PRISM III

Pediatric Risk of Mortality III: 17 physiological variables with age-dependent limits, 0–74 points

Details

Age

Circulation and neurology

Systolic blood pressure (lowest) (mmHg)

Empty fields are treated as normal.

Heart rate (highest, not while crying) (/min)

Temperature (lowest or highest) (°C)

Glasgow Coma Scale (lowest, not within 2 h after sedation)

Pupillary reaction

Acid-base and blood gases

pH (lowest)

If only one pH value is available, enter it here only; it is scored for both acidosis and alkalosis.

pH (highest, if different)

Total CO₂ (lowest) (mmol/l)

Total CO₂ (highest) (mmol/l)

pCO₂ (highest) (mmHg)

PaO₂ (lowest, arterial) (mmHg)

Chemistry

Glucose (highest)

Potassium (highest) (mmol/l)

Creatinine (highest)

Urea N (BUN, highest)

Hematology

Leukocytes (lowest) (/µl)

Platelets (lowest) (/µl)

Prothrombin time (PT) (s)

PTT (s)

Mortality model PRISM IV (Pollack 2016)

Estimate mortality according to PRISM IV (values from the PRISM IV time window)

Frequently asked questions

PRISM III: What does this calculator compute?

PRISM III (Pollack 1996): points for the worst values of the first 12 or 24 hours – blood pressure, heart rate, temperature, consciousness, pupils, acid–base status, blood gases, glucose, potassium, creatinine, blood urea nitrogen, white cells, platelets and coagulation – with the four age groups; optionally the probability of death according to the public PRISM IV model (Pollack 2016) with its time window.
