Abstract
BACKGROUND Herpes zoster (shingles) is normally diagnosed clinically. Timely diagnosis is important so 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 Cluster randomised Study Within A Trial (SWAT) with nested qualitative study in General Practices in England. METHODS 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 hours and 144 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 of the intervention. RESULTS 67 practices were enrolled; 34 randomised to intervention, 33 to control. The mean difference in proportion of patients seen within 72 and 144 hours was -0.132 (95% CI -0.308, 0.043) and -0.039 (95% CI -0.158, 0.080), respectively. In intervention practices, 90.5% reported distributing the educational materials, however engagement with these was suboptimal. 12 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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Background Emollients are recommended for children with eczema (atopic eczema/dermatitis). A lack of head-to-head comparisons of the effectiveness and acceptability of the different types of emollients has resulted in a 'trial and error' approach to prescribing. Objective To compare the effectiveness and acceptability of four commonly used types of emollients for the treatment of childhood eczema. Design Four group, parallel, individually randomised, superiority randomised clinical trials with a nested qualitative study, completed in 2021. A purposeful sample of parents/children was interviewed at ≈ 4 and ≈ 16 weeks. Setting Primary care (78 general practitioner surgeries) in England. Participants Children aged between 6 months and 12 years with eczema, of at least mild severity, and with no known sensitivity to the study emollients or their constituents. Interventions Study emollients sharing the same characteristics in the four types of lotion, cream, gel or ointment, alongside usual care, and allocated using a web-based randomisation system. Participants were unmasked and the researcher assessing the Eczema Area Severity Index scores was masked. Main outcome measures The primary outcome was Patient-Oriented Eczema Measure scores over 16 weeks. The secondary outcomes were Patient-Oriented Eczema Measure scores over 52 weeks, Eczema Area Severity Index score at 16 weeks, quality of life (Atopic Dermatitis Quality of Life, Child Health Utility-9 Dimensions and EuroQol-5 Dimensions, five-level version, scores), Dermatitis Family Impact and satisfaction levels at 16 weeks. Results A total of 550 children were randomised to receive lotion (analysed for primary outcome 131/allocated 137), cream (137/140), gel (130/135) or ointment (126/138). At baseline, 86.0% of participants were white and 46.4% were female. The median (interquartile range) age was 4 (2-8) years and the median Patient-Oriented Eczema Measure score was 9.3 (SD 5.5). There was no evidence of a difference in mean Patient-Oriented Eczema Measure scores over the first 16 weeks between emollient types (global p = 0.765): adjusted Patient-Oriented Eczema Measure pairwise differences - cream-lotion 0.42 (95% confidence interval -0.48 to 1.32), gel-lotion 0.17 (95% confidence interval -0.75 to 1.09), ointment-lotion -0.01 (95% confidence interval -0.93 to 0.91), gel-cream -0.25 (95% confidence interval -1.15 to 0.65), ointment-cream -0.43 (95% confidence interval -1.34 to 0.48) and ointment-gel -0.18 (95% confidence interval -1.11 to 0.75). There was no effect modification by parent expectation, age, disease severity or the application of UK diagnostic criteria, and no differences between groups in any of the secondary outcomes. Median weekly use of allocated emollient, non-allocated emollient and topical corticosteroids was similar across groups. Overall satisfaction was highest for lotions and gels. There was no difference in the number of adverse reactions and there were no significant adverse events. In the nested qualitative study (n = 44 parents, n = 25 children), opinions about the acceptability of creams and ointments varied most, yet problems with all types were reported. Effectiveness may be favoured over acceptability. Parents preferred pumps and bottles over tubs and reported improved knowledge about, and use of, emollients as a result of taking part in the trial. Limitations Parents and clinicians were unmasked to allocation. The findings may not apply to non-study emollients of the same type or to children from more ethnically diverse backgrounds. Conclusions The four emollient types were equally effective. Satisfaction with the same emollient types varies, with different parents/children favouring different ones. Users need to be able to choose from a range of emollient types to find one that suits them. Future work Future work could focus on how best to support shared decision-making of different emollient types and evaluations of other paraffin-based, non-paraffin and 'novel' emollients.

