Summary
General surgery residents lack essential trauma vascular skills due to limited exposure. The Open Surgical Simulation System (OS3) effectively improves resident confidence and competence in critical vascular procedures.
Area of Science:
- Surgical Education
- Trauma Surgery
- Vascular Surgery
Background:
- Endovascular techniques have reduced general surgery residents' exposure to essential trauma vascular procedures.
- This leads to a preparedness gap in managing basic vascular emergencies among new graduates.
- The Open Surgical Simulation System (OS3) offers high-fidelity simulation for hands-on skill acquisition.
Purpose of the Study:
- To evaluate the impact of a new OS3 surgical skills curriculum on residents' self-assessed knowledge, technical skills, and confidence.
- To analyze factors influencing skill self-assessments and course utility.
Main Methods:
- Pre- and post-course surveys using 5-point Likert scales assessed knowledge, skills, and confidence.
- Procedures included resuscitative thoracotomy, laparotomy, splenectomy, liver/small bowel management, and retroperitoneal exploration.
- Linear regression modeled determinants of self-assessments, challenges, and utility.
Main Results:
- 183 trainees completed the simulation; higher postgraduate year correlated with increased self-assessed knowledge, skills, and experience.
- Vascular shunt insertion, aortic crossclamp, and anastomosis were consistently challenging.
- OS3 simulation significantly boosted confidence in multiple trauma procedures (P < 0.02).
Conclusions:
- Nearly half of general surgery trainees report difficulty with essential trauma vascular procedures like shunting and aortic crossclamping.
- The OS3 provides consistent, reproducible training to address this confidence gap in vascular skills.
