Drowning is a leading cause of injury-related death in children. In 2017, drowning claimed the lives of almost 1000 US children younger than 20 years. A number of strategies are available to prevent these tragedies. As educators and advocates, pediatricians can play an important role in the prevention of drowning.

Drowning is the leading cause of injury death in US children 1 to 4 years of age and the third leading cause of unintentional injury death among US children and adolescents 5 to 19 years of age. In 2017, drowning claimed the lives of almost 1000 US children. Fortunately, childhood unintentional drowning fatality rates have decreased steadily from 2.68 per 100 000 in 1985 to 1.11 per 100 000 in 2017. Rates of drowning death vary with age, sex, and race and/or ethnicity, with toddlers and male adolescents at highest risk. After 1 year of age, male children of all ages are at greater risk of drowning than female children. Overall, African American children have the highest drowning fatality rates, followed in order by American Indian and/or Alaskan native, white, Asian American and/or Pacific Islander, and Hispanic children. For the period 2013–2017, the highest drowning death rates were seen in white male children 0 to 4 years of age (3.44 per 100 000), American Indian and/or Alaskan native children 0 through 4 years (3.58), and African American male adolescents 15 to 19 years of age (4.06 per 100 000).
Drowning is also a significant source of morbidity for children. In 2017, an estimated 8700 children younger than 20 years of age visited a hospital emergency department for a drowning event, and 25% of those children were hospitalized or transferred for further care. Most victims of nonfatal drowning recover fully with no neurologic deficits, but severe long-term neurologic deficits are seen with extended submersion times (>6 minutes), prolonged resuscitation efforts, and lack of early bystander-initiated cardiopulmonary resuscitation (CPR).
The American Academy of Pediatrics issues this revised policy statement because of new information and research regarding (1) populations at increased risk, (2) racial and sociodemographic disparities in drowning rates, (3) water competency (water-safety knowledge and attitudes, basic swim skills, and response to a swimmer in trouble), (4) when children are in and around water (the need for close, constant, attentive, and capable adult supervision and life jacket use in children and adults), (5) when children are not expected to be around water (the importance of physical barriers to prevent drowning), and (6) the drowning chain of survival and importance of bystander CPR (Table 1).
In 2002, the World Congress on Drowning and the World Health Organization revised the definition of drowning to “the process of experiencing respiratory impairment from submersion/immersion in liquid.” Drowning outcomes are classified as “death,” “no morbidity,” or “morbidity” (further divided into “moderately disabled,” “severely disabled,” “vegetative state/coma,” and “brain death”).
The drowning process is a continuum that can be interrupted by rescue at any point in that process, with varying sequelae from no symptoms to death. Terms such as wet, dry, secondary, active, near, passive, and silent drowning should not be used.
The 2002 revised definition and classification is more consistent with other medical conditions and injuries and should help in drowning surveillance and collection of more reliable and comprehensive epidemiological information.
Certain populations, because of behavior, skill, environment, or underlying medical condition, are at increased risk of drowning.
For the period 2013–2017, the highest rate of drowning occurred in the 0- to 4-year age group (2.19 per 100 000 population), with children 12 to 36 months of age being at highest risk (3.31). Most infants drown in bathtubs and buckets, whereas the majority of preschool-aged children drown in swimming pools. The primary problem for this young age group is lack of barriers to prevent unanticipated, unsupervised access to water, including in swimming pools, hot tubs and spas, bathtubs, natural bodies of water, and standing water in homes (buckets, tubs, and toilets). The Consumer Product Safety Commission (CPSC) found that 69% of children younger than 5 years of age were not expected to be at or in the pool at the time of a drowning incident.
Adolescents (15–19 years of age) have the second highest fatal drowning rate. In this age group, just less than three-quarters of all drownings occur in natural water settings, and this age group makes up half of childhood drownings in natural water. In 2016, Safe Kids Worldwide reported that the natural water fatal drowning rate for adolescents 15 to 17 years old was more than 3 times higher than that for children 5 to 9 years old and twice the rate for children younger than 5 years of age. The increased risk for fatal drowning in adolescents can be attributed to multiple factors, including overestimation of skills, underestimation of dangerous situations, engaging in high-risk and impulsive behaviors, and substance use. Alcohol is a leading risk factor, contributing to 30% to 70% of recreational water deaths among US adolescents and adults.
