User Interface Preferences in a Point-of-care Data System

Point-of-care data entry is an important part of a clinical information system. Unfortunately, many health care providers refuse to perform data entry because they feel computers are difficult to use and require more time than traditional paper based forms. We designed a user interface for entry of outpatient visit information that gives the health care provider several alternative methods of entering data. The system audits the use of the individual interface elements and measures the time required for completion of the data entry.
