In this paper, the new method to support the communication between doctors and patients using computers is proposed. The method is aimed at visualization of topic structure to contribute to "narrative-based medicine(NBM)". NBM becomes emphasized in the clinical medicine. The dialogue between a doctor and a patient is segmented into blocks, the text objects. Correlations between each text object are calculated using the numbers of common words in text objects. The dialogue is visualized by drawing lines of the thickness according to strength of correlation between text objects. The methods were applied to two dialogues. One of them was introduce as proper, and the other was inappropriate. It was naturally thought that there were patters of lines between text objects in each step in NBM. In the former dialogue, it was observed that the patterns which appear when NBM was practiced appropriately. While the patterns was not observed in the latter one. As a result, the effectiveness of the proposed method was confirmed.

This survey showed differences in how medical information is perceived by consumers and hospital administrators (chief administrators and managers). The same questions were asked of consumers and hospitals. The consumer subjects of the survey were normal males and females 15 to 65 years old living within a radius of 30 km of central Tokyo. The extraction method was a survey questionnaire, which was made available to visiting survey staff, and comprised a layered two-tier extraction from the public resident registry. A total of 1665 subjects participated during the survey period from June 28 to July 11, 2001. Questionnaires distributed to hospitals represented how they imagined patients perceived medical information. Survey subjects were chief administrators and managers of member hospitals of the Japan Hospital Association (2621 facilities). The survey method was an anonymous questionnaire mailed to 2621 facilities (two per facility) on October 18, 2001. Significant differences in perception were found in the inadequacy of medical information and methods of providing medical information.

Healthcare is in a area of service from the standpoint of marketing. However, medical service has several points that distinguish themselves from other services.

In this paper, how to adapt marketing to medical service is investigated. Then, differentiationstrategy is emphasized.

広告や情報提供は、消費者の必要に対応しなければならない。しかしながら、消費者や患者がどんな情報を必要としているか、という調査は少ない。今回われわれは消費者に対して、医療情報についてのアンケート調査を実施したので報告する。<BR>信頼できる情報源について「第三者機関」を望む意見が大きかった。これは、消費者が客観的な評価を期待していることの現れであろう。たとえば、日本では1995年から日本医療機能評価機構が医療機能評価をはじめているが、認定を受けた病院数が日本の全病院の1割にも満たない状況である。<BR>また希望する医療情報提供については、医療機関からの情報を望むものが圧倒的多く、医療機関の広告・広報活動に対する期待の大きさを裏付けた。日本でも医療機関の広告規制緩和は徐々に進みつつある。しかし、一方で広告は、無駄な医療需要を作り出す恐れもある。適切な広告規制緩和が望まれる。

<p> Objective: The Internet literacy of Japanese medical doctors (MDs) is investigated in this study.</p><p> Subjects and Methods: A survey was made by mail to 60,000 medical doctors in Japan. The number of respondents was 14,105 (response rate 23.5%).</p><p> Results: The ratio of medical doctors having PCs was relatively high. The access to Internet was not good as the MD was elder. The access place of salaried physician for Internet was 50 : 50 between at home and at workplace, and that of self-employed physician was higher at home than at workplace. MDs obtain medical information through Internet by 80%. Interactive communication between MDs and patients was done by 20%.</p>

<p> Recently, the consumer's consciousness to health care is increasing in Japan. The Ministry of Health, Labor and Welfare did the deregulation in terms of advertisement in health care in March 1st, 2001. On the other hand, the legal help, such as Health Insurance Portability and Accountability Act (HIPAA), has built in 1996 in the US. For example, the American people join in clinical trials easily. It is not only due to their volunteer spirits but also the literacy and infrastructure for healthcare information. The infrastructure for the consumers to get the correct health information should be built in Japan like that in the US.</p>
