Development and use of a computer system in a radiotherapy department: SISGRAD.
SISGRAD, the interactive computer system of the Antoine-Lacassagne Cancer Center Radiotherapy Department, has been operational since January 1982. It completes the computerized dosimetry system installed several years earlier and is fully integrated with the institution's central network. SISGRAD is in charge of surveillance of the radiotherapy treatments given by the Center's three radiotherapy units (1400 patients per year); it is also used for administrative purposes in the Department and physically connects all of the Department's operating stations. SISGRAD consists of a series of microcomputers connected to a common mass memory; each microcomputer is used as an intelligent console. SISGRAD was developed to guarantee that the treatments comply with prescriptions, to supply extemporaneous dosimetric data, to improve administrative work, and to supply banks with data for statistical analysis and research. SISGRAD actively intervenes to guarantee treatment quality and helps to improve therapy-related security factors. The present text describes the results of clinical use over a 4-year period. The consequences of integration of the system within the Department are analyzed, with special emphasis being placed on SISGRAD's role in the prevention and detection of errors in treatment prescription and delivery.
