miniPIERS (bedside pre-eclampsia risk)
miniPIERS — the bedside-only pre-eclampsia adverse-outcome model from parity, gestational age, headache/visual changes, chest pain/dyspnea, vaginal bleeding with abdominal pain, SBP, and dipstick proteinuria.

Example
- Multiparous
- Yes
- Gestational age
- 34 weeks
- Systolic blood pressure
- 160 mmHg
- Dipstick proteinuria; lt2 is negative, trace or 1+, the reference category
- 3+
- Headache or visual changes
- Yes
Result: miniPIERS 10% probability of adverse maternal outcome within 48 h: at or below 15% -- lower risk.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- > 15%
- Increased surveillance.
- >= 25%
- High risk (rule-in; positive likelihood ratio about 5).
What you enter
- Multiparous
- Gestational age
- Systolic blood pressure
- Dipstick proteinuria; lt2 is negative, trace or 1+, the reference category
- Headache or visual changes
- Chest pain or dyspnea
- Vaginal bleeding with abdominal pain
How this is calculated
- Inputs
- parity, gestational age, headache/visual, chest pain/dyspnea, vaginal bleeding with pain, systolic BP, dipstick proteinuria -- no labs.
