MEI's Secondary-Use Electronic Medical Record Data Scale Exceeds 6 Million

Medical Engineering Research Institute Co., Ltd. (headquartered in Tsu City, Mie Prefecture; President and CEO: Kuniō Kasazaki; hereinafter “MEI”) announced that the scale of secondary-use data derived from electronic medical records (EMRs) it provides has exceeded 6 million patients. Since announcing the milestone of 5 million in March 2026, collaborations with medical institutions have continued to expand smoothly, adding another 1 million patients’ worth of data.
