Study summary

This study aims to evaluate the average time taken by the Medical Regulation Assistants (MRA) to detect a cardiac arrest during the call to the EMS as well as the factors influencing this delay.

Its main objective is to evaluate the delay, in seconds, between the call being picked up and the recognition of a cardiac arrest by the medical regulation assistant at the EMS 95

Read the detailed description

In France, the incidence of cardiac arrest in adults is approximately 40,000 per year. It is a major cause of mortality with an average survival rate of 8%, as well as morbidity, particularly neurological morbidity for surviving patients. The majority of cardiac arrests occur at In France, the incidence of cardiac arrest in adults is approximately 40,000 per year. It is a major cause of mortality with an average survival rate of 8%, as well as morbidity, particularly neurological morbidity for surviving patients. The majority of cardiac arrests occur at home, in the presence of a witness.

In the event of a cardiac arrest, every minute counts. Studies have shown that the time between the patient's collapse and the start of ECM (External Cardiac Massage) is directly correlated to the survival rate after a cardiac arrest.

According to other studies, a maximum delay of 90 seconds between the call to the EMS and the recognition of the cardiac arrest would be the most optimal for the patient, but is it reached at the EMS 95? This study aims at evaluating the average time taken by the Assistants of Medical Regulation (ARM) to detect a cardiac arrest during the call to the EMS as well as the factors influencing this delay.

Its main objective is to evaluate the delay, in seconds, between the call pick-up and the recognition of a cardiac arrest by the medical regulation assistant at the EMS 95. This evaluation will be made in particular by determining the elements of language highlighting the cardiac arrest, those which lengthen the time of detection of the arrest and the delay of starting a procedure by the ARM. The study will be conducted within the EMS and will include a review of the current state of knowledge and experience of the MRAs. This study will be carried out within the EMS 95.

Interventions

  • OtherTime elapsed between the taking in charge of the call and the recognition of a cardiac arrest by the MRA

    Prospective study within the EMS 95, to evaluate if the maximum delay of 90 seconds between the call to the EMS and the recognition of the cardiac arrest is reached.

What researchers measure

Primary outcomes

  1. Evaluation, of the time elapsed (seconds) between the taking in charge of the call and the recognition of a cardiac arrest by the medical regulation assistant (ARM) of the EMS 95.

    Measure of the time in seconds between picking up the phone and the recognition of the cardiac arrest by the medical regulation assistant

    Time frame: At the end of the study, an average of 5 month

Secondary outcomes

  1. Identify language that highlights cardiac arrest

    Collection of the initial reason for appeal and everything said by the witness that may point to cardiac arrest

    Time frame: At the end of the study, an average of 5 month

  2. Identify language that increases the time to detect cardiac arrest

    Collection of everything said by the witness increasing the detection of the cardiac arrest

    Time frame: At the end of the study, an average of 5 month

  3. Evaluation of the time required for the MRA to initiate a procedure (AED search: External Automated Defibrillator or initiation of external cardiac massage assistance)

    Collection of time (seconds) between : * the MRA taking the call and requesting an AED search * the MRA taking the call and the start of external cardiac massage

    Time frame: At the end of the study, an average of 5 month

  4. Identification of factors that may influence the time to recognition of cardiac arrest (MRA experience, tone of the call)

    Collection of call tone (witness anxiety level) and MRA experience in years

    Time frame: At the end of the study, an average of 5 month
