The effects of a video intervention on posthospitalization pulmonary rehabilitation uptake
Rationale: Pulmonary rehabilitation (PR) after hospitalizations for exacerbations of chronic obstructive pulmonary disease (COPD) improves exercise capacity and health-related quality of life and reduces readmissions. However, posthospitalization PR uptake is low. To date, no trials of interventions to increase uptake have been conducted.Objectives: To study the effect of a codesigned education video as an adjunct to usual care on posthospitalization PR uptake.Methods: The present study was an assessor- and statistician-blinded randomized controlled trial with nested, qualitative interviews of participants in the intervention group. Participants hospitalized with COPD exacerbations were assigned 1:1 to receive either usual care (COPD discharge bundle including PR information leaflet) or usual care plus the codesigned education video delivered via a handheld tablet device at discharge. Randomization used minimization to balance age, sex, FEV1 % predicted, frailty, transport availability, and previous PR experience.Measurements and Main Results: The primary outcome was PR uptake within 28 days of hospital discharge. A total of 200 patients were recruited, and 196 were randomized (51% female, median FEV1% predicted, 36 [interquartile range, 27-48]). PR uptake was 41% and 34% in the usual care and intervention groups, respectively (Pā=ā0.37), with no differences in secondary (PR referral and completion) or safety (readmissions and death) endpoints. A total of 6 of the 15 participants interviewed could not recall receiving the video.Conclusions: A codesigned education video delivered at hospital discharge did not improve posthospitalization PR uptake, referral, or completion

Muscle-specific microRNAs and serum response factor (SRF) are important regulators of muscle phenotype that contribute to a feedback system to regulate muscle gene expression. The role of these factors in the skeletal muscle dysfunction that accompanies COPD is unknown. METHODS: 31 patients with COPD and 14 healthy age-matched controls underwent lung and quadriceps function assessments, measurement of daily activity and a percutaneous quadriceps muscle biopsy. The expression of muscle-specific microRNAs, myosin heavy chains and components of the serum response factor signalling pathway were determined by qPCR. RESULTS: A reduction in expression of miR-1 (2.5-fold, p=0.01) and the myocardin-related transcription factors (MRTFs) A and B was observed in patients compared with controls (MRTF-A mRNA: twofold, p=0.028; MRTF-B mRNA: fourfold, p=0.011). miR-1 expression was associated with smoking history, lung function, fat-free mass index, 6 min walk distance and percentage of type 1 fibres. miR-133 and miR-206 were negatively correlated with daily physical activity. Insulin-like growth factor 1 mRNA was increased in the patients and miR-1 was negatively correlated with phosphorylation of the kinase Akt. Furthermore, the protein levels of histone deacetylase 4, another miR-1 target, were increased in the patients. CONCLUSIONS: Downregulation of the activity of the MRTF-SRF axis and the expression of muscle-specific microRNAs, particularly miR-1, may contribute to COPD-associated skeletal muscle dysfunction.BBSRC, Wellcome Trust and the National Institute for Health Research (NIHR) Respiratory Biomedical Unit at the Royal Brompton Hospital and Imperial College.

