| Research Abstract |
Intraoperative pathology diagnosis (IPD) by telepathology (IPD-TP) is a field of telemedicine, which can improve differences in quality of advanced medical managements in the regional areas. We started this telemedicine in November, 1997 and, supported by the "Grant-in-Aid for University and Society collaboration" of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), we challenged to expand our IPD-TP network in April, 2000. With obtaining the informed consent from patients who were eligible for this telemedicine, IPD-TP was attempted to 249 patients by the end of March, 2002.
Among these patients, 222 patients were correctly diagnosed, but 9 patients had erroneous diagnoses. Diagnoses in 6 patients were approved and those in 12 patients were reserved. The rate of clinically significant diagnostic accuracy was calculated to be 96.2%. Average time required to prepare a frozen section was 21.7 min and that to make a diagnosis for a specimen was 7.8 min.
Our network of this IPD-TP was made open to regional clinics via one pre-existing regional medical project. However, support of tele-surgery, which had been challenged by another regional medical project, by our IPD-TP could not be performed because of the absence of patients who were eligible for this collaboration during the period of our project.
Our interim data were made open to a regional medical society and a questionnaire was given to an ordinary people group. Because they though that our project was important, and because the number of patients, to whom IPD-TP was provided, was increasing, it is concluded that our project to expand IPD-TP network and to make this telemedicine being of practical use is successful. Since broad band-based information technology is now available, it is considered that image transmission by this can decrease time required for diagnosis and improve our diagnostic accuracy.
