Table 2 Conditions or situations in which individual risk assessment using the Tool defaults to alternative pathways

From: The Tommy’s Clinical Decision Tool, a device for reducing the clinical impact of placental dysfunction and preterm birth: protocol for a mixed-methods early implementation evaluation study

• History of cervical surgery noted in medical history: defaults to high risk for preterm birth pathway.

• Previous baby stillborn after 24 weeks or baby born after 37 weeks weighing less than 2500g (5lb 80z) in obstetric history: defaults to high risk for placental dysfunction pathway.

• Women booking for maternity care after 13 weeks’ gestation: defaults to moderate risk for placental function pathway. This is because the placental function algorithm requires the fetal crown rump length (CRL) measurement, which is only used to date pregnancies up to 13+0 weeks’. After this time the fetal head circumference (HC) is used.

• Ruptured membranes on possible preterm labour assessment: defaults to high risk for preterm birth pathway.

• Gestational hypertension and/or gestational diabetes on changed fetal movements assessment. Care pathway defaults to high risk for placental dysfunction pathway.
