Research on the cost-effect relationship of imaging diagnostic modalities by using new medico-economic techniques

MRI和CT技术的显著发展提高了诊断的准确性，极大地改善了患者的健康状况。然而，这些新的诊断方式是昂贵的，并已部分负责医疗支出的增加。使用这些新的影像诊断模式所获得的好处和使用这些模式检查的病人的意愿并没有反映在关于医疗支出的辩论中。在我们以前的研究中进行的补助金，我们澄清，MRI在妇科疾病有一个很好的成本效益关系。在本研究中，通过概括疾病和分析方法进行评价。我们检查了卵巢癌和子宫体癌诊断的准确性，使用和不使用MRI，CT和对比增强，计算了包括检查费用在内的总医疗费用，并分析了成像方式的成本-效果关系， ...更多信息 每一种紊乱此外，还假设了一个假想的市场，通过询问受试者是否愿意为一种昂贵但安全、准确的检查或检查药物支付费用，来估计这种药物的附加价值。在卵巢癌和子宫体癌中，通过增加MRI和增强造影剂，可以提高诊断的准确性，减少总的医疗费用。另一方面，在宫颈癌中，建议增加MRI以减少总医疗费用，但增加造影剂会增加总医疗费用。接下来，通过假想市场法比较了安全但昂贵的非离子型造影剂和可能引起不良反应但便宜的离子型造影剂。因此，在本发明中，目前的药品价格差异在患者愿意接受的范围内，我们计划利用新的医学经济学技术，继续研究影像诊断方式的成本-效果关系，包括评估患者在放弃某项服务时愿意接受的最低金额（willingness-to-accept method）以及willingness-to-pay方法。少

Remarkable developments of MRI and CT techniques have led to improvements in the diagnostic accuracy and contributed greatly to the welfare of patients. However, these new diagnostic modalities are expensive and have been partly responsible for the increase in the medical expenditure. The benefit obtained by the use of these new imaging diagnostic modalities and the will of the patients examined by these modalities are not reflected in the debate concerning the medical expenditure. In our previous study conducted on a Grant-in-Aid, we clarified that MRI has an excellent cost-effect relation in gynecological disorders. in the present study, evaluation was made by generalizing the disease and analytical method. We examined the accuracy of the diagnoses of ovarian cancer and cancer of the uterine body with and without MRI, CT, and contrast enhancement, calculated the total medical cost including the cost for examinations, and analyzed the cost-effect relations of the imaging modalities in … More each disorder. Also, an imaginary market was postulated, and how much additional value there is to an expensive but safe and accurate examination or examination drug was estimated by asking the subjects about their willingness to pay for the benefit it provides.In ovarian cancer and cancer of the uterine body, the addition of MRI and the addition of a contrast enhancement were shown to improve the diagnostic accuracy and reduce the total medical expenditure. In cancer of the uterine cervix, on the other hand, the addition of MRI was suggested to reduce the total medical expenditure, but the addition of contrast enhancement increased it. Next, a safe but expensive non-ionic contrast medium and an ionic contrast medium, which is likely to cause adverse effects but is cheap, were compared by the imaginary market method. As a result, the present difference in the drug price was found to be within the range that patients are willing to tolerate as a cost for additional values.We are planning to continue our research on the cost-effect relationship of imaging diagnostic modalities by using new medico-economic techniques including the evaluation of the minimum amount of money that the patients are willing to accept when they give up a given service (willingness-to-accept method) as well as the willingness-to-pay method.
