摘要

目標：提供全民健康保險學術資料庫基本資料檔的使用經驗，簡述利用資料庫計算醫院數等基本數據的相關問題及因應對策。方法：採用單一檔單一數值、費用檔連結、外部資料連結三種計算方法，並與衛生統計、全民健康保險統計比較結果。結果：三種方法計算結果有所出入。使用該資料庫的重要問題包括：(1)資料處理：醫院代號變換造成不同檔案間連結的困難；(2)數量計算：資料庫流水帳的特性使計算手續繁雜；(3)誤差估計：部分計算結果與其他資料差異很大，且難以估計誤差。結論：該資料庫內容豐富，惟處理程序繁複，資料的動態本質應是以上問題的主要原因。國衛院宜作較詳細的使用說明，並考慮與其他資料的連結，以發揮全民健保資料庫的最大功能。(台灣衛誌 2002；21(2)：150-155)

Objectives: To share experience on using the National Health Insurance Research Database to calculate basic information, including the number of hospitals, physicians, and beds, and claims amount. Methods: Three methods were used to calculate those figures: single file-unique value, c1aims-data-linking, and outside-source-linking. The results were compared to those from the Health and Vital Statistics and the National Health Insurance Annual Statistics Report. Results: Three types of difficulties in using the database are as follows: (l) Data management: hospital 10 changes causes problems in linking files within the database. (2) Figures-calculating: the data in fact record a series of events, like accounting journals. Therefore, many steps need to be taken to produce correct figures, as in making ledgers from journals. (3) Bias assessment: estimates generated from the database can be quite different from those of other sources. However, it is difficult to perform a valid bias assessment. These problems are likely to have resulted from the dynamic nature of the database. Conclusions: The database provides rich information on institutional and contractual changes. However, clearer user instructions are needed. In addition, functions of the database can be enhanced if it is allowed to match with other major databases.(Taiwan J Public Health. 2002;21(2):150-155)
