The Miami Heart Institute's Electrical Safety and Preventive Maintenance Program has been designed as a stand-alone component of a large-scale, computer-based hospital information system. It ensures regularly scheduled routine inspections, preventive maintenance and, where applicable, calibration of the institution's diagnostic, therapeutic and other electrical equipment used in patient care. The program also schedules and documents inspection of buildings, service equipment and grounding systems. The software consists of a single program which permits on-line entry, editing and display of information as well as automatic, unattended generation of printed forms. This program has been in continuous use since May, 1974.
