Facteurs organisationnels associes a l'education prenatale et impact sur l'accouchement assiste dans deux contextes a risques maternels et neonatals eleves au Burkina Faso

Maternal and neonatal mortality remain high in developing countries. The magnitude of these phenomena is related to a constellation of factors. But a significant proportion of adverse pregnancy and birth outcome, in poor area, are attributable to preventable and behaviourally modifiable causes. Prenatal educational interventions have been developed in order to address the factors affecting the demand for effective maternal and neonatal care. Educational strategies targeting pregnant women include individual counselling, group sessions, and the combination of both strategies. These strategies aim to improve knowledge on issues related to maternal and newborn health and to promote the appropriate use of skilled care and hygiene practices at home. The World Health Organization (WHO) released practice guidelines in developing countries related to maternal and neonatal care including birth preparedness, during routine prenatal visits. However, few data are available about the effectiveness and implementation of effective prenatal education in these countries. This thesis aims to understand the impact of prenatal education programs in two contexts in Burkina Faso where maternal and neonatal risk are high. Written in the form of articles, the thesis addresses three specific objectives namely to: 1) examine the efficacy of prenatal education programs to reduce maternal and neonatal mortality in developing countries, 2) assess the association between different organizational factors and women's exposure to birth preparedness messages during routine antenatal care, and 3) determine the impact of receiving birth preparedness advice on the likelihood of institutional delivery. For the first objective, a meta-analysis of data from randomized trials was conducted. To achieve the two other objectives, data from a retrospective cohort study were used. This observational study, designed specifically for the thesis, was conducted in two districts (Dori and Koupela) in Burkina Faso. The meta-analysis showed that educational interventions are associated with a 24% reduction in neonatal mortality. This reduction reached 30% in areas with very high neonatal mortality. In routine situations, organizational factors may limit or facilitate the transmission of educational advice to women using prenatal care. In Burkina Faso, the data indicate significant disparities between the two districts in the study. Women from Koupela district were significantly more exposed to advice than those from Dori. Beyond this regional disparity, two other organizational factors were strongly associated with exposure of women to birth preparedness counselling during routine prenatal visits. The first factor was the availability of print materials and aids (e.g., posters, pictures...), used by health professionals as communication support to provide prenatal clients with advice. The second factor was a lower volume of daily consultations (i.e., less than 20 consultations versus 20 or more) which meant lower workload for staff. Finally, advice received by women concerning signs of obstetric complications and costs of care were associated with a significantly higher likelihood of institutional deliveries but only in the district of Dori where the initial rate of institutional deliveries was relatively low. In conclusion, prenatal education is beneficial for maternal and newborn health. However, implementation and effect heterogeneities exist across contexts. Others experimental and observational studies are required to strengthen the evidence and more thoroughly investigate success factors in order to support policies. Future experiments should focus on maternal outcomes (i.e., skilled birth attendance, postpartum care, and maternal mortality). Prospective cohort studies with large and representative samples would allow for examination of events and exposures to interventions during pregnancy, childbirth, and post-partum.;Keywords : Prenatal education, Birth preparedness, maternal mortality, neonatal mortality, skilled birth attendance, prenatal care, developing countries, Burkina Faso...
