What is national health information?

「National health information」 is information on the medical treatment history, drug prescription history, and health checkup results of 1 million people who are eligible for national health insurance (about 2% of the entire population).
In order to meet public interest in health care and industry demands, the National Health Insurance Corporation has been opening national health information on an annual basis since 2002 through a public data portal.

How can I use it?

It is expected that it will be possible to conduct academic research to improve public health, develop content for the healthcare industry, and prepare sales strategies by utilizing a large sample of 「National Health Information」.
For example, a pharmaceutical company can use prescription history information by province and drug ingredient to establish a strategy for related sales activities.
Companies that utilize body size will be able to systematically develop new products using information such as height, weight, and waist circumference.
