    Bilirubin Nomogram for Prediction of Significant Hyperbilirubinemia in North Indian Neonates.
    (2013-04) Pathak, Umesh; Chawla, Deepak; Kaur, Saranjit; Jain, Suksham
    Objectives: (i) To construct hour-specific serum total bilirubin (STB) nomogram in neonates born at ≥35 weeks of gestation; (ii)To evaluate efficacy of pre-discharge bilirubin measurement in predicting hyperbilirubinemia needing treatment. Design: Diagnostic test performance in a prospective cohort study. Setting: Teaching hospital in Northern India. Subjects: Healthy neonates with gestation ≥35 weeks or birth weight ≥2000 g. Intervention: Serum total bilirubin was measured in all enrolled neonates at 24±6, 72-96 and 96-144 h of postnatal age and when indicated clinically. Neonates were followed up during hospital stay and after discharge till completion of 7th postnatal day. Outcome: Key outcome was significant hyperbilirubinemia (SHB) defined as need of phototherapy based on modified American Academy of Pediatrics (AAP) guidelines. In neonates born at 38 or more weeks of gestation middle line and in neonates born at 37 or less completed weeks of gestation, lower line of phototherapy thresholds were used to initiate phototherapy. For construction of nomogram, STB values were clubbed in six-hour epochs (age ± 3 hours) for postnatal age up to 48 h and twelvehour epochs (age ± 6 hours) for age beyond 48 h. Predictive ability of the nomogram was assessed by calculating sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio, by plotting receiver-operating characteristics (ROC) curve and calculating c-statistic. Results: 997 neonates (birth weight: 2627 ± 536 g, gestation: 37.8±1.5 weeks) were enrolled, of which 931 completed followup. Among enrolled neonates 344 (34.5%) were low birth weight. Rate of exclusive breastfeeding during hospital stay was more than 80%. Bilirubin nomogram was constructed using 40th, 75th and 95th percentile values of hour-specific bilirubin. Pre-discharge STB of ≥95th percentile was assigned to be in high-risk zone, between 75th and 94th centile in upper-intermediate risk zone, between 40th and 74th centile in lower-intermediate risk zone and below 40th percentile in low-risk zone. Among 49 neonates with pre-discharge STB in high risk zone. 34 developed SHB (positive predictive value: 69.4%, sensitivity: 17.1%, positive likelihood ratio: 8.26). Among 342 neonates with pre-discharge STB in low risk zone, 32 developed PHB (negative predictive value: 90.6% and specificity: 42.5%, positive likelihood ratio: 0.37). Area under curve for this risk assessment strategy was 0.73. Conclusion: Hour-specific bilirubin nomogram and STB measurement can be used for predicting subsequent need of phototherapy. Further studies are needed to validate performance of risk demarcation zones defined in this hour-specific bilirubin nomogram.

    Evaluation of clinical profile and screening guidelines of retinopathy of prematurity in an urban level III neonatal intensive care unit
    (All India Ophthalmological Society, 2022-07) Sanghi, Gaurav; Sawhney, Jaskaran S; Kaur, Saranjit; Kumar, Neeraj
    Purpose: To evaluate the clinical profile and screening guidelines of retinopathy of prematurity (ROP) in an urban level III neonatal intensive care unit (NICU). Methods: Infants with ?2000?gm birth weight or <34 weeks gestational age were prospectively screened for ROP in an urban level III NICU between January 2018 and December 2020, based on national screening guidelines. Standard guidelines were used for ROP classification and treatment. Results: In total, 211 infants completed screening; 46 (21.8%) infants developed ROP and 13 (6.2%) had type 1 (laser treatable) ROP. Of the 46 infants with ROP, 44 (95.65%) had zone 2 and two (4.34%) had zone 1 disease. In the 102 infants with ?1500?gm birth weight, the incidence of ROP and type 1 ROP were 41.18% and 11.76%, respectively. Out of the 109 infants with >1500?gm birth weight, four (3.67%) developed ROP and one (0.91%) infant (an outborn) required treatment. Conclusion: The majority of infants developing ROP in a level III urban NICU had ?1500?gm birth weight. Zone 1 ROP was uncommon. Incidence of ROP in heavier infants (>1500?gm birth weight) was low, and treatment was required in a rare instance. In an urban NICU, the burden of ROP screening and treatments shifts to small and low?birth?weight infants
