Abstract

OBJECTIVES: To investigate the survival up to age 10 years for children born alive with a major congenital anomaly.

METHODS: This population-based linked cohort study (EUROlinkCAT) linked data on live births during 2005-2014 from 13 European congenital anomaly registries with mortality data. Pooled Kaplan-Meier survival estimates up to 10 years of age were calculated for these children (77,054 children with isolated structural anomalies and 4,011 children with Down syndrome).

RESULTS: The highest mortality of children with isolated structural congenital anomalies was within infancy, with survival of 97.3% (95% CI, 96.6-98.1) and 96.9% (95% CI, 96.0-97.7) at age 1 and 10 years, respectively. The 10-year survival exceeded 90% for the majority of specific congenital anomalies (27/32), with considerable variations between congenital anomalies of different severity. Survival of children with a specific isolated anomaly was higher than in all children with the same anomaly when those with associated anomalies were included. For children with Down syndrome, the 10-year survival was significantly higher for those without associated cardiac or digestive system anomalies (97.6%; 95% CI, 96.5-98.7) compared to children with Down syndrome associated with a cardiac anomaly (92.3%; 95% CI, 89.4-95.3), digestive system anomaly (92.8%; 95% CI 87.7-98.2) or both (88.6%; 95% CI, 83.2-94.3).

CONCLUSIONS: Ten-year survival of children born with congenital anomalies in Western Europe during 2005-2014 was relatively high. Reliable information on long-term survival of children born with specific congenital anomalies is of major importance for parents of these children and for the health care professionals involved in their care.
