What are the advantages and disadvantages of a mirrored design? Provide rationales for your answers
You have been asked to join the team designing the new suite of four operating rooms (ORs). The team has selected a single-corridor layout with mirrored design for the paired ORs (whereby the OR layout is a mirror image of the layout in the adjacent OR).
What will be an ideal response?
Answer:
Advantages: This is also known as ‘reverse-handed' because of the reversal (inverting) of the image on one axis. It has been common practice in healthcare design to use back-to-back rooms in pairs or in module combinations. Mirror image planning can provide cost and planning efficiencies.
Rationale: The mirror-image design creates a potential to share electrical and plumbing services as well as circulation spaces, reducing costs.
Disadvantages: Staff efficiency can be decreased by mirror-image designs. This design can also make it more difficult for surgical teams to adjust when relocated to a different OR if the services are in the opposite position (see also advantages of single-handed above).
Rationale: The opposite placement of resources and services between ORs may confuse new staff and may increase the risk of staff errors.
