Abstract

Background: A better understanding of the overuse of antenatal care is needed to improve its organisation to deal with limited medical resources and doctor shortages.

Objectives: To assess the proportion of women who overuse antenatal care and the associations of overuse with maternal characteristics and the qualifications of healthcare providers.

Methods: We used the 2016 National Perinatal Survey, a cross-sectional population-based survey, performed in all maternity units in France, including 13,132 women. Based on the French national guidelines, 6-8 antenatal visits were defined as adequate, 9-11 as high use, and ≥12 as overuse, while 3 ultrasounds were considered adequate, 4-5 as high use, and ≥6 as overuse. We performed binary modified Poisson regressions-with adequate care as the reference-including maternal social and medical characteristics and the healthcare professionals' qualifications.

Results: After women with inadequate care were excluded, 19.2% of low-risk women had at least 12 visits and 30.5% at least 6 ultrasounds. Overuse of visits was associated with primiparity, average to high income, less than good psychological well-being, and care by an obstetrician. The risks of overuse of ultrasounds were higher among primiparous, women with average to high income and those receiving care from a public-sector obstetrician (adjusted relative risk 1.17, 95% CI, 1.13, 1.21) or private obstetrician (adjusted relative risk 1.12, 95% CI, 1.07, 1.16), compared with a public-sector midwife.

Conclusions: Antenatal care overuse is very common in France and associated with some maternal characteristics and also the qualification of care provider. Antenatal care should be customised according to women's needs, in particular for primiparae and those with poor well-being, and available medical resources.
