Neurocognitive outcomes in children following immersion: a long-term study.

OBJECTIVE: To investigate long-term neurocognitive outcomes after a near-drowning incident in children who were deemed neurologically intact on discharge from hospital.

DESIGN: A prospective cohort study of near-drowning children.

SETTING: 95 drowning and near-drowning admissions, 0-16 years of age, from January 2009 to December 2013, to The Children's Hospital at Westmead, Sydney, NSW, Australia.

PARTICIPANTS: 23 children both met the criteria and had parental consent for the study.

MAIN OUTCOME MEASURES: Identification of the long-term deficits in behaviour, executive function, motor skills, communicative skills and well-being over a 5-year period. Assessment was undertaken at 3-6 months, 1 year, 3 years and 5 years after near-drowning at clinic visits. Physical developmental screening and executive function screening were done using Behavior Rating Inventory of Executive Function-Preschool version (BRIEF-P) and BRIEF.

RESULT: 95 drowning and near-drowning episodes occurred during the study period. 10 (11%) children died, 28 were admitted to the paediatric intensive care unit and 64 directly to a ward. 3 children died in emergency department, 7 children had severe neurological deficit on discharge from the hospital. 23 were subsequently recruited into the study; 5 (22%) of these children had abnormalities in behaviour and/or executive function at some during their follow-up.

CONCLUSION: Children admitted to hospital following a near-drowning event warrant long-term follow-up to identify any subtle sequelae which might be amenable to intervention to ensure optimal patient outcome.
