To study the impact of 24/7/365 attending radiologist coverage on the turnaround time (TAT) of trauma and nontrauma cases in an emergency and trauma radiology department.
This was a retrospective chart review in which TAT of patients coming to the emergency department between 2 periods: (1) December 1, 2012, to September 30, 2013, and (2) January 1, 2017, to January 30, 2018, and whose reports were read by an attending emergency and trauma radiologist was noted.
The 24/7/365 radiology coverage was associated with a significant reduction in TAT of computed tomography reports, and the time reduction was comparable between trauma and nontrauma cases. In adjusted models, the extension of radiology coverage was associated with an average of 7.83 hours reduction in overall TAT (95% confidence interval [CI]: 7.44-8.22) for reports related to trauma, in which 2.73 hours were due to reduction in completion to transcription time (TC; 95% CI: 2.53-2.93), and 5.10 hours were due to reduction in transcription to finalization time (TF; 95% CI: 4.75-5.44). For reports related to nontrauma cases, 24/7/365 coverage was associated with an average of 6.07 hours reduction in overall TAT (95% CI: 3.54-8.59), 2.91 hours reduction in TC (95% CI: 1.55-4.26), and 3.16 hours reduction in TF (95% CI: 0.90-5.42).
Our pilot study demonstrates that the implementation of on-site 24/7/365 attending emergency radiology coverage at a tertiary care center was associated with a reduced TAT for trauma and nontrauma patients imaging studies. Although the magnitude and precision of estimates were slightly higher for trauma cases as compared to nontrauma cases. Trauma examinations stand to benefit the most from 24/7/365 attending level radiology coverage.
研究急诊和创伤放射科 24/7/365 值班放射科医生覆盖对创伤和非创伤病例周转时间（TAT）的影响。
这是一项回顾性图表审查，记录了在两个时间段内来到急诊部的患者的 TAT：（1）2012 年 12 月 1 日至 2013 年 9 月 30 日，以及（2）2017 年 1 月 1 日至 2018 年 1 月 30 日，他们的报告由一名主治急诊和创伤放射科医生阅读。
24/7/365 放射科覆盖与 CT 报告的 TAT 显著缩短相关，且创伤和非创伤病例的时间缩短相当。在调整后的模型中，放射科覆盖范围的扩大与总体 TAT 平均缩短 7.83 小时（95%置信区间[CI]：7.44-8.22）相关，其中 2.73 小时归因于完成到转录时间（TC；95%CI：2.53-2.93）的缩短，5.10 小时归因于转录到完成时间（TF；95%CI：4.75-5.44）的缩短。对于与非创伤病例相关的报告，24/7/365 覆盖与总体 TAT 平均缩短 6.07 小时（95%CI：3.54-8.59）相关，TC 缩短 2.91 小时（95%CI：1.55-4.26），TF 缩短 3.16 小时（95%CI：0.90-5.42）。
我们的初步研究表明，在三级保健中心实施现场 24/7/365 值班急诊放射科医生覆盖与创伤和非创伤患者影像学研究的 TAT 缩短有关。尽管创伤病例的估计幅度和精度略高于非创伤病例，但创伤检查最受益于 24/7/365 值班放射科医生覆盖。
