Active learning significantly improved head computed tomography (CT) interpretation skills for emergency medicine residents compared to passive learning. This head CT curriculum enhanced diagnostic accuracy without additional time or resources.
Area of Science:
- Medical Education
- Radiology
- Emergency Medicine
Background:
- Head computed tomography (CT) interpretation is crucial for emergency physicians.
- Existing literature highlights poor concordance between emergency physicians and radiologists in head CT interpretation.
- Previous studies utilized passive learning, showing limited effectiveness in addressing this knowledge gap.
Purpose of the Study:
- To develop and evaluate an active learning curriculum for teaching head CT interpretation to emergency medicine residents.
- To compare the effectiveness of this active learning strategy against a traditional passive learning approach.
Main Methods:
- A prospective, randomized controlled study involving emergency medicine residents.
- Three educational sessions delivered via video conference over three months.
- Active learning cohort (ALC) used an interactive web-based system (Pascbin) for head CT cases; passive learning cohort (PLC) watched instructional videos of the same cases.
- Pre- and post-intervention tests were administered and analyzed using t-tests.
Main Results:
- The active learning cohort showed a significant improvement in mean test scores from 43.8% to 59.0% (P <0.001).
- The passive learning cohort demonstrated minimal improvement, with mean scores changing from 41.7% to 45.3% (P = 0.29).
- Post-test scores between the ALC and PLC showed a statistically significant difference (P = 0.009) with a large effect size (Cohen's d = 1.34).
Conclusions:
- The active learning head CT curriculum using Pascbin yielded superior learning outcomes compared to passive learning.
- This active learning intervention is effective, learner-centric, and requires no additional time or resources.
- It presents a more effective method for integrating radiology curricula into emergency medicine residency programs.
