Abstract:
Objective:To explore the radiation protection awareness of pediatric CT chaperones and the guidance effects under different scenario modes.Methods:This study investigated 491 pediatric CT chaperones aged 24 to 63 who were treated in the Guangzhou Women and Children′s Medical Center from October 2023 to January 2024. These pediatric CT chaperones were guided to wear lead protective equipment, including a lead apron, neck shield, and cap, in the order of the self-pickup mode, single voice-sign language prompt mode, and multiple voice-sign language prompt mode. They were assigned 0.5 to 3 points/piece for each wearing, and their scoring result under different guidance modes were recorded. Moreover, the relationship of the scoring result with the age, gender, education, residence, and accompanying frequency was statistically analyzed.Results:In the self-pickup mode, the wearing accuracy rates of three kinds of protective equipment decreased in the order of the lead apron (31.57%, 155/491), lead cap (23.01%, 113/491), and lead neck shield (16.29%, 80/491). The number of pediatric CT chaperones wearing three kinds of protective equipment properly in the self-pickup mode represented 15.48% (76/491), including two first-time chaperones (2.63%, 2/76) and 74 chaperones experiencing two or more accompanying examinations (97.37%, 74/76). In the single prompt mode, the wearing accuracy rates of three kinds of protective equipment decreased in the order of the lead cap (71.89%, 353/491), lead apron (65.99%, 324/491), and lead neck shield (60.08%, 295/491). The proportion of accurate wearing of three kinds of protective equipment in the single prompt mode was 45.82% (225/491). In the multi-prompt mode, the wearing accuracy rates of three kinds of protective equipment decreased in the order of the lead neck shield (23.63%, 116/491), lead cap (5.09%, 25/491), and lead apron (2.44%, 12/491). Among all the pediatric CT chaperones, 38.70% (190/491) completed the accurate wearing of the three kinds of protective equipment until the multi-prompt mode.Conclusions:Pediatric CT chaperones typically show poor radiation protection awareness, necessitating the guidance of standardized voice-sign language prompts.
