Proposed quality indicators and recommended standard reporting items in performance of EBUS bronchoscopy: An official World Association for Bronchology and Interventional Pulmonology Expert Panel consensus statement.

BACKGROUND: Since their introduction, both linear and radial endobronchial ultrasound (EBUS) have become an integral component of the practice of Pulmonology and Thoracic Oncology. The quality of health care can be measured by comparing the performance of an individual or a health service with an ideal threshold or benchmark. The taskforce sought to evaluate quality indicators in EBUS bronchoscopy based on clinical relevance/importance and on the basis that observed significant variation in outcomes indicates potential for improvement in health care outcomes. METHODS: A comprehensive literature review informed the composition of a comprehensive list of candidate quality indicators in EBUS. A multiple-round modified Delphi consensus process was subsequently performed with the aim of reaching consensus over a final list of quality indicators and performance targets for these indicators. Standard reporting items were developed, with a strong preference for items where evidence demonstrates a relationship with quality indicator outcomes. RESULTS: Twelve quality Indicators are proposed, with performance targets supported by evidence from the literature. Standardized reporting items for both radial and linear EBUS are recommended, with evidence supporting their utility in assessing procedural outcomes presented. CONCLUSION: This statement is intended to provide a framework for individual proceduralists to assess the quality of EBUS they provide their patients through the identification of clinically relevant, feasible quality measures. Emphasis is placed on outcome measures, with a preference for consistent terminology to allow communication and benchmarking between centres.

Angiopoietin-2 Levels as Predictors of Outcome in Mechanically Ventilated Patients with Acute Respiratory Distress Syndrome.

Pulmonary endothelium dysfunction is a key characteristic of ARDS. The aim of this study was to investigate endothelium-derived markers, such as angiopoietin-2 (Ang-2) and endothelial cell-specific molecule-1 (endocan), at the vascular and alveolar compartments as outcome predictors in ARDS. Fifty-three consecutive ARDS patients were studied. The primary outcome was 28-day mortality. Secondary endpoints were days of unassisted ventilation and days with organ failure other than ARDS, during the 28-day study period. Nonsurvivors presented higher lung injury scores and epithelial lining fluid (ELF) Ang-2 levels compared to survivors, with no significant differences in plasma Ang-2, endocan, and protein C concentrations between the two groups. In logistic regression analysis, ELF Ang-2 levels > 705 pg/ml were the only independent variable for 28-day mortality among the previous four. Plasma endocan values > 13 ng/pg were the only parameter predictive against days of unassisted ventilation during the 28-day study period. Finally, lung injury score > 2.25 and ELF Ang-2 levels > 705 pg/ml were associated with increased number of days with organ failure, other than ARDS. Our findings suggest that Ang-2 levels are increased in the alveolar compartment of ARDS patients, and this may be associated both with increased mortality and organ failure besides lung.

Life-threatening aortic thrombosis in a trauma patient homozygous for factor V Leiden mutation: Case report.

We report a case of near fatal aortic thrombosis in a trauma patient homozygous for mutation of Factor V Leiden. He responded well to vascular surgery and intensive care unit management and was discharged successfully from the hospital one month later.

General prognostic scores in outcome prediction for cancer patients admitted to the intensive care unit.

BACKGROUND: Intensivists and nursing staff are often reluctant to admit patients with cancer to the intensive care unit even though these patients' survival rate has improved since the 1980s. OBJECTIVE: To identify factors associated with mortality in cancer patients admitted to the intensive care unit and to assess and compare the effectiveness of 3 general prognostic models: the Acute Physiology and Chronic Health Evaluation (APACHE) II, the Simplified Acute Physiology Score (SAPS II), and the Sequential Organ Failure Assessment (SOFA). METHODS: A prospective observational cohort study was performed in 2 general intensive care units. Discrimination was assessed by using area under the receiver operating characteristic curves, and calibration was evaluated by using Hosmer-Lemeshow goodness-of-fit tests. RESULTS: A total of 126 patients were included during a 3-year period. The observed mortality was 46.8%. All 3 general models showed excellent discrimination (area under the curve >0.8) and good calibration (P = .17, .14, and .22 for APACHE II, SAPS II, and SOFA, respectively). However, discrimination was significantly better with APACHE II scores than with SOFA scores (P = .02). Multivariate analyses indicated that independent of the 3 severity-of-illness scores, unfavorable risk factors for mortality included a patient's preadmission performance status, source of admission (internal medicine vs surgery department), and the presence of septic shock, infection, or anemia. Combining SOFA and SAPS II scores with these variables created prognostic models with improved calibration and discrimination. CONCLUSIONS: The general prognostic models seem fairly accurate in the prediction of mortality in critically ill cancer patients in the intensive care unit.
