Exploration of a quality improvement process to standardised preoperative tests for a surgical procedure to reduce waste.

Background: Preoperative tests are done to determine a patient's fitness for anaesthesia and surgery.

Local Problem: Although routine tests before surgery in the absence of specific clinical indications are not recommended, we observed high volumes of routine preoperative tests were performed in our institution. We describe a process to implement a standardised preoperative investigational approach to reduce unnecessary testing before surgeries.
