Note. N = 1,661. HAPI stages are based on the 2007 National Pressure Ulcer Advisory Panel definitions. COPS2 = Comorbidity Point Score, Version 2; DTI = deep tissue injury; LAPS2 = Laboratory-Based Acute Physiology Score, Version 2.
a
The lowest score in the first 24 hours.
b
LAPS2 is a measure of acute physiologic instability during the 72 hours preceding admission; the higher the score, the greater the mortality risk due to acute physiologic derangement.
c
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.
