The purpose of this study was to investigate the status of remote-radiotherapy treatment planning (RRTP) in Japan through a nationwide questionnaire survey. The survey was conducted between 29 June and 4 August 2022, at 834 facilities in Japan that were equipped with linear accelerators. The survey utilized a Google form that comprised 96 questions on facility information, information about the respondent, utilization of RRTP between facilities, usage for telework and the inclination to implement RRTPs in the respondent's facility. The survey analyzed the utilization of the RRTP system in four distinct implementation types: (i) utilization as a supportive facility, (ii) utilization as a treatment facility, (iii) utilization as a teleworker outside of the facility and (iv) utilization as a teleworker within the facility. The survey response rate was 58.4% (487 facilities responded). Among the facilities that responded, 10% (51 facilities) were implementing RRTP. 13 served as supportive facilities, 23 as treatment facilities, 17 as teleworkers outside of the facility and 5 as teleworkers within the facility. In terms of system usage between supportive and treatment facilities, 70-80% of the participants utilized the system for emergencies or as overtime work for external workers. A substantial number of facilities (38.8%) reported that they were unfamiliar with RRTP implementation. The survey showed that RRTP utilization in Japan is still limited, with a significant number of facilities unfamiliar with the technology. The study highlights the need for greater understanding and education about RRTP and financial funds of economical compensation.

日本远程放射治疗计划的现状：全国调查结果†。

本研究的目的是通过全国范围的问卷调查来调查日本远程放射治疗计划（RRTP）的现状。该调查于2022年6月29日至8月4日期间在日本834个配备直线加速器的设施中进行。该调查使用了 Google 表格，其中包含 96 个问题，涉及设施信息、受访者信息、设施之间 RRTP 的使用情况、远程办公的使用情况以及受访者设施中实施 RRTP 的倾向。该调查分析了 RRTP 系统在四种不同实施类型中的使用情况：(i) 作为支持设施使用，(ii) 作为治疗设施使用，(iii) 作为设施外的远程工作人员使用，以及 (iv) 作为设施外的远程工作人员使用。设施内的远程工作人员。调查回复率为 58.4%（487 家机构回复）。在做出回应的机构中，10%（51 家机构）正在实施 RRTP。13 个作为支持设施，23 个作为治疗设施，17 个作为设施外的远程工作人员，5 个作为设施内的远程工作人员。在支持设施和治疗设施之间的系统使用方面，70-80%的参与者将系统用于紧急情况或外部工人的加班工作。大量机构 (38.8%) 表示不熟悉 RRTP 的实施。调查显示，RRTP 在日本的使用仍然有限，大量设施不熟悉该技术。该研究强调需要加强对RRTP和经济补偿资金的了解和教育。
