Parent satisfaction with lotion, cream, gel and ointment emollient types: secondary analysis of the Best Emollients for Eczema study.

BACKGROUND: The main determinant of emollient effectiveness is whether it is used, which in turn is linked with user satisfaction. OBJECTIVES: To compare parental satisfaction with emollient type for the treatment of childhood eczema. METHODS: Secondary analysis of data from the Best Emollients for Eczema (BEE) trial was undertaken. In total, 550 children aged between 6 months and 12 years were recruited from primary care in England and randomized to use a lotion, cream, gel or ointment as their main emollient for 16 weeks. At week, 16 parents were asked to complete an Emollient Satisfaction Questionnaire (ESQ). Completion rates and scores were compared, using χ2 test, t-test calculations and one-way Anova as appropriate. RESULTS: Data on 378 participants (68.7% of those randomized) were analysed. Mean ESQ scores were gel 20.9 (SD 5.3), lotion 20.4 (SD 5.6), cream 18.8 (SD 6.3) and ointment 15.2 (SD 6.8) (P < 0.001). In pairwise comparisons, there was a statistically significant difference in mean ESQ scores between ointment and lotion (P < 0.001), ointment and cream (P < 0.001) and ointment and gel (P < 0.001) but not between lotion, cream and gel. Participants using lotions had highest overall satisfaction and were most likely to continue using their emollient. ESQ scores were correlated with reported emollient use and improvements in parent-reported eczema severity. CONCLUSIONS: Overall, lotions and gels were favoured over creams and ointments. Although satisfaction is determined by personal preference, these results will aid parents, clinicians and children to find the right emollient(s) for them.

Capturing and reporting topical treatment use in childhood eczema: lessons for data collection in eczema trials.

BACKGROUND: Emollients and topical corticosteroids (TCS) prevent and treat flares in eczema. However, topical treatment use is poorly recorded and reported in clinical trials. There is no clear consensus of how best to capture and summarise topical treatment use. OBJECTIVES: To explore different ways of capturing and reporting topical treatment use in childhood eczema. METHODS: Secondary data analysis using 450 participants from the Best Emollients for Eczema (BEE) trial. Participants were allocated to use one type of emollient (lotion, cream, gel, or ointment) 'twice daily and when required' for 16 weeks. Otherwise, clinical management remained unchanged. Parents completed weekly questions about topical therapy use and eczema symptoms. Two versions of topical treatment use questionnaires were used. The first (n=202, 44.9%) asked parents to report treatment use on days 1-7, starting completion on the day they were randomised. The second (n=248, 55.1%) reported use by day of the week (Monday to Sunday), starting completion the first Monday after randomisation. Both underwent Patient and Public Involvement (PPI) review, but the second version was tested more thoroughly using cognitive interviewing techniques, following parent feedback that questions on the first version were confusing. Descriptive statistics compared questionnaire completion and differences in emollient and TCS use. RESULTS: Overall, questionnaire completion for both emollient and TCS use decreased with time: but at weeks 1 and 16 were 84.7% (381/450) and 58.9% (265/450) for emollient use, and 94.2% (424/450) and 80.4% (362/450) for TCS use, respectively. Fewer emollient use questionnaires were completed with first (33.5%) than the second (87.9%) version (p<0.001). TCS use questionnaire completion were similar for both (84.9% and 87.4%, p=0.002). We present different ways of summarising topical treatment use. CONCLUSIONS: While questionnaire completion was similar for TCS use, emollient use data completeness was higher in the second version. When designing questionnaires, balancing the detail and complexity of questions is important, especially if being collected as a secondary outcome measure. Numerous ways of summarising the same data can provide different information. Future collection and reporting of treatment use should reflect specific trial aims.

Do temperature changes cause eczema flares? An English cohort study.

BACKGROUND: It is unclear if ambient temperature changes affect eczema. It is also unclear if people with worse disease are more susceptible to weather-related flares, or specific types of emollient offer protection. OBJECTIVES: To investigate the effect of short-term temperature variations on eczema symptoms in children. METHODS: Data from a UK cohort of 519 children with eczema were combined with data from the Hadley Centre's Integrated Surface Database. Hot and cold weeks were defined by average regional temperature > 75th or < 25th percentile, January 2018 to February 2020. Eczema flares were defined as ≥ 3-point change in Patient-Oriented Eczema Measure (POEM). Random-effects logistic regression models were used to estimate the odds ratios of flares in hot and cold weeks (reference group: temperate weeks). RESULTS: The baseline mean age was 4.9 years (SD 3.2) and the POEM score was 9.2 (SD 5.5). From the 519 participants, there were 6796 consecutively paired POEMs and 1082 flares. Seasonal variation in POEM scores was observed, suggesting symptoms worsening in winter and improving in summer. Odds ratios of flares were: 1.15 [95% confidence interval (CI) 0.96-1.39, P = 0.14] in cold weeks and 0.85 (95% CI 0.72-1.00, P = 0.05) in hot weeks. The likelihood ratio test showed no evidence of this differing by disease severity (P = 0.53) or emollient type used (P = 0.55). CONCLUSIONS: Our findings are consistent with previous studies demonstrating either improvements in eczema symptoms or reduced flares in hot weather. Worse disease and different emollient types did not increase susceptibility or provide protection against temperature changes. Further work should investigate the role of sunlight, humidity, pollution and other environmental factors.

