Abstract

Background: Perinatal mental health (PMH) conditions are associated with an increased risk of adverse perinatal outcomes including preterm birth. Midwifery caseload group practice (continuity of care, MCP) improves perinatal outcomes including a 24 % reduction of preterm birth. The evidence is unclear whether MCP has the same effect for women with perinatal mental health conditions.

Aim: To compare perinatal outcomes in women with a mental health history between MCP and standard models of maternity care. The primary outcome measured the rates of preterm birth.

Methods: A retrospective cohort study using routinely collected data of women with PMH conditions between 1st January 2018 - 31st January 2021 was conducted. We compared characteristics and outcomes between groups. Multivariate logistic regression models were performed adjusting for a-priori selected variables and factors that differ between models of care.

Results: The cohort included 3028 women with PMH, 352 (11.6 %) received MCP. The most common diagnosis was anxiety and depression (n = 723, 23.9 %). Women receiving MCP were younger (mean 30.9 vs 31.3, p = 0.03), Caucasian (37.8 vs 27.1, p < 0.001), socio-economically advantaged (31.0 % vs 20.2, p < 0.001); less likely to smoke (5.1 vs 11.9, p < 0.001) and with lower BMI (mean 24.3 vs 26.5, p < 0.001) than those in the standard care group. Women in MCP had lower odds of preterm birth (adjOR 0.46, 95 % CI 0.24-0.86), higher odds of vaginal birth (adjOR 2.55, 95 % CI 1.93-3.36), breastfeeding at discharge (adj OR 3.06, 95 % CI 2.10-4.55) with no difference in severe adverse neonatal outcome (adj OR 0.79, 95 % CI 0.57-1.09).

Conclusions: This evidence supports MCP for women with PMH. Future RCTs on model of care for this group of women is needed to establish causation.
