I currently work in a critical care unit that has instituted a policy of open visiting hours. Aside from a two hour time period in the morning (0630-0830) and the evening (1830-2030), up to three visitors are permitted to be in the patient's room at all times thoughout the day. I am told that this a growing trend in the critical care environment across the country, but I have found it to be a source of stress and frustration. Any thoughts?
