Subspecialty neonatal training enables NICU graduate monitoring, premature-infant developmental tracking, and high-risk newborn transition management beyond standard well-child protocols. Acute pediatric presentations requiring after-hours evaluation route through same-campus urgent-care resources at Access Medical Centers for stabilization before Rady Children's Hospital transfer when indicated.
