Sex-differences in COPD: from biological mechanisms to therapeutic considerations.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous respiratory condition characterized by symptoms of dyspnea, cough, and sputum production. We review sex-differences in disease mechanisms, structure-function-symptom relationships, responses to therapies, and clinical outcomes in COPD with a specific focus on dyspnea. Females with COPD experience greater dyspnea and higher morbidity compared to males. Imaging studies using chest computed tomography scans have demonstrated that females with COPD tend to have smaller airways than males as well as a lower burden of emphysema. Sex-differences in lung and airway structure lead to critical respiratory mechanical constraints during exercise at a lower absolute ventilation in females compared to males, which is largely explained by sex differences in maximum ventilatory capacity. Females experience similar benefit with respect to inhaled COPD therapies, pulmonary rehabilitation, and smoking cessation compared to males. Ongoing re-assessment of potential sex-differences in COPD may offer insights into the evolution of patterns of care and clinical outcomes in COPD patients over time.

THE LIVED EXPERIENCE OF COPD AND EMOTIONAL DISTRESS IN US VETERANS: A MIXED-METHOD STUDY

Abstract Behavioral interventions targeting low physical activity (PA) and comorbid emotional distress are critically needed to address gaps in the management of chronic obstructive pulmonary disease (COPD). A mixed-methods study was conducted to guide the development of Step-Cognitive Behavioral Therapy (Step-CBT), a virtual behavioral intervention under study integrating PA promotion with CBT for those with COPD. Semi-structured interviews with U.S. Veterans with COPD at the VA Boston Healthcare System explored the lived experience of COPD and emotional distress. Participants completed the Patient Health Questionnaire-9 [PHQ-9], Beck Anxiety Inventory [BAI]), and wore an accelerometer (ActiGraph wGT3X-BT) for 14 days to measure objective PA. Thematic analysis was used to code responses and identify themes. Participants (n=22; 90.9% male, age 68.0±6.0 years; 96% White) were assessed. PHQ-9 indicated moderate depression severity (M=11.3± 5.3) and BAI scores indicated moderate anxiety severity (M=26.5±9.4). Average daily step count was (M=6,611±4,799). In response to questions eliciting participants’ experience of emotional distress, participants described Emotions, Behaviors, and Cognitions associated with distress that interacted with COPD and PA (e.g., “I’ve gotta catch my breath where before I could just do up the yard with no problem… so that gets me depressed”). When asked about engaging in daily PA in the context of emotional distress, three themes emerged: Emotion Regulation and Coping (e.g., healthy behavioral coping, maladaptive coping, etc.), Factors that Motivate (i.e., routine/schedule, etc.), and Social Context. Findings illuminate linkages between emotional distress and PA that will guide the creation of vignette-based treatment modules in the development of Step-CBT.

Clinician's Corner: Counseling Patients with Chronic Obstructive Pulmonary Disease Traveling to High Altitude.

Bloch, Konrad E., Talant M. Sooronbaev, Silvia Ulrich, Mona Lichtblau, and Michael Furian. Clinician's corner: counseling patients with chronic obstructive pulmonary disease traveling to high altitude. High Alt Med Biol. 00:000-000, 2023.-Mountain travel is increasingly popular also among patients with chronic obstructive pulmonary disease (COPD), a highly prevalent condition often associated with cardiovascular and systemic manifestations. Recent studies have shown that nonhypercapnic and only mildly hypoxemic lowlanders with moderate to severe airflow obstruction owing to COPD experience dyspnea, exercise limitation, and sleep disturbances when traveling up to 3,100 m. Altitude-related adverse health effects (ARAHE) in patients with COPD include severe hypoxemia, which may be asymptomatic but expose patients to the risk of excessive systemic and pulmonary hypertension, cardiac arrhythmia, and even myocardial or cerebral ischemia. In addition, hypobaric hypoxia may impair postural control, psycho-motor, and cognitive performance in patients with COPD during altitude sojourns. Randomized, placebo-controlled trials have shown that preventive treatment with oxygen at night or with acetazolamide reduces the risk of ARAHE in patients with COPD while preventive dexamethasone treatment improves oxygenation and altitude-induced excessive sleep apnea, and lowers systemic and pulmonary artery pressure. This clinical review provides suggestions for pretravel assessment and preparations and measures during travel that may reduce the risk of ARAHE and contribute to pleasant mountain journeys of patients with COPD.