Abstract
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.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) is an effective treatment for depression. Self-directed online CBT interventions have made CBT more accessible at a lower cost. However, adherence is often poor and, in the absence of therapist support, effects are modest and short-term. Delivering CBT online using instant messaging is clinically and cost-effective; however, most existing platforms are limited to instant messaging sessions, without the support of between-session "homework" activities. The INTERACT intervention integrates online CBT materials and 'high-intensity' therapist-led CBT, delivered remotely in real-time. The INTERACT trial will evaluate this novel integration in terms of clinical and cost-effectiveness, and acceptability to therapists and clients. METHODS Pragmatic, two parallel-group multi-centre individually randomised controlled trial, with 434 patients recruited from primary care practices in Bristol, London and York. Participants with depression will be identified via General Practitioner record searches and direct referrals. INCLUSION CRITERIA aged ≥ 18 years; score ≥ 14 on Beck Depression Inventory (BDI-II); meeting International Classification of Diseases (ICD-10) criteria for depression. EXCLUSION CRITERIA alcohol or substance dependency in the past year; bipolar disorder; schizophrenia; psychosis; dementia; currently under psychiatric care for depression (including those referred but not yet seen); cannot complete questionnaires unaided or requires an interpreter; currently receiving CBT/other psychotherapy; received high-intensity CBT in the past four years; participating in another intervention trial; unwilling/unable to receive CBT via computer/laptop/smartphone. Eligible participants will be randomised to integrated CBT or usual care. Integrated CBT utilises the standard Beckian intervention for depression and comprises nine live therapist-led sessions, with (up to) a further three if clinically appropriate. The first session is 60-90 min via videocall, with subsequent 50-min sessions delivered online, using instant messaging. Participants allocated integrated CBT can access integrated online CBT resources (worksheets/information sheets/videos) within and between sessions. Outcome assessments at 3-, 6-, 9- and 12-month post-randomisation. The primary outcome is the Beck Depression Inventory (BDI-II) score at 6 months (as a continuous variable). A nested qualitative study and health economic evaluation will be conducted. DISCUSSION If clinically and cost-effective, this model of integrated CBT could be introduced into existing psychological services, increasing access to, and equity of, CBT provision. TRIAL REGISTRATION ISRCTN, ISRCTN13112900. Registered on 11/11/2020. Currently recruiting participants. Trial registration data are presented in Table 1.

Abstract
BACKGROUND To our knowledge, there are no trials comparing emollients commonly used for childhood eczema. We aimed to compare the clinical effectiveness and safety of the four main emollient types: lotions, creams, gels, and ointments. METHODS We did a pragmatic, individually randomised, parallel group, phase 4 superiority trial in 77 general practice surgeries in England. Children aged between 6 months and 12 years with eczema (Patient Orientated Eczema Measure [POEM] score >2) were randomly assigned (1:1:1:1; stratified by centre and minimised by baseline POEM score and age, using a web-based system) to lotions, creams, gels, or ointments. Clinicians and parents were unmasked. The initial emollient prescription was for 500 g or 500 mL, to be applied twice daily and as required. Subsequent prescriptions were determined by the family. The primary outcome was parent-reported eczema severity over 16 weeks (weekly POEM), with analysis as randomly assigned regardless of adherence, adjusting for baseline and stratification variables. Safety was assessed in all randomly assigned participants. This trial was registered with the ISRCTN registry, ISRCTN84540529. FINDINGS Between Jan 19, 2018, and Oct 31, 2019, 12 417 children were assessed for eligibility, 550 of whom were randomly assigned to a treatment group (137 to lotion, 140 to cream, 135 to gel, and 138 to ointment). The numbers of participants who contributed at least two POEM scores and were included in the primary analysis were 131 in the lotion group, 137 in the cream group, 130 in the gel group, and 126 in the ointment group. Baseline median age was 4 years (IQR 2-8); 255 (46%) participants were girls, 295 (54%) were boys; 473 (86%) participants were White; and the mean POEM score was 9·3 (SD 5·5). There was no difference in eczema severity between emollient types over 16 weeks (global p value=0·77), with adjusted POEM pairwise differences of: cream versus lotion 0·42 (95% CI -0·48 to 1·32), gel versus lotion 0·17 (-0·75 to 1·09), ointment versus lotion -0·01 (-0·93 to 0·91), gel versus cream -0·25 (-1·15 to 0·65), ointment versus cream -0·43 (-1·34 to 0·48), and ointment versus gel -0·18 (-1·11 to 0·75). This result remained unchanged following multiple imputation, sensitivity, and subgroup analyses. The total number of adverse events did not significantly differ between the treatment groups (lotions 49 [36%], creams 54 [39%], gels 54 [40%], and ointments 48 [35%]; p=0·79), although stinging was less common with ointments (12 [9%] of 138 participants) than lotions (28 [20%] of 137), creams (24 [17%] of 140), or gels (25 [19%] of 135). INTERPRETATION We found no difference in effectiveness between the four main types of emollients for childhood eczema. Users need to be able to choose from a range of emollients to find one that they are more likely to use effectively. FUNDING National Institute for Health and Care Research.

Abstract
BACKGROUND More than a third of the 65,000 people living with kidney failure in the UK attend a dialysis unit 2-5 times a week to have their blood cleaned for 3-5 h. In haemodialysis (HD), toxins are removed by diffusion, which can be enhanced using a high-flux dialyser. This can be augmented with convection, as occurs in haemodiafiltration (HDF), and improved outcomes have been reported in people who are able to achieve high volumes of convection. This study compares the clinical- and cost-effectiveness of high-volume HDF compared with high-flux HD in the treatment of kidney failure. METHODS This is a UK-based, multi-centre, non-blinded randomised controlled trial. Adult patients already receiving HD or HDF will be randomised 1:1 to high-volume HDF (aiming for 21+ L of substitution fluid adjusted for body surface area) or high-flux HD. Exclusion criteria include lack of capacity to consent, life expectancy less than 3 months, on HD/HDF for less than 4 weeks, planned living kidney donor transplant or home dialysis scheduled within 3 months, prior intolerance of HDF and not suitable for high-volume HDF for other clinical reasons. The primary outcome is a composite of non-cancer mortality or hospital admission with a cardiovascular event or infection during follow-up (minimum 32 months, maximum 91 months) determined from routine data. Secondary outcomes include all-cause mortality, cardiovascular- and infection-related morbidity and mortality, health-related quality of life, cost-effectiveness and environmental impact. Baseline data will be collected by research personnel on-site. Follow-up data will be collected by linkage to routine healthcare databases - Hospital Episode Statistics, Civil Registration, Public Health England and the UK Renal Registry (UKRR) in England, and equivalent databases in Scotland and Wales, as necessary - and centrally administered patient-completed questionnaires. In addition, research personnel on-site will monitor for adverse events and collect data on adherence to the protocol (monthly during recruitment and quarterly during follow-up). DISCUSSION This study will provide evidence of the effectiveness and cost-effectiveness of HD as compared to HDF for adults with kidney failure in-centre HD or HDF. It will inform management for this patient group in the UK and internationally. TRIAL REGISTRATION ISRCTN10997319 . Registered on 10 October 2017.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Cohort studies are among the most robust of observational studies but have issues with external validity. This study assesses threats to external validity (generalisability) in the European QUALity (EQUAL) study, a cohort study of people over 65 years 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 (secondary care cohort-SCC) and not (primary care cohort-PCC). Survival, progression to renal replacement therapy (RRT), and hospitalisation were compared. RESULTS The analysis included 250, 633, and 2,464 patients in EQUAL, PCC, and SCC. EQUAL had a higher proportion of men in comparison to PCC and SCC (60.0% vs. 34.8% vs. 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 (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 to SCC (8.1% vs. 2.1%%, p < 0.001). Patients in the PCC and SCC had increased risk of Hospitalisation (incidence rate ratio=1.76 (95% CI 1.27-2.47) & 2.13 (95% CI 1.59-2.86)) and mortality at one year (hazard ratio=3.48 (95% CI 2.1-5.7) & 1.7 (95% CI 1.1-2.7)) compared to 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 applying to local practice.