Drowning in the Eastern Mediterranean region: a systematic literature review of the epidemiology, risk factors and strategies for prevention

Introduction: Globally, drowning is a significant cause of preventable mortality and morbidity. The Eastern Mediterranean region (EMR) comprises 22 countries of extreme disparity in income and is a region impacted by conflict and migration. We systematically review literature published on drowning in the EMR. Methods: Peer-reviewed literature (limited to original research) was identified using Embase, PubMed, Scopus, SportsDiscus, and Web of Science databases. Literature was independently dual screened at title/abstract and full text stages with dual data extraction (20% of included studies). Studies were included if they reported epidemiology, risk/protective factors and/or prevention strategies for drowning (unintentional and intentional; fatal and non-fatal) of residents, tourists or migrants in the EMR. Literature was assessed against the [Australian] National Health and Medical Research Council’s Levels of Evidence. Results: Seventy-two studies were included in this review (epidemiology 68 studies; risk/protective factor 13 studies; prevention strategies 19 studies). Iran (n = 27), Saudia Arabia (n = 11) and Pakistan (n = 10) recorded the largest number of dedicated studies. Studies predominately focused on unintentional drowning. Ninety-two percent of included studies (n = 66) were ranked as being low evidence (level IV). The majority of studies explored drowning among children and adolescents (0–19 years). All-age fatal drowning rates varied from a low of 0.48 per 100,000 (United Arab Emirates; 2002; Ministry of Health death registry data) to a high of 18.5 per 100,000 (Egypt; 2014–15; WHO mortality database). Commonly identified risk factors included being male, young age, submersion time and resident status. Common prevention strategies public education, lifeguard supervision, and cardiopulmonary resuscitation. Discussion: Gaps in understanding of drowning burden in some countries within the region, as well as region-wide risk factor identification for adult drowning, intentional and migration-related drowning, impair the ability of nations to advance drowning prevention. There is a need for investment in implementation and evaluation of drowning prevention interventions in the EMR. Conclusion: Drowning is a significant cause of mortality and morbidity in the EMR. The recent UN declaration on global drowning prevention may provide the impetus to invest in drowning prevention research, policy, and advocacy with the aim of reducing drowning-related harms in the EMR

Assessing variations in estimates of drowning mortality in Turkey from 2013 to 2019

Introduction: Drowning is an under-recognised public health threat and a leading cause of injury-related mortality and morbidity. However, in many countries, including Turkey, limited data impair understanding of drowning burden and Global Burden of Disease (GBD) Study drowning estimates (defined using International Classification of Diseases [ICD] codes W65–74) do not include flood-related deaths (X38) and water transportation related drownings (V90, V92). A lack of accessible and reliable country-level data impacts a country’s ability to develop appropriate drowning prevention interventions and measure efficacy. This retrospective population-based study aimed to explore differences between two datasets in fatal drowning in Turkey between 2013 and 2019. Methods: National, all-age data on fatal drownings (restrictive definition: ICD-10 codes W65–74) were sourced from the Turkish Statistical Institute (TurkStat) and the Global Burden of Disease (GBD) study. In addition, a broader definition of drowning including water transport, flood-related deaths and drowning due to undetermined intent (ICD-10 codes W65–74, V90, V92, X38, Y21, T751) were sourced from TurkStat. Numeric and percentage differences in number of drowning deaths were calculated overall and by sex, age group and death year. Chi square (p < 0.05) and relative risk (95% confidence intervals) using crude drowning rates per 100,000 population were also calculated for TurkStat data. Results: From 2013 to 2019, TurkStat reported a total of 5004 drowning deaths (coded W65–74) were reported, compared to 5252 (5% difference; n = 248) using the broader definition. A restrictive definition underreported drowning most significantly in females (9.5%; n = 97), 5–9 year-olds (8.9%; n = 31) and in the 2015 calendar year (30.2%; n = 226). Males accounted for 78.8% of drowning in Turkey, with females significantly (p < 0.001) more at risk under 10 years of age (0–4 years X2 = 67.9; 5–9 years X2 = 23.9) and aged 65+ years (X2 = 29.7). GBD data overestimated a restrictive definition of drowning by 3.2% overall (7.6% for females, 52.5% for 0–4 year-olds) and underreported drowning for 65+ year-olds by 17% when compared to TurkStat restrictive definition of drowning. Conclusions: Although a restrictive definition of drowning doesn’t greatly impact estimates at a population level in Turkey, there are variations. This highlights the importance of accurate country-level drowning data to guide decision making for prevention

Child injury prevention: it is time to address the determinants of health

Injuries, although almost entirely preventable, accounted for more than 4.4 million deaths and resulted in over 520 million cases of nonfatal injury-related harm globally in 2017 [1]. Road traffic injuries, falls and drowning are leading injury mechanisms [2–4]. However, some population groups are more vulnerable to being injured than others. This Special Issue sought to unpack this concept by exploring the determinants of health and their impact on child injuries

Exploring the impact of remoteness and socio-economic status on child and adolescent injury-related mortality in Australia

