Junior doctors routinely request radiological investigations for patients. Prior studies have noted that among this group there is a lack of knowledge on radiation legislation and radiation exposure in common radiological investigations. However, no studies have compared this against radiology trainees and radiographers. We compared knowledge of radiation legislation and radiation exposure in common radiological investigations among final year medical students (FYMS), foundation year doctors (FY1, FY2) against specialist radiology trainees (SRT) and radiographers (RG).
A 12-question multiple choice questionnaire (MCQ) was distributed to FYMS, FY1, FY2, SRT and RG at a UK teaching hospital. Questions assessed knowledge of radiation legislation and radiation-dose estimates of common radiological investigations. Mean MCQ scores were compared using one-way ANOVA and Tukey post-test to determine statistical significance (-value < 0.05).
127 participants were included in the study. Mean scores (%) for FYMS (49.3%), FY1 (52.6%) and FY2 (51.1%) were significantly lower compared to SRT (64.4%) and RG (66.3%) (-value < 0.05). Mean test scores between FYMS, FY1 and FY2 did not significantly differ (-value > 0.05).
FYMS, FY1 and FY2 knowledge of radiation legislation and radiation exposure in common radiological investigations was poor compared to SRT and RG. Patients require knowledge of radiation risk to provide informed consent as per IRMER regulations, thus we propose formal teaching on the subject matter to promote radiation safety culture among medical undergraduates and postgraduates.
First study to compare knowledge of radiation legislation and radiation exposure in common radiological investigations between medical students and junior doctors to radiology trainees and radiographers.
初级医生经常为患者申请放射学检查。先前的研究指出，在这一群体中，对辐射法规以及常见放射学检查中的辐射暴露缺乏了解。然而，尚无研究将其与放射科实习医生和放射技师进行比较。我们比较了医学本科最后一年学生（FYMS）、基础年医生（FY1、FY2）、专科放射科实习医生（SRT）和放射技师（RG）对辐射法规以及常见放射学检查中辐射暴露的了解情况。
在一家英国教学医院，向FYMS、FY1、FY2、SRT和RG发放了一份包含12个问题的多项选择题问卷（MCQ）。问题评估了辐射法规知识以及常见放射学检查的辐射剂量估计。使用单因素方差分析和Tukey事后检验比较平均MCQ分数，以确定统计学显著性（P值<0.05）。
127名参与者纳入了该研究。与SRT（64.4%）和RG（66.3%）相比，FYMS（49.3%）、FY1（52.6%）和FY2（51.1%）的平均分数（%）显著更低（P值<0.05）。FYMS、FY1和FY2之间的平均测试分数没有显著差异（P值>0.05）。
与SRT和RG相比，FYMS、FY1和FY2对辐射法规以及常见放射学检查中辐射暴露的了解较差。根据《电离辐射医学照射条例》（IRMER）的规定，患者需要了解辐射风险才能提供知情同意，因此我们建议就该主题进行正规教学，以促进医学本科生和研究生中的辐射安全文化。
第一项比较医学生和初级医生与放射科实习医生和放射技师在常见放射学检查中对辐射法规以及辐射暴露了解情况的研究。
