Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a frequently diagnosed yet treatable condition, provided it is identified early and managed effectively. This study aims to develop an advanced COPD diagnostic model by integrating deep learning and radiomics features. METHODS We utilized a dataset comprising CT images from 2,983 participants, of which 2,317 participants also provided epidemiological data through questionnaires. Deep learning features were extracted using a Variational Autoencoder, and radiomics features were obtained using the PyRadiomics package. Multi-Layer Perceptrons were used to construct models based on deep learning and radiomics features independently, as well as a fusion model integrating both. Subsequently, epidemiological questionnaire data were incorporated to establish a more comprehensive model. The diagnostic performance of standalone models, the fusion model and the comprehensive model was evaluated and compared using metrics including accuracy, precision, recall, F1-score, Brier score, receiver operating characteristic curves, and area under the curve (AUC). RESULTS The fusion model exhibited outstanding performance with an AUC of 0.952, surpassing the standalone models based solely on deep learning features (AUC = 0.844) or radiomics features (AUC = 0.944). Notably, the comprehensive model, incorporating deep learning features, radiomics features, and questionnaire variables demonstrated the highest diagnostic performance among all models, yielding an AUC of 0.971. CONCLUSION We developed and implemented a data fusion strategy to construct a state-of-the-art COPD diagnostic model integrating deep learning features, radiomics features, and questionnaire variables. Our data fusion strategy proved effective, and the model can be easily deployed in clinical settings. TRIAL REGISTRATION Not applicable. This study is NOT a clinical trial, it does not report the results of a health care intervention on human participants.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) management in China is far from adequate; underdiagnosis and undertreatment are major barriers to optimal care and improved patient outcomes. OBJECTIVE To generate reliable information on COPD management, outcomes, treatment patterns and adherence, and disease knowledge in China in a real-world setting. DESIGN A 52-week multicentre, prospective, observational study. METHODS Outpatients (⩾40 years old) diagnosed with COPD were enrolled from 50 secondary and tertiary hospitals across six geographical regions. Data were collected in routine clinical practice. RESULTS Between June 2017 and January 2019, 5013 patients were enrolled and 4978 included in the analysis. Mean [standard deviation (SD)] age was 66.2 (8.9) years, 79.5% were male and 90% had moderate-to-very-severe airflow limitation. Annual rates of overall and severe exacerbation were 0.56 and 0.31, respectively. During 1 year, 1536 (30.8%) patients experienced ⩾1 exacerbation and 960 (19.3%) patients had ⩾1 exacerbation requiring hospitalization/emergency visit. Mean (SD) COPD assessment test score was 14.6 (7.6) at baseline and 10.6 (6.8) at follow-up; however, 42-55% of patients had persistent dyspnoea, chest tightness and wheezing at 1 year. The most prescribed treatments were inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) (36.0%), ICS/LABA + long-acting muscarinic antagonist (LAMA) (17.7%) and LAMA monotherapy (15.3%). Among patients with high exacerbation risk (GOLD Groups C and D), 10.1% and 13.1%, respectively, did not receive any long-acting inhalers; only 53.8% and 63.6% of Group C and D patients with ⩾1 exacerbation during follow-up were prescribed ICS-containing therapy, respectively. Mean (SD) adherence for long-acting inhalers was 59.0% (34.3%). Mean (SD) score for the COPD questionnaire was 6.7 (2.4). CONCLUSION These results indicate a high burden of severe exacerbations and symptoms in Chinese outpatients with COPD, and low adherence with treatment guidelines, highlighting the need for more effective management nationwide. REGISTRATION The trial was registered on 20 March 2017 (ClinicalTrials.gov identifier: NCT03131362).