Injuries are a leading cause of harm for children. This study explores the impact of determinants of health on children (0–19 years) injury-related mortality (namely remoteness and socio-economic disadvantage, calculated using the index of relative socio-economic advantage and disadvantage (IRSAD)). Cause of death data from the Australian Bureau of Statistics were sourced for children in Australia between 1 July 2007 to 30 June 2017. Fifteen injury categories (ICD-10-AM external cause codes) were used. Burden and trends by injury mechanism were explored. A total of 5153 children died; with road traffic incidents (3.39 per 100,000 population), intentional self-harm (2.46) and drowning (0.72) being the leading mechanisms. Female fatality rates in very remote areas (8.73) were nine times higher than in major cities (Relative Risk [RR] = 8.73; 95% Confidence Interval [95% CI]: 4.23–18.00). Fatality rates increased with remoteness; very remote areas recording an injury-related fatality rated six times (RR = 5.84; 95 %CI: 3.76–9.12) that of major city residents. Accidental poisoning and intentional self-harm fatalities were more likely in high IRSAD areas, while road traffic fatalities were more likely in low and mid socio-economic areas (X2 = 69.1; p < 0.001). People residing in regional and remote areas and from low socio-economic backgrounds already face significant health and lifestyle challenges associated with disadvantage. It is time to invest in injury prevention interventions for these populations, as well as upstream policy strategies to minimize any further preventable loss of life

Improving pool fencing legislation in Queensland, Australia: attitudes and impact on child drowning fatalities

Four-sided, non-climbable pool fencing is an effective strategy for preventing children from drowning in home swimming pools. In 2009, the Queensland Government introduced legislation to improve the effectiveness of pool fencing. This study explores community attitudes towards the effectiveness of these legislative changes and examines child (<5 years) drowning deaths in pools. Data from the 2011 Queensland Computer-Assisted Telephone Interviewing (CATI) Social Survey include results from questions related to pool ownership and pool fencing legislation. Fatal child drowning cases between 1 January 2005 and 31 December 2015 were sourced from coronial data. Of the 1263 respondents, 26/100 households had a pool. A total of 58% believed tightening legislation would be effective in reducing child drowning deaths. Pool owners were more likely to doubt the effectiveness of legislation (p < 0.001) when compared to non-pool owners. Perceptions of effectiveness did not differ by presence of children under the age of five. There were 46 children who drowned in Queensland home pools (7.8/100,000 pools with children residing in the residence/annum) between 2005 and 2015. While pool owners were less likely to think that tightening the legislation would be effective, the number of children drowning in home swimming pools declined over the study period. Drowning prevention agencies have more work to do to ensure that the most vulnerable (young children in houses with swimming pools) are protected

A qualitative examination of causal factors and parent/caregiver experiences of non-fatal drowning-related hospitalisations of children aged 0–16 years

Fatal and non-fatal drowning is a significant public health issue, which disproportionately impacts children and young people. In Australia, the highest fatal and non-fatal drowning rates occur in children under five years of age. To date, little qualitative research has been conducted on non-fatal drowning, with causal factor analysis generally conducted using coronial and hospital data. This study’s aim was to identify causal factors in hospital treated cases of non-fatal drowning in children as qualitatively self-reported by parents and caregivers. Cases of unintentional child (0–16 years) non-fatal drowning admissions and Emergency Department presentations to three tertiary care paediatric hospitals in New South Wales, Australia were identified via International Classification of Diseases (ICD) coding. Parents and caregivers of drowning patients were invited to participate in a semi-structured interview. Data were thematically coded using an inductive approach, with a focus on causal factors and recommendations for preventive approaches. Of 169 incidents, 86 parents/caregivers were interviewed. Children hospitalised for drowning were more often male (59.3%), aged 0–4 years (79.1%) and 30.2% were from household who spoke a language other than English. Qualitative incident descriptions were coded to five themes: lapse of supervision, unintended access (commonly in home swimming pools), brief immersion (usually young children bathing), falls into water and ongoing impacts. Drowning prevention recommendations were grouped under supervision, pool barriers and maintenance, cardiopulmonary resuscitation (CPR) training and emergency response, drowning is quick and silent, and learning swimming. Parents and caregivers of young children require ongoing education regarding supervision distractions and pool barrier compliance. Additional challenges are faced by those in rental properties with pools, parents/caregivers who cannot swim, and parents/caregivers from culturally and linguistically diverse backgrounds. Affordable, accessible, and culturally appropriate swimming lessons, water safety education and CPR training should be made more available for adult caregivers, particularly in languages other than English

Measuring Australian Children’s Water Safety Knowledge: The National Water Safety Quiz

