Influence of Resident Training on Intra-operative Workflow

Study Overview
=================
Brief Summary
-----------------
Anaesthesia and surgery related time intervals of three standard operations are compared depending on whether residents or consultants are performing anaesthesia and surgery. Hypothesis: Perioperative workflow is influenced by state of education, time intervals reflecting anaesthesia as well as surgical performance increase due to resident training. Therefore, costs of perioperative care increase as well.
