Randomized Controlled Trial
Dispatcher-assisted BLS for lay bystanders: A pilot study comparing video streaming via smart glasses and telephone instructions.
To determine whether dispatcher assistance via smart glasses improves bystander basic life support (BLS) performance compared with standard telephone assistance in a simulated out-of-hospital cardiac arrest (OHCA) scenario. ⋯ Smart glasses could significantly improve dispatcher-assisted bystander performance in an OHCA event. Their potential in real-life situations should be evaluated.

Clinical Trial
NT-proBNP cut-off value for ruling out heart failure in atrial fibrillation patients - A prospective clinical study.
N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements can be used to rule out heart failure in patients with sinus rhythm. Atrial fibrillation often coexists with heart failure but affects NT-proBNP levels. This study aims to identify the optimal NT-proBNP cut-off value for ruling out heart failure among atrial fibrillation patients. ⋯ NT-proBNP can be used to rule out heart failure in atrial fibrillation patients with a high negative predictive value, but low specificity.

In an effort to improve sepsis outcomes the Centers for Medicare and Medicaid Services (CMS) established a time sensitive sepsis management bundle as a core quality measure that includes blood culture collection, serum lactate collection, initiation of intravenous fluid administration, and initiation of broad-spectrum antibiotics. Few studies examine the effects of a prehospital sepsis alert protocol on decreasing time to complete CMS sepsis core measures. ⋯ This study questions the effectiveness of prehospital sepsis alert protocols on decreasing time to complete CMS sepsis core measures. Future studies should address if these times can be impacted by having EMS providers independently administer antibiotics.

Influenza shares common symptoms with bacterial pneumonia, which may result in unnecessary antibiotic prescriptions in the emergency department (ED) when the diagnosis is unknown. Rapid influenza polymerase chain reaction (PCR) tests have reduced turnaround times compared to standard multiplex PCR respiratory panels allowing for earlier diagnosis, which may improve antimicrobial stewardship outcomes in the ED. This study aims to compare antibiotic and antiviral use before and after deployment of the rapid influenza PCR in the ED. ⋯ Implementation of a rapid influenza PCR in the ED reduced antibiotic use and optimized antiviral therapy for patients with influenza including those at higher risk of complications.

Here we present the case of a patient with right upper extremity and right lower extremity weakness of a three-day duration, which triggered a stroke evaluation. Ultimately, the diagnosis of spinal epidural lipomatosis (SEL) was made. Non-stroke diagnoses that present with stroke-like symptoms are referred to in the medical literature as stroke mimics. ⋯ The frequency of such presentations occurs in up to 30% of initially suspected stroke. This case illustrates that SEL can present as a stroke mimic. To our knowledge, this is the first description of a presentation in the medical literature of SEL as a stroke mimic.
