The questionnaire covered approximately a third of all preterm deliveries and nearly half of the preterm deliveries before 32 gestational weeks. The diagnostic criterion for PL was either painful uterine contractions or cervical dilatation.

Prophylactic antibiotics to maintain pregnancy were administered for pPROM at approximately 90% and for PL at approximately 20% of institutions.
