The objective of this study was to assess impact of a report template quality improvement (QI) initiative on use of preferred phrases for communicating normal findings in structured abdominal CT and MRI reports. This prospective QI initiative, designed to decrease use of equivocal phrases and increase use of preferred and acceptable phrases (defined by multidisciplinary experts including patient advocates) in radiology reports, was performed in an academic medical center with over 800,000 annual radiologic examinations and was exempt from institutional review board approval. The intervention populated the preferred term "normal" (default) and acceptable specified pertinent negative phrases (pick-list option) when describing abdominal organ subheadings (liver, pancreas, spleen, adrenal glands, kidneys) within the "Findings" heading of abdominal CT and MRI report templates. We tabulated frequencies of the term "normal", specified pertinent negatives, and equivocal phrases in 21,629 reports before (June 1, 2017, to February 28, 2018) and 23,051 reports after (April 1, 2018, to December 31, 2018) the intervention using natural language processing and recorded trainee participation in report generation. We assessed intervention impact using statistical process control (SPC) charts and the Fisher exact test. Equivocal phrases were used less frequently in abdominal CT and MRI reports for both attending radiologists and trainees after the intervention ( < 0.05, SPC). Use of the term "normal" increased for reports generated by attending radiologists alone but decreased for reports created with trainee participation ( < 0.05, SPC). Frequency of pertinent negatives increased for reports with trainee participation ( < 0.05, SPC). A QI intervention decreased use of equivocal terms and increased use of preferred and acceptable phrases when communicating normal findings in abdominal CT and MRI reports.
本研究旨在评估报告模板质量改进(QI)计划对在结构腹部 CT 和 MRI 报告中使用描述正常发现的首选短语的影响。这项前瞻性 QI 计划旨在减少模棱两可的短语的使用,并增加在放射学报告中使用首选和可接受的短语(由包括患者代言人在内的多学科专家定义),在一家拥有超过 800,000 次年度放射学检查的学术医疗中心进行,并且免于机构审查委员会的批准。该干预措施在腹部 CT 和 MRI 报告模板的“发现”标题内描述腹部器官子标题(肝、胰腺、脾、肾上腺、肾)时,默认情况下使用首选术语“正常”(默认)和可接受的特定相关否定短语(选择列表选项)。我们使用自然语言处理技术,在干预前(2017 年 6 月 1 日至 2018 年 2 月 28 日)和干预后(2018 年 4 月 1 日至 2018 年 12 月 31 日)分别记录了 21629 份和 23051 份报告中术语“正常”、特定相关否定词和模棱两可短语的频率,并记录了学员参与报告生成的情况。我们使用统计过程控制(SPC)图表和 Fisher 精确检验评估干预措施的影响。干预后,主治放射科医生和学员在腹部 CT 和 MRI 报告中使用模棱两可的短语频率较低(<0.05,SPC)。仅由主治放射科医生生成的报告中“正常”一词的使用频率增加,但有学员参与的报告中则减少(<0.05,SPC)。有学员参与的报告中相关否定词的频率增加(<0.05,SPC)。QI 干预措施减少了在腹部 CT 和 MRI 报告中描述正常发现时使用模棱两可的术语,并增加了首选和可接受的短语的使用。
