RESUMEN
Anjo Kosei General Hospital is a large-scale hospital having 692 beds and located in the central part of Aichi. When the hospital moved into the present adress in April 2002, we introduced an electronic chart system that was not common in Japan at that time. Hospital management changed dramatically because until then we were using exclusively papers, and had not possessed even an electronic ordering system. It was also true in the field of medical office work. We hereby report the changes in routines after the introduction of the electronic chart system and its usefulness.The characteristics of our medical work system are as follows.(1)Data refrieval function (Data Ware House)(2)Credit control system(3)Receipt imaging functionWe are evaluating the various effects of the system from seven points of view as follows.(1)Basic data of medical care(2)Staff placement and personnel expenses(3)Work accuracy and efficiency(4)Patients service(5)Storage space reduction(6)Paper reduction(7)In-house questionnaire survey
