Question
There is a severe shortage of critical care doctors and nurses to provide intensive-care services in hospitals. To offset this shortage, many hospitals are using electronic Intensive-care units (eICUS) to help provide this care to patients. eICUS use electronic monitoring tools and two-way communication through video and audio so that a centralized staff of specially trained doctors and nurses-who can be located as far away as Australia-can
provide critical care services to patients located in remote hospitals without fully staffed ICUS. One of the most important metrics tracked by these eICUS is the time that a patient must wait for the first video interaction between the patient and the eICU staff. Suppose the following is a sample of 40 patient waiting times until their first video interaction with the eICU staff.