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) can relate to urinary storage or voiding. In men, the prevalence and severity of LUTS increases with age, with a significant impact on quality of life. The majority of men presenting with LUTS are managed by their general practitioner (GP) in the first instance, with conservative therapies recommended as the initial treatment. However, the provision of conservative therapies in primary care is variable and can be time and resource limited. GPs require practical resources to enhance patient engagement with such interventions. TRIUMPH aims to determine whether a standardised and manualised care intervention delivered in primary care achieves superior symptomatic outcome for LUTS versus usual care. METHODS/DESIGN TRIUMPH is a two-arm, cluster randomised controlled trial (RCT) being conducted in 30 National Health Service (NHS) general practices in England. The TRIUMPH intervention comprises a standardised LUTS advice booklet developed for the trial with patient and healthcare professional (HCP) consultation. The booklet is delivered to patients by nurses/healthcare assistants following assessment of their urinary symptoms. Patients are directed to relevant sections of the booklet, providing the manualised element of the intervention. To encourage adherence, HCPs provide follow-up contacts over 12 weeks. Practices are randomised 1:1 to either deliver the TRIUMPH intervention or a usual care pathway. The patient-reported International Prostate Symptom Score (IPSS) at 12 months post consent is the primary outcome. Secondary outcomes include cost-effectiveness, patient-reported outcomes on LUTS, quality of life, and patient and HCP acceptability and experience of the intervention. Primary analyses will be conducted on an intention-to-treat basis. DISCUSSION It is unclear whether conservative therapies for male LUTS are effectively delivered in primary care using current approaches. This can lead to men being inappropriately referred to secondary care or experiencing persistent symptoms. Primary care, therefore, holds the key to effective treatment for these men. The TRIUMPH intervention, through its standardised and manualised approach, has been developed to support GP practices in delivering effective conservative care. This pragmatic, cluster RCT should provide robust evidence in a primary-care setting to inform future guidelines. TRIAL REGISTRATION ISCRTN registry, ID: ISRCTN11669964 . Registered on 12 April 2018.

Abstract
BackgroundChronic obstructive pulmonary disease (COPD) is the commonest respiratory disease in the UK, accounting for 10% of emergency hospital admissions annually. Nearly one-third of patients are re-admitted within 28 days of discharge.ObjectivesThe study aimed to evaluate the effectiveness of introducing standardised packages of care (i.e. care bundles) as a means of improving hospital care and reducing re-admissions for COPD.DesignA mixed-methods evaluation with a controlled before-and-after design.ParticipantsAdults admitted to hospital with an acute exacerbation of COPD in England and Wales.InterventionCOPD care bundles.Main outcome measuresThe primary outcome was re-admission to hospital within 28 days of discharge. The study investigated secondary outcomes including length of stay, total number of bed-days, in-hospital mortality, 90-day mortality, context, process and costs of care, and staff, patient and carer experience.Data sourcesRoutine NHS data, including numbers of COPD admissions and re-admissions, in-hospital mortality and length of stay data, were provided by 31 sites for 12 months before and after the intervention roll-out. Detailed pseudo-anonymised data on care during admission were collected from a subset of 14 sites, in addition to information about delivery of individual components of care collected from random samples of medical records at each location. Six case study sites provided data from interviews, observation and documentary review to explore implementation, engagement and perceived impact on delivery of care.ResultsThere is no evidence that care bundles reduced 28-day re-admission rates for COPD. All-cause re-admission rates, in-hospital mortality, length of stay, total number of bed-days, and re-admission and mortality rates in the 90 days following discharge were similar at implementation and comparator sites, as