- Scoring on ITU
- Generally consist of 2 parts
- Severity score
- Calculated mortality
- Classification
- Simple scales
- Based on clinical judgement
- Anatomical
- Mainly for trauma (eg abbreviated injury score AIS)
- Disease specific
- Eg Ranson's for pancreatitis, Child-Pugh
- Therapeutic weighted
- Eg therapeutic intervention scoring system (TISS)
- Organ specific
- Eg Sepsis-related Organ Failure Assessment (SOFA)
- Physiological assessment
- Based on routinely measured variables (APACHE)
- Ideal scoring
- Based on easily recorded variables
- Well calibrated
- High level of discrimination
- Applicable to all patient populations
- Used in different countries
- Ability to predict quality of life after ICU discharge
- Common scoring systems
- Acute physiological and chronic health evaluation (APACHE)
Link:reference.medscape.com/calculator/apache-ii-scoring-system
- Assesses pre-existing disease, patient reserve and severity of acute illness
- Simple acute physiology score (SAPS)
Link:www.opus12.org/SAPS_II.html
- Score obtained in first 24hrs by assessment of 12 variables in the latest version
- Mortality prediction model (MPM)
- Assessment of chronic health, acute diagnosis and physiological variables allow prediction of death to be made. Data on admission and 24hrs post ITU admission is used
- SOFA
Link:clincal.com/icumortality/SOFA.aspx
- Based on 6 organ systems (respiratory, CV, CNS, renal, coagulation and liver - each weighted 1-4). Final score of 4-24
- Multiple organ dysfunction score (MODS)
Link:reference.medscape.com/calculator/mods-score-multiple-organ-dysfunction
- Based on 6 organ systems: resp (pO2:FiO2 ratio), renal (creatinine), hepatic (bilirubin), CV (pressure-adjusted HR), haem (platelets), CNS (GCS) with weighted scores of 0-4. Allows day-to-day prediction
