Echocardiography performed during cardiac arrest that demonstrates an absence of cardiac activity harbors a significantly lower (but not zero) likelihood that a patient will experience ROSC. In selected patients with a higher likelihood of survival from cardiac arrest at presentation, based on established predictors of survival, echo should not be the sole basis for the decision to cease resuscitative efforts. Echo should continue to be used only as an adjunct to clinical assessment in predicting the outcome of resuscitation for cardiac arrest.

CLINICIAN'S CAPSULE What is known about the topic? Current diagnostic tools for heart failure in the emergency department (ED) have limited accuracy and often lead to delays in management. What did this study ask? What is the accuracy of early bedside lung ultrasound in the diagnosis of acute decompensated heart failure? What did this study find? This meta-analysis found that the sensitivity and specificity of bedside lung US in ADHF is 82.5% and 83.6%, respectively. Why does this study matter to clinicians? The implementation of early bedside lung US in the ED may lead to more accurate and timely diagnoses of ADHF.

The rapid development and updates of mobile medical resource applications (apps) highlight the need for an evaluation tool to assess the content of these resources. The purpose of the study was to develop and test a new evaluation rubric for medical resource apps. The evaluation rubric was designed using existing literature and through a collaborative effort between a hospital and an academic librarian. Testing found scores ranging from 23% to 88% for the apps. The evaluation rubric proved able to distinguish levels of quality within each content component of the apps, demonstrating potential for standardization of medical resource app evaluations.
