Weight loss is normal for healthy newborns in the first few days, especially for those exclusively breastfed, who may have low enteral intake for several days. Although most newborns tolerate this early period of weight loss well, those with pronounced weight loss become at increased risk of feeding problems and hyperbilirubinemia, which are the two most common causes of neonatal readmission. To facilitate the assessment of risk for an individual newborn, the Newborn Weight Tool (NEWT) has been developed to categorize each infant's weight loss according to population norms, so that formula can be administered when weight loss is pronounced and avoided when weight loss is normal. The Healthy Start study will be a randomized, controlled trial testing whether displaying NEWT to clinicians providing newborn care can improve neonatal health outcomes including formula use, weight loss and readmission. Newborns will be randomly assigned either to display weight with NEWT weight categorization to their providers in the electronic health record (EHR) or to usual care (weight displayed without NEWT categorization).