were resource utilisation, NHS secondary care costs and cost-effectiveness of care. However, the rate of emergency department (ED) attendances decreased more in implementation sites than in comparator sites {implementation: incidence rate ratio (IRR) 0.63 [95% confidence interval (CI) 0.56 to 0.70]; comparator: IRR 1.14 (95% CI 1.04 to 1.26) interactionp < 0.001}. Admission bundles appear to be more complex to implement than discharge bundles, with 3.7% of comparator patients receiving all five admission bundle elements, compared with 7.6% of patients in implementation sites, and 28.3% of patients in implementation sites receiving all five discharge bundle elements, compared with 0.8% of patients in the comparator sites. Although patients and carers were unaware that care was bundled, staff view bundles positively, as they help to standardise working practices, support a clear care pathway for patients, facilitate communication between clinicians and identify post-discharge support.LimitationsThe observational nature of the study design means that secular trends and residual confounding cannot be discounted as potential sources of any observed between-site differences. The availability of data from some sites was suboptimal.ConclusionsCare bundles are valued by health-care professionals, but were challenging to implement and there was a blurring of the distinction between the implementation and comparator groups, which may have contributed to the lack of effect on re-admissions and mortality. Care bundles do appear to be associated with a reduced number of subsequent ED attendances, but care bundles are unlikely to be cost-effective for COPD.Future workA longitudinal study using implementation science methodology could provide more in-depth insights into the implementation of care bundles.Trial registrationCurrent Controlled Trials ISRCTN13022442.FundingThis project was funded by the National Institute for Health Research Health Services and Delivery Research programme and will be published in full inHealth Services and Delivery Research; Vol. 7, No. 21.

Abstract
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.

Abstract
Background
The Cystic Fibrosis (CF) Registry collects clinical data on all patients attending specialist CF centres in the UK. These data have been used to make comparisons between centres on key outcomes such as forced expiratory volume in 1 second (FEV1) using simple rankings, which promote the assumption that those with the highest measures provide ‘better’ care.
Objectives
To explore whether or not using statistical ‘process control’ charts that move away from league tables and adjusting for case mix (age, where appropriate; sex; CF genotype; pancreatic sufficiency; and socioeconomic status) could identify exceptional CF care services in terms of clinically meaningful outcomes. Then, using insight from patients and clinicians on what structures, processes and policies are necessary for delivering good CF care, to explore whether or not care is associated with observed differences in outcomes.
Design
Cross-sectional analyses.
Setting
Specialist CF centres in the UK.
Participants
Patients aged ≥ 6 years attending specialist CF centres and clinicians at these centres.
Main outcome measures
FEV1% predicted.
Data sources
Annual reviews taken from the UK CF Registry (2007–15).
Results
We studied FEV1 in many different ways and in different periods. In our analyses of both adult and paediatric centres, we observed that some centres showed repeated evidence of ‘special-cause variation’, with mean FEV1 being greater than the mean in some cases and lower than the mean in others. Some of these differences were explained by statistical adjustment for different measures of case mix, such as age, socioeconomic status, genotype and pancreatic sufficiency. After adjustment, there was some remaining evidence of special-cause variation for some centres. Our data at these centres suggest that there may be an association with the use of intravenous antibiotics. Workshops and focus groups with clinicians at paediatric and adult centres identified a number of structures, processes and policies that were felt to be associated with good care. From these, questionnaires for CF centre directors were developed and disseminated. However, the response rate was low, limiting the questionnaires’ use. Focus groups with patients to gain their insights into what is necessary for the delivery of good care identified themes similar to those identified by clinicians, and a patient questionnaire was developed based on these insights.
