Abstract:
This study aims to explore how often the operating list is changed on the day of surgery and the reasons why this may occur. The purpose was to analyse the wider potential impact that changing the list on the day of surgery may have on patient safety, patient satisfaction and theatre efficiency. Survey data was collected across a multi-specialty elective operating department. The findings demonstrated that a significant change in operating lists occurred in 37.3% of sessions, for a variety of potentially avoidable reasons. We concluded that improved organisation and communication before the planned session could reduce the occurrence of changes, thereby increasing patient safety, theatre efficiency and potentially reducing incidents.

Work Done During Volume Change
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

To understand this phenomenon, consider the elementary reaction:
