In patients who are a fall risk, it is important to assess their living environment to remove factors which might contribute to a fall. Loose rugs are a significant fall hazard since patients frequently will trip or get tangled up in them. Other effective preventative measures are to illuminate the room well, remove any debris or spills, and to install handrails or guardrails as appropriate. Automatic lighting might help with illumination, but it would likely dim the lights at night, as well, which would increase the risk for a fall. Stairs and a sunken living room are fall hazards.
