Background and Aims: Alcohol use increases throughout adolescence. Emergency department (ED) attendance is an opportunity for alcohol screening and brief intervention (ASBI), which is effective for adults. This trial evaluated the effectiveness and cost-effectiveness of ASBI compared with screening alone (SA) in high-risk adolescents., Design, Setting and Participants: Multi-centre, three-group, single-blind, individually randomized trial with follow-ups after 6 and 12 months in 10 ED settings in England. From October 2014 to May 2015 we screened 3327 adolescents aged 14 to 18 years, of whom 756 (22.7%) scored at least 3 on the Alcohol Use Disorders Identification Test: consumption (AUDIT-C) and consented to participate in this trial. Mean age was 16.1 years; 50.2% were female and 84.9% were white., Interventions: Interventions were personalized feedback and brief advice (PFBA), personalized feedback plus electronic brief intervention (eBI) and SA., Measures: The primary outcome was the weekly alcohol consumed in standard UK units (8 g ethanol) at 12 months post-randomization, derived from extended AUDIT-C. Economic outcomes included quality of life and service use, from perspectives of both the National Health Service and personal social services (NHS&PSS) and society., Findings: At 12 months, mean weekly consumption was 2.99 [95% confidence interval (CI) = 2.38-3.70] standard units for the SA group, 3.56 (95% CI = 2.90, 4.32) for PFBA and 3.18 (95% CI = 2.50, 3.97) for eBI, showing no significant differences. The PFBA group consumed mean 0.57 (-0.36, 1.70) units more than SA; and eBIs consumed 0.19 (-0.71, 1.30) more. Bayes factors suggested lack of effectiveness explained non-significance. From the NHS&PSS perspective, economic analysis showed that PFBA and eBI were not cost-effective compared with SA: PFBA yielded incremental cost-effectiveness ratio of £6213 (-£736 843, £812 884), with the intervention having 54% probability of being cost-effective compared with SA at the £20 000 WTP threshold., Conclusions: In emergency departments in England, neither personalized feedback and brief advice nor personalized feedback plus electronic brief intervention showed evidence of being effective or cost-effective when compared with screening alone in reducing alcohol consumption among adolescents., (© 2022 The Authors.

Background: Individuals with low serum vitamin B-12 and high serum folate have higher plasma concentrations of methylmalonic acid (MMA). Whether folic acid (FA) causes an increase in MMA is not known., Objectives: We aimed to determine the impact of FA supplementation on plasma MMA concentration in people with low or marginal serum vitamin B-12., Methods: We conducted a multicenter double-blind placebo-controlled randomized trial of oral FA (5 mg/d for 12 wk) in middle-aged patients treated with antidepressant medication participating in the FoLATED (Folate Augmentation of Treatment-Evaluation for Depression) trial. Participants defined as having "low" serum vitamin B-12 (vitamin B-12 ≥150 and <220 ng/L) or "marginal" serum vitamin B-12 (vitamin B-12 ≥ 220 and <280 ng/L) were included. The primary outcome of this substudy was MMA at week 12. A mixed-effects linear regression was fitted and reported using the adjusted mean difference (aMD)., Results: A total of 177 participants were included (85 randomly assigned to placebo and 92 to FA); the mean ± SD age was 46.2 ± 11.8 y, and 112 (63.3%) were female. The MMA analysis included 135 participants and the aMD was -0.01 (95% CI: -0.06, 0.04; P = 0.71). Serum folate was measured on 166 participants and increased in the supplementation group; the aMD was 21.6 μg/L (95% CI: 8.13, 25.02 μg/L; P < 0.001). A total of 117 participants were assessed for RBC folate, which also increased in the supplementation group; the aMD was 461 μg/L (95% CI: 387, 535 μg/L; P < 0.001)., Conclusions: Supplementation of FA leads to an increase of serum and RBC folate, but does not change plasma MMA concentration in individuals with serum vitamin B-12 between 150 and 280 ng/L. We cannot exclude effects in older people or those with serum vitamin B-12 <150 ng/L. Previously reported associations may arise from effects of impaired vitamin B-12 status on folate metabolism.This trial was registered at www.isrctn.com as ISRCTN37558856., (© The Author(s) 2021.

Background: Individuals with depression often do not respond to medication or psychotherapy. Radically open dialectical behaviour therapy (RO DBT) is a new treatment targeting overcontrolled personality, common in refractory depression., Aims: To compare RO DBT plus treatment as usual (TAU) for refractory depression with TAU alone (trial registration: ISRCTN 85784627)., Method: RO DBT comprised 29 therapy sessions and 27 skills classes over 6 months. Our completed randomised trial evaluated RO DBT for refractory depression over 18 months in three British secondary care centres. Of 250 adult participants, we randomised 162 (65%) to RO DBT. The primary outcome was the Hamilton Rating Scale for Depression (HRSD), assessed masked and analysed by treatment allocated., Results: After 7 months, immediately following therapy, RO DBT had significantly reduced depressive symptoms by 5.40 points on the HRSD relative to TAU (95% CI 0.94-9.85). After 12 months (primary end-point), the difference of 2.15 points on the HRSD in favour of RO DBT was not significant (95% CI -2.28 to 6.59); nor was that of 1.69 points on the HRSD at 18 months (95% CI -2.84 to 6.22). Throughout RO DBT participants reported significantly better psychological flexibility and emotional coping than controls. However, they reported eight possible serious adverse reactions compared with none in the control group., Conclusions: The RO DBT group reported significantly lower HRSD scores than the control group after 7 months, but not thereafter. The imbalance in serious adverse reactions was probably because of the controls' limited opportunities to report these.

Objective: To estimate the effectiveness of standardised self-management kits for children with type 1 diabetes., Design: Pragmatic trial with randomisation ratio of two intervention: one control. Qualitative process evaluation., Setting: 11 diabetes clinics in England and Wales., Participants: Between February 2010 and August 2011, we validly randomised 308 children aged 6-18 years; 201 received the intervention., Intervention: We designed kits to empower children to achieve glycaemic control, notably by recording blood glucose and titrating insulin. The comparator was usual treatment. OUTCOME MEASURES AT 3 AND 6 MONTHS: Primary: Diabetes Pediatric Quality of Life Inventory (PedsQL). Secondary: HbA1c; General PedsQL; EQ-5D; healthcare resource use., Results: Of the five Diabetes PedsQL dimensions, Worry showed adjusted scores significantly favouring self-management kits at 3 months (mean child-reported difference =+5.87; Standard error[SE]=2.19; 95% confidence interval [CI]) from +1.57 to +10.18; p=0.008); but Treatment Adherence significantly favoured controls at 6 months (mean child-reported difference=-4.68; SE=1.74; 95%CI from -8.10 to -1.25; p=0.008). Intervention children reported significantly worse changes between 3 and 6 months on four of the five Diabetes PedsQL dimensions and on the total score (mean difference=-3.20; SE=1.33; 95% CI from -5.73 to -0.67; p=0.020). There was no evidence of change in HbA1c; only 18% of participants in each group achieved recommended levels at 6 months. No serious adverse reactions attributable to the intervention or its absence were reported.Use of kits was poor. Few children or parents associated blood glucose readings with better glycaemic control. The kits, costing £185, alienated many children and parents., Conclusions: Standardised kits showed no evidence of benefit, inhibited diabetes self-management and increased worry. Future research should study relationships between children and professionals, and seek new methods of helping children and parents to manage diabetes., Trial Registration Number: ISRCTN17551624., Competing Interests: Competing interests: Professor JWG has received payments from Pfizer, Bayer and Ipsen for lectures, development of educational presentations and travel/accommodation to attend scientific meetings and advisory board meetings. His employer (Cardiff University) has also received funding from Novo Nordisk to support the development of patient-support materials used in the Development and Evaluation of a Psychosocial Intervention for Children and Teenagers Experiencing Diabetes (DEPICTED) research study., (© Author(s) (or their employer(s)) 2020.

Objective: To explore patients' experience of receiving pain relief injection for suspected hip fracture from paramedics at the location of the injury., Design: Qualitative interviews within a feasibility trial about an alternative to routine prehospital pain management for patients with suspected hip fracture., Setting: Patients treated by paramedics in the catchment area of one emergency department in South Wales., Participants: Six patients and one carer of a patient who received fascia iliaca compartment block (FICB)., Intervention: FICB administered to patients with suspected hip fracture by trained paramedics. We randomly allocated eligible patients to FICB-a local anaesthetic injection directly into the hip region-or usual care-most commonly morphine-using audited scratch cards., Outcomes: Acceptability and experience of receiving FICB, assessed through interview data. We audio-recorded, with participants' consent, and conducted thematic analysis of interview transcripts. The analysis team comprised two researchers, one paramedic and one lay member., Results: Patients had little or no memory of being offered, consenting to or receiving FICB. They recalled the reassuring manner and high quality of care received. They accepted FICB without question. Partial or confused memory characterised experience of subsequent hospital care until surgery. They said their priorities when calling for emergency help were to receive effective care. After hospital treatment, they wanted to regain their health and mobility and resume the quality of life they experienced before their injury., Conclusions: This study did not raise any concerns about the acceptability of FICB administered at the scene of injury by paramedics to people with suspected hip fracture. It adds to existing evidence about patient and carer experience of on-scene care for people with suspected hip fracture. Further research is needed to assess safety, effectiveness and cost effectiveness of this health technology in a new setting., Trial Registration Number: ISRCTN60065373., (© Author(s) (or their employer(s)) 2019.

