Some hospitals have installed teleconferencing systems that allow doctors and nurses at a central facility (either in the same building, at a central location serving several local hospitals, or in rural locations another more urban facility) to collaborate with on-site staff and speak with patients (a form of telemedicine ). This is variously called an eICU , virtual ICU , or tele-ICU . Remote staff typically have access to vital signs from live monitoring equipment, and to electronic health records so they can get a broader view of a patient's medical history. Often bedside and remote staff have met in person and may rotate responsibilities. Such systems allow hospitals to double-check that correct procedures are being followed for the patients most vulnerable to mistakes, and to use access expertise remotely to keep patients that would otherwise have to be transferred to a larger facility, and have demonstrated a significant decrease in mortality.
