Topic 10: Patient safety and invasive procedures Why patient safety is relevant to Although the principles described in this topic are surgery and invasive procedures 1 important for both surgical and invasive There is now plenty of evidence to show that procedures, most of the evidence in the literature patients who undergo a surgical or an invasive relates to surgical care. procedure are at increased risk of suffering an adverse event [1-3]. This is not because the Learning outcomes: knowledge and surgeons and proceduralists are careless or performance incompetent, rather it is because we now know about the many opportunities for things to go What does a student need to know wrong because of the many steps involved in (knowledge requirements): 3 surgical procedures.

One of the biggest problems in the operating The complexity of the surgical environment is a environment is miscommunication. major factor underpinning communication errors Miscommunication has been responsible for the and they occur at all levels.

In addition to high workloads, the peri-operative environment is characterized by staff with varying levels of experience and abilities. This combination of factors can seriously impact on the team’s ability to communicate accurately and timely. Communication problems occur at all stages—but particularly when patients are transferred from one phase of care to another. The extent of adverse surgical events involving wrong site surgery [3] led The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) [4] to include wrong site surgery in its national database of “sentinel events”. Many countries now collect data about wrong 218 Topic 10: Patient safety and invasive procedures Table 17.
