Identifying Risk Factors Associated with Fatal Drowning Accidents in the Paediatric Population: A Review of International Evidence

Introduction: Evidence from Ireland’s Childhood Mortality Register demonstrates that drowning is the second leading cause of death in children. It occurs more commonly in adolescent males engaged in summer water-based activities and in children aged 1-4 years with access to swimming pools/unprotected water sources. Despite being an island nation, a significant lack of guidelines exists to reduce drowning accidents in these at-risk populations. Aim: Review international evidence surrounding risk factors associated with drowning accidents in the paediatric population and existing risk-reduction guidelines. Methods: Structured review of Cochrane, Cinahl, Pubmed Web of Science databases performed using search terms: (“risk factors” AND “drowning”), (“risk reduction” OR “prevention” OR “swim ability” AND “drowning”). Studies were included if satisfied age criteria (0-18 years). Results: Evidence suggests that boys are at highest risk of drowning (1-4 yrs in swimming pools; adolescents in freshwater) with inadequate surveillance, inadequate availability of first responders, certain clinical diagnoses (developmental delay and seizure disorders), lack of swimming ability, and substance misuse in adolescents all posing an increased risk. Formal swimming education in those aged 4+ years, training of supervising adults in safe rescue, installation of isolation barriers, enforcing water safety guidelines, and regulations are all recommended by International Advisory Groups for prevention of drowning. Conclusion: In Ireland, drowning is the second leading cause of accidental paediatric death in the post-neonatal period, and an important cause of childhood fatalities globally. Risk factors increasing the likelihood of fatal paediatric drownings include gender and distinct age peaks. Certain modifiable risk factors relate to peri-event factors such as lack of supervision, to post-event responses, in particular including lack of trained personnel at the scene. There is a poverty of guidelines specifically targeting the paediatric populations; guidelines generally tend to be included into adult drowning reduction strategies. Specific targeting is required to protect those most at risk.