Ther Adv Respir Dis 2023; 17:17534666231167353. [PMID: 37073797 PMCID: PMC10126609 DOI: 10.1177/17534666231167353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Accepted: 03/17/2023] [Indexed: 04/20/2023] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) management in China is inadequate and there is a need to improve care and outcomes for patients nationwide. OBJECTIVES The REAL study was designed to generate reliable information on COPD management from a representative sample of Chinese patients with COPD. Here, we present study outcomes related to acute exacerbations. DESIGN A 52-week, multicentre, prospective, observational study. METHODS Outpatients (aged ⩾ 40 years) enrolled from 25 tertiary and 25 secondary hospitals across six geographic regions in China were followed for 12 months. Risk factors for COPD exacerbation and disease severity by exacerbation were assessed using multivariate Poisson and ordinal logistic regression models, respectively. RESULTS Between June 2017 and January 2019, 5013 patients were enrolled, with 4978 included in the analysis. Mean (standard deviation) age was 66.2 (8.9) years. More patients presented with exacerbations in secondary versus tertiary hospitals (59.4% versus 40.2%) and in rural versus urban areas (53.2% versus 46.3%). Overall exacerbation rates differed across regions (range: 0.27-0.84). Patients from secondary versus tertiary hospitals had higher rates of overall exacerbation (0.66 versus 0.47), severe exacerbation (0.44 versus 0.18) and exacerbation that resulted in hospitalisation (0.41 versus 0.16). Across regions and hospital tiers, the rates of overall exacerbation and exacerbations that resulted in hospitalisation were highest in patients with very severe COPD (based on the severity of airflow limitation or GOLD 2017 combined assessment). Strong predictors of exacerbation included demographic and clinical characteristics, modified Medical Research Council scores, mucus purulence, exacerbation history and the use of maintenance mucolytic treatment. CONCLUSION COPD exacerbation rates varied across regions and were higher in secondary compared with tertiary hospitals in China. Understanding the factors associated with COPD exacerbation may facilitate improved management of COPD exacerbations in China. REGISTRATION The trial was registered on 20 March 2017 (ClinicalTrials.gov: NCT03131362; https://clinicaltrials.gov/ct2/show/NCT03131362). PLAIN LANGUAGE SUMMARY Exacerbations in patients with chronic obstructive pulmonary disease in ChinaBackground: Chronic obstructive pulmonary disease (COPD) causes progressive and irreversible airflow limitation. As the disease progresses, patients often experience a flare up of symptoms referred to as an exacerbation. There is inadequate management of COPD in China and, therefore, there is a need to improve care and outcomes for patients across the country.Objective: This study aimed to generate reliable information on exacerbations among Chinese patients with COPD to help inform future management strategies.Study design and methods: Patients (aged ⩾ 40 years) were enrolled from 25 secondary and 25 tertiary hospitals across six regions of China. Physicians collected data over 1 year during routine outpatient visits.Results: There were more patients who experienced an exacerbation in secondary versus tertiary hospitals (59% versus 40%) and in rural versus urban areas (53% versus 46%). Patients in different geographic regions experienced varying frequencies of exacerbations over 1 year. Compared with patients from tertiary hospitals, patients from secondary hospitals experienced exacerbations (including exacerbations that were severe and those that resulted in hospitalisation) at a higher frequency over 1 year. Patients with very severe disease experienced exacerbations (including exacerbations that resulted in hospitalisation) at the highest frequency over 1 year, regardless of the patient's geographic region or hospital tier. Patients who had certain characteristics and symptoms, had exacerbation(s) over the previous year, or received medication that aids in the clearance of mucus were more likely to experience exacerbations.Conclusion: The frequency of exacerbations among Chinese patients with COPD varied between patients living in different geographic regions and between patients presenting to different hospital tiers. Understanding the factors related to the occurrence of an exacerbation may help physicians better manage the disease.

