: Most individuals treated for heroin use disorder receive opioid agonist treatment (OAT)(methadone or buprenorphine). However, OAT is associated with high attrition and persistent, occasional heroin use. There is some evidence for the effectiveness of contingency management (CM), a behavioural intervention involving modest financial incentives, in encouraging drug abstinence when applied adjunctively with OAT. UK drug services have a minimal track record of applying CM and limited resources to implement it. We assessed a CM intervention pragmatically adapted for ease of implementation in UK drug services to promote heroin abstinence among individuals receiving OAT. DESIGN: Cluster randomised controlled trial. SETTING AND PARTICIPANTS: 552 adults with heroin use disorder (target 660) enrolled from 34 clusters (drug treatment clinics) in England between November 2012 and October 2015. INTERVENTIONS: Clusters were randomly allocated 1:1:1 to OAT plus 12× weekly appointments with: (1) CM targeted at opiate abstinence at appointments (CM Abstinence); (2) CM targeted at on-time attendance at appointments (CM Attendance); or (3) no CM (treatment as usual; TAU). Modifications included monitoring behaviour weekly and fixed incentives schedule. MEASUREMENTS: Primary outcome: heroin abstinence measured by heroin-free urines (weeks 9-12). SECONDARY OUTCOMES: heroin abstinence 12 weeks after discontinuation of CM (weeks 21-24); attendance; self-reported drug use, physical and mental health. RESULTS: CM Attendance was superior to TAU in encouraging heroin abstinence. Odds of a heroin-negative urine in weeks 9-12 was statistically significantly greater in CM Attendance compared with TAU (OR=2.1; 95% CI 1.1 to 3.9; p=0.030). CM Abstinence was not superior to TAU (OR=1.6; 95% CI 0.9 to 3.0; p=0.146) or CM Attendance (OR=1.3; 95% CI 0.7 to 2.4; p=0.438) (not statistically significant differences). Reductions in heroin use were not sustained at 21-24 weeks. No differences between groups in self-reported heroin use. CONCLUSIONS: A pragmatically adapted CM intervention for routine use in UK drug services was moderately effective in encouraging heroin abstinence compared with no CM only when targeted at attendance. CM targeted at abstinence was not effective. TRIAL REGISTRATION NUMBER: ISRCTN 01591254.

RESUMO

BACKGROUND: This study evaluated the cost effectiveness of an intensive lifestyle modification (LSM) intervention delivered by peer educators for the prevention of type 2 diabetes mellitus in a young at-risk population in a low healthcare resource setting. OBJECTIVE: The aim of this study was to evaluate the short-term and long-term cost effectiveness of an intensive lifestyle modification intervention for type 2 diabetes prevention in a young urban at-risk population in Sri Lanka. METHODS: This was an economic evaluation using cost and outcome data from a randomized controlled trial. We randomized 3539 healthy individuals aged 5-40 years with risk factors for type 2 diabetes to either 3-monthly (P-LSM n = 1727) or 12-monthly (C-LSM n = 1812) peer-educator advice aimed at reducing weight, improving diet, reducing psychological stress and increasing physical activity. A cost-effectiveness analysis was conducted from a health system perspective with outcomes expressed as disability-adjusted life-years (DALYs). Intervention costs and outcomes were collected during a median clinical trial period of 3 years and extrapolated to a lifetime horizon using economic modelling. Uncertainty in the lifetime model was explored by structural and probabilistic sensitivity analyses. RESULTS: The costs of the more intensive peer support programme were partially offset by reduced costs of type 2 diabetes complications recorded over the trial period and completely offset by lifetime cost savings of 6000 LKR. The more intensive P-LSM also averted more DALYs, estimated at 0.456 DALYs over the lifetime of participants. CONCLUSIONS: In a young at-risk Sri Lanka population, an intensive LSM programme was cost effective, averting more DALYs at an acceptable additional cost than a much less intensive LSM programme. Early intervention in young at-risk people represents good value for money from the Sri Lankan health care payer perspective.

