1. What is the PRISM III Score?

The PRISM III (Pediatric Risk of Mortality III) score is a physiologically based mortality risk assessment tool for pediatric intensive care units. It evaluates the risk of mortality based on 17 physiologic variables.

2. How Does the Calculator Work?

The calculator sums points assigned to various physiologic variables:

Each variable is assigned points based on how far it deviates from normal ranges.

3. Importance of PRISM III Score

Details: The PRISM III score helps predict mortality risk in pediatric ICU patients, allowing for better resource allocation and treatment planning.

4. Using the Calculator

Tips: Enter all required physiologic measurements. The calculator will sum the points based on the severity of abnormalities.

5. Frequently Asked Questions (FAQ)

Q1: What age group is PRISM III for?
A: PRISM III is validated for children from birth up to 18 years of age.

Q2: How is PRISM III different from PRISM IV?
A: PRISM IV is a newer version with updated coefficients and additional variables, but PRISM III remains widely used.

Q3: What is a normal PRISM III score?
A: Lower scores indicate lower mortality risk. Scores above 20 are associated with high mortality risk.

Q4: When should PRISM III be calculated?
A: Typically within the first 12-24 hours of PICU admission using the worst values during that period.

Q5: Can PRISM III predict individual outcomes?
A: No, it predicts population risk and should not be used to predict outcomes for individual patients.