Limitations
Our data analyses suggest that differences in intravenous antibiotic usage may be associated with centre-level outcomes; this needs to be explored further in partnership with the centres. Our survey of centre directors yielded a low response, making it difficult to gain useful knowledge to inform further discussions with sites.
Conclusions
Our findings confirm that the CF Registry can be used to identify differences in clinical outcomes between centres and that case mix might explain some of these differences. As such, adjustment for case mix is essential when trying to understand how and why centres differ from the mean.
Future work
Future work will involve exploring with clinicians how care is delivered so that we can understand associations between care and outcomes. Patients will also be asked for their perspectives on the care they receive.

Abstract
OBJECTIVE To investigate the effectiveness of combining mirtazapine with serotonin-noradrenaline reuptake inhibitor (SNRI) or selective serotonin reuptake inhibitor (SSRI) antidepressants for treatment resistant depression in primary care. DESIGN Two parallel group multicentre phase III randomised placebo controlled trial. SETTING 106 general practices in four UK sites; Bristol, Exeter, Hull, and Keele/North Staffs, August 2013 to October 2015. PARTICIPANTS 480 adults aged 18 or more years who scored 14 or more on the Beck depression inventory, second revision, fulfilled ICD-10 (international classification of diseases, 10th revision) criteria for depression, and had used an SSRI or SNRI for at least six weeks but were still depressed. 241 were randomised to mirtazapine and 239 to placebo, both given in addition to usual SSRI or SNRI treatment. Participants were stratified by centre and minimised by baseline Beck depression inventory score, sex, and current psychological therapy. They were followed up at 12, 24, and 52 weeks. 431 (89.8%) were included in the (primary) 12 week follow-up. MAIN OUTCOME MEASURES Depressive symptoms at 12 weeks after randomisation, measured using the Beck depression inventory II score as a continuous variable. Secondary outcomes included measures of anxiety, quality of life, and adverse effects at 12, 24, and 52 weeks. RESULTS Beck depression inventory II scores at 12 weeks were lower in the mirtazapine group after adjustment for baseline scores and minimisation or stratification variables, although the confidence interval included the null (mean (SD) scores at 12 weeks: 18.0 (12.3) in the mirtazapine group, 19.7 (12.4) in the placebo group; adjusted difference between means -1.83 (95% confidence interval -3.92 to 0.27); P=0.09). Adverse effects were more common in the mirtazapine group and were associated with the participants stopping the trial drug. CONCLUSION This study did not find evidence of a clinically important benefit for mirtazapine in addition to an SSRI or SNRI over placebo in a treatment resistant group of primary care patients with depression. This remains an area of important unmet need where evidence of effective treatment options is limited. TRIAL REGISTRATION Current Controlled Trials ISRCTN06653773.

Abstract
BACKGROUND Exposure to respirable crystalline silica (RCS) causes emphysema, airflow limitation and chronic obstructive pulmonary disease (COPD). Slate miners are exposed to slate dust containing RCS but their COPD risk has not previously been studied. AIMS To study the cumulative effect of mining on lung function and risk of COPD in a cohort of Welsh slate miners and whether these were independent of smoking and pneumoconiosis. METHODS The study was based on a secondary analysis of Medical Research Council (MRC) survey data. COPD was defined as forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) ratio <0.7. We created multivariable models to assess the association between mining and lung function after adjusting for age and smoking status. We used linear regression models for FEV1 and FVC and logistic regression for COPD. RESULTS In the original MRC study, 1255 men participated (726 slate miners, 529 unexposed non-miners). COPD was significantly more common in miners (n = 213, 33%) than non-miners (n = 120, 26%), P < 0.05. There was no statistically significant difference in risk of COPD between miners and non-miners when analysis was limited to non-smokers or those without radiographic evidence of pneumoconiosis. After adjustment for smoking, slate mining was associated with a reduction in %predicted FEV1 [β coefficient = -3.97, 95% confidence interval (CI) -6.65, -1.29] and FVC (β coefficient = -2.32, 95% CI -4.31, -0.33) and increased risk of COPD (odds ratio: 1.38, 95% CI 1.06, 1.81). CONCLUSIONS Slate mining may reduce lung function and increase the incidence of COPD independently of smoking and pneumoconiosis.