To develop the checking system for prescription of injections by pharmacists,a questionnaire of intravenous admixture on nurses of 7 hospitals in Yamaguchi Prefecture was carried out.It became clear that nurses had many problems in the ward which is not clean.It seems dengerous for the nurses to mix many injections,because they must perform with various other works.The nurses strongly expected pharmacists admix injections.The information such as easily incompatible injections,adverse reaction for injections when those are administered, has been required.

In order to guarantee more effective and safer parenteral therapy for inpatients,the checking system for prescription of injections using personal computer were developed in Yamaguchi University Hospital. The system is formed by the following three components.(1) First checking system offers epitomized information of incompatibility,stability,administration routes and methods on the display of personal computer.(2) Second checking system offers the detailed information of each medication,if necessary,on the first checking system.(3) Message delivering system prints out information of stability and adverse reaction for doctors and nurses.We believe that the system has contributed to dispensing injections.
