摘要:
目的:探讨运用PDCA(Plan, Do, Check, Action)循环降低直肠癌调强放疗摆位误差的效果。方法:对2016年10月~2020年10月于柳州市柳铁中心医院行直肠癌调强放疗的60例患者进行分析研究,针对摆位误差高的问题进行分析,将PDCA循环管理实施前、实施后摆位误差的情况进行对比。结果:实施前、后直肠癌调强放疗摆位误差,在X方向分别为(-1.389 4±0.426 7) mm、(-0.820 5±0.265 3) mm,Y方向为(0.971 2±0.296 1) mm、(0.421 3±0.111 4) mm,Z方向为(0.712 5±0.235 6) mm、(0.469 7±0.141 3) mm,差异有统计学意义(P<0.05)。结论:PDCA循环运用于降低直肠癌调强放疗摆位误差中的效果明显,可有效降低直肠癌调强放疗摆位的误差,从而最大限度地将剂量集中在肿瘤靶区内,减少肿瘤周围正常组织不必要的照射。
Abstract:
Abstract: Objective To investigate the effect of reducing set-up errors in intensity-modulated radiotherapy of rectal cancer by PDCA (Plan, Do, Check, Action) circulation. Methods Sixty rectal cancer patients who received intensity-modulated radiotherapy in Liuzhou Municipal Liutie Central Hospital from October 2016 to December 2020 were enrolled in the study. The reasons for large set-up errors are analyzed, and the set-up errors before and after the implementation of PDCA circulation were compared. Results There were statistical differences in set-up errors before and after the implementation of PDCA circulation which were (-1.389 4±0.426 7) mm and (-0.820 5±0.265 3) mm in X direction, (0.971 2±0.296 1) mm and (0.421 3±0.111 4) mm in Y direction, (0.712 5±0.235 6) mm and (0.469 7±0.141 3) mm in Z direction, respectively (P<0.05). Conclusion The application of PDCA circulation can effectively reduce the set-up errors in intensity-modulated radiotherapy of rectal cancer, thereby maximizing the dose concentration in the tumor target area and decreasing unnecessary irradiation of normal tissues around the tumor area.
