Patient information, education and self-management in bronchiectasis: facilitating improvements to optimise health outcomes

Background: Bronchiectasis is an incurable lung disease characterised by irreversible airway dilatation. It causes symptoms including chronic productive cough, dyspnoea, and recurrent respiratory infections often requiring hospital admission. Fatigue and reductions in quality of life are also reported in bronchiectasis. Patients often require multi-modal treatments that can be burdensome, leading to issues with adherence. In this article we review the provision of, and requirement for, education and information in bronchiectasis. Discussion: To date, little research has been undertaken to improve self-management in bronchiectasis in comparison to other chronic conditions, such as COPD, for which there has been a wealth of recent developments. Qualitative work has begun to establish that information deficit is one of the potential barriers to self-management, and that patients feel having credible information is fundamental when learning to live with and manage bronchiectasis. Emerging research offers some insights into ways of improving treatment adherence and approaches to self-management education; highlighting ways of addressing the specific unmet information needs of patients and their families who are living with bronchiectasis. Conclusions: We propose non-pharmacological recommendations to optimise patient self-management and symptom recognition; with the aim of facilitating measurable improvements in health outcomes for patients with bronchiectasis

Evaluation of a novel information resource for patients with bronchiectasis: study protocol for a randomised controlled trial

Background: There is currently little patient information on bronchiectasis, a chronic lung disease with rising prevalence. Previous work shows that patients and their families want more information, which could potentially improve their understanding and self-management. Using interviews and focus groups, we have co-developed a novel patient and carer information resource, aiming to meet their identified needs. The aims and objectives are: 1. To assess the potential impact of the information resource 2. To evaluate and refine the intervention 3. To establish the feasibility of carrying out a multi-centre randomised controlled trial to determine its effect on understanding, self-management and health outcomes. Methods/design: This is a feasibility study, with a single-centre, randomised controlled trial design, comparing use of a novel patient information resource to usual care in bronchiectasis. Additionally, patients and carers will be invited to focus groups to discuss their views on both the intervention itself and the trial process. The study duration for each participant will be 3 months from the study entry date. A total of 70 patients will be recruited to the study, and a minimum of 30 will be randomised to each arm. Ten participants (and their carers if applicable) will be invited to attend focus groups on completion of the study visits. Participants will be adults with bronchiectasis diagnosed as per national bronchiectasis guidelines. Once consented, participants will be randomised to the intervention or control arm using random permuted blocks to ensure treatment group numbers are evenly balanced. Randomisation will be web-based. Those randomised to the intervention will receive the information resource (website and booklet) and instructions on its use. Outcome measures (resource satisfaction, resource use and alternative information seeking, quality of life questionnaires, unscheduled healthcare visits, exacerbation frequency, bronchiectasis knowledge questionnaire and lung function tests) will be recorded at baseline, 2 weeks and 3 months. Discussion: All outcome measures will be used in assessing feasibility and acceptability of a future definitive trial. Feasibility outcomes include recruitment, retention and study scale form completion rates. Focus groups will strengthen qualitative data for resource refinement and to identify participant views on the trial process, which will also inform feasibility assessments. Questionnaires will also be used to evaluate and refine the resource

Critical care admission trends and outcomes in individuals with bronchiectasis in the UK

Background: There are limited data on admission trends and outcomes of individuals with bronchiectasis admitted to intensive care (ICU). Using national critical care data, we analysed admissions to ICU and estimated outcomes in terms of mortality in individuals with bronchiectasis and chronic obstructive pulmonary disease (COPD) admitted to ICU. Methods: Using data from the Intensive Care National Audit and Research Centre, admissions from bronchiectasis and COPD from 1 January 2009 to 31 December 2013 were extracted. Crude admission rates for bronchiectasis and COPD were calculated and Poisson regression was used to estimate unadjusted annual admission rate ratios. We investigated changes to length of stay on ICU, ICU mortality and in-hospital mortality during the study period. We also compared mortality rates in people with bronchiectasis and COPD aged 70 or above. Results: We found an annual increase of 8% (95% Confidence Interval [CI] 2-15) in the number of ICU admissions from bronchiectasis, whilst the yearly increase in ICU admissions from COPD was 1% (95% CI 0.3-2). ICU and in-hospital mortality was higher in individuals with bronchiectasis compared with those with COPD, especially in people aged 70 years or above. Conclusion: Admission to ICU in people with bronchiectasis are uncommon, but are increasing in frequency over time, and carries a substantial mortality rate. This needs to be considered allocating health care resources and planning respiratory services

Phase II study of a neutrophil elastase inhibitor (AZD9668) in patients with bronchiectasis

