OPERe Inc. (Headquarters: Tokyo, Representative Director: Yuka Sawada, hereinafter OPERe), aiming to be a communication hub for patients and healthcare providers, has begun data integration between the anamnesis and questionnaire function of its patient communication system "PokeSapo" and "Yahgee (Yagii)", a medical document management and operations support solution provided by Fujifilm Medical Co., Ltd. (hereinafter "Fujifilm Medical"). This integration will utilize Epson's software (DCPSE1) and scanners as document scanning solutions. This integration will enable the secure import of questionnaire information entered by patients via their LINE app or in-hospital tablets into the hospital's internal system, which operates in an isolated network (on-premises) environment that cannot be externally connected. This data can then be utilized for creating medical documents such as inpatient medical care plans on Yahgee. ■ Background and Challenges In the field of admission and discharge support, the manual input and transcription of questionnaire information collected from patients in advance into electronic health records (EHRs) and departmental systems represent a significant burden. On the other hand, many hospital EHRs and document management systems operate in isolated network (on-premises) environments, disconnected from external networks for security reasons, posing a challenge for direct data integration from cloud services. OPERe has received requests from multiple medical institutions, including hospitals that have implemented Yahgee, to "utilize patient information acquired through PokeSapo directly within Yahgee." Through cooperation with Fujifilm Medical and Epson, this initiative achieves realistic and secure data integration that overcomes the barrier of isolated networks by using paper (printing) and scanning as a "bridge." ■ Integration Overview and Data Flow Patient questionnaire responses are imported into Yahgee through the following flow: Patient/Fa
