Impact of omitting annual reviews for COPD on patient reported care quality- outcomes from the Asthma+Lung COPD patient passport.

BACKGROUND: Regular clinical reviews of people with COPD provide an opportunity to optimise management and are recommended in national and international guidelines. However, there are limited data about the relationship between having an annual review and other aspects of care quality, which might influence decision-making by healthcare professionals and commissioners. METHOD: Using data from 74 827 people with COPD completing the Asthma+Lung UK COPD Patient Passport, between 2014 and 2022, we conducted adjusted logistic regression (adjusting for year) and compared receipt of key items of care between those reporting that they had had an annual review (65.3%) and those who did not (34.7%). To further capture patient experience, we also analysed 4228 free-text responses to the 2021 Asthma+Lung UK annual COPD survey to the question 'What is the one thing that could improve your COPD care?' RESULTS: We found that the absence of an annual review was associated with significantly worse COPD care across all domains studied; in particular, inhaler training (yes: 80.8% vs no: 38.4%, adjusted OR (AOR): 8.18, 95% CI (7.89 to 8.47), having a written care plan (89.6% vs 56.9%, AOR 6.68 (95% CI 6.35 to 7.05) and medication knowledge (72.6% vs 33.6%, AOR 5.73 (95% CI 5.51 to 5.96). Thematic analysis of the 2021 COPD survey responses identified three areas to improve care: (1) access and support from healthcare services, (2) improved treatment effectiveness and (3) interaction between COPD and the social environment. DISCUSSION: Failure to deliver annual COPD reviews is associated with worse patient-reported experience of care quality. In parallel, people with COPD express a desire for greater support and access to healthcare services.

Smoking and socioeconomic factors linked to acute exacerbations of COPD: analysis from an Asthma + Lung UK survey.

BACKGROUND: Understanding the factors driving acute exacerbations of chronic obstructive pulmonary disease (COPD) is key to reducing their impact on human health and well-being. METHODS: 5997 people with COPD, mean 66 years, 64% female, completed an online survey between December 2020 and May 2021 about living with COPD, developed by the charity Asthma + Lung UK. RESULTS: The 3731 (62.2%) survey participants reporting frequent (≥2/year) exacerbations were more likely to smoke (adjusted OR (AOR) 1.70, 95% CI 1.470 to 1.98), have lower annual household income (≤£20 000 (AOR 1.72, 95% CI 1.36 to 2.17), live in a cold and damp home (AOR 1.78, 95% CI 1.50 to 2.11) and report previous occupational exposure to dust, fumes and chemicals. Smokers were more likely to report attending hospital to manage their most recent acute exacerbation of COPD compared with ex-smokers (AOR 1.25, 95% CI 0.99 to 1.59). DISCUSSION: Strategies to improve COPD outcomes must address issues of deprivation and social justice.

Immediate smoking cessation support versus usual care in smokers attending a targeted lung health check: the QuLIT trial.

OBJECTIVES: Lung cancer screening programmes offer an opportunity to address tobacco dependence in current smokers. The effectiveness of different approaches to smoking cessation in this context has not yet been established. We investigated if immediate smoking cessation support, including pharmacotherapy, offered as part of a lung cancer screening programme, increases quit rates compared to usual care (Very Brief Advice to quit and signposting to smoking cessation services). MATERIALS AND METHODS: We conducted a single-blind randomised controlled trial of current smokers aged 55-75 years attending a Targeted Lung Health Check. On randomly allocated days smokers received either (1) immediate support from a trained smoking cessation counsellor with appropriate pharmacotherapy or (2) usual care. The primary outcome was self-reported quit rate at 3 months. We performed thematic analysis of participant interview responses. RESULTS: Of 412 people attending between January and March 2020, 115 (27.9%) were current smokers; 46% female, mean (SD) 62.4 (5.3) years. Follow-up data were available for 84 smokers. At 3 months, quit rates in the intervention group were higher 14/48 (29.2%) vs 4/36 (11%) (χ2 3.98, p=0.04). Participant interviews revealed four smoking-cessation related themes: (1) stress and anxiety, (2) impact of the COVID-19 pandemic, (3) CT scans influencing desire to quit and (4) individual beliefs about stopping smoking. CONCLUSION: The provision of immediate smoking cessation support is associated with a substantial increase in quit rates at 3 months. Further research is needed to investigate longer-term outcomes and to refine future service delivery. TRIAL REGISTRATION NUMBER: ISRCTN12455871.

Impact of COVID-19 on people with asthma: a mixed methods analysis from a UK wide survey.

