医療経済学から見た粒子線治療 Particle radiation therapy from the viewpoint of medical economics
First, features of particle radiation therapy from the viewpoint of medical economics are pointed out. Then, relationship between effectiveness of particle radiation therapy and (time distance)cost is figured out, being expressed by a function, y=f(x). At the same plane of x-y coodinates, y=g(x) is defined to express relationship between urgent necessity x of particle radiotherapy for a patient and the capability of accepting such urgent necessity. The method of looking for the cross point by placing y=f(x)=g(x) in order to find economical significance of particle radiation therapy, and for the possibility of building up new facilities for the particle radiation therapy where and when and by what cost, are discussed. Moreover, the problems of non-profitable actions, redemption of generated cost and investment, and calculation of cost-effectiveness are raised.<BR>Especially, method of cost-effective analysis is proposed, and conclete proccedure for the measurement of cost, especially human cost which is considered to be very difficult to measure is presented. The method is according to the time study of medical stuffes for a certain patient. The experience of the author to carry out such study is reflected.<BR>Lastly, the advantage of constructing a databese for cost-effectiveness analysis and accumulation of measured data is stated.
