Background: Individuals with Preserved Ratio Impaired Spirometry (PRISm), defined as FEV₁/FVC ≥0.7 and FEV1 <80% predicted, are at higher risk of developing COPD. However, data for Australian adults are limited. We aimed to describe prevalence of PRISm and its relationship with clinical characteristics in Australia. Method: Data from the Burden of Lung Disease (BOLD) Australia study of randomly selected adults aged ≥40 years from six sites was classified into airflow limitation, PRISm, or normal spirometry groups. Demographic, clinical characteristics, and lung function were compared between groups. Results: Of the study sample (n = 3518), 387 (11%) had PRISm, 549 (15.6%) had airflow limitation, and 2582 (73.4%) had normal spirometry. PRISm was more common in Indigenous Australian adults. Adults with PRISm had more frequent respiratory symptoms, more comorbidities, greater health burden and poorer quality of life than those with normal spirometry. Pre- and post-bronchodilator FEV₁ and FVC were lower in adults with PRISm than those with airflow limitation. Adults with PRISm were less likely to use respiratory medicine than those with airflow limitation (OR = 0.56, 95% CI 0.38-0.81). Conclusions: PRISm was present in 11% of adults in this study and they had similar respiratory symptoms and health burden as adults with airflow limitation.

Objectives: Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disease with high morbidity and mortality. COPD guidelines (CPG) are greatly underutilized and studies attempting to improve this practice gap have yielded inconsistent results. We hypothesize that using implementation science can provide a detailed understanding of these practice gaps and the reasons behind them. Methods: Since primary care (PC) manages the bulk of COPD patients, in this pilot study, we use principles of implementation science to systematically explore the reasons for this implementation gap in a PC setting. We used the Consolidated Framework of Implementation Science (CFIR), a determinant framework to design semi-structured interview guides to conduct multistakeholder interviews to explore the barriers and facilitators to four key COPD-CPG with known poor uptake: inhaler education, spirometry, pulmonary rehabilitation and COPD-specific patient education from patient and provider perspectives. Qualitative analysis was performed using rapid analysis. Results: Seventeen respondents including both, patients and providers were interviewed. All these COPD-CPG were rated as 'highly important' suggesting that perceived importance alone is insufficient to bridge gaps in uptake. Respondents were least familiar with pulmonary rehabilitation. Physician time constraint was a significant reported barrier. There exist multilevel contextual barriers to each of these COPD-CPG. Discussion: To increase uptake of COPD guidelines, implementation efforts that address multilevel barriers and promote collaborative care by use of non-physician resources are likely to have higher buy-in and greater chances for success.

To evaluate the impact of participant-selected music listening as an adjunct to pulmonary rehabilitation (PR) in people with COPD. Adults with COPD referred to PR were randomly assigned to participant-selected music listening (intervention group, [IG]) or usual care (control group [CG]) during an 8-weeks PR program. Prior to training, the IG completed an interview with a registered music therapist to identify music preferences. IG participants listened to an individualised playlist; CG participants had usual care. Primary outcomes included end-6-min walk test symptoms (dyspnoea and exertion) and dyspnoea (Multidimensional Dyspnoea Profile [MDP]), measured pre and post PR and 6-months follow-up. 58 participants, FEV1 52.4 (25.9)% pd) were recruited. There were no between-group differences following the intervention (p > .05 for all outcomes at all time points). Within-group differences following PR were significant for MDP sensory quality: IG mean difference [95% CI] -2.2 [-3.3 to -1.2]; CG -1.5 [-2.5 to -0.5] points; MDP emotional response: IG -3.2 [-4.2 to -2.3]; CG -2.2 [-3.2 to -1.3] points). Participant-selected music listening during PR offered no greater benefit to symptoms of dyspnoea or exertion compared to usual care. With the study limited by COVID-19 restrictions, the role of this adjunct remains to be clarified.

Objectives: Pulmonary Rehabilitation (PR) is a high-impact intervention for individuals with idiopathic pulmonary fibrosis (IPF) but access is limited in India. PR barriers include distance to travel, lack of service provision and lack of healthcare professionals to deliver PR, thus it is disproportionate to the immense burden of IPF in India. We explored the lived experiences of people living with IPF, family caregivers (CGs) and healthcare workers (HCWs) as well as their views towards home-based PR (HBPR) in Delhi, India.

Methods: A qualitative study using semi-structured interviews with individuals with IPF (n = 20), CGs (n = 10) and HCWs (n = 10) was conducted. Data were analysed using codebook thematic analysis.

Results: Three major themes were generated: (i) Health impact, which included pathophysiological changes, range of symptoms experienced, disease consequences and impact of comorbidities; (ii) Disease management, which described strategies to control the progression and overall management of IPF, such as medications and exercises; (iii) Mode of Pulmonary Rehabilitation, which described perceptions regarding HBPR, comparisons with centre-based programmes, and how HBPR may fit as part of a menu of PR delivery options.