Enhancing potential impact of hospital discharge interventions for patients with COPD: a qualitative systematic review

BackgroundPatients with chronic obstructive pulmonary disease (COPD) are frequently readmitted to hospital resulting in avoidable healthcare costs. Many different interventions designed to reduce hospital readmissions are reported with limited evidence for effectiveness. Greater insight into how interventions could be better designed to improve patient outcomes has been recommended.AimTo identify areas for optimisation within previously reported interventions provided to reduce COPD rehospitalisation to improve future intervention development.MethodsA systematic review was conducted by searching Medline, Embase, CINAHL, PsycINFO, and CENTRAL in June 2022. Inclusion criteria were interventions provided to patients with COPD in the transition from hospital to home or community. Exclusion criteria were lack of empirical qualitative results, reviews, drug trials, and protocols. Study quality was assessed using the Critical Appraisal Skills Programme tool and results were synthesised thematically.ResultsA total of 2,962 studies were screened and nine studies included. Patients with COPD experience difficulties when transitioning from hospital to home. It is therefore important for interventions to facilitate a smooth transition process and give appropriate follow-up post-discharge. Additionally, interventions should be tailored for each patient, especially regarding information provided.ConclusionVery few studies specifically consider processes underpinning COPD discharge intervention implementation. There is a need to recognise that the transition itself creates problems, which require addressing, before introducing any new intervention. Patients report a preference for interventions to be individually adapted—in particular the provision of patient information. Whilst many intervention aspects were well received, feasibility testing may have enhanced acceptability. Patient and public involvement may address many of these concerns and greater use of process evaluations should enable researchers to learn from each other’s experiences.Trial registrationThe review was registered in PROSPERO with registration number CRD42022339523.

Assessment of Serum Electrolytes, Biochemical, and Inflammatory Markers in Predicting COVID-19 Severity in COPD Patients

Background: Chronic obstructive pulmonary disease (COPD) is the most prevalent long-term respiratory condition. Patients with COPD experience detrimental effects of COVID-19 infection. Objective: To figure out whether COPD is a risk factor influencing the progression of COVID-19 and to explore the clinical value of laboratory biomarkers to assess the severity of COVID-19 in patients with COPD comorbidity. Methods: In total, 1572 participants aged 35 to 70 years were enrolled to a tertiary hospital in Bangladesh between March 2022 and October 2022. Participants were categorized into four groups: (1) control, (2) COPD, (3) COVID-19, and (4) COVID-19 with COPD, and blood levels of clinical laboratory markers were assessed to analyze how these markers differ among the study groups. Results: COVID-19 patients with COPD had a significantly lower level of sodium (131.81 ± 2.8 mmol/L) and calcium (1.91 ± 0.28 mmol/L), and a significantly higher level of NT-proBNP (568.45 ± 207.40 pg/mL), bilirubin (1.34 ± 0.54 mg/dL), fibrinogen (577.27 ± 145.24 mg/dL), D-dimer (2.97 ± 2.25 μg/mL), C-reactive protein (71.08 ± 62.42 mg/L), interleukin-6 (166.47 ± 174.39 pg/mL), and procalcitonin (0.25 ± 0.30 ng/mL) compared to other study groups patients (p < 0.0001). In addition, the GOLD 4 group demonstrated significantly altered clinical parameters among COVID-19 patients with COPD. Furthermore, NT-proBNP, interleukin 6, D-dimer, C-reactive protein, and fibrinogen demonstrated excellent diagnostic performance in predicting disease severity among the COVID-19 patients with COPD, with a cut-off value of 511.2 pg/mL, 51.375 pg/mL, 1.645 μg/mL, 40.2 mg/L, and 510 mg/dL, respectively. Our results also indicate that inflammatory markers had significant positive correlations with the biochemical and coagulation markers in the COVID-19 patients suffering with COPD (p < 0.0001). Conclusions: NT-proBNP, interleukin 6, D-dimer, C-reactive protein, and fibrinogen are the most potential parameters for differentiating severe cases of COVID-19.

