AimTo investigate the effect of implementation of a number of process policy guidelines (protocol), on the success rate of external cephalic version (ECV) for breech presentation.DesignProspective study.MethodsDuring a 3-year period (2004-2006) a standardized protocol for an ECV consultation was developed, evaluated and adapted. After implementing this modified protocol as 'process policy guidelines', the effect on the rate of successful ECV was prospectively evaluated during the period 1 January 2007-31 July 2008. Success was defined as cephalic presentation (ultrasound) immediately after ECV. A secondary outcome measure was the elective caesarean section rate for breech presentation.ResultsThe rate of successful ECV increased significantly from 47% (110/236 pregnant women) in the period January 2004-December 2006 to 61% (85/139, p = 0.006) in the period January 2007-July 2008. Patient characteristics were similar in both groups, with the exception of 2 subgroups of term of version. The increase was preferentially found in nulliparous and multiparous women with frank breech. Nulliparity, frank breech, anterior placenta and low birth weight were associated with a lower success rate of ECV. The term of pregnancy at which ECV was performed did not seem to affect the success rate. Implementing the process policy guidelines increased the number of cephalic presentations at delivery and decreased the rate of elective caesarean sections for breech presentation from 39% to 27% (p = 0.03). The number needed to treat to prevent 1 elective caesarean section by ECV according to the process policy guidelines was 8.ConclusionAfter implementation of the process policy guidelines, the success rate of ECV increased considerably. The rate of elective caesarean section for breech presentation declined. These findings are in favour of establishing specialized ECV centres in the Netherlands.
