A survey was conducted in the year 1994 among medical school hospitals
in Japan to know whether there are some written rules or regulations
about the use of medical information, and whether they are well matche
d both to secure patient's privacy and to promote the adequate use of
the information. A questionnaire was mailed to 80 medical school hospi
tals in Japan and 65 of them responded. Besides copies of rules, quest
ioners were also requested for detailed investigation. Twenty nine hos
pitals responded to our request. The security implementation issues in
Japan will be discussed using data thus obtained.
