Mothers of children with major congenital anomalies have increased health care utilization over a 20-year post-birth time horizon.

Mothers of infants with a major congenital anomaly had greater health care utilization across services. Health care utilization decreased over time or remained stable for outpatient, inpatient, and surgical care services, whereas psychiatric utilization increased for up to 13 years after an affected child's birth.
