Scoring systems for ICU and surgical patients:

TRIOS (Three days Recalibrated ICU Outcome Score)


Variables (Help) Value : 1 if yes, 0 otherwise (except for LODS and SAPS II admission) Beta
Transfer from ward
Chronic illness
SAPS II 2-SAPS II 3 alteration
LODS 2-LODS 3 alteration
LODS on admission 0.1536
SAPS II on admission 0.0388
Predicted death rate Logit =
Logit = Sum ( values * beta) - 4.44
Predicted death rate =
e(Logit) /(1+e(Logit))
SAPS II calculation
LODS calculation

Cohort study was conducted within medical and surgical ICUs.
All patients were over of 16 years of age.
The TRIO score is valid only for patients in ICU for at least 4 days.

Transfert from ward : was defined as an acute-bed-hospital stay of more than 24 hours before ICU admission.

The chronic health status : was assessed using APACHE II classification : presence of one or more chronic illness.

Liver insufficiency Cardiovascular
Respiratory
Renal Immuno-depression
Biopsy proven cirrhosis
Documented portal hypertension,
Episodes of past upper GI bleeding attributed to portal hypertension
Prior episodes of hepatic failure / encephalopathy / coma.
NYHA Class IV
Chronic restrictive, obstructive or vascular disease resulting in severe exercice restriction, i.e. unable to climb stairs or perform household duties.
Documented chronic hypoxia, hypercapnia, secondary polycythemia , severe pulmonary hypertension (> 40 mmHg), or respirator dependency.
Receiving chronic dialysis
The patient has received therapy that suppresses resistance to infection e.g. immuno-suppression, chemotherapy, radiation, long term or recent hight dose steroids, or has a disease that is sufficiently advanced to suppress resistance to infection, e.g. leukemia, lymphoma, AIDS.

SAPS II 2-SAPS II 3 alteration and LODS 2-LODS 3 alteration:

SAPS II 2 and LODS 2 are SAPS II and LODS measured at day 2.
SAPS II 3 and LODS 3 are SAPS II and LODS measured at day 3.
Alteration of severity scores take the value "1" when score increases and the value "0" otherwise.
