National trends in pediatric drowning — insights from the Israeli Ministry of Health registry-based cohort

Abstract

This study analyzes the epidemiology of pediatric drowning in Israel from 2010 to 2022, focusing on differences across age groups, sex, and regions. We conducted a retrospective cohort study using data from the Ministry of Health’s administrative databases, covering all children aged 0–17 years who were seen in the emergency department, discharged after hospitalization, or died at the scene due to drowning, excluding cases of intentional harm or suicide. The primary outcome was the annual drowning rate per 100,000 children, categorized by age, sex, and region, along with hospitalization duration, intensive care unit admissions, and mortality rates. A total of 2101 drowning incidents were identified, with 9% resulting in death. Higher drowning rates were found in younger children (1–4 years) and teenagers (15–17 years), with notable differences by sex. Drowning rates were higher in coastal regions and more frequent during winter and spring. An increase in drowning rates was observed over the last 3 years of the study (2020–2022). Children hospitalized for more than 3 days had significantly higher mortality rates, both in general wards and intensive care units.Conclusions: Pediatric drowning is a persistent public health concern in Israel, with distinct seasonal, regional, age-specific, and sex-specific patterns in incidence and mortality. This study underscores the need for a comprehensive prevention strategy that includes year-round public education, environmental safety measures, and targeted interventions for high-risk groups to reduce drowning incidents and fatalities among children effectively.What is Known:• Pediatric drowning represents a significant public health challenge globally, with varying rates.• In Israel, pediatric drowning is the second leading cause of death from all injury-related deaths. Thus far, the measures and interventions to reduce fatalities were not proven effective enough.What is New:• Pediatric drowning in Israel, with a 9% mortality rate, revealed a biphasic rate varied by sex and is higher in coastal regions and during winter and spring.• There was a notable increase in drowning incidents during the last 3 years of the study period (2020–2022), coinciding with the COVID-19 pandemic.
