OBJECTIVE: Guidelines for the management of neonatal hyperbilirubinemia have helped to reduce rates of significant hyperbilirubinemia. However, recent evidence suggesting overtreatment and potential harms of phototherapy have informed the American Academy of Pediatrics clinical practice guideline revision and the accompanying increase in phototherapy thresholds. These changes are predicted to safely reduce overuse; however, to date, the exact effect of these guidelines has not been established.
METHODS: We conducted a retrospective study of newborns born at ≥35 weeks\' gestation across a network of 8 hospitals between January 2022 and June 2023. Outcomes included rates of phototherapy and total serum bilirubin (TSB) measurements before and after guideline publication, as well as clinical outcomes, including length of stay, readmissions, and duration of phototherapy.
RESULTS: In our cohort of >22 000 newborns, we observed a 47% decrease in phototherapy utilization, from 3.9% to 2.1% (P < .001). TSB measurements were reduced by 23%, from 712 to 551 measurements per 1000 newborns (P < .001), without an increase in outpatient TSB measurements. We did not observe an increase in readmissions receiving phototherapy, and length of stay increased by only 1 hour (P < .001).
CONCLUSIONS: Our study reveals that the publication of the updated American Academy of Pediatrics 2022 hyperbilirubinemia guidelines has likely yielded a significant reduction in phototherapy use and serum bilirubin measurement. Dedicated quality improvement initiatives may help determine which implementation strategies are most effective. Further population-level studies are needed to confirm safety with ongoing guideline uptake.

UNASSIGNED: Neonatal hyperbilirubinemia is one of the most common conditions for neonate inpatients. Indonesia faces a major challenge in which different guidelines regarding the management of this condition were present. This study aimed to compare the existing guidelines regarding prevention, diagnosis, treatment and monitoring in order to create the best recommendation for a new hyperbilirubinemia guideline in Indonesia.
UNASSIGNED: Through an earlier survey regarding adherence to the neonatal hyperbilirubinemia guideline, we identified that three main guidelines are being used in Indonesia. These were developed by the Indonesian Pediatric Society (IPS), the Ministry of Health (MoH), and World Health Organization (WHO). In this study, we compared factors such as prevention, monitoring, methods for identifying, risk factors in the development of neonatal jaundice, risk factors that increase brain damage, and intervention treatment threshold in the existing guidelines to determine the best recommendations for a new guideline.
UNASSIGNED: The MoH and WHO guidelines allow screening and treatment of hyperbilirubinemia based on visual examination (VE) only. Compared with the MoH and WHO guidelines, risk assessment is comprehensively discussed in the IPS guideline. The MoH guideline recommends further examination of an icteric baby to ensure that the mother has enough milk without measuring the bilirubin level. The MoH guideline recommends referring the baby when it looks yellow on the soles and palms. The WHO and IPS guidelines recommend combining VE with an objective measurement of transcutaneous or serum bilirubin. The threshold to begin phototherapy in the WHO guideline is lower than the IPS guideline while the exchange transfusion threshold in both guidelines are comparably equal.
UNASSIGNED: The MoH guideline is outdated. MoH and IPS guidelines are causing differences in approaches to the management hyperbilirubinemia. A new, uniform guideline is required.

In pediatrics, accurate measurement of total serum bilirubin (TSB) is of major importance for reliable diagnosis and appropriate management of neonatal jaundice. However, several studies evidenced poor comparability of results obtained with the different available methods either in central lab or in POCT, on serum, capillary blood or transcutaneous. This situation is partly due to the lack of Reference Materials, especially for high bilirubin concentrations but also on poor communication between central lab and neonatology unit. To progress on these issues, we have compiled some data from CNRHP to propose guidelines for choice, use and management of POCT devices and to help clinical laboratories to achieve a better answer to clinical needs with specific local constraints. The results from several CNRHP studies are presented: traceability to International System of Units, inter-laboratories comparability, POCT vs central labs comparisons with POCT CO-oximeter or photometer, integration of transcutaneous bilirubinometer. We propose, based on an analysis of devices advantages and issues, guidelines to help labs either to improve neonates monitoring in their local context; we distinguished the choices inside laboratory for a better harmonization of results compared to published thresholds and outside lab contexts, to organize a coordinated chain with POCT devices, with capillary and/or transcutaneous approaches.
En néonatalogie, la mesure précise de la bilirubinémie est essentielle pour le diagnostic et le suivi de l’ictère, en regard de seuils consensuels internationaux. Toutefois, une faible comparabilité des résultats est observée entre les laboratoires de biologie médicale (LBM) et avec les dispositifs délocalisés ou transcutanés. Cette situation est en partie due à des défauts de standardisation des méthodes, mais aussi à une coordination insuffisante entre les laboratoires et les unités de soins. L’objectif de ce travail est de progresser dans l’optimisation de la prise en charge des nouveau-nés en proposant des critères de choix et d’articulation des différentes réponses biologiques, EBM, EBMD et TROD, en fonction des besoins cliniques locaux et des moyens disponibles. Les résultats de plusieurs études ciblées sur la bilirubinémie néonatale sont présentés : raccordement au système international, harmonisation interlaboratoires, comparabilité EBMD-CNRHP d’un CO-oxymètre délocalisé en maternité, comparabilité EBMD-CNRHP d’un photomètre délocalisé en maternité, intégration d’un bilirubinomètre transcutané. Nous proposons ensuite, sur la base d’une analyse critique des différents types de dispositifs, des recommandations pour aider les LBM à améliorer la prise en charge des nouveau-nés dans leur contexte local, d’une part sur la mesure de la bilirubinémie néonatale au sein du LBM et d’autre part sur l’organisation d’une chaîne coordonnée EBM – EBMD – TROD en concertation avec les unités de soins.

