When a patient arrives at the ED (emergency department) of the Medical Center of DeVry, demographic and insurance information is obtained. The ED registration clerk checks the facility master patient index (MPI) and either updates information if the patient has previously been treated at the facility or enters the information if this is the patient’s first visit. The triage nurse takes a medical history and performs an initial clinical evaluation. This information is entered into a computerized ED encounter form and an automated triage system categorizes the patient. The triage systems assign an available ED bed in the bed assignment system. The patient is put on the schedule to be seen by an ED physician. The ED scheduling system tracks a patient in the ED and captures information on diagnosis, treatments, provider interaction, and amount of time a patient spends in the ED. An ED physician sees the patient by schedule order. The physician performs an examination, orders tests, writes prescriptions, makes a diagnosis, and makes a decision about patient disposition. The ED physician enters medical history, examination information, diagnosis, and patient disposition into the computerized patient EHR system. The ED physician enters medication and test orders into the order-entry system, and orders are automatically routed to the clinical laboratory, radiology, and pharmacy information systems. Given the above case study, construct a block diagram that shows the boundaries of the ED information system; components of the ED information system; and their relationships, system inputs, outputs, and interface with systems outside the ED information system. You will be creating your block diagram in Microsoft Visio, so be sure to view DeVry’s and the . Once you have completed your diagram, submit it to the Dropbox. The objective of this assignment is to promote an understanding of systems theory: a group of component parts, separated by a boundary from other systems that work and interact with one another to achieve a common goal. After completing this assignment, you should understand that a change in one component will affect other components within the system or outputs that feed other systems. NOTE: check out the various tutorial links regarding Visio in the Webliography section. There are tutorials available in the DeVry Hub, as well as free tutorials available on the Microsoft website. The block diagram should show the boundaries of the ED information system. Click a shape to select it and do one of the following: Add the components of the ED information system and their relationships.
