PURPOSE/OBJECTIVE A national incentive brought about the instauration of systematic clinical audits of all Belgian radiotherapy departments (n = 25) from 2011 to 2015 using the International Atomic Energy Agency QUATRO (Quality Improvement Quality Assurance Team for Radiation Oncology) methodology. The impact of these audits was evaluated and the emitted recommendations originating from the audit reports were analysed to identify areas of weakness on a national basis. METHOD The QUATRO audits performed in each radiotherapy department gave rise to reports in which each department received a list of recommendations that it is free to implement. These audit reports were analyzed to identify common areas for which improvements were recommended. Moreover, questionnaires were sent to all departments in order to evaluate the overall usefulness of the recommendations as well as the relevancy and the actual impact of each individual recommendation. RESULTS Of the 381 emitted recommendations, 34% concerned process optimization of which a quarter involved process improvement and protocol development. Twenty-seven percent of the recommendations concerned infrastructure of which one-third was related to the quality of the equipment or facility. Nineteen and 20% of recommendations addressed department organisational and staff issues respectively. When analysing the departments' feedback questionnaires, 54% of the departments evaluated the audits' recommendations as being very useful. Furthermore, 42.7% of the recommendations were found to be very relevant and 23.5% were deemed to have an important impact. CONCLUSION This first round of audits in Belgium allowed for the identification of common areas for improvements of practice in radiation oncology departments, with a focus on process optimization and infrastructure elements. Similarly, the audits' emitted recommendations were globally deemed very relevant. Encouraged, by this analysis, a second cycle of audits has started in Belgium with a modified version of the QUATRO document (B-QUATRO).

放疗科室国家同行评审临床审计的可行性和影响

目的/目标 2011 年至 2015 年，一项国家激励措施使比利时所有放射治疗部门（n = 25）使用国际原子能机构 QUATRO（放射肿瘤学质量改进质量保证小组）方法恢复系统临床审计。对这些审计的影响进行了评估，并对源自审计报告的提出的建议进行了分析，以确定国家层面的薄弱环节。方法 在每个放射治疗部门进行的 QUATRO 审计产生了报告，其中每个部门都收到了一份可以免费实施的建议清单。对这些审计报告进行了分析，以确定建议改进的共同领域。而且，向所有部门发送了调查问卷，以评估建议的总体有用性以及每项建议的相关性和实际影响。结果 在提出的 381 条建议中，34% 涉及流程优化，其中四分之一涉及流程改进和协议开发。27% 的建议涉及基础设施，其中三分之一与设备或设施的质量有关。19% 和 20% 的建议分别涉及部门组织和人员问题。在分析部门的反馈问卷时，54%的部门认为审计的建议非常有用。此外，发现 42.7% 的建议非常相关，23. 5% 被认为具有重要影响。结论 比利时的第一轮审计确定了改进放射肿瘤科实践的共同领域，重点是流程优化和基础设施要素。同样，审计提出的建议在全球范围内被认为非常相关。在此分析的鼓舞下，比利时开始了第二轮审计，其中包含修改后的 QUATRO 文件 (B-QUATRO)。
