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

Objective: To 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. Design: A prospective cohort study. Population and setting: Self-selected pregnant women from midwifery care settings (n=401). Methods: W-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 measures: The 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. Results: High 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. Conclusion: This 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). Nonurgent 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.