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Studies of the health effects of traffic interventions are rare. The Oxford Transport Strategy (OTS), implemented in June 1999, involved a wide range of permanent changes designed to reduce congestion in the city centre of Oxford, UK. The impact of the OTS on peak expiratory flow (PEF) and respiratory symptoms among schoolchildren in the city is reported. METHODS A dynamic cohort of 1389 children aged 6-10 years attending first schools in Oxford was studied. Schools were visited 2-3 times a year for 5-day periods between 1998 and 2000. On each day of each visit children had their PEF measured and were asked about their respiratory symptoms. RESULTS Changes in traffic varied across the city. In the whole population, regression analysis of daily PEF adjusting for potential confounders showed statistically significant improvements post-OTS (beta = 5.52 l/min, 95% CI 3.08 to 7.97), but there was no consistent evidence that these improvements varied by changes in traffic exposure. In post-hoc analyses, children currently receiving treatment for asthma tended to experience a greater increase in PEF post-OTS as did children from less affluent homes, although these differences did not reach statistical significance. In each of these groups, greater benefits were observed among those living near roads where traffic levels fell post-OTS. CONCLUSIONS These findings suggest that traffic management may lead to small localised improvements in childhood respiratory health and that such benefits are limited to children with pre-existing respiratory problems and those from less affluent backgrounds.

Abstract
BACKGROUND Patients with occupational asthma, and their medical advisers, need valid information about the prognosis of their disease. METHODS A systematic review of the published literature on the symptomatic and functional outcomes of occupational asthma was carried out after avoidance of exposure to the causative agent. Through a full search of electronic and bibliographic sources, original studies documenting complete recovery from asthma (n = 39,1681 patients) or improvement in non-specific bronchial hyper-responsiveness (NSBHR; n = 28,695 patients) were identified. The median duration of follow-up was 31 (range 6-240) months for studies of symptomatic recovery and 37 (6-240) months for studies of NSBHR. Most studies were of patients recruited from special clinics. RESULTS Reported rates of symptomatic recovery varied from 0% to 100%, with a pooled estimate of 32% (95% CI 26% to 38%). These rates were lower with increasing age (p = 0.019) and among clinic based populations (p = 0.053). Patients with the shortest durations of exposure (< or =76 months) had the highest rate of recovery (36%; 95% CI 25% to 50%), but the effect was not linear. The pooled prevalence of persistent NSBHR at follow-up was 73% (95% CI 66% to 79%). This figure was higher among patients whose disease was due to high-molecular-weight agents (p = 0.006) and, less clearly, those from clinic-based populations (p = 0.561). In between-study comparisons, no clear patterns of improvement relating to total duration of exposure or follow-up were found. From within-study comparisons there was some evidence that a shorter duration of symptoms was associated with a higher rate of symptomatic recovery. CONCLUSION The available data on the prognosis of occupational asthma are insufficiently consistent to allow confident advice to be given to patients with the disease. Clinicians and epidemiologists with an interest in this disease should consider a collaborative and carefully standardised study of the prognosis of occupational asthma.

