The document discusses the organization and levels of neonatal intensive care units (NICUs). NICUs are designed to provide intensive monitoring and life-saving therapies to critically ill newborns, especially preterm and low birth weight babies. They aim to reduce neonatal mortality and morbidity. NICUs require adequate facilities, staffing, and space to treat common neonatal problems. Care is divided into four levels depending on the needs of the newborn, from basic care at home or primary health centers to highly specialized regional NICUs that can manage complex conditions.