Holistic services for people with advanced disease and chronic or refractory breathlessness: a mixed-methods evidence synthesis
Background : Breathlessness is a common and distressing symptom of many advanced diseases, affecting around 2 million people in the UK. Breathlessness increases with disease progression and often becomes chronic or refractory. Breathlessness-triggered services that integrate holistic assessment and specialist palliative care input as part of a multiprofessional approach have been developed for this group, offering tailored interventions to support self-management and reduce distress. Objectives : The aim was to synthesise evidence on holistic breathlessness services for people with advanced disease and chronic or refractory breathlessness. The objectives were to describe the structure, organisation and delivery of services, determine clinical effectiveness, cost-effectiveness and acceptability, identify predictors of treatment response, and elicit stakeholdersā evidence-based priorities for clinical practice, policy and research. Design : The mixed-methods evidence synthesis comprised three components: (1) a systematic review to determine the clinical effectiveness, cost-effectiveness and acceptability of holistic breathlessness services; (2) a secondary analysis of pooled individual data from three trials to determine predictors of clinical response; and (3) a transparent expert consultation (TEC), comprising a stakeholder workshop and an online consensus survey, to identify stakeholdersā priorities. Results : Thirty-seven papers reporting on 18 holistic breathlessness services were included in the systematic review. Most studies enrolled people with thoracic cancer, were delivered over 4ā6 weeks, and included breathing training, relaxation techniques and psychological support. Meta-analysis demonstrated significant reductions in the Numeric Rating Scale (NRS) distress due to breathlessness, significant reductions in the Hospital Anxiety and Depressions Scale (HADS) depression scores, and non-significant reductions in the Chronic Respiratory Disease Questionnaire (CRQ) mastery and HADS anxiety, favouring the intervention. Recipients valued education, self-management interventions, and expertise of the staff in breathlessness and person-centred care. Evidence for cost-effectiveness was limited and inconclusive. The responder analysis (n = 259) revealed baseline CRQ mastery and NRS distress to be strong predictors of the response to breathlessness services assessed by these same measures, and no significant influence from baseline breathlessness intensity, patient diagnosis, lung function, health status, anxiety or depression. The TEC elicited 34 priorities from stakeholders. Seven priorities received high agreement and consensus, reflecting stakeholdersā (n = 74) views that services should be person-centred and multiprofessional, share their breathlessness management skills with others, and recognise the roles and support needs of informal carers.Ā Limitations : The evidence synthesis draws predominantly from UK services and may not be generalisable to other settings. Some meta-analyses were restricted by reporting biases and statistical heterogeneity.Ā Conclusions : Despite heterogeneity in composition and delivery, holistic breathlessness services are highly valued by recipients and can lead to significant improvements in the distress caused by breathlessness and depression. Outcomes of improved mastery and reduced distress caused by breathlessness are not influenced by patient diagnosis, lung function or health status. Stakeholders highlighted the need for improved access to person-centred, multi professional breathlessness services and support for informal carers.Ā Future work : Our research suggests that key therapeutic components of holistic breathlessness services be considered in clinical practice and models of delivery and educational strategies to address stakeholdersā priorities tested

Holistic services for people with advanced disease and chronic breathlessness:a systematic review and meta-analysis
Background: Breathlessness is a common, distressing symptom in people with advanced disease and a marker of deterioration. Holistic services that draw on integrated palliative care have been developed for this group. This systematic review aimed to examine the outcomes, experiences and therapeutic components of these services. Methods: Systematic review searching nine databases to June 2017 for experimental, qualitative and observational studies. Eligibility and quality were independently assessed by two authors. Data on service models, health and cost outcomes were synthesised, using meta-analyses as indicated. Data on recipient experiences were synthesised thematically and integrated at the level of interpretation and reporting. Results: From 3239 records identified, 37 articles were included representing 18 different services. Most services enrolled people with thoracic cancer, involved palliative care staff and comprised 4-6 contacts over 4-6 weeks. Commonly used interventions included breathing techniques, psychological support and relaxation techniques. Meta-analyses demonstrated reductions in Numeric Rating Scale distress due to breathlessness (n=324; mean difference (MD) '2.30, 95% CI '4.43 to '0.16, p=0.03) and Hospital Anxiety and Depression Scale (HADS) depression scores (n=408, MD '1.67, 95% CI '2.52 to '0.81, p<0.001) favouring the intervention. Statistically non-significant effects were observed for Chronic Respiratory Questionnaire (CRQ) mastery (n=259, MD 0.23, 95% CI '0.10 to 0.55, p=0.17) and HADS anxiety scores (n=552, MD '1.59, 95% CI '3.22 to 0.05, p=0.06). Patients and carers valued tailored education, self-management interventions and expert staff providing person-centred, dignified care. However, there was no observable effect on health status or quality of life, and mixed evidence around physical function. Conclusion: Holistic services for chronic breathlessness can reduce distress in patients with advanced disease and may improve psychological outcomes of anxiety and depression. Therapeutic components of these services should be shared and integrated into clinical practice. Registration number: CRD42017057508
