Objective
To assess the associations between operating room (OR) nursing, a category of health care workers at high risk of exposure to various inhaled agents, and asthma severity/control among women with asthma.
Methods
The level of severity/control in nurses with prevalent doctor-diagnosed asthma in 1998/2000 was compared, using nominal logistic regression, in OR nursing (n=69) and administrative nursing (n=546) from the US Nurses’ Health Study for whom detailed information on asthma and nursing employment status was available.
Results
We observed a significant association between OR nursing, compared to administrative nursing, and severe persistent asthma (adjusted odds ratio 2.48, 95%CI 1.06–5.77).
Conclusions
Our findings suggest that nurses working in the operating room are at a higher risk of severe persistent asthma. Further studies with detailed estimates of occupational exposures, especially to disinfectant/cleaning agents, are warranted.
