GBS is the most common cause of life-threatening infection in newborn babies in the UK.
Most developed countries offer all pregnant women a GBS test late in pregnancy and then offer antibiotics in labour when the test result is positive, and have seen significant drops in the rates of GBS infection in newborn babies. In the UK, since 2003 we have used a risk-based approach to identify which newborn babies are most likely to develop GBS infection. If a risk factor arises, the mother is offered antibiotics in labour to reduce the risk of the newborn baby developing the infection. Our rate has risen.
GBS3 is a huge clinical trial of routine testing pregnant women for group B Strep (GBS) in the UK. It is designed to establish whether testing all pregnant women is better than the UK’s current approach, and which of two testing approaches is better.
- 71 hospitals are taking part and have been randomised
- 35 hospitals are testing pregnant women and pregnant people for GBS (either offering the ECM test at 35-37 weeks of pregnancy or a rapid PCR test in labour)
- 36 hospitals are continuing with standard risk-based care
Recruitment of pregnant women and people to the GBS3 Trial will end on 31 March 2024.
The findings of this trial are expected to be reported in 2025.
We at GBSS have been closely involved right from the start of this trial, and look forward to its results informing future GBS prevention policy in the UK.
