Summary: A survey of staff attitudes and knowledge about vaginal birth after Caesarean section (VBAC) was undertaken in Australian hospitals. There was a high response rate (67%), and over 900 responses were analysed. Generally, there was a high level of awareness about outcomes and the relative importance of many issues in considering VBAC. Registrars, consultants and midwives differed significantly in some aspects of their knowledge and attitudes to VBAC. There was also a wide range of opinion within each group. Approximately half (53%) of respondents believed patients should be actively encouraged to consider VBAC, whereas 47% felt it should be simply presented as an option.
