I think you could certainly say it was clinical in terms of intensive care. The ICU staff have special training and skills, so doubling up such wards is wasteful not only in terms of equipment but also in staffing. But sex of the patient is not so relevant because if a patient is in an ICU, they are likely to be unconscious or deeply sedated and certainly will not be capable of wandering around. ICUs are staffed 24 hours a day, as are A&E units.
