Brief Summary

Purpose: This study is designed to:

1. 1.Implement a website hosting perceptual learning modules (PLMs)
2. 2.Implement and assess a PLM designed to improve the capacity of fourth-year medical students and first-year residents (novices) to locate the brachial plexus (BP) at the level of the interscalene groove on surface ultrasound images.

Conditions

Medical Education

Outcome Measures

Primary Outcomes (1)

• Difference in correct locations of the BP between the pretest and the immediate post-test, for the Control group vs the PLM group.

  The BP for a case will be considered correctly located if the participant has placed a pointer inside a predefined "target zone", determined as representing the BP by three independent regional anesthesia experts.

  At baseline (pretest) and on the immediate post-test

Secondary Outcomes (4)

• Difference in the average distance of BP location

  At baseline (pretest) and on the immediate post-test

• Difference in correct locations of the BP

  At baseline (pretest) and on the delayed test at 6 months

• Average response times during the various tests

  At baseline (pretest), on an immediate post-test, and on the delayed test at 6 months

• For the PLM group only, the evolution of the participants' accuracy during the PLM

  During the PLM, at the end of the first on-line session

Study Arms (2)

Control (no PLM)

EXPERIMENTAL

Control: Pre, post, delayed test Participants will not do the PLM, but will perform a pretest, a posttest and a delayed test at 6 months

Other: Control (no PLM)

Experimental (PLM)

EXPERIMENTAL

Experimental: PLM group (pre, post, delayed test, PLM) Participants will do a pretest, the PLM, a posttest and a delayed test at 6 months

Other: PLM

Interventions

Control (no PLM) OTHER

Pre, post, delayed test Participants will perform a pretest, a posttest and a delayed test at 6 months.

Control (no PLM)

PLM OTHER

PLM Participants will take the PLM on the location of the brachial plexus at the level of the interscalene groove on surface ultrasound images. They will also take a pretest, a post-test and a delayed test at 6 months. Pre, post, delayed test Participants will perform a pretest, a posttest and a delayed test at 6 months.

Experimental (PLM)