Vivências de idosos com doença pulmonar crônica em uso de oxigenoterapia domiciliar prolongada no relacionamento amoroso e sexual

Abstract Objective To understand the meanings attributed by older adult with Chronic Obstructive Pulmonary Disease (COPD) using the Long-Term Home Oxygen Therapy (LTOT) regarding romantic relationships and sexual practice. Method Qualitative study in which seven semi-structured interviews were carried out with patients with a confirmed diagnosis of COPD and using LTOT, treated in an outpatient service. The content analysis technique was applied with the support of the WebQDA2.0 software license. COREQ criteria were used to report method and outcome. Results Two categories emerged: 1- Destabilization in the romantic relationship and in the sexual life of the LTOT user: : revealed that therapy causes relationship breakup, change of partner after prescription of the LTOT or even the idea of looking for an extramarital person; 2- Experience and meanings of COPD and oxygen therapy during sexual intercourse: suffering with physiological problems, how much the patient feels short of breath to have sexual intercourse and the impact of this on performance and frequency, reducing these moments with the partner. Conclusion The perception of elderly people with COPD using LTOT indicates that oxygen therapy had an impact on sexual practice and romantic relationships. Having good quality in relationships and sexual practice is a fundamental condition for health promotion.

Predictors of poor clinical outcomes including in-hospital death and low ability to perform activities of daily living at discharge in hospitalized patients with chronic obstructive pulmonary disease exacerbation.

Chronic obstructive pulmonary disease (COPD) is a major cause of mortality and morbidity worldwide. Many patients with COPD experience exacerbations that require hospitalization, which is associated with an increased risk of in-hospital death and impaired ability to perform activities of daily living (ADL). Declining ability to perform ADL is a critical issue for these patients. To identify predictors of poor clinical outcomes, including in-hospital death and low ability to perform ADL at discharge, in patients who are hospitalized with exacerbation of COPD. This retrospective study involved a cohort of patients with exacerbation of COPD who were admitted to Iwata City Hospital in Japan between July 2015 and October 2019. We collected clinical data, measured the cross-sectional area of the erector spinae muscles (ESMCSA) on computed tomography (CT) scans at admission, and investigated the associations of poor clinical outcomes (in-hospital death and severe dependence when performing ADL, defined as a Barthel Index (BI) of ⩽40 at discharge) with clinical parameters. Overall, 207 patients were hospitalized for exacerbation of COPD during the study period. The incidence of poor clinical outcomes was 21.3%, and the in-hospital mortality rate was 6.3%. Multivariate logistic regression analyses showed that older age, long-term oxygen therapy, an elevated D-dimer concentration, and a reduced ESMCSA on chest CT at admission were significantly associated with poor clinical outcomes (in-hospital death and a BI of ⩽40). Hospitalization for exacerbation of COPD was associated with high rates of in-hospital mortality and a BI of ⩽40 at discharge, which may be predicted by assessment of ESMCSA.

Could Melatonin Be an Alternative to Benzodiazepine for Chronic Obstructive Pulmonary Disease With Insomnia?

Chronic obstructive pulmonary disease (COPD) is common, with a 10% global prevalence and a significant health problem, and is one of the main causes of morbidity. Patients with COPD experience various types of sleep problems with insomnia as the most common sleep disorder. The presence of sleep disorders further deteriorates their quality of life. Benzodiazepines (BZDs) are commonly prescribed drugs for insomnia. Several meta-analyses have shown that BZDs effectively reduce insomnia; however, severe side effects including rebound insomnia, next-day hangover, anterograde amnesia, and cognitive impairment occur. Since COPD patients often complain of symptoms such as shortness of breath, safe treatment for sleep disorders is needed. Melatonin supplements have a safe profile and are well-tolerated. Therefore, melatonin can be safely prescribed to treat insomnia in patients with COPD. In addition, due to the anti-inflammatory activity of melatonin, it can be an alternative to BZDs for improving insomnia symptoms without exacerbating respiratory symptoms. It would be helpful to more actively screen and detect sleep disorders in adults with COPD, and to provide safe melatonin treatment for improving their quality of life.

Endurance Time During Constant Work Rate Cycle Ergometry in COPD: Development of an Integrated Database From Interventional Studies.