Objective: To estimate the effect of deprivation on the demand for calls to National Health Service Direct Wales (NHSDW) controlling for confounding factors., Design: Study of routine data on over 400 000 calls to NHSDW using multiple regression to analyse the logarithms of ward-specific call rates across Wales by characteristics of call, patient and ward, notably the Welsh Index of Multiple Deprivation., Setting: 810 electoral wards with average population of 3300, defined by 1998 administrative boundaries., Population: All calls to NHSDW between January 2002 and June 2004., Main Outcome Measures: We used ward populations as denominators to calculate the rates of three categories of calls: calls seeking advice, calls seeking information and all calls combined., Results: Confounding variables explained 31% of variation in advice call rates, but only 14% of variation in information call rates and in all call rates (all significant at 0.1% level). However, deprivation was only a statistically significant predictor of information call rates. The proportion of the ward population categorised as 'white' was a highly significant predictor of all three call rates. For advice calls and combined calls, rates decreased highly significantly with the proportion of those who called the service for themselves. Information call rates were higher on weekdays and highest on Mondays, while advice call rates were highest on Sundays., Conclusions: Deprivation had no consistent effect on demand for the service and the relationship needs further exploration. While our data may have underestimated the 'need' of deprived patients, they yield no evidence that policy-makers should seek to improve demand from those patients. However, we found differences in the way callers use advice and information calls. Previously unexplored variables that help to predict ward-specific call rates include: ethnicity, day of the week and whether patients made the calls themselves., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

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.

Background: In managing hip fracture, effective pain relief before admission to hospital is difficult without risking side effects. Although emergency departments routinely use fascia iliaca compartment block (FICB), there has been little evaluation of its use by paramedics before hospital admission. We aimed to assess whether a multi-centre randomised trial to evaluate FICB was feasible., Methods: Volunteer paramedics used scratchcards to allocate patients with hip fracture at random between FICB and pain relief as usual. Primary outcomes were mortality and quality of life. We also measured adverse events, costs, final diagnosis, length of stay in hospital, pain scores and quality of care and collected qualitative data about acceptability to patients in interviews, and paramedics in focus groups. We pre-specified criteria for deciding whether to progress to a fully powered trial based on the recruitment of paramedics and patients, delivery of FICB, retrieval of outcome data, safety, acceptability, and diagnostic accuracy of hip fracture., Results: We effectively met all progression criteria: we recruited 19 paramedics who randomly allocated 71 patients between trial arms between 28 June 2016 and 31 July 2017; 57 (31 experimental arm, 26 usual care arm, 80% overall) retrospectively consented to follow-up. Just over half (17/31) of experimental participants received FICB; all others had contraindications, including nine taking anticoagulants. Four of the 31 participants assigned FICB and six of the 26 assigned usual care died within 6 months of hospital admission. Serious adverse events were also similar: 3/35 experimental versus 4/36 in usual care. Paramedics' recognition of hip fracture had sensitivity of 49/64 (77%) with a positive predictive value of 46/57 (81%). We received quality of life questionnaires for 30 of 49 patients (61%) at 1 month and 12 of 17 (71%) at 6 months. Patient satisfaction was similar: experimental mean 3.4 ( n  = 20) versus 3.5 ( n  = 13) for usual care., Conclusions: RAPID met all progression criteria within reasonable limits. As equipoise remains, we plan to undertake a fully powered multi-centre trial to test clinical and cost effectiveness of paramedic-administered FICB at the scene of hip fracture., Trial Registration: ISRCTN 60065373 sought 5 November 2015., Competing Interests: Competing interestsIan Pallister is Director of Trauma Simulation Ltd., which produced the bespoke mannequin used in training.

Objectives: To explore paramedics' experience of delivering fascia iliaca compartment block ( FICB) to patients with suspected hip fracture at the scene of injury., Design: Focus groups within a randomised controlled trial., Setting: Paramedics based at ambulance stations in the catchment area of one Emergency Department in South Wales, recruited and trained in a feasibility study about an alternative to routine prehospital pain management for patients with suspected hip fracture., Participants: 11 paramedics., Intervention: Paramedic-administered FICB to patients with suspected hip fracture. We randomly allocated eligible patients to FICB, a local anaesthetic injection directly into the hip region-or usual care, most commonly morphine - using audited scratch cards., Outcomes: Paramedics' experiences of administering FICB gathered through thematic analysis of interview transcripts by two researchers, one paramedic and one lay member., Results: Respondents believed that FICB was a suitable intervention for paramedics to deliver. It aligned with routine practice and was within people's capabilities. They said it took up to 10 minutes longer than usual care to prepare and deliver, in part due to nervousness and unfamiliarity with a new procedure. They praised the training provided but said they were anxious about causing harm by injecting into the wrong location. Confidence increased after one paramedic team successfully treated a patient for local anaesthetic toxicity. Reported challenges related to the emergency context: patients often waited many hours for ambulance arrival; moving patients exacerbated their pain; family and neighbours were present as paramedics administered treatment., Conclusions: Paramedics are willing and able to administer FICB to patients with suspected hip fracture before ambulance transport to hospital. Feasibility study findings will inform further research., Trial Registration Number: ISRCTN60065373; Pre results., Competing Interests: Competing interests: IP is Director of Trauma Simulation, which produced the bespoke mannequin used in training.

Background: The value of qualitative methods within trials is widely recognised, but their full potential is not being realised. There are also issues with the visibility, recognition and reporting of qualitative methods in trials. To identify potential improvements in qualitative research within trials, we need to study trials that have included qualitative methods. We aimed to explore the frequency of reporting qualitative methods in registered trials, the types of trials using qualitative methods and where in the world these trials were conducted., Methods: We included registries if they were searchable using keywords and held summaries of trials rather than listing reports or publications. We searched the included registries from the first available record in 1999 to the end of 2016 for the term 'qualitative'. We included trials only if we could confirm that they used qualitative methods through documented use of qualitative data collection and analysis in the registry summary. We analysed registered trials reporting the use of qualitative methods by: year registered, the country responsible for overseeing governance of the trial and the type of trial intervention (categorised as surgical, medical device, behavioural, drug or other)., Results: We included three registries: ClinicalTrials.gov, the International Standard Randomised Controlled Trial Number Registry (ISRCTN) and the World Health Organisation International Clinical Trials Registry Platform (WHO ICTRP). A total of 615,311 trials appear in these three registries from 1999 until the end of 2016. Numbers differed across registries with the WHO ICTRP the largest (366,753 trials), ClinicalTrials.gov the second largest (233,277) and ISRCTN the smallest (15,301). Of these registered trials, we confirmed that 1492 (0.24%) reported using qualitative methods. The ISRCTN contributed the highest percentage of trials reported as using qualitative methods (3.4%); in contrast, ClinicalTrials.gov reported 0.3% and WHO ICTRP reported 0.03%. The number and percentage of trials reported to use qualitative methods increased over time from 0 (0.0%) in 1999 to 285 (0.38%) in 2016. Trials reported as using qualitative methods originated from 52 countries across the world. Most were in Western higher-income countries: 38% in the United Kingdom and 28% in the United States. Most registered trials reported as using qualitative methods evaluated behavioural (39%) or other interventions with many fewer trials evaluating drugs (5%), medical devices (5%) or surgical interventions (4%)., Conclusion: The reported use of qualitative methods in registered trials has increased over time and worldwide. They are reportedly more frequent in high-income countries and in trials of behavioural and other interventions. Trialists and other stakeholders need to recognise the benefits of using qualitative methods in surgical, device and drug trials, and trials conducted in poorer countries. Moreover, they should seriously consider using qualitative methods in these trials.

Objectives: To develop and undertake initial validation of a patient-reported outcome measure to assess health-related quality of life in patients with breast cancer-related upper limb lymphedema (ULL)., Study Design and Setting: We developed and validated the Upper Limb Lymphedema Quality of Life (ULLQoL) scale in two stages: devising the items and pretesting with patients and clinicians; longitudinal validation to test its psychometric properties-underlying dimensions, internal consistency, test-retest reliability, construct validity, and responsiveness. Patients with ULL were recruited from two outpatient clinics., Results: We derived the ULLQoL scale from a pool of 98 items generated by patients. After further consultation, we produced the draft ULLQoL scale. For validation, 103 patients with ULL completed the draft scale and two generic health measures: SF-36 and ED-5D-3L. Psychometric analysis identified two components, physical and emotional well-being, with good internal consistency and test-retest reliability. Significant correlations with SF-36, EQ-5D-3L, and percentage excess limb volume confirmed construct validity. The ULLQoL scale showed good responsiveness to change reported by lymphedema patients and moderate to large effect sizes., Conclusion: The 14-item ULLQoL scale is a robust ULL-specific measure that is feasible and valid to use in both the clinical and research settings., (Copyright © 2018 Elsevier Inc.

