To determine the accuracy of radiographer plain radiograph reporting in clinical practice.
Studies were identified from electronic sources and by hand searching journals, personal communication and checking reference lists. Eligible studies assessed radiographers' plain radiograph reporting in clinical practice compared with a reference standard, and provided accuracy data to construct 2 x 2 contingency tables. Data were extracted on study eligibility and characteristics, quality and accuracy. Summary estimates of sensitivity and specificity and receiver operating characteristic curves were used to pool the accuracy data.
Radiographers compared with a reference standard, report plain radiographs in clinical practice at 92.6% (95% CI: 92.0-93.2) and 97.7% (95% CI: 97.5-97.9) sensitivity and specificity, respectively. Studies that compared selectively trained radiographers and radiologists of varying seniority against a reference standard showed no evidence of a difference between radiographer and radiologist reporting accuracy of accident and emergency plain radiographs. Selectively trained radiographers were also found to report such radiographs as accurately as those not solely from accident and emergency, although some variation in reporting accuracy was found for different body areas. Training radiographers improved their accuracy when reporting normal radiographs.
This study systematically synthesizes the literature to provide an evidence-base showing that radiographers can accurately report plain radiographs in clinical practice.
确定临床实践中放射技师平片报告的准确性。
通过电子资源、手工检索期刊、个人交流以及查阅参考文献列表来识别研究。符合条件的研究评估了临床实践中放射技师的平片报告,并与参考标准进行比较,同时提供准确性数据以构建2×2列联表。提取了关于研究合格性和特征、质量及准确性的数据。使用敏感性和特异性的汇总估计值以及受试者工作特征曲线来汇总准确性数据。
与参考标准相比,放射技师在临床实践中报告平片的敏感性分别为92.6%(95%置信区间:92.0 - 93.2),特异性分别为97.7%(95%置信区间:97.5 - 97.9)。将经过选择性培训的放射技师和不同资历的放射科医生与参考标准进行比较的研究表明,在事故和急诊平片报告准确性方面,放射技师和放射科医生之间没有差异的证据。还发现经过选择性培训的放射技师报告此类平片的准确性与非仅来自事故和急诊的放射技师相同,尽管不同身体部位的报告准确性存在一些差异。培训放射技师在报告正常平片时提高了他们的准确性。
本研究系统地综合了文献,以提供证据表明放射技师在临床实践中能够准确报告平片。
