Extremely preterm prelabour rupture of membranes (EPPROM) is a rare complication of pregnancy; it is frequently quoted to have an incidence of less than 1% 1,2 but the exact incidence is unclear.
It is currently unknown how women who experience EPPROM are counselled and managed across the UK.
National guidance for EPPROM is not therefore underpinned by good quality scientific evidence.

EPPROM is a rare complication of pregnancy that carries significant maternal morbidity, neonatal morbidity and neonatal mortality. The true incidence of women undergoing ongoing conservative management for ‘prolonged EPPROM’ is difficult to establish from current literature due to different inclusion criteria and gestational age windows. It is unclear how this group of women is counselled and managed as there is currently a paucity of good quality data available and guidance for clinicians. Expectant mothers in the UK are presented with huge variation in information on prognosis and advice on termination. When conservative management is chosen, variation exists in location of management, use of monitoring, antibiotics and steroids. There is urgent need to develop an understanding of the characteristics of babies that survive EPPROM and accurate complication rates.
To use the UK Obstetric Surveillance System (UKOSS) to estimate the prevalence of EPPROM in the UK and examine the management of the condition as well maternal and neonatal outcomes.
