Understanding facilitators and barriers to oxygen therapy for patients with interstitial lung disease.
Interstitial lung disease (ILD) is comprised of a heterogeneous group of pulmonary diseases. Oxygen therapy is used in patients with advanced lung disease; however, there are challenges associated with initiation of oxygen therapy specific to individuals with ILD. The key objectives of this study were to create a common understanding of the facilitators and barriers to oxygen therapy for patients with ILD, and healthcare professionals (HCP) caring for patients with ILD. This qualitative study included 1 hour semistructured focus groups/interviews. An iterative and concurrent process was used for data collection and analysis to allow for supplementary development of themes and concepts generated. Data analysis used a three-phase approach: coding, categorising and development of themes. A total of 20 patients and/or caregivers and 31 HCP took part in 34 focus groups/interviews held over 3 months (November 2022-January 2023). Facilitators to oxygen therapy were identified including support from HCP and support groups, the perseverance and self-advocacy of patients, a straightforward administrative process and vendors/private industry that expedite access to oxygen therapy. There were also several barriers to accessing oxygen therapy for patients with ILD. The themes identified include rural disparity, testing requirements and qualifying for funding and the need for ILD-specific evidence base for oxygen therapy. Further research is needed to facilitate development of specific exertional oxygen criteria for patients with ILD, to create supports for oxygen use and monitoring and to enable providers to tailor therapy to patients. Oxygen therapy education for ILD should address the benefits and risks of oxygen therapy.

Thoughtful prescription of inhaled medication has the potential to reduce inhaler-related greenhouse gas emissions by 85.
Both physicians and patients are increasingly aware of the environmental impacts of medication. The shift of treatment paradigm towards MART-treatment (Maintenance and Reliever Therapy) in asthma affects the treatment-related emissions. The carbon footprint of inhaled medication is also tied to the type of the device used. Today the most commonly used propellant-containing pressurised metered-dose inhalers (pMDIs) have a carbon footprint typically 20-40-fold higher than propellant-free dry powder inhalers (DPIs) and soft mist inhalers. We analysed the carbon footprint of inhaled medications in Europe using published life cycle analyses of marketed inhalers and comprehensive 2020 European sales data. In addition, we give an estimate on treatment-related emissions of different treatment regimens on Global Initiative for Asthma (GINA) step 2. There is potential to reduce the carbon footprint of inhaled medications by 85% if DPIs are preferred over pMDIs. Emissions from pMDIs in the EU were estimated to be 4.0 megatons of carbon dioxide equivalent (MT CO2e) and this could be reduced to 0.6 MT CO2e if DPIs were used instead. In the treatment of moderate asthma with DPI, an as-needed combination of inhaled corticosteroid and long-acting beta-agonist in a single inhaler had a substantially lower annual carbon footprint (0.8 kg CO2e) than the more traditional maintenance therapy with an inhaled corticosteroid alone with as-needed short-acting beta-agonist (2.9 kg CO2e). There has been an urgent call for healthcare to reduce its carbon footprint for appropriate patients with asthma and chronic obstructive pulmonary disease (COPD), changing to non-propellant inhalers can reduce the carbon footprint of their treatment by almost 20-fold.

Patient pathways for four major chronic respiratory diseases in England between 2008 and 2021.
Not all chronic diseases have clear pathways and time targets for diagnosis. We explored pathways and timings for four major chronic respiratory diseases in England. Using deidentified electronic healthcare records from Clinical Practice Research Datalink Aurum linked to Hospital Episode Statistics, we derived cohorts of patients diagnosed with asthma, chronic obstructive pulmonary disease (COPD), ILD or bronchiectasis at three time periods (2008/2009, 2018/2019 and 2020/2021). We followed people 2 years before and 2 years after diagnosis, calculating the proportion of people who presented with symptoms, underwent diagnostic tests, were treated and consulted healthcare (primary or secondary) and calculated time intervals between events. We repeated analyses by socioeconomic status and geographical region. We descriptively studied patient pathways for 429 619 individuals across all time frames and diseases. Most people (>87%) had first evidence of diagnosis in primary care. The proportion of people reporting symptoms prior to diagnosis was similar for asthma, COPD and ILD (41.0%-57.9%) and higher in bronchiectasis (67.9%-71.8%). The proportion undergoing diagnostic tests was high for COPD and bronchiectasis (77.6%-89.2%) and lower for asthma (14%-32.7%) and ILD (2.6%-3.3%). The proportion of people undergoing diagnostic tests decreased in 2020/2021 for all diseases, mostly COPD. Time (months) (median (IQR)) between symptoms and diagnosis, averaged over three time periods, was lowest in asthma (~7.5 (1.3-16.0)), followed by COPD (~8.6 (1.8-17.2)), ILD (~10.1 (3.6-18.0)) and bronchiectasis (~13.5 (5.9-19.8)). Time from symptoms to diagnosis increased by ~2 months in asthma and COPD over the three time periods. Although most patients were symptomatically treated prior to diagnosis, time between diagnosis and postdiagnostic treatment was around 4 months for ILD, 3 months for bronchiectasis and instantaneous for asthma and COPD. Socioeconomic status and regional trends showed little disparity. Current pathways demonstrate missed opportunities to diagnose and manage disease and to improve disease coding.

