Researchers have been interested in probing how the environmental factors associated with allergic diseases affect the use of medical services. Considering this demand, we have constructed a database, named the Allergic Disease Database, based on the National Health Insurance Database (NHID). The NHID contains information on demographic and medical service utilization for approximately 99% of the Korean population. This study targeted 3 major allergic diseases, including allergic rhinitis, atopic dermatitis, and asthma. For the target diseases, our database provides daily medical service information, including the number of daily visits from 2013 and 2017, categorized by patients' characteristics such as address, sex, age, and duration of residence. We provide additional information, including yearly population, a number of patients, and averaged geocoding coordinates by eup, myeon, and dong district code (the smallest-scale administrative units in Korea). This information enables researchers to analyze how daily changes in the environmental factors of allergic diseases (e.g., particulate matter, sulfur dioxide, and ozone) in certain regions would influence patients' behavioral patterns of medical service utilization. Moreover, researchers can analyze long-term trends in allergic diseases and the health effects caused by environmental factors such as daily climate and pollution data. The advantages of this database are easy access to data, additional levels of geographic detail, time-efficient data-refining and processing, and a de-identification process that minimizes the exposure of identifiable personal information. All datasets included in the Allergic Disease Database can be downloaded by accessing the National Health Insurance Service data sharing webpage (https://nhiss.nhis.or.kr).
研究人员一直热衷于探究与过敏疾病相关的环境因素如何影响医疗服务的利用。考虑到这一需求，我们构建了一个名为“过敏疾病数据库”的数据库，该数据库基于国民健康保险数据库（NHID）。NHID 包含了大约 99%的韩国人口的人口统计和医疗服务利用信息。本研究针对三种主要的过敏疾病，包括过敏性鼻炎、特应性皮炎和哮喘。对于目标疾病，我们的数据库提供了 2013 年至 2017 年的每日医疗服务信息，按患者的住址、性别、年龄和居住时间等特征对每日就诊次数进行分类。我们还提供了其他信息，包括每年的人口、患者数量以及按邑、面、洞（韩国最小的行政单位）的地区代码划分的平均地理编码坐标。这些信息使研究人员能够分析特定地区过敏疾病的环境因素（如颗粒物、二氧化硫和臭氧）的日常变化如何影响患者医疗服务利用的行为模式。此外，研究人员还可以分析过敏疾病的长期趋势以及日常气候和污染数据等环境因素对健康的影响。该数据库的优势在于数据易于获取、具有更多层次的地理细节、数据精炼和处理效率高，以及最小化可识别个人信息暴露的去识别化过程。过敏疾病数据库中包含的所有数据集都可以通过访问国民健康保险服务数据共享网页（https://nhiss.nhis.or.kr）下载。