Objectives: Incisional hernias are common complications of midline abdominal closure. The 'Hughes Repair' combines a standard mass closure with a series of horizontal and two vertical mattress sutures within a single suture. There is evidence to suggest this technique is as effective as mesh repair for the operative management of incisional hernias; however, no trials have compared Hughes repair with standard mass closure for the prevention of incisional hernia formation. This paper aims to test the feasibility of running a randomised controlled trial of a comparison of abdominal wall closure methods following midline incisional surgery for colorectal cancer, in preparation to a definitive randomised controlled trial., Design and Setting: A feasibility trial (with 1:1 randomisation) conducted perioperatively during colorectal cancer surgery., Participants: Patients undergoing midline incisional surgery for resection of colorectal cancer., Interventions: Comparison of two suture techniques (Hughes repair or standard mass closure) for the closure of the midline abdominal wound following surgery for colorectal cancer., Primary and Secondary Outcomes: A 30-patient feasibility trial assessed recruitment, randomisation, deliverability and early safety of the surgical techniques used., Results: A total of 30 patients were randomised from 43 patients recruited and consented, over a 5-month period. 14 and 16 patients were randomised to arms A and B, respectively. There was one superficial surgical site infection (SSI) and two organ space SSIs reported in arm A, and two superficial SSIs and one complete wound dehiscence in arm B. There were no suspected unexpected serious adverse reactions reported in either arm. Independent data monitoring committee found no early safety concerns., Conclusions: The feasibility trial found no early safety concerns and demonstrated that the trial was acceptable to patients. Progression to the pilot and main phases of the trial has now commenced following approval by the independent data monitoring committee., Trial Registration Number: ISRCTN 25616490., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Study Objective: We aim to determine clinical and cost-effectiveness of a paramedic protocol for the care of older people who fall., Methods: We undertook a cluster randomized trial in 3 UK ambulance services between March 2011 and June 2012. We included patients aged 65 years or older after an emergency call for a fall, attended by paramedics based at trial stations. Intervention paramedics could refer the patient to a community-based falls service instead of transporting the patient to the emergency department. Control paramedics provided care as usual. The primary outcome was subsequent emergency contacts or death., Results: One hundred five paramedics based at 14 intervention stations attended 3,073 eligible patients; 110 paramedics based at 11 control stations attended 2,841 eligible patients. We analyzed primary outcomes for 2,391 intervention and 2,264 control patients. One third of patients made further emergency contacts or died within 1 month, and two thirds within 6 months, with no difference between groups. Subsequent 999 call rates within 6 months were lower in the intervention arm (0.0125 versus 0.0172; adjusted difference -0.0045; 95% confidence interval -0.0073 to -0.0017). Intervention paramedics referred 8% of patients (204/2,420) to falls services and left fewer patients at the scene without any ongoing care. Intervention patients reported higher satisfaction with interpersonal aspects of care. There were no other differences between groups. Mean intervention cost was $23 per patient, with no difference in overall resource use between groups at 1 or 6 months., Conclusion: A clinical protocol for paramedics reduced emergency ambulance calls for patients attended for a fall safely and at modest cost., (Copyright © 2017 American College of Emergency Physicians.

Background: The majority of residents in care homes in the United Kingdom are living with dementia or significant memory problems. Caring in this setting can be difficult and stressful for care staff who work long hours, have little opportunity for training, are poorly paid and yet subject to high expectation. This may affect their mental and physical wellbeing, cause high rates of staff turnover and absenteeism, and affect the quality of care they provide. The main objective of this survey was to explore the nature, characteristics and associations of stress in care home staff., Methods: Staff working in a stratified random sample of care homes within Wales completed measures covering: general health and wellbeing (SF-12); stress (Work Stress Inventory); job content (Karasek Job Content); approach to, and experience of, working with people living with dementia (Approaches to Dementia Questionnaire; and Experience of Working with Dementia Patients); and Productivity and Health Status (SPS-6). Multiple linear regressions explored the effects of home and staff characteristics on carers., Results: 212 staff from 72 care homes completed questionnaires. Staff from nursing homes experienced more work stress than those from residential homes (difference 0.30; 95% confidence interval (CI) from 0.10 to 0.51; P  < 0.01), and were more likely to report that their health reduced their ability to work (difference -4.77; CI -7.80 to -1.73; P  < 0.01). Psychological demands on nurses were higher than on other staff (difference = 1.57; CI 0.03 to 3.10; P  < 0.05). A positive approach to dementia was more evident in those trained in dementia care (difference 8.54; CI 2.31 to 14.76; P  < 0.01), and in staff working in local authority homes than in the private sector (difference 7.75; CI 2.56 to 12.94; P  < 0.01)., Conclusions: Our study highlights the importance of dementia training in care homes, with a particular need in the private sector. An effective intervention to reduce stress in health and social care staff is required, especially in nursing and larger care homes, and for nursing staff., Trial Registration: ISRCTN registry: ISRCTN80487202. Registered 24 July 2013.

Background: Emergency calls are frequently made to ambulance services for older people who have fallen, but ambulance crews often leave patients at the scene without any ongoing care. We evaluated a new clinical protocol which allowed paramedics to assess older people who had fallen and, if appropriate, refer them to community-based falls services., Objectives: To compare outcomes, processes and costs of care between intervention and control groups; and to understand factors which facilitate or hinder use., Design: Cluster randomised controlled trial., Participants: Participating paramedics at three ambulance services in England and Wales were based at stations randomised to intervention or control arms. Participants were aged 65 years and over, attended by a study paramedic for a fall-related emergency service call, and resident in the trial catchment areas., Interventions: Intervention paramedics received a clinical protocol with referral pathway, training and support to change practice. Control paramedics continued practice as normal., Outcomes: The primary outcome comprised subsequent emergency health-care contacts (emergency admissions, emergency department attendances, emergency service calls) or death at 1 month and 6 months. Secondary outcomes included pathway of care, ambulance service operational indicators, self-reported outcomes and costs of care. Those assessing outcomes remained blinded to group allocation., Results: Across sites, 3073 eligible patients attended by 105 paramedics from 14 ambulance stations were randomly allocated to the intervention group, and 2841 eligible patients attended by 110 paramedics from 11 stations were randomly allocated to the control group. After excluding dissenting and unmatched patients, 2391 intervention group patients and 2264 control group patients were included in primary outcome analyses. We did not find an effect on our overall primary outcome at 1 month or 6 months. However, further emergency service calls were reduced at both 1 month and 6 months; a smaller proportion of patients had made further emergency service calls at 1 month (18.5% vs. 21.8%) and the rate per patient-day at risk at 6 months was lower in the intervention group (0.013 vs. 0.017). Rate of conveyance to emergency department at index incident was similar between groups. Eight per cent of trial eligible patients in the intervention arm were referred to falls services by attending paramedics, compared with 1% in the control arm. The proportion of patients left at scene without further care was lower in the intervention group than in the control group (22.6% vs. 30.3%). We found no differences in duration of episode of care or job cycle. No adverse events were reported. Mean cost of the intervention was £17.30 per patient. There were no significant differences in mean resource utilisation, utilities at 1 month or 6 months or quality-adjusted life-years. In total, 58 patients, 25 paramedics and 31 stakeholders participated in focus groups or interviews. Patients were very satisfied with assessments carried out by paramedics. Paramedics reported that the intervention had increased their confidence to leave patients at home, but barriers to referral included patients' social situations and autonomy., Conclusions: Findings indicate that this new pathway may be introduced by ambulance services at modest cost, without risk of harm and with some reductions in further emergency calls. However, we did not find evidence of improved health outcomes or reductions in overall NHS emergency workload. Further research is necessary to understand issues in implementation, the costs and benefits of e-trials and the performance of the modified Falls Efficacy Scale., Trial Registration: Current Controlled Trials ISRCTN60481756 and PROSPERO CRD42013006418., Funding: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment ; Vol. 21, No. 13.

Background: Adequate pain relief at the point of injury and during transport to hospital is a major challenge in all acute traumas, especially for those with hip fractures, whose injuries are difficult to immobilise and whose long-term outcomes may be adversely affected by administration of opiate analgesics. Fascia iliaca compartment block (FICB) is a procedure routinely undertaken by doctors and nurses in the emergency department for patients with hip fracture but not yet evaluated for use by paramedics at the scene of emergency calls. In this feasibility study, we aim to test whether FICB administered by paramedics at the scene of participants' hip fractures is feasible, safe and acceptable. This will enable us to decide whether to proceed to a fully powered, multi-centre pragmatic randomised trial to evaluate whether the procedure is effective for patients and worthwhile for the NHS., Methods/design: In this study, we propose to recruit ten paramedics in an urban area of South Wales. We will train them to carry out FICB when they attend patients with hip fracture. We will randomly allocate eligible patients to FICB or usual care using audited scratch cards. We will follow up participants to assess measurability of key outcomes including quality of life, pain scores, adverse events, length of stay in hospital, acceptability to patients and compliance of paramedics. We will assess whether the findings meet specified feasibility criteria and, if so, plan a full trial., Discussion: This study will enable us to recommend whether to undertake a definitive trial of FICB by paramedics for hip fracture., Trial Registration: ISRCTN60065373.

Background: Trials increasingly experience problems in recruiting participants. Understanding the causes of poor recruitment is critical to developing solutions. We interviewed people who had declined a trial of an innovative psychological therapy for depression (REFRAMED) about their response to the trial invitation, in order to understand their decision and identify ways to improve recruitment., Methods: Of 214 people who declined the trial, 35 (16 %) gave permission to be contacted about a qualitative study to explore their decision. Analysis of transcripts of semi-structured interviews was informed by grounded theory., Results: We interviewed 20 informants: 14 women and six men, aged 18 to 77 years. Many interviewees had prior experience of research participation and positive views of the trial. Interviewees' decision making resembled a four-stage sequential process; in each stage they either decided not to participate in the trial or progressed to the next stage. In stage 1, interviewees assessed the invitation in the context of their experiences and attitudes; we term those who opted out at this stage 'prior decliners' as they had an established position of declining trials. In stage 2, interviewees assessed their own eligibility; those who judged themselves ineligible and opted out at this stage are termed 'self-excluders'. In stage 3, interviewees assessed their need for the trial therapy and potential to benefit; we term those who decided they did not need the trial therapy and opted out at this stage 'treatment decliners'. In stage 4, interviewees deliberated the benefits and costs of trial participation; those who opted out after judging that disadvantages outweighed advantages are termed 'trial decliners'. Across all stages, most individuals declined because they judged themselves ineligible or not in need of the trial therapy. While 'prior decliners' are unlikely to respond to any trial recruitment initiative, the factors leading others to decline are amenable to amelioration as they do not arise from a rejection of trials or a personal stance., Conclusions: To improve recruitment in similar trials, the most successful interventions are likely to address patients' assessments of their eligibility and their potential to benefit from the trial treatment, rather than reducing trial burden., Trial Registration: International Standard Randomised Controlled Trial Number: ISRCTN85784627 .

