Complications are more common among women with Medicaid or no insurance compared to those with private insurance.

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.