Frequency of guideline-defined cow's milk allergy symptoms in infants: Secondary analysis of EAT trial data.

BACKGROUND: Non-IgE-mediated Cow's Milk Allergy (CMA) has a prevalence of less than 1% in children. Guidelines developed to help non-specialists diagnose CMA may lead to misattribution of normal symptoms and contribute to overdiagnosis of CMA. We sought to establish the frequency of symptoms during infancy associated with non-IgE-mediated CMA, using the international Milk Allergy in Primary Care (iMAP) guideline as representative of CMA guidelines more generally. METHOD: Secondary analysis of the Enquiring About Tolerance (EAT) randomized controlled trial (ISRCTN 14254740; 1303 exclusively breastfed 3-month-old healthy infants). Key outcomes were ≥2 iMAP symptoms associated with 'mild-moderate' and 'severe' non-IgE-mediated CMA. RESULTS: Whilst breastfeeding and parental atopy rates were higher than the general population, participants were otherwise similar to the population of England and Wales. Two or more non-IgE CMA symptoms were reported by 25% families for mild-moderate and 1.4% for severe symptoms each month between ages 3 and 12 months, peaking at 38% with ≥2 mild-moderate and 4.3% ≥2 severe symptoms at three months, when participants were not directly consuming cow's milk. 74% of participants reported ≥2 mild-moderate symptoms and 9% ≥2 severe symptoms in at least one month during this period. At six months there was no evidence of difference in the proportion of children with ≥2 symptoms between those consuming (29.5% mild-moderate, 1.8% severe) and not consuming cow's milk (35.3% mild-moderate, 2.2% severe). Mean monthly reporting of ≥2 symptoms was also no different between those with (15.8% mild-moderate, 1.1% severe) or without eczema at baseline (16.7% mild-moderate, 1.3% severe). CONCLUSIONS: Guideline-defined symptoms of non-IgE-mediated CMA are very common in infants. Guidelines may promote milk allergy overdiagnosis by labelling normal infant symptoms as possible milk allergy.

Using datasets to ascertain the generalizability of clinical cohorts: the example of the European QUALity study on the treatment of advanced chronic kidney disease.

BACKGROUND: Cohort studies are among the most robust of observational studies but have issues with external validity. This study assesses threats to external validity (generalizability) in the European QUALity (EQUAL) study, a cohort study of people >65 years of age with Stage 4/5 chronic kidney disease. METHODS: Patients meeting the EQUAL inclusion criteria were identified in The Health Improvement Network database and stratified into those attending renal units, a secondary care cohort (SCC) and a not primary care cohort (PCC). Survival, progression to renal replacement therapy (RRT) and hospitalization were compared. RESULTS: The analysis included 250, 633 and 2464 patients in EQUAL, PCC and SCC. EQUAL had a higher proportion of men compared with PCC and SCC (60.0% versus 34.8% versus 51.4%). Increasing age ≥85 years {odds ratio [OR] 0.25 [95% confidence interval (CI) 0.15-0.40]} and comorbidity [Charlson Comorbidity Index ≥4, OR 0.69 (95% CI 0.52-0.91)] were associated with non-participation in EQUAL. EQUAL had a higher proportion of patients starting RRT at 1 year compared with SCC (8.1% versus 2.1%; P < 0.001). Patients in the PCC and SCC had increased risk of hospitalization [incidence rate ratio 1.76 (95% CI 1.27-2.47) and 2.13 (95% CI 1.59-2.86)] and mortality at 1 year [hazard ratio 3.48 (95% CI 2.1-5.7) and 1.7 (95% CI 1.1-2.7)] compared with EQUAL. CONCLUSIONS: This study provides evidence of how participants in a cohort study can differ from the broader population of patients, which is essential when considering external validity and application to local practice.

Emollient satisfaction questionnaire: validation study in children with eczema.

