Comparative Study
Prediction of infection due to antibiotic-resistant bacteria by select risk factors for health care-associated pneumonia.
Pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa now cause pneumonia in patients presenting to the hospital. The concept of health care-associated pneumonia (HCAP) attempts to capture this, but its predictive value is unclear. ⋯ Although resistance is common in HCAP, not all component criteria for HCAP convey similar risk. Simple scoring tools may facilitate more accurate identification of persons with pneumonia caused by resistant pathogens.

Preferences for life-sustaining treatment elicited in one state of health may not reflect preferences in another state of health. ⋯ Periodic reassessment of preferences is most critical for patients who desire aggressive end-of-life care or who do not have advance directives.

While some experimental and clinical research suggests that statins improve outcomes after severe infections, the evidence for pneumonia is conflicting. We examined whether preadmission statin use decreased risk of death, bacteremia, and pulmonary complications after pneumonia. ⋯ The use of statins is associated with decreased mortality after hospitalization with pneumonia.

Simplification of the revised Geneva score for assessing clinical probability of pulmonary embolism.
The revised Geneva score is a fully standardized clinical decision rule (CDR) in the diagnostic workup of patients with suspected pulmonary embolism (PE). The variables of the decision rule have different weights, which could lead to miscalculations in an acute setting. We have validated a simplified version of the revised Geneva score. ⋯ This study suggests that simplification of the revised Geneva score does not lead to a decrease in diagnostic accuracy and clinical utility, which should be confirmed in a prospective study.
