ABSTRACT
The beginning of EHR (Electronic Health Record) can be traced back to the development of the Medical Markup Language (MML) from 1995 to 2000. In 2001, EHR with MML as a database structure was developed and expanded to Kumamoto, Miyazaki, Tokyo, and Kyoto (Dolphin Project). After that, the need for medical information management at the national level was recognized, and the need for secondary use of medical information was also recognized, and in 2015, the national level version of the EHR, the “Millennial Medical Record Project” began. The number of connected medical institutions reached 106 in the four years up to FY2018. In December 2019, the Life Data Initiative, a general incorporated association, became the first certified company under the Next Generation Medical Infrastructure Law, and is operating with the aim of achieving independent profitability, including the EHR department, which does not depend on subsidies.
