The Biomedical Instrumentation DepartmentatThomas Jefferson University Hospitalmaintains most of the clinical equipment owned by the hospital and provides support to six other hospitals, as well. In order to document these services, a computerized support system has been developed. This system maintains the inventory of equipment, documents the occurrence of repair and preventive maintenance procedures, generates lists of items due for maintenance and inspection, and prints reports and summaries of all activities performed by departmental staff. The system was designed for ease of use and requires a minimum of training for personnel who use it.
