European Respiratory Society guidelines for the management of adult bronchiectasis

Bronchiectasis in adults is a chronic disorder associated with poor quality of life and frequent exacerbations in many patients. There have been no previous international guidelines.The European Respiratory Society guidelines for the management of adult bronchiectasis describe the appropriate investigation and treatment strategies determined by a systematic review of the literature.A multidisciplinary group representing respiratory medicine, microbiology, physiotherapy, thoracic surgery, primary care, methodology and patients considered the most relevant clinical questions (for both clinicians and patients) related to management of bronchiectasis. Nine key clinical questions were generated and a systematic review was conducted to identify published systematic reviews, randomised clinical trials and observational studies that answered these questions. We used the GRADE approach to define the quality of the evidence and the level of recommendations. The resulting guideline addresses the investigation of underlying causes of bronchiectasis, treatment of exacerbations, pathogen eradication, long term antibiotic treatment, anti-inflammatories, mucoactive drugs, bronchodilators, surgical treatment and respiratory physiotherapy.These recommendations can be used to benchmark quality of care for people with bronchiectasis across Europe and to improve outcomes.

Assessment of oxygenation and comorbidities improves outcome prediction in patients with community-acquired pneumonia with a low CRB-65 score.

BACKGROUND: Addition of assessment of comorbid diseases ('D') and oxygen saturation ('S') to the CRB-65 score has been recommended to improve its accuracy for risk stratification in community-acquired pneumonia (CAP). The aim of this study was to validate the resulting DS-CRB-65 score in a large cohort of patients with CAP. METHODS: A total of 4432 patients prospectively enrolled in the CAPNETZ cohort were included in this study. Predefined end points were 28-day mortality, requirement for mechanical ventilation or vasopressors (MV/VS) and requirement for MV/VS or intensive care unit admission (MV/VS/ICU). Receiver operating characteristic curve analysis was used to determine the accuracy of the CRB-65 score and the addition of D (extra-pulmonary comorbidities) and S (oxygen saturation <90% or partial pressure of oxygen <8 kPa). Binary logistic regression and the method of Hanley and McNeil were used to compare the criteria. RESULTS: The mortality rate was 4.0%, and 4.2% of patients required MV/VS and 6.6% required MV/VS/ICU. After multivariate analysis, D and S independently were added to the CRB-65 criteria for mortality prediction, but only S improved prediction of MV/VS and MV/VS/ICU (P < 0.001 for all). The area under the curve of the CRB-65 score was significantly improved by adding D and S for all end points (P < 0.02). Amongst patients who died or required MV/VS despite a CRB-65 score of 0, 64-80% would have been identified by the DS-CRB-65 score. CONCLUSIONS: The addition of assessment of oxygenation and comorbidities significantly improved the prognostic accuracy of the CRB-65 score. Consequently, the DS-CRB-65 score may have a useful role in risk stratification algorithms for CAP.

The burden of pneumococcal pneumonia - experience of the German competence network CAPNETZ.

BACKGROUND: Pneumococcal pneumonia is still an important cause of mortality. The objective of this study was to compare frequency, clinical presentation, outcome and vaccination status of patients with pneumococcal community-acquired pneumonia (CAP) to CAP due to other or no detected pathogen based on data of the German Network for community-acquired pneumonia (CAPNETZ). METHODS: Demographic, clinical and diagnostic data were recorded using standardized web-based data acquisition. Standardized microbiological sampling and work-up were conducted in each patient. RESULTS: 7400 patients with CAP from twelve clinical centers throughout Germany were included. In 2259 patients (32 %) a pathogen was identified, Streptococcus pneumonia being the most frequent (n = 676, 30 % of all patients with identified pathogens). Compared to those with non-pneumococcal pneumonia, patients with pneumococcal pneumonia were more frequently admitted to hospital (80 % vs. 66 %, p < 0.001), had higher CURB score values on admission, had more frequently pleural effusion (19 % vs. 14 %, p = 0.001) and needed more frequently oxygen insufflation (58 % vs. 44 %, p < 0.001). There was no relevant difference in overall mortality. CONCLUSIONS: Pneumococcal pneumonia was associated with a more severe clinical course demanding more medical resources as compared to non-pneumococcal pneumonia.
