Using Expert Visual Search Strategy to Train Students to Read the Chest X-rayPhase 3NCT01883570
Improving Search Strategy for Identifying Urgent Conditions on the Chest X-ray
A Phase 3 study testing training in visual search strategy and access to a library of chest x-rays without search strategy in people with Using Expert Visual Search Strategy to Train Students to Read the Chest X-ray, run by Université de Montréal at 1 site in Canada.
Trial summary
Currently, teaching X-ray interpretation to medical students is not standardized, and is generally not very effective. Objective: The goal of our study is to evaluate whether directly teaching an expert search strategy for x-ray interpretation to 3d year medical students is effective. Read more about this study

Methods:
- An expert's visual search strategy was recorded using a gaze-tracking device. The search strategy was then reproduced using a dynamic cursor moving across the corresponding chest x-ray, and incorporated into a teaching program accessible via the internet.
- Participants are 3rd year medical students who will be randomized into two groups. The experimental group will have access to the teaching program as described. The control group will have access to the same x-rays but not the expert's search strategy.
- At the end of the study period the investigators will collect performance data (the participants' accuracy at reading a series of chest x-rays) and process data (using gaze-tracking to evaluate the participants' search strategies); the experimental and control groups will be compared.
Expected results:
The investigators expect the group trained in expert search strategy to show improved accuracy at reading chest x-rays, and an improvement in their visual search strategy

What is being measured
The primary outcome is the main question the study is designed to answer.
Improvement in medical student's visual search strategy at reading a chest x-ray
participants enrolled in the experimental group will be trained to learn the expert's search strategy for reading a chest x-ray. We hypothesize that by the end of the study period they will show an improved visual search strategy over students who were not trained in visual search but were taught through standard methods (interaction with clinician-educators during their clerkship rotations)
Measured: 2 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing training in visual search strategy and access to a library of chest x-rays without search strategy in people with Using Expert Visual Search Strategy to Train Students to Read the Chest X-ray, run by Université de Montréal at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 21 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Improvement in medical student's visual search strategy at reading a chest x-ray (time frame: 2 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jun 2013.
