Review Case Reports
The mortality benefit threshold for patients with suspected pulmonary embolism.
The mortality benefit for pulmonary embolism (PE) is the difference in mortality between treated and untreated patients. The mortality benefit threshold is the mortality benefit above which testing for a condition should be initiated and below which it should not. To illustrate this concept, the authors developed a decision model to estimate the mortality benefit threshold at several pretest probabilities for low-risk emergency department (ED) patients with possible PE and compare those thresholds with contemporary management of PE in the United States and what is known and not known about treatment benefits with anticoagulation. ⋯ The mortality benefit threshold for initiating PE testing is very high at low pretest probabilities of PE, which should be considered by clinicians in their diagnostic approach to PE in the ED. The mortality benefit threshold is a novel way of exploring the benefits and risks of ED-based testing, particularly in situations like PE where testing (i.e., CT use) carries real risks and the benefits of treatment are uncertain.

Comparative Study
Patient understanding of emergency department discharge instructions: where are knowledge deficits greatest?
Many patients are discharged from the emergency department (ED) with an incomplete understanding of the information needed to safely care for themselves at home. Patients have demonstrated particular difficulty in understanding post-ED care instructions (including medications, home care, and follow-up). The objective of this study was to further characterize these deficits and identify gaps in knowledge that may place the patient at risk for complications or poor outcomes. ⋯ Patients demonstrate the most frequent knowledge deficits for home care and return instructions, raising significant concerns for adherence and outcomes.

Multicenter Study Comparative Study
Practice patterns in asthma discharge pharmacotherapy in pediatric emergency departments: a pediatric emergency research Canada study.
The objective was to examine utilization of β2 agonists via metered dose inhalers with oral and inhaled corticosteroids (ICS) at discharge in children with acute asthma. ⋯ The overwhelming majority of children discharged from Canadian pediatric EDs with acute asthma are prescribed inhaled albuterol via MDIs. Although the corticosteroid use at discharge is higher than previously reported, utilization of new prescriptions for ICS may not be optimal. Children presenting during daytime to EDs receiving intensive stabilization are more likely to receive the albuterol/oral steroid/ICS combination.

Randomized Controlled Trial Multicenter Study Comparative Study
Validation of a clinical prediction model for early admission to the intensive care unit of patients with pneumonia.
The Risk of Early Admission to the Intensive Care Unit (REA-ICU) index is a clinical prediction model that was derived based on 4,593 patients with community-acquired pneumonia (CAP) for predicting early admission to the intensive care unit (ICU; i.e., within 3 days following emergency department [ED] presentation). This study aimed to validate the REA-ICU index in an independent sample. ⋯ The REA-ICU index reliably stratifies CAP patients into four categories of increased risk for early ICU admission within 3 days following ED presentation. Further research is warranted to determine whether inflammatory biomarkers may improve the performance of this clinical prediction model.

Review Case Reports
A model for emergency department end-of-life communications after acute devastating events--part I: decision-making capacity, surrogates, and advance directives.
Making decisions for a patient affected by sudden devastating illness or injury traumatizes a patient's family and loved ones. Even in the absence of an emergency, surrogates making end-of-life treatment decisions may experience negative emotional effects. Helping surrogates with these end-of-life decisions under emergent conditions requires the emergency physician (EP) to be clear, making medical recommendations with sensitivity. ⋯ EPs should also help the surrogate and family understand that palliative care addresses comfort needs of the patient including adequate treatment for pain, dyspnea, or anxiety. Part I of this communications model reviews determination of decision-making capacity, surrogacy laws, and advance directives, including legal definitions and application of these steps; Part II (which will appear in a future issue of AEM) covers communication moving from resuscitative to end-of-life and palliative treatment. EPs should recognize acute devastating illness or injuries, when appropriate, as opportunities to initiate end-of-life discussions and to implement shared decisions.
