One of the important issues discussed in World Healthcare Organization (WHO), Europe and America is patient safety. Reducing medical errors is the primary goal to enhance patient safety. The bottleneck of the reduction is that the Hospital Information Systems (HIS) can not track the information about the patient's name, operational time and location immediately and correctly. Under such a situation, it is difficult to integrate the object flow and information flow so as to make systems analysis, decision support, and so on. After reviewing the literature and interviewing with experts, we find the most significant factor that results medical errors and serious hurt is the provision of medicine in inpatient healthcare. We fulfill the system analysis and design for the pharmaceutics operations in inpatient nursing. This system associated with RFID tags can automatically identify the patient identify, compare the drugs he takes and then synchronize the registration in the Electronic Healthcare Record(EHR). With this system, the mismatch, over-dosage, or drug--errors can be alerted and then eliminated. In addition, with the RFID tag, the modified flow of the standard of operation (SOP) to keep the drug safety can be more reliable.
