Abstract
To standardize and develop a convenient inputting method for prescriptions, the frequency and directions of use were examined in an ordering system. A total of 552 kinds of directions have so far been registered on our system. However, 250 derections (45%) had not been used for 1 month. The probability of selecting some directions on the first guide screen was analyzed. Of the drugs used, 95% of internal and 96% of external drugs could be prescribed on the first guide screen. The directions consisted of words and phrases, and these were classified into 4 types of information, how to use, how many times, when and where to use the medication. Based on our results, we also evaluated the inputting method.
