Abstract
We constructed an electronic medical record system in the Department of Radiology and described medical records of patients who entered hospital to receive radiotherapy. Using this system, we studied the usefulness of the electronic medical record system from the readers' point of view. We measured time taken to read the medical records while checking important items of radiotherapy, and tried to investigate the usefulness of the electronic medical record system compared with a conventional medical record system. In selecting important items of radiotherapy, we referred to the database of radiotherapy medical records made by JASTRO. The average time for reading electronic medical records and conventional medical records were 130.0 seconds and 249.9 seconds respectively (p=0.0001). The frequency of descriptions of important items were not statistically different. As to primary site and external radiotherapy field, they were not statistically different, and regarding the method of therapy, this was the same.
