[Operative delivery data in France for 2007: results of a national survey within teaching hospitals].

AIM

Clinical Practice Guidelines of the French College of Gynecologists and Obstetricians concerning operative deliveries were published in December 2008. That is why a national survey was performed for the year 2007 so as to obtain an inventory of obstetrical practices regarding the geographical distribution of the type of instrument used for operative deliveries following the level of each teaching hospital concerned.

MATERIAL AND METHODS

We included in our study 49 teaching hospitals from metropolitan France and the overseas departments and territories. For the year 2007, we noted the number of operative deliveries, the type of instrument used, as well as the level of the maternity concerned with its total number of patients, births, cesarean sections, vaginal deliveries, and episiotomies.

RESULTS

We obtained data from all 49 centres. The mean number of deliveries per year was 2203 for level I teaching hospitals, 2060 for level II and 2720 for level III, respectively. The rate of operative delivery was quite different from one centre to the other, ranging from 5.3 to 34.1% of all births. Similarly, for the type of instrument used, there existed clear geographical disparities although the notion of "School's instrument" was not as preeminent as before since most centres used at least two instruments. Moreover, the rate of cesarean varied from 9 to 29.5% (all levels concerned) with a national mean rate of 20.7% for teaching hospitals. Finally, mean rate of episiotomies ranged from 3.6 to 60%.

DISCUSSION

This study showed that important differences existed between teaching hospitals in the use of instruments and that obstetrical practices are far from being uniform. However, in 2007, the routine use of more than one instrument in each centre was most usual, as opposed to the situation some decades ago. The use of obstetrical vacuum extractors has been largely disseminated. Each of the three types of instruments has specific indications and mastering at least two instruments seems more secure in the management of the numerous obstetrical situations. It is up to teaching hospitals to make sure that the use of at least two instruments is taught for operative deliveries. The recent publication of Clinical Practice Guidelines would probably help in standardizing operative deliveries in years to come.
