Background: Non-invasive ventilation (NIV) has been shown to be the most appropriate therapy for COPD patients with chronic respiratory failure. While physiological parameters and long-term outcome frequently serve as primary outcomes, very few studies have primarily addressed the impact of NIV initiation on sleep quality in COPD. Methods: This single-center prospective cohort study comprised NIV-naïve patients with COPD. All patients underwent polysomnographic evaluation both at baseline and at 3 months follow-up, accompanied by the assessment of health-related quality of life (HRQL) using the Severe Respiratory Insufficiency Questionnaire (SRI) and the Epworth Sleepiness Scale (ESS). A subgroup evaluation was performed to address the impact of comorbid obstructive sleep apnea syndrome (OSAS). Results: Forty-six patients were enrolled and twenty-five patients completed the follow-up period (66.7 ± 7.4 years). NIV resulted in an increase in slow-wave sleep (+2% (−3.5/7.5), p = 0.465) and rapid eye movement sleep (+2.2% (−1.0/5.4), p = 0.174), although no statistical significance could be detected. ESS (−1.7(−3.6/0.1), p = 0.066) also showed a positive trend. Significant improvements in the Respiratory Disturbance Index (RDI) (−12.6(−23.7/−1.5), p = 0.027), lung function parameters, transcutaneous PCO
2 and the SRI summary scale (4.5(0.9/8), p = 0.016) were observed. Conclusion: NIV therapy does not decrease sleep quality and is even capable of improving HRQL, transcutaneous PaCO2 , daytime sleepiness and RDI, and the latter especially holds true for patients with comorbid OSAS.

Background/Objective: To assess whether and how the use of scientifically established Web-based training videos for teaching correct inhalation technique in patients with chronic airway diseases has become accepted among the wider population. Methods: The viewing trends of 141 freely available YouTube videos (full playing time, 01:31–04:37 min:s) provided by the German Respiratory League, covering a broad range of internationally prescribed devices, were analyzed over a 10-year period. Specific emphasis was placed both on German and international videos. Results: The total number of views was 3,350,678. Non-German videos (English, Russian, Turkish, Greek, Arabic, Farsi, and Slovakian) accounted for 23.2% of the views. The number of views steadily increased between 2011 and 2020 with a mean annual increase of 54.0% (range 24.5/119.9%) compared to the respective previous year. By 2020, the incidence of views per 100,000 German inhabitants was 725 for German videos only and 1,030 for all videos. In terms of the annual trend, there were two peak viewing periods, namely in spring and late fall, while the lowest amount of views occurred in summer. Conclusion: This study highlights the rising impact of Web-based training videos used for teaching the correct use of inhalation devices, with a steady increase in the number of annual views and a clear seasonal peaking of views in spring and late fall.

Background: Electronic auscultation technology has advanced dramatically in the last few years. Therefore, long-term pulmonary auscultation could provide additional information about respiratory system by monitoring acute chronic obstructive pulmonary disease (AECOPD) exacerbations or by identifying wheezing phenotypes amongst stable COPD patients. Objectives: Comparison of respiratory sounds in stable versus AECOPD patients recorded with a portable respiratory sound monitor over a period of 24 h. Methods: This prospective trial evaluated cough and wheezing events using an auscultation monitor specially developed for this purpose with 4 integrated highly sensitive microphones, in stable and severely AECOPD patients for a period of 24 h in an inpatient setting. Results: Twenty stable COPD patients (12 male, 60%) and 20 severely exacerbated COPD patients (14 male, 70%) were analyzed. In AECOPD patients, long-term auscultation revealed a significantly higher number of wheezing epochs than stable COPD patients (591 [IQR: 145–1,645] vs. 152 [IQR: 90–400]; p = 0.021). Conversely, cough epochs did not differ between AECOPD and stable COPD patients (213 [IQR: 140–327] vs. 162 [IQR: 123–243]; p = 0.256). The Borg-dyspnea scale, CAT score, and total CCQ score each showed no correlation with wheezing frequency, while CAT and CCQ scores did correlate with coughing frequency. Conclusion: Wheezing, but not coughing, occurs more frequently in AECOPD patients than in stable COPD patients, indicating that severe wheezing is an important clinical sign of exacerbation, while coughing is not. Therefore, the patterns of wheezing and coughing, as assessed by long-term auscultation, differ in stable versus exacerbated COPD patients. [ABSTRACT FROM AUTHOR]

