Physical or built environment or environment design in the hospital

Physical or built environment or environment design in the hospital

"Health Facility Environment"[Mesh] OR "Environment"[Mesh:NoExp] OR "Environment Design"[Mesh] OR "Facility Design and Construction"[Mesh]

combine the above with the relevant MeSH for the department/unit or facility in your question (e.g. "Psychiatric Department, Hospital"[Mesh] OR "Hospitals, Psychiatric"[Mesh])

You can also try keywords such as:
"physical environment"[tiab] OR "built environment"[tiab] OR architectur*[tiab] OR "interior design"[tiab]
however, for my question these only resulted in 1 additional article, so not especially helpful.