Conclusion: People living with IPF, family caregivers and healthcare workers were positive about the potential implementation of HBPR and suggested the development of a paper-based manual to facilitate HBPR over digital/online approaches. The content of HBPR should be sensitive to the additional impact of non-IPF health issues and challenges of reduced interactions with healthcare professionals.

Background: Previous studies have focused on demographic factors that might predict non-completion of pulmonary rehabilitation (PR). We aimed to identify key modifiable factors that promote completion of PR. Methods: A mixed methods survey was offered to participants completing a discharge assessment following PR. Descriptive statistics and inductive thematic analysis were used to analyse the survey responses, with investigator triangulation. Results: 62 of 187 (33%) patients attending a PR discharge assessment between November 2022 and April 2023 returned the anonymised survey. Desire to improve health and wellbeing was the main reason for both initially committing to a course and for continuing with PR past transient thoughts of leaving. The positive impact of staff was the second most common reason. The enjoyment of the PR programme, being held accountable to attend classes, and the importance of other group members were other key themes identified. Conclusions: In conclusion, our findings suggest PR services need to implement strategies which ensure regular promotion and reinforcement of the health benefits of PR as well as implementation of PR modalities which best monopolise on the positive impact skilled staff have on motivating patients to complete PR.

Introduction: Multiple studies focusing on chronic lung diseases (i.e. COPD), have indicated that the quality of life (QoL) can be impacted by disease-related fears. In the context of Interstitial Lung Diseases (ILD), however, these have never been systematically examined. Therefore, the aim of the present study was to develop and evaluate an appropriate measuring tool, and to investigate the influence of disease-related anxieties on QoL in ILD.

Method: N = 166 ILD patients participated in the study and completed an itempool on disease-related fears, based on the COPD-Anxiety-Questionnaire (CAF-R) and expert assessments. Further, demographic and psychological variables were assessed (anxiety: GAD-7, QoL: K-BILD; Beliefs about Health: KKG). Psychometric properties were analyzed (factor structure, reliability, validity). Regression analyses were used to calculate the differential predictive power of disease-related anxieties on QoL.

Results: The factor structure was confirmed (Scales: Fear-of-Dependence-and-Progression, Fear-of-Social-Exclusion-and-Isolation, Fear-of-Physical-Activity, Fear-of-Dyspnea, and Sleep-related- Complaints). The Scales showed satisfying reliabilities (α = 0.68 to 0.89) and good validity. Disease-related anxieties proved to be differential predictors for different scales of the K-BILD (ß = -0.15 to ß = -0.58, all ps < .01).

Conclusions: The ILD-Anxiety-Questionnaire (IAQ) is an easy-to-use, valid measurement tool for assessing disease-related anxieties. These vary in their impact on different aspects of QoL. Therefore, it might aid in specifying the indication for potential psychological supplementary interventions. Additional long-term studies are required to investigate how specific anxieties affect both overall and condition-specific QoL in diverse situations.

Objectives: Chronic respiratory diseases (CRDs) are a burden on both individuals and society. While previous literature has highlighted the clinical burden and total costs of care, it has not addressed patients' direct payments. This study aimed to estimate the incremental healthcare costs associated with patients with CRDs, specifically out-of-pocket (OOP) costs.

Methods: We used survey data from the 2019 Korea Health Panel Survey to estimate the total OOP costs of CRDs by comparing the annual hospitalizations, outpatient visits, emergency room visits, and medications of patients with and without CRDs. Generalized linear regression models controlled for differences in other characteristics between groups.

Results: We identified 222 patients with CRDs, of whom 166 were aged 65 years and older. Compared with the non-CRD group, CRD patients spent more on OOP costs (238.3 USD on average). Incremental costs were driven by outpatient visits and medications, which are subject to a coinsurance of 30% or more and may include items not covered by public insurance. Moreover, CRD patients aged 50-64 years incurred the highest incremental costs.

Discussion: The financial burden associated with CRDs is significant, and outpatient visits and medications constitute the largest components of OOP spending. Policymakers should introduce appropriate strategies to reduce CRD-associated burdens.

This state-of-the-art review provides an overview of the history of home mechanical ventilation (HMV), including early descriptions of mechanical ventilation from ancient and Renaissance perspectives and the mass development of ventilators designed for long-term use during the poliomyelitis epidemic. Seminal data from key clinical trials supports the application of HMV in certain patients with chronic obstructive pulmonary disease, neuromuscular disease and obesity-related respiratory failure. Innovative engineering coupled with refined physiological understanding now permits widespread delivery of home mechanical ventilation to a global population, using portable devices with advanced ventilatory modes and telemonitoring capabilities. Exponential growth in digital technology continues, and ongoing research is needed to understand how to harness clinical and physiological data to benefit patients and healthcare services in a clinically- and cost-effective manner.
