<p><strong>OBJECTIVE: </strong>Create a prioritization framework for value-based improvement in neonatal care.</p>

<p><strong>STUDY DESIGN: </strong>A retrospective cohort study of very low birth weight (&lt;1500 g) and/or very preterm (&lt;32 weeks) infants discharged between 2012 and 2019 using the Pediatric Health Information System Database. Resource use was compared across hospitals and adjusted for patient-level differences. A prioritization score was created combining cost, patient exposure, and inter-hospital variability to rank resource categories.</p>

<p><strong>RESULTS: </strong>Resource categories with the greatest cost, patient exposure, and inter-hospital variability were parenteral nutrition, hematology (lab testing), and anticoagulation (for central venous access and therapy), respectively. Based on our prioritization score, parenteral nutrition was identified as the highest priority overall.</p>

<p><strong>CONCLUSIONS: </strong>We report the development of a prioritization score for potential value-based improvement in neonatal care. Our findings suggest that parenteral nutrition, central venous access, and high-volume laboratory and imaging modalities should be priorities for future comparative effectiveness and quality improvement efforts.</p>

<p><strong>OBJECTIVE: </strong>To rank clinician-driven tests and treatments (CTTs) by their total cost during the birth hospitalization for preterm infants.</p>

<p><strong>STUDY DESIGN: </strong>Retrospective cohort of very low birth weight (&lt;1500 g) and/or very preterm (&lt;32 weeks) subjects admitted to US children's hospital Neonatal Intensive Care Units (2012-2018). CTTs were defined as pharmaceutical, laboratory and imaging services and ranked by total cost.</p>

<p><strong>RESULTS: </strong>24,099 infants from 51 hospitals were included. Parenteral nutrition ($85M, 32% of pharmacy costs), blood gas analysis ($34M, 29% of laboratory costs), and chest radiographs ($18M, 31% of imaging costs) were the costliest CTTs overall. More than half of CTT-related costs occurred during 10% of hospital days.</p>

<p><strong>CONCLUSIONS: </strong>The majority of CTT-related costs were from commonly used tests and treatments. Targeted efforts to improve value in neonatal care may benefit most from focusing on reducing unnecessary utilization of common tests and treatments, rather than infrequently used ones.</p>
