It's time for the mandatory use of simulation and human factors in hospital design.

Building a new healthcare facility is complex and poses challenges in delivering a facility that is fit for purpose and designed to minimise latent environmental and process errors. This article summarises what the disciplines of Human Factors/Ergonomics and Simulation can offer to the design and testing of new hospital builds. It argues the incorporation of both disciplines throughout the planning, design, commissioning and operations phases of the building project can minimise latent safety risks to promote patient safety and staff well-being across the building lifecycle. Future directions and policies should include incorporation of human factors design and mandatory process testing before opening.