The COPD Biomarkers Qualification Consortium (CBQC) was formed under COPD Foundation management, with the goal of qualifying biomarkers and clinical outcome assessments through established regulatory processes for chronic obstructive pulmonary disease (COPD). Within CBQC, a working group evaluated opportunities for qualification of an exercise endurance measure. In a recent publication (Chronic Obstr Pulm Dis. 2022; 9[2]:252-265), we described a conceptual framework establishing exercise endurance's direct relationship to an individual with COPD's experience of physical functioning in daily life, and that increase in exercise endurance is a patient-centered, meaningful treatment benefit. We further proposed endurance time during constant work rate cycle ergometery (CWRCE) as a useful efficacy endpoint in clinical therapeutic intervention trials. In this current publication, we describe the process of assembling an integrated database of endurance time responses to interventions in COPD. We sought participant-level data from published studies incorporating CWRCE as an outcome measure. A literature search screened 2993 publications and identified 553 studies for assessment. Two interventions had sufficient data across studies to warrant data extraction: bronchodilators and rehabilitative exercise training. Investigators were contacted and requested to provide participant-by-participant data from their published studies. The final dataset included data from 8 bronchodilator studies (2166) participants and 15 exercise training studies (3488 participants). The database includes 71 variables per participant, comprising demographic, pulmonary function, and detailed physiologic response data. This paper provides a detailed description of the analysis population, while analysis supporting the validation/qualification process and addressing other scientific questions will be described in subsequent publications.

To Assess the Effectiveness of Selected Breathing Exercises among Chronic Obstructive Pulmonary Disease Patients

Mortality rate of chronic obstructive pulmonary disease (COPD) is more than 3 million people every year, making it 3rd largest cause of death in the world. It has been estimated that by the year 2030. chronic obstructive pulmonary disease will become the third biggest cause of death. chronic obstructive pulmonary disease (COPD) is a progressive irreversible airway disease characterized by emphysema and chronic bronchitis, resulting in breathlessness, cough and sputum as the disease progresses, subjects with COPD experience increasing deterioration of their health-related quality of life (HRQOL), with greater impairment in their ability to work and declining participation in social and physical activities. Hence practicing pursed lip breathing exercise in their daily routine will improve their breathing pattern and quality of life.
 Objectives:
 
 To assess the breathing pattern of chronic obstructive pulmonary disease patient.
 To assess the effectiveness of selected breathing exercises among the chronic obstructive pulmonary disease patients.
 To associate the effectiveness of selected breathing exercises among chronic obstructive pulmonary disease patient with their demographic variables.
 
 Materials and Methods: The research approach used for the study was interventional evaluatory approach. The study was conducted in respiratory unit at Wardha City Maharashtra, India, using one group pre test post test design without control group. Non probability purposive sampling technique was used for selecting 60 COPD patients. On the first day pre test assessment of breathing pattern with the help of borg rating scale and provided pursed lip breathing exercise for 20 minutes, 2 times in a day and it was continued for 15 days followed by post test on the 15th day. The data collected, tabulated and analysed in terms of objectives of study using descriptive and inferential statistics.
 Results: The mean post test score. The overall comparison of selected breathing exercise among COPD patients at rest pre test score was higher 3.48 with SD of ±1.25 when compare with at rest post test score which was 0.91 with SD of ±0.85.The statistical Student’s paired t test implies that the difference in the selected breathing exercise among COPD patients was found to be 18.98 which is statistically significant at 0.05% level of significance. Also the overall comparison of selected breathing exercise among COPD patients during activity pre test score was higher 7.95 with SD of ±1.50 when compared with during activity post test score which was 2.76 with SD of ±1.02. The statistical Student’s paired t test implies that the difference in the selected breathing exercise among COPD patients was found to be 18.98 which is statistically significant at 0.05% level of significance. Hence it is statistically interpreted that effectiveness of selected breathing exercises among COPD patients at rest and during activity in post test was effective. The tabulated values was much higher than the calculated’ values at 5% level of significance, also the calculated ‘p-value which was much higher than the acceptable level of significance i.e. ‘p’=0.05. Hence the association of effectiveness of selected breathing exercises is statistically not associated with demographic variables.
 Conclusion: According to the results of this study, patients with Chronic Obstructive Pulmonary disease patients who practiced pursed lip breathing exercise 20 minutes, 2 times a day for 15 days had improvement of the breathing pattern which was statistically proved. Hence pursed lip breathing exercise was cost effective, non invasive, and highly feasible. Hence the researcher concluded that pursed lip breathing exercise can be practice as an effective intervention on improving breathing pattern among chronic obstructive pulmonary disease patients.

