Hospital Admission Information System Description. The local hospital Emergency Room (ER) admits and treats patients that present themselves for medical treatment. Each patient is assessed by a triage nurse, who performs a preliminary assessment to determine the priority level of the patient's presenting complaints. If the patient needs immediate attention, the triage nurse provides enough intervention to stabilize them. An ER patient record is initialized, containing the patients's name and complaint. A priority level is added to the record by the triage nurse. Patients are released from "triage" into the ER proper once there is an available Emergency Room Physician who can provide further assessment, treatment diagnosis and referrals as needed. ER physicians treat patients in the order of the triage queue, which manages an order determined firstly by the triage nurse's assessment and secondly by the amount of time that has passed since the patient registered
