Critical errors in infrequently performed trauma procedures after training.

Area of Science:

• Surgical Education
• Trauma Surgery Performance
• Medical Error Analysis

Background:

• Critical errors in surgery significantly increase patient morbidity and mortality.
• A novel trauma readiness index was developed to assess critical errors in trauma procedures.
• The study hypothesized that pretraining assessment using this index could predict residents likely to make critical errors.

Purpose of the Study:

• To evaluate the effectiveness of a trauma readiness index in identifying surgical residents prone to critical errors.
• To compare resident performance with practicing surgeons and experts.
• To determine if the trauma readiness index can predict critical errors across different surgical experience levels.

Main Methods:

• A prospective study evaluated 40 residents on 4 trauma procedures using a standardized script on cadavers.
• Residents were assessed before and after Advanced Surgical Skills for Exposure in Trauma (ASSET) training, with a 14-month follow-up.
• Performance was compared to 34 practicing surgeons and 10 expert surgeons.

Main Results:

• Resident trauma readiness index scores improved significantly post-training and remained stable.
• Trained residents demonstrated fewer critical errors compared to practicing surgeons.
• A low trauma readiness index (<0.60 Youden Index) reliably predicted critical errors in all surgeon groups.

Conclusions:

• The trauma readiness index is a valuable tool for identifying surgeons, including residents, who are likely to commit critical errors.
• Low scores on the trauma readiness index indicate a need for remedial training.
• Expert surgeons exhibited superior error recovery compared to residents and practicing surgeons.
