Background: Syncope is a common condition that may be prevented. There are non-pharmacological interventions that may be of benefit during the acute episode preceding syncope (presyncope), including physical counter-pressure maneuvers (PCM) or change of body position. We performed a systematic review of interventions that may be applied during presyncope as an immediate, first aid tactic. ⋯ No adverse events were reported. Conclusion: While there is a minimal amount of evidence available and the findings were mixed, PCM may provide benefit for prevention of syncope during acute episodes of presyncope and may be tried in the first aid setting. No evidence was found for other non-pharmacologic interventions or for the use of PCM in children.

We present the case of a 30-year-old man with a subcutaneous implantable cardioverter defibrillator (S-ICD) who suffered sudden out-of-hospital cardiac arrest. During resuscitation, the patient received inappropriate shocks due to oversensing by the S-ICD of chest compression induced artifact. ⋯ Placement of a magnet over the S-ICD generator failed to inhibit the delivery of S-ICD shocks. Information regarding inappropriate S-ICD shocks may be useful during resuscitation of patients with sudden cardiac arrest.

Observational Study
How Well Do EMS Providers Predict Intracranial Hemorrhage in Head-Injured Older Adults?
Objective: To evaluate the accuracy of emergency medical services (EMS) provider judgment for traumatic intracranial hemorrhage (tICH) in older patients following head trauma in the field. We also compared EMS provider judgment with other sets of field triage criteria. Methods: This was a prospective observational cohort study conducted with five EMS agencies and 11 hospitals in Northern California. ⋯ Actual transport was comparable to EMS provider judgment (sensitivity 71.1%, 95% CI 60.0-80.0%; specificity 35.3%, 95% CI 31.6-38.3%). Conclusions: As EMS provider judgment for tICH increased, the incidence for tICH also increased. EMS provider judgment, using a threshold of 1% or higher suspicion for tICH, was more accurate than current field triage criteria, with and without additional risk factors included.

Background: To evaluate a new strategy for identifying sepsis in Emergency Department (ED) patients that combines administrative diagnosis codes with clinical information from the point of first contact. Methods: This study linked clinical data from adult patients transported by a provincial Emergency Medical Services (EMS) system to ED and inpatient administrative databases. Sepsis cases were identified by searching ED databases for diagnosis codes consistent with infection and organ dysfunction. ⋯ The novel strategy requiring the presence of an infection code and either an organ dysfunction code or 2 or more SOFA points from EMS clinical information identified 1,379 more ED patients as having sepsis than the inpatient algorithm. These patients had high mortality supporting construct validity. Conclusions: Incorporation of a broader range of diagnostic codes and linking to an electronic database to obtain initial clinical information for the assessment of organ dysfunction improves reliability, criterion, and construct validity for identifying sepsis in ED patients.

On March 13, 2019 the EMS Examination Committee of the American Board of Emergency Medicine (ABEM) approved modifications to the Core Content of EMS Medicine. The Core Content is used to define the subspecialty of EMS Medicine, provides the basis for questions to be used during written examinations, and leads to development of a certification examination blueprint. The Core Content defines the universe of knowledge for the treatment of prehospital patients that is necessary to practice EMS Medicine. It informs fellowship directors and candidates for certification of the full range of content that might appear on certification examinations.