RESUMO

OBJECTIVES: Given the limited diagnostic accuracy of radiographs on presentation to the emergency department (ED), the management of suspected scaphoid fractures remains clinically challenging and poses an unknown economic burden to healthcare systems. We aimed to evaluate the cost-effectiveness of immediate magnetic resonance imaging (MRI) in the management of patients presenting with suspected scaphoid fracture to an ED in England. METHODS: A pragmatic, randomized, single-center trial compared the use of immediate MRI in the ED against standard care with radiographs only. Participants' use of healthcare services and costs were estimated from primary care and secondary care databases and questionnaires at baseline, 1, 3, and 6 months postrecruitment. Costs were compared using generalized linear models and combined with quality-adjusted life years (QALYs, based on the EQ-5D-5L) to estimate cost-effectiveness at 6 months postrecruitment. Cost-effectiveness acceptability curves and bootstrapping techniques were used to estimate the probability of cost-effectiveness at different willingness-to-pay (WTP) thresholds. Four deterministic sensitivity scenarios were considered around key parameters. RESULTS: The MRI intervention dominated standard care in the base case and all 4 deterministic sensitivity scenarios, costing less and achieving more QALY gains, with a probability of 100% of being cost-effective at 6 months using the conventional United Kingdom WTP thresholds of £20 000 to £30 000 per QALY. CONCLUSION: The use of immediate MRI is a cost-effective intervention in the management of suspected scaphoid fractures in a Central Hospital in London. Routine clinical practice at our institution has been changed to include the intervention.

RESUMO

The majority of people receiving treatment for their heroin addiction, are prescribed methadone; for which there is an extensive evidence base. When treatment starts, people take their daily dose of methadone under supervision at a community pharmacy. Supervision guarantees methadone is taken as directed by the individual for whom it has been prescribed, helps to ensure individuals take their correct dose every day, and safeguards against diversion and overdose. However, individuals often fail to attend the pharmacy to take their methadone. Each missed dose is of concern. If a patient misses their daily dose of methadone, they will start to experience opiate withdrawal and cravings and are more likely to use heroin. If they miss three days dose, there are concerns that they may lose tolerance to the drug and may be at risk of overdose when the next dose is taken. Hence there is an urgent need to develop effective interventions for medication adherence. Research suggests that incentive-based medication adherence interventions may be very effective, but there are few controlled trials and the provision of incentives requires time and organisational systems which can be challenging in pharmacies. The investigators have developed the technology to deliver incentives by mobile telephone. This cluster randomised trial will test the feasibility of conducting a future trial evaluating the clinical and cost effectiveness of using telephone delivered incentives (praise and modest financial rewards via text messaging) to encourage adherence with supervised consumption of methadone in community pharmacies. Three drug services (each with two or three community pharmacies supervising methadone consumption that will enrol 20 individuals, a total of 60 participants) will be recruited and randomly allocated to deliver either i) telephone delivered incentives, ii) telephone delivered reminders or iii) no telephone system. Acceptability, recruitment, follow-up, and suitable measures of clinical and cost effectiveness will be assessed. Findings from this feasibility study will be assessed against stated progression criteria and used to inform a future confirmatory trial of the clinical and cost effectiveness of telephone delivered incentives to encourage medication adherence. TRIAL REGISTRATION: ISRCTN58958179 (retrospectively registered).

