BACKGROUND There is considerable variability in rates of hospitalization of patients with community-acquired pneumonia, in part because of physicians' uncertainty in assessing the severity of illness at presentation. METHODS From our analysis of data on 14,199 adult inpatients with community-acquired pneumonia, we derived a prediction rule that stratifies(More)
CONTEXT Although certain media exposures have been linked to the presence of psychiatric conditions, few studies have investigated the association between media exposure and depression. OBJECTIVE To assess the longitudinal association between media exposure in adolescence and depression in young adulthood in a nationally representative sample. DESIGN(More)
BACKGROUND Legionella is a common cause of bacterial pneumonia. Community-acquired [CAL] and hospital-acquired legionellosis [HAL] may have different presentations and outcome. We aimed to compare clinical characteristics and examine predictors of mortality for CAL and HAL. METHODS We identified hospitalized cases of legionellosis in 4 Danish counties(More)
Rationale: An objective and simple prognostic model for patients with pulmonary embolism could be helpful in guiding initial intensity of treatment. Objectives: To develop a clinical prediction rule that accurately classifies patients with pulmonary embolism into categories of increasing risk of mortality and other adverse medical outcomes. Methods: We(More)
BACKGROUND Although practice guidelines recommend outpatient care for selected, haemodynamically stable patients with pulmonary embolism, most treatment is presently inpatient based. We aimed to assess non-inferiority of outpatient care compared with inpatient care. METHODS We undertook an open-label, randomised non-inferiority trial at 19 emergency(More)
BACKGROUND: Despite strong evidence of the effectiveness of influenza vaccination, immunization rates have reached a plateau that is below the 2010 national goals. Our objective was to identify facilitators of, and barriers to, vaccination in diverse groups of older patients. METHODS: A survey was conducted in 2000 by computer-assisted telephone(More)
BACKGROUND Optimal management of acute pulmonary embolism (PE) requires medical expertise, diagnostic testing, and therapies that may not be available consistently throughout the entire week. We sought to assess whether associations exist between weekday or weekend admission and mortality and length of hospital stay for patients hospitalized with PE. (More)
INTRODUCTION To identify risk factors for early (< three days) intensive care unit (ICU) admission of patients hospitalised with community-acquired pneumonia (CAP) and not requiring immediate ICU admission, and to stratify the risk of ICU admission on days 1 to 3. METHODS Using the original data from four North American and European prospective(More)
