Supporting self-management for patients with Interstitial Lung Diseases: Utility and acceptability of digital devices.

INTRODUCTION: Patients diagnosed with Interstitial Lung Diseases (ILD) use devices to self-monitor their health and well-being. Little is known about the range of devices, selection, frequency and terms of use and overall utility. We sought to quantify patients' usage and experiences with home digital devices, and further evaluate their perceived utility and barriers to adaptation. METHODS: A team of expert clinicians and patient partners interested in self-management approaches designed a 48-question cross-sectional electronic survey; specifically targeted at individuals diagnosed with ILD. The survey was critically appraised by the interdisciplinary self-management group at Royal Devon University Hospitals NHS Foundation Trust during a 6-month validation process. The survey was open for participation between September 2021 and December 2022, and responses were collected anonymously. Data were analysed descriptively for quantitative aspects and through thematic analysis for qualitative input. RESULTS: 104 patients accessed the survey and 89/104 (86%) reported a diagnosis of lung fibrosis, including 46/89 (52%) idiopathic pulmonary fibrosis (IPF) with 57/89 (64%) of participants diagnosed >3 years and 59/89 (66%) female. 52/65(80%) were in the UK; 33/65 (51%) reported severe breathlessness medical research council MRC grade 3-4 and 32/65 (49%) disclosed co-morbid arthritis or joint problems. Of these, 18/83 (22%) used a hand- held spirometer, with only 6/17 (35%) advised on how to interpret the readings. Pulse oximetry devices were the most frequently used device by 35/71 (49%) and 20/64 (31%) measured their saturations more than once daily. 29/63 (46%) of respondents reported home-monitoring brought reassurance; of these, for 25/63 (40%) a feeling of control. 10/57 (18%) felt it had a negative effect, citing fluctuating readings as causing stress and 'paranoia'. The most likely help-seeking triggers were worsening breathlessness 53/65 (82%) and low oxygen saturation 43/65 (66%). Nurse specialists were the most frequent source of help 24/63 (38%). Conclusion: Patients can learn appropriate technical skills, yet perceptions of home-monitoring are variable; targeted assessment and tailored support is likely to be beneficial.

How do patients and other members of the public engage with the orphan drug development? A narrative qualitative synthesis.

BACKGROUND: The diversity of patient experiences of orphan drug development has until recently been overlooked, with the existing literature reporting the experience of some patients and not others. The current evidence base (the best available current research) is dominated by quantitative surveys and patient reported outcome measures defined by researchers. Where research that uses qualitative methods of data collection and analysis has been conducted, patient experiences have been studied using content analysis and automatic textual analysis, rather than in-depth qualitative analytical methods. Systematic reviews of patient engagement in orphan drug development have also excluded qualitative studies. The aim of this paper is to review qualitative literature about how patients and other members of the public engage with orphan drug development. METHODS: We conducted a systematic search of qualitative papers describing a range of patient engagement practices and experiences were identified and screened. Included papers were appraised using a validated tool (CASP), supplemented by reporting guidance (COREQ), by two independent researchers. RESULTS: 262 papers were identified. Thirteen papers reported a range of methods of qualitative data collection. Many conflated patient and public involvement and engagement (PPIE) with qualitative research. Patients were typically recruited via their physician or patient organisations. We identified an absence of overarching philosophical or methodological frameworks, limited details of informed consent processes, and an absence of recognisable methods of data analysis. Our narrative synthesis suggests that patients and caregivers need to be involved in all aspects of trial design, including the selection of clinical endpoints that capture a wider range of outcomes, the identification of means to widen access to trial participation, the development of patient facing materials to optimise their decision making, and patients included in the dissemination of trial results. CONCLUSIONS: This narrative qualitative synthesis identified the explicit need for methodological rigour in research with patients with rare diseases (e.g. appropriate and innovative use of qualitative methods or PPIE, rather than their conflation); strenuous efforts to capture the perspectives of under-served, under-researched or seldom listened to communities with experience of rare diseases (e.g. creative recruitment and wider adoption of post-colonial practices); and a re-alignment of the research agenda (e.g. the use of co-design to enable patients to set the agenda, rather than respond to what they are being offered).

Patient perspectives on home-spirometry in interstitial lung disease: a qualitative co-designed study.

