How are things done in your units?

I am trying to find out how things work in other hospitals as this has become a topic of debate in mine. Is there a time frame in which physicians have to see a patient after an admission to a critical care unit in your hospital? I feel that if a patient's condition warrants an admission to a critical care unit, it also warrants a visit from the admitting physician. However, in my unit, it can be HOURS before a patient is seen by a physician after admission, even if the patient is a stat-flight or direct admit from another facitily. My concern is that this puts both the patients and the nurses in my unit at risk. Please respond. Am I being overly cautious in wanting my patients seen by their physician, instead of just activating standing orders or is the practice in my facility unsafe? ~Sarah
