Control description
jaundice, depression
Clusters randomized to the control arm receive routine individualized WCC at an urban, hospital-owned academic pediatric practice located 5 city blocks from the opioid treatment program. This practice site includes 14 physicians and nurse practitioners, serves a predominantly Medicaid-insured population, and is a training environment for students and residents. Newborns are scheduled for an initial 30-min visit within 3–5 days after discharge home, with any additional 15-min visits in the first few weeks of life as needed (i.e., for jaundice or a weight check). Subsequent 15-min WCC visits occur at recommended intervals per American Academy of Pediatrics recommendations (1, 2, 4, 6, 9, 12, 15, 18, 24, 30, and 36 months of age). Routine care in this practice setting includes maternal depression screening, provision of books as part of a national literacy promotion program, developmental screening, and social determinants of health screening. A dedicated RN coordinator tracks receipt of preventative services for all patients and provides outreach to patients who no-show for WCC, and access to subspecialty care, social work, and lactation services are available on-site. Scheduling of visits may occur in-person at the registration desk, through an online patient portal, or by telephone. Phone or text appointment reminders are provided the day before scheduled visits.
