Neonatal outcomes
Neonatal outcomes of the two study groups are presented in Table
3 . We observed differences between the low annual volume and the high
annual volume in the following outcomes: higher rates of neonatal
jaundice (4.1% vs. 3.7%, p<0.01), higher rates of mechanical
ventilation rates (0.3% vs 0.2%, p<0.01), and higher rates
of composite adverse neonatal outcome (10.9% vs. 10.3%,
p<0.01). Other neonatal outcomes were comparable between the
study groups.
Multivariate regression analysis adjusted for: maternal age,
parity, gestational age, TOLAC, oxytocin augmentation, persistent
occipito-posterior and CNMs’ practice duration revealed an independent
significant positive risk association between low annual volume and
mechanical ventilation, neonatal jaundice, and composite adverse
neonatal outcome (aOR 1.32, 95% CI [1.05-1.66], aOR 1.07, 95% CI
[1.00-1.14]. and aOR 1.05 (1.01-1.09) respectively)
