EXECUTIVE SUMMARY Improving the care of adult patients with community-acquired pneumonia (CAP) has been the focus of many different organizations, and several have developed guidelines for management of CAP. Two of the most widely referenced are those of the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS). In response(More)
Oxygen (O2) has been reported to improve exercise tolerance in some patients with chronic obstructive pulmonary disease (COPD) despite only mild resting hypoxemia (PaO2 greater than 60 mm Hg). To confirm these prior studies and evaluate potential mechanisms of benefit, we measured dyspnea scores by numeric rating scale during cycle ergometry endurance(More)
The goal of this study was to determine the accuracy and the impact of 5 different claims-based pneumonia definitions. Three International Classification of Diseases, Version 9, (ICD-9), and 2 diagnosis-related group (DRG)-based case identification algorithms were compared against an independent, clinical pneumonia reference standard. Among 10748 patients,(More)
PURPOSE We developed a pneumonia guideline at Intermountain Health Care that included admission decision support and recommendations for antibiotic timing and selection, based on the 1993 American Thoracic Society guideline. We hypothesized that guideline implementation would decrease mortality. SUBJECTS AND METHODS We included all immunocompetent(More)
To determine the feasibility of noninvasive determination of right ventricular systolic pressure (RVSP) during a graded-exercise protocol, saline contrast-enhanced Doppler echocardiography of tricuspid insufficiency was performed in 36 patients with chronic lung disease and 12 normal controls. In the patients with chronic pulmonary disease, symptom-limited,(More)
BACKGROUND Novel 2009 influenza A(H1N1) infection has significantly affected ICUs. We sought to characterize our region's clinical findings and demographic associations with ICU admission due to novel A(H1N1). METHODS We conducted an observational study from May 19, 2009, to June 30, 2009, of descriptive clinical course, inpatient mortality, financial(More)
BACKGROUND We previously reported decreased mortality following implementation of a community-acquired pneumonia guideline derived from specialty society recommendations. However, patients with respiratory failure and sepsis from pneumonia were not included, adjustment for comorbidities was limited, and no guideline compliance data were available. We also(More)
OBJECTIVES Validate the Infectious Disease Society of America/American Thoracic Society 2007 (IDSA/ATS 2007) criteria for predicting severe community-acquired pneumonia (SCAP) and evaluate a health-services definition for SCAP. DESIGN Retrospective cohort study. SETTING LDS Hospital, an academic tertiary care facility in the western United States. (More)
STUDY OBJECTIVE Ewig et al. proposed a new definition of severe community-acquired pneumonia in 1999, which was adopted by the American Thoracic Society in 2001. We evaluated this definition in an independent population of emergency department patients. DESIGN We compared the 2001 American Thoracic Society definition of severe community-acquired pneumonia(More)
