数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

個人及研究資料將於研究結束後保存 5 年。患者資料將以最謹慎的方式處理,不會以任何形式侵犯患者隱私。資料將儲存在安全的櫃子和/或電腦中,並由密碼操作。為保障病人私隱,所有研究資料將按照醫管局/醫院處理/儲存/銷毀病人醫療記錄的政策處理。電子資料將儲存於醫院的保密電腦內,並設有存取限制。USB 裝置不會用作儲存病人資料或個人資料。個人資料(姓名、香港身份證號碼、門診/醫院號碼、地址及任何其他可識別個人身份的資料)不會記錄在計劃的資料單或電子檔案內。研究代碼將被使用。載有研究代碼與患者身份之間的連結資訊的電子檔案文件將不會包含任何其他資訊,並將與研究資料檔案或資料單獨立保存,其安全性與醫療記錄相同。任何包含個人身分識別資訊的文件或電子檔案將被視為醫療記錄的一部分,並將根據醫院政策以相同的嚴格安全規定處理。所有調查員均有責任處理和保護資料。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The personal and study data will be kept for 5 years after the study. Patient data would be handled with utmost care taking care not to breach patient's privacy in any form. The data would be stored in secure cabinets and/or computers which would be password operated. To protect patient privacy, all research data would be handled in line with HA / Hospital’s policy in handling / storage / destruction of patients’ medical records. Electronic data would be saved in secured computer of the hospital with restricted access. USB Device would not be used for patient information nor personal data. Personal data (name, HKID, OPD / hospital numbers, address and any other personal identifiable information) would not be recorded on the project’s data sheets or electronic files. A study code would be used instead. The document of electronic file containing the linkage information between the study code and the identity of the patient would not contain any other information and would be kept separate from the study data files or data sheets with the same stringent security as the medical record. Any documents or electronic files containing personal identifiable information would be considered as part of the medical record and would be dealt with the same stringent regulations of security according to the hospital policies. All the investigators would be responsible for data handling and protection.
