Background: The number of long-term ventilated patients in out-of-hospital intensive care (OIC) in Germany has risen sharply in recent years. Due to financial disincentives, structural care deficits and resource bottlenecks, there is an increasing risk of inadequate care. In 2020, the Intensive Care and Rehabilitation Strengthening Act (IPReG) was therefore passed by legislators with the aim of improving OIC. This study examines the opportunities and challenges of the IPReG with regard to the care of long-term ventilated patients in OIC from the perspective of payers and healthcare policy., Materials and Methods: A qualitative interview study was conducted as part of the process evaluation of the multicenter study PRiVENT (Prevention of invasive Ventilation). Using semi-structured, guideline-based individual interviews, health policy actors and representatives of statutory health insurers were asked about the IPReG., Results: In all, 11 health policymakers and 12 representatives of statutory health insurance companies took part in the interviews. Both interview groups showed a positive attitude towards the IPReG and expressed the expectation of added value for the outpatient care of long-term ventilated patients. The current remuneration regulations for weaning and the assessment of weaning potential in the OIC were criticized, among other things., Conclusion: The IPReG provides a legal basis for improving OIC, but there is still room for improvement in its current version. The evaluation planned by legislators should be used to identify potential weaknesses and make appropriate adjustments., Competing Interests: Einhaltung ethischer Richtlinien.

Background: To date there are no data on sex aspects evaluating outcomes of interventional pneumology (IP). Our aim was to investigate sex differences in transbronchial lung cryobiopsy (TBLC) outcomes in the diagnosis of interstitial lung disease (ILD)., Methods: All consecutive (TBLC)s performed for ILD evaluation between Nov 17 and Dec 21 at a tertiary referral center for ILDs and IP were analyzed. The indication for the procedure was determined by a multidisciplinary discussion (MDD). Final results including bronchoalveolar lavage (BAL) and histology were discussed in a 2nd MDD and outcomes and procedure related complications were assessed., Results: TBLC was performed in 406 patients (38.4 % female/67.8 years/FVC 76.8 %). Among 32 interventionalists, 16 females performed 53 % of interventions. Females had longer procedure times (29.9 vs. 26.6 min, p = 0.046), used fluoroscopy more often (76.7 vs. 50.3 %, p < 0.001) and obtained more samples (3.6 vs. 3.2, p = 0.021) than their male counterparts. No difference was found for major bleeding or pneumothorax. MDD was able to conclude on a diagnosis in 88.4 % of interventions performed by women and in 78.5 % performed by men (p = 0.010). In a multivariate analysis, female gender (OR 1.93) and lower FVC% values (OR 0.98) were significantly associated with diagnostic yield, whereas the number of biopsies, professional experience, use of fluoroscopy or antiplatelet drugs were not relevant., Conclusion: The results of this study strengthen the role of women in endoscopy and may help to motivate women to pursue a career in IP., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: FCT received research funding from Octapharma Pharmazeutika Produktionsgeselltschaft m.b.H. to conduct this study; the funder had no influence on the evaluation and interpretation of the data.

Background: Established structured weaning approaches, which are effective for patients in simple and difficult weaning, are often not appropriate for patients undergoing prolonged weaning. Addressing the complexity of weaning failure requires personalized precision medicine. The therapeutic concept of treatable traits (TTs) has been proposed as a new paradigm for the management of chronic respiratory diseases. It is based on a multidimensional assessment of specific characteristics, which can be addressed by specific interventions that go beyond traditional diagnostic criteria. The concept is increasingly adopted for other complex diseases., Summary: This is a narrative review and an expert opinion on the development of a concept of TTs for patients undergoing prolonged weaning. The proposed TTs are based on a systematic review of risk factors for prolonged weaning, an analysis of claims data to assess risk factors within 96 h of IMV onset and data from the WEAN SAFE study. A multidisciplinary team identified clinically important TTs and determined appropriate interventions. The following TTs have been identified: airway disorders and complications associated with tracheostomy or intubation, such as airway obstruction, strictures or tracheomalacia, infectious aspects, anxiety, depression, delirium, post-traumatic stress disorder, anemia, pulmonary and cardio-renal disease. The multidimensional holistic approach also includes tailored sedation and pain management, nutritional therapy, early mobilization, and physiotherapy., Key Message: We propose a framework of relevant considerations for a multidimensional approach to the management of patients undergoing prolonged weaning that supports the regain of respiratory capacity, reduces the respiratory load, and thus could resolve the respiratory workload imbalance., (© 2024 S.

