Proportion of stillbirths from 28 weeks’ gestation where substandard care for FGR detection or management are identified

Maternity services impact

Proportion of term births with undetected FGR defined as severely growth restricted singletons (less than 3rd centile) undelivered at 40 weeks’ gestation (missed FGR)

Outcome