Predicting response to holistic breathlessness services: a pooled analysis of trial data
Background: Holistic breathlessness services have been developed for people with advanced disease and chronic breathlessness, leading to improved psychological aspects of breathlessness and health. The extent to which patient characteristics influence outcomes is unclear.Ā Aim: To identify patient characteristics predicting outcomes of mastery and distress around breathlessness following holistic breathlessness services.Ā Design: Secondary analysis of pooled individual patient data from three clinical trials. Our primary analysis assessed predictors of clinically important improvements in Chronic Respiratory Questionnaire mastery scores (+0.5 point), and our secondary analysis predictors of improvements in Numerical Rating Scale distress due to breathlessness (-1 point). Variables significantly related to improvement in univariate models were considered in separate backwards stepwise logistic regression models.Ā Participants: The dataset comprised 259 participants (118 female; mean (standard deviation) age 69.2(10.6) years) with primary diagnoses of chronic obstructive pulmonary disease (49.8%), cancer (34.7%) and interstitial lung disease (10.4%).Results: Controlling for age, sex, and trial, baseline mastery remained the only significant independent predictor of improvement in mastery (odds ratio 0.57, 95% confidence intervals 0.43 to 0.74; p <0001), and baseline distress remained the only significant predictor of improvement in distress (odds ratio 1.64; 95% confidence intervals 1.35 to 2.03; p<001). Baseline lung function, breathlessness severity, health status, mild anxiety and depression, and diagnosis did not predict outcomes.Ā Conclusions: Outcomes of mastery and distress following holistic breathlessness services are influenced by baseline scores for these variables, and not by diagnosis, lung function, or health status. Stratifying patients by levels of mastery and/or distress appears appropriate for clinical trials and services
A randomized trial to assess the impact of an antithrombotic decision aid in patients with nonvalvular atrial fibrillation: the DAAFI trial protocol [ISRCTN14429643]
BACKGROUND: Decision aids are often advocated as a means to assist patient and health care provider decision making when faced with complicated treatment or screening decisions. Despite an exponential growth in the availability of decision aids in recent years, their impact on long-term treatment decisions and patient adherence is uncertain due to a paucity of rigorous studies. The choice of antithrombotic therapy for nonvalvular atrial fibrillation (NVAF) is one condition for which a trade-off exists between the potential risks and benefits of competing therapies, and the need to involve patients in decision making has been clearly identified. This study will evaluate whether an evidence-based patient decision aid for patients with NVAF can improve the appropriateness of antithrombotic therapy use by patients and their family physicians. DESIGN: A multi-center, two-armed cluster randomized trial based in community family practices in which patients with NVAF will be randomized to decision aid or usual care. Patients will receive one of four decision aids depending on their baseline stroke risk. The primary outcome is the provision of "appropriate antithrombotic therapy" at 3 months to study participants (appropriateness defined as per the 2001 American College of Chest Physicians recommendations for NVAF). In addition, the impact of this decision aid on patient knowledge, decisional conflict, well-being, and adherence will be assessed after 3 months, 6 months, and 12 months
Integrating home-based exercise training with a hospital at home service for patients hospitalised with acute exacerbations of COPD: developing the model using accelerated experience-based co-design. International Journal of COPD
Background : Hospital at home (HaH) schemes allow early discharge of patients hospitalised with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Traditional outpatient pulmonary rehabilitation (PR) following an AECOPD has an established evidence-base, but there are issues with low referral, uptake and completion. One commonly cited barrier to PR post-hospitalisation relates to poor accessibility. To address this, the aim of this project was to enrol service users (patients with COPD and informal carers) and healthcare professionals to co-design a model of care that integrates home-based exercise training within a HaH scheme for patients discharged from hospital following AECOPD. Methods : This accelerated experience-based co-design project included three audio-recorded stakeholder feedback events, using key ātouchpointsā from previous qualitative interviews and a recent systematic review. Audio-recordings were inductively analysed using directed content analysis. An integrated model of care was then developed and finalised through two co-design groups, with the decision-making process facilitated by the tables of changes approach. Results : Seven patients with COPD, two informal carers and nine healthcare professionals (from an existing outpatient PR service and HaH scheme) participated in the stakeholder feedback events. Four key themes were identified: 1) individualisation, 2) progression and transition, 3) continuity between services, and 4) communication between stakeholders. Two patients with COPD, one informal carer and three healthcare professionals participated in the first joint co-design group, with five healthcare professionals attending a second co-design group. These achieved a consensus on the integrated model of care. The agreed model comprised face-to-face supervised, individually tailored home-based exercise training one to three times a week, delivered during HaH scheme visits where possible by a healthcare professional competent to provide both home-based exercise training and usual HaH care. Conclusion : An integrated model of care has been co-designed by patients with COPD, informal carers and healthcare professionals to address low uptake and completion of PR following AECOPD. The co-designed model of care has now been integrated within a well-established HaH scheme
