Sudden unexplained early neonatal death or collapse: A national surveillance study

Abstract

Background:The incidence of sudden unexpected early neonatal death (SUEND) or acute life-threatening events (ALTEs) is reported as 0.05/1,000 to 0.38/1,000 live births. There is currently no national system in Australia for reporting and investigating such cases.Methods:A 3-y prospective, national surveillance study, run in collaboration with the Australian Pediatric Surveillance Unit (APSU). Data were provided by pediatricians reporting to APSU; and independently ascertained by the Coroner in two states (NSW and QLD) and the Newborn Early Transport Network in NSW. A detailed deidentified questionnaire was created.Results:In NSW and QLD, the incidence was 0.1 and 0.08/1,000 live births, respectively. Forty-eight definitive cases were identified. Common causes included accidental asphyxia, cardiac disease, persistent pulmonary hypertension of the newborn, and sudden infant death syndrome. Twenty-six babies collapsed on day 1 and 19 were found on the carer's chest.Conclusion:The incidence in NSW and QLD is higher than previously published. The first postnatal day is a vulnerable period for newborns, who require close observation particularly during skin-to-skin contact. Development and implementation of guidelines for safe sleeping in hospital are needed. Collaboration between obstetricians, midwives, and pediatricians is essential to ensure safety of the newborn.
