Bronchoscopist's perception of the quality of the single-use bronchoscope (Ambu aScope4™) in selected bronchoscopies: a multicenter study in 21 Spanish pulmonology services. Respir Res. 2020 Dec 2;21(1):320.http://hdl.handle.net/10668/3431Background: The disposable bronchoscope is an excellent alternative to face the problem of SARS-CoV-2 and other cross infections, but the bronchoscopist's perception of its quality has not been evaluated. Methods: To evaluate the quality of the Ambu-aScope4 disposable bronchoscope, we carried out a cross-sectional study in 21 Spanish pulmonology services. We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy. The variables were described with absolute and relative frequencies, measures of central tendency and dispersion depending on their nature. The existence of learning curves was evaluated by CUSUM analysis. Results: The most frequent indications in 300 included bronchoscopies was bronchial aspiration in 69.3% and the median duration of these was 9.1 min. The route of entry was nasal in 47.2% and oral in 34.1%. The average score for ease of use, image, and aspiration quality was 80/100. All the planned techniques were performed in 94.9% and the bronchoscopist was satisfied in 96.6% of the bronchoscopies. They highlighted the portability and immediacy of the aScope4TM to start the procedure in 99.3%, the possibility of taking and storing images in 99.3%. The CUSUM analysis showed average scores > 70/100 from the first procedure and from the 9th procedure more than 80% of the scores exceeded the 80/100 score. Conclusions: The aScope4™ scored well for ease of use, imaging, and aspiration. We found a learning curve with excellent scores from the 9th procedure. Bronchoscopists highlighted its portability, immediacy of use and the possibility of taking and storing images.9 p.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/BronchoscopyQualityCUSUM analysisaScope4™Bronchoalveolar lavageMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Surgical Procedures, Operative::Thoracic Surgical Procedures::Pulmonary Surgical Procedures::BronchoscopyMedical Subject Headings::Health Care::Health Services Administration::Quality of Health Care::Clinical CompetenceMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cross-Sectional StudiesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Equipment DesignMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::Health Care SurveysMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Psychiatry and Psychology::Psychological Phenomena and Processes::Psychology, Applied::Psychology, Educational::Learning::Learning CurveMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cohort Studies::Longitudinal Studies::Prospective StudiesMedical Subject Headings::Geographical Locations::Geographic Locations::Europe::SpainMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Attitude::Attitude of Health PersonnelMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Diagnostic Equipment::Endoscopes::BronchoscopesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Disposable EquipmentMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Attitude::Attitude to Health::Health Knowledge, Attitudes, Practiceresearch article33267892open access10.1186/s12931-020-01576-w1465-993X
