MOEWS — Modified Obstetric Early Warning Score

Modified obstetric early warning system (MEOWS/MOEWS; CEMACH 2007, validated by Singh 2012): a trigger is one red or two yellow parameters.

Used in: Pre-eclampsia & Obstetric Emergencies

Score interpretation

No Trigger 0

All parameters in the normal (white) zone.

→ Continue observations at the planned frequency.

One Yellow Parameter — No Trigger 1

One moderately abnormal parameter: not a trigger on its own.

→ Repeat observations sooner and inform the midwife in charge if it persists.

MEOWS Trigger 2

One red or two yellow parameters: the chart has triggered.

→ Urgent medical (obstetric) review; escalate to senior obstetric and anaesthetic staff as the chart's escalation plan specifies.

Interpretation bands for the MOEWS. Apply clinical judgement and local guidance.
