For emergency medical services with low VF survival rates (<20%), early rhythm analysis improves survival, whereas in services where VF survival rates are high (>20%) delayed rhythm analysis with focus on immediate CPR instead improves survival.

Multicenter Study Observational Study
Extension Test and Ossal Point Tenderness Cannot Accurately Exclude Significant Injury in Acute Elbow Trauma.
Elbow injury is a common presentation at the emergency department (ED). There are no guidelines indicating which of these patients require radiography, whereas clinical decision rules for other limb injuries are widely accepted and resulted in less radiography and reduced waiting times. We aim to identify clinical signs that can be used to predict the need for radiography in elbow injury. ⋯ In contrast with previous studies, ours shows that in acute elbow injury, the extension test alone or in combination with point tenderness assessment does not safely rule out clinically significant injury. Interobserver variability was substantial. We would not recommend the use of the extension test (+/- point tenderness assessment) as a clinical decision rule to guide radiologic diagnostics in acute elbow trauma.

Ondansetron and the Risk of Cardiac Arrhythmias: A Systematic Review and Postmarketing Analysis.
To explore the risk of cardiac arrhythmias associated with ondansetron administration in the context of recent recommendations for identification of high-risk individuals. ⋯ Current evidence does not support routine ECG and electrolyte screening before single oral ondansetron dose administration to individuals without known risk factors. Screening should be targeted to high-risk patients and those receiving ondansetron intravenously.
