Recently Health Information Exchange (HIE) is gradually spreading in Japan. But there are few reports about the effect of the hospital management. So we examined the effect for hospital management through the number of the newly admitted patients from 2013 to 2017. In this study both the total number of the admitted patients who was reserved as first visit patients was higher than not reserved and the number of the admitted patients who visited with introduction letters was higher than without introduction letters. (p < 0.01) The total number of the admitted patients who had been registered to the Ajisai-net was 624 (41.2%) for the same 5 years, and was revealed to be significantly higher than the number of the admitted patients who was reserved first visit with introduction letters. (p < 0.01) In conclusion, use of the Japanese type of the HIE has a potential to increase the newly admitted patients finally.
