A proposal for a LU-based approach to triage and admission during outbreaks with high-volume influx of patients. There is not enough evidence, yet, to recommend specific LU criteria over others, but we hypothesize these may be the most useful ones. During resource constraint phases, feasibility and throughput volume can be maximized by the use of LU, followed by CT when appropriate.
