Differences in health-care utilization in women with and without inflammatory bowel diseases during preconception, pregnancy and postpartum: a population-based cohort study


Background and Aims — Compared to those without inflammatory bowel disease [IBD], women with IBD may have increased healthcare utilization during pregnancy and postpartum, though this remains to be confirmed. We aimed to characterize this healthcare use between these groups.

Methods — Administrative databases were accessed to identify women [aged 18–55 years] with and without IBD who had a live, singleton pregnancy between 2003 and 2018. Differences in emergency department [ED] visits, hospitalizations and prenatal care during 12 months preconception, pregnancy and 12 months postpartum were characterized. Multivariable negative binomial regression was performed to report incidence rate ratios [IRRs] with 95% confidence intervals [95% CIs]. Covariates included maternal age at conception, location of residence, socioeconomic status and maternal comorbidity.

Results — In total, 6163 women with IBD [9158 pregnancies] and 1091 013 women without IBD [1729 411 pregnancies] were included. Women with IBD were more likely to visit the ED [IRR 1.13, 95% CI 1.08–1.18] and be hospitalized [IRR 1.11, 95% CI 1.01–1.21] during pregnancy, and visit the ED [IRR 1.21, 95% CI 1.15–1.27] and be hospitalized [IRR 1.18, 95% CI 1.05–1.32] during postpartum. On unadjusted analysis, women with IBD were more likely to be hospitalized for venous thromboembolic events. There was no difference in healthcare use in preconception. Finally, women with IBD also had a greater number of prenatal visits during pregnancy and were more likely to receive a first-trimester prenatal visit.

Conclusion — Women with IBD have increased healthcare utilization during pregnancy and postpartum. Efforts should be made to increase ambulatory care access during this period, which in turn may reduce this health-services utilization.
