10264-CS-25 Near-future medical collaboration system for brain tumor treatment

Abstract Background Our Neurosurgery Department started inter-hospital medical collaboration using hotline telephones in 2000 and has been sharing images using videophone and smartphones since 2002. Currently, an image sharing system using Synapse (Fujifilm medical) is deployed at 15 hospitals in and outside of Yamaguchi Prefecture, and about 300 Doctor to Doctor (D2D) consultations are conducted annually. The consultations conducted so far have been D2D telephone consultations for acute diseases, mainly stroke and head trauma. Problem While it is difficult to maintain advanced medical care of brain tumor in depopulated areas, a system is needed to enable consultation on treatment plans and advanced medical care at hospitals in depopulated areas in order to minimize the burden of patient travel. To achieve this, a system that (1) enables easy communication, (2) makes images available to all hospitals, and (3) is low-cost is needed. Methods To solve these problems, we established MEDIMONY, the first start-up company from our department, and have been developing the system. The system is based on a zero-touch system that allows hospitals in underpopulated areas to communicate with each other without having to operate the system. The zero-touch system is operated with ordinary tablets and uses LTE for communication, so Wi-Fi is not required for hospitals in depopulated areas. Doctor to Patient (D2P) with D has been in operation since May 2025, using this system to provide chemotherapy at hospitals in underpopulated areas. Future The company is also developing a system to share monitor images from electronic medical records without the need for an image sharing system, aiming to enable consultations at all hospitals. The company will continue to develop D2D and D2P with D for brain tumor patients in Yamaguchi Prefecture, aiming to create a model project that will enable equalization of medical care in depopulated areas.