Objectives: To develop a tool for the accurate reporting and aggregation of findings from each of the multiple methods used in a complex evaluation in an unbiased way., Study Design and Setting: We developed a Method for Aggregating The Reporting of Interventions in Complex Studies (MATRICS) within a gastroenterology study [Evaluating New Innovations in (the delivery and organisation of) Gastrointestinal (GI) endoscopy services by the NHS Modernisation Agency (ENIGMA)]. We subsequently tested it on a different gastroenterology trial [Multi-Institutional Nurse Endoscopy Trial (MINuET)]. We created three layers to define the effects, methods, and findings from ENIGMA. We assigned numbers to each effect in layer 1 and letters to each method in layer 2. We used an alphanumeric code based on layers 1 and 2 to every finding in layer 3 to link the aims, methods, and findings. We illustrated analogous findings by assigning more than one alphanumeric code to a finding. We also showed that more than one effect or method could report the same finding. We presented contradictory findings by listing them in adjacent rows of the MATRICS., Results: MATRICS was useful for the effective synthesis and presentation of findings of the multiple methods from ENIGMA. We subsequently successfully tested it by applying it to the MINuET trial., Conclusion: MATRICS is effective for synthesizing the findings of complex, multiple-method studies., (Crown Copyright © 2016.

Background and Study Aims: Patient satisfaction is a key indicator of the quality of gastrointestinal (GI) endoscopy. The aim of this study was to develop and validate a specific patient satisfaction questionnaire for patients undergoing GI endoscopy--the Gastrointestinal Endoscopy Satisfaction Questionnaire (GESQ)., Patients and Methods: We developed and validated the GESQ within the context of a national multi-institution nurse endoscopy trial, based in secondary care, in three stages: (1) item generation with a panel of patients and professionals following a detailed literature review to identify the most relevant items from existing scales; (2) development and piloting of a draft questionnaire on a sample of patients referred for GI endoscopy; and (3) testing of the questionnaire within a large multicenter pragmatic randomized trial. We undertook psychometric analysis of the questionnaire to identify the underlying dimensions and assessed the questionnaire for reliability and validity., Results: The final version of the GESQ contains 21 items. Principal components analysis revealed four subscales with high internal consistency: skills and hospital (seven items; Cronbach's alpha 0.83), pain and discomfort during and after endoscopy (four items; Cronbach's alpha 0.84), information before endoscopy (five items; Cronbach's alpha 0.80), and information after endoscopy (five items; Cronbach's alpha 0.76)., Conclusions: The four identified subscales are clinically relevant and correspond to domains of patient satisfaction identified in previous studies. Our development and validation of the GESQ confirmed that it is a valid, reliable, interpretable, and acceptable tool to measure satisfaction in patients who have undergone a GI endoscopy., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objectives: To develop and validate a gastrointestinal (GI) symptom rating questionnaire for patients with luminal GI symptoms including where no diagnosis has been made., Study Design and Setting: We developed and validated the Gastrointestinal Symptom Rating Questionnaire (GSRQ) in three stages: (1) item generation to identify the relevant items for scale inclusion; (2) development and piloting on patients with a known GI disorder; and (3) testing in a sample of trial patients. We examined the underlying dimensions of the scale, internal consistency, validity, reproducibility, and responsiveness., Results: We identified four interpretable factors on the GSRQ. The GSRQ had good internal consistency (corrected item-subscale correlations between 0.4 and 0.8) and Cronbach's alpha greater than 0.7 for each subscale. Construct validity was demonstrated by modest but significant correlations with the Short Form 36 and the EQ5D index value. We demonstrated good reproducibility with intraclass correlations for test-retest scores between 0.71 and 0.77, and significant responsiveness ratios for all subscales in patients who had improved, and in two of the subscales in patients who had deteriorated., Conclusion: The GSRQ could be a useful tool to monitor quality of life in various luminal GI conditions and where a formal diagnosis has not been made., (Copyright © 2015 Elsevier Inc.

It has been suggested that giving cell-salvaged blood through a leucocyte depletion filter can cause hypotension due to bradykinin released when factor XII and platelets are activated by the negatively charged surface of the filter. We measured the concentration of bradykinin and cysteinyl leukotrienes in cell-salvaged blood sampled before and after passage through a negatively charged leucodepletion filter in 24 consecutive patients with gynaecological or bowel cancer undergoing elective surgery with cell salvage. In no case was an increase in bradykinin concentration observed after passage through the filter; in 23 patients the post-filtration bradykinin concentration was zero (p = 0.007). The change in the concentration of cysteinyl leukotrienes detected during passage across the filter was not statistically significant (p = 0.1). Our findings do not support the suggestion that either bradykinin or cysteinyl leukotrienes are generated in cell-salvaged blood during passage through leucodepletion filters., (© 2015 The Association of Anaesthetists of Great Britain and Ireland.)

Background: Group cognitive stimulation therapy programmes can benefit cognition and quality of life for people with dementia. Evidence for home-based, carer-led cognitive stimulation interventions is limited., Objectives: To evaluate the clinical effectiveness and cost-effectiveness of carer-delivered individual cognitive stimulation therapy (iCST) for people with dementia and their family carers, compared with treatment as usual (TAU)., Design: A multicentre, single-blind, randomised controlled trial assessing clinical effectiveness and cost-effectiveness. Assessments were at baseline, 13 weeks and 26 weeks (primary end point)., Setting: Participants were recruited through Memory Clinics and Community Mental Health Teams for older people., Participants: A total of 356 caregiving dyads were recruited and 273 completed the trial., Intervention: iCST consisted of structured cognitive stimulation sessions for people with dementia, completed up to three times weekly over 25 weeks. Family carers were supported to deliver the sessions at home., Main Outcome Measures: Primary outcomes for the person with dementia were cognition and quality of life. Secondary outcomes included behavioural and psychological symptoms, activities of daily living, depressive symptoms and relationship quality. The primary outcome for the family carers was mental/physical health (Short Form questionnaire-12 items). Health-related quality of life (European Quality of Life-5 Dimensions), mood symptoms, resilience and relationship quality comprised the secondary outcomes. Costs were estimated from health and social care and societal perspectives., Results: There were no differences in any of the primary outcomes for people with dementia between intervention and TAU [cognition: mean difference -0.55, 95% confidence interval (CI) -2.00 to 0.90; p-value = 0.45; self-reported quality of life: mean difference -0.02, 95% CI -1.22 to 0.82; p-value = 0.97 at the 6-month follow-up]. iCST did not improve mental/physical health for carers. People with dementia in the iCST group experienced better relationship quality with their carer, but there was no evidence that iCST improved their activities of daily living, depression or behavioural and psychological symptoms. iCST seemed to improve health-related quality of life for carers but did not benefit carers' resilience or their relationship quality with their relative. Carers conducting more sessions had fewer depressive symptoms. Qualitative data suggested that people with dementia and their carers experienced better communication owing to iCST. Adjusted mean costs were not significantly different between the groups. From the societal perspective, both health gains and cost savings were observed., Conclusions: iCST did not improve cognition or quality of life for people with dementia, or carers' physical and mental health. Costs of the intervention were offset by some reductions in social care and other services. Although there was some evidence of improvement in terms of the caregiving relationship and carers' health-related quality of life, iCST does not appear to deliver clinical benefits for cognition and quality of life for people with dementia. Most people received fewer than the recommended number of iCST sessions. Further research is needed to ascertain the clinical effectiveness of carer-led cognitive stimulation interventions for people with dementia., Trial Registration: Current Controlled Trials ISRCTN65945963., Funding: This project was funded by the National Institute of Health Research (NIHR) Health Technology Assessment (HTA) programme and will be published in full in Health Technology Assessment; Vol. 19, No. 64.

Introduction: Only 30-40% of depressed patients treated with medication achieve full remission. Studies that change medication or augment it by psychotherapy achieve only limited benefits, in part because current treatments are not designed for chronic and complex patients. Previous trials have excluded high-risk patients and those with comorbid personality disorder. Radically Open Dialectical Behaviour Therapy (RO-DBT) is a novel, transdiagnostic treatment for disorders of emotional over-control. The REFRAMED trial aims to evaluate the effectiveness and cost-effectiveness of RO-DBT for patients with treatment-resistant depression., Methods and Analysis: REFRAMED is a multicentre randomised controlled trial, comparing 7 months of individual and group RO-DBT treatment with treatment as usual (TAU). Our primary outcome measure is depressive symptoms 12 months after randomisation. We shall estimate the cost-effectiveness of RO-DBT by cost per quality-adjusted life year. Causal analyses will explore the mechanisms by which RO-DBT is effective., Ethics and Dissemination: The National Research Ethics Service (NRES) Committee South Central - Southampton A first granted ethical approval on 20 June 2011, reference number 11/SC/0146., Trial Registration Number: ISRCTN85784627., (Published by the BMJ Publishing Group Limited.

Objective: To develop, validate and apply a generic clinical severity index applicable to all adult patients with inflammatory bowel disease (IBD)., Design: A review of the literature and an expert focus group consultation were carried out in order to draw out relevant items from existing literature. The new index was called the IBD Index (IBDEX). Standard psychometric analysis was carried out. The construct validity was assessed against biochemical markers, clinical and endoscopic indices. The new index was completed again within 6 weeks to check responsiveness and reproducibility., Results: IBDEX was used to assess 255 adult patients with IBD (125 with Crohn's disease and 130 with ulcerative colitis), and 64 patients were re-evaluated within 6 weeks. It had good internal consistency (Cronbach's α=0.79) and correlated very well with the Harvey Bradshaw Index (r=0.94), the Simple Clinical Colitis Activity Index (r=0.92), the Mayo Clinic Index (r=0.87) and the Simple Endoscopic Score (r=0.76), all with p values <0.05. IBDEX had a moderate but positive correlation with C reactive protein (r=0.51) and erythrocyte sedimentation rate (r=0.36) p values both <0.05. The test-retest reliability was good (intraclass correlation coefficient 0.97) and responsiveness ratio was 2.27., Conclusions: IBDEX is the first properly validated Clinical Disease Severity Index in IBD. Our results showed that it is valid, reliable and reproducible and has the potential to be used in clinical practice.

