评估与 EMT 中 COVID-19 风险增加相关的可能因素。这项研究是在伊朗德黑兰进行的一项病例对照研究。病例组由根据逆转录酶聚合酶链反应和/或肺部计算机断层扫描结果确认的 COVID-19 EMT 组成。随机选择健康的EMT作为对照组。患者被要求填写一份清单，包括人口统计数据、与工作情况相关的数据（例如任务数量以及口罩和布料的类型）以及个人防护装备预防措施。 68 名患者和 148 名健康人分别作为病例组和对照组参加了这项研究。两名急救人员直接参与照顾患者（p<0.001）并与确诊病例队友一起工作（p<0.001），考虑戴口罩后进行密封检查等预防措施（p=0.015），用医用帽子遮住头发（p<0.001），尽管穿着防护服但不使用个人物品（p<0.001），以及脱衣时避免接触衣服外表面（p<0.001），这些都具有显着的意义两组的差异。我们发现 PPE 的类型和使用方法与 EMT 中 COVID-19 风险的增加相关。此外，我们还发现，当两名急救人员直接参与照顾患者时，以及与确诊病例队友一起工作的人员更容易受到影响。
To assess the possible factors associated with increasing risk of COVID-19 among EMTs. This study was a case-control study conducted in Tehran, Iran. Case group was consisted of confirmed COVID-19 EMTs based on the results of reverse transcriptase polymerase chain reaction and/or lung computed tomography scan. Healthy EMTs were randomly selected as control group. Patients were asked to fill out a checklist including demographic data, data related to the work situation (such as number of missions and type of mask and cloth) and PPE precautions. Sixty-eight patients and 148 healthy persons took part in this study as case and control group, respectively. Having two EMTs involved directly in taking care of patients (p<0.001) and working with a confirmed case teammate (p<0.001), considering the precautions such as seal check after wearing the mask (p=0.015), covering the hair with a medical hat (p<0.001), not using personal items despite protective clothing (p<0.001), and avoiding contact with the outer surface of clothing while removing (p<0.001) had significant difference in two groups. We found that the type and method of use of PPE were correlated with the increasing risk of COVID-19 in EMTs. Also, we found that when two EMTs were involved directly in taking care of the patients, and those who worked with a confirmed case teammate, more frequently affected.
