Clinical Simulation as a Learning Tool in Medical Students

The hypothesis of our work is that with the simulation techniques applied in the Medical School of the Autonomous University of Barcelona (UAB), students accelerate the learning curve of clinical skills, acquire transversal skills in medicine, and obtain a higher quality learning.

Learning through simulation lies in the recreation of a clinical event, skills or techniques in the most reliable way in order to ensure a much more active experiential learning method than the traditional one built through theoretical classes.

Simulation provides the possibility of scheduling the acquisition of knowledge and skills in a safe environment, in which mistakes have no consequences, at a time and place.

The true learning of the student is significant when there is a reflection and assimilation of what he has learned.

At the Medicine School of Autonomous University of Barcelona (UAB), simulation has begun to be applied as a learning method at different times during the academic year.

The hypothesis of our work is that with the simulation techniques applied in the Medical School of the UAB, students accelerate the learning curve of clinical skills, acquire transversal skills in medicine, and obtain a higher quality learning.

The investigators have designed a prospective and descriptive study, which includes simulation analysis in 3rd year medicine students at the UAB during the academic years 2020/2021 and 2021/2022.

The main objective is to know the effectiveness of simulation in 3rd year medical students, through the objective evaluation of clinical and transversal competences with Mini Clinical Evaluation Exercise (Mini-CEX)

The secondary objectives are:

* To know the effect of clinical care practice in 3rd year medical students
* To compare the effect of simulation with that of clinical practice
* Qualitative analysis of the simulation by analyzing its objectives
* Contrast the evaluation of the objectives between student who did the simulation, observer students and teacher.
* Contrast the evaluation of the objectives between the different cases of each session
* Analysis of emotional interference in the evaluation of objectives
* To evaluate the quality of the clinical simulation

The study consists of analyzing the basic skills of medical students through a Mini Clinical Evaluation Exercise (Mini-CEX), which is carried out in three moments of the academic year:

* At the beginning, where the students have not had any previous experience with clinical practices or simulation.
* In the middle of the course, where there are two groups of students, one that has only done clinical practice and the other that has only done simulation. So an evaluation with Mini-CEX is carried out having performed only one of the two interventions.
* At the end of the course, where all the students have carried out clinical practices and simulation.

In each simulation session, 5 clinical cases are carried out, where the acquisition of the objectives of the simulation session and the emotional state of the student who is performing the simulation in the practical scenario are evaluated.

This evaluation is carried out by means of a questionnaire that is filled out for each of the cases, specifying who fills it out: the student who has carried out the simulation, the observer students or the teacher.

At the end of the simulation period, a satisfaction questionnaire is collected and answered by all the participants to assess the quality of the simulation classes.

Statistical analysis:

Mini-CEX can be evaluated using a scale from 0 to 10 in different domains. The domains are: history, physical examination, professionalism, clinical judgment, communication skills, and organization and efficiency. There is a summary domain that is the examiner's global assessment. This scale can be easily measured using a visual analog scale (VAS), as well as a 10-point Likert scale. To facilitate the power and ease of statistical calculations, the investigators will use the VAS scale as the measurement element.

There is also a categorical option in the Mini-CEX evaluation where the exam can be unsatisfactory, satisfactory or superior.

The objectives of the simulation can be evaluated using a VAS scale from 0 to 10 in different domains and a categorical option between objective achieved, partially achieved and not achieved. The domains are: history, physical examination, doctor-patient relationship and clinical judgment.

The satisfaction questionnaire can be evaluated using a scale from 0 to 5 in different questions.

Quantitative variables will be described as meas and 95% confidence interval. Qualitative variables will be described as percentages and 95% confidence interval.

Comparisons between different means will be made using t student. Comparisons between different percentages will be made using chi squared. Comparisons between different categorical variables will be made using Mantel-Haenszel test. In all cases, the investigators will use an alfa value of 0.05.

To calculate the number of students needed to calculate two means (VAS values between 0 and 10), the investigators assume a standard deviation in both means of 2 with a minimum magnitude of the effect to be detected equal to 1, an alpha error of 0.05 and a beta error of 0.05. from 0.2; the number needed for a bilateral contrast test is 63.
