Accuracy and Quality of Clinical Decision Rules for Syncope in the Emergency Department: A Systematic Review and Meta-analysis
By L Serrano, et al.
Editor’s Capsule Summary
- What is already known on this topic: Prediction rules have been proposed to assist in the identification of syncope patients at low risk for poor short-term outcomes.
- What question this study addressed: The authors performed a systematic review that included a meta-analysis of two syncope prediction rules for which multiple studies had been published.
- What this study adds to our knowledge: Performance of the rules was variable. Outcome rates in the low-risk groups ranged from 2% to 36% and from 5% to 13% with the San Francisco and the Osservatorio Epidemiologico sulla Sincope nel Lazio rules, respectively.
- How this is relevant to clinical practice: Clinicians should not rely solely on a prediction rule in deciding on the disposition of emergency department patients with syncope.
Improved Out-of-Hospital Cardiac Arrest Survival After the Sequential Implementation of 2005 AHA Guidelines for Compressions, Ventilations, and Induced Hypothermia: The Wake County Experience
By PR Hinchey, et al.
Editor’s Capsule Summary
- What is already known on this topic: The 2005 AHA Guidelines recommend chest compression before defibrillation for unwitnessed ventricular fibrillation/ventricular tachycardia and one shock versus three, and postresuscitation hypothermia induction, while deemphasizing ventilations.
- What question this study addressed: This 1,365-patient observational time-series measured survival-to-hospital-discharge in patients with ventricular fibrillation/ventricular tachycardia during a tiered implementation of the 2005 guidelines.
- What this study adds to our knowledge: In this urban/suburban EMS system, there was a doubling of survival between the pre- and postimplementation phases.
- How this is relevant to clinical practice: This paper provides support for the 2005 guidelines, but the findings should be confirmed in other systems and, ideally, with randomized trials.
