In minimally invasive surgeries, endoscopes are used. Due to their cost, these are reusable and therefore must be thoroughly cleaned and sterilised to be suitable for the next surgery. To ensure they remain in suitable condition, systems are in place to measure and monitor the optical quality of endoscopes. In practice, however, staff often find it difficult to interpret the results, particularly when measurements fall into an ambiguous range. This can lead to uncertainty: can the endoscope still be used, or should it be replaced? Although the measurement process itself is relatively straightforward, interpreting the results requires a certain level of expertise among central sterile department (CSD) personnel. This process typically involves collaboration between CSD staff, operating room teams, and surgeons.
