Definition of abbreviations: ARF = acute respiratory failure; CI = confidence interval; iOR = interaction term odds ratio; OR = odds ratio; PI = Pacific Islander.
Presented are adjusted odds ratios of intensive care unit admission for patient race, ethnicity, the capacity strain index, and the interaction between patient race, ethnicity, and capacity strain. The race- and ethnicity-specific OR uses the odds of intensive care unit admission of White patients as the reference group. Models were built by logistic regression and fully adjusted for age, gender, insurance status, Comorbid Point Score, Laboaratory Acute Physiology Score, and study hospital.
