The Computerized Notation System (CNS). A microcomputer system for rapid entry of notes by physicians and nurses

A computerized notation system has been developed to produce a digital medical data base. Use of a separate physical record for every 1-4 patients allows several years of accumulated data to be easily accessible for patient "summaries" or admission "histories and physicals." To facilitate entry of data in the system, the physician is provided with a portable, complete computer system (HP-85, or Epson HX-20), a user-defined two-letter dictionary, and a program that produces all elements of the manual paper charting system. "Overview" and research data bases are developed from the digital medical data base records. In this paper, we report the efficiency of use of this computerized notation system in private outpatient and inpatient practice.