BACKGROUND: Opportunities for home-monitoring are increasing exponentially. Home- spirometry is reproducible and reliable in interstitial lung disease (ILD), yet patients' experiences are not reported. Given the morbidity and mortality associated with ILDs, maintaining health-related quality-of-life is vital. We report our findings from a codesigned, qualitative study capturing the perspectives and experiences of patients using home-spirometry in a UK regional ILD National Health Service England (NHSE) commissioned service. METHODS: Patients eligible for home-spirometry as routine clinical care, able to give consent and able to access a smart phone were invited to participate. In-depth, semistructured interviews were conducted at serial time points (baseline, 1, 3 and 6 months), recorded, transcribed and analysed thematically. RESULTS: We report on the experiences of 10 recruited patients (8 males; median age 66 years, range 50-82 years; 7 diagnosed with idiopathic pulmonary fibrosis, 3 other ILDs) who generally found spirometry convenient and easy to use, but their relationships with forced vital capacity results were complex. Main themes emerging were: (1) anticipated benefits-to identify change, trigger action and aid understanding of condition; (2) needs-clinical oversight and feedback, understanding of results, ownership, need for data and a need 'to know'; (3) emotional impact-worry, reassurance, ambivalence/conflicting feelings, reminder of health issues, indifference; (4) ease of home-spirometry-simplicity, convenience and (5) difficulties with home-spirometry-technical issues, technique, physical effort. CONCLUSION: Home-spirometry has many benefits, but in view of the potential risks to psychological well-being, must be considered on an individual basis. Informed consent and decision-making are essential and should be ongoing, acknowledging potential limitations as well as benefits. Healthcare support is vital.

Multi-center evaluation of baseline neutrophil-to-lymphocyte (NLR) ratio as an independent predictor of mortality and clinical risk stratifier in idiopathic pulmonary fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal disorder with a variable disease trajectory. The aim of this study was to assess the potential of neutrophil-to-lymphocyte ratio (NLR) to predict outcomes in IPF. Methods: We adopted a two-stage discovery (n = 71) and validation (n = 134) design using patients from the UCL partners (UCLp) cohort. We then combined discovery and validation cohorts and included an additional 794 people with IPF, using real-life data from 5 other UK centers, to give a combined cohort of 999 patients. Data were collected from patients presenting over a 13-year period (2006-2019) with mean follow up of 3.7 years (censoring: 2018-2020). Findings: In the discovery analysis, we showed that high values of NLR (>/ = 2.9 vs < 2.9) were associated with increased risk of mortality in IPF (HR 2.04, 95% CI 1.09-3.81, n = 71, p = 0.025). This was confirmed in the validation (HR 1.91, 95% CI 1.15-3.18, n = 134, p = 0.0114) and combined cohorts (HR 1.65, n = 999, 95% CI 1.39-1.95; p < 0·0001). NLR correlated with GAP stage and GAP index (p < 0.0001). Stratifying patients by NLR category (low/high) showed significant differences in survival for GAP stage 2 (p < 0.0001), however not for GAP stage 1 or 3. In a multivariate analysis, a high NLR was an independent predictor of mortality/progression after adjustment for individual GAP components and steroid/anti-fibrotic use (p < 0·03). Furthermore, incorporation of baseline NLR in a modified GAP-stage/index, GAP-index/stage-plus, refined prognostic ability as measured by concordance (C)-index. Interpretation: We have identified NLR as a widely available test that significantly correlates with lung function, can predict outcomes in IPF and refines cohort staging with GAP. NLR may allow timely prioritisation of at-risk patients, even in the absence of lung function. Funding: Breathing Matters, GSK, CF Trust, BLF-Asthma, MRC, NIHR Alpha-1 Foundation.

Sarcoidosis in the UK: insights from British Thoracic Society registry data.

