Predictors of choice of public and private maternity care among nulliparous women in Ireland, and implications for maternity care and birth experience.
Maternity care in Ireland is provided through a mixture of free public and fee-based private or semi-private services. We examined factors associated with choice of care pathway among nulliparous women and how this influences the care they receive and their experience of childbirth using data from a prospective cohort study. Complete data were available for 1,789 women on choice of care pathway and birth outcomes, and for 1,336 women on birth experience. Maternal age (marginal effect [ME] 1.6 percentage points [ppts], p < 0.01), socioeconomic status (ME 0.5ppts, p < 0.01) and being born in Ireland (ME 10.3ppts, p < 0.01) were all positively associated with choosing private care, but level of risk in early pregnancy did not influence this decision. Intervention rates in public and semi-private care were comparable, but women in private care were more likely to receive epidural anaesthesia (odds ratio [OR] 1.65, p < 0.01) and give birth by caesarean section (ratio of relative risks [RRR] 1.98, p < 0.01). Private care was also associated with longer hospital stays (28 % longer, p < 0.01). Increased risk was negatively correlated with birth experience in public and semi-private care, but not in private care. Policies promoting the allocation of maternity care resources by level of risk, along with the standardisation of clinical practice across care pathways, could reduce rates of obstetric intervention and address risk-based disparities in birth experience outcomes.
