Abstract:: Abstract: Objective To explore the effect of playful situational intervention on the positioning accuracy in radiotherapy for children. Methods Children who received radiotherapy in Sun Yat-sen University Center Cancer from March 2020 to May 2022 were enrolled in the study. The patients in experimental group (n=24) were given playful situational intervention before radiotherapy, and the radiotherapy was carried out after psychological adjustment. Those in control group (n=21) received radiotherapy after routine preparation.?he positioning accuracy in radiotherapy was compared between two groups. Results The setup errors in left-right (LR), superior-inferior (SI) and anterior-posterior (AP) directions were (-0.32±2.18), (-0.12±2.24), (-0.17±2.32) mm in experimental group, and (-0.93±1.91), (0.79±1.75), (-0.63±1.97) mm in control group. There were significant differences in setup errors between two groups in LR and SI directions (LR: t=2.28, P=0.02 SI: t=-2.58, P=0.01), but not in AP direction (t=1.63, P=0.11). Conclusion Playful situational intervention can improve patient compliance, thereby improving the positioning accuracy of radiotherapy, with significant clinical significance and popularization value.
