Clinical guideline reduces time to phototherapy in neonatal jaundice

A nurse-driven clinical practice guideline (CPG) for neonatal jaundice significantly reduced time to phototherapy initiation in a pediatric emergency department, according to findings presented at the Pediatric Academic Societies 2026 Meeting. The intervention, designed using a multidisciplinary, evidence-based approach, focused on rapid identification and treatment of neonates with hyperbilirubinemia.¹

Hyperbilirubinemia affects approximately 60% of neonates and remains a leading cause of hospital readmission in the United States. Elevated bilirubin levels can result in bilirubin-induced neurologic dysfunction (BIND), a preventable but serious complication. Phototherapy is a well-established intervention that reduces the risk of BIND and the need for exchange transfusion, underscoring the importance of timely treatment.²

In the study, conducted at Monroe Carell Jr. Children’s Hospital at Vanderbilt, implementation of the CPG reduced median time to phototherapy from 96 minutes to 53 minutes and increased the proportion of infants receiving treatment within 1 hour of arrival.

In a recent interview with Don Arnold, MD, MPH, professor of pediatrics and emergency medicine at Vanderbilt University School of Medicine, the investigator emphasized that operational changes—rather than new technology—drove the improvement.

“Having phototherapy lights in the ED and empowering our nurses to initiate phototherapy as soon as the neonate was placed in a room was key,” Arnold said. “Nurses are patient advocates, and they are enthusiastic about providing the neonate what is needed – phototherapy.”

Why is rapid identification of at-risk neonates critical?

Arnold highlighted the need for pediatric emergency departments to prioritize early identification and triage of neonates at risk for hyperbilirubinemia-related complications.

“Based on the results of our study and the risk of BIND, identifying these neonates to be at risk and triaging them appropriately, perhaps at an Emergency Severity Index level of 2 or 3, will facilitate expeditious implementation of phototherapy,” Arnold explained.

The study data support this emphasis on timeliness. Because neurologic injury can occur with sustained high bilirubin levels, delays in treatment may increase risk. Arnold also pointed to workflow bottlenecks identified in the analysis.

“We learned from the Kaplan-Meier plot… that we need to expedite getting these patients to a room for phototherapy.”

How did nurse-initiated phototherapy change ED workflow?

A central component of the CPG was empowering nursing staff to initiate phototherapy before physician evaluation, a shift that altered traditional emergency department workflows.

According to Arnold, this approach streamlined care delivery but also introduced operational challenges.

“The greatest challenge was room availability during times of high volume,” Arnold said. “This can be seen in the Kaplan-Meier plot in which some neonates in the post-CPG group waited for several hours before phototherapy initiation.”

Another concern involved the potential to initiate treatment before confirming the bilirubin thresholds. However, this risk did not materialize in practice.

“A second challenge was to balance the potential for initiating phototherapy when serum bilirubin was below the phototherapy threshold,” Arnold noted. “Because neonates were referred to our ED from outside facilities…there were no instances of inappropriate phototherapy.”

These findings suggest that protocol-driven care can be implemented safely when paired with appropriate patient selection and referral patterns.

What steps can other pediatric settings take to replicate these results?

Arnold provided practical recommendations for community pediatricians and smaller emergency departments seeking to reduce time to treatment.

“Potential steps to reduce time to phototherapy include, first, expeditiously triaging and rooming these patients and, second, having a standing order that empowers nurses to initiate phototherapy and obtaining blood for bilirubin levels before the patient is evaluated by physicians or APP’s,” Arnold said.

These strategies align with the broader goals of the CPG, which aim to reduce the time to phototherapy to less than 1 hour from presentation.

The study authors concluded that implementing an evidence-based CPG for neonatal jaundice was associated with a clinically meaningful reduction in time to treatment and an increased likelihood of receiving phototherapy within 1 hour. Although the study did not assess long-term clinical outcomes, earlier treatment may reduce the risk of BIND.
