To undertake a survey of external cephalic version (ECV) in the United Kingdom and Republic of Ireland.
In June 1995 every consultant obstetrician and gynaecologist in the United Kingdom and Republic of Ireland was sent a postal questionnaire which asked whether ECV was routinely performed for breech presentation after 37 weeks of gestation, assuming no contraindications. If consultants did not perform ECV, a supplementary question inquired whether they referred patients to a colleague who would perform ECV. The questionnaires were colour coded for country and dispatched from the Postgraduate Education Department of the Royal College of Obstetricians and Gynaecologists (RCOG).
Overall, 78% of questionnaires were returned. The percentage of consultants routinely practising ECV in each country was as follows: Northern Ireland 82%; Scotland 64%; Republic of Ireland 64%; England 43%; and Wales 41%. When these figures were compared with the latest RCOG Annual Statistical Returns for breech delivery and caesarean section for breech delivery, there was an inverse correlation between the percentage of obstetricians performing ECV in any one country and the incidence of breech delivery (P < 0.001). There was a similar inverse correlation for the percentage of obstetricians performing ECV and the caesarean section rate for breech delivery (P < 0.001).
Although postal survey results are not necessarily an accurate reflection of what happens in clinical practice, these data are supported by evidence from the Cochrane Database of Systematic Reviews indicating that ECV after 37 weeks reduces the incidence of both breech delivery and caesarean section for breech delivery.
