The aim of this study was to perform an operational improvement project targeted at the breast imaging reading workflow of mammography examinations at an academic medical center with its associated breast centers and satellite sites. Through careful analysis of the current workflow, two major issues were identified: stockpiling of paperwork and multiple worklists. Both issues were considered to cause significant delays to the start of interpreting screening mammograms. Four workflow changes were suggested (scanning of paperwork, worklist consolidation, use of chat functionality, and tracking of case distribution among trainees) and implemented in July 2015. Timestamp data was collected 2 months before (May-Jun) and after (Aug-Sep) the implemented changes. Generalized linear models were used to analyze the data. The results showed significant improvements for the interpretation of screening mammograms. The average time elapsed for time to open a case reduced from 70 to 28 min (60 % decrease, p < 0.001), report turn-around time with preliminary signature decreased from 151 to 107 min (29 % decrease, p < 0.001), and report turn-around time final signature from 153 to 139 min (9 % decrease, p = 0.002). These improvements were achieved while keeping the efficiency of the workflow for diagnostic mammograms at large unaltered even with increased volume of mammography examinations (31 % increase of 4344 examinations for May-Jun to 5678 examinations for Aug-Sep). In conclusion, targeted efforts to improve the breast imaging reading workflow for screening mammograms in a teaching environment provided significant performance improvements without affecting the workflow of diagnostic mammograms.
本研究的目的是在一所学术医疗中心及其相关乳腺中心和卫星站点开展一项针对乳腺钼靶检查乳腺影像阅片流程的运营改进项目。通过对当前流程的仔细分析,确定了两个主要问题:文书工作积压和多个工作清单。这两个问题均被认为会导致筛查乳腺钼靶影像解读工作的起始出现显著延迟。提出了四项流程改进措施(文书扫描、工作清单整合、使用聊天功能以及跟踪实习生之间的病例分配)并于2015年7月实施。在实施改进措施之前(5 - 6月)和之后(8 - 9月)的2个月收集了时间戳数据。使用广义线性模型对数据进行分析。结果显示筛查乳腺钼靶影像解读有显著改善。打开病例的平均用时从70分钟减少至28分钟(减少60%,p < 0.001),带有初步签名的报告周转时间从151分钟减少至107分钟(减少29%,p < 0.001),最终签名的报告周转时间从153分钟减少至139分钟(减少9%,p = 0.002)。即使乳腺钼靶检查量增加(从5 - 6月的4344次检查增加31%至8 - 9月的5678次检查),在保持诊断性乳腺钼靶影像流程效率大体不变的情况下实现了这些改进。总之,在教学环境中针对筛查乳腺钼靶影像阅片流程进行的有针对性改进显著提高了工作绩效,且未影响诊断性乳腺钼靶影像的流程。
