The main impact on patient outcome after hospitalisation is treatment, provision of care and patient-professional relation. However little attention has been directed to the impact the physical environment has on patient’s outcome. In a joint collaboration between Swedish and Danish environmental workers and nurses, a literature study was conducted. The study showed lacking evidence of what the ideal room should look like or contain. On the other hand knowledge on single elements were found; light, smells, sounds, art, social life, safety and infection control. Common themes were patients’ opportunities for self-determination (like room temperature or brightness of light), the room’s flexibility, the possibility of remaining in contact with relatives and the outside world, having a private space, not being alarmed by strange sounds or smells and consideration about patient safety. This is knowledge that be used when planning renovation or building new hospitals, or when engaging in discussion about how to improve care.
