    • Changes in cesarean section rates after introduction of a punitive financial policy in Georgia: A population-based registry study 2017-2019

      Background<p> <p>There is little research on how financial incentives and penalties impact national cesarean section rates. In January 2018, Georgia introduced a national cesarean section reduction policy, which imposes a financial penalty on hospitals that do not meet their reduction targets. The aim of this study was to assess the impact of this policy on cesarean section rates, subgroups of ...

METHODS Randomized controlled trial conducted at the Department of Obstetrics and Gynecology, Østfold Hospital ...

    • Factors Associated with Cesarean Section among Primiparous Women in Georgia: A Registry-based Study 

      Nedberg, Ingvild Hersoug; Rylander, Charlotta; Skjeldestad, Finn Egil; Blix, Ellen; Ugulava, Tamar; Anda, Erik Eik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-21)
      Cesarean section rates remain high in Georgia. As a cesarean section in the first pregnancy generally lead to a cesarean section in subsequent pregnancies, primiparous women should be targeted for prevention strategies. The aim of the study was to assess factors associated with cesarean section among primiparous women. The study comprised 17,065 primiparous women with singleton, cephalic deliveries ...

    • Is the operative delivery rate in low-risk women dependent on the level of birth care? : a randomised controlled trial

      Objective: To investigate possible differences in operative delivery rate among low-risk women, randomised to an alongside midwifery-led unit or to standard obstetric units within the same hospital. Design: Randomised controlled trial. Setting: Department of Obstetrics and Gynaecology, Østfold Hospital Trust, Tromsø, Norway. Population: A total of 1111 women assessed to be at low risk at onset ...

    • Labor curves based on cervical dilatation over time and their accuracy and effectiveness: A systematic scoping review

    • ST waveform analysis versus cardiotocography alone for intrapartum fetal monitoring: An updated systematic review and meta-analysis of randomized trials

      Introduction - ST waveform analysis (STAN) was introduced as an adjunct to cardiotocography (CTG) to improve neonatal and maternal outcomes. The aim of the present study was to quantify the efficacy of STAN vs CTG and assess the quality of the evidence using GRADE.<p> <p>Material and methods - We performed systematic literature searches to identify randomized controlled trials and assessed included ...

    • ST waveform analysis vs. cardiotocography alone for intrapartum fetal monitoring: A systematic review and meta-analysis of randomized trials 

      Blix, Ellen; Brurberg, Kjetil Gundro; Reierth, Eirik; Reinar, Liv Merete; Øian, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      Key message: ST waveform analysis is purposed to be better for labor surveillance than conventional CTG. We quantified the efficacy of these two methods, assessing quality of the scientific evidence with the GRADE tool, and determined that evidence is insufficient to justify the use of ST waveform analysis as intrapartum monitoring.

    • Study protocol: the Labor Progression Study, LAPS - does the use of a dynamic progression guideline in labor reduce the rate of intrapartum cesarean sections in nulliparous women? A multicenter, cluster randomized trial in Norway. 

      Bernitz, Stine; Dalbye, Rebecka; Øian, Pål; Zhang, Jun; Torbjørn, Moe Eggebø; Blix, Ellen (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-13)
      Background: <br>The increasing rate of intrapartum cesarean sections is subject of attention and concern as it is associated with adverse outcomes. Labor dystocia is one of the most frequent indications for cesarean sections even though there is no consensus on criteria for labor dystocia. Traditionally the progression of labor follows guidelines based on Friedman’s curve from the mid 1950s. In ...
