Improving patient safety in medicine: Is the model of anaesthesia care enough?

Abstract

Avoiding iatrogenic adverse outcomes and providing safe care to patients is a priority in modern healthcare systems. Because anaesthetic practice is inherently risky, the specialty has developed a broad range of strategies to minimise human error and risk for patients. These are part of a hierarchical model developed by industrial safety experts to minimise risk. It is known as the safety hierarchy model. This review will describe the use of this model in anaesthesia and show why the specialty is often cited as a role model for patient safety improvement. It will also explore the extension of the model to other specialties and analyse its intrinsic limitations due to new challenges to patient safety: teamwork and communication issues. These will conclude the review.
