目的:本研究旨在分析国内外影像诊断和治疗的前景,专注于日本,为决策提供当前的见解,加强临床实践,和国际合作。
方法:1996年至2021年的数据来自日本卫生部,医疗设备CT的劳动和福利数据库,MRI,PET,乳房X线照相术,和放射治疗。日本的国家健康保险索赔和特定健康检查数据库用于检查编号。使用经济合作与发展组织(OECD)数据库对41个国家的数据进行了国际比较。
结果:数据包括总共108,596台CT设备,47,233MRI设备,2998PET装置,20,641MMG设备,和8023RT设备在调查期间。通过国际比较,日本每百万人的CT和MRI设备排名第一,每1000人的检查数量排名第二。每百万人的PET设备数量超过了经合组织的平均水平;然而,2020年,每1000人的考试数量低于经合组织的平均水平(日本:4.0,经合组织:4.9)。尽管日本的乳房X线摄影设备数量超过了经合组织的平均水平(日本:33.8,经合组织:2020年为24.5),放射治疗装置计数与OECD平均值相似(日本:8.3,OECD:7.9,2020年).
结论:我们分析了日本在影像诊断和放疗方面的设备使用情况。从最初的调查年开始,所有设备都呈上升趋势。然而,不仅必须增加设备和检查的数量,而且还必须解决放射科医生和专职卫生专业人员的长期短缺问题。基于从这项研究中获得的见解,了解诊断成像和放射治疗设备的实际状况对于掌握国内情况至关重要,并可能有助于提高日本的医疗保健质量。
OBJECTIVE: This study aimed to analyze the domestic and international landscape of imaging diagnostics and treatments, focusing on Japan, to provide current insights for policymaking, clinical practice enhancement, and international collaboration.
METHODS: Data from 1996 to 2021 were collected from Japan\'s Ministry of Health, Labor and Welfare database for medical device counts of CT, MRI, PET, mammography, and radiotherapy. The National Database of Health Insurance Claims and Specific Health Checkups of Japan was utilized for examination numbers. An international comparison was made with data from 41 countries using the Organization for Economic Cooperation and Development (OECD) database.
RESULTS: The data included a total of 108,596 CT devices, 47,233 MRI devices, 2998 PET devices, 20,641 MMG devices, and 8023 RT devices during the survey period. Upon international comparison, Japan ranked first in CT and MRI devices per million people and second in examination numbers per 1000 people. The number of PET devices per million people exceeded OECD averages; however, the number of examinations per 1000 people was below the OECD average in 2020 (Japan: 4.0, OECD: 4.9). Although Japan exceeded OECD averages in mammography device counts (Japan: 33.8, OECD: 24.5 in 2020), radiotherapy device counts were similar to OECD averages (Japan: 8.3, OECD: 7.9 in 2020).
CONCLUSIONS: We have analyzed the utilization of equipment in the context of diagnostic imaging and radiotherapy in Japan. Since the initial survey year, all devices have shown an upward trend. However, it is essential not only to increase the number of devices and examinations but also to address the chronic shortage of radiologists and allied health professionals. Based on the insights gained from this study, understanding the actual status of diagnostic imaging and radiation therapy equipment is critical for grasping the domestic situation and may contribute to improving the quality of healthcare in Japan.
