Preterm premature rupture of membranes (PPROM) is the main cause of premature delivery, complicating 1-3% of all pregnancies. Conventional hospitalization (CH) is the most frequent mode of follow-up, but homecare (HC) seems to be an alternative. Study of the impact of the monitoring mode on the duration of the latency period and on the latency ratio after PPROM, and analysis of the risk factors modifying this ratio. This was a bicentric retrospective cohort study here-abouts including patients who presented a PPROM between 24 and 36weeks of gestation from 2016 to 2018. Patients had a follow-up in HC at Lille University Hospital center (UHC) and in CH at Nantes UHC according to two different follow-up protocols. The latency ratio corresponded to the real latency period divided by the latency period to theoretical term. We included 154 patients: 102 in HC and 52 in CH. The mean latency period was significantly higher in HC: 36.9±21.8 days, corresponding to an 85.5±23.7% latency ratio versus 20.2±12 days, corresponding to an 66.9±29.8% latency ratio in CH (P