Drowning is the most common cause of death from unintentional injury for people with epilepsy, and children with epilepsy are at greater risk of drowning, both in bathtubs and in swimming pools. The relative risk of fatal and nonfatal drowning in patients with epilepsy varies greatly but is 7.5- to 10-fold higher than that in children without seizures and varies with age, severity of illness, degree of exposure to water, and level of supervision. Parents and caregivers of children with active epilepsy should provide direct supervision around water at all times, including swimming pools and bathtubs. Whenever possible, children with epilepsy should shower instead of bathe and swim only at locations where there is a lifeguard. Children with poorly controlled epilepsy should have a discussion with their neurologist or pediatrician before any swim activity.
Children with autism spectrum disorder (ASD) are also at increased risk of drowning, especially those younger than 15 years of age and those with greater degrees of intellectual disability. Wandering is the most commonly reported behavior leading to drowning, accounting for nearly 74% of fatal drowning incidents among children with autism.
Exertion while swimming can trigger arrhythmia among individuals with long QT syndrome. Although the condition is rare and such cases represent a small percentage of drownings, long QT syndrome, as well as Brugada syndrome and catecholaminergic polymorphic ventricular tachycardia, should be considered as a possible cause for unexplained submersion injuries among proficient swimmers in low-risk settings.
There continue to be significant racial and socioeconomic disparities in drowning rates among children. For many, cultural beliefs and traditions may prevent children from swimming. Furthermore, for some religious and ethnic groups, single-sex aquatic settings are required, and clothing that protects modesty according to religious norms may not be allowed in some pools. Socioeconomically, the multiple swim lessons required to achieve basic water competency can be costly or difficult given limited access and transportation. Moreover, decreased municipal funding for swimming pools, for swimming programs, and for lifeguards has limited access to swim lessons and safe water recreational sites for many communities.
These barriers may be surmounted through community-based programs targeting high-risk groups by providing free or low-cost swim lessons, developing special programs to address cultural concerns as well as developing swim lessons for youth with developmental disabilities, changing pool policies to meet the needs of specific communities, using culturally and linguistically appropriate instructors to deliver swim lessons, and working with both health care and faith communities to refer patients and their families to swim programs.
Water competency is the ability to anticipate, avoid, and survive common drowning situations. The components of water competency include water-safety awareness, basic swim skills, and the ability to recognize and respond to a swimmer in trouble. Swim lessons and swim skills alone cannot prevent drowning. Learning to swim needs to be seen as a component of water competency that also includes knowledge and awareness of local hazards and/or risks and of one’s own limitations; how to wear a life jacket (previously referred to as “wearable personal flotation device”); and ability to recognize and respond to a swimmer in distress, call for help, and perform safe rescue and CPR.
Evidence reveals that many children older than 1 year will benefit from swim lessons. Swim lessons are increasingly available for a wide range of children, including those with various health conditions and disabilities such as ASD. A parent or caregiver’s decision about when to initiate swim lessons must be individualized on the basis of a variety of factors, including comfort with being in water, health status, emotional maturity, and physical and cognitive limitations. Although swim lessons provide 1 layer of protection from drowning, swim lessons do not “drown proof” a child, and parents must continue to provide barriers to prevent unintended access when not in the water and closely supervise children when in and around water.
In contrast, infants younger than 1 year are developmentally unable to learn the complex movements, such as breathing, necessary to swim. They may manifest reflexive swimming movement under the water but cannot effectively raise their heads to breathe. There is no evidence to suggest that infant swimming programs for those younger than 1 year are beneficial.
Basic swim skills include ability to enter the water, surface, turn around, propel oneself for at least 25 yards, float on or tread water, and exit the water. Importantly, performance of these water-survival skills, usually learned in a pool, is affected by the aquatic environment (water temperature, water depth, water movement, clothing, and distance), and demonstration of skills in 1 aquatic environment may not transfer to another. There is tremendous variability among swim lessons, and not every program will be right for each child. Parents and caregivers should investigate options for swim lessons in their community before enrollment to make sure that the program meets their needs and the needs of the child. High-quality swim lessons provide more experiential training, including swimming in clothes, in life jackets, falling in, and practicing self-rescue. Achieving basic water-competency swim skills requires multiple lessons, and acquisition of water competency is a protracted process that involves learning in conjunction with developmental maturation. There is a need for a broad and coordinated research agenda to address not only the efficacy of swim lessons for children age 1 to 4 years but also the many components of water competency for the child and parent or caregiver.
