The MPM at 24 hours (MPM-24) collects data from the 24 hour period after the patient was admitted to the ICU.
Parameters:
(1) level of consciousness at 24 hours
(2) cancer
(3) admission to the ICU
(4) prothrombin time in seconds
(5) shock during the first 24 hours
(6) urine output during any 8 hour period during the first 24 hours
(7) infection confirmed at 24 hours
(8) PaO2 in mm Hg in first 24 hours
(9) FIO2 in first 24 hours
(10) serum creatinine in first 24 hours
(11) age in years
(12) hours of mechanical ventilation
(13) number of lines at 24 hours
(14) service assignment at 24 hours
