EHR Chapter 3

information processing cycle the sequence of events that includes four components: input, processing, output, and storage
input the first component of the information processing cycle; data entered by the user of an EHR system (e.g., the patient’s first name, last name, identification number)
processing the second component of the information processing cycle; takes data and makes the information usable within the system
output the third component of the information processing cycle; data produced that provides meaningful information for the user
storage the fourth component of the information processing cycle; patient information is stored so that it can be retrieved, added to, or modified for later use
storage devices a place where data for the EHR may be stored, such as on a dedicated server at the healthcare facility or on a server provided by a vendor; if an EHR system is networked, then the storage may exist on the healthcare system’s server
