A low-cost, computerized data management system has been developed on a Digital Equipment Corporation PDP11V03 computer system with dual floppy discs using BASIC in a time-shared configuration. The system collects, updates, and stores patient information on floppy discs for later retrieval and statistical analysis. All application software is written in BASIC to simplify changes or expansion, and to reduce the software labor costs for transferring the system to other low-cost microprocessor systems currently on the market. This system has been used by several hospital departments for data management and has proven to be a useful tool.
