ICU Scoring systems

Question 1

Whats is APACHE?

Answer 1

1. Acute physiology and chronic health evaluation
2. Created in the 1980s
3. Most current is APACHE IV but II widely used
4. Physioogic values within the 1st 24 hours of admission

Question 2

What are the 3 components of APACHE?

Answer 2

1. Acute physioogy score
2. Age
3. Chronic health items

Question 3

Whats is SAPS?

Answer 3

1. Simplified acute physiology score
2. Requires the worst physiologic value within 1 hour of admission to ICU

Question 4

What is MPM?

Answer 4

1. Mortality probability model
2. Data captured within the 1st hour

Question 5

What is ICNARC

Question 6

Hospital mortality is predicted only by ?

Answer 6

1. ICNARC
2. SAPS
3. APACHE II

Question 7

APACHE IV predicts?

Answer 7

1. ICU & Hospital mortality
2. ICU & Hospital length of stay
3. Duration of mechanical ventilation
4. Need for active therapy

Question 8

What are the corhot of patients to which the scoring systems cannot be applied?

Answer 8

1. Cardiac
2. Burns

Question 9

Scoring systems that characterize specific organ dysfunction or failure?

Answer 9

1. Multiple organ dysfunction score (MODS)
2. Sepsis-related Organ Faulure Assessment (SOFA)

Question 10

Model accuracy can be measured in two ways?

Answer 10

1. Discrimination
2. Calibration

Question 11

What is discrimination in a model?

Answer 11

1. How well it predicts mortality
2. Calculated by area under the receiver operating characteristic curve (AUROC)

Question 12

Whats is calibration in a model?

Answer 12

1. Measures the extent to which a model accurately predicts probability across a population

Question 13

Methods of assessing calibration of a model?

Answer 13

1. Standardized mortality ratio (SMR)

Question 14
