适应性测试P2/N95呼吸器没有降低医疗保健工作者COVID-19感染风险. 这项研究建议重新考虑广泛的呼吸器适应性测试,以防止医疗保健工作者感染.
科学领域:
- 职业健康 职业健康 职业健康
- 传染病流行病学 传染病流行病学
- 呼吸系统保护 呼吸系统保护
背景情况:
- 建议卫生保健工作者 (HCW) 配备测试P2/N95呼吸器,以尽量减少传染性气溶暴露.
- 很少有研究评估了呼吸器适应性测试是否有效地降低了HCWs中的COVID-19感染率.
研究的目的:
- 评估P2/N95呼吸器适应性测试与医疗保健工作者COVID-19感染风险之间的关联.
- 为了确定医疗保健机构中HCW中COVID-19感染的风险因素.
主要方法:
- 从2020年9月起,对澳大利亚墨尔本1571个高危人群的回顾性队列研究.
- 进行了定量适应性测试和关于COVID-19风险因素的问卷.
- 在该计划之前被诊断出COVID-19的HCW与未被感染的HCW相匹配,以比较风险因素,包括适应性测试结果.
主要成果:
- 在1571名HCW中,4.6%被诊断出患有COVID-19. 年龄较小,护理角色,与病例密切接触,以及病房暴露时间较长与感染有关.
- 在对职业暴露强度进行调整后,密切接触仍然是COVID-19的唯一独立风险因素 (OR 3.50).
- 适当的P2/N95呼吸器适应性测试与COVID-19感染风险降低无关 (OR 1.08).
结论:
- P2/N95呼吸器适应性测试与HCWs的COVID-19感染风险较低无关,即使在控制职业暴露后也是如此.
- 在预防HCW COVID-19感染方面,广泛的呼吸器适应测试计划的有效性需要重新评估.
