• The technology described in this briefing is Novii Wireless Patch System. It is used for maternal and fetal monitoring.

  • The innovative aspects are the technology is wireless and does not need to be adjusted by the midwife when the baby or transducer moves.

  • The intended place in therapy would be as an alternative to standard cardiotocography (CTG) monitoring using a wired transducer and belt for women who need monitoring during labour.

  • The main points from the evidence summarised in this briefing are from 6 studies (1 randomised controlled trial, 2 secondary analyses, 2 observational studies and 1 equivalence study) including a total of 487 women in late pregnancy (n=228) and labour (n=259). They show that Novii is as effective as standard monitoring, is likely to be more effective in people with a high body mass index and may reduce maternal heart rate and fetal heart rate confusion during second stage labour.

  • Key uncertainties around the evidence or technology are that half of the studies have been published on a previous version of the technology. In the studies using the previous version of the technology most of the women were not in labour.

  • The cost of the Novii system is £4,995 and the Novii Wireless Patch System is about £35 per person (excluding VAT). The Novii system can only be used with the GE Corometrics 259cx Maternal Fetal Monitor (£6,600). The Novii system can be cost saving if the NHS trust already has a GE Corometrics 259cx Monitor. The cost of standard care (CTG monitoring) would be about £7,000 for the maternal fetal monitor depending on different options and about £30 per person for the belt, gel and fetal scalp electrode.
