Hot cheese: a processed Swiss cheese model.

Area of Science:

• Systems engineering
• Patient safety
• Risk management

Background:

• The Swiss cheese model is a widely used but criticized metaphor for accident causation.
• Its simplicity and static representation of defenses limit its utility in complex systems.
• A more adaptable and realistic model is needed to enhance patient safety analysis.

Purpose of the Study:

• To introduce the 'hot cheese model' as a more advanced alternative to the Swiss cheese model.
• To provide a more flexible and dynamic framework for understanding accident causation in complex systems.
• To encourage more in-depth analysis of patient safety incidents.

Main Methods:

• Conceptual development of the 'hot cheese model'.
• Comparative analysis with the existing Swiss cheese model.
• Application of the model to complex system safety.

Main Results:

• The hot cheese model portrays defense layers as dynamic and active, acknowledging that more defenses can introduce more hazards.
• It offers a more realistic and flexible visualization of accident causation.
• The model facilitates a deeper discussion and analysis of safety incidents.

Conclusions:

• The hot cheese model provides a more comprehensive and nuanced understanding of patient harm.
• Its dynamic nature allows for a more accurate representation of complex system interactions.
• This model enhances the potential for improved patient safety strategies and incident investigation.
