Drowning fatalities in childhood: the role of pre-existing medical conditions
Archives of Disease in Childhood
Objectives This study is an analysis of the contribution of pre-existing medical conditions to unintentional fatal child (0-14 years) drowning and a of critique prevention stratagems, with an exploration of issues of equity in recreation. Design This study is a total population, cross-sectional audit of all demographic, forensic and on-site situational details surrounding unintentional fatal drowning of children 0-14 years in Australia for the period of 1 July 2002 to 30 June 2012. Data were sourced from the National (Australia) Coronial Information System. Age-specific disease patterns in the general population were obtained from the Australian Institute of Health and Welfare. results Four hundred and sixty-eight children drowned during the study period. Fifty-three (11.3%) had a pre-existing medical condition, of whom 19 suffered from epilepsy, 13 from autism and 5 with non-specific intellectual disabilities. Epilepsy is a risk factor in childhood drowning deaths, with a prevalence of 4.1% of drowning fatalities, compared with 0.7%-1.7% among the general 0-14 years population (relative risk: 2.4-5.8). Epilepsy was deemed to be contributory in 16 of 19 cases (84.2% of epilepsy cases) with a median age of 8 years. Asthma and intellectual disabilities were under-represented in the drowning cohort. conclusion Except for epilepsy, this research has indicated that the risks of drowning while undertaking aquatic activities are not increased in children with preexisting medical conditions. Children with pre-existing medical conditions can enjoy aquatic activities when appropriately supervised.

ObjectivesThe epidemiology of fatal drowning is increasingly understood. By contrast, there is relatively little population-level research on non-fatal drowning. This study compares data on fatal and non-fatal drowning in Australia, identifying differences in outcomes to guide identification of the best practice in minimising the lethality of exposure to drowning.DesignA subset of data on fatal unintentional drowning from the Royal Life Saving National Fatal Drowning Database was compared on a like-for-like basis to data on hospital separations sourced from the Australian Institute of Health and Welfare’s National Hospital Morbidity Database for the 13-year period 1 July 2002 to 30 June 2015. A restrictive definition was applied to the fatal drowning data to estimate the effect of the more narrow inclusion criteria for the non-fatal data (International Classification of Diseases (ICD) codes W65-74 and first reported cause only). Incidence and ratios of fatal to non-fatal drowning wi...
Drowning and near drowning in children in the United Kingdom: lessons for prevention
British Medical Journal, 1992
Objectives-To determine the pattern ofdrowning and near drowning of children in Britain and identify means of prevention. Design-Study of drowned and nearly drowned children under 15 years old. Setting-United Kingdom, 1988 and 1989. Subjects-Children under 15 years either drowning or admitted to hospital after a submersion incident. Main outcome measures-Number of nearly drowned children, obtained from consultant paediatricians returning monthly notification cards through the British Paediatric Surveillance Unit. Number of drowned children notified by the Office of Population Censuses and Surveys and other national epidemiological offices; information from coroners. Results-306 children had confirmed submersion incidents: 149 died and 157 survived after near drowning. The annual incidence in England and Wales was 1-5/100000, and mortality 0-7/100000. Mortality was lowest in public pools 6% (2/32) and highest in rivers, canals, and lakes (78%, 56/73). Most ofthe children (263, 83%) were unsupervised at the time of the accident. 208 (68%) children were under 5 years old. Conclusions-Drowning and near drowning of children are problems in the British Isles. Appropriate supervision and safety barriers seem important for preventing such accidents. Improving information on dangers of drowning given to parents through the child surveillance programmes, encouraging fencing or draining of garden ponds and domestic swimming pools, and increasing supervision of swimming in lakes, rivers, and beaches should reduce the number of accidents.
Reducing drowning deaths: the continued challenge of immersion fatalities in Australia
The Medical journal of Australia, 2010
To explore 5 years of drowning deaths in Australia compared with a previous Australian study a decade earlier, and to assess the feasibility of achieving a 50% reduction in unintentional drowning deaths by 2020. An audit of all unintentional drowning deaths in Australia using data from the National Coroners Information System for 1 July 2002 to 30 June 2007. Number and rate of drowning deaths, by age, sex, location, activity, place of birth, visitor status, and involvement of alcohol or drugs. There were 1452 drowning deaths during the study period (76.4% male). The age-adjusted rate per 100 000 people ranged from 1.61 in 2002-03 to 1.23 in 2006-07. Children aged 0-4 years had the highest rate (2.63 per 100 000 people), and 29% of deaths were of people aged 55 years or older. Over half of all deaths occurred in rivers (20.3%), at beaches (18.3%), or in swimming pools (13.3%). Alcohol was involved in 21.6% of all drowning deaths, although this varied by age. This audit suggests that ...
A Review of Nonfatal Drowning in the Pediatric-Age Group
Pediatric Emergency Care, 2017
Children up to the age of 14 years who were admitted with the diagnosis of nonfatal drowning from July 2005 to June 2015 were included. Data regarding demographics, timing, season and location of drowning, presence of an assigned lifeguard, duration of submersion and transport to hospital, cardiopulmonary resuscitation, initial Glasgow Coma Scale, temperature, pH, blood sugar level, total hospital stay, and discharge status were extrapolated, and their effects on the patient's outcome analyzed. Patients' outcomes were classified into either full recovery, moderate to severe neurological damage, or brain death. Results: Fifty-one subjects were included in the study; 66.7% were males, 57% were younger than 6 years, and 80% were Saudi citizens. Of the total cases, 94% recovered fully, and 6% were diagnosed as having brain death or discharged from the intensive care unit with severe neurological injury. Submersion time of more than 5 minutes, Glasgow Coma Scale of 4 or less, pH of less than 7.1, temperature of 35°C or less, and blood sugar of 180 mg/dL or greater were found to correlate with bad outcomes with great statistical significance. Conclusions: The findings of this study were in line with results of most of the international and local studies on the subject. Significant defects have been concluded in prehospital medical care and cardiopulmonary resuscitation. Adequate swimming safety regulations, assignments of lifeguards, and parental education should be taken into consideration by media and involved authorities.
Where children and adolescents drown in Queensland: a population-based study
BMJ Open, 2015
This retrospective population-based study examined drowning location by the site of immersion for both fatal and non-fatal drowning events in Queensland. Drowning location is not routinely collected, and this study used data linkage to identify drowning sites. The resulting enhanced quality data quantify drowning incidence for specific locations by geographic region, age group and by severity for the first time. Design: Linked data were accessed from the continuum of care (prehospital, emergency, hospital admission and death data) on fatal and non-fatal drowning episodes in children aged 0-19 years in Queensland for the years 2002-2008 inclusive. Results: Drowning locations ranked in order of overall incidence were pools, inland water, coastal water, baths and other man-made water hazards. Swimming pools produced the highest incidence rates (7.31/100 000) for overall drowning events and were more often privately owned pools and in affluent neighbourhoods. Toddlers 0-4 years were most at risk around pools (23.94/100 000), and static water bodies such as dams and buckets-the fatality ratios were highest at these 2 locations for this age group. Children 5-14 years incurred the lowest incidence rates regardless of drowning location. Adolescents 15-19 years were more frequently involved in a drowning incident on the coast shoreline, followed by inland dynamic water bodies. Conclusions: Linked data have resulted in the most comprehensive data collection on drowning location and severity to date for children in the state of Queensland. Most mortality and morbidity could have been prevented by improving water safety through engaged supervision around pools and bath time, and a heightened awareness of buckets and man-made water hazards around the farm home for young children. These data provide a different approach to inform prevention strategies.