BACKGROUND: Emollients are used as maintenance therapy for all severities of eczema but there is a lack of head-to-head comparisons of effectiveness and acceptability. AIM: To determine the validity of a self-report questionnaire designed to assess user satisfaction with a given emollient and to report the findings. METHODS: Data were analysed from the Choice of Moisturiser for Eczema Treatment trial, which compared four emollient types (Aveeno® lotion, Diprobase® cream, Doublebase® gel and Hydromol® ointment) in children aged < 5 years with clinically diagnosed eczema. An emollient satisfaction questionnaire was completed after 12 weeks. Responses for individual items were scored from 0 to 4. Total scores ranged from 0 to 28 (low to high satisfaction). Completion rates and distributions of responses for individual items and total scores, categorized by emollient type, were assessed, and two hypotheses were tested to determine the questionnaire's construct validity. RESULTS: Data from 77.2% (152 of 197) of participants were analysed. One item was rejected because of a high rate (44.7%) of 'don't know' responses, leaving seven items with high completion rates (98.7%) and weak evidence of floor or ceiling effects. A positive association was observed between total score and overall emollient satisfaction (Spearman correlation 0.78; P < 0.001). Total scores were highest (mean ± SD 23.5 ± 3.9) in the lotion group and lowest (18.4 ± 4.6) in the ointment group. CONCLUSION: The emollient satisfaction questionnaire appears to have good validity. Further work is required to validate the questionnaire in other settings and to assess its reliability.

Effectiveness and cost-effectiveness of the PLAN-A intervention, a peer led physical activity program for adolescent girls: results of a cluster randomised controlled trial.

BACKGROUND: Physical activity is associated with improved health. Girls are less active than boys. Pilot work showed that a peer-led physical activity intervention called PLAN-A was a promising method of increasing physical activity in secondary school age girls. This study examined the effectiveness and cost-effectiveness of the PLAN-A intervention. METHODS: We conducted a cluster randomised controlled trial with Year 9 (13-14 year old) girls recruited from 20 secondary schools. Schools were randomly assigned to the PLAN-A intervention or a non-intervention control group after baseline data collection. Girls nominated students to be peer leaders. The top 18 % of girls nominated by their peers in intervention schools received three days of training designed to prepare them to support physical activity. Data were collected at two time points, baseline (T0) and 5-6 months post-intervention (T1). Participants wore an accelerometer for seven days to assess the primary outcome of mean weekday minutes of moderate-to-vigorous physical activity (MVPA). Multivariable mixed effects linear regression was used to estimate differences in the primary outcome between the two arms on an Intention-to-Treat (ITT) basis. Resource use and quality of life were measured and a within trial economic evaluation from a public sector perspective was conducted. RESULTS: A total of 1558 girls were recruited to the study. At T0, girls in both arms engaged in an average of 51 min of MVPA per weekday. The adjusted mean difference in weekday MVPA at T1 was - 2.84 min per day (95 % CI = -5.94 to 0.25) indicating a slightly larger decline in weekday MVPA in the intervention group. Results were broadly consistent when repeated using a multiple imputation approach and for pre-specified secondary outcomes and sub-groups. The mean cost of the PLAN-A intervention was £2817 per school, equivalent to £31 per girl. Economic analyses indicated that PLAN-A did not lead to demonstrable cost-effectiveness in terms of cost per unit change in QALY. CONCLUSIONS: This study has shown that the PLAN-A intervention did not result in higher levels of weekday MVPA or associated secondary outcomes among Year 9 girls. The PLAN-A intervention should not be disseminated as a public health strategy. TRIAL REGISTRATION: ISRCTN14539759 -31 May, 2018.

Protocol for a cluster randomised controlled trial of a Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A).

BACKGROUND: Adolescent girls are less physically active than recommended for health, and levels decline further as they approach adulthood. Peers can influence adolescent girls' physical activity. Interventions capitalising on peer support could positively impact physical activity behaviour in this group. Building on promising feasibility work, the purpose of this cluster randomised controlled trial is to assess whether the Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A) increases adolescent girls' physical activity and is cost effective. METHODS: PLAN-A is a two-arm secondary school-based cluster randomised controlled trial, conducted with girls aged 13-14 years from twenty schools in the south west of England. The intervention requires participants to nominate influential girls within their year group to become peer supporters. The top 15% of girls nominated in each school receive three days of training designed to prepare them to support their peers to be more physically active during a ten-week intervention period. Data will be collected at two time points, at baseline (T0) and 5-6 months post-intervention (T1). Schools will be randomly allocated to the intervention (n = 10) or control (n = 10) arm after T0. At each time point, all consenting participants will wear an accelerometer for seven days to assess the primary outcome of mean weekday minutes of moderate-to-vigorous physical activity. Multivariable mixed effects linear regression will be used to estimate differences in the primary outcome between the two arms and will be examined on an Intention-to-Treat (ITT) basis. A self-report psychosocial questionnaire will be completed by participants to assess self-esteem and physical activity motivation. Resource use and quality of life will be measured for the purposes of an economic evaluation. A mixed-methods process evaluation will be conducted to explore intervention fidelity, acceptability and sustainability. Analysis of quantitative process evaluation data will be descriptive, and the framework method will be used to analyse qualitative data. DISCUSSION: This paper describes the protocol for the PLAN-A cluster randomised controlled trial, a novel approach to increasing adolescent girls' physical activity levels through peer support. TRIAL REGISTRATION: ISRCTN14539759-31 May, 2018.

