Emergency department utilisation and critical readmission in patients with Fontan circulation.

In this multi-centre study, nearly half of patients with Fontan circulation received emergency department care, often presenting with high disease acuity requiring readmission. Emergency department utilisation and need for critical readmission were independently influenced by the centre at which surgery was performed, prolonged post-operative hospitalisation, and racial background. These data could help guide quality improvement efforts aimed at reducing morbidity in this unique patient population.
