ABSTRACT
Here we report the results of a long-term analytical study on the utilization of antihypertensive and antibacterial agents, which was performed using the Integrated Medical Information System (IMIS) developed by Kochi Medical School. The results indicate clear (increasing or decreasing) patterns in the numbers of patients and the dosages. Specifically, the total amount of antibacterials recently prescribed is significantly lower than in the year analysis began (1983). This reduction provides evidence of a steady improvement in the quality of medication and is particularly important for macrocosmic evaluation of the primary focus of our study, which was the “proper use of drugs”. Furthermore, the results also showed medication prescribed by non-specialists to be less inventive than that prescribed by specialists. This study highlights the importance of reforming institutions providing medical treatment from the perspective of effectively utilizing medical resources (by employing specialist personnel) and the proper use of medications. Because non-specialists prescribe medication in numerous medical facilities throughout Japan, these issues must be seriously considered.
