目的：建置一網頁應用編程介面以整合放射腫瘤部門現存不同廠牌放射治療儀之治療記錄，並應 用於放射腫瘤電子病歷化與醫院內現行醫療資訊系統之連結。 材料與方法：我們研究剖析三套商用記錄暨驗證系統之結構和欄位並打造一網路應用編程介面， 其包含功能如下：1. 透過 PHP 和標準 SQL 語言將所需欄位資料由記錄暨驗證系統資料庫中取回， 2. 將取回資訊整理並重新編排，3. 病人之治療記錄透過 JSON 格式傳回至醫院系統。我們統計使 用此系統、商用軟體、紙本病歷來查詢 20 位病患之治療記錄所費時間，以評估此系統帶來之效 益。 結果：此系統獨立運作在不影響現存放射治療工作流程之下，可達到與醫院系統間資訊交換，任 何具備權限的使用者，皆可以在任意時間、在醫院各個角落，透過互動式網頁，查詢病患即時 治療記錄，節省紙本病歷的運送及人為鍵入資料的誤差。與調閱紙本病歷（時間：927 ± 2541 秒）、分別進入各商用軟體查詢（時間：17.1 ± 16.2 秒）相比，此系統（時間：1.08 ± 0.56 秒） 也顯著的減少治療記錄查詢時間。 結論：此系統自動化整合了不同廠牌治療儀器的治療記錄，打破了時間、地域和廠牌系統的藩 籬，對放射治療病歷全面電子化及電子化管理有極大幫助，也節省使用者查詢治療記錄時間。

Purpose : The purpose of this study was to develop a web application programming interface to integrate records and verify systems of various vendors and help bridging hospital information system and electronic radiotherapy medical record. Materials and Methods : The structure and fields of three commercial records and verify systems were identified and studied. A web application programming interface was implemented to perform the following three tasks: 1. Pre-defined fields were queried from each database using PHP and standard SQL language, 2. The retrieved data were rearranged and consolidated to fulfill clinical needs, 3. The patients’ treatment histories were summarized and exported to hospital information system via JSON format. The performance of the web API, commercial applications, and with manual transfer of paper charts were measured by analysis of query time for twenty patients. Results : The system has been transparently incorporated into our radiation treatment planning workflow. The website-based database interface has allowed authorized users with minimal training to extract patient’s daily treatment from the database anytime and anywhere in the hospital. The query time significantly decreased using this system. Conclusions : The web application programming interface can integrate patient’s treatment data from different commercial treatment machines and export to hospital information system. The application breakthrough the vendor’s limitation, and is helpful in developing radiotherapy electronic medical records.