A Neural Network Approach for Understanding Patient Experiences of Chronic Obstructive Pulmonary Disease (COPD): Retrospective, Cross-sectional Study of Social Media Content.

BackgroundThe abundance of online content contributed by patients is a rich source of insight about the lived experience of disease. Patients share disease experiences with other members of the patient and caregiver community and do so using their own lexicon of words and phrases. This lexicon and the topics that are communicated using words and phrases belonging to the lexicon help us better understand disease burden. Insights from social media may ultimately guide clinical development in ways that ensure that future treatments are fit for purpose from the patient’s perspective.ObjectiveWe sought insights into the patient experience of chronic obstructive pulmonary disease (COPD) by analyzing a substantial corpus of social media content. The corpus was sufficiently large to make manual review and manual coding all but impossible to perform in a consistent and systematic fashion. Advanced analytics were applied to the corpus content in the search for associations between symptoms and impacts across the entire text corpus.MethodsWe conducted a retrospective, cross-sectional study of 5663 posts sourced from open blogs and online forum posts published by COPD patients between February 2016 and August 2019. We applied a novel neural network approach to identify a lexicon of community words and phrases used by patients to describe their symptoms. We used this lexicon to explore the relationship between COPD symptoms and disease-related impacts.ResultsWe identified a diverse lexicon of community words and phrases for COPD symptoms, including gasping, wheezy, mucus-y, and muck. These symptoms were mentioned in association with specific words and phrases for disease impact such as frightening, breathing discomfort, and difficulty exercising. Furthermore, we found an association between mucus hypersecretion and moderate disease severity, which distinguished mucus from the other main COPD symptoms, namely breathlessness and cough.ConclusionsWe demonstrated the potential of neural networks and advanced analytics to gain patient-focused insights about how each distinct COPD symptom contributes to the burden of chronic and acute respiratory illness. Using a neural network approach, we identified words and phrases for COPD symptoms that were specific to the patient community. Identifying patterns in the association between symptoms and impacts deepened our understanding of the patient experience of COPD. This approach can be readily applied to other disease areas.

Triple therapy in a single inhaler for chronic obstructive pulmonary disease: clinical studies and case report (real practice)

Algorithms for de-escalation of basic therapy, including the abolition of inhaled corticosteroids (ICS), in patients with chronic obstructive pulmonary disease (COPD), as well as the development of clear criteria for prescribing triple therapy in clinical practice remain the subject of numerous studies and discussions. The given case report of managing a patient with a long experience of smoking and severe COPD demonstrated an unsuccessful experience of de-escalation of therapy with the abolition of ICS due to concerns about the fact of pneumonia. The dual bronchodilator therapy prescribed in accordance with modern recommendations was insufficiently effective in preventing exacerbations, and the stabilization of the patient’s condition was observed after the appointment of a fixed triple combination of drugs in a single inhaler (VI/UMEC/FF), which contains vilanterol (VI), umeclidinium bromide (UMEC) and ICS fluticasone furoate (FF). An additional contribution to ensuring clinical success was made by such factors as strict compliance with medical prescriptions by the patient, smoking cessation and compliance with recommendations for maintaining physical activity, compliance with a strict self-isolation regime during the pandemic, which reduced the risks of respiratory viral infections. Additional clinical predictors of the effectiveness of ICS in COPD were the bronchitis type, the persistence of symptoms and the recurrence of exacerbations of the disease after discontinuation of the drug, the level of blood eosinophilia. When deciding whether to prescribe or cancel triple therapy, it is recommended to take into account the data on the effect of ICS on improving the functional parameters and clinical course of the disease with a decrease in symptoms, on reducing the risk of exacerbations, on increasing patient survival and a positive prognosis during COPD.

