In this multicentric survey, the management costs and the technical problems connected with the use of electron accelerators in Radiotherapy are studied. The data were collected by a proper questionnaire and concern 11/35 accelerators in use in Italy, in public hospitals, during the period 1982-1983. The average purchase cost of an accelerator was 1113 milions lire and the amortization cost is 111 milions lire per year. The expenses for the amortization of the cost of the bunker, for ordinary and extraordinary maintenance, for the employed staff and for the electric power respectively, represent the 22%, 5%, 43% and 2% of the total management cost (395 milions lire per year). In 1983 the load per machine was 400 patients and the cost per patient was 1 milion lire. On the average, 4 years are needed from the order to the beginning of the treatments with large differences among centers. The machines average use is 7.1 hours a day and keep 2.8 technicians busy per week. The time wasted by repairs or maintenances increases (+7%) the average duration of stay in hospital of patients. An attentive evaluation of the studied parameters allows us to single out the most significant variables on which is possible to work to increase the efficiency and to reduce the management costs of an accelerator.
在这项多中心调查中，研究了放射治疗中使用电子加速器的管理成本和技术问题。数据通过一份恰当的问卷收集，涉及1982 - 1983年期间意大利公立医院正在使用的35台加速器中的11台。一台加速器的平均购置成本为1.113亿里拉，摊销成本为每年1.11亿里拉。掩体成本摊销、普通和特别维护、所雇员工以及电力方面的费用分别占总管理成本（每年3.95亿里拉）的22%、5%、43%和2%。1983年每台机器的治疗量为400名患者，每名患者的成本为100万里拉。平均而言，从订购到开始治疗需要4年时间，各中心之间差异很大。这些机器平均每天使用7.1小时，每周使2.8名技术人员忙碌。因维修或维护而浪费的时间使患者平均住院时间增加了7%。对所研究参数的仔细评估使我们能够找出最显著的变量，针对这些变量努力提高效率并降低加速器的管理成本。