A multicenter cohort study of potential living kidney donors provides predictors of living kidney donation and non-donation.

This multicenter prospective potential living kidney donor cohort study investigated which sociodemographic and other factors predict progression to living kidney donation or donor withdrawal as little is known on this topic. Therefore, we examined data on individuals undergoing living donor assessment at seven hospitals in the United Kingdom. Multivariable logistic regression was used to explore the relationships between donor and recipient characteristics and likelihood of kidney donation. A total of 805 individuals presented for directed donation to 498 intended recipients, of which 112 received a transplant from a living donor. Potential donors were less likely to donate if their intended recipient was female rather than male with an odds ratio of 0.60, a friend rather than relative 0.18, or had renal failure due to a systemic disease rather than another cause 0.41. The most socioeconomically deprived quintile was less likely to donate than the least 0.49, but the trend with deprivation was consistent with chance. Higher body mass index was associated with a lower likelihood of donation (odds ratio per each kg/m2 increase, 0.92). Younger potential donors (odds ratio per each year increase 0.97), those of nonwhite ethnicity 2.98, and friend donors 2.43 were more likely to withdraw from work-up. This is the first study in the United Kingdom of potential living kidney donors to describe predictors of non-donation. Qualitative work with individuals who withdraw might identify possible ways of supporting those who wish to donate but experience difficulties doing so.

Occupational allergy to fruit flies (Drosophila melanogaster) in laboratory workers.

OBJECTIVES: Drosophila melanogaster (the 'fruit fly') is commonly used in genetic research, but there is only one report of IgE-associated allergy in exposed workers. 4 newly identified cases prompted us to examine the extent of this problem in a university laboratory. Our aim in this study is to determine the prevalence and determinants of sensitisation to fruit flies in a population of exposed workers. METHODS: In a cross-sectional study, we surveyed 286 employees working in a department carrying out research involving D. melanogaster. Sensitisation was assessed by specific IgE measurement in serum and examined in relation to symptoms and to estimated exposure to fruit flies. RESULTS: The overall prevalence of specific sensitisation was 6% with a clear relationship to increasing frequency/intensity of exposure (p trend<0.001). Work-related eye/nose, chest or skin symptoms were reported by substantial proportions of participants but for most of these there was no evidence of specific sensitisation to fruit fly. The overall prevalence of any work-related symptoms and sensitisation was 2.4%, rising to 7.1% in those working in high exposure groups. CONCLUSIONS: We were able to demonstrate, for the first time, a clear exposure-response relationship between fruit fly exposure and specific sensitisation. Facilities housing fruit flies should carefully consider methods to reduce exposure levels in the workplace.

A longitudinal study characterising a large adult primary ciliary dyskinesia population.

Primary ciliary dyskinesia (PCD) in adults has not been well described. In this retrospective observational study we aimed to characterise a large adult population and identify features associated with disease progression.We retrospectively analysed 151 adult patients at a single tertiary centre at baseline and longitudinally for a median of 7 years.We found significant variation in age at diagnosis (median 23.5 years; range <1-72 years). Older age at diagnosis was associated with impaired baseline forced expiratory volume in 1 s (FEV1) (r= -0.30, p=0.01) and increased Pseudomonas aeruginosa colonisation (difference in medians 17 years (95% CI 4.5-20 years); p=0.002). Lung function decline was estimated at FEV1 decline of 0.49% predicted per year. Lung function decline was associated with ciliary ultrastructure, with microtubular defect patients having the greatest decline (p=0.04). High-resolution computed tomography (HRCT) scores of severity of bronchial wall dilatation (p<0.001) and extent of bronchiectasis (p=0.03) additionally showed evidence of modifying FEV1 decline with age.Our study reveals that a large proportion of adult PCD patients are diagnosed late, with impaired FEV1 and increased P. aeruginosa colonisation. Increased disease burden on HRCT and ciliary ultrastructure may predict progressive lung function decline. This study characterises a large adult PCD population, identifies features associated with disease progression and highlights the need for prospective trials to determine whether early diagnosis of high-risk subgroups alongside optimal management can modify disease progression.