Introduction Despite being a preventable cause of death, drowning is a global public health threat. Australia records an average of 288 unintentional drowning deaths per year; an estimated annual economic burden of 1.24billionAUD(1.24 billion AUD (1.24billionAUD(2017). On average, a further 712 hospitalisations occur due to non-fatal drowning annually. The Australian state of New South Wales (NSW) is the most populous and accounts for 34% of the average fatal drowning burden. This study aims to explore the demographics and outcome of patients who are admitted to hospitals for drowning in NSW and also investigates prediction of patients’ outcome based on accessible data. Methods and analysis This protocol describes a retrospective, cross-sectional data linkage study across secondary data sources for any person (adult or paediatric) who was transferred by NSW Ambulance services and/or admitted to a NSW hospital for fatal or non-fatal drowning between 1/1/2010 and 31/12/2019. The NSW Admitted Patient Data Collect...

Limited research considers change over time for drowning mortality among individuals under 20 years of age, or the sub-cause (method) of those drownings. We assessed changes in under-20 drowning mortality from 2000 to 2013 among 21 countries. Age-standardized drowning mortality data were obtained through the World Health Organization (WHO) Mortality Database. Twenty of the 21 included countries experienced a reduction in under-20 drowning mortality rate between 2000 and 2013, with decreases ranging from −80 to −13%. Detailed analysis by drowning method presented large variations in the cause of drowning across countries. Data were missing due to unspecified methods in some countries but, when known, drowning in natural bodies of water was the primary cause of child and adolescent drowning in Poland (56-92%), Cuba (53-81%), Venezuela (43-56%), and Japan (39-60%), while drowning in swimming pools and bathtubs was common in the United States (26-37%) and Japan (28-39%), respectively. We recommend efforts to raise the quality of drowning death reporting systems and discuss prevention strategies that may reduce child and adolescent drowning risk, both in individual countries and globally.
