SARS among critical care nurses, Toronto.

摘要: To determine factors that predispose or protect healthcare workers from severe acute respiratory syndrome (SARS), we conducted a retrospective cohort study among 43 nurses who worked in two Toronto critical care units with SARS patients. Eight of 32 entered patient’s room were infected. The probability infection was 6% per shift worked. Assisting during intubation, suctioning before and manipulating the oxygen mask high-risk activities. Consistently wearing (either surgical particulate respirator type N95) while caring for patient protective nurses, consistent use N95 more than not mask. Risk reduced by mask, but significantly. lower We conclude activities related to intubation increase risk (particularly mask) is protective.
