■提高严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)RNA标本的检测能力和效率对于预防和控制2019年冠状病毒病(COVID-19)的爆发非常重要。在这项研究中,我们评估了2022年4月和7月流程重组前后两次COVID-19暴发的检测能力和效率.
■这项回顾性横断面研究涉及359,845例SARS-CoV-2RNA标本,这些标本在4月和7月两次COVID-19爆发前2周和2周后。数字,标本的运输时间和检测时间,采用SPSS软件对24h以上的报告数进行分析。
■虽然16.84%的人选择了鼻咽拭子(NPS)标本,83.16%选择口咽拭子(OPS)标本检测SARS-CoV-2RNA。从过程重新设计前的4月到过程重新设计后的7月,10个样本合并(P-10)的百分比呈显着上升趋势(p<0.001)。与四月相比,7月标本数量不仅在COVID-19爆发前2周,而且在爆发后2周也显着增加,分别增加了35.46和93.94%,分别。在重新设计流程之后,7月COVID-19爆发前后2周超过24小时的报告数量明显低于流程重新设计前的4月(0%vs.0.06%和0vs.0.89%,两者p<0.001)。
■本研究表明,加强多部门在流程再造中的合作,特别是使用P-10策略和全过程信息化可以提高SARS-CoV-2RNA标本的检测能力和效率。
Improving the detection capability and efficiency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA specimens is very important for the prevention and control of the outbreak of Coronavirus disease 2019 (COVID-19). In this study, we evaluated the detection capability and efficiency of two outbreaks of COVID-19 before and after the process re-engineering in April and July 2022.
This retrospective cross-sectional study involved 359,845 SARS-CoV-2 RNA specimens 2 weeks before and 2 weeks after the two outbreaks of COVID-19 in April and July. The number, transportation time and detection time of specimens, and the number of reports of more than 24 h were analyzed by SPSS software.
While 16.84% of people chose nasopharyngeal swabs (NPS) specimens, 83.16% chose oropharyngeal swabs (OPS) specimens to detect SARS-CoV-2 RNA. There were significant upward trends in the percentage of 10 sample pooling (P-10) from April before process re-engineering to July after process re-engineering (p < 0.001). Compared with April, the number of specimens in July increased significantly not only 2 weeks before but also 2 weeks after the outbreak of COVID-19, with an increase of 35.46 and 93.94%, respectively. After the process re-engineering, the number of reports more than 24 h in the 2 weeks before and after the outbreak of COVID-19 in July was significantly lower than that in April before process re-engineering (0% vs. 0.06% and 0 vs. 0.89%, both p < 0.001).
The present study shows that strengthening the cooperation of multi-departments in process re-engineering, especially using the P-10 strategy and whole process informatization can improve the detection capability and efficiency of SARS-CoV-2 RNA specimens.