RESUMO

BACKGROUND: Refractory depression is a major contributor to the economic burden of depression. Radically open dialectical behaviour therapy (RO DBT) is an unevaluated new treatment targeting overcontrolled personality, common in refractory depression, but it is not yet known whether the additional expense of RO DBT is good value for money.AimsTo estimate the cost-effectiveness of RO DBT plus treatment as usual (TAU) compared with TAU alone in people with refractory depression (trial registration: ISRCTN85784627). METHOD: We undertook a cost-effectiveness analysis alongside a randomised trial evaluating RO DBT plus TAU versus TAU alone for refractory depression in three UK secondary care centres. Our economic evaluation, 12 months after randomisation, adopted the perspective of the UK National Health Service (NHS) and personal social services. It evaluated cost-effectiveness by comparing the net cost of RO DBT with the net gain in quality-adjusted life-years (QALYs), estimated using the EQ-5D-3L measure of health-related quality of life. RESULTS: The additional cost of RO DBT plus TAU compared with TAU alone was £7048 and was associated with a difference of 0.032 QALYs, yielding an incremental cost-effectiveness ratio (ICER) of £220 250 per QALY. This ICER was well above the National Institute for Health and Care Excellence (NICE) upper threshold of £30 000 per QALY. A cost-effectiveness acceptability curve indicated that RO DBT had a zero probability of being cost-effective compared with TAU at the NICE £30 000 threshold. CONCLUSIONS: In its current resource-intensive form, RO DBT is not a cost-effective use of resources in the UK NHS.Declaration of interestR.H. is co-owner and director of Radically Open Ltd, the RO DBT training and dissemination company.

RESUMO

BACKGROUND: Opioid use disorder is a chronic, debilitating, and costly disorder that has increased in prevalence in many countries, with an associated sharp rise in mortality. Maintenance opioid agonist therapy is the first-line treatment, but many patients do not stop using illicit or non-prescribed drugs concomitantly. We aimed to test the efficacy and cost-effectiveness of a personalised psychosocial intervention implemented with a toolkit of behaviour-change techniques as an adjunct to opioid agonist therapy. METHODS: We did a pragmatic, open-label, randomised controlled trial at a specialist UK National Health Service community addictions clinic in London, UK. Eligible patients were aged 18 years or older, met criteria for opioid or cocaine dependence, or both, in the past 12 months, and voluntarily sought continued oral maintenance opioid agonist therapy, which they had been prescribed for at least 6 weeks. All participants were treatment resistant (ie, had used illicit or non-prescribed opioids or cocaine on one or more days in the past 28 days at study screening, which was verified by positive urine drug screen). Participants were allocated (1:1) by a web-accessed randomisation sequence (stratified by opioid agonist medication, current cocaine use, and current rug use) to receive a personalised psychosocial intervention (comprising a flexible toolkit of psychological-change methods, including contingency management to reinforce abstinence, recovery activities, and clinic attendance) in addition to treatment as usual, or treatment as usual only (control group). The primary outcome was treatment response at 18 weeks, which was defined as abstinence from illicit and non-prescribed opioids and cocaine in the past 28 days, as measured with treatment outcomes profiles and urine drug screening. Taking a societal cost perspective, we did an evaluation of cost-effectiveness with a wide range of willingness-to-pay values for a unit improvement in the probability of treatment response. We also calculated quality-adjusted life-years (QALYs). Efficacy was analysed in a modified-intention-to-treat population, including all participants who were randomly allocated but excluding those who had previously completed the intervention. This trial is registered with ISRCTN, number ISRCTN69313751. The trial is completed. FINDINGS: Between June 7, 2013, and Dec 21, 2015, we randomly allocated 136 participants to the psychosocial intervention group and 137 to the control group. The trial database was locked on April 19, 2017. Three patients (one in the psychosocial intervention group and two in the control group) who were re-randomised in error were excluded from the analysis. 22 (16%) of 135 patients in the psychosocial intervention group had a treatment response, compared with nine (7%) of 135 in the control group (adjusted log odds 1·20 [95% CI 0·01-2·37]; p=0·048). The psychosocial intervention had a higher probability of being cost-effective than treatment as usual. There was a probability range of 47-87% for willingness-to-pay thresholds of £0-1000 for a unit improvement in the probability of treatment response. QALYs were higher in the psychosocial intervention group than in the control group (mean difference 0·048 [95% CI 0·016-0·080]; p=0·004) in adjusted analyses, with 60% and 67% probabilities of cost-effectiveness at the UK National Institute for Health and Care Excellence's willingness-to-pay thresholds of £20 000 and £30 000 per QALY, respectively. The number of adverse events was similar between groups, and no severe adverse events in either group were judged to be treatment related. One participant in the control group was hospitalised with drug-injection-related sepsis and died. INTERPRETATION: In maintenance opioid agonist therapy, an adjunctive personalised psychosocial intervention in addition to standard therapy was efficacious and cost-effective compared with standard therapy alone at helping treatment-resistant patients abstain from using illicit and non-prescribed opioids and cocaine.

