BMH encompasses many conditions and a multitude of centers for treatment. The level of concern for the safety of patients and staff due to the design of the built environment is not the same in all parts of a behavioral health facility.

When designing a facility, best practice is to use a patient safety risk assessment (PSRA) matrix. This tool relates an opportunity for a patient to be alone to a level of risk of self-harm.

A combination of these factors help to determine the level of risk involved with each room in the facility.