Background: Morton's neuroma is a common foot condition affecting health-related quality of life. Though its management frequently includes steroid injections, evidence of cost-effectiveness is sparse. So, we aimed to evaluate whether steroid injection is cost-effective in treating Morton's neuroma compared with anaesthetic injection alone., Methods: We undertook incremental cost-effectiveness and cost-utility analyses from the perspective of the National Health Service, alongside a patient-blinded pragmatic randomised trial in hospital-based orthopaedic outpatient clinics in Edinburgh, UK. Of the original randomised sample of 131 participants with Morton's neuroma (including 67 controls), economic analysis focused on 109 (including 55 controls). Both groups received injections guided by ultrasound. We estimated the incremental cost per point improvement in the area under the curve of the Foot Health Thermometer (FHT-AUC) until three months after injection. We also conducted cost-utility analyses using European Quality of life-5 Dimensions-3 Levels (EQ-5D-3L), enhanced by the Foot Health Thermometer (FHT), to estimate utility and thus quality-adjusted life years (QALYs)., Results: The unit cost of an ultrasound-guided steroid injection was £149. Over the three months of follow-up, the mean cost of National Health Service resources was £280 for intervention participants and £202 for control participants - a difference of £79 [bootstrapped 95% confidence interval (CI): £18 to £152]. The corresponding estimated incremental cost-effectiveness ratio was £32 per point improvement in the FHT-AUC (bootstrapped 95% CI: £7 to £100). If decision makers value improvement of one point at £100 (the upper limit of this CI), there is 97.5% probability that steroid injection is cost-effective. As EQ-5D-3L seems unresponsive to changes in foot health, we based secondary cost-utility analysis on the FHT-enhanced EQ-5D. This estimated the corresponding incremental cost-effectiveness ratio as £6,400 per QALY. Over the recommended UK threshold, ranging from £20,000 to £30,000 per QALY, there is 80%-85% probability that steroid injection is cost-effective., Conclusions: Steroid injections are effective and cost-effective in relieving foot pain measured by the FHT for three months. However, cost-utility analysis was initially inconclusive because the EQ-5D-3L is less responsive than the FHT to changes in foot health. By using the FHT to enhance the EQ-5D, we inferred that injections yield good value in cost per QALY., Trial Registration: Current Controlled Trials ISRCTN13668166.

Background and Aims: Most of the disease-specific quality of life (QoL) measures for inflammatory bowel disease (IBD) are lengthy and time consuming. None have been established for routine use in clinical practice. We designed this study to develop a short QoL measure in IBD., Methods: A 32-item questionnaire, the Crohn's and ulcerative colitis questionnaire (CUCQ)-32 was developed by reviewing the literature of the previously validated questionnaires and by consultation with patients and experts. Construct validity was carried out using the Short Form 12 and the EuroQol 5 dimensions questionnaires and two disease severity measures (the Simple Clinical Colitis Activity Index and the Harvey-Bradshaw Index). Test-retest analysis was done by asking patients to complete the CUCQ questionnaire twice within a period of two weeks., Results: Data were obtained from 205 patients with IBD who completed the CUCQ-32. Psychometric analysis showed that Cronbach's α was 0.88, item-total correlations were good, and there were no ceiling or flooring effects. Stepwise regression identified eight items that accounted for >95% of the variance in the CUCQ-32. The resulting CUCQ-8 demonstrated good internal consistency (Cronbach's α = 0.84), had good reproducibility (intraclass correlation coefficient = 0.94), was well correlated with the EuroQol 5 dimensions questionnaire (r = 0.58) and the Short Form-12 (r = 0.65 for physical component and r = 0.63 for mental component), and was responsive to change (responsiveness ratio was 0.64, p-value < 0.05)., Conclusions: CUCQ-8 is a short questionnaire that has the potential to be an efficient tool for assessing the QoL of all patients with IBD in clinical practice., (Copyright © 2014 European Crohn’s and Colitis Organisation (ECCO).

Objective: To evaluate effectiveness, safety and cost-effectiveness of Computerised Clinical Decision Support (CCDS) for paramedics attending older people who fall., Design: Cluster trial randomised by paramedic; modelling., Setting: 13 ambulance stations in two UK emergency ambulance services., Participants: 42 of 409 eligible paramedics, who attended 779 older patients for a reported fall., Interventions: Intervention paramedics received CCDS on Tablet computers to guide patient care. Control paramedics provided care as usual. One service had already installed electronic data capture., Main Outcome Measures: Effectiveness: patients referred to falls service, patient reported quality of life and satisfaction, processes of care., Safety: Further emergency contacts or death within one month., Cost-Effectiveness: Costs and quality of life. We used findings from published Community Falls Prevention Trial to model cost-effectiveness., Results: 17 intervention paramedics used CCDS for 54 (12.4%) of 436 participants. They referred 42 (9.6%) to falls services, compared with 17 (5.0%) of 343 participants seen by 19 control paramedics [Odds ratio (OR) 2.04, 95% CI 1.12 to 3.72]. No adverse events were related to the intervention. Non-significant differences between groups included: subsequent emergency contacts (34.6% versus 29.1%; OR 1.27, 95% CI 0.93 to 1.72); quality of life (mean SF12 differences: MCS -0.74, 95% CI -2.83 to +1.28; PCS -0.13, 95% CI -1.65 to +1.39) and non-conveyance (42.0% versus 36.7%; OR 1.13, 95% CI 0.84 to 1.52). However ambulance job cycle time was 8.9 minutes longer for intervention patients (95% CI 2.3 to 15.3). Average net cost of implementing CCDS was £208 per patient with existing electronic data capture, and £308 without. Modelling estimated cost per quality-adjusted life-year at £15,000 with existing electronic data capture; and £22,200 without., Conclusions: Intervention paramedics referred twice as many participants to falls services with no difference in safety. CCDS is potentially cost-effective, especially with existing electronic data capture., Trial Registration: ISRCTN Register ISRCTN10538608.

Objective: To assess the clinical effect of medication monitoring using the West Wales Adverse Drug Reaction (ADR) Profile for Respiratory Medicine., Design: Single-site parallel-arm pragmatic trial using stratified randomisation., Setting: Nurse-led respiratory outpatient clinic in general hospital in South Wales., Participants: 54 patients with chronic respiratory disease receiving bronchodilators, corticosteroids or leukotriene receptor antagonists., Intervention: Following initial observation of usual nursing care, we allocated participants at random to receive at follow up: either the West Wales ADR Profile for Respiratory Medicine in addition to usual care ('intervention arm' with 26 participants); or usual care alone ('control arm' with 28 participants)., Main Outcome Measures: Problems reported and actions taken., Results: We followed up all randomised participants, and analysed data in accordance with treatment allocated. The increase in numbers of problems per participant identified at follow up was significantly higher in the intervention arm, where the median increase was 20.5 [inter-quartile range (IQR) 13-26], while that in the control arm was -1 [-3 to +2] [Mann-Whitney U test: z = 6.28, p<0.001]. The increase in numbers of actions per participant taken at follow up was also significantly higher in the intervention arm, where the median increase was 2.5 [1]-[4] while that in the control arm was 0 [-1.75 to +1] [Mann-Whitney U test: z = 4.40, p<0.001]., Conclusion: When added to usual nursing care, the West Wales ADR Profile identified more problems and prompted more nursing actions. Our ADR Profile warrants further investigation as a strategy to optimise medication management., Trial Registration: Controlled-trials.com ISRCTN10386209.

Objective: We compared mindfulness-based cognitive therapy (MBCT) with both cognitive psychological education (CPE) and treatment as usual (TAU) in preventing relapse to major depressive disorder (MDD) in people currently in remission following at least 3 previous episodes., Method: A randomized controlled trial in which 274 participants were allocated in the ratio 2:2:1 to MBCT plus TAU, CPE plus TAU, and TAU alone, and data were analyzed for the 255 (93%; MBCT = 99, CPE = 103, TAU = 53) retained to follow-up. MBCT was delivered in accordance with its published manual, modified to address suicidal cognitions; CPE was modeled on MBCT, but without training in meditation. Both treatments were delivered through 8 weekly classes., Results: Allocated treatment had no significant effect on risk of relapse to MDD over 12 months follow-up, hazard ratio for MBCT vs. CPE = 0.88, 95% CI [0.58, 1.35]; for MBCT vs. TAU = 0.69, 95% CI [0.42, 1.12]. However, severity of childhood trauma affected relapse, hazard ratio for increase of 1 standard deviation = 1.26 (95% CI [1.05, 1.50]), and significantly interacted with allocated treatment. Among participants above median severity, the hazard ratio was 0.61, 95% CI [0.34, 1.09], for MBCT vs. CPE, and 0.43, 95% CI [0.22, 0.87], for MBCT vs. TAU. For those below median severity, there were no such differences between treatment groups., Conclusion: MBCT provided significant protection against relapse for participants with increased vulnerability due to history of childhood trauma, but showed no significant advantage in comparison to an active control treatment and usual care over the whole group of patients with recurrent depression.

