Background: Ectopic pregnancy causes significant maternal morbidity and mortality. Complications are more common among women with Medicaid or no insurance compared to those with private insurance. It is unknown whether preventive care prior to pregnancy and prenatal care, which are covered by Medicaid, would decrease complications if they were more fully utilised.
Methods: Medicaid claims were used to identify a clinical cohort of women who experienced an ectopic pregnancy during 2004-08 among all female Medicaid enrolees from a large 14-state population, ages 15-44. Diagnosis and procedure codes were used to identify ectopic pregnancies and associated complications. The primary outcomes were complications associated with ectopic pregnancy: blood transfusion, sterilisation, or hospitalisation with length of stay greater than 2 days. Independent variables were documentation of preventive care within 1 year prior to the ectopic pregnancy and prenatal care within 4 months prior.
Results: Controlling for race, age, and state of residence, women's risks of any ectopic pregnancy complication were independently higher among those who did not receive any Medicaid-covered preventive care within 1 year before the ectopic pregnancy compared to those who did (RR 1.12, 95% confidence interval (CI) 1.09, 1.16), and among those who did not receive any Medicaid-covered prenatal care within 4 months prior, compared to those who did (RR 1.89, 95% CI 1.83, 1.96).
Conclusions: Pre-pregnancy and prenatal care are independently associated with decreased risk of ectopic pregnancy complications among Medicaid beneficiaries.
