To analyze and investigate the causes of radiation protection safety risks in nuclear medicine diagnosis and treatment, formulate radiation protection safety management countermeasures, and evaluate their effectiveness.
In October 2020, the Department of Nuclear Medicine at our hospital established a radiation protection safety management team, utilizing association rules to investigate and analyze the causes of radiation protection safety risks. A Wuli-Shili-Renli (WSR) system management approach was implemented, addressing physical (Wuli), procedural (Shili), and human factors (Renli) to improve technical safeguards, optimize processes, and enhance personnel awareness. A total of 1200 patients receiving diagnosis and treatment were divided into two groups. The control group (600 cases) used standard inspection-based radiation protection, while the observation group (600 cases) adopted WSR system management in addition to standard measures. Radiation protection risk control effectiveness and safety control capability scores were compared between the two groups.
The proportions of excessive diagnostic doses and additional radiation harm in the observation group were both lower than those in the control group (P < 0.05); the proportions of risk sources, including building environment, protective measures, dose monitoring, safety awareness, and waste disposal, in the observation group were all lower than those in the control group (P < 0.05). The observation group's scores in radiation protection theory, practical risk management skills, and radiation protection safety literacy, as well as the total score, were higher than those of the control group (P < 0.05).
The WSR system management approach effectively reduces radiation protection safety risks, improves the diagnostic and therapeutic environment, minimizes radiation exposure to patients and staff, and enhances safety risk management levels in nuclear medicine departments.
分析和调查核医学诊疗中辐射防护安全风险的原因，制定辐射防护安全管理对策并评估其效果。
2020年10月，我院核医学科成立辐射防护安全管理小组，利用关联规则调查分析辐射防护安全风险的原因。实施物理（物）、程序（事）、人员（人）相结合的WSR系统管理方法，以改进技术保障、优化流程并提高人员意识。将1200例接受诊疗的患者分为两组。对照组（600例）采用基于标准检查的辐射防护，观察组（600例）除标准措施外还采用WSR系统管理。比较两组的辐射防护风险控制效果和安全控制能力得分。
观察组诊断剂量超标及额外辐射伤害的比例均低于对照组（P<0.05）；观察组在建筑环境、防护措施、剂量监测、安全意识、废物处理等风险源方面的比例均低于对照组（P<0.05）。观察组在辐射防护理论、实际风险管理技能、辐射防护安全素养以及总分方面的得分均高于对照组（P<0.05）。
WSR系统管理方法有效降低了辐射防护安全风险，改善了诊疗环境，减少了患者和工作人员的辐射暴露，并提高了核医学科的安全风险管理水平。
