目前各地区不同级别的放疗单位中,临床治疗流程、人员资质和结构、设备的配置和状态、质控水平尚不统一,多数省级质控中心尚无可量化、客观化的质量安全评价标准进行放疗质量安全和质控水平的评价。这影响了省级质控中心对本省放疗单位的质控管理、质量安全和质控水平进行检查、监督和评价,也影响国家肿瘤质控中心对全国放疗单位质控水平进行同质化评估。鉴于此,本指南系统介绍肿瘤放射治疗质量安全的评价项目、评价要点、检查要素和评价对象等内容,以期建立适用各级放疗单位的放疗质量安全评价标准体系,搭建同质化平台,以解决当前不同省份、不同级别的医院质量保证难以监控的实际问题,为各级放疗质控中心的质控评价和质量安全管理提供统一的、有效的评价标准。