Abstract
BACKGROUND For many years it has been assumed that the risk of childhood respiratory allergies is related to allergen exposures in early life. There are, however, few prospective data in support. We aimed to examine this relationship in a representative cohort of children born in Ashford, Kent (UK). METHODS 625 children (94% of those eligible) were followed from birth to the age of 5.5 years at which time 552 underwent skin prick testing to extracts of house dust mite and cat fur allergens. Maternal reports of wheeze in the last year were collected by interview. These outcomes were related to individual domestic concentrations of Der p 1 and Fel d I allergens estimated from dust collection at the age of 8 weeks. RESULTS 10% of children were sensitised to house dust mite or cat at age 5.5 years; 7% had atopic wheeze. No significant relationships between allergen exposure and either sensitisation or wheeze were found but, on examination, the exposure-response relationships for both allergens and for each outcome rose steeply at low levels of exposure and were attenuated at high levels of exposure. These patterns were modified by paternal atopy and by birth order. CONCLUSIONS There are no linear relationships between early allergen exposure and the induction of childhood respiratory allergy; rather, the risks of IgE sensitisation and asthma rise at very low levels of exposure and are attenuated thereafter. These patterns are influenced by parental atopy and birth order. These findings suggest important gene-environment interactions in the development of atopy and asthma and imply that reductions in domestic allergen exposure alone are unlikely to have a major impact in decreasing the incidence of these diseases in childhood.

Abstract
BACKGROUND This study was conducted to evaluate surgical outcome and to identify risk factors for hospital mortality and reoperation after repair of complete atrioventricular septal defect. METHODS A total of 147 consecutive children underwent repair between January 1986 and December 1998. Of those, 106 had Down syndrome, 37% had normal chromosomes, and 4 had other syndromes; 108 underwent primary repair, 19 had prior pulmonary artery banding, and 20 had additional tetralogy of Fallot. The median weight at primary repair was 4.5 kg. A two-patch technique was used in 88%. RESULTS The 30-day mortality was 15% (70% confidence interval [CI] 12% to 19%). A double orifice atrioventricular valve was found to be a significant risk factor (p = 0.002), with 6 of 11 patients dying. If double orifice atrioventricular valve patients are excluded, the mortality rate falls to 12% (70% CI 9% to 15%). No difference in mortality was found between Down syndrome and chromosomally normal children but the latter more commonly required reoperation. Chromosomally normal children frequently have a dysplastic common atrioventricular valve (24% versus 3% in Down children, p < 0.001). In a multivariate Cox model including both variables, the presence of a dysplastic atrioventricular valve was a significant risk factor for reoperation. After controlling for the presence of a dysplastic atrioventricular valve, Down syndrome retained a significant protective effect but the upper limit of the confidence interval was close to 1. CONCLUSIONS The presence of a double orifice atrioventricular valve emerged as an unforeseen risk factor for death.

Abstract
BACKGROUND Although many patients with severe emphysema have undergone lung-volume-reduction surgery, the benefits are uncertain. We conducted a randomized, controlled trial of the surgery in patients with emphysema. Patients with isolated bullae were excluded because such patients are known to improve after bullectomy. METHODS Potentially eligible patients were given intensive medical treatment and completed a smoking-cessation program and a six-week outpatient rehabilitation program before random assignment to surgery or continued medical treatment. After 15 patients had been randomized, the entry criteria were modified to exclude patients with a carbon monoxide gas-transfer value less than 30 percent of the predicted value or a shuttle-walking distance of less than 150 m, because of the deaths of 5 such patients (3 treated surgically and 2 treated medically). RESULTS Of the 174 subjects who were initially assessed, 24 were randomly assigned to continued medical treatment and 24 to surgery. At base line in both groups, the median forced expiratory volume in one second (FEV1) was 0.75 liter, and the median shuttle-walking distance was 215 m. Five patients in the surgical group (21 percent) and three patients in the medical group (12 percent) died (P=0.43). After six months, the median FEV1 had increased by 70 ml in the surgical group and decreased by 80 ml in the medical group (P=0.02). The median shuttle-walking distance increased by 50 m in the surgical group and decreased by 20 m in the medical group (P=0.02). There were similar changes on a quality-of-life scale and similar changes at 12 months of follow-up. Five of the 19 surviving patients in the surgical group had no benefit from the treatment. CONCLUSIONS In selected patients with severe emphysema, lung-volume-reduction surgery can improve FEV1, walking distance, and quality of life. Whether it reduces mortality is uncertain.
