PurposeInhaled corticosteroids (ICSs) attenuated lung injury in animal studies. We investigated the association between prehospital ICS and incidence of acute lung injury (ALI) among patients at risk.MethodsIn this ancillary analysis of the large multicenter Lung Injury Prediction Study cohort, we developed a propensity score for prehospital ICS use followed by matching, for all patients and for a subgroup of patients with at least 1 risk factor for direct pulmonary injury. The primary outcome was ALI; secondary outcomes included acute respiratory distress syndrome, need for invasive mechanical ventilation, and hospital mortality.ResultsOf the 5126 patients, 401 (8%) were using ICS. Acute lung injury developed in 343 (7%). The unadjusted incidence of ALI was 4.7% vs 6.9% (P = .12) among those in ICS compared with non-ICS group. In the "direct" lung injury subgroup, the unadjusted incidence of ALI was 4.1% vs 10.6% (P = 0.006). After propensity matching, the estimated effect for ALI in the whole cohort was 0.69 (95% confidence interval, 0.39-1.2; P = .18), and that in the direct subgroup was 0.56 (95% confidence interval, 0.22-1.46; P = .24).ConclusionsPreadmission use of ICS in a hospitalized population of patients at risk for ALI was not significantly associated with a lower incidence of ALI once controlled by comprehensive propensity-matched analysis.© 2013.