Macro and meso level influences on distributed integrated COPD care delivery: a social network perspective

BackgroundCare guidelines for people with chronic obstructive pulmonary disease (COPD) recommend an integrated approach for holistic, flexible, and tailored interventions. Continuity of care is also emphasised. However, many patients with COPD experience fragmented care. Discontinuities in healthcare and related social services are likely to result in disjointed rather than integrated care which can negatively affect patient health outcomes. The purpose of this qualitative study was to improve our understanding of, and how, contextual features pertaining to structures and processes of COPD integrated care influence delivery of care within patients’ healthcare networks.MethodsWe conducted individual interviews with 28 participants (9 patients, 16 healthcare professionals, and 3 spousal caregivers). Participants were recruited through the lung clinic at a city hospital in western Canada. We employed a social network paradigm to analyse and interpret the data.ResultsThe analysis revealed an overarching theme of fragmented COPD care with two sub-themes: (1) Funding shortfalls and availability of resources, and (2) Dis(mis)connected communication pathways. The overarching theme depicts variations, delays, and discontinuities in patient care. The sub-themes describe how macro level influences and meso level shortfalls were perceived to influence the availability of respiratory care resources that contributed to fragmented COPD care.ConclusionsEmploying a social network lens drew particular attention to family physicians’ pivotal role in delivering community-based COPD care. While an integrated approach to care is recommended by care guidelines, institutional and organizational structures and processes, such as financial and communication structures, may inhibit delivery of integrated care. Thus, macro and meso level structures and processes have the potential to shape patient care by constraining family physicians’ purposive and communication actions necessary for facilitating an integrated distributed approach to care. We propose a context of care which fosters a context for family physicians’ delivery of patient-centered care. Integrated care delivery may improve patients’ wellbeing and alleviate financial constraints on the healthcare system.

Features of the Metabolic Profile of Saliva in Lung Cancer and COPD: The Effect of Smoking Status.

The aim of the study was to compare the metabolic characteristics of the salivary composition in lung cancer, chronic obstructive pulmonary disease (COPD) and their combination, depending on the smoking history. The study group included 392 patients with lung cancer of various histological types. The division into subgroups was carried out in accordance with the severity of COPD and smoking experience. Salivary biochemical composition was determined according to 34 indicators. For data processing, the principal component method was used. Different groups of biochemical saliva markers are informative when separately accounting for the smoking factor and the presence of COPD in lung cancer. For smoking, antioxidant enzymes and electrolyte components of saliva are informative; for COPD metabolic enzymes, lipid peroxidation products, sialic acids and electrolyte components are informative. While taking into account the smoking factor and the presence of COPD, biochemical markers corresponding to the presence/absence and severity of COPD are the priority. Changes occurring in the background of smoking are of a secondary nature, manifesting as much as possible with a smoking history of more than 50 pack-years. Thus, the metabolic changes that occur in lung cancer in combination with COPD, depending on the smoking factor, can be estimated using saliva.

Disparities in Patient-Centered Communication via Telemedicine.

Purpose: This study investigated disparities in the uptake of telemedicine and the degree of patient-centeredness of telemedicine consultations among vulnerable patient populations. The focus includes rural adults and adults living with psychological distress and a high risk for chronic obstructive pulmonary disease (COPD). Materials and Methods: In August 2020, a random sample of 932 U.S. adults ≥35 years old with a history of smoking tobacco completed an online survey. Chi-squared analyses were conducted to compare the sociodemographics of participants who did and did not use telemedicine. A series of analysis of variance tests were conducted to examine whether satisfaction with patient-centeredness of telemedicine consultations (i.e., open-endedness, expressed empathy, provider's ability, 5-point Likert scale) differs by rural/urban residence, psychological distress, and COPD risk. Results: About 25% of the sample (n = 240) reported having used telemedicine. Telemedicine use was associated with younger age, Hispanic ethnicity, and moderate-to-high psychological distress, but not rurality. Participants reported high general satisfaction with the patient-centeredness of telemedicine consultations (M = 4.42 ± 0.73). However, high psychological distress and identifying as a current smoker were associated with less satisfaction across all domains. High COPD risk was uniquely associated with less satisfaction in how providers express empathy remotely. Conclusion: Individuals with moderate-to-high psychological distress and a high risk for COPD experience challenges accessing high-quality, patient-centered care via telemedicine. As telemedicine becomes ubiquitous in health care, innovative solutions are needed to overcome barriers that prevent providers from delivering patient-centered care and patients from feeling satisfied with their remote consultations.

