Medical Laboratory Information Systems (LIS)
Computerization of clinical laboratories began with attempts to automate the analysis of specimens in the early 1960s. At that time, laboratory instruments were being developed that generated analog signals that could be converted to digital information, which could be processed and stored on computers. Since computer processing was primitive during this period and the ability to store and retrieve information was limited to paper tape, punched cards and magnetic tape, early attempts at clinical laboratory computerization, while heroic, were not highly successful. Later on, concomitant with the development of disk storage and retrieval of laboratory data, a number of commercially available systems emerged during the decade beginning with the mid-1960s. Commercially available systems during this period included B-D Spear (Waltham, Massachusetts), Laboratory Computing, Inc. (Madison, Wisconsin), The Medlab Company (Salt Lake City, Utah), Community Health Computing (Houston, Texas), Honeywell (Minneapolis, Minnesota), Diversified Numerical Applications (Minneapolis, Minnesota), Advanced Medical Systems (New York, New York), Berkeley Scientific Laboratories (Hayward, California), and Medical Information Technology (Cambridge, Massachusetts).
