Intrauterine growth restriction (IUGR) is present in fetuses that do not achieve their full in-utero growth potential. IUGR needs to be discriminated from small for gestational age (SGA) because IUGR newborns in particular experience long-term side effects from their small growth. IUGR fetuses have a significantly increased risk of prematurity and a distinct risk profile compared to adequate-for-gestational-age preterm newborns. Complications of prematurity are more frequent, including bronchopulmonary dysplasia, intraventricular hemorrhage, and meconium ileus. IUGR newborns are at risk of long-term health issues like cerebral palsy, impaired lung function, and delayed speech development. Interdisciplinary and interprofessional care of IUGR pregnancies in the context of a standardized health care research project is feasible: Pregnant women at risk are identified, early therapy with acetylsalicylic acid is started as indicated, risk-adapted care at level III centers is organized including psychosocial interventions and neonatal consultations. Postnatally, integrated neonatal care focusing on parent-child interaction and optimized nutrition is a hallmark. Afterwards, in-depth pediatric follow-up visits with local pediatricians help to identify growth and neurodevelopment problems early. The effects, acceptance. and cost efficiency of this approach are evaluated prospectively as part of an Innovationsfonds project.
