Firefighters as first-responders in out-of-hospital cardiac arrest - A retrospective study of a time-gain selective dispatch system in the Skåne Region, Sweden.

Aim: To analyze the impact of a time-gain selective, first-responder dispatch system on the presence of a shockable initial rhythm (SIR), return of spontaneous circulation (ROSC) and 30-day survival after out-of-hospital cardiac arrest (OHCA).

Method: A retrospective observational study comprising OHCA registry data and dispatch data in the Skåne Region, Sweden (2010-2018). Data were categorized according to dispatch procedures, two ambulances (AMB-only) versus two ambulances and firefighter first-responders (DUAL-dispatch), based on the dispatcher's estimation of a time-gain.

Emergency medical dispatchers' experiences of managing emergency calls: a qualitative interview study.

Objectives: To explore the emergency medical dispatchers (EMDs) experiences of managing emergency medical calls.

Design: A qualitative interview study with an inductive approach. EMDs were interviewed individually using a semistructured interview guide.

A registry-based observational study comparing emergency calls assessed by emergency medical dispatchers with and without support by registered nurses.

Background: The requirement concerning formal education for emergency medical dispatcher (EMD) is debated and varies, both nationally and internationally. There are few studies on the outcomes of emergency medical dispatching in relation to professional background. This study aimed to compare calls handled by an EMD with and without support by a registered nurse (RN), with respect to priority level, accuracy, and medical condition.

A comparison of two emergency medical dispatch protocols with respect to accuracy.

Background: Emergency medical dispatching should be as accurate as possible in order to ensure patient safety and optimize the use of ambulance resources. This study aimed to compare the accuracy, measured as priority level, between two Swedish dispatch protocols - the three-graded priority protocol Medical Index and a newly developed prototype, the four-graded priority protocol, RETTS-A.

Methods: A simulation study was carried out at the Emergency Medical Communication Centre (EMCC) in Stockholm, Sweden, between October and March 2016.

Correction of hypothermic and dilutional coagulopathy with concentrates of fibrinogen and factor XIII: an in vitro study with ROTEM.

Background: Fibrinogen concentrate treatment can improve coagulation during massive traumatic bleeding. The aim of this in vitro study was to determine whether fibrinogen concentrate, or a combination of factor XIII and fibrinogen concentrates, could reverse a haemodilution-induced coagulopathy during hypothermia.

Methods: Citrated venous blood from 10 healthy volunteers was diluted in vitro by 33% with 130/0.