Introduction: The British Thoracic Society Sarcoidosis Registry allows physicians to record clinical data after gaining written consent from patients. The registry's aim is to phenotype sarcoidosis in the UK. Methods: Between February 2013 and July 2017, demographic details for 308 patients (with complete clinical data for 205 patients) presenting to 24 UK hospitals were recorded. This data was analysed to detail methods of presentation, diagnosis and management. Results: Fatigue was a significant complaint, affecting 30% of all patients. The most prevalent CT findings were nodules (in 77% of cases) with traction bronchiectasis (11%), distortion (9%) and ground glass (5%) less prominent. Of 205 patients with complete clinical data, only 64% had a diagnostic tissue biopsy. 35% of all patients underwent endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA) with 15% having a transbronchial biopsy. Use of EBUS-TBNA showed an overall increase over time, from 28% of all patients in 2013 to 43% in 2016. The most common steroid sparing treatment was methotrexate, but 42% of patients were not initiated on any pharmacological treatment at the time of inclusion. Discussion: Fatigue was common and has shown association with poor quality of life. We therefore suggest using a fatigue questionnaire as part of all new patient assessments. It may be that EBUS-TBNA should be reserved for cases of stage I or II disease where there is a reported higher yield than using transbronchial biopsy alone. Bronchoalveolar lavage was not widely used in our data, but it is generally a safe and useful adjunct and should be used more widely.

Contemporary challenges for specialist nursing in interstitial lung disease.

The role of clinical nurse specialists (CNSs) in interstitial lung disease (ILD) is evolving in response to clinical guidelines and the growth of clinical research. The role is well established in the UK, although more ILD posts are needed to ensure supply meets clinical demand. This phenomenon is also happening across Europe. An appreciation of the similarities and differences between CNS and advanced nurse practitioners is important given the challenges in defining, developing and supporting this nursing specialisation. Globally, different models exist. In some countries charitable organisations take a leading role in supporting patients. Many European centres look to the National Institute for Health and Care Excellence guidelines and quality standards as a template to develop and evaluate the role of the ILD CNS. We present a UK perspective in the context of a government subsidised healthcare system to promote professional discussion and debate regarding the future of nursing practice in the ILD specialty. KEY POINTS: ILDs are often complex and associated with significant mortality, morbidity and co-morbid conditions that require a technical healthcare skill setThere is worldwide shortage of nurses, low retention rates and retirement of many skilled nursesCollaboration across the ILD interdisciplinary community is needed to safeguard the future of our professions and high-quality patient careThe ILD interdisciplinary and nurse network has identified key priorities to help secure the future of the ILD clinical and academic nurse specialism. EDUCATIONAL AIMS: To explain the similarities and differences between clinical nurse specialists (CNSs) and advanced nurse practitioners (ANPs) in the context of ILD specialismTo review contemporary nursing specialism in the UK's government subsidised healthcare systemTo stimulate discussion and debate across the European/international respiratory community regarding the clinical and academic development of the ILD CNSTo identify key priorities that will support collaboration across the ILD interdisciplinary workforce in clinical practice and research.

The incidence of work-related illness in the UK health and social work sector: The Health and Occupation Reporting network 2002-2003.

BACKGROUND: In the United Kingdom, The Health and Occupation Reporting network (THOR) collects incidence data on work-related illness. THOR data show that the health and social work sector generates a high proportion of case reports. This study analyses the most recent data for the health and social work sector, from 2002 to 2003. METHODS: Cases returned to the Occupational Physicians Reporting Activity (OPRA) scheme and three other specialist schemes (Surveillance of Occupational Stress and Mental Illness, Musculoskeletal Occupational Surveillance Scheme and occupational skin surveillance) were analysed. Estimates of incidence rates for stress-related illness, musculoskeletal disorders and skin disease were calculated using two denominators. RESULTS: In this period, 23% (11,016/47,437) of all estimated cases in THOR were in health and social work sector employees. In OPRA, in the health and social work sector, annual average incidence rates per 100,000 calculated using Labour Force Survey (LFS) data as the denominator were 51.2 for mental illness, 35.9 for musculoskeletal disorders and 10.4 for skin disease; using McDonald's data as the denominator the corresponding rates were 119.5, 83.7 and 24.3. In the specialist THOR schemes, annual average incidence rates per 100,000 using LFS data as the denominator were 18.4 (mental illness), 6.1 (musculoskeletal disorders) and 15.3 (skin disease). CONCLUSIONS: Our results highlight the importance of collecting information on incident cases and denominators, to allow calculation of occupational disease rates. The higher incidence of mental illness (compared with musculoskeletal and skin disorders) in this employment sector merits further investigation.
