A study was performed to evaluate use of quality improvement techniques to decrease the variability in turnaround time (TAT) for radiology reports on emergency department (ED) radiographs. An interdepartmental improvement team applied multiple interventions. Statistical process control charts were used to evaluate for improvement in mean TAT for ED radiographs, percentage of ED radiographs read within 35 minutes, and standard deviation of the mean TAT. To determine if the changes in the radiology department had an effect on the ED, the average time from when an ED physician first met with the patient to the time when the final treatment decision was made was also measured. There was a significant improvement in mean TAT for ED radiographs (from 23.9 to 14.6 minutes), percentage of ED radiographs read within 35 minutes (from 82.2% to 92.9%), and standard deviation of the mean TAT (from 22.8 to 12.7). The mean time from when an ED physician first met with the patient to the time a final treatment decision was made decreased from 88.7 to 79.8 minutes. Quality improvement techniques were used to decrease mean TAT and the variability in TAT for ED radiographs. This change was associated with an improvement in ED throughput.
一项研究旨在评估质量改进技术的使用情况，以降低急诊科（ED）放射影像报告的周转时间（TAT）的变异性。一个跨部门的改进团队应用了多种干预措施。统计过程控制图用于评估 ED 放射影像的平均 TAT、35 分钟内阅读的 ED 放射影像百分比和平均 TAT 的标准差的改善情况。为了确定放射科的变化是否对 ED 有影响，还测量了 ED 医生首次与患者见面到最终治疗决策做出的时间的平均时间。ED 放射影像的平均 TAT（从 23.9 分钟降至 14.6 分钟）、35 分钟内阅读的 ED 放射影像百分比（从 82.2%提高至 92.9%）和平均 TAT 的标准差（从 22.8 分钟降至 12.7 分钟）均有显著改善。ED 医生首次与患者见面到最终治疗决策做出的时间的平均时间从 88.7 分钟降至 79.8 分钟。质量改进技术用于降低 ED 放射影像的平均 TAT 和 TAT 的变异性。这一变化与 ED 吞吐量的提高有关。