Abstract
Objective To evaluate the real-world situation for the management of chronic obstructive pulmonary disease (COPD) and poorly controlled disease risk factors in the Chinese community. Methods This retrospective multicentre study analysed data from COPDMICand MICHC in Shanghai Songjiang District, Shanghai, China. The differences in COPD Assessment Test (CAT), the modified Medical Research Council (mMRC) dyspnea scale, and the number of emergency cases, emergency visits, inpatient cases, and hospitalisations from January 2018 to December 2020 were analysed. The impact of coronavirus disease 2019 (COVID-19) on COPD management was also assessed. Results For 2020 versus 2018, analysis of 468 COPD cases from COPDMIC matched with MICHC data showed significantly more patients with improved mMRC grades, significantly fewer emergency cases and emergency visits, and significantly fewer hospitalisation cases and hospitalisations. Differences in the number of emergency visits and hospitalisations per capita were statistically significant. Compared to GOLD 3-4, GOLD 1-2 patients showed significant improvements in CAT score, mMRC grade, the number of emergency visits and hospitalisations per capita. Treatment adherence from 2018 to 2020 was 25%, 29.1%, and 6.8%, and the proportion of medication regimens consistent with guidelines was 43.44%, 50.98%, and 71.87%, respectively. Higher treatment adherence resulted in significantly improved CAT scores and mMRC grades and fewer emergency department visits and hospitalisations per capita. Conclusion Combined with remote management tools, patients with COPD achieved continuous improvement in symptoms and exacerbations over 3 years. In the context of COVID-19 prevention/control measures, improvements were significant for patients with GOLD 1-2 COPD but limited with GOLD 3-4. Pharmacologic treatment significantly improved clinical symptoms and reduced emergency visits and hospitalisations. Severe airflow limitation and poor adherence to pharmacologic treatment were important risk factors for lack of disease remission.

Abstract
OBJECTIVES This study aimed to assess and predict the disease burden attributable to chronic obstructive pulmonary disease (COPD) in a timely, comprehensive, and reliable manner, thereby mitigating the health hazards of COPD. STUDY DESIGN AND METHODS Data on the disease burden owing to COPD from 1990 to 2019 were extracted from the Global Burden of Disease (GBD) Study 2019. Linear regression analysis was used to calculate the estimated annual percentage change (EAPC) in the age-standardized rates. Non-parametric tests were used for subgroup analysis. The Bayesian age-period-cohot (BAPC) model integrated nested Laplace approximations to predict the disease burden over the next 25 years. Sensitivity analysis was performed using the Norpred APC model. RESULTS Globally, the COPD-related age-standardized incidence rate decreased from 216.48/100,000 in 1990 to 200.49/100,000 in 2019, with an EAPC of -0.33. But the number of new cases increased from 8,722,966 in 1990 to 16, 214, 828 in 2019. Trends in prevalence, deaths, and disability-adjusted life years (DALYs) were the same as incidence. There were significant differences in disease burden between the genders and all age groups (P < 0.05) in China. The projections suggested that the COPD-related number of new cases and deaths in China would increase by approximately 1.5 times over the next 25 years. CONCLUSIONS The number of incidence, prevalence, deaths, and DALYs had all increased in China in the past and would continue to grow over the next 25 years. Therefore, measures should be taken to target risk factors and high-risk groups.

