Ancillary referral patterns in infants after initial assessment in a cardiac developmental outcomes clinic.

At the time of presentation, nearly 1 in 3 infants required referral. Referral patterns did not vary by traditional risk stratification. Sociodemographic factors and co-morbid medical conditions increased the likelihood of referral. This supports the need for routine follow-up for all post-surgical infants regardless of level of surgical complexity. Further research into the completion of referrals and long-term referral patterns is needed.
