Self-management interventions for chronic obstructive pulmonary disease (COPD) can improve quality of life, reduce hospital admissions, and improve symptoms. However, many factors impede engagement for patients and practitioners. Qualitative research, with its focus on subjective experience, can provide invaluable insights into such factors. Therefore, a systematic review and synthesis of qualitative evidence on COPD self-management from the perspective of patients, carers, and practitioners was conducted. Following a systematic search and screening, 31 studies were appraised and data extracted for analysis...

BACKGROUND: Inhaled drug delivery is the cornerstone treatment for asthma and chronic obstructive pulmonary disease (COPD). However, use of inhaler devices can be challenging, potentially leading to critical errors in handling that can significantly reduce drug delivery to the lungs and effectiveness of treatment. METHODS: A systematic review was conducted to define 'critical' errors and their impact on health outcomes and resource use between 2004 and 2016, using key search terms for inhaler errors in asthma and COPD (Search-1) and associated health-economic and patient burden (Search-2)...

BACKGROUND: Cigarette smoking is the strongest risk factor for COPD. Smoking burden is frequently measured in pack-years, but the relative contribution of cigarettes smoked per day versus duration towards the development of structural lung disease, airflow obstruction and functional outcomes is not known. METHODS: We analysed cross-sectional data from a large multicentre cohort (COPDGene) of current and former smokers. Primary outcome was airflow obstruction (FEV1/FVC); secondary outcomes included five additional measures of disease: FEV1, CT emphysema, CT gas trapping, functional capacity (6 min walk distance, 6MWD) and respiratory morbidity (St George's Respiratory Questionnaire, SGRQ)...

Cigarette smoking is a major cause of chronic obstructive pulmonary disease (COPD). Inhalation of cigarette smoke causes inflammation of the airways, airway wall remodelling, mucus hypersecretion and progressive airflow limitation. Much of the disease burden and health care utilisation in COPD is associated with the management of its comorbidities and infectious (viral and bacterial) exacerbations (AECOPD). Comorbidities, in particular skeletal muscle wasting, cardiovascular disease and lung cancer markedly impact on disease morbidity, progression and mortality...

COPD is a complex, heterogeneous condition. Even in the early clinical stages, COPD carries a significant burden, with breathlessness frequently leading to a reduction in exercise capacity and changes that correlate with long-term patient outcomes and mortality. Implementation of an effective management strategy is required to reduce symptoms, preserve lung function, quality of life, and exercise capacity, and prevent exacerbations. However, current clinical practice frequently differs from published guidelines on the management of COPD...

Chronic obstructive pulmonary disease (COPD) is a leading cause mortality and morbidity globally, with permanently growing prevalence. Expressive underdiagnosis and undertreatment is a general features across all European countries. Individuals with undiagnosed, symptomatic COPD had significantly increased risk of exacerbations, pneumonia, and death. Early smoking cessation is able to reduce the mortality and morbidity burden of newly diagnosed COPD individuals. These findings suggest that better initiatives for early diagnosis and early treatment of COPD are needed...

In most low and middle-income countries, chronic obstructive pulmonary disease (COPD) is on the rise. Areas covered: Unfortunately, COPD is a neglected disease in these countries. Taking sub-Saharan Africa as an example, in rural areas, COPD is even unknown regarding public awareness and public health planning. Programs for the management of COPD are poorly developed, and the quality of care is often of a low standard. Inhaled medication is often not available or not affordable. Tobacco smoking is the most common encountered risk factor for COPD...

Much of the current burden of long-latency respiratory disease (LLRD) in Great Britain is attributed to historical asbestos exposure. However, continuing exposure to other agents, notably silica, also contributes to disease burden. The aim of this study was to investigate the incidence of work-related LLRD reported by chest physicians in Great Britain, including variations by age, gender, occupation and suspected agent.LLRD incidence and incidence rate ratios by occupation were estimated (1996-2014). Mesothelioma cases by occupation were compared with proportional mortality ratios...

Background: The aim of this study was to estimate the occupational burden of airflow limitation, chronic airflow limitation, COPD, and emphysema. Materials and methods: Subjects aged 50-64 years (n=1,050) were investigated with forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC). Airflow limitation was defined as FEV1/FVC <0.7 before bronchodilation. Chronic airflow limitation was defined after bronchodilation either according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) as FEV1/FVC <0...

BACKGROUND: Long-term non-invasive ventilation (NIV) is an established and increasingly used treatment option for patients with chronic hypercapnic chronic obstructive pulmonary disease (COPD). Following inpatient NIV establishment, inpatient control visits regularly occur thereafter. However, it remains unclear whether such control visits can also be performed in an outpatient setting, which, in turn, would reduce costs, patient burden and the complications related to hospitalization...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a significant cause of morbidity and mortality in England, however estimates of its prevalence vary considerably. Routinely collected and coded primary care data can be used to monitor disease prevalence, however reliance upon diagnostic codes alone is likely to miss cases. METHODS: We devised an ontological approach to COPD case detection and implemented it in a large primary care database to identify definite and probable cases of COPD...

New patients in the secondary respiratory care require more time for the first consultation and place a higher diagnostic and therapeutic demand if compared to patients already in chronic care. More diagnostic procedures and patient's education by the team are required. No such burden is observed regarding differential degrees of severity of respiratory diseases, e. g. COPD. The overall demands add up to twice the demands of patients already in care. Thus the time required for the treatment of 50 new patients allows consultations for 100 patients already known in the office...

A vaccine against Moraxella catarrhalis will reduce tremendous morbidity, mortality, and financial burden by preventing otitis media in children and exacerbations of COPD in adults. Oligopeptide permease A (OppA) is a candidate vaccine antigen that is 1) a nutritional virulence factor expressed on the bacterial cell surface during infection, 2) widely conserved among strains, 3) highly immunogenic, and 4) a protective antigen based on its capacity to induce protective responses in immunized animals. In the present study, we show that the antibodies to OppA following vaccination mediate accelerated clearance in animals following pulmonary challenge...

AIMS AND OBJECTIVES: To explore the experience of patients affected by COPD following hospitalization due to an acute exacerbation event. BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a progressively debilitating disease, often with very burdensome symptoms such as acute and chronic breathlessness and fatigue. Acute exacerbation often creates a life threatening event. Exacerbation can also have substantial psychological effects including anxiety and depression although this aspect is less well researched - especially amongst people with COPD recovering from an acute event and facing a return home...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) exacerbations are associated with high disease burden and costs, especially in the case of hospitalizations. The overall number of hospital admissions due to exacerbations of COPD has increased. It is remarkable that re-admissions account for a substantial part of these hospitalizations. This pilot study investigates the use of case management to reduce re-admissions due to COPD. METHODS: COPD patients with more than one hospitalization per year due to an exacerbation were included...

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) can be classified into groups A/C or B/D based on symptom intensity. Different threshold values for symptom questionnaires can result in misclassification and, in turn, different treatment recommendations. The primary aim was to find the best fitting cut-points for Global initiative for chronic Obstructive Lung Disease (GOLD) symptom measures, with an modified Medical Research Council dyspnea grade of 2 or higher as point of reference...

COPD patients are burdened with a daily risk of acute exacerbation and loss of control, which could be mitigated by effective, on-demand decision support tools. In this study, we present a machine learning-based strategy for early detection of exacerbations and subsequent triage. Our application uses physician opinion in a statistically and clinically comprehensive set of patient cases to train a supervised prediction algorithm. The accuracy of the model is assessed against a panel of physicians each triaging identical cases in a representative patient validation set...