Children and young adults with CF in the USA have better lung function compared with the UK.

BACKGROUND: People with cystic fibrosis (CF) are managed differently in the USA and UK providing an opportunity to learn from differences in practice patterns. OBJECTIVES: To compare cross-sectional demographics, practice patterns and clinical outcomes between US and UK CF patients. METHODS: This was a cross-sectional study using 2010 data from patients in the US Cystic Fibrosis Foundation and the UK Cystic Fibrosis patient registries. The a priori outcome measures of interest were lung function and nutritional status. Descriptive statistics and two sample comparisons were performed. Stratification and multivariable linear regression were used to adjust for confounding. RESULTS: The study cohort included 13 777 children and 11 058 adults from the USA and 3968 children and 3965 adults from the UK. In children, mean body mass index centiles were similar. Lung function (FEV1 and FVC% predicted) was significantly higher in US patients ages 6-25 years of age. In a regression model adjusted for only age, FEV1% predicted was on average 3.31% of predicted (95% CI 2.65 to 3.96) higher in the USA compared with the UK. When adjusted for age, age at diagnosis, gender, pancreatic insufficiency and genotype, FEV1% predicted was on average 3.03% of predicted (95% CI 2.37 to 3.69) higher in the USA compared with the UK These differences persisted despite adjustment for possible confounders. Hypertonic saline and dornase alfa were much more commonly prescribed in US children. CONCLUSIONS: Children and young adults with CF have better lung function in the USA compared with the UK despite similar nutritional status.

Factors associated with FEV1 decline in cystic fibrosis: analysis of the ECFS patient registry.

Pulmonary insufficiency is the main cause of death in cystic fibrosis (CF). We analysed forced expiratory volume in 1 s (FEV1) data of 14,732 patients registered in the European Cystic Fibrosis Society Patient Registry (ECFSPR) database in 2007. We used linear and logistic regressions to investigate associations between FEV1 % predicted and clinical outcomes. Body mass index (BMI), chronic infection by Pseudomonas aeruginosa, pancreatic status and CF-related diabetes (CFRD) showed a statistically significant (all p<0.0001) and clinically relevant effect on FEV1 % pred after adjusting for age. Patients with a lower BMI experience a six-fold increased odds ratio (95% CI 5.0-7.3) of having severe lung disease (FEV1 <40% pred) compared to patients with normal BMI. Being chronically infected with P. aeruginosa increases the odds ratio of severe lung disease by 2.4 (95% CI 2.0-2.7), and patients with pancreatic insufficiency experience a 2.0-fold increased odds ratio (95% CI 1.6-2.5) of severe lung disease compared to pancreatic sufficient patients. Patients with CFRD have a 1.8-fold increased odds ratio (95% CI 1.6-2.2) compared to patients not affected. These potential risk factors for pulmonary disease in patients with CF are to some degree preventable or treatable. We emphasise the importance of their early identification through frequent routine tests, the implementation of infection control measures, and a timely initiation of relevant therapies.

Education to improve timeliness of shingles diagnosis in primary care: a cluster randomised study within a trial with nested qualitative study.

BACKGROUND: Herpes zoster (shingles) is normally diagnosed clinically. Timely diagnosis is important so that antiviral treatment can be started soon after rash onset. AIM: To assess whether a practice-level educational intervention, aimed at non-clinical patient-facing staff, improves the timely assessment of patients with shingles. DESIGN AND SETTING: This was a cluster randomised study within a trial (SWAT) with nested qualitative study in general practices in England. METHOD: Practices were cluster randomised 1:1, stratified by centre and minimised by practice list size and Index of Multiple Deprivation score. Intervention practices were sent educational materials, highlighting the common presenting features of shingles and what action to take if suspected. The primary and secondary outcomes were the mean proportion of patients per practice seen within 72 and 144 h of rash onset, respectively. Comparison between groups was conducted using linear regression, adjusting for randomisation variables. Semi-structured interviews with practice staff in intervention practices explored views and opinions about the intervention. RESULTS: In total, 67 practices were enrolled; 34 randomised to the intervention and 33 to the control. The mean difference in proportion of patients seen within 72 and 144 h was -0.132 (95% confidence interval [CI] = -0.308 to 0.043) and -0.039 (95% CI = -0.158 to 0.080), respectively. In intervention practices, 90.9% reported distributing the educational materials; however, engagement with these was suboptimal. Twelve participants were interviewed, and the poster component of the intervention was said to be easiest to implement. CONCLUSION: Our educational intervention did not improve the timely assessment of patients with shingles. This may be the result of poor intervention engagement.

