Medical Diagnosis & Prescription Automation System High Level Data Diagram

I drew a high level system diagram to explain the data requirements for a professional Medical Diagnosis & Prescription Automation System (MDPAS). The core elements of a MDPAS are the ones highlighted in pink. The medical diagnosis, symptoms and prescription relationship determine the rules and logic to make professional medical prescription decisions.

There are 55000 unique codes of disease and 100,000 medical diagnosis terms in the world. And one diagnosis contains many symptoms. Therefore medical prescription is a highly complicated and sophisticated medical decisions.

So where did the Medisafe acquire the prescription & symptoms or prescription & medical test results relationship dataset? Any AI rules and logic to replace professional medical decision should requires statistic result support, medical certification and the approval from the Hospital Authority.
