Clinician diagnosis of pre-eclampsia, based on the ISSHP definition: a blood pressure ≥140/90mmHg AND either:
1. Significant proteinuria (protein/creatinine ratio (PCR) of 30 mg/mmol or more) OR
2. Maternal multiorgan dysfunction:
a. Acute kidney injury (AKI) (creatinine ≥90 μmol/L)
b. Liver involvement (elevated transaminases e.g. alanine transaminase (ALT) or aspartate transaminase (AST) >40IU/L) with or without right upper quadrant or epigastric abdominal pain)
c. Neurological complications (including eclampsia, altered mental status, blindness, stroke, clonus, severe headaches, persistent visual scotomata)
d. Haematological complications (thrombocytopenia – platelet count below 150,000/μL, DIC, haemolysis) OR
3. Uteroplacental insufficiency (fetal growth restriction, abnormal Umbilical artery doppler, stillbirth)
developing at or after 20 weeks gestation.
