Teaching Simple Skin Sutures to Medical Students

Study Overview
=================
Brief Summary
-----------------
Learning the simple skin suture is part of the surgical basics required for all medical students, including future general practitioners. However, there is no data in the educational literature to help choose the best learning technique. Several teams have offered video learning showing the correct technique. Level n+1 peer learning was also proposed, without and with supervision by an expert. The investigators propose to carry out a prospective study comparing the quality of sutures and knowledge according to the chosen learning method.

Detailed Description
-----------------
Send to medical student a teaching package two weeks before simulation session to practice skin suture. There are 4 teaching packages related to 4 interventional groups The skin suture performed by medical students are recorded on video. 1 video per medical student. The skin sutures recorded in these video are rated by two blinded expert with evaluation grid. After the simulation session, the students complete knowledge, self-confidence, satisfaction and mental load questionnaires

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| quality of skin suture | Quality of suture on anonymized video recording during the assessment day, rated by the blinded expert using an evaluation grid evaluation grid is made up of 14 items from the litterature the minimum value is: 0 (worse outcome) and maximum value is: 15 points (better outcome) | 15 days after simulation session | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| knowledge of student | 8 multiple choice questions (5 items per MCQ); the minimum value is: 0 (worse outcome) and maximum value is: 8 points (better outcome) | 15 days after simulation session | 
| self-confidence of student | self evaluation with a Likert scale (5points); point 0 corresponds to no confidence; point 5 corresponds to total confidence | 15 days after simulation session | 
| mental load of student | self evaluation with a Likert scale (9points); point 0 corresponds to very low; point 9 corresponds to very high | 15 days after simulation session |
