Abstract：
Background: A sampling platform (or table) set at the patient\'s side in a zero-exposure screening center (booth) might be used for specimen collection during public health crises such as the COVID-19 pandemic. However, repeated sanitization causes moisture problems. Such moisture problems would not only be noted by patients but also interrupt the sampling process. In this study, we aimed to develop 3D-printed mesh-covered fluid collecting racks (MFCRs) to address surface moisture problems to determine whether MFCRs can shorten the sampling time. Methods: This was an observational, descriptive, and cross-sectional study. We observed the reasons for sampling interruptions related to surface moisture problems among patients who used MFCRs or did not (April 28-30, 2022). We used a 3D printer to make an MFCR, which measured 14.5 cm in width and length and 1.0 cm in height. The MFCR allows the ethanol to drain through the mesh into the fluid collection rack below to leave a relatively dry surface on the mesh. Finally, we calculated the median time to finish sampling between MFCRs and non-MFCRs. Results: A total of 400 patients were randomly observed (using MFCRs, n = 200; non-MFCRs, n = 200). Patients in the non-MFCR group were more likely to interrupt the sampling process (n = 39, 19.5%) by noting surface moisture problems than those in the MFCR group (n = 3, 1.5%). Two of the major interruptions, \"asking questions about the moist surface\" (from 12% to 1%) and \"slowing down their actions\" (from 4.5% to 0.5%), were obviously improved by using MFCRs. Overall, the median sampling time was significantly shorter (p < 0.001) in the group using MFCRs (0.6 min) than in the group using non-MFCRs (1.5 min). The MFCRs shortened the sampling time by 60%, which might be associated with decreasing interruptions caused by surface moisture problems. Conclusions: The 3D printed MFCRs are suitable for handling surface moisture problems caused by repeated sanitizations. More importantly, the MFCRs might be associated with decreasing interruptions caused by moisture problems.
摘要：
背景：在零暴露筛查中心（展位）设置在患者一侧的采样平台（或工作台）可用于在诸如COVID-19大流行之类的公共卫生危机期间进行标本收集。然而,反复消毒会导致水分问题。这种水分问题不仅会被患者注意到，还会中断采样过程。在这项研究中,我们旨在开发3D打印网格覆盖的流体收集架（MFCR），以解决表面水分问题，以确定MFCR是否可以缩短采样时间。方法：这是一个观察性的，描述性,描述性和横断面研究。我们观察了使用或不使用MFCR的患者中与表面水分问题相关的采样中断的原因（2022年4月28日至30日）。我们用3D打印机做了一个MFCR，其测量宽度和长度为14.5厘米，高度为1.0厘米。MFCR允许乙醇通过网状物排出到下面的流体收集架中,以在网状物上留下相对干燥的表面。最后,我们计算了MFCR和非MFCR之间完成采样的中位时间。结果：共随机观察400例患者（使用MFCR，n=200；非MFCR，n=200)。与MFCR组（n=3，1.5％）相比，非MFCR组的患者更有可能通过注意到表面水分问题来中断采样过程（n=39，19.5％）。两个主要的中断，“询问有关潮湿表面的问题”（从12％到1％）和“放慢行动”（从4.5％到0.5％），通过使用MFCR得到了明显的改进。总的来说,与使用非MFCR组(1.5min)相比,使用MFCR组(0.6min)的中位采样时间显著缩短(p<0.001).MFCR将采样时间缩短了60%，这可能与减少由表面水分问题引起的中断有关。结论：3D打印的MFCR适用于处理由重复消毒引起的表面水分问题。更重要的是,MFCR可能与减少由水分问题引起的中断有关。
