Simulator training improves ultrasound scanning performance on patients: a randomized controlled trial

Area of Science:

• Medical Education
• Radiology
• Ultrasound Technology

Background:

• Simulation-based mastery training shows potential for improving clinical skills.
• This study investigates its impact on abdominal diagnostic ultrasound proficiency in radiology residents.

Purpose of the Study:

• To evaluate the effectiveness of simulation-based mastery training on radiology residents' performance in abdominal diagnostic ultrasound.
• To compare the learning curves of residents undergoing simulation training versus standard clinical training.

Main Methods:

• A multicenter randomized controlled trial involving 20 radiology residents.
• Participants were randomized to either simulation-based training with mastery testing or standard clinical training.
• Performance was assessed using the Objective Structured Assessment of Ultrasound Skills (OSAUS) and analyzed with non-linear regression.

Main Results:

• The simulation group demonstrated significantly higher performance scores in the initial 29 scans compared to the control group.
• Both groups achieved similar performance levels, with simulation trainees reaching them after fewer scans.
• Simulation participants completed 2-7 sessions, totaling 6-17 hours of training.

Conclusions:

• Simulation-based mastery learning significantly improves diagnostic ultrasound scanning performance in radiology residents.
• This training method can mitigate the impact of the early learning curve on patient care.