Relationship between continuity of primary care and hospitalisation for patients with COPD: population-based cohort study from South Korea.
The existing evidence for the impacts of continuity of care (COC) in patients with chronic obstructive pulmonary disease (COPD) is low to moderate. This study aimed to investigate the associations between relational COC within primary care and COPD-related hospitalisations using a robust methodology. Population-based cohort study. National Health Insurance Service database, South Korea. 92 977 adults (≥40 years) with COPD newly diagnosed between 2015 and 2016 were included. The propensity score (PS) matching approach was used. PSs were calculated from a multivariable logistic regression that included eight baseline characteristics. COC within primary care. The primary outcome was the incidence of COPD-related hospitalisations. Cox proportional hazard models were used to estimate HRs and 95% CIs. Out of 92 977 patients, 66 677 of whom were cared for continuously by primary doctors (the continuity group), while 26 300 were not (the non-continuity group). During a 4-year follow-up period, 2094 patients (2.25%) were hospitalised; 874 (1.31%) from the continuity group and 1220 (4.64%) from the non-continuity group. After adjusting for confounding covariates, patients in the non-continuity group exhibited a significantly higher risk of hospital admission (adjusted HR (aHR) 2.43 (95% CI 2.22 to 2.66)). This risk was marginally reduced to 2.21 (95% CI 1.99 to 2.46) after PS matching. The risk of emergency department (ED) visits, systemic corticosteroid use and costs were higher for patients in the non-continuity group (aHR 2.32 (95% CI 2.04 to 2.63), adjusted OR 1.25 (95% CI 1.19 to 1.31) and expβ=1.89 (95% CI 1.82 to 1.97), respectively). These findings remained consistent across the PS-matched cohort, as well as in the sensitivity and subgroup analyses. In patients with COPD aged over 40, increased continuity of primary care was found to be associated with less hospitalisation, fewer ED visits and lower healthcare expenditure.

Assessing the health impacts of parenthood on people with cystic fibrosis: the HOPeCF prospective cohort protocol.
People with cystic fibrosis (CF) are living longer and healthier lives with a growing number considering and pursuing parenthood. The decision of whether to become a parent is complex for people with CF, and CF is a major factor in reproductive decision-making. Unfortunately, in people with CF who become parents, there are no prospective studies of disease trajectory, no data on the impact of parenthood on mental health, disease self-management, or quality of life, and no research regarding non-genetic parenthood. Health Outcomes of Parents with CF (HOPeCF) is a prospective, multicentre observational cohort study which will enrol 146 new parents with CF of children less than 5 years of age. The primary aim of this 60-month study is to assess the rate of lung function decline as impacted by mental health, parental stress and responsibility, and the use of CF transmembrane conductance regulator modulators. In addition, we will conduct dyadic interviews with a subset of study participants and their key supports (partner/family/friend) to inform future interventions. This longitudinal, observational multicentre study is a necessary and timely step in understanding parental health outcomes in CF and will provide data essential for care guidance to people with CF, their partners, and healthcare providers. The University of Pittsburgh Institutional Review Board approved this study (STUDY23080161). As people with a variety of paediatric-onset chronic diseases are living longer and considering parenthood, these results may have widespread applicability and will be distributed at international meetings and submitted to peer-reviewed journals.