Background: Complex clinical interventions are increasingly subject to evaluation by randomised trial linked to economic evaluation. However evaluations of policy initiatives tend to eschew experimental designs in favour of interpretative perspectives which rarely allow the economic evaluation methods used in clinical trials. As evidence of the cost effectiveness of such initiatives is critical in informing policy, it is important to explore whether conventional economic evaluation methods apply to experimental evaluations of policy initiatives., Methods: We used mixed methods based on a quasi-experimental design to evaluate a policy initiative whose aim was to expedite the modernisation of gastroenterology endoscopy services in England. We compared 10 sites which had received funding and support to modernise their endoscopy services with 10 controls. We collected data from five waves of patients undergoing endoscopy. The economic component of the study compared sites by levels of investment in modernisation and patients' use of health service resources, time off work and health related quality of life., Results: We found no statistically significant difference between intervention and control sites in investment in modernisation or any patient outcome including health., Conclusions: This study highlights difficulties in applying the rigour of a randomised trial and associated technique of economic evaluation to a policy initiative. It nevertheless demonstrates the feasibility of using this approach although further work is needed to demonstrate its generalisability in other applications. The present application shows that the small incentives offered to intervention sites did not enhance modernisation of gastroenterology endoscopy services or improve patient outcomes.

Objectives: People with dementia are susceptible to adverse effects of medicines. However, they are not always closely monitored. We explored (1) feasibility and (2) clinical impact of nurse-led medication monitoring., Design: Feasibility "before-and-after" intervention study., Setting: Three care homes in Wales., Participants: Eleven service users diagnosed with dementia, taking at least one antipsychotic, antidepressant, or antiepileptic medicine., Intervention: West Wales Adverse Drug Reaction (ADR) Profile for Mental Health Medicines., Outcome Measures: (1) Feasibility: recruitment, retention, and implementation. (2) Clinical impact: previously undocumented problems identified and ameliorated, as recorded in participants' records before and after introduction of the profile, and one month later., Results: Nurses recruited and retained 11 of 29 eligible service users. The profile took 20-25 minutes to implement, caused no harm, and supplemented usual care. Initially, the profile identified previously undocumented problems for all participants (mean 12.7 (SD 4.7)). One month later, some problems had been ameliorated (mean 4.9 (3.6)). Clinical gains included new prescriptions to manage pain (2 participants), psoriasis (1), Parkinsonian symptoms (1), rash (1), dose reduction of benzodiazepines (1), new care plans for oral hygiene, skin problems, and constipation., Conclusions: Participants benefited from structured nurse-led medication monitoring. Clinical trials of our ADR Profile are feasible and necessary.

Background and Purpose: U.K ambulance services assess patients with suspected stroke using the Face Arm Speech Test (FAST). The Recognition Of Stroke In the Emergency Room (ROSIER) tool has been shown superior to the FAST in identifying strokes in emergency departments but has not previously been tested in the ambulance setting. We investigated whether ROSIER use by ambulance clinicians can improve stroke recognition., Methods: Ambulance clinicians used the ROSIER in place of the FAST to assess patients with suspected stroke. As the ROSIER includes all FAST elements, we calculated a FAST score from the ROSIER to enable comparisons between the two tools. Ambulance clinicians' provisional stroke diagnoses using the ROSIER and calculated FAST were compared with stroke consultants' diagnosis. We used stepwise logistic regression to compare the contribution of individual ROSIER and FAST items and patient demographics to the prediction of consultants' diagnoses., Results: Sixty-four percent of strokes and 78% of nonstrokes identified by ambulance clinicians using the ROSIER were subsequently confirmed by a stroke consultant. There was no difference in the proportion of strokes correctly detected by the ROSIER or FAST with both displaying excellent levels of sensitivity. The ROSIER detected marginally more nonstroke cases than the FAST, but both demonstrated poor specificity. Facial weakness, arm weakness, seizure activity, age, and sex predicted consultants' diagnosis of stroke., Conclusions: The ROSIER was not better than the FAST for prehospital recognition of stroke. A revised version of the FAST incorporating assessment of seizure activity may improve stroke identification and decision making by ambulance clinicians.

Background: An ageing population increases demand on health and social care. New approaches are needed to shift care from hospital to community and general practice. A predictive risk stratification tool (Prism) has been developed for general practice that estimates risk of an emergency hospital admission in the following year. We present a protocol for the evaluation of Prism., Methods/design: We will undertake a mixed methods progressive cluster-randomised trial. Practices begin as controls, delivering usual care without Prism. Practices will receive Prism and training randomly, and thereafter be able to use Prism with clinical and technical support. We will compare costs, processes of care, satisfaction and patient outcomes at baseline, 6 and 18 months, using routine data and postal questionnaires. We will assess technical performance by comparing predicted against actual emergency admissions. Focus groups and interviews will be undertaken to understand how Prism is perceived and adopted by practitioners and policy makers. We will model data using generalised linear models and survival analysis techniques to determine whether any differences exist between intervention and control groups. We will take account of covariates and explanatory factors. In the economic evaluation we will carry out a cost-effectiveness analysis to examine incremental cost per emergency admission to hospital avoided and will examine costs versus changes in primary and secondary outcomes in a cost-consequence analysis. We will also examine changes in quality of life of patients across the risk spectrum. We will record and transcribe focus groups and interviews and analyse them thematically. We have received full ethical and R and D approvals for the study and Information Governance Review Panel (IGRP) permission for the use of routine data. We will comply with the CONSORT guidelines and will disseminate the findings at national and international conferences and in peer-reviewed journals., Discussion: The proposed study will provide information on costs and effects of Prism; how it is used in practice, barriers and facilitators to its implementation; and its perceived value in supporting the management of patients with and at risk of developing chronic conditions., Trial Registration: Controlled Clinical Trials ISRCTN no.

Background: Endoscopic ultrasonography is recommended for staging gastro-oesophageal cancers, but has never been evaluated., Objective: COGNATE (Cancer of Oesophagus or Gastricus - New Assessment of Technology of Endosonography) therefore aimed to evaluate whether adding 'endoscopic ultrasound' (EUS) to the usual staging algorithm changes treatment, improves (quality-adjusted) survival, and uses resources cost-effectively., Design: Pragmatic parallel-group trial. Patients with gastro-oesophageal cancer received standard staging algorithms. Multidisciplinary teams chose provisional management plans from endoscopic mucosal resection, immediate surgery, surgery after chemotherapy, or chemotherapy and radiotherapy. We used dynamic randomisation to allocate consenting patients remotely by telephone in equal proportions between EUS and not. Thereafter we recorded changes in management plan, use of health-care resources, and three aspects of participant-reported quality of life: generic [measured by European Quality of Life - 5 Dimensions (EQ-5D)], cancer related [Functional Assessment of Cancer Therapy - General scale (FACT-G)] and condition-specific [FACT - Additional Concerns scale (FACT-AC)]. We followed participants regularly until death or the end of the trial - for between 1 and 4.5 years. We devised a quality assurance programme to maintain standards of endosonographic reporting., Setting: Eight British hospitals, of which two - one Scottish teaching hospital and one English district general hospital - contributed 80% of participants; we combined the other six for analysis., Participants: Patients were eligible if they had a diagnosis of gastro-oesophageal cancer, had not started treatment, were free of metastatic disease, were fit for surgery (even if not planned) and had American Society of Anesthesiologists and World Health Organization grades of less than 3., Interventions: Intervention group: standard staging algorithm plus EUS; control group: standard staging algorithm., Main Outcome Measures: Primary: quality-adjusted survival. Secondary: survival; health-related quality of life (EQ-5D, FACT-G and FACT-AC scales); changes in management plan; and complete resection rate. Although blinding participants was neither possible nor desirable, those responsible for analysis remained blind until the Trial Steering Committee had reviewed the definitive analysis., Results: We randomised 223 patients, of whom 213 yielded enough data for primary analysis. EUS improved survival adjusted for generic quality of life with a hazard ratio of 0.705 [95% confidence interval (CI) 0.499 to 0.995], and crude survival with a hazard ratio of 0.706 (95% CI 0.501 to 0.996). The benefits of EUS were significantly greater for those with poor initial quality of life, but did not differ between centres. EUS reduced net use of health-care resources by £2860 (95% 'bootstrapped' CI from -£2200 to £8000). Combining benefits and savings shows that EUS is likely to be cost-effective, with 96% probability of achieving the National Institute for Health and Care Excellence criterion of costing of < £20,000 to gain a QALY. There were no serious adverse reactions attributable to EUS. EUS enhanced the management plan for many participants, increased the proportion of tumours completely resected from 80% (44 out of 55) to 91% (48 out of 53), and improved the survival of those who changed plan; although underpinning the significant differences in outcome, none of these process differences was itself significant., Conclusion: Endoscopic ultrasound significantly improves (quality-adjusted) survival, has the potential to reduce health-care resource use (not statistically significant) and is probably cost-effective (with 96% probability).

