Organization of Smoking Cessation in Pregnant Women With the Implementation of the 5A Strategy in New Aquitaine.

The investigators are conducting a pragmatic cluster randomized trial in stepped-wedge of which objectives are to evaluate the effectiveness and the conditions of effectiveness of an organizational strategy for smoking cessation - 5A-QUIT-N - among pregnant women in New Aquitaine (NA), by using and optimizing existing resources

In France, in 2016, 16.6% of pregnant women were smokers, the highest levels among European countries. Pregnancy is considered a teachable moment for smoking cessation. There are many tools, interventions and programs to reduce the smoking habits of pregnant women. The challenge is therefore not to propose new interventions but to understand what is hindering the implementation of existing interventions and proposing corrective measures. In this context, the scientific literature shows that interventions for smoking pregnant women only seem effective when based on a comprehensive approach that combines multiple interventions. In particular, interventions based on the 5A's model (Ask, Advise, Assess, Assist, Arrange) are largely recommended and have shown their effectiveness abroad. Factors facilitating or hindering the implementation of such strategies are mainly organizational. As organizations are context-dependent by nature, considering the generalization of such strategies in France therefore requires adapting them to the French health system and evaluating them in context, in a pragmatic approach, inserted into routine care and using the tools, procedures and existing organizations in the territories.

* Healthcare professionals: the target of the 5A-QUIT-N intervention from whom data will be collected to meet the secondary objective of the effectiveness conditions.
* Stakeholders: individuals involved in the implementation of the research and intervention from whom data will be collected to meet the secondary objective of the effectiveness conditions.
* Women who have just given birth and who smoke tobacco in early pregnancy: indirect beneficiaries of the intervention, from whom data will be collected to meet the primary objective of effectiveness.
* Co-parent (partner) of the new-born child of the woman who has just given birth included in the study
