Preterm PROM (PPROM) (ie &lt;37\u2009weeks gestation) precedes one\u2010third of preterm births, exposing the fetus to increased morbidity from placental abruption, respiratory distress syndrome and sepsis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>To analyse trends in the incidence and mode of birth in preterm and term PROM in Victoria, Australia between 2009 and 2017.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>This retrospective population\u2010based cohort study included all singleton pregnancies from 2009 to 2017. We examined women with PROM (both &lt;37\u2009weeks (PPROM) and at term). Management was assessed in three categories: (a) expectant management; (b) induction of labour (IOL); and (c) elective caesarean section (elCS). A multinomial logistic regression model was used to adjust for confounders influencing the choice of management.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 636\u2009590 singleton pregnancies, 52\u2009669 (8.3%) births with PROM at term (42\u2009439; 6.7%) or PPROM (10\u2009230; 1.6%) were identified. Of these, the majority were managed expectantly <jats:italic>(n<\/jats:italic>\u2009=\u200922\u2009726; 43.1%), or with IOL (25\u2009931; 49.2%). While elCS represented only 7.6% of these cases (<jats:italic>n<\/jats:italic>\u2009=\u20094012), its use rose consistently from 2009 to 2017 for PROM at term and PPROM alike. For women with PPROM at 34\u201336\u2009weeks the odds of elCS increased by 5% annually (adjusted odds ratio (aOR) 1.05; 95% CI 1.02\u20131.08) and 2% for IOL (aOR 1.02; 95% CI 1.00\u20131.05) vs expectant management.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The use of elCS and IOL in PPROM is rising in Victoria, particularly between 34 and 36 completed weeks of pregnancy.
