- Brief Summary
Preterm birth is a leading cause of childhood mortality and developmental disabilities. Socioeconomic disparities in the incidence of preterm birth and morbidities, mortality, and quality of care for preterm infants persist. An important predictor of the long-term consequences of preterm birth is maternal presence during the prolonged infant hospitalization (weeks to months) in the neonatal intensive care unit (NICU). Mothers who visit the NICU can pump breast milk, directly breastfeed and engage in skin-to-skin care, which facilitates breast milk production and promotes infant physiologic stability and neurodevelopment. Low-income mothers face significant barriers to frequent NICU visits, including financial burdens and the psychological impact of financial stress, which hinder their participation in caregiving activities. The investigators will conduct an randomized controlled trial (RCT) to test the effectiveness of financial transfers among 420 Medicaid - eligible mothers with infants 24 - 34 weeks' gestation in four level 3 NICUs: Boston Medical Center (BMC) in Boston, Massachusetts, UMass Memorial Medical Center (UMass) in Worcester, Massachusetts, Baystate Medical Center in Springfield, Massachusetts, and Grady Memorial Hospital in Atlanta, Georgia. Mothers in the intervention arm will receive usual care enhanced with weekly financial transfers and will be informed that these transfers are meant to help them spend more time with their infant in the NICU vs. a control arm (usual care). The primary hypothesis is that financial transfers can enable economically disadvantaged mothers to visit the NICU, reduce the negative psychological impacts of financial distress, and increase maternal caregiving behaviors associated with positive preterm infant health and development.

Group Intervention Description Financial Transfers Financial Transfers Mothers assigned to the intervention group will be informed that they are eligible to receive financial transfers $160/week on a "CuddleCard" debit-card with a one- time "label" or scripted message that states: "This money is intended to help you to spend more time visiting and caring for your infant(s) in the NICU." Financial transfers will begin 1 week after birth or when the mother is discharged (whichever comes later) until the infant is discharged, except in cases where the hospitalization lasts beyond 42 weeks corrected age.
