Review Meta Analysis
Intraosseous access in adults in cardiac arrest: a systematic review and meta-analysis.
To evaluate the efficacy of intraosseous access versus venous access in out-of-hospital cardiac arrest in terms of return of spontaneous circulation (ROSC) and survival to hospital discharge with or without favorable neurologic status. ⋯ Intraosseous access in out-of-hospital cardiac arrest is related to poorer outcomes in terms of ROSC and survival at hospital discharge.

To analyze clinical data and electrocardiographic (ECG) findings obtained during the initial evaluation of patients with nontraumatic chest pain (NTCP). To explore associations between these findings and the initial and final diagnoses of acute coronary syndrome (ACS). To assess which variables initially over- or underestimate risk ACS. ⋯ The variables traditionally used to warn of ACS in emergency patients with NTCP identify individuals likely to be initially and finally diagnosed with ACS. However, some of these variables overestimate or underestimate the risk of a final ACS diagnosis. Emergency medicine physicians should be aware of variables associated with underestimation of risk.

Randomized Controlled Trial Multicenter Study
Predicting a diagnosis of acute coronary syndrome during telephone evaluation by an emergency dispatcher: the SCARE predictive scale.
Correctly identifying patients with acute coronary syndrome (ACS) on first contact is essential, yet emergency dispatchers currently lack a risk scale that can help predict an ACS diagnosis. Our main aim was to develop and validate such a risk scale. ⋯ The SCARE scale had good discrimination and calibration properties. The scale should be further validated in an external sample from a multicenter study before it is implemented by emergency dispatch centers.

Randomized Controlled Trial
Standard basic life support training of the European Resuscitation Council versus blended training: a randomized trial of a new teaching method.
To evaluate the immediate and 9-month results of blended versus standard training in basic life support and the use of an automatic external defibrillator (BLS/AED). ⋯ The blended training method led to better results on some skill items.
