Brief Summary

Time to defibrillation is the most important predictor of survival in cardiac arrest. Recent studies have shown that unmanned drones can deliver AEDs to the site of real life out-of hospital cardiac arrest (OHCA) before ambulance arrival. Although an AED is available in the close vicinity, they are seldom used. The overall aim of this study is to provide an interventional bundle directed towards the dispatch centre and evaluate referral of callers to retrieve drone-delivered AEDs so that they may be attached in cases out-of-hospital cardiac arrest.

Outcome Measures

Primary Outcomes (1)

• Proportion (percent) of cases where a bystander attaches a drone-delivered AED to the OHCA- patients chest, prior the arrival of EMS.

  In all alerts to suspected OHCA where a drone took off and delivered an AED on the ground, all cases were a bystander attaches the drone delivered AED to the OHCA-patients chest as instructed in T-CPR protocol before ambulance arrival will be measured. In all alerts to suspected OHCA where a drone took off and delivered an AED on the ground, all cases were a bystander attaches the drone delivered AED to the OHCA-patients chest as instructed in T-CPR protocol before ambulance arrival will be measured. Percentages.

  Up to 12 months

Secondary Outcomes (2)

• Proportion (percent) of cases where a dispatcher verbally refers a bystander to retrieve a drone-delivered AED on the ground before EMS arrival in cases of OHCA

  Up to 12 months

• Proportion (percent) of cases where a bystander successfully retrieves a drone-delivered AED from the ground as instructed by the dispatcher.

  Up to 12 months

Study Arms (1)

Automated flying Drone carrying an Automated external defibrillator (AED)

EXPERIMENTAL

Totally six drone systems are setup to be deployed in suspected OHCA cases as a complement to EMS. This is a single-arm intervention evaluating referral of bystanders during 112-calls to retrieve drone delivered AEDs in suspected OHCA.

Device: Automated flying Drone carrying an Automated external defibrillator (AED)

Interventions

Automated flying Drone carrying an Automated external defibrillator (AED) DEVICE

Totally n=6 drones are equipped with automated external defibrillators (AEDs). These drones are deployed by the dispatch centre to cases of suspected out-of-hospital cardiac (OHCA) as a complement to standard care (ambulance/EMS) over up to 12 months Monday to Sunday 08:00-22:00. The bystander onsite receives instructions from the dispatcher to retrieve the AED outside the house when it has been delivered by the drone. The bystander attaches the AED to the patients chest to facilitate early defibrillation. An interventional package directed to the dispatchers is distributed and consists of an e-learning program, an AED -trainer placed at the dispatch center. Within the dispatcher decision tool - there is information how to inform the caller to retrieve the AED. The HEMS-coordinator reminds the dispatcher during the call on operational information. Monthly information to staff of project progress is provided.
