The College of Radiographers has called for 'Red Dot' schemes to evolve and has recommended the development of radiographer commenting. The implementation of a radiographer comment scheme assumes that radiographers previously participating in 'red dot' schemes have been accurately recognising radiographic abnormalities and are, therefore, able to comment upon, and describe, such radiographic appearances. Research evidence to support such an assumption is sparse. This study compares the ability of radiographers attending a short course on musculoskeletal trauma to 'red dot' and comment on A&E radiographic appearances.
This study adopted a pre-test, post-test approach. One hundred and twenty one radiographers attending a short course on musculoskeletal trauma (Bradford Red Dot Course) were invited to undertake an assessment of their ability to recognise ('red dot') and describe (comment upon) radiographic abnormalities at the start and end of the short course.
One hundred and fifteen radiographers (n=115/121; 95.0%) completed both the pre- and post-training assessments. Post-training mean scores per case improved on average by 9.8% [p=0.012; 95% CI: 2.4, 17.1] for 'red dots' and 12.7% [p=0.007; 95% CI: 3.8, 21.5] for commenting. However, the difference between mean 'red dot' and commenting scores remained similar with mean radiographer comment scores being 13.7% less than mean 'red dot' scores pre-training and 10.8% less post-training.
The results of this study indicate that the accuracy of radiographer comments was significantly reduced when compared to the accuracy of 'red dots' for the same radiographic images. The clinical significance of these findings for departments wanting to move from a 'red dot' system to a radiographer commenting scheme is that without appropriate training and audit, the quality of service and assistance to the A&E department could be significantly reduced.
放射技师学院呼吁“红点”计划不断发展,并建议开展放射技师评注工作。实施放射技师评注计划的前提是,之前参与“红点”计划的放射技师能够准确识别放射影像异常,因此能够对这些放射影像表现进行评注和描述。但支持这一假设的研究证据很少。本研究比较了参加肌肉骨骼创伤短期课程的放射技师对急症室放射影像进行“红点”标注和评注的能力。
本研究采用前测、后测的方法。邀请121名参加肌肉骨骼创伤短期课程(布拉德福德红点课程)的放射技师,在短期课程开始和结束时评估他们识别(“红点”标注)和描述(评注)放射影像异常的能力。
115名放射技师(n = 115/121;95.0%)完成了培训前和培训后的评估。培训后,每个病例的“红点”标注平均得分提高了9.8%[p = 0.012;95%可信区间:2.4,17.1],评注平均得分提高了12.7%[p = 0.007;95%可信区间:3.8,21.5]。然而,“红点”标注平均得分与评注平均得分之间的差异仍然相似,放射技师评注平均得分在培训前比“红点”标注平均得分低13.7%,培训后低10.8%。
本研究结果表明,对于相同的放射影像,与“红点”标注的准确性相比,放射技师评注的准确性显著降低。对于希望从“红点”系统转向放射技师评注计划的科室来说,这些发现的临床意义在于,如果没有适当的培训和审核,急症室的服务质量和得到的协助可能会显著降低。