Comorbid Anxiety and Depression, Though Underdiagnosed, Are Not Associated with High Rates of Low-Value Care in Patients with Chronic Obstructive Pulmonary Disease.

Rationale: Patients with chronic obstructive pulmonary disease (COPD) and anxiety or depression experience more symptoms and exacerbations than patients without these comorbidities. Failure to provide beneficial COPD therapies to appropriate patients (underuse) and provision of potentially harmful therapies to patients without an appropriate indication (overuse) could contribute to respiratory symptoms and exacerbations. Anxiety and depression are known to affect the provision of health services for other comorbid conditions; therefore, underuse or overuse of therapies may explain the increased risk of severe symptoms among these patients.Objectives: To determine whether diagnosed anxiety and depression, as well as significant anxiety and depression symptoms, are associated with underuse and overuse of appropriate COPD therapies.Methods: We analyzed data from a multicenter prospective cohort study of 2,376 participants (smokers and control subjects) enrolled between 2010 and 2015. We identified two subgroups of participants, one at risk for inhaled corticosteroid (ICS) overuse and one at risk for long-acting bronchodilator (LABD) underuse based on the 2011 Global Initiative for Chronic Obstructive Lung Disease statement. Our primary outcomes were self-reported overuse and underuse. Our primary exposures of interest were self-reported anxiety and depression and significant anxiety and depression symptoms. We adopted a propensity-score method with inverse probability of treatment weighting adjusting for differences in prevalence of confounders and performed inverse probability of treatment weighting logistic regression to evaluate all associations between the exposures and outcomes.Results: Among the 1,783 study participants with COPD confirmed by spirometry, 667 (37.4%) did not have an indication for ICS use, whereas 985 (55.2%) had an indication for LABD use. Twenty-five percent (n = 167) of patients reported ICS use, and 72% (n = 709) denied LABD use in each subgroup, respectively. Neither self-reported anxiety and depression nor significant anxiety and depression symptoms were associated with overuse or underuse. At least 50% of patients in both subgroups with significant symptoms of anxiety or depression did not report a preexisting mental health diagnosis.Conclusions: Underuse of LABDs and overuse of ICSs are common but are not associated with comorbid anxiety or depression diagnosis or symptoms. Approximately one-third of individuals with COPD experience anxiety or depression, and most are undiagnosed. There are significant opportunities to improve disease-specific and patient-centered treatment for individuals with COPD.

Experiences of Pulmonary Rehabilitation in People Living with Chronic Obstructive Pulmonary Disease and Frailty. A Qualitative Interview Study.

Rationale: People living with both chronic obstructive pulmonary disease (COPD) and frailty have high potential to benefit from pulmonary rehabilitation but face challenges completing programs. However, research to understand ways to optimize participation in this group is lacking.Objectives: To explore the experiences, needs, and preferences of people with COPD and frailty referred for outpatient pulmonary rehabilitation.Methods: Semistructured interviews with people with COPD and physical frailty, purposively sampled by age, living status, level of frailty, and completion of pulmonary rehabilitation. Thematic analysis with a critical realist perspective was used, involving relevant stakeholders with clinical, academic, and lived experience for interpretive rigor.Results: Nineteen people with COPD and frailty were interviewed, with a median age of 78 years (range, 58–88). Nine did not complete their pulmonary rehabilitation program. Four themes were identified: striving to adapt to multidimensional loss, tensions of balancing support with independence, pulmonary rehabilitation as a challenge worth facing, and overcoming unpredictable disruptions to participation. Participants described constantly adapting to their changing health and resulting multidimensional losses (e.g., functional abilities, relationships, confidence). This involved traversing between independence and seeking support, set against a mismatch between their needs and what support is available. People with COPD and frailty can be highly motivated to participate in pulmonary rehabilitation, despite the physical and mental demands it entails, and report a range of benefits. Yet in the context of changeable health, they must often overcome multiple unpredictable disruptions to completing rehabilitation programs. Participant determination and flexibility of services can facilitate ongoing attendance, but for some, these unpredictable disruptions erode their motivation to attend.Conclusions: People with COPD and frailty experience accumulating, multidimensional loss. This group are motivated to complete pulmonary rehabilitation but often require additional support and flexibility owing to fluctuating and unpredictable health. Person-centered approaches should be considered to minimize disruptive health events and support pulmonary rehabilitation participation and completion. Service adaptations could allow more flexibility to meet the changing needs of this group and enable communication around how pulmonary rehabilitation might align with their priorities.