Background: Inhalation errors frequently occur in patients receiving inhalation treatment, which can significantly impair treatment success. While this underscores the importance of inhalation training, the role of modern web-based instructional videos has not yet been investigated. Methods: A randomized controlled trial using standardized checklists (10 items: preparation, N = 3, inhalation routine, N = 6, and closure of inhalation, N = 1) was carried out to determine the relative effects of web-based, device-specific videos versus standard personal instruction on reducing multiple (≥2) inhalation errors in severe COPD patients requiring hospitalisation. Investigators assessing inhalation errors were blinded to the intervention. Results: Multiple handling errors were recorded at baseline in 152 out of 159 patients (95.6%). Each teaching method led to a similar reduction in errors (videos: from 4.2±1.6 to 1.5±1.5 errors; personal instruction: from 3.8±1.5 to 1.3±1.6; p<0.0001), although non-inferiority of web-based video teaching could not be confirmed statistically due to an unpredictably high number of patients in both groups still making multiple handling errors (44.0% versus 40.3%, mean difference 3.7%; 95%CI [-12.0–19.4%]). Conclusion: Multiple inhalation errors regularly occur in severe COPD patients requiring hospitalisation. Web-based video teaching is capable of reducing inhalation errors. However, compared to personal instruction non-inferiority could not be established. This was due to an unexpectedly high number of patients with persisting inhalation errors despite training.

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: To investigate an outpatient setting with predefined criteria for hospitalization for patients with chronic hypercapnic COPD.Objectives: An outpatient clinic located within the hospital in the vicinity of the respiratory care unit provided predefined criteria for hospitalization of COPD patients receiving long-term NIV therapy. The results of this setting were retrospectively analysed.Methods: A total of 130 outpatient visits (80 patients) were analysed. In 93 cases (71.5%), hospital admission was not necessary, while hospitalization was performed in 37 cases (28.5%). Out of these, 7 cases with acute conditions required prompt hospitalization. Patients without hospitalization had better PaCO2 values (45.40 ± 5.27 vs. 50.05 ± 8.04,Results: p = 0.002) and Severe Respiratory Insufficiency Questionnaire Summary scores (55.54 ± 19.74 vs. 41.82 ± 19.59,p = 0.012). Outpatient control of long-term NIV in a hospital setting is feasible and has the capacity to identify stable COPD patients in whom NIV therapy is sufficient according to predefined criteria. These patients may not require hospitalization and may account for more than two thirds of cases. [ABSTRACT FROM AUTHOR]Conclusion: - Published

Background: The German guideline on long-term oxygen therapy (LTOT) was published in 2008 by the German Respiratory Society (DGP), while the British Thoracic Society (BTS) published their most recent guideline in 2015. Objectives: The aim of the present article was to highlight the major areas of consensus and disagreement in the recently published BTS and DGP guidelines on LTOT. Methods: The BTS and DGP guidelines were directly compared in terms of congruencies and differences. A critical appraisal was then performed and authors' suggestions were provided. Results: The 2 guidelines are almost congruent in 2 major areas, namely, (1) the indication criteria for LTOT in chronic obstructive pulmonary disease (COPD) patients at rest and (2) the recommended duration of LTOT over a 24-h period. However, 8 major areas in which the guidelines differ considerably were identified: (1) techniques for blood gas analysis; (2) timing of LTOT in stable patients; (3) LTOT in postexacerbation COPD patients; (4) ambulatory oxygen therapy; (5) nocturnal oxygen therapy; (6) titration of oxygen flow rates; (7) follow-up visits; and (8) LTOT for patients who still smoke. Furthermore, the BTS guideline is much more detailed, includes more references (161 vs. 71) and is more up to date than the DGP guideline. Conclusion: There are major differences between the 2 guidelines. Many of the aspects raised by the BTS guideline appear to be reasonable with regard to the current literature, clinical experience and prescription practices. However, an international consensus on LTOT is lacking. [ABSTRACT FROM AUTHOR]
