Preadmission exposure to air pollution and 90-day mortality in critically ill patients: A retrospective study.
We investigated the association between preadmission exposure to air pollutants and 90-day mortality in critically ill patients. ⋯ Preadmission exposure to air pollution was not associated with 90-day mortality in critically ill patients. However, a higher concentration of CO and O3 was associated with an increase in pulmonary disease-related 90-day mortality in patients with preadmission COPD.
