About

The purpose of this study is to investigate the quality of cardio-pulmonary resuscitation(CPR) delivered by EMS professionals and whether this quality can be improved by implementing real-time feedback during the event and an oral post-event debriefing procedure based on the actual event performance data.

Full description

The aim of this study is to investigate whether CPR quality can be improved by implementing real-time feedback and immediate oral structured post-event debriefing in out-of-hospital cardiac arrest (OHCA).

The objectives of this study is to assess the current quality of CPR delivered by emergency medical services (EMS) during OHCA events in the Capital Region of Denmark. Furthermore, to investigate if CPR quality can be improved by applying real-time feedback during OHCA resuscitation attempts and to investigate if structured oral post-event debriefing delivered immediately after a resuscitation attempt and based on data from the defibrillator can further improve CPR quality

The hypothesis of this study is that adding real-time and post event feedback can improve the compression rate, compression depth, overall CPR hands-on time (CPR fraction), and recoil with at least 15% in total for both interventions.

Using a prospective study design data is retrieved from the standard defibrillator (ZOLL X series) through ZOLL RescueNet® Case Review (software for post-event review, analysis, and debriefing) from ZOLL Medical Corporation, Massachusetts, United States of America.

The study consists of three consecutive phases. Phase one with no feedback / debriefing available for EMS. Phase two with real-time feedback during the event and phase three which adds post-event debriefing to real-time feedback. We expect to be able to include at least 500 cases in each phase.

Enrollment: 2,989 patients

Inclusion criteria

OHCA

Exclusion criteria

No use of EMS defibrillator attached to patient during resuscitation attempt Patients < 18 years of age OHCA without involvement of the physician manned vehicle Patients who are subject to mechanical CPR from the time of device attachment Traumatic OHCA

Trial design

2,989 participants in 3 patient groups

Baseline

Description:

No CPR feedback during CPR

Real-time feedback

Description:

Real-time feedback on chest compression depth, chest compression rate and recoil available to EMS while performing CPR. Feedback is delivered as visual text, numeric and graphical presentations on the defibrillator with audio tones for rate.

Treatment:

Other: Real time feedback

Post-event debriefing

Description:

Structured oral post-event debriefing based on objective performance data from the resuscitation attempt. The debriefing is conducted as hot/immediate self-directed debriefing session with a maximum length of 10 minutes.

Treatment:

Behavioral: Post-event debriefing

Other: Real time feedback
