Can a simple assessment of fear of childbirth in pregnant women predict requests and use of non-urgent obstetric interventions during labour?

Abstract

ObjectiveTo examine whether the Wijma Delivery Expectation Questionnaire (W-DEQ-A) and the one-item Fear of Childbirth-Postpartum-Visual Analogue Scale (FOCP-VAS) - measuring high FOC - are useful tools in predicting requested and received non-urgent obstetric interventions in pregnant women. DesignA prospective cohort study. Population and settingSelf-selected pregnant women from midwifery care settings (n=401). MethodsW-DEQ-A and FOCP-VAS were assessed at two timepoints in pregnancy. Measures of non-urgent obstetric interventions which were derived from medical files were: induction of labour, epidural analgesia, augmentation with oxytocin due to failure to progress and self-requested caesarean section. Hierarchical logistics regression models were used. Main outcome measuresThe change in the Nagelkerke R2 was examined for three models predicting two outcome measures: (1) explicitly requested non-urgent obstetric interventions during pregnancy and (2) received non-urgent obstetric interventions during labour. The first model only included participants’ characteristics, the second model also included FOCP-VAS ≥5, and in the third model the W-DEQ-A ≥66 was added. ResultsHigh FOC measured with FOCP-VAS≥5 predicted requested (pseudo-R2=0.33, X2=59.82, P<0.001) and received non-urgent obstetric interventions (pseudo-R2=0.19, X2=32.81, P<0.001) better than high FOC measured with W-DEQ-A≥66. ConclusionThis study is the first evaluating self-reported FOC and postpartum based on VAS (subjective outcome) in relation to actual pregnancy and childbirth outcomes derived from medical files (objective outcome). Non-urgent obstetric interventions could already be predicted in the first half of pregnancy by means of a simple FOC assessment with the one-item FOCP-VAS. Implementing this easy to use one-item screening tool in midwifery care is suggested.
