Purpose: The objective of this study was to update the incidence and natural history of empyema in patients admitted to hospital with community-acquired pneumonia (CAP).
Methods: A prospective population-based study of 3675 patients with a diagnosis of CAP was carried out. Patients were classified as "definite empyema" based on one or more of the following criteria: presence of microorganisms in pleural fluid Gram stain or culture, pleural pH less than 7.
Objective: To determine factors associated with the length of stay (LOS) for patients with suspected community-acquired pneumonia (CAP) who required hospitalization for treatment.
Study Design: The authors studied a population-based prospective cohort of 2,757 adults with suspected CAP who were admitted over a two-year period. Logistic regression, multiple linear regression, and classification and regression trees were used to determine the factors associated with LOS.
Objectives: To determine the prevalence of aspiration pneumonia and to compare the features and risk factors for this entity in patients from continuing care facilities (CCFs) and the community who were admitted to the hospital with pneumonia.
Design: Prospective population-based study.
Setting: Six hospitals in Capital Health Region (Edmonton), Alberta, Canada.
Purpose: To describe the natural history of community-acquired pneumonia in the subset of a large cohort of patients at low risk for mortality who were admitted to the hospital.
Methods: Prospective observational study of all patients at low risk for mortality (risk classes I and II) who presented to 6 hospitals and 1 emergency department in Edmonton, Alberta, Canada with a diagnosis of possible community-acquired pneumonia from November 15, 2000, to November 14, 2002.
Results: A total of 586/3065 (19.
Bacteremic pneumococcal pneumonia (BPP) is an important disease that should be frequently re-evaluated due to changes in demographics and recommended treatment. We conducted a prospective study from 2000 to 2002 in adults aged 17 years and over who presented to any of 6 hospitals and 1 freestanding emergency room in Edmonton, Alberta, with signs and symptoms compatible with pneumonia, a chest radiograph interpreted as pneumonia by the attending physician, and a positive blood culture for Streptococcus pneumoniae. We identified 129 patients with BPP, for an overall incidence of 9.

Design: Prospective study from November 15, 2000, to November 14, 2002.
Setting: Six hospitals in the Edmonton, Canada, area.
Patients aged 17 years and older who presented to seven emergency departments in Edmonton, Alberta over a two-year period with community-acquired pneumonia (n=8144) were studied. The admission rates were 271/100,00 and 296/100,000 persons for year 1 and year 2 of the study, respectively. The admission rate increased with increasing age, peaking at 4639/100,000/year for those 90 years of age and older.

Methods: We studied a population-based cohort of 2706 adults who were admitted with suspected pneumonia and managed using a clinical pathway. We stratified patients by presence or absence of radiograph-confirmed pneumonia, and compared their characteristics and in-hospital mortality.