Abstract
Background Chronic obstructive pulmonary disease (COPD) receives low awareness and is undertreated in China. Understanding the burden and treatment of COPD across the nation is important for improving quality of care for this disease. This study aims to reveal the current situation of COPD severity distribution and management across China. Methods Baseline data from REALizing and Improving Management of Stable COPD in China, a multicentre, prospective, longitudinal, observational study, were analysed. Patients diagnosed with COPD as per Global Initiative for Chronic Obstructive Lung Disease 2016 (GOLD 2016) criteria were enrolled from 50 randomly selected hospitals (tertiary, 25; secondary, 25) across six geographical regions. Data were collected in routine clinical settings. Results Between 15 December 2017 and 6 August 2020, 5013 patients were enrolled and 4978 included in the full analysis set. Of these, 2459 (49.4%) reported ≥ 1 exacerbation within 12 months prior to study enrolment, with a mean annual rate of 0.9/patient, including 0.2/patient and 0.5/patient leading to emergency room visits and hospitalisation, respectively. Spirometry graded 458 (10.1%), 1886 (41.7%), 1558 (34.5%), and 616 (13.6%) were GOLD stage I–IV, and 536 (11.4%), 1034 (22.0%), 563 (12.0%), and 2566 (54.6%) were classified as GOLD 2016 Group A–D, respectively, without evident regional variations. Inhaled corticosteroids plus long-acting beta2-agonist (ICS/LABA, 1316 [26.4%]), ICS/LABA plus long-acting muscarinic antagonist (ICS/LABA + LAMA, 871 [17.5%]), and LAMA (754 [15.1%]) were prescribed at high rates across all groups and regions. Medications not recommended by GOLD were commonly prescribed (TCM, 578 [11.6%]; others, 951 [19.1%]), and 681 (13.7%) were not given ICS or long-acting bronchodilators. Conclusions Disease burden among Chinese COPD outpatients is high. Improved guideline adherence for COPD treatment is needed. Trial registration ClinicalTrials.gov identifier, NCT03131362.

Triple Versus Dual Combination Therapy in Chronic Obstructive Pulmonary Disease in Asian Countries: Analysis of the IMPACT Trial. Pulm Ther 2021; 7:101-118. [PMID: 33201438 PMCID: PMC8137798 DOI: 10.1007/s41030-020-00136-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Accepted: 10/15/2020] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION In the IMPACT trial, single-inhaler triple therapy fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) reduced moderate/severe exacerbation rates versus FF/VI or UMEC/VI dual therapy in patients with chronic obstructive pulmonary disease (COPD); however, pneumonia incidence was higher in FF-containing arms. As COPD is a growing problem in Asia, we compared the efficacy and safety of FF/UMEC/VI in Asia versus non-Asia regions. METHODS IMPACT was a double-blind, 52-week trial in symptomatic COPD patients with ≥ 1 moderate/severe exacerbation in the prior year. This pre-specified analysis evaluated the annual rate of moderate/severe exacerbations, change from baseline in trough forced expiratory volume in 1 s, and St George's Respiratory Questionnaire total score, mortality, and safety (including pneumonia) in Asia versus non-Asia regions. RESULTS The intent-to-treat population comprised 10,355 patients (Asia n = 1644 [16%]). Rate ratios (95% confidence intervals) for moderate/severe exacerbations with FF/UMEC/VI were 0.89 (0.76-1.05) versus FF/VI and 0.86 (0.71-1.04) versus UMEC/VI in Asia, and 0.84 (0.79-0.90) and 0.74 (0.68-0.80) in non-Asia. Efficacy of FF/UMEC/VI on other endpoints was similar in both regions. There was an increased incidence of investigator-reported pneumonia in patients in Asia (FF/UMEC/VI: 13%; FF/VI: 14%; UMEC/VI: 6%) compared with non-Asia (FF/UMEC/VI: 6%; FF/VI: 5%; UMEC/VI: 4%). The increased risk of pneumonia in patients in Asia was most marked in patients with lower body mass index, lower lung function, and taking inhaled corticosteroids. In post hoc analysis of adjudicated on-treatment all-cause mortality, probabilities of death were numerically lower in both regions with FF/UMEC/VI (Asia: 1.16%; non-Asia: 1.35%) and FF/VI (Asia: 1.77%; non-Asia: 1.21%) versus UMEC/VI (Asia: 1.91%; non-Asia: 2.23%). CONCLUSIONS FF/UMEC/VI provides similar benefits in COPD patients in Asia and non-Asia regions. Clinical benefits of treatment, including reduction in mortality risk, should be weighed against risk of pneumonia, taking account of all known risk factors.
