US regulations mandate annual N95 mask fit testing for healthcare workers, but the optimal testing interval is unknown. In our study using data from 12,565 healthcare workers, the probability of survival free from fit-test failure after 3 years was 99.4%, suggesting that less frequent fit testing every 3 years would be safe.
美国法规要求医护人员每年进行 N95 口罩适配性测试,但最佳测试间隔时间尚不清楚。在我们的研究中,使用了来自 12565 名医护人员的数据,3 年后无适配性测试失败的生存概率为 99.4%,这表明每 3 年进行一次频率较低的适配性测试是安全的。
