Cardiac arrest is one of the leading causes of death in the United States and is treated by cardiopulmonary resuscitation (CPR). CPR involves both chest compressions and positive pressure ventilations when given by medical providers. Mechanical chest compression devices automate chest compressions and are beginning to be adopted by emergency medical services with the intent of providing high-quality, consistent chest compressions that are not limited by human providers who can become fatigued. Biosignals acquired from cardiac arrest patients have been characterized in their ability to track the effect of CPR on the patient. The authors investigated the feasibility and appropriate response of a biosignal-guided mechanical chest compression device in a swine model of cardiac arrest. ⋯ In this proof-of-concept study, a signal-guided chest compression device was demonstrated to be capable of responding to biosignal input and delivering chest compressions with a broad range of rates and depths.

The Broselow tape is a length-based tool used for the rapid estimation of pediatric weight and was developed to reduce dosage-related errors during emergencies. This study seeks to assess the accuracy of the Broselow tape and age-based formulas in predicting weights of South Sudanese children of varying nutritional status. ⋯ The Broselow tape and age-based formulas selected for comparison were all markedly inaccurate in both the nonmalnourished and the malnourished populations studied, worsening with increasing malnourishment. Additional studies should explore appropriate methods of weight and dosage estimation for populations of low- and low-to-middle-income countries and regions with a high prevalence of malnutrition.

Review Meta Analysis
Effectiveness of Educational Interventions to Increase Primary Care Follow-up for Adults Seen in the Emergency Department for Acute Asthma: A Systematic Review and Meta-analysis.
Patients with asthma commonly present to emergency departments (ED) with exacerbations. Asthma guidelines recommend close follow-up with a primary care provider (PCP) after ED discharge; however, this linkage is often delayed or absent. The objective of this study was to assess whether ED-directed educational interventions improve office follow-up with PCPs after ED discharge for acute asthma. ⋯ ED-directed educational interventions targeting either patients or providers increase the chance of having office follow-up visits with PCPs after asthma exacerbations. Their impact on health-related outcomes (e.g., relapse and admissions) remains unclear.

Randomized Controlled Trial
Adherence to an Accelerated Diagnostic Protocol for Chest Pain: Secondary Analysis of the HEART Pathway Randomized Trial.
Accelerated diagnostic protocols (ADPs), such as the HEART Pathway, are gaining popularity in emergency departments (EDs) as tools used to risk stratify patients with acute chest pain. However, provider nonadherence may threaten the safety and effectiveness of ADPs. The objective of this study was to determine the frequency and impact of ADP nonadherence. ⋯ Real-time use of the HEART Pathway resulted in a nonadherence rate of 20%, mostly due to overtesting. None of these patients had MACE within 30 days. Nonadherence decreased the discharge rate, attenuating the HEART Pathway's impact on health care use.

Observational Study
Intravenous Ondansetron and the QT Interval in Adult Emergency Department Patients: An Observational Study.
Ondansetron is known to cause QT interval prolongation, but this effect and clinical significance has not been prospectively studied in adult emergency department (ED) patients. The primary objective was to determine the mean maximal corrected QT interval (QTc) prolongation after intravenous (IV) administration of 4 mg of ondansetron. The secondary objective was to report any serious adverse cardiac electrical events. ⋯ While QTc prolongation does occur in adult ED patients receiving IV ondansetron, the clinical impact is questionable.