Background: In recent years, the importance of sex as a factor influencing medical care has received increasing attention in the field of intensive care medicine. The objective of this study was to examine the influence of sex in prolonged weaning., Methods: A retrospective analysis of patients undergoing prolonged weaning at Thoraxklinik, University Hospital Heidelberg between 12/08 and 12/23 was conducted. Patients with neuromuscular diseases were excluded from the analyses. The risk factors for weaning failure in men and women were identified through stepwise cox-regression analyses., Results: A total of 785 patients were included, of whom 313 (39.9%) were women. 77.9% of the women and 75.4% of the men were successfully weaned from invasive ventilation. In group comparisons and multivariable analyses, sex was not found to be a risk factor for weaning failure. Cox regression analyses were performed separately for both sexes on the outcome of weaning failure, adjusting for relevant covariates. The results indicated that age ≥ 65 years (HR 2.38, p < 0.001) and the duration of IMV before transfer to the weaning centre (HR 1.01/day, p < 0.001) were independent risk factors in men. In women, however, the duration of IMV before transfer (HR 1.01, p < 0.001), previous non-invasive ventilation (HR 2.9, p 0.005), the presence of critical illness polyneuropathy (HR 1.82; p = 0.040) and delirium (HR 2.50, p = 0.017) were identified as relevant risk factors. In contrast delirium was associated with a favourable weaning outcome in men (HR 0.38, p = 0.020) and nosocomial pneumonia as a reason for prolonged weaning in women (HR 0.43; p = 0.032)., Conclusion: The analyses indicate that there are sex-based differences in the risk factors associated with weaning failure. Further studies, ideally prospective, should confirm these findings to assess whether sex is a factor that should be taken into account to improve weaning outcomes., (© 2024. The Author(s).)

Introduction: The diaphragm thickening fraction (DTF) may be a valuable tool for estimating respiratory effort in non-invasive ventilation. The primary aim of this physiological study is the investigation of the correlation of DTF with oesophageal pressure swings (ΔP oes ). A secondary aim is to assess the discriminatory capacity of the index tests for different exercise loads., Methods: Healthy volunteers underwent spontaneous breathing and non-invasive ventilation with a sequence of different respirator settings. The first sequence was carried out at rest. The same sequence was repeated twice, with additional ergometry of 25 and 50 Watts, respectively. DTF and ΔP oes were measured during each ventilation configuration., Results: 23 individuals agreed to participate. DTF was moderately correlated with ΔP oes (repeated measures correlation ρ = 0.410, p < 0.001). Both ΔP oes and DTF increased consistently with exercise loading in every ventilation configuration, however ΔP oes showed greater discriminatory capacity., Conclusion: DTF was moderately correlated with ΔP oes and could discriminate reasonably between exercise loads in a small cohort of non-invasively ventilated healthy subjects. While it may not accurately reflect the absolute respiratory effort, DTF might help titrating individual non-invasive respiratory support. Further investigations are needed to test this hypothesis., Trial Registration: This study was not prospectively registered., (© 2024. The Author(s).)

Background: The evidence regarding effects of statins on exacerbation risk in COPD remains controversial. Previous studies often excluded patients with cardiovascular comorbidities despite their high prevalence in COPD and role for exacerbations. Based on the cardioprotective properties of statins, we hypothesised that statins may reduce the risk of exacerbations especially in patients with cardiovascular comorbidities., Methods: One thousand eight hundred eighty seven patients of the German COPD cohort COSYCONET (COPD and Systemic Consequences Comorbidities Network) of GOLD grades 1-4 (37.8% female, mean age 64.78 ± 8.3) were examined at baseline and over a period of 4.5 years for the occurrence of at least one exacerbation or severe exacerbation per year in cross-sectional and longitudinal analyses adjusted for age, gender, BMI, GOLD grade and pack-years. Due to their collinearity, various cardiovascular diseases were tested in separate analyses, whereby the potential effect of statins in the presence of a specific comorbidity was tested as interaction between statins and comorbidity. We also identified patients who never took statins, always took statins, or initiated statin intake during the follow-up., Results: One thousand three hundred six patients never took statins, 31.6% were statin user, and 12.9% initiated statins during the follow-up. Most cardiovascular diseases were significantly (p < 0.05)may associated with an increased risk of COPD exacerbations, but in none of them the intake of statins was a significant attenuating factor, neither overall nor in modulating the increased risk linked to the specific comorbidities. The results of the cross-sectional and longitudinal analyses were consistent with each other, also those regarding at least 1 exacerbation or at least 1 severe exacerbation per year., Conclusion: These findings complement the existing literature and may suggest that even in patients with COPD, cardiovascular comorbidities and a statin therapy that targets these comorbidities, the effects of statins on exacerbation risk are either negligible or more subtle than a reduction in exacerbation frequency., Trial Registration: Trial registration ClinicalTrials.gov, Identifier: NCT01245933.

