About this trial
Appropriate management of cardiac arrest (immediately and technically well performed) is a priority that must be taught to all citizens and future healthcare personnel, including future physicians. In this medical school, 2nd year medical students receive a 8 hour training session on basic life support (BLS) and management of cardiac arrest is taught into 5 successive parts, with learning and cumulative repetition of the steps: detection of unconsciousness, call for help, absence of breathing, cardiac massage and defibrillation.
During the many sessions previously carried out by our team, it often appeared that students, when evaluating breathing forget the 1st part related to airway and breathing, i.e. relieving airway obstruction. Yet it has been shown that opening the airway and early removal of a foreign body are associated with improved neurological survival. Importantly, mouth-to-mouth is not included in the learning session and compression-only is advocated.
The purpose of the present study is to evaluate if the use of an observation tool, with items centered on airway obstruction, can improve learning of this step, as shown in some previous trials.
This will be a trial performed in medical students in which training days will be randomized to include or not the use of an observation tool modified to emphasize the procedural parts that are aimed at relieving airway obstruction.
At the end of each day, students will be video-recorded while playing a short BLS scenario and airway obstruction-relieving skills will be compared.

Trial outcomes
Primary outcomes
1
checklist describing performance of each dyad while performing BLS
comparison of airway management skills, i.e. measured by external evaluation from the six items of the checklist related to this task between the OT + group and the OT- group among the checklist of items describing in detail the actions performed during BLS maximum score of 6/6 higher scores mean a better outcome Each item is scored 1 point
Time frame
From enrollment to the end of treatment at six monthsSecondary outcomes
1
checklist of the whole observer tool on task performance (20 items)
Global performance of each dyad measured by external evaluation while performing BLS by comparing overall management skills, i.e. the 20 items between the OT + group and the OT- group maximum score of 20/20 higher scores mean a better outcome Each item is scored 1 point
Time frame
From enrollment to the end of treatment at six months2
Separate analysis of each of the 5 BLS sequences
comparison of the performance of the two groups for each step of the checklist : detection of unconsciousness (4 items), call for help (4 items), absence of breathing (7 items), cardiac massage (5 items) and defibrillation (5 items). Each of the 5 steps is measured by external evaluation Each item is scored 1 point Higher scores indicate better performance
Time frame
From enrollment to the end of treatment at six months3
questionnaire satisfaction (post session)
Satisfaction will be assessed by a Likert scale (0 to 10) (Kirkpatrick level 1
Time frame
From enrollment to the end of treatment at six months4
Questionnaire: educational value of an observer tool
Perception about the educational value of an observer tool by a Likert scale (0 to 10) (Kirkpatrick level 1)
