To determine the prevalence and determinants of radiologic imaging requests that are of inadequate quality according to the Reason for exam Imaging Reporting and Data System (RI-RADS).
This study included a random sample of 673 radiologic examinations performed at a tertiary care center. The quality of each imaging request was graded according to RI-RADS. Ordinal regression analysis was performed to determine the association of RI-RADS grade with patient age, gender, and hospital status, indication for imaging, requesting specialty, imaging modality, body region, time of examination, and relationship with previous imaging within the past one year.
RI-RADS grades A (adequate request), B (barely adequate request), C (considerably limited request), and D (deficient request) were assigned to 159 (23.6 %), 166 (24.7 %), 214 (31.8 %), and 134 (19.9 %) of cases, respectively. Indication for imaging, requesting specialty, and body region were independently significantly associated with RI-RADS grades. Specifically, routine preoperative imaging (odds ratio [OR]: 3.422, P = 0.030) and transplantation imaging requests (OR: 8.710, P = 0.000) had a higher risk of poorer RI-RADS grades, whereas infection/inflammation as indication for imaging (OR: 0.411, P = 0.002), pediatrics as requesting specialty (OR: 0.400, P = 0.007), and head (OR: 0.384, P = 0.017), spine (OR: 0.346, P = 0.016), and upper extremity (OR: 0.208, P = 0.000) as body regions had a lower risk of poorer RI-RADS grades.
The quality of radiologic imaging requests is inadequate in >75 % of cases, and is affected by several factors. The data from this study can be used as a baseline and benchmark for further investigation and improvement.
根据检查原因影像学报告和数据系统（RI-RADS）确定质量不足的放射影像学检查申请的发生率和决定因素。
本研究纳入了一家三级保健中心进行的随机抽样 673 例放射学检查。根据 RI-RADS 对每个影像学申请的质量进行分级。采用有序回归分析确定 RI-RADS 分级与患者年龄、性别和医院状况、影像学检查指征、申请科室、影像学方式、身体部位、检查时间以及与过去一年中之前影像学检查的关系之间的关联。
分别将 RI-RADS 分级 A（充分的申请）、B（勉强充分的申请）、C（相当有限的申请）和 D（不足的申请）分配给 159 例（23.6%）、166 例（24.7%）、214 例（31.8%）和 134 例（19.9%）的病例。影像学检查指征、申请科室和身体部位与 RI-RADS 分级独立显著相关。具体而言，常规术前影像学检查（比值比 [OR]：3.422，P=0.030）和移植影像学检查申请（OR：8.710，P=0.000）具有较差的 RI-RADS 分级风险较高，而感染/炎症作为影像学检查指征（OR：0.411，P=0.002）、儿科作为申请科室（OR：0.400，P=0.007）、头部（OR：0.384，P=0.017）、脊柱（OR：0.346，P=0.016）和上肢（OR：0.208，P=0.000）作为身体部位具有较低的较差 RI-RADS 分级风险。
放射影像学检查申请的质量不足>75%，且受多种因素影响。本研究的数据可用作进一步调查和改进的基线和基准。
