Example
- Terminal illness
- Yes
- Septic shock
- Yes
- Age > 65 years
- Yes
Result: MEDS 12/27: moderate risk (28-day mortality ~7.8%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-7
- very low 0-4 (~0.9% 28-day mortality) and low 5-7 (~2.0%).
- 8+
- moderate 8-12 (~7.8%), high 13-15 (~20%), and very high >= 16 (~50%).
What you enter
- Terminal illness (< 30-day expected mortality)

- Septic shock
- Platelets < 150,000/mm^3
- Bands > 5%
- Age > 65 years
