Multicenter Study
Relationship between pain, opioid treatment, and delirium in older emergency department patients.
Emergency department (ED) stay and its associated conditions (immobility, inadequate hydration and nutrition, lack of stimulation) increase the risk of delirium in older patients. Poorly controlled pain and paradoxically opioid pain treatment have also been identified as triggers for delirium. The aim of this study was to assess the relationship between pain, opioid treatment, and delirium in older ED patients. ⋯ Severe pain, not opioids, is associated with the development of delirium during ED stay. Adequate pain control during the hospital stay may contribute to a decrease in delirium episodes.

Multicenter Study
Myocardial Infarction Can Be Safely Excluded by High-sensitivity Troponin I Testing 3 Hours After Emergency Department Presentation.
The accuracy and speed by which acute myocardial infarction (AMI) is excluded are an important determinant of emergency department (ED) length of stay and resource utilization. While high-sensitivity troponin I (hsTnI) >99th percentile (upper reference level [URL]) represents a "rule-in" cutpoint, our purpose was to evaluate the ability of the Beckman Coulter hsTnI assay, using various level-of-quantification (LoQ) cutpoints, to rule out AMI within 3 hours of ED presentation in suspected acute coronary syndrome (ACS) patients. ⋯ Patients presenting >3 hours after the onset of suspected ACS symptoms, with at least two Beckman Coulter Access hsTnI < URL and at least one of which is below either the 10 or the 20% LoQ, had a 100% NPV for AMI. Two hsTnI values 1 to 3 hours apart with both < URL, but also >LoQ had inadequate sensitivity and NPV.
