Access to image interpretation in Ghana remains a challenge with the limited number of radiologists. Radiographers with the right skills and knowledge in image interpretation could help address this challenge. The aims of the study were to determine and compare the ability (accuracy, sensitivity and specificity) of radiographers and junior doctors in interpreting appendicular trauma radiographs both before and after training.
An action research study involving a pre and post training test was carried out to determine the level of accuracy, sensitivity and specificity in abnormality detection by radiographers after undergoing training when compared to junior doctors. Eight radiographers and twelve junior doctors were invited to interpret an image bank of 30 skeletal radiographs, both before and upon completion of an educational program. The participants' tests were scored against a reference standard provided by an experienced radiologist. Pre and post-test analysis were carried out for comparison.
Post training mean accuracy (radiographers 83.3% vs 68.8%, p = 0.017; doctors 81.9% vs 71.6%, p = 0.003), sensitivity (radiographers 83.3% vs 69.2%, p = 0.042; doctors 77.2% vs 67.8% p = 0.025) and specificity (radiographers 83.3% vs 68.3%, p = 0.011; doctors 86.7% vs 75.6% p = 0.005) of both groups significantly improved. No significant differences were recorded between the radiographers and doctors after the training event.
The study revealed that, with a well-structured training program, radiographers and junior doctors could improve on their accuracies in radiographic abnormality detection and commenting on trauma radiographs.
在加纳，由于放射科医生数量有限，图像解读服务的可及性仍然是一项挑战。具备图像解读所需适当技能和知识的放射技师有助于应对这一挑战。本研究的目的是确定并比较放射技师和初级医生在接受培训前后解读四肢创伤X光片的能力（准确性、敏感性和特异性）。
开展了一项行动研究，包括培训前和培训后的测试，以确定放射技师在接受培训后与初级医生相比在异常检测方面的准确性、敏感性和特异性水平。邀请了8名放射技师和12名初级医生在一个教育项目开始前和结束后解读包含30张骨骼X光片的图像库。根据一位经验丰富的放射科医生提供的参考标准对参与者的测试进行评分。进行培训前和培训后的分析以作比较。
培训后，两组的平均准确性（放射技师83.3%对68.8%，p = 0.017；医生组81.9%对71.6%，p = 0.003）、敏感性（放射技师83.3%对69.2%，p = 0.042；医生组77.2%对67.8%，p = 0.025）和特异性（放射技师83.3%对68.3%，p = 0.011；医生组86.7%对75.6%，p = 0.005）均显著提高。培训后，放射技师和医生之间未记录到显著差异。
该研究表明，通过精心设计的培训项目，放射技师和初级医生在X光片异常检测及创伤X光片评注方面的准确性能够得到提高。
