Managing the Historic Burden of Kernicterus Mortality in India.

Abstract

Prevention of neonatal bilirubin injury exemplifies success of systems approach to avert adverse neonatal and childhood outcomes that rely on strategies including prenatal identification of Rhesus sensitization, universal maternal blood typing, risk assessment for neonatal extreme hyperbilirubinemia (EHB), unfettered access to safe, effective phototherapy, and application of patient safety principles. India's diverse landscape suggests varied real-time experiences of neonatal hyperbilirubinemia and consequent infant mortality rates (IMR). Utilizing Global Burden of Disease (GBD) database, the authors examined national and subnational trends, infant mortality timing, and the disease burden from hemolytic and perinatal jaundice over 30 y (1999 to 2019). They also assessed the correlation of EHB-IMR with socio-demographic index and health expenditure per capita, estimating economic losses from EHB-related infant mortality to guide policy decisions at national and state domains. From 1990 to 2019, India delivered 811,078,415 livebirths of which, 1,189,856 infant deaths were due to EHB. EHB-related deaths decreased from 57,773 in 1990 to 19,664 in 2019, a 60% reduction vs. 40% in overall IMR. Early (0-6 d), late (7-27 d), and post-neonatal (28-364 d) deaths accounted for 61%, 34%, and 5% of mortality, respectively. Uttar Pradesh and Bihar contributed to 38% of all EHB deaths. Economic analysis estimate losses between US $7.2 and 11.7 billion for the year 2019 secondary to EHB-related mortality. The present analysis reveals consistent declines across all states to reach current EHB-IMR of 0.8 per 1,000 live-births in India by 2019. Significant economic impact of lost human productivity highlight ongoing need for targeted life-saving public health strategies.
