Abstract: A multiple user computerized clinical care system and method of using it, include the use of a group of terminals communicating with a central computer system for sending and receiving patient information for storage and retrieval purposes. The system and method includes managing patient information variance requests, by storing the variance information in the order in which the variance requests are received. The terminals are then supplied with the stored variance information to enable the terminals of the computer system to receive current updated patient information for a given patient substantially concurrently as the updated information is being entered at a plurality of the terminals, without causing any user to wait for the current variance information.
