Pre-hospital use of inhaled corticosteroids and inhaled beta agonists and incidence of ARDS: A population-based study.

Objective: Inhaled corticosteroids and inhaled beta agonists were shown to decrease the lung injury in animal models. We investigated the association of pre-hospital use of inhaled corticosteroids and inhaled beta agonists with the incidence of Acute Respiratory Distress Syndrome (ARDS) in a population based cohort of hospitalized patients.

Material And Methods: Retrospective cohort study of adult patients from Olmsted County, Minnesota admitted to the hospital with at least one predisposing condition for ARDS from 2001-2008.
