Identifying the optimal thoracentesis training strategy: a randomized non-inferiority study.

Area of Science:

• Medical Education
• Clinical Skills Training
• Procedural Simulation

Background:

• Thoracentesis is a common procedure with unclear optimal training methods.
• Effective training is crucial for patient safety and procedural success.

Purpose of the Study:

• To compare a novel e-learning and simulation-based spaced learning program against traditional instructor-led massed training for thoracentesis.
• To assess non-inferiority in initial skill acquisition and superiority in skill retention.

Main Methods:

• Multicenter randomized non-inferiority study involving emergency physicians.
• Intervention group: e-learning plus spaced simulation sessions.
• Control group: single instructor-led simulation course.
• Outcomes assessed: skill acquisition at two weeks and retention at three months by blinded assessors.

Main Results:

• Sixty-three physicians were randomized.
• Initial skill passing rates at two weeks were comparable (66% intervention vs. 65% control).
• Skill retention at three months was significantly higher in the intervention group (92%) versus the control group (73%).

Conclusions:

• The novel spaced learning approach for thoracentesis training resulted in comparable initial skill acquisition.
• While underpowered for non-inferiority, the study suggests comparable initial learning.
• Self-directed spaced learning significantly improved long-term skill retention compared to traditional massed training.
