  1. Hospital non-survivors were more severely ill (SAPS II; P < 0.05) and exhibited significantly more organ dysfunctions (TMS; P < 0.05) compared with the patients completing the follow-up of 5 years. Age is given as of the day of ICU admission. aSignificant difference between all patients and those who survived the hospital stay (P < 0.05). GCS, Glasgow Coma Scale; ICU, intensive care unit; NA, not applicable; PRM, predicted risk of mortality; SAPS II, Simplified Acute Physiology Score II; SD, standard deviation; TISS-28, Therapeutic Intervention Scoring System; TMS, total maximum Sequential Organ Failure Assessment.
