COSTAR or Computer-Stored Ambulatory Record was developed by the Laboratory of Computer Science at Massachusetts General Hospital between 1968 and 1971 for Harvard Community Health Plan by Octo Barnett and Jerome Grossman. COSTAR operates using the MUMPS programming language. MUMPS was widely used in the 70's & 80's for medical applications.
COSTAR was one of the first programs that used "reminders" that were generated once a patient's profile was used. This aided in proper observance of clinical guidelines by the practitioner [Luo JS 2006].
COSTAR relied on free-text entries, primarily to allow specificity of physicians' notes. Within the first 2 years, the system had records for 20,000 patients resulting from 80,000 visits. But the free-text format made summary analysis of medical records impossible. A review of natural-language parsing in 1983 found that of 233 throat cultures for Beta Hemolytic Strep Group A, 90 were falsely labeled as normal by a natural-language processor that looked for specific strings in the free-text entries.
Researchers in 1983 urged a new system based on a series of menus that limited the data entry, in some areas, to pre-coded text that could be more accurately analyzed. They noted new developments with graphical interfaces that included "windows" that could be navigated with a new computer accessory, the "mouse."
