Background and Goal of the Study:
In France, each centre can choose the optimal way to inform about Labour Epidural Analgesia (LEA), including through collective meetings. This study aims to evaluate parturients’ knowledge a priori, just after a collective briefing to estimate its effectiveness and long term recall after a free interval.

Materials and Methods:
A prospective monocentric study was conduced in our institution, from October 2015 to April 2016. Three self-questionnaires were given to parturients: the first, Q1, carried out before the information meeting; the second, Q2, completed immediately after the information meeting; the third, Q3, performed after a free interval, just before the anaesthesia visit. The questionnaire consisted in 29 closed-ended questions about LEA in obstetrics. Parturients’ socio-demographic characteristics were collected. Level of parturients’ knowledge was assessed before and after information meeting through the questionnaires. Subgroup analysis were performed according to LEA history, level of education and age. Due to non parametric distribution, Kruskal-Wallis tests were performed, followed by Wilcoxon tests with Holm correction when necessary. A p < 0.05 was considered as level of significance
Results are expressed as median [interquartile range].

Results : 
We included 296 parturients but only 93 answered the three questionnaires. Among these 93 parturients, global rates of correct answers were 45% [35 – 55], 76% [69 – 86] and 76% [66 – 83] at Q1, Q2 and Q3 respectively. Results were significantly better at Q2 and Q3, versus Q1 (p < 0.001) ; but there was no difference between Q2 and Q3 (p = 0.15). There was no significant influence of history of LEA on rates of correct answers (p = 0.08, p = 0.67 and p = 0.41 at Q1, Q2 and Q3 respectively). Age and level of education only influenced rates of correct answers at Q3 : parturients in [31 - 35 years] category had more correct answers than parturients in [≤ 30 years] category (79% [72 - 86] vs. 69% [53 - 82] respectively, p = 0.02) ; and parturients in [≥ A-level +5] group responded better than those in [< A-level +3] group (79% [71 - 85] vs. 67% [62 - 79] respectively, p = 0.03).

Conclusion :
The information provided during a collective briefing about LEA is relatively well understood and retained in the long term but remained perfectible. Adding a written information could be considered to improve the retention of information provided during the oral briefing.
