1、涉及面广,每个人都有健康信息,一个区域就有几千万,我认为在信息化建中涉及面最广的就是医疗卫生。2、涉及部门非常多,医改的时候当时国务院成立协调小组,十几个部在里面,包括疾病控制、药品监督等等,真的非常复杂。3、数据量非常大,每个人—份健康档案,中国十几亿人就要十几亿份。4、数据增长又非常快,每天都产生大量的数据,每个人到医院就要产生。 1. Involving a wide range of people. Everyone has health information. There are tens of millions in a region. I think that the most widely involved in informatization construction is health care. 2. There are a lot of departments involved. At the time of the medical reform, the State Council established a coordination group and more than a dozen departments, including disease control, drug supervision, etc., were really complicated. 3, the amount of data is very large, each person - a health file, more than a billion people in China will have more than 1 billion. 4, data growth is very fast, a large amount of data every day, everyone will have to go to the hospital.
