On the hierarchy of safety interventions, system or product redesign falls in the level of highest effectiveness. For example, if you want to prevent nurses from infusing formula into an IV line, you redesign the formula tubing so that it cannot physically fit into IV devices.
Reorganizing a workspace may be used as a safety intervention. In the Human Factors blog, they talk about organizing by taxonomy vs taskonomy.
They use the example of making a kitchen more user friendly but this concept of taskonomy can definitely be applied to hospital areas.