Background: The vulnerability of clinical trials to volunteer bias is under-reported. Volunteer bias is systematic error due to differences between those who choose to participate in studies and those who do not., Methods and Results: This paper extends the applications of the concept of volunteer bias by using data from a trial of probiotic supplementation for childhood atopy in healthy dyads to explore 1) differences between a) trial participants and aggregated data from publicly available databases b) participants and non-participants as the trial progressed 2) impact on trial findings of weighting data according to deprivation (Townsend) fifths in the sample and target populations. 1) a) Recruits (n = 454) were less deprived than the target population, matched for area of residence and delivery dates (n = 6,893) (mean [SD] deprivation scores 0.09[4.21] and 0.79[4.08], t = 3.44, df = 511, p<0.001). b) i) As the trial progressed, representation of the most deprived decreased. These participants and smokers were less likely to be retained at 6 months (n = 430[95%]) (OR 0.29,0.13-0.67 and 0.20,0.09-0.46), and 2 years (n = 380[84%]) (aOR 0.68,0.50-0.93 and 0.55,0.28-1.09), and consent to infant blood sample donation (n = 220[48%]) (aOR 0.72,0.57-0.92 and 0.43,0.22-0.83). ii) Mothers interested in probiotics or research or reporting infants' adverse events or rashes were more likely to attend research clinics and consent to skin-prick testing. Mothers participating to help children were more likely to consent to infant blood sample donation. 2) In one trial outcome, atopic eczema, the intervention had a positive effect only in the over-represented, least deprived group. Here, data weighting attenuated risk reduction from 6.9%(0.9-13.1%) to 4.6%(-1.4-+10.5%), and OR from 0.40(0.18-0.91) to 0.56(0.26-1.21). Other findings were unchanged., Conclusions: Potential for volunteer bias intensified during the trial, due to non-participation of the most deprived and smokers. However, these were not the only predictors of non-participation. Data weighting quantified volunteer bias and modified one important trial outcome., Trial Registration: This randomised, double blind, parallel group, placebo controlled trial is registered with the International Standard Randomised Controlled Trials Register, Number (ISRCTN) 26287422. Registered title: Probiotics in the prevention of atopy in infants and children.

Background: Achieving knowledge translation in healthcare is growing in importance but methods to capture impact of research are not well developed. We present an attempt to capture impact of a programme of research in prehospital emergency care, aiming to inform the development of EMS models of care that avoid, when appropriate, conveyance of patients to hospital for immediate care., Methods: We describe the programme and its dissemination, present examples of its influence on policy and practice, internationally, and analyse routine UK statistics to determine whether conveyance practice has changed., Results: The programme comprises eight research studies, to a value of > £4 m. Findings have been disseminated through 18 published papers, cited 274 times in academic journals. We describe examples of how evidence has been put into practice, including new models of care in Canada and Australia. Routine statistics in England show that, alongside rising demand, conveyance rates have fallen from 90% to 58% over a 12-year period, 2,721 million fewer journeys, with publication of key studies 2003-2008., Comment: We have set out the rationale, key features, and impact on practice of a programme of publicly funded research. We describe evidence of knowledge translation, whilst recognising limitations in methods for capturing impact.

Background: Morton neuroma is a common cause of neuralgia affecting the web spaces of the toes. Corticosteroid injections are commonly administered as a first-line therapy, but the evidence for their effectiveness is weak. Our primary research aim was to determine whether corticosteroid injection is an effective treatment for Morton neuroma compared with an anesthetic injection as a placebo control., Methods: We performed a pragmatic, patient-blinded randomized trial set within hospital orthopaedic outpatient clinics in Edinburgh, United Kingdom. One hundred and thirty-one participants with Morton neuroma (mean age, fifty-three years; 111 [85%] female) were randomized to receive either corticosteroid and anesthetic (1 mL methylprednisolone [40 mg] and 1 mL 2% lignocaine) or anesthetic alone (2 mL 1% lignocaine). An ultrasonographic image was obtained before treatment, and injections were performed with the needle placed under ultrasonographic guidance. The primary outcome was the difference in patient global assessment of foot health between the two groups at three months after injection. This was measured with use of a 100-unit visual analog scale (VAS) anchored by "best imaginable health state" and "worst imaginable health state.", Results: Compared with the control group, global assessment of foot health in the corticosteroid group was significantly better at three months (mean difference, 14.1 scale points [95% confidence interval, 5.5 to 22.8 points]; p = 0.002). The difference between the groups was also significant at one month. Significant and nonsignificant improvements associated with the corticosteroid injection were observed for measures of pain, function, and patient global assessment of general health at one and three months after injection. The size of the neuroma as determined by ultrasonography did not significantly influence the treatment effect., Conclusions: Corticosteroid injections for Morton neuroma can be of symptomatic benefit for at least three months.

Objective: Explore professional views of changes to gastroenterology service organisation and delivery and barriers and facilitators impacting on change. The work was undertaken as part of an evaluation in endoscopy service provision catalysed by the Modernising Endoscopy Services Programme of the Modernisation Agency., Design: Focus groups followed by analysis and group-working activities identifying key themes., Setting: English and Welsh secondary care gastroenterology units., Participants: 20 professionals working in gastroenterology in England and Wales. Medical, surgical and nursing specialists including endoscopy nurses. Opportunistic sampling to include senior people in leadership and management roles who were directly involved in service modernisation, excluding those involved in the Modernisation Endoscopy Services Programme., Results: Four 1.5 h focus groups took place in 2007. Summative and thematic analyses captured essential aspects of text and achieved consensus on key themes. 4 themes were revealed: 'loss of personal autonomy and erosion of professionalism', 'lack of senior management understanding', 'barriers and facilitators to change' and 'differences between English and Welsh units'. Themes indicated that low staff morale, lack of funding and senior management support were barriers to effective change. Limitations to the study include the disproportionately low number of focus group attendees from English units and the time delay in reporting these findings., Conclusions: Despite ambitions to implement change, ineffective management support continued to hamper modernisation of service organisation and delivery. While the National Health Service Modernisation Agency Modernising Endoscopy Services Programme acted as a catalyst for change, affecting the way staff work, communicate and think, it was not effective in heralding change itself. However, gastroenterologists were keen to consider the potential for change and future service modernisation. The methodological framework of innovative qualitative enquiry offers comprehensive and rigorous enhancement of quantitative studies, including randomised trials, when a mixed methods approach is needed.

Background: This report assesses the association between age of onset of major depression and later suicidality in a sample of 276 recurrently depressed patients recruited for the Oxford/Bangor Staying Well after Depression (SWAD) Trial, and interviewed when in remission., Methods: The study enrolled adult patients with a history of at least three episodes of non-psychotic major depressive disorder from primary care and psychiatric care practices and through community advertisements. At study entry, all participants estimated the age of their first onset of a major depressive episode and completed both self-report and interview-based assessments of past and current suicidal ideation and behavior. Participants were divided into pre-adult and adult onset groups using a cut-off age of 18., Results: Forty-eight percent of the sample reported a pre-adult age of onset. Pre-adult age of onset was significantly associated with suicidality, both from self-report and from interviewer assessment even when adjusting for differences in age, gender, employment status, length of the disorder and early adversity., Limitations: Relevant variables were all assessed through retrospective reports., Conclusions: Pre-adult age of onset is closely associated with risk for and severity of later suicidality, replicating, in a sample of patients assessed when in remission, findings from studies that assessed patients when currently depressed. The association of pre-adult age of onset with suicidality is not due to differences in sociodemographic variables, length of the disorder and early adversity., (Copyright © 2011 Elsevier B.V.

Objectives: The aim of the REMiniscence groups for people with dementia and their family CAREgivers (REMCARE) study was to assess the effectiveness and cost-effectiveness of joint reminiscence groups for people with dementia and their family caregivers as compared with usual care., Design: A multicentre, pragmatic randomised controlled trial with two parallel arms - an intervention group and a usual-care control group - was carried out. A restricted dynamic method of randomisation was used with an overall allocation ratio of 1 : 1, restricted to ensure intervention groups of a viable size. Assessments, blind to treatment allocation, were carried out at baseline, 3 months and 10 months (primary end point)., Setting: Most participants were recruited through NHS Memory Clinics and Community Mental Health Teams for older people. Assessments were usually carried out in the person's home, and treatment groups were held in a variety of community settings., Participants: A total of 488 individuals (mean age 77.5 years) with mild to moderate dementia (meeting Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria), who were initially living in the community, and who had a relative or other caregiver maintaining regular contact, who could act as an informant and was willing and able to participate in the intervention, were recruited to the study. Most carers were spouses (71%). A total of 350 dyads completed the study., Interventions: The intervention consisted of joint reminiscence groups held weekly for 12 consecutive weeks, followed by monthly maintenance sessions for a further 7 months. The sessions followed a treatment manual, and were led by two trained facilitators in each centre, supported by a number of volunteers. Up to 12 dyads were invited to attend each group., Main Outcome Measures: The primary outcome measures were self-reported quality of life for the person with dementia and psychological distress for the carer [General Health Questionnaire-28 item version (GHQ-28)]. Secondary outcome measures included autobiographical memory and activities of daily living for the person with dementia, carer stress for the carer and mood, relationship quality and service use and costs for both parties., Results: The intention-to-treat analysis identified no differences in outcome between the intervention and control conditions on primary or secondary outcomes [self-reported quality of life in Alzheimer's disease: mean difference 0.07, standard error (SE) 0.65; F = 0.48; p = 0.53]. Carers of people with dementia allocated to the reminiscence intervention reported a significant increase in anxiety on a subscale of the GHQ-28 at the 10-month end point (mean difference 1.25, SE 0.5; F = 8.28; p = 0.04). Compliance analyses suggested some benefits for people with dementia who attended more reminiscence sessions; however, carers attending more groups showed increased caregiving stress. Use of health- and social-care services was modest, with no significant difference in service use between conditions. Owing to negligible difference in quality-adjusted life-year gains (derived from European Quality of Life-5 Dimensions) between the conditions the planned full economic analysis was curtailed., Conclusions: This trial does not provide support for the effectiveness or cost-effectiveness of joint reminiscence groups for people with dementia and their carers. Although there may be some beneficial effects for people with dementia who attend sessions as planned, this must be viewed in the context of raised anxiety and stress in their carers. The reasons for these discrepant outcomes need to be explored further, and may necessitate reappraisal of the movement towards joint interventions., Trial Registration: Current Controlled Trials ISRCTN42430123., Funding: This project was funded by the NIHR Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 16, No. 48.

