Multicenter Study Comparative Study
FEV(1)/FEV(6) to diagnose airflow obstruction. Comparisons with computed tomography and morbidity indices.
FVC is a difficult maneuver for many patients, and forced expiratory volume in 6 seconds (FEV6) has been proposed as a surrogate for FVC for the diagnosis of chronic obstructive pulmonary disease (COPD). Previous studies have performed head-to-head comparisons of these thresholds but did not examine their relationships with structural lung disease, symptoms, or exacerbations. ⋯ FEV1/FEV6 can be substituted for FEV1/FVC in diagnosing airflow obstruction and may better predict COPD-related pathology and morbidity.

What is known about physician handoffs is almost entirely limited to resident practice, but attending physicians ultimately determine care plans and goals of care. This study sought to understand what is unique about attending intensivist handoffs, to identify perceptions of the ideal content and format of intensive care unit (ICU) attending handoffs, and to understand how ideal and reported practices are aligned in the delivery of care. ⋯ A national sample of academic intensivists identified common ideal attributes of attending handoffs, yet their reported handoff practices varied widely. Ideal handoff practices may form the basis of future interventions to improve communication between intensivists.

Introduction of sedation protocols has been associated with improved patient outcomes. It is not known if an update to an existing high-quality sedation protocol, featuring increased patient assessment and reduced benzodiazepine exposure, is associated with improved patient process and outcome quality metrics. ⋯ Implementation of an updated ICU analgesia, sedation, and delirium protocol was associated with an increase in RASS and CAM-ICU assessment and documentation; reduced hourly benzodiazepine dose; and decreased delirium and median durations of mechanical ventilation, ICU stay, and hospitalization.

Randomized Controlled Trial
Performance of the EXAcerbations of chronic pulmonary disease tool patient-reported outcome measure in three clinical trials of chronic obstructive pulmonary disease.
The EXAcerbations of Chronic Pulmonary Disease Tool (EXACT) is a patient-reported outcome measure to standardize the symptomatic assessment of chronic obstructive pulmonary disease exacerbations, including reported and unreported events. The instrument has been validated in a short-term study of patients with acute exacerbation and stable disease; its performance in longer-term studies has not been assessed. ⋯ Data generated through the EXACT offers insight into the symptomatic nature of MTEs and the frequency, severity, and duration of unreported symptom-defined events. Clinical trials registered with www.clinicaltrials.gov (MPEX: NCT00739648; AZ 1: NCT00949975; AZ 2: NCT01023516).

IFN-γ release assays (IGRAs) including the QuantiFERON-TB gold in-tube test (QFT-GIT) are increasingly used in place of the tuberculin skin test (TST) in surveillance programs for Mycobacterium tuberculosis infection in the United States. However, data on conversions, reversions, and predictive value of QFT in such programs for health care workers (HCWs) are limited. ⋯ Poor IGRA reproducibility and a low predictive value of QFT-GIT conversions indicate that QFT-GIT with current interpretation criteria should not be used for serial screening of U.S. HCWs. Negative TSTs have higher reproducibility than QFT-GIT for serial testing of HCWs in low tuberculosis incidence settings.