Improved quality of care by using the PRISMS form to support self‐management in patients with COPD: A Randomised Controlled Trial

To investigate the effects on the quality of care of the Patient Report Informing Self-Management Support (PRISMS) form compared with usual care among patients with chronic obstructive pulmonary disease (COPD) consulting a COPD nurse in primary health care. Patients with COPD experience symptoms affecting their everyday lives, and there is a need for interventions in self-management support. The delivery of chronic care in an organised, structured and planned manner can lead to more productive relationships between professionals and patients. A multicentre randomised controlled trial with a post-test design, according to the CONSORT checklist, in one intervention group (n=94) and one control group (n=108). In addition to usual care, the intervention group (n=94) completed the PRISMS form to indicate areas where they wanted self-management support before the consultation with the COPD nurse. This form comprises 17 items that patients with COPD commonly experience as problems. The control group received usual care (n=108). The primary outcome was patients' satisfaction with quality of care, assessed using the Quality from the Patient's Perspective (QPP) questionnaire. Means and (SD) are presented where applicable. Differences between the intervention and control group were analysed with Student's t test for independent groups for interval data, and the Mann-Whitney U test for ordinal data. Participants in the intervention group were more satisfied with the QPP domains "personal attention," regarding both "perceived reality" (p=.021) and "subjective importance" (p=.012). The PRISMS form revealed "shortness of breath" as the most commonly experienced problem and the issue most desired to discuss. The PRISMS form improved patient satisfaction with quality of care regarding personal attention, which is an important factor in patient participation and improving relationships and communication. The PRISMS form can be a useful tool in improving person-centred care when delivering self-management support. 192691 at http://www.researchweb.org/is/en/sverige/project/192691.

Qualitative Analysis of the Disease Experience of Korean Older Men With Chronic Obstructive Pulmonary Disease.

The current qualitative study explored perceptions and experiences of chronic obstructive pulmonary disease (COPD) among Korean male older adults. Six older adults participated in a narrative group interview. Responses were analyzed to describe perceptions and experiences of COPD. Social stigma, blaming others and the environment, stress to bear alone, and adaptation and management emerged as relevant themes for adaptation to COPD. In relation to obstacles to healthy behaviors after adapting to COPD, emergent themes were adapting to symptoms, external environmental factors, alternative treatments, and insufficient resources. Facilitators of healthy behaviors were past symptom experience, personal volition, and advice from health professionals. Older adult men with COPD trying to adapt to the disease need sufficient resources and social support from families, social networks, and health professionals. Development of interventions for older adults with COPD should include knowledge and understanding of experience and needs. [Journal of Gerontological Nursing, 46(2), 49-56.].

An overview of exacerbations of chronic obstructive pulmonary disease: Can tests of small airways' function guide diagnosis and management?

Chronic obstructive pulmonary disease (COPD) is common and debilitating. Most patients with COPD experience intermittent, acute deterioration in symptoms which require additional therapy, termed exacerbations. Exacerbations are prevalent in COPD and are associated with poor clinical outcomes including death, a faster decline in lung health, and a reduced quality of life. Current guidelines highlight the need to treat exacerbations promptly and then mitigate future risk. However, exacerbations are self-reported, difficult to diagnose and are treated with pharmacological therapies which have largely been unchanged over 30 years. Recent research has highlighted how exacerbations vary in their underlying cause, with specific bacteria, viruses, and cell types implicated. This variation offers the opportunity for new targeted therapies, but to develop these new therapies requires sensitive tools to reliably identify the cause, the start, and end of an exacerbation and assess the response to treatment. Currently, COPD is diagnosed and monitored using spirometric measures, principally the forced expiratory volume in 1 s and forced vital capacity, but these tests alone cannot reliably diagnose an exacerbation. Measures of small airways' function appear to be an early marker of COPD, and some studies have suggested that these tests might also provide physiological biomarkers for exacerbations. In this review, we will discuss how exacerbations of COPD are currently defined, stratified, monitored, and treated and review the current literature to determine if tests of small airways' function might improve diagnostic accuracy or the assessment of response to treatment.