RESUMO

BACKGROUND: People recovering from heroin addiction need better treatments than are currently offered. The chronic relapsing nature of drug dependence means that helping a patient to achieve abstinence is often difficult. Naltrexone blocks the effects of ingested heroin; however, evidence is conflicting regarding the best delivery method. OBJECTIVES: The primary purpose of the trial was to evaluate the clinical effectiveness and cost-effectiveness of extended-release naltrexone versus standard oral naltrexone versus relapse prevention therapy without medication for opioid use disorder (OUD). DESIGN: This was a 3-year, definitive, three-centre, three-arm, parallel group, placebo-controlled, double-blind, double-dummy, randomised controlled trial. SETTING: Two specialist NHS outpatient addiction clinics: one in London and one in Birmingham. PARTICIPANTS: Planned study sample - 300 adult patients with OUD who had completed detoxification. INTERVENTIONS: One iGen/Atral-Cipan Extended Release Naltrexone device (iGen/Atral-Cipan, Castanheira do Ribatejo, Portugal) (765 mg naltrexone or placebo) at day 0 of study week 1. Three weekly directly observed active or placebo oral naltrexone tablets (2 × 50 mg, Monday and Wednesday; 3 × 50 mg, Friday) at day 0 of study week 1 (for 4 weeks) and then an 8-week regimen of patient-administered dosing at the same dosing level. MAIN OUTCOME MEASURE: The primary outcome measure was the proportion of heroin-negative urine drug screen (UDS) results at the end of the 12-week post-randomisation time point. RESULTS: Six patients were recruited and randomised to receive study interventions. Two patients had no positive UDS samples for heroin during the 12-week treatment period, one patient had only one positive UDS sample and the remaining patients had two, six and eight positive UDS results for heroin. All patients had at least one missed clinic visit (range 1-14). CONCLUSIONS: Considerable problems were encountered with (1) the stipulated requirement of a validated 'detoxified' status prior to the initiation of the study naltrexone, (2) the requirement for a consent cooling-off period and (3) delays awaiting the surgical implant procedure. Major upheaval to the organisation and delivery of NHS community treatment services across England led to extremely poor levels of actual entry of patients into the trial. Research-vital clinical and procedural requirements were, therefore, more challenging to implement. The potential therapeutic value of the opioid antagonist naltrexone still needs clear investigation, including comparison of the established oral form with the new ultra-long-acting depot implant formulations (for which no licensed products exist in Europe). Despite the small number of study participants, some tentative conclusions can be reached, relevant to potential future work. The blinding of the active/placebo medications appeared to be good. Self-report was not sufficient to detect instances of heroin use. Self-report plus UDS information provided a fuller picture. Instances of lapsed heroin use were not necessarily followed by full relapse, and future work should consider the lapse-relapse relationship. The prison release setting also warrants special consideration. In future, investigators should consider seeking ethics approval for studies in which clinical procedures to accelerate the treatment process are permitted, even if outside orthodox clinical practice, if they address a clinical need at the time of challenge and clinical risk. In addition, it may be appropriate to seek exemption from the ordinary requirement of a cooling-off period after securing consent because it is often essential to initiate treatment promptly.
