A systematic literature review (SLR; 2021-2023), complemented with a targeted literature review (TLR; 2013-2023) identified 2039 publications on the economic and humanistic burden of severe COPD. Additionally, an SLR and complementary TLR to evaluate the impact of environmental and sociodemographic factors on COPD (2013-2023), identified 1018 records. All searches were conducted on November 17, 2023. After applying prespecified selection criteria, 50 studies reporting on the humanistic and economic impact of COPD, and six studies on the environmental and sociodemographic impact, were selected. Severe COPD significantly impairs health-related quality of life, exerting effects on physical and psychological well-being, with a progressive decline as COPD worsens from mild to very severe. Evidence indicates that there is a significant burden of disease due to exacerbations of COPD, with their frequency and severity increasing with disease progression, and an increased mortality risk associated with very severe versus severe COPD. The studies reported a high frequency of healthcare resource utilization, including primary care visits, emergency department visits, and hospitalizations among patients with severe COPD, all of which contribute to a significant economic burden, particularly in patients with advanced disease. Environmental factors demonstrated diverse impacts on outcomes for individuals with severe COPD, varying by type of pollutant, disease severity, and patient characteristics. Studies examining the sociodemographic impact of underserved populations on the burden of severe COPD were not identified. Severe COPD is a multifaceted disease that imposes considerable humanistic and economic impact on both patients and healthcare systems.

The aim of the present study was to combine data from two randomized controlled trials conducted in Denmark in similar healthcare settings to explore number of hospitalizations for COPD, days of admission, and exacerbations treated outside hospitals.</p><p><strong>Methods: </strong>Recruitment took place during hospitalization for AECOPD and from outpatient COPD clinics. Patients were equally randomized to telemonitoring (N=251) in addition to usual care for six months or usual care alone (N=252). We used a negative binomial regression model with between-group comparisons expressed as incidence rate ratios (IRRs) for assessment of hospitalizations, admission days and moderate exacerbations and Kaplan-Meier time-to-event analysis for assessment of time to first COPD hospitalization.</p><p><strong>Results: </strong>No significant differences between the two studies were identified. In combined analyses, numerically fewer hospitalizations (IRR 0.85, 95% CI 0.62-1.17) and hospitalization days (IRR 0.72, 95% CI 0.42-1.23) were seen in the telemonitoring group, but the findings did not reach statistical significance whereas treatment for moderate exacerbations was significantly more frequent in the telemonitoring group (IRR 1.91, 95% CI 1.49-2.45).</p><p><strong>Conclusion: </strong>No effect of telemonitoring on hospitalizations for AECOPD was documented in this large cohort of patients with severe COPD. However, the telemonitoring group received significantly more treatment for moderate exacerbations. This risk of overtreatment should be considered when telemonitoring is used in the care of patients with COPD.</p>","PeriodicalId":48818,"journal":{"name":"International Journal of Chronic Obstructive Pulmonary Disease","volume":"20 ","pages":"2361-2369"},"PeriodicalIF":2.7,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12262086/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144643929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Appropriate treatment is possible if patients at a high risk of treatment failure at the start of treatment are properly identified. Therefore, this study examined the factors associated with initial treatment failure in patients with ECOPD.</p><p><strong>Patients and methods: </strong>We conducted a cohort study involving patients with ECOPD admitted to our hospital. The primary outcome was initial treatment failure, defined as a composite of treatment intensification for ECOPD and in-hospital mortality. Uni- and multivariate analyses were performed to identify the factors associated with initial treatment failure.</p><p><strong>Results: </strong>The analysis included data of 152 patients with a mean age of 76±8 years (mean±standard deviation); 81% of them were male patients. Treatment failure occurred in 26 (17%) patients. These included nine, two, one, and 14 patients who changed antimicrobial agents, received additional non-invasive positive pressure ventilation therapy due to non-improvement or symptom exacerbation, received additional invasive positive pressure ventilation therapy, and died in the hospital, respectively. Using multivariable analysis, home oxygen therapy (odds ratio, 5.335; 95% confidence interval, [1.542-18.457]), neutrophil count ≥7000 cells/µL (3.550; [1.007-12.519]), and acidemia (3.129; [1.009-9.698]) were significant factors associated with treatment failure. In patients treated with narrow-spectrum antibiotics as the initial antibacterial therapy, the treatment failure rate in patients receiving home oxygen therapy was significantly higher than in those receiving none.</p><p><strong>Conclusion: </strong>Home oxygen therapy, high neutrophil count, and acidemia on admission were risk factors for treatment failure.
