Two recent studies tried again to identify predictors of eventual ICU requirement...

Effect on mortality?
Despite a more stable initial presentation, mortality of patients who decompensated on the floor (25%) matched that of patients initially admitted to the ICU.
*One of the studies noted that although respiratory rate was demonstrated to be the most important vital sign, it was missing in 42% of the study population, while PCO2 was only obtained in 39% of patients.