Cost-effectiveness of a primary healthcare intervention to treat male lower urinary tract symptoms: the TRIUMPH cluster randomised controlled trial.

OBJECTIVES: To estimate the cost-effectiveness of a primary care intervention for male lower urinary tract symptoms (LUTS) compared with usual care. DESIGN: Economic evaluation alongside a cluster randomised controlled trial from a UK National Health Service (NHS) perspective with a 12-month time horizon. SETTING: Thirty NHS general practice sites in England. PARTICIPANTS: 1077 men aged 18 or older identified in primary care with bothersome LUTS. INTERVENTIONS: A standardised and manualised intervention for the treatment of bothersome LUTS was compared with usual care. The intervention group (n=524) received a standardised information booklet with guidance on conservative treatment for LUTS, urinary symptom assessment and follow-up contacts for 12 weeks. The usual care group (n=553) followed local guidelines between general practice sites. MEASURES: Resource use was obtained from electronic health records, trial staff and participants, and valued using UK reference costs. Quality-adjusted life-years (QALYs) were calculated from the EQ-5D-5L questionnaire. Adjusted mean differences in costs and QALYs and incremental net monetary benefit were estimated. RESULTS: 866 of 1077 (80.4%) participants had complete data and were included in the base-case analysis. Over the 12-month follow-up period, intervention and usual care arms had similar mean adjusted costs and QALYs. Mean differences were lower in the intervention arm for adjusted costs -£29.99 (95% CI -£109.84 to £22.63) while higher in the intervention arm for adjusted QALYs 0.001 (95% CI -0.011 to 0.014). The incremental net monetary benefit statistic was £48.01 (95% CI -£225.83 to £321.85) at the National Institute for Health and Care Excellence UK threshold of £20 000 per QALY. The cost-effectiveness acceptability curve showed a 63% probability of the intervention arm being cost-effective at this threshold. CONCLUSIONS: Costs and QALYs were similar between the two arms at 12 months follow-up. This indicates that the intervention can be implemented in general practice at neutral cost. TRIAL REGISTRATION NUMBER: ISRCTN11669964.

Lower urinary tract symptoms in men: the TRIUMPH cluster RCT.

Background: Conservative therapies are recommended as initial treatment for male lower urinary tract symptoms. However, there is a lack of evidence on effectiveness and uncertainty regarding approaches to delivery. Objective: The objective was to determine whether or not a standardised and manualised care intervention delivered in primary care achieves superior symptomatic outcome for lower urinary tract symptoms to usual care. Design: This was a two-arm cluster randomised controlled trial. Setting: The trial was set in 30 NHS general practice sites in England. Participants: Participants were adult men (aged ≥ 18 years) with bothersome lower urinary tract symptoms. Interventions: Sites were randomised 1 : 1 to deliver the TReatIng Urinary symptoms in Men in Primary Health care using non-pharmacological and non-surgical interventions trial intervention or usual care to all participants. The TReatIng Urinary symptoms in Men in Primary Health care using non-pharmacological and non-surgical interventions intervention comprised a standardised advice booklet developed for the trial from the British Association of Urological Surgeons' patient information sheets, with patient and expert input. Patients were directed to relevant sections by general practice or research nurses/healthcare assistants following urinary symptom assessment, providing the manualised element. The healthcare professional provided follow-up contacts over 12 weeks to support adherence to the intervention. Main outcome measures: The primary outcome was the validated patient-reported International Prostate Symptom Score 12 months post consent. Rather than the minimal clinically important difference of 3.0 points for overall International Prostate Symptom Score, the sample size aimed to detect a difference of 2.0 points, owing to the recognised clinical impact of individual symptoms. Results: A total of 1077 men consented to the study: 524 in sites randomised to the intervention arm (n = 17) and 553 in sites randomised to the control arm (n = 13). A difference in mean International Prostate Symptom Score at 12 months was found (adjusted mean difference of -1.81 points, 95% confidence interval -2.66 to -0.95 points), with a lower score in the intervention arm, indicating less severe symptoms. Secondary outcomes of patient-reported urinary symptoms, quality of life specific to lower urinary tract symptoms and perception of lower urinary tract symptoms all showed evidence of a difference between the arms favouring the intervention. No difference was seen between the arms in the proportion of urology referrals or adverse events. In qualitative interviews, participants welcomed the intervention, describing positive effects on their symptoms, as well as on their understanding of conservative care and their attitude towards the experience of lower urinary tract symptoms. The interviews highlighted that structured, in-depth self-management is insufficiently embedded within general practitioner consultations. From an NHS perspective, mean costs and quality-adjusted life-years were similar between trial arms. The intervention arm had slightly lower mean costs (adjusted mean difference of -£29.99, 95% confidence interval -£109.84 to £22.63) than the usual-care arm, and a small gain in quality-adjusted life-years (adjusted mean difference of 0.001, 95% confidence interval -0.011 to 0.014). Conclusions: The intervention showed a small, sustained benefit for men's lower urinary tract symptoms and quality of life across a range of outcome measures in a UK primary care setting. Qualitative data showed that men highly valued the intervention. Intervention costs were marginally lower than usual-care costs. Limitations of the study included that trial participants were unmasked, with limited diversity in ethnicity and deprivation level. Additional research is needed to assess the applicability of the intervention for a more ethnically diverse population.. Trial registration: This trial is registered as ISRCTN11669964.

