Optimizing the Integration of the Patient Admission Process in a Swiss Rehabilitation Center with Multiple Parties

This paper explores challenges and solutions for the interoperability between Swiss hospitals, rehabilitation centers, and insurance companies with a focus on the patient admission process. It addresses issues such as inconsistent data formats, little to no structured interfaces between institutions, and limited trust in a central authority. The study proposes two alternative architectures: a centralized system with encrypted data and a decentralized system using public key infrastructure (PKI). The findings suggest a hybrid model combining centralized and decentralized features as a feasible solution to enhance collaboration, optimize admissions, and improve patient care.