Background: In some hospitals in low/middle-income countries, methods to determine the bilirubin level in newborn infants are unavailable and based on a clinical evaluation, namely a clinical score designed by Kramer. In this study, we evaluated if this score can be used to identify those infants that need phototherapy. Method: Infants admitted between November 2018 and June 2019 to three hospitals in Surabaya, Indonesia were included. The jaundice intensity was scored using the Kramer score. Blood was sampled for total serum bilirubin (TSB) measurement. The infants were categorized into Treatment Needed (TN) group when treatment with phototherapy was indicated and the No Treatment Needed (NTN) group when phototherapy was not indicated, based on the Indonesian Guideline for hyperbilirubinemia. Result: A total of 280 infants with a mean birth weight of 2744.6 ± 685.8 g and a gestational age of 37.3 ± 2.3 weeks were included. Twenty-seven of 113 (24%) infants with Kramer score 2 needed phototherapy, compared with 41 of 90 (46%) infants with score 3 and 20 of 28 (71%) of infants with score 4. The percentage of infants that needed phototherapy was higher with decreasing gestational age. Conclusion: The Kramer score is an invalid method to distinguish between those infants needing phototherapy and those infants where this treatment is not indicated.

The SFBC-CNBH-CNRHP \"Neonatal bilirubin\" working group performed a biological and clinical study on bilirubin use in neonates for reliable diagnosis and appropriate management of neonatal jaundice. A brief report of a national survey on analytical and biological practices in France is shown. The guidelines of the French Society of Neonatology (SFN) founded the decision of phototherapy set up upon an accurate lab measurement of total serum bilirubin. An abacus is proposed with defined thresholds, as a function of neonate lifetime in hours. However, several studies evidenced poor comparability of results obtained with the different available methods. This situation is partly due to the lack of reference materials, especially for high bilirubin concentrations. Clinical consequences might be observed. We present in this paper the results of a national harmonization study to progress on this issue. Beyond the analytical aspects, the clinical consequences of harmonization defects were investigated. Finally, guidelines for clinical laboratories are proposed, to be locally adapted.

Severe hyperbilirubinemia, which may result in kernicterus, is seen more frequently in low and middle-income countries, such as Indonesia, than in high-income countries. In Indonesia midwives, general practitioners (GPs), and pediatricians are involved in the care of jaundiced newborn infants. It is unknown whether the high incidence of severe hyperbilirubinemia in this country is related to a lack of awareness of existing hyperbilirubinemia guidelines issued by, for example, the World Health Organization, the American Academy of Pediatrics, or the Indonesian Health Ministry, or to a lack of adherence to such guidelines. The aim of this questionnaire study was to assess health professionals\' awareness of existing guidelines and their adherence to these guidelines in daily practice. We handed out a ten-question questionnaire to midwives, GPs, and pediatricians that included questions about the professionals themselves as well as clinical questions. The midwives completed 291 questionnaires, the GPs 206, and the pediatricians 154, all of which we used for our analysis. Almost 30% of the midwives and 23% of the GPs were either unaware of any existing guidelines or they did not adhere to them. Only 54% of the midwives recognized the warning signs of severe hyperbilirubinemia correctly, compared to 68% of the GPs and 89% of the pediatricians. Twenty-eight percent of the midwives and 31% of the GPs indicated that their first follow-up visit was after 72 hours, while 90% of them discharged infants after less than 48 hours after birth. The awareness of and adherence to guidelines for preventing and treating hyperbilirubinemia is low amongst the midwives and GPs in Indonesia. This may be an important contributing factor in the high incidence of severe hyperbilirubinemia in Indonesia.

OBJECTIVE: This study compared the use of phototherapy for neonatal jaundice in all 21 Norwegian neonatal intensive care units (NICUs) from 2013-2014 to improve practice.
METHODS: Information on all types of phototherapy devices was collected, and irradiance was measured from random units at 20 cm and 50 cm from the light source. We gathered information on local practice rules, including the use of single, double or triple phototherapy, how infants were positioned, the frequency of blood sampling, rules for using reflective surfaces and interrupting phototherapy. In every NICU, we asked one nurse with more than five years of experience and one with less than one year to set up phototherapy equipment, then measured the irradiance and distance.
RESULTS: Photodiodes were the most common of the eight types of phototherapy devices used. Rules for the distance from the device to the infant varied from 10 to 40 cm and in practice they varied from 15 to 48 cm, with irradiance ranging from 11.1-56.1 W/m2 . There were significant variations between NICUs with regard to the overall treatment duration and duration in most birthweight categories.
CONCLUSIONS: There were considerable variations in phototherapy practices among Norwegian NICUs. In particular, the significant variations in duration need to be addressed.
