Note. N = 728,266. COPS2 = Comorbidity Point Score, Version 2; ED = emergency department; ICU = intensive care unit; LAPS2 = Laboratory-Based Acute Physiology Score, Version 2; LOS = length of stay; Mdn = median.
a
LAPS2 measures acute physiologic instability during the 72 hours preceding admission; the higher the score, the greater the mortality risk due to acute physiologic derangement.
b
COPS2 is a longitudinal score based on 12 months of patient data; the higher the score, the greater the mortality risk due to comorbid illness.