A flexible, generalized method of treatment allocation is proposed. The method uses a set of controlling parameters that enables the generic algorithm to produce a family of possible outcomes ranging from simple randomization to deterministic allocation. The method controls balance at stratum level, stratification level and overall without detriment to the predictability of the method. The paper lists the desirable characteristics of allocation methods and shows that the proposed method fulfils the majority and is easy to use in the clinical context, once the coding has been established. An explanation of the method for 2, 3 and 4 treatment group allocations is given. Simulations demonstrate the flexibility of the method., (Copyright © 2011 John Wiley & Sons, Ltd.)

Background: There is a lack of high quality, child-centred and effective health information to support development of self-care practices and expertise in children with acute and long-term conditions. In type 1 diabetes, clinical guidelines indicate that high-quality, child-centred information underpins achievement of optimal glycaemic control with the aim of minimising acute readmissions and reducing the risk of complications in later life. This paper describes the development of a range of child-centred diabetes information resources and outlines the study design and protocol for a randomized controlled trial to evaluate the information resources in routine practice. The aim of the diabetes information intervention is to improve children and young people's quality of life by increasing self-efficacy in managing their type 1 diabetes., Methods/design: We used published evidence, undertook qualitative research and consulted with children, young people and key stakeholders to design and produce a range of child-centred, age-appropriate children's diabetes diaries, carbohydrate recording sheets, and assembled child-centred, age-appropriate diabetes information packs containing published information in a folder that can be personalized by children and young people with pens and stickers. Resources have been designed for children/young people 6-10; 11-15; and 16-18 years.To evaluate the information resources, we designed a pragmatic randomized controlled trial to assess the effectiveness, cost effectiveness, and implementation in routine practice of individually tailored, age-appropriate diabetes diaries and information packs for children and young people age 6-18 years, compared with currently available standard practice.Children and young people will be stratified by gender, length of time since diagnosis (< 2 years and > 2 years) and age (6-10; 11-15; and 16-18 years). The following data will be collected at baseline, 3 and 6 months: PedsQL (generic, diabetes and parent versions), and EQ-5 D (parent and child); NHS resource use and process data (questionnaire and interview). Baseline and subsequent HbA1c measurements, blood glucose meter use, readings and insulin dose will be taken from routine test results and hand-held records when attending routine 3-4 monthly clinic visits.The primary outcome measure is diabetes self-efficacy and quality-of-life (Diabetes PedsQL). Secondary outcomes include: HbA1c, generic quality of life, routinely collected NHS/child-held data, costs, service use, acceptability and utility., Trial Registration: ISRCTN17551624.

Background: Over the last 30 years options for collecting self-reported data in health surveys and questionnaires have increased with technological advances. However, mode of data collection such as face-to-face interview or telephone interview can affect how individuals respond to questionnaires. This paper adapts a framework for understanding mode effects on response quality and applies it to a health research context., Discussion: Data collection modes are distinguished by key features (whether the survey is self- or interviewer-administered, whether or not it is conducted by telephone, whether or not it is computerised, whether it is presented visually or aurally). Psychological appraisal of the survey request will initially entail factors such as the cognitive burden upon the respondent as well as more general considerations about participation. Subsequent psychological response processes will further determine how features of the data collection mode impact upon the quality of response provided. Additional antecedent factors which may further interact with the response generation process are also discussed. These include features of the construct being measured such as sensitivity, and of the respondent themselves (e.g. their socio-demographic characteristics). How features of this framework relate to health research is illustrated by example., Summary: Mode features can affect response quality. Much existing evidence has a broad social sciences research base but is of importance to health research. Approaches to managing mode feature effects are discussed. Greater consideration must be given to how features of different data collection approaches affect response from participants in studies. Study reports should better clarify such features rather than rely upon global descriptions of data collection mode.

Background: Psychological treatments for dementia are widely used in the UK and internationally, but only rarely have they been standardised, adequately evaluated or systematically implemented. There is increasing recognition that psychosocial interventions may have similar levels of effectiveness to medication, and both can be used in combination. Cognitive Stimulation Therapy (CST) is a 7-week cognitive-based approach for dementia that has been shown to be beneficial for cognition and quality of life and is cost-effective, but there is less conclusive evidence for the effects of CST over an extended period., Methods/design: This multi-centre, pragmatic randomised controlled trial (RCT) to assess the effectiveness and cost-effectiveness of Maintenance CST groups for dementia compares a intervention group who receive CST for 7 weeks followed by the Maintenance CST programme once a week for 24 weeks with the control group who receive CST for 7 weeks, followed by treatment as usual for 24 weeks.The primary outcome measures are quality of life of people with dementia assessed by the QoL-AD and cognition assessed by the ADAS-Cog. Secondary outcomes include the person with dementia's mood, behaviour, activities of daily living, ability to communicate and costs; as well as caregiver health-related quality of life. Using a 5% significance level, comparison of 230 participants will yield 80% power to detect a standardised difference of 0.39 on the ADAS-Cog between the groups. The trial includes a cost-effectiveness analysis from a public sector perspective., Discussion: A pilot study of longer-term Maintenance CST, offering 16 weekly sessions of maintenance following the initial CST programme, previously found a significant improvement in cognitive function (MMSE) for those on the intervention group. The study identified the need for a large-scale, multi-centre RCT to define the potential longer-term benefits of continuing the therapy. This study aims to provide definitive evidence of the potential efficacy of maintenance CST and establish how far the long-term benefits can be compared with antidementia drugs such as cholinesterase inhibitors.

Background: Depression is often a chronic relapsing condition, with relapse rates of 50-80% in those who have been depressed before. This is particularly problematic for those who become suicidal when depressed since habitual recurrence of suicidal thoughts increases likelihood of further acute suicidal episodes. Therefore the question how to prevent relapse is of particular urgency in this group., Methods/design: This trial compares Mindfulness-Based Cognitive Therapy (MBCT), a novel form of treatment combining mindfulness meditation and cognitive therapy for depression, with both Cognitive Psycho-Education (CPE), an equally plausible cognitive treatment but without meditation, and treatment as usual (TAU). It will test whether MBCT reduces the risk of relapse in recurrently depressed patients and the incidence of suicidal symptoms in those with a history of suicidality who do relapse. It recruits participants, screens them by telephone for main inclusion and exclusion criteria and, if they are eligible, invites them to a pre-treatment session to assess eligibility in more detail. This trial allocates eligible participants at random between MBCT and TAU, CPE and TAU, and TAU alone in a ratio of 2:2:1, stratified by presence of suicidal ideation or behaviour and current anti-depressant use. We aim to recruit sufficient participants to allow for retention of 300 following attrition. We deliver both active treatments in groups meeting for two hours every week for eight weeks. We shall estimate effects on rates of relapse and suicidal symptoms over 12 months following treatment and assess clinical status immediately after treatment, and three, six, nine and twelve months thereafter., Discussion: This will be the first trial of MBCT to investigate whether MCBT is effective in preventing relapse to depression when compared with a control psychological treatment of equal plausibility; and to explore the use of MBCT for the most severe recurrent depression--that in people who become suicidal when depressed.

Objectives: To explore the experiences of individuals with chronic conditions who are also caring for another person, usually a family member., Method: A postal questionnaire was distributed to carers across Wales on three occasions approximately 18 months apart. It included the SF-12v2 together with fixed-choice and open-ended questions relating to carer demographics, carer assessment, support needs, services received and care recipient's medical condition. A sub-sample of these carers was invited to take part in face-to-face interviews to allow for more in-depth exploration of their circumstances., Results: The carers with chronic conditions experienced a decline in their physical health over time whereas the physical health of carers without a chronic condition remained stable. There was also evidence of carers neglecting their own health because of their caring responsibilities. Despite their health problems, over time the carers with chronic conditions received no more support than other carers., Discussion: This article indicates that there are carers who are themselves suffering from a physical condition or conditions that suggest they are in need of care. Despite these difficulties, these carers are caring for people with quite severe conditions, without any help above that available to other carers.

Background: The growing number of people with dementia, and the increasing cost of care, provides a major incentive to develop and test methods of supporting them in the community for longer. Most attention has been given to pharmacological interventions, but there is increasing recognition that psychosocial interventions may be equally effective, even preferable where medication has negative side-effects. Reminiscence groups, run by professionals and volunteers, which use photographs, recordings and other objects to trigger personal memories are probably the most popular therapeutic approach to working with people with dementia, but there is little evidence for their effectiveness and cost-effectiveness. The recent inclusion of family carers in groups with people with dementia, notably in our own pilot studies, has generated informal evidence that this joint approach improves relationships between people with dementia and their carers, and benefits both., Design and Methods: This multi-centre, pragmatic randomised controlled trial (RCT) to assess the effectiveness and cost-effectiveness of joint reminiscence groups for people with dementia and their family care-givers has two parallel arms--an intervention group and a control group who receive care as usual. The intervention consists of joint reminiscence groups held weekly for twelve consecutive weeks, followed by monthly maintenance sessions for a further seven months.The primary outcome measures are the quality of life of people with dementia, as assessed by QoL-AD, and their care-givers' mental health as assessed by the GHQ-28. Secondary outcomes include: the autobiographical memories of people with dementia; the quality of the relationship between them and their care-givers; and the levels of depression and anxiety felt by them and their care-giver. Using a 5% significance level, comparison of 200 pairs attending joint reminiscence groups with 200 pairs receiving usual treatment will yield 80% power to detect a standardised difference of 0.38 in the QoL-AD rated by the person with dementia and 0.28 in the GHQ-28 or carer-rated QoL-AD. The trial will include a cost-effectiveness analysis from a public sector perspective., Discussion: Our Cochrane review (2005) on reminiscence therapy for people with dementia did not identify any rigorous trials or economic analyses in this field., Trial Registration: ISRCTN42430123.