Background: PRiVENT (PRevention of invasive VENTilation) is an evaluation of a bundle of interventions aimed at the prevention of long-term invasive mechanical ventilation. One of these elements is an e-learning course for healthcare professionals to improve weaning expertise. The aim of our analysis is to examine the implementation of the course in cooperating intensive care units., Methods: The course has been developed through a peer review process by pulmonary and critical care physicians in collaboration with respiratory therapists, supported by health services researchers and a professional e-learning agency. The e-learning platform "weLearn" was made available online to participating healthcare professionals. Feedback on the e-learning programme was obtained and discussed in quality circles (QCs). We measured the acceptance and use of the programme through access statistics., Results: The e-learning course "Joint Prevention of Long-Term Ventilation" consists of 7 separate modules with practice-oriented training units as well as a cross-module area and corresponding interactive case studies. Users can receive 23 CME (continuing medical education) credits. The platform was released on July 1, 2021. By June 28, 2023, 214 users from 33 clinics had registered. Most users (77-98%) completed the modules, thus performing well in the test, where 90-100% passed. In the QCs, the users commended the structure and practical relevance of the programme, as well as the opportunity to earn CME credits., Conclusion: Especially for medical staff in intensive care units, where continuous training is often a challenge during shift work, e-learning is a useful supplement to existing medical training., Trial Registration: The PRiVENT study is registered at ClinicalTrials.gov (NCT05260853) on 02/03/2022., (© 2024.

Background: Although multidrug-resistant bacteria (MDR) are common in patients undergoing prolonged weaning, there is little data on their impact on weaning and patient outcomes., Methods: This is a retrospective analysis of consecutive patients who underwent prolonged weaning and were at a university weaning centre from January 2018 to December 2020. The influence of MDR colonisation and infection on weaning success (category 3a and 3b), successful prolonged weaning from invasive mechanical ventilation (IMV) with or without the need for non-invasive ventilation (NIV) compared with category 3c (weaning failure 3cI or death 3cII) was investigated. The pathogen groups considered were: multidrug-resistant gram-negative bacteria (MDRGN), methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus spp. (VRE)., Results: A total of 206 patients were studied, of whom 91 (44.2%) showed evidence of MDR bacteria (32% VRE, 1.5% MRSA and 16% MDRGN), with 25 patients also meeting the criteria for MDR infection. 70.9% of the 206 patients were successfully weaned from IMV, 8.7% died. In 72.2% of cases, nosocomial pneumonia and other infections were the main cause of death. Patients with evidence of MDR (infection and colonisation) had a higher incidence of weaning failure than those without evidence of MDR (48% vs. 34.8% vs. 21.7%). In multivariate analyses, MDR infection (OR 4.9, p = 0.004) was an independent risk factor for weaning failure, along with male sex (OR 2.3, p = 0.025), Charlson Comorbidity Index (OR 1.2, p = 0.027), pH (OR 2.7, p < 0.001) and duration of IMV before admission (OR 1.01, p < 0.001). In addition, MDR infection was the only independent risk factor for death (category 3cII), (OR 6.66, p = 0.007)., Conclusion: Patients with MDR infection are significantly more likely to die during the weaning process. There is an urgent need to develop non-antibiotic approaches for the prevention and treatment of MDR infections as well as clinical research on antibiotic stewardship in prolonged weaning as well as in ICUs., (© 2024.

Background: Long-term invasive mechanical ventilation (IMV) is a major burden for those affected and causes high costs for the health care system. Early risk assessment is a prerequisite for the best possible support of high-risk patients during the weaning process. We aimed to identify risk factors for long-term IMV within 96 h (h) after the onset of IMV., Methods: The analysis was based on data from one of Germany's largest statutory health insurance funds; patients who received IMV ≥ 96 h and were admitted in January 2015 at the earliest and discharged in December 2017 at the latest were analysed. OPS and ICD codes of IMV patients were considered, including the 365 days before intubation and 30 days after discharge. Long-term IMV was defined as evidence of invasive home mechanical ventilation (HMV), IMV ≥ 500 h, or readmission with (re)prolonged ventilation., Results: In the analysis of 7758 hospitalisations, criteria for long-term IMV were met in 38.3% of cases, of which 13.9% had evidence of HMV, 73.1% received IMV ≥ 500 h and/or 40.3% were re-hospitalised with IMV. Several independent risk factors were identified (p < 0.005 each), including pre-diagnoses such as pneumothorax (OR 2.10), acute pancreatitis (OR 2.64), eating disorders (OR 1.99) or rheumatic mitral valve disease (OR 1.89). Among ICU admissions, previous dependence on an aspirator or respirator (OR 5.13), and previous tracheostomy (OR 2.17) were particularly important, while neurosurgery (OR 2.61), early tracheostomy (OR 3.97) and treatment for severe respiratory failure such as positioning treatment (OR 2.31) and extracorporeal lung support (OR 1.80) were relevant procedures in the first 96 h after intubation., Conclusion: This comprehensive analysis of health claims has identified several risk factors for the risk of long-term ventilation. In addition to the known clinical risks, the information obtained may help to identify patients at risk at an early stage.