SummaryNeutrophil elastase (NE) activity is increased in bronchiectasis and may play a role in this condition. We wished to determine the effect of AZD9668, a selective oral inhibitor of NE.Efficacy and safety of AZD9668 60 mg twice daily over 4 weeks were evaluated in a randomised, double-blind, placebo-controlled, parallel-group, Phase II, signal-searching study in patients with bronchiectasis. Outcome measures included: waking and post-waking sputum neutrophil counts; lung function tests; 24-h sputum weight; BronkoTest® diary card data; St George's Respiratory Questionnaire for COPD patients (SGRQ-C); sputum NE activity; inflammatory biomarker levels; desmosine levels; adverse events, safety haematology and biochemistry. AZD9668 levels in plasma and sputum were measured to confirm exposure.Thirty-eight patients were randomised: 16 to placebo and 22 to AZD9668. There was no change in sputum neutrophils with AZD9668. Forced expiratory volume in 1 s improved by 100 mL in the AZD9668 group compared with placebo (p = 0.006). Significant changes (defined a priori as p < 0.1) in favour of AZD9668 were also seen in slow vital capacity, plasma interleukin-8, and post-waking sputum interleukin-6 and Regulated on Activation, Normal T-cell Expressed and Secreted levels. Non-significant changes in favour of AZD9668 were seen in other lung function tests, sputum weight and the SGRQ-C. AZD9668 was well tolerated.In this small signal-searching study, 4 weeks' treatment with AZD9668 improved lung function in patients with bronchiectasis and there were trends for reductions in sputum inflammatory biomarkers. Larger studies of longer duration would be needed to confirm the potential benefits of this agent in bronchiectasis.Registration: NCT00769119

Digital technologies in bronchiectasis physiotherapy services: A survey of patients and physiotherapists in a UK centre

Introduction We aimed to explore how digital technology is currently used, could be used and how services could be improved in order to optimise bronchiectasis physiotherapy care. Methods Online surveys were designed and distributed amongst people with bronchiectasis and physiotherapists in Northern Ireland. Responses to closed and open question formats were collected and analysed. Results The survey was completed by 48 out of 100 physiotherapists (48%) between January 2020 and January 2021 and by 205 out of 398 people with bronchiectasis (52%) between October 2020 and October 2021. 56% of physiotherapists (27 out of 48) reporting using some type of digital technology to facilitate services, whereas 44% (21 out of 48) reported that they had never used a digital technology in this patient group. When physiotherapists were asked whether they would be likely to use certain remote and/or digital options to deliver follow-up care for airway clearance techniques, most (31–38 out of 48; 65–79%) indicated that they would. Regarding patient responses, most reported that they would use telephone consultation (145 out of 199, 73%) and a smaller proportion were likely to use video consultation (64 out of 199, 32%). The most commonly mentioned theme for improvement amongst patients was follow-ups, while improved access, quality of services and treatments were the most commonly mentioned amongst physiotherapists. Conclusion Despite a large proportion of physiotherapists in this survey reporting no current use of digital technology in bronchiectasis physiotherapy care, there was significant interest and willingness to do so, amongst both physiotherapists and patients. This survey highlighted a range of care areas, specifically follow-up visits, where digital methods could be further explored.</p

Anti-bacterial antibody and T cell responses in Bronchiectasis are differentially associated with lung colonization and disease

Background: As a way to determine markers of infection or disease informing disease management, and to reveal disease-associated immune mechanisms, this study sought to measure antibody and T cell responses against key lung pathogens and to relate these to patients’ microbial colonization status, exacerbation history and lung function, in Bronchiectasis (BR) and Chronic Obstructive Pulmonary Disease (COPD). Methods: 119 patients with stable BR, 58 with COPD and 28 healthy volunteers were recruited and spirometry was performed. Bacterial lysates were used to measure specific antibody responses by ELISA and T cells by ELIspot. Cytokine secretion by lysate-stimulated T cells was measured by multiplex cytokine assay whilst activation phenotype was measured by flow cytometry. Results: Typical colonization profiles were observed in BR and COPD, dominated by P.aeruginosa, H.influenzae, S.pneumoniae and M.catarrhalis. Colonization frequency was greater in BR, showing association with increased antibody responses against P.aeruginosa compared to COPD and HV, and with sensitivity of 73% and specificity of 95%. Interferon-gamma T cell responses against P.aeruginosa and S.pneumoniae were reduced in BR and COPD, whilst reactive T cells in BR had similar markers of homing and senescence compared to healthy volunteers. Exacerbation frequency in BR was associated with increased antibodies against P. aeruginosa, M.catarrhalis and S.maltophilia. T cell responses against H.influenzae showed positive correlation with FEV1% (r=0.201, p=0.033) and negative correlation with Bronchiectasis Severity Index (r=-0.287, p=0.0035). Conclusion: Our findings suggest a difference in antibody and T cell immunity in BR, with antibody being a marker of exposure and disease in BR for P.aeruginosa, M.catarrhalis and H.influenzae, and T cells a marker of reduced disease for H.influenzae