Drowning-Prevention Strategies The Haddon Matrix paradigm for injury prevention is used to identify interventions aimed at changing the environment, the individual at risk, and/or the agent of injury (in this case, water). Experts generally recommend that multiple “layers of protection” be used to prevent drowning because it is unlikely that any single strategy will prevent drowning deaths and injuries. The Haddon Matrix (Table 2) reveals examples of interventions before the drowning event, during the drowning event, and after the drowning event at the levels of the individual, environment, and policy. Five major interventions are evidence based: 4-sided pool fencing, life jackets, swim lessons, supervision, and lifeguards (with descending levels of evidence).
Installation of 4-sided fencing (at least 4 ft tall) with self-closing and self-latching gates that completely isolates the pool from the house and yard is the most studied and effective drowning-prevention strategy for the young child, preventing more than 50% of swimming-pool drownings of young children. Life jackets are now also well proven to prevent drowning fatalities. Some data reveal that swim lessons may lower drowning rates among children, including those 1 to 4 years of age. Lifeguards and CPR training also appear to be effective. However, data regarding the value of other potential preventive strategies, such as pool covers and pool alarms, are lacking. Interventions to prevent drowning are discussed in detail in the accompanying technical report (available online soon).
Inadequate supervision is often cited as a contributing factor for childhood drowning, especially for younger children. Adequate supervision, described as close, constant, and attentive supervision of young children in or around any water, is a primary and absolutely essential preventive strategy. For beginning swimmers, adequate supervision is “touch supervision,” in which the supervising adult is within arm’s reach of the child so he or she can pull the child out of the water if the child’s head becomes submerged under water. Evaluated interventions shown to increase the quality of supervision include swim lessons in which the need for continued parental supervision is emphasized, and a study in Bangladesh revealed that adult supervision, in addition to the physical barrier of playpens, significantly reduced the risk of drowning in children ages 1 to 5 years. Supervision should include being capable of recognizing and responding appropriately to a child in distress. Supervision is critical for safety in children with ASD and other disabilities. The National Autism Association’s Big Red Safety Box contains information for parents, schools, and first responders and suggests a safety plan in public places where there is a handoff of supervision so that children with ASD and other disabilities do not wander off.
Although supervision is an essential layer of protection when children are expected to be in or around the water, barriers must be in place to prevent unintended access of children to water during nonswim times. Drowning is silent and only takes a minute. Those children with highest drowning risk are 12 to 36 months of age. Developmentally, they are curious and lack the judgement or awareness of the dangers of water, so barriers, such as 4-sided fencing and door locks, are critical in preventing access when the caregiver is distracted by other children, meal preparation, etc.
The Model Aquatic Health Code, developed by the Centers for Disease Control and Prevention (CDC), is based on science and best practices to help guide policy makers and aquatic leaders on pool and spa safety. The Model Aquatic Health Code provides guidelines and standards for equipment, for staffing and training, and for monitoring swimming pools. Similar attention and effort are needed for open-water swim sites.
The drowning chain of survival refers to a series of steps that, when enacted, attempt to reduce mortality associated with drowning. The steps of the chain are as follows: (1) prevent drowning, (2) recognize distress, (3) provide flotation, (4) remove from water, and (5) provide care as needed. The chain starts with prevention, the most important and effective step to reducing morbidity and mortality from drowning. Rescue and resuscitation of a drowning victim must occur within minutes to save lives and reduce morbidity in nonfatal drownings and underscores the critically time-sensitive role of the parent or supervising adult.
Immediate resuscitation at the submersion site, even before the arrival of emergency medical services (EMS) personnel, is the most effective means to improve outcomes in the event of a drowning incident. Prompt initiation of bystander CPR, with a focus on airway and rescue breathing before compressions and activation of prehospital advanced cardiac life support for the pediatric submersion victim, have the greatest impact on survival and prognosis. Current guidelines recommend that drowning victims who require any form of resuscitation (including only rescue breaths) be transported to the emergency department for evaluation and monitoring, even if they appear alert with effective cardiopulmonary function at the scene.
