NCT03245567

Brief Summary

This study is designed to:

  1. 1.Implement a Web platform intended to host perceptual learning modules (PLMs)
  2. 2.Implement and assess a PLM designed to improve the capacity of first-year residents and fourth-year medical students to visually estimate the left ventricular ejection fraction (LVEF) with transesophageal echocardiography (TEE) images.

Outcome Measures

Primary Outcomes (1)

  • Change in accuracy of LVEF estimation in the Control group versus the PLM group

    For each case, the absolute difference between the participant and the experts' estimation of LVEF is calculated. Participant's accuracy is defined as the average of absolute differences for all cases in the test

    At baseline (pretest) and on the immediate posttest

Secondary Outcomes (3)

  • Change in accuracy of LVEF estimation in the Control group versus the PLM group

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

  • Change in the mean response time in seconds to the different tests in the Control group versus the PLM group

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

  • The evolution of the participants' accuracy in LVEF estimation during the PLM

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

Study Arms (2)

Pre, post, delayed test

EXPERIMENTAL

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

Other: Pre, post, delayed test

Interventions

PLMOTHER

Participants will take the PLM on the visual estimation of LVEF. They will also take a pretest, a post-test and a delayed test at 6 months.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Residents in their first year of training or fourth-year medical students having access to a computer with a high speed internet connection
  • Residents or medical students with no significant experience in echocardiography

You may not qualify if:

  • Smartphones and tablets will not be acceptable to perform the tests due to their smaller screens
  • Residents or medical students having significant experience with transthoracic or transesophageal echocardiography
