Introduction:
Education for residents in surgery varies not only throughout the world, but also throughout Europe. Our clinic is well connected to Maastricht University Medical in Centre in the Netherlands (European Surgical Centre Aachen Maastricht). On the other hand, there are clear differences in resident programs. In the Netherlands, a structured feedback according to the OSATS concept (Objective Structured Assessment of Technical Skills) is mandatory after every operation performed by residents. The aim of the present study was to transfer the OSATS concept from Maastricht to Aachen and to evaluate the feasibility and benefits of this concept for surgical education.
Material And Methods:
The OSATS concept was implemented for 3 months in our clinic within a prospective clinical trial. Seven out of 10 residents that were working in our clinic at that time participated in the study (70%). Half of these were assigned to structured written feedback after every autonomously performed operation. Additionally, all participants performed structured written proper feedback according to the OSATS concept. The primary endpoint was the feasibility of the OSATS concept in our clinic; secondary endpoints were the benefits for the residents and the differences between external and self-evaluation.
Results:
The OSATS-concept was easily implemented in our clinic and met wide acceptance. Evaluation was performed after a mean of 70% of operations. External evaluation was regarded as more beneficial for residents than self-evaluation. Structured written evaluation according to the OSATS concept was not time-consuming (< 3 minutes) and most residents (86%) supported permanent implementation of the OSATS concept in our clinic.
Conclusion:
The OSATS concept is a suitable approach to provide structured feedback to residents in continuous education. It can easily be implemented in resident education in Germany. Structured, written feedback by senior physicians is perceived as beneficial by residents.
