Advanced trauma life support versus Combat Trauma Life Support courses: a comparison of cognitive knowledge decline

Area of Science:

• Medical Education
• Trauma Care
• Knowledge Retention

Background:

• Physicians require continuous medical education to maintain proficiency in trauma care.
• Advanced Trauma Life Support (ATLS) and Combat Trauma Life Support (CTLS) are critical training programs for managing trauma patients.
• Understanding knowledge decay in these crucial areas is essential for patient safety.

Purpose of the Study:

• To compare the rate of cognitive knowledge decline between ATLS and CTLS course graduates.
• To identify if the type of trauma course influences long-term knowledge retention.
• To inform recommendations for refresher training strategies in trauma medicine.

Main Methods:

• A prospective study involving 211 graduates of ATLS and CTLS courses in Israel.
• Assessment of knowledge using multiple-choice questions administered 3 to 66 months post-course.
• Comparison of delayed test results with immediate post-course examination scores.
• Application of survival analysis to model and compare knowledge decline patterns.

Main Results:

• No statistically significant difference was observed in the rate of knowledge decline between ATLS and CTLS graduates.
• Cognitive knowledge retention showed a similar decay pattern for both trauma training modalities over the study period.
• Individual variations in knowledge retention were noted, but course type did not predict decline rate.

Conclusions:

• The type of initial trauma life support course (ATLS vs. CTLS) does not significantly impact the long-term rate of knowledge decline.
• Physicians' need for refresher training in trauma care is independent of the specific course they initially attended.
• Recommendations for continuing medical education should focus on timely refresher courses for all physicians involved in trauma care.
