the reserved first visit bringing the introduction letters, 2nd type is the non-reserved first visit bringing the introduction letters 
and 3rd type is non-reserved first visit not bringing the introduction letters. The total number of hospitalized patients was 
12,237/32,398 (37.8%) on the first type, 8,764/ 24,549 (35.7%) on the second type and 1,277/7,167 (17.8%) on the third type, 
and there were significantly differences among 3 types. (p<0.01) The number of hospitalized patients of the reserved new 
patients bringing the introduction letters who had been registered to the Ajisai-net was 1,008/2,201(45.8%), significantly more 
than the number of hospitalized patients of any other 3 types of the first visit patients. (p<0.01)

of the high hospital income in Japan. In conclusion, Japanese type of HIE has a positive effect of the Hospital management
