3.8 Risk Assessment (3/3) Copy

    The recommended initial obstetric review of pregnancies considered at increased risk should determine next steps according to severity and unit policy. 
  • Phase I: Pregnancies considered high risk should be referred to maternal-fetal medicine (MFM) services, where available, for investigation and review:
    • if the uterine artery (UtA) Doppler at 20-23 weeks’ gestation is normal these women can follow the moderate risk pathway
    • if the UtA Doppler at 20-23 weeks’ gestation is abnormal these women should continue under MFM surveillance. 
    • Where MFM services are not available, frequent assessment from 24 weeks throughout the third trimester is recommended.
  • Phase II: Pregnancies considered high risk can have UtA Doppler between
    20-23 weeks’ gestation in the ultrasound department, with referral to MFM if abnormal.