Urinary problems among men become more common with age. Nearly one-third of all men aged > 65 years experience some urinary symptoms, which can have a substantial effect on their daily lives. Symptoms include needing to pass urine more often, urgently or during the night, and difficulties in passing urine. Men are usually diagnosed and treated by their general practitioner, and should be offered advice on controlling their symptoms themselves (e.g. lifestyle changes and exercises) before trying tablets or surgery. However, it is not known how helpful such advice is, and how general practices can effectively provide it. Thirty general practices in the West of England and Wessex took part in the study. Practices were split into two groups, with each practice providing either the TReatIng Urinary symptoms in Men in Primary Health care using non-pharmacological and non-surgical interventions care package or the practice's usual care to all of its patients in the trial. The TReatIng Urinary symptoms in Men in Primary Healthcare using nonpharmacological and non-surgical interventions care package included a booklet of advice to help control urinary symptoms, with a nurse or healthcare assistant directing men to relevant sections according to their symptoms, and providing follow-up contacts. We mainly assessed the benefits of the TReatIng Urinary symptoms in Men in Primary Healthcare using nonpharmacological and non-surgical interventions care package, compared with usual care, by using a questionnaire on urinary symptoms completed by participants. A total of 1077 men with urinary symptoms that bothered them joined the study. The main result was that men reported greater improvement in urinary symptoms with the TRIUMPH care package than with usual care, 12 months after joining the study. We also found that men receiving the TRIUMPH care package had a slight improvement in quality of life and outlook on their urinary symptoms. There was no difference between the two groups in the number of patients referred to hospital for treatment, the type, number and severity of side effects or cost to the NHS. Overall, the TRIUMPH care package was more effective in treating men with urinary symptoms than usual care by their general practice.

Sertraline for anxiety in adults with a diagnosis of autism (STRATA): study protocol for a pragmatic, multicentre, double-blind, placebo-controlled randomised controlled trial.

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to manage anxiety in adults with an autism diagnosis. However, their effectiveness and adverse effect profile in the autistic population are not well known. This trial aims to determine the effectiveness and cost-effectiveness of the SSRI sertraline in reducing symptoms of anxiety and improving quality of life in adults with a diagnosis of autism compared with placebo and to quantify any adverse effects. METHODS: STRATA is a two-parallel group, multi-centre, pragmatic, double-blind, randomised placebo-controlled trial with allocation at the level of the individual. It will be delivered through recruiting sites with autism services in 4 regional centres in the United Kingdom (UK) and 1 in Australia. Adults with an autism diagnosis and a Generalised Anxiety Disorder Assessment (GAD-7) score ≥ 10 at screening will be randomised 1:1 to either 25 mg sertraline or placebo, with subsequent flexible dose titration up to 200 mg. The primary outcome is GAD-7 scores at 16 weeks post-randomisation. Secondary outcomes include adverse effects, proportionate change in GAD-7 scores including 50% reduction, social anxiety, obsessive-compulsive symptoms, panic attacks, repetitive behaviours, meltdowns, depressive symptoms, composite depression and anxiety, functioning and disability and quality of life. Carer burden will be assessed in a linked carer sub-study. Outcome data will be collected using online/paper methods via video call, face-to-face or telephone according to participant preference at 16, 24 and 52 weeks post-randomisation, with brief safety checks and data collection at 1-2, 4, 8, 12 and 36 weeks. An economic evaluation to study the cost-effectiveness of sertraline vs placebo and a QuinteT Recruitment Intervention (QRI) to optimise recruitment and informed consent are embedded within the trial. Qualitative interviews at various times during the study will explore experiences of participating and taking the trial medication. DISCUSSION: Results from this study should help autistic adults and their clinicians make evidence-based decisions on the use of sertraline for managing anxiety in this population.

