Insights
Junior cardiac surgeons can achieve proficiency in coronary artery anastomosis with training, matching senior surgeons' skill levels. Early career training is effective for addressing the cardiac surgeon shortage.
Area of Science:
- Cardiovascular Surgery
- Surgical Education
- Medical Training
Background:
- Global shortage of cardiac surgeons impacts patient care, particularly for coronary artery bypass grafting.
- China faces significant challenges in meeting the demand for cardiac surgical procedures.
Purpose of the Study:
- To evaluate the suitability of early-career cardiac surgeons for coronary artery anastomosis training.
- To compare the learning curves and outcomes of junior versus senior surgeons in coronary artery anastomosis.
Main Methods:
- 12 cardiac surgeons with no prior experience were divided into junior and senior groups.
- Training in coronary artery anastomosis was provided, followed by in vivo and in vitro assessments.
- Surgical performance was evaluated using standardized rating scores.
Main Results:
- Post-training scores significantly improved across all participants (overall, junior, and senior).
- No significant differences were found in pre-training or post-training scores between junior and senior groups.
- Junior surgeons attained comparable outcomes to senior surgeons after undergoing the same training.
Conclusions:
- Seniority does not confer an advantage in coronary artery anastomosis without prior training.
- Early-career cardiac surgeons are capable of achieving proficiency in coronary artery anastomosis through structured training.
- Training programs can effectively enhance the skills of junior surgeons, mitigating the impact of surgeon shortages.
Objective:
Many countries are facing a shortage of cardiac surgeons, who are crucial in meeting the demands of growing number of patients in need of coronary artery bypass grafting. This situation poses a serious challenge, especially in China. The purpose of this study is to determine whether cardiac surgeons are suitable for training in coronary artery anastomosis at an earlier stage in their career.
Methods:
We divided 12 cardiac surgeons with no prior experience in coronary artery anastomosis into senior and junior groups for training and assessment. All trainees received training in coronary artery anastomosis for a defined period. We performed in vivo and in vitro examinations before and after training, respectively. Additionally, we assessed individual surgical performance of surgeons by using performance rating scores, including different aspects of surgical skills rated on a five-point scale.
Results:
The post-training scores (overall, junior, senior) were significantly higher than the pre-training scores (overall, junior, and senior). We observed no differences in pre-training and post-training scores between the junior and senior groups.
Conclusion:
Senior surgeons did not had any significant advantages over junior surgeons with respect to coronary artery anastomosis in the absence of training. Junior surgeons achieved the same results as the senior surgeons after training.
