The use of transesophageal bronchoscopic ultrasound-guided fine needle aspiration (EUS-B-FNA) by pulmonologists has expanded significantly, since it enables effective diagnosis of lesions in the mediastinum and upper abdomen. The following case demonstrates the safety and feasibility of EUS-B-FNA in a patient with non-small cell lung cancer (NSCLC) cancer and a pancreatic mass of unknown origin. A patient who was previously diagnosed with NSCLC was referred to the Department of Respiratory Medicine, Odense University Hospital due to suspected recurrence of NSCLC. The patient underwent endobronchial ultrasound guided (EBUS)-FNA from several suspected mediastinal lymph nodes and combined EUS-B-FNA from a pancreatic mass during the same procedure.

The impact of sociodemographic factors on agreement between the two data sources was also assessed. Cross-sectional data were extracted from a Swedish longitudinal cohort study. In total, 401 non-hospitalized patients with a polymerase chain reaction-confirmed COVID-19 infection responded to a survey and agreed to a review of their electronic medical records. Agreement, estimated using the kappa statistic, sensitivity, and specificity were calculated for nine diagnoses and eleven symptoms. Differences between subgroups based on sociodemographic factors were assessed. The agreement between the self-reported data and medical records was at a substantial to moderate level for diagnoses such as diabetes mellitus (kappa 0.65, sensitivity 86%) and hypertension (kappa 0.59, sensitivity 56%) and at a fair level for more difficult-to-define conditions such as ongoing immunosuppressive treatment (kappa 0.27, sensitivity 25%). The agreement between the two data sources on symptoms was between fair and poor (kappa 0.36 for fever; kappa 0.05 for fatigue). Agreement for some diagnoses and symptoms varied across some sociodemographic subgroups, e.g. agreement in diabetes mellitus was significantly better in males (kappa 1.0) than females (kappa 0.52, homogeneity tests p = 0.02). In general, kappa values were lower for symptoms than diagnoses. The agreement between the two sources varied with diagnoses and symptoms and was also influenced by sociodemographic factors. This study illustrates that it is important to consider type of data used in the epidemiological studies as different information sources differ with quality and accuracy.","PeriodicalId":11872,"journal":{"name":"European Clinical Respiratory Journal","volume":"57 9","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
