国民健康保险服务-国民样本队列（NHIS- nsc）是由韩国国民健康保险服务（NHIS）建立的以人口为基础的队列。构建队列的唯一目的是向公共卫生研究人员和政策制定者提供有关公民使用健康保险和健康检查情况的有代表性的有用信息。韩国的全民健康保险制度是1963年根据《国民医疗保险法》建立的，1977年以500人以上的企业为对象。1989年，在实行全民医疗保险仅12年后，就实现了全民医疗保险，这是全球实现这一目标最快的国家。1 2000年，为了在韩国有效运作，一个单一保险公司系统，即全国健康保险制度，通过整合超过366个医疗保险组织，推出了1全国健康保险制度，提供预防、诊断、疾病和伤害治疗，以及康复、出生、死亡和健康促进方面的福利。目前，NHIS维护和存储医疗保健使用和处方的国家记录。由于该系统的有效性以及与公共卫生和医学研究的相关性，NHIS记录引起了学术界的兴趣。为了满足这一需求，建立了一个人口数据库，即“国家健康信息数据库” 2，其中载有韩国公民的个人信息、人口统计和医疗数据，这些公民被分类为受保险的雇员、受保险的自营职业者或医疗援助受益人。全国健康保险计划是根据参与者向医疗服务提供者索偿的医疗帐单费用编制的。数据根据医疗日期而不是索赔日期重新排列。然而，由于NHID不可避免的大量可用性有限，以及个人信息的保密性不足，国家卫生研究院决定构建一个具有代表性的样本数据库，即国家卫生研究院-国家卫生研究院，该数据库拥有大量的代表性信息，不需要为研究和政策制定提供隐私监管。
The National Health Insurance Service–National Sample Cohort (NHIS-NSC) is a population-based cohort established by the National Health Insurance Service (NHIS) in South Korea. The sole purpose of constructing the cohort was to provide public health researchers and policy makers with representative, useful information regarding citizens’ utilization of health insurance and health examinations. Korea’s universal coverage health insurance system for all citizens was initiated in 1963, based on the National Medical Insurance Act, and was introduced for companies with over 500 employees in 1977. Universal healthcare coverage was achieved in 1989, only 12 years after its introduction, which is the fastest this has been achieved globally. 1 In 2000 a single-insurer system, the NHIS, was launched by integrating more than 366 medical insurance organizations, for efficient system operation in Korea. 1 The NHIS provides benefits for prevention, diagnosis, disease and injury treatment, as well as rehabilitation, births, deaths and health promotion. Currently the NHIS maintains and stores national records for healthcare utilization and prescriptions. The NHIS records have garnered academic interest due to the effectiveness of the system and relevance to public health and medical research. To meet this interest, a population database has been developed, the ‘National Health Information Database’(NHID) 2 containing personal information, demographics and medical treatment data for Korean citizens, who were categorized as insured employees, insured self-employed individuals or medical aid beneficiaries. The NHID was generated using participants’ medical bill expenses claimed by medical service providers. Data were rearranged according to date of medical treatment rather than date of claim. However, due to limited useability of the NHID’s unavoidably large volume and the lack of confidentiality regarding personal information, the NHIS decided to construct a representative sample database, the NHIS-NSC, with a substantial volume of representative information that does not require privacy regulation for research and policy development.
