研究概览
简要总结
The goal of this observational study is to explore the optimisation and integration of a drone-delivered Automated External Defibrillator (AED) system into the pre-hospital response to out-of-hospital cardiac arrest. The study is being conducted by the University of Warwick and Welsh Ambulance Service National Health Service Trust (both in the UK)
There are two separate packages of work. In work package 1 the investigators will interview people who have been involved in emergency (999) calls for cardiac arrest, asking them about their experiences with the call-handler and how they feel they might have responded if they had received an AED that had been delivered by a flying drone.
In work package 2 the investigators will conduct simulated cardiac arrests. The participants in the study will make an emergency (999) call to a trained call-handler and, once the cardiac arrest is identified during the call, a drone will be activated from a distant location and fly up to 2km to the test site and deliver an AED. The investigators will record how long it takes to retrieve and attach the AED, and ask the participants for their views about the interaction with the call-handler, AED and drone.
详细描述
Background and study aims
Only 10% people survive after having a cardiac arrest in the community. Delivering an electric shock to the heart using a defibrillator greatly improves someone's chance of surviving.
Automated External Defibrillators (AEDs) are a type of defibrillator that may be found in public places. You can attach an AED to someone who is having a cardiac arrest. The AED may give them an electric shock and help their heart beat normally again. They are safe for members of the public to use, even if they are not trained to use them.
However, if a person is helping someone who has had a cardiac arrest it may be very difficult to find a nearby AED soon enough to make a real difference. There may be better ways to deliver AEDs quickly to more people who need them. In Sweden, ambulance services use flying drones to deliver AEDs to people after cardiac arrest. Nobody has yet demonstrated how the investigators will do this in the UK.
This study aims to explore the optimisation and integration of a drone-delivered AED system into the pre-hospital response to out-of-hospital cardiac arrest, as a necessary pre-requisite to real-life flight operations.
