Recent healthcare policies have influenced the manner in which patient data is handled in research projects, and the regulations concerning protected health information have become significantly tighter. Thus, new procedures are needed to facilitate research while protecting the confidentiality of patient data and ensuring the integrity of clinical work in the expanding environment of electronic files and databases. We have addressed this problem in a university hospital setting by developing the Tampere Research Archival System (TARAS), an extensive data warehouse for research purposes. This dynamic system includes numerous integrated and pseudonymized imaging studies and clinical data. In a pilot study on asthma patients, we tested and improved the functionality of the data archival system. TARAS is feasible to use in retrieving, analyzing, and processing both image and non-image data. In this paper, we present a detailed workflow of the implementation process of the data warehouse, paying special attention to administrative, ethical, practical, and data security concerns. The establishment of TARAS will enhance and accelerate research practice at Tampere University Hospital, while also improving the safety of patient information as well as the prospects for national and international research collaboration. We hope that much can be learned from our experience of planning, designing, and implementing a research data warehouse combining imaging studies and medical records in a university hospital.
最近的医疗保健政策影响了研究项目中患者数据的处理方式，有关保护健康信息的规定变得更加严格。因此，需要新的程序来促进研究，同时保护患者数据的机密性，并确保在电子文件和数据库不断扩展的环境中临床工作的完整性。我们在一所大学医院环境中通过开发 Tampere Research Archival System（TARAS）来解决这个问题，这是一个用于研究目的的广泛数据仓库。这个动态系统包括许多集成和化名的成像研究和临床数据。在一项哮喘患者的试点研究中，我们测试和改进了数据档案系统的功能。TARAS 可用于检索、分析和处理图像和非图像数据。在本文中，我们介绍了数据仓库实施过程的详细工作流程，特别关注行政、伦理、实际和数据安全问题。TARAS 的建立将增强和加速坦佩雷大学医院的研究实践，同时提高患者信息的安全性以及国家和国际研究合作的前景。我们希望从我们在大学医院规划、设计和实施结合成像研究和病历的研究数据仓库的经验中学到很多东西。
