Note. The mean SCW is the sum measured in feet of the average distance from a patient bed to clean supplies, charting facility, and body-waste disposal. The percentage of beds in private rooms was calculated by dividing the number of private-room beds by all beds. Visibility was calculated by dividing the number of beds that allowed a view of the patient’s head and hands (upper third of body) from a charting area. Bed is any bed deemed to be in use or eligible for use at the time of the study.
