There are a few randomized controlled trials (RCTs) comparing outpatient balloon catheters with inpatient vaginal dinoprostone, but the reported outcomes among these trials were inconsistent, justifying the need for a meta-analysis. We aimed to evaluate the effectiveness and safety of inpatient vaginal dinoprostone compared to outpatient balloon catheters for cervical ripening in labor induction.</p><p><strong>Material and methods: </strong>Eligible RCTs were identified using MEDLINE, Emcare, Embase, Scopus, CINAHL Plus, Cochrane Pregnancy and Childbirth Group's Trials Register, WHO International Clinical Trials Registry Platform, and clinicaltrials.gov from inception to July 2024. Women with live singleton pregnancies at 34 or more weeks of gestation were eligible. The authors of eligible trials were invited to share their de-identified data. The main outcomes were vaginal birth and a composite adverse perinatal and maternal outcome. All analyses were adjusted for age and parity. Two-stage random effects meta-analysis was the main analysis strategy with the intention-to-treat principle. This meta-analysis was registered with PROSPERO (CRD42022313183) on 27-04-2022.</p><p><strong>Results: </strong>We identified three eligible RCTs, and all three shared data (N = 1636); inpatient vaginal dinoprostone (n = 832), outpatient balloon catheter (n = 804). The odds of vaginal birth were higher after inpatient vaginal dinoprostone than outpatient balloon catheter (67.8% vs 61.7%, adjusted odds ratio [aOR] 1.30, 95% CI 1.05-1.62, I² = 0%). There was no significant difference in the composite adverse perinatal outcome (13.7% vs 13.1%, aOR 1.09, 95% CI 0.75-1.58, I² = 28.7%) or the composite adverse maternal outcome (16.6% vs 19.8%, aOR 0.81, 95% CI 0.61-1.07, I² = 11.5%).

In pre-planned subgroup analysis, for pregnant women with underweight/normal weight, both inpatient vaginal dinoprostone and outpatient balloon catheter methods are viable options, but balloon catheter has a lower vaginal birth rate in women with overweight and obesity during pregnancy.

The HR of spontaneous delivery decreased with increasing placental to fetal ratio (HR 0.013 (95% CI: 0.001–0.121), Wald statistic 14.704 (<i>p</i> &lt; 0.001)), indicating a longer duration of pregnancy with a higher placental to fetal ratio at gestational week 27. The HR of spontaneous delivery also decreased with increasing placental size, but the association was less prominent than the HR associated with placental to fetal ratio (HR 0.997 [95% CI: 0.995–0.999], Wald statistic 7.638 [<i>p</i> = 0.006]). We estimated no association with fetal size (HR 1.001 [95% CI 0.999–1.003], Wald statistic 1.728 [<i>p</i> = 0.189]).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Our findings suggest that the placental to fetal ratio at gestational week 27 may be an indicator of the remaining duration of pregnancy until the onset of spontaneous labor.</p>\u0000 </section>\u0000 </div>","PeriodicalId":6990,"journal":{"name":"Acta Obstetricia et Gynecologica Scandinavica","volume":"104 5","pages":"913-921"},"PeriodicalIF":3.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aogs.15082","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