Water safety knowledge levels of Australian children are poorly understood. Royal Life Saving developed an online National Water Safety Quiz (NWSQ) as an interactive means of determining water safety knowledge amongst Australian primary school children (ages 5 to 12 years). Over a period of 8 months, a total of 4,215 children participated in the NWSQ. The NWSQ identified areas of water safety where knowledge was poor including the topics of CPR, swimming, and river safety. Children achieved a better result as they aged. Females out-performed males overall and specifically from ages 10-12 years. Children from independent schools performed better. This research is the first of its kind to measure water safety knowledge at a population level for primary school children, using an online web-based tool. Understanding children’s water safety knowledge is important as it enables the tailoring, delivery and evaluation of programs which help to reduce the burden of drowning

Exploring the burden of fatal drowning and data characteristics in three high income countries: Australia, Canada and New Zealand

Background: Drowning is a leading and preventable cause of death that has suffered an attention deficit. Improving drowning data in countries would assist the understanding of the full extent and circumstances of drowning, to target interventions and evaluate their effectiveness. The World Health Organization identifies data collection as a key strategy underpinning effective interventions. This study compares unintentional fatal drowning data collection, management and comparison using the databases of Australia, Canada and New Zealand. Methods: Cases of fatal unintentional drowning between 1-January-2005 and 31-December-2014 were extracted. Cases were combined into a single dataset and univariate and chi square analysis (p < 0.01) were undertaken. Location and activity variables were mapped and combined. Variables consistently collected across the three countries were compared to the ILCOR Drowning Data Guideline. The authors also recommend variables for a minimum core dataset. Results: Of 55 total variables, 19 were consistent and 13 could be compared across the three databases. When mapped against the ILCOR Drowning Data Guideline, six variables were consistently collected by all countries, with five compared within this study. The authors recommend a minimum core dataset of 11 variables including age, sex, location, activity, date of incident, and alcohol and drug involvement). There were 8176 drowning deaths (Australia 34.1%, Canada 55.9%, New Zealand 9.9%). All countries achieved reductions in crude drowning rates (Australia - 10.2%, Canada - 20.4%, New Zealand - 24.7%). Location and activity prior to drowning differed significantly across the three countries. Beaches (X2 = 1151.0;p < 0.001) and ocean/harbour locations (X2 = 300.5;p < 0.001) were common in Australia and New Zealand, while lakes/ponds (X2 = 826.5;p < 0.001) and bathtubs (X2 = 27.7;p < 0.001) were common drowning locations in Canada. Boating prior to drowning was common in Canada (X2 = 66.3;p < 0.001). Conclusions: The comparison of data across the three countries was complex. Work was required to merge categories within the 20% of variables collected that were comparable, thus reducing the fidelity of data available. Data sources, collection and coding varied by country, with the widest diversity seen in location and activity variables. This study highlights the need for universally agreed and consistently applied categories and definitions to allow for global comparisons and proposes a core minimum dataset

Drowning of Pet Owners during Attempted Animal Rescues: The AVIR-A Syndrome

The rescuer who drowns can result from the attempted rescue of a human or an animal. We report here a total population analysis of all drowning fatalities for the 14-year period 1–July-2002 to 30-June-2016 which involved an attempted rescue of an animal. Cases were drawn from the Royal Life Saving National Fatal Drowning Database, which in turn, derived its data primarily from the National Coronial Information System (NCIS). Eight people drowned, all adults (ranging in age from 19-74 years), in the attempted rescue of an animal. Seven of the animals were domestic pet dogs, and in two cases farm animals. Six of the eight fatalities occurred in inland waterways. The AVIR-A syndrome, the ‘Aquatic Victim Instead of Rescuer– Animal’ (AVIR-A) drowning syndrome, is a subset of the AVIR drowning syndrome. Environmental design and regulation are unlikely to prevent this type of fatality. Public awareness, with emphasis on non-contact rescue training should be the approach taken

Developing drowning prevention strategies for rivers through the use of a modified Delphi process

Introduction Internationally, rivers are a leading drowning location, yet little evidence exists evaluating river drowning prevention strategies. This study aims to use expert opinion to identify strategies more likely to be effective. Methods Using a modified Delphi process, a virtual panel of 30 experts from 12 countries considered, grouped and prioritised strategies for river drowning prevention. Proposed strategies were assessed against known evidence and suitability in high-income countries (HICs) as well as low-income and middle-income countries (LMICs) using expert opinion. The final phase consolidated a list of strategies whose effectiveness was assessed against 10 evidence-based river drowning scenarios. Results An initial list of 424 prevention strategies was refined to 22. After being assessed against the 10 scenarios, a final list of 13 strategies was derived. Strategies addressed alcohol consumption around rivers, flood mitigation, improving child supervision, learning to swim, increased lifejacket wear and achieving community-wide resuscitation skills. Discussion While all 13 strategies were assessed as being effective in both LMICs and HICs by at least 60% of the respondents, further work is required to define river drowning at a country level and therefore allow for effective solutions to be developed, particularly in LMICs. No strategy will be effective in isolation and must be implemented alongside policy and behaviour change, public awareness and education. Evaluation should be incorporated as part of any future implementation of strategies. Conclusion This Delphi process identified 13 drowning prevention strategies for rivers. Further research is required to validate the efficacy of these findings through implementation and evaluation