INTRODUCTION: The impact of acute COVID-19 on people with asthma appears complex, being moderated by multiple interacting disease-specific, demographic and environmental factors. Research regarding longer-term effects in this group is limited. We aimed to assess impacts of COVID-19 and predictors of persistent symptoms, in people with asthma. METHODS: Using data from an online UK-wide survey of 4500 people with asthma (median age 50-59 years, 81% female), conducted in October 2020, we undertook a mixed methods analysis of the characteristics and experience of those reporting having had COVID-19. RESULTS: The COVID-19 group (n=471, 10.5%) reported increased inhaler use and worse asthma management, compared with those not reporting COVID-19, but did not differ by gender, ethnicity or household income. Among the COVID-19 group, 56.1% reported having long COVID, 20.2% were 'unsure'. Those with long COVID were more likely than those without long COVID to describe: their breathing as worse or much worse after their initial illness (73.7% vs 34.8%, p<0.001), increased inhaler use (67.8% vs 34.8%, p<0.001) and worse or much worse asthma management (59.6% vs 25.6%, p<0.001). Having long COVID was not associated with age, gender, ethnicity, UK nation or household income.Analysis of free text survey responses identified three key themes: (1) variable COVID-19 severity, duration and recovery; (2) symptom overlap and interaction between COVID-19 and asthma; (3) barriers to accessing healthcare. CONCLUSIONS: Persisting symptoms are common in people with asthma following COVID-19. Measures are needed to ensure appropriate healthcare access including clinical evaluation and investigation, to distinguish between COVID-19 symptoms and asthma.

The physiology of singing and implications for 'Singing for Lung Health' as a therapy for individuals with chronic obstructive pulmonary disease.

Singing is an increasingly popular activity for people with chronic obstructive pulmonary disease (COPD). Research to date suggests that 'Singing for Lung Health' may improve various health measures, including health-related quality-of-life. Singing and breathing are closely linked processes affecting one another. In this narrative review, we explore the physiological rationale for 'Singing for Lung Health' as an intervention, focusing on the abnormalities of pulmonary mechanics seen in COPD and how these might be impacted by singing. The potential beneficial physiological mechanisms outlined here require further in-depth evaluation.

Working accuracy of pulse oximetry in COVID-19 patients stepping down from intensive care: a clinical evaluation.

INTRODUCTION: UK guidelines suggest that pulse oximetry, rather than blood gas sampling, is adequate for monitoring of patients with COVID-19 if CO2 retention is not suspected. However, pulse oximetry has impaired accuracy in certain patient groups, and data are lacking on its accuracy in patients with COVID-19 stepping down from intensive care unit (ICU) to non-ICU settings or being transferred to another ICU. METHODS: We assessed the bias, precision and limits of agreement using 90 paired SpO2 and SaO2 from 30 patients (3 paired samples per patient). To assess the agreement between pulse oximetry (SpO2) and arterial blood gas analysis (SaO2) in patients with COVID-19, deemed clinically stable to step down from an ICU to a non-ICU ward, or be transferred to another ICU. This was done to evaluate whether the guidelines were appropriate for our setting. RESULTS: Mean difference between SaO2 and SpO2 (bias) was 0.4%, with an SD of 2.4 (precision). The limits of agreement between SpO2 and SaO2 were as follows: upper limit of 5.2% (95% CI 6.5% to 4.2%) and lower limit of -4.3% (95% CI -3.4% to -5.7%). CONCLUSIONS: In our setting, pulse oximetry showed a level of agreement with SaO2 measurement that was slightly suboptimal, although within acceptable levels for Food and Drug Authority approval, in people with COVID-19 judged clinically ready to step down from ICU to a non-ICU ward, or who were being transferred to another hospital's ICU. In such patients, SpO2 should be interpreted with caution. Arterial blood gas assessment of SaO2 may still be clinically indicated.

Dance for people with chronic respiratory disease: a qualitative study.

OBJECTIVES: To explore the experiences and perceived impact on health and well-being related to participation in a dance group for people with chronic respiratory disease (CRD). DESIGN: An exploratory qualitative study using thematic analysis of semistructured interviews. SETTING: A community dance group in a UK health centre. PARTICIPANTS: Convenience sample of long-term dance group participants. INTERVENTION: Weekly community dance sessions designed for people with breathlessness, lasting 75 min, led by a trained community dance leader. RESULTS: Convenience sample of eight participants, six females, aged 57-87 years (mean 75), with a median 2-year attendance at weekly dance sessions. Long-term attendance was driven by strongly held beliefs regarding the health and well-being benefits of participation. Four key themes were identified: dance as (1) a holistically beneficial activity, with physical and psychosocial health benefits including improved or maintained physical fitness and psychological well-being, and reduced need for healthcare; (2) an integral part of their life; (3) an enjoyable activity; and (4) a source of deep social cohesion. CONCLUSIONS: Dance group participants perceived a broad range of health benefits of relevance to the biopsychosocial impacts of their respiratory disease. The themes identified are useful in the ongoing planning and evaluation of dance as a holistic complex intervention for people with CRD. Further research is required to assess the extent of health impacts identified, and how dance might be most effectively placed as an option in the management of CRD.

Pleural tuberculosis: a key differential diagnosis for pleural thickening, even without obvious risk factors for tuberculosis in a low incidence setting.

We report the case of a 64-year-old woman, presenting with pleuritic chest pain and weight loss. She had a previous history of breast malignancy and no clear risk factors for tuberculosis (TB). Initial investigations showed a right-sided pleural effusion and pleural thickening suggestive of malignancy, which would have been in keeping with the clinical presentation. Initial pleural biopsy showed features suggestive of possible TB infection, though no growth on cultures. A repeat biopsy was negative on initial microscopy, but was culture positive for Mycobacterium tuberculosis, also identifying isoniazid resistance. This case highlights that TB remains an important differential even in the absence of classical risk factors, and illustrates the diagnostic challenges it poses. It also highlights the value of culture positivity in identification of drug resistance and facilitation of appropriate treatment.
