The Lilypond: An integrated model of Safety II principles in the workplace. A quantum shift in patient safety thinking (13 April 2020)

Summary

The Lilypond is a new conceptual model to describe patient safety performance. It radically diverges from established patient safety models to develop the reality of complexity within the healthcare systems as well as incorporating Safety II principles.

There are two viewpoints of the Lilypond that provide insight into patient safety performance. From above, we are able to observe the organisational outcomes. This supersedes the widely used Safety Triangle and provides a more accurate conceptual model for understanding what outcomes are generated within healthcare. From a cross-sectional view, we are able to gain insights into how these outcomes come to manifest. This includes recognition of the complexity of our workplace, the impact of micro-interactions, effective leadership behaviours as well as patterns of behaviour that all provide learning. This replaces the simple, linear approach of The Swiss Cheese Model when analysing outcome causation. By applying the principles of Safety II and replacing outdated models for understanding patient safety performance, a more accurate, beneficial and respectful understanding of safety outcomes is possible.
