ABSTRACT
As a part of plan to construct a multifunctional hospital information system, We planned to develop a chemotherapy order system. First, a software developing team was established which is composed of hematooncology staffs, special pharmacists and programmer who are responsible for OCS. We set up an outline of this system after collecting various kinds of sources such as foreign examples, gathered protocol that are used for chemotherapy, and organized these protocol in programming the chemotherapy order system. This project is expected to provide accurate prescription, to shorten the time to prepare prescription, to standardize the protocol of chemotherapy within the medical center, to manage an effective dispensing schedule and to be used as a source for education and research.
