隨著資訊科技快速的發展，傳統紙張的醫療記錄已逐漸改為電子格式。許多醫療機構已經開始利用資訊技術來控制醫療成本，促進醫療服務效率和質量，並投入大量人力和預算發展多樣化的醫療資訊系統，像是電子病歷，影像儲存系統及護理資訊系統。然而，為了節省醫療資源，希望讓病患的醫療資訊能共享到其它醫療院所並享有安全的環境，但在不同的醫療機構會使用不同的系統，因此在格式上面當然也就不同。在本研究中，並不會大幅度的改變當前醫療資訊系統也不會增加高額的成本，藉著虛擬式整合醫療資訊系統（VIMS）會協助各醫院在資訊的交流，此外透過行動代理人可以安全的收集分散在各個醫療機構的病歷資料。虛擬式整合醫療資訊系統（VIMS）是一個虛擬的電子整合系統並結合行動代理人技術。行動代理人擁有獨立性，適應性強和自主性，可克服來自於異質性系統的問題。另外，行動代理人可以確保即時性和實用性，從醫療記錄，醫生可以作出最適當的評估與診斷。該系統不僅可以提高醫療護理質量，這將可避免醫療資源的浪費，如重複用藥等，而可進一步成為參考諮詢或健康檢查的參考。

With the rapid development of information technology, paper-based medical records have gradually been changed to electronic forms. A lot of medical organizations have started to utilize information technology to promote service efficiency and medical quality that they have started to invest manpower and budget in developing diverse medical information systems, such as Electronic Patient Record, Nursing Information System. Nevertheless, different systems or medical organizations present individual system specifications and data-saving formats so that the medical information of the same patient cannot be exchanged, shared, and securely accessed. In order not to largely change the present medical information systems as well as not to increase abundant costs, Virtual Integrated Medical-information Systems (VIMS) is proposed to assist various hospitals in information exchange. Furthermore, with Mobile Agent, the dispersed medical information can be securely integrated. It presents confidentiality, non-repudiation, source authentication, and integrity in network transmission. Virtual Integrated Medical-information Systems (VIMS) is a virtual electronic integration system combined with Mobile Agent technology. With the features of independence, adaptability, mobility, objectives, and autonomy, Mobile Agent is applied to overcome the problems from heterogeneous systems. With the features, the over-dispersed medical records can be integrated. Moreover, Mobile Agent can ensure the instantaneity and usability of medical records from which doctors can make the most appropriate evaluation and diagnoses. It will avoid the waste of medical resources.