Investigating strategies to improve AccesS to Kidney transplantation (the ASK trial): a protocol for a feasibility randomised controlled trial with parallel process evaluation.

BACKGROUND: The UK's living-donor kidney transplant (LDKT) activity falls behind that of many other countries internationally, with less than 20% of those eligible receiving a LDKT each year. Certain individuals with kidney disease in the UK appear to be particularly disadvantaged in accessing a LDKT; the most socioeconomically deprived people with kidney disease are 60% less likely to receive a LDKT than the least deprived. Improving equity in living-donor kidney transplantation has been highlighted as an international research priority. METHODS: This feasibility trial was designed to determine the feasibility of delivery and acceptability of a multicomponent intervention designed to improve access to living-donor kidney transplantation. The intervention comprises three main components: (i) a meeting between a home educator and the transplant candidate for a dedicated discussion about living-donor kidney transplantation, living kidney donation and potential donors; (ii) a standardized letter from a healthcare professional to a candidate's potential donors and (iii) a home-based education and family engagement session including two home educators, the transplant candidate and their family. The primary objectives are to establish the feasibility (i) of delivering the developed intervention in existing care pathways and (ii) of undertaking a randomised controlled trial of the intervention. A mixed-methods parallel process evaluation will investigate the acceptability, implementation and mechanisms of impact of the intervention. The trial is based at two UK hospitals: a transplanting hospital and a non-transplanting referral hospital. Individuals are eligible if they are ≥ 18 years old, are active on the kidney transplant waiting list or have been referred for transplant listing and do not have a potential living-donor undergoing surgical assessment. Randomisation will be undertaken with concealed allocation. Participants will be randomly allocated 1:1 to (i) the intervention or (ii) usual care, stratified by site to ensure a balance in terms of local differences. Minimisation will be used to ensure balance in sex, age group and socioeconomic strata, with probability weighting of 0.8 in order to reduce predictability. The primary outcomes are recruitment (% of those eligible and invited who consent to randomisation) and retention (% of participants completing follow-up). DISCUSSION: Findings will inform the design of a future fully powered, randomised controlled trial to formally evaluate the effectiveness of the intervention at improving equitable access to living-donor kidney transplantation.

Treatment of lower urinary tract symptoms in men in primary care using a conservative intervention: cluster randomised controlled trial.

OBJECTIVE: To determine whether a standardised and manualised care intervention in men in primary care could achieve superior improvement of lower urinary tract symptoms (LUTS) compared with usual care. DESIGN: Cluster randomised controlled trial. SETTING: 30 National Health Service general practice sites in England. PARTICIPANTS: Sites were randomised 1:1 to the intervention and control arms. 1077 men (≥18 years) with bothersome LUTS recruited between June 2018 and August 2019: 524 were assigned to the intervention arm (n=17 sites) and 553 were assigned to the usual care arm (n=13 sites). INTERVENTION: Standardised information booklet developed with patient and expert input, providing guidance on conservative and lifestyle interventions for LUTS in men. After assessment of urinary symptoms (manualised element), general practice nurses and healthcare assistants or research nurses directed participants to relevant sections of the manual and provided contact over 12 weeks to assist with adherence. MAIN OUTCOME MEASURES: The primary outcome was patient reported International Prostate Symptom Score (IPSS) measured 12 months after participants had consented to take part in the study. The target reduction of 2.0 points on which the study was powered reflects the minimal clinically important difference where baseline IPSS is <20. Secondary outcomes were patient reported quality of life, urinary symptoms and perception of LUTS, hospital referrals, and adverse events. The primary intention-to-treat analysis included 887 participants (82% of those recruited) and used a mixed effects multilevel linear regression model adjusted for site level variables used in the randomisation and baseline scores. RESULTS: Participants in the intervention arm had a lower mean IPSS at 12 months (adjusted mean difference -1.81 points, 95% confidence interval -2.66 to -0.95) indicating less severe urinary symptoms than those in the usual care arm. LUTS specific quality of life, incontinence, and perception of LUTS also improved more in the intervention arm than usual care arm at 12 months. The proportion of urology referrals (intervention 7.3%, usual care 7.9%) and adverse events (intervention seven events, usual care eight events) were comparable between the arms. CONCLUSIONS: A standardised and manualised intervention in primary care showed a sustained reduction in LUTS in men at 12 months. The mean difference of -1.81 points (95% confidence interval -0.95 to -2.66) on the IPSS was less than the predefined target reduction of 2.0 points.
