Lessons learned through the 20-year development of a national fatal drowning database in Australia.

BACKGROUND: Co-ordinated, evidence-based policy and programmatic efforts are needed to respond to complex drowning prevention problems. Comprehensive, current, and robust data are vital for agenda setting, burden and risk factor identification, intervention design and evaluation, as well as setting policy. We aim to record methods used in, and identify impacts of, the development of a national fatal drowning database (NFDD) in Australia, including lessons learned across research, policy, and practice. METHODS: We employ a case study method using process mapping and document review to explore the evolution, drivers and impacts of the NFDD. We analyse methodological approaches including those relating to data definitions, drowning case collection, and management, as well as tracking the various outputs of the NFDD. We describe a development timeline that presents impact of drowning prevention policy, and research agendas on database development, and research investments more specifically. RESULTS: Our study identified that the collected variables grew 20-fold from 2002 to 2022, reaching 259 variables, and 5,692 unique cases of fatal drowning. The NFDD employs data triangulation methodology, combining keyword and targeted searches of coronial files, media report monitoring, and organisational data provision. Database development is influenced by the Australia Water Safety Strategy, policymaker and practitioner-initiated research agendas, and identification of knowledge gaps. We identified numerous outputs spanning publications, media, intervention development, and legislative submissions. CONCLUSION: A comprehensive and robust NFDD informed by policymaker and practitioner input can enhance surveillance, policy, and intervention development for drowning prevention. Employing mixed data collection and validation methods can supplement weaknesses in official data sources. There is a need for the NFDD to continue to evolve in its application while maintaining rigorous case identification and data quality assurance processes. Despite significant investment, the outputs and influence on drowning prevention practice in Australia has been extremely valuable and contributed to sizeable reductions in Australia's fatal drowning rate.

The characteristics of drowning among different types of international visitors to Australia and how this contributes to their drowning risk.

OBJECTIVE: Australia is a popular destination for international visitors. This study reviews international visitor drowning deaths in Australia and analyses drowning by visitor type. METHODS: A total population retrospective study exploring drowning deaths of international visitors was conducted between 2008 and 2018. Data were extracted from the Royal Life Saving National Fatal Drowning Database and categorised into four subgroups: overseas tourists, international students, working holiday makers and work-related visitors. Descriptive statistics, non-parametric tests and relative risk (RR) were calculated. RESULTS: In total, 201 international visitors drowned in Australia, 7% of all drowning deaths; a crude drowning rate of 0.27/100,000 visitors versus 0.95/100,000 for residents (RR=0.19 [95% CI: 0.16-0.22]). Most deaths were males (79%) and people aged 18-34 years (50%). Visitors frequently drowned at beaches (33%), and when swimming (41%). Thirty-five percent recorded a pre-existing medical condition. Overseas tourists on holiday were the most likely to drown compared to other subgroups. CONCLUSION: International visitors represent a small but increasing proportion of people drowning in Australia. The circumstances of which visitors drown vary by travel purpose, age, country of origin, location of drowning and activity. IMPLICATIONS FOR PUBLIC HEALTH: International visitors have unique safety needs, requiring tailored prevention based on the purpose of travel and country of origin.

Epidemiology of unintentional fatal drowning among migrants in Australia.

OBJECTIVE: This study aimed to describe the epidemiology and risk factors contributing to drowning among migrants in Australia. METHODS: A total population retrospective epidemiological study of unintentional drowning deaths in Australia between 1 July 2009 and 30 June 2019 of people born outside Australia (migrants). Cases were extracted from the National Coronial Information System. Descriptive statistics, chi-square and relative risk were calculated. Crude drowning rates were based on country of birth and population in Australia. RESULTS: There were 572 migrant deaths over the study period, 28.9% of total drowning deaths, 82.9% were male. Twenty-one per cent were aged 25-34 years and 40.8% had lived in Australia for 20+ years. Migrants at highest risk of drowning were from: South Korea (2.63/100,000 95%CI: 0.85-8.25), Taiwan (2.29/100,000 95%CI: 0.27-13.44), and Nepal (2.15/100,000 95%CI: 0.23-11.55). Migrants were more likely to drown when around rocks (p<0.001) compared with Australian-born people, who most frequently drowned in rivers (p<0.001). CONCLUSIONS: Migrants are not over-represented in drowning statistics. However, unique trends were found for drowning among migrants based on country of birth and length of time in Australia. Implications for public health: Holistic drowning prevention strategies and policies are required to effectively lower drowning risk among migrant communities.

Reducing inequities among adult female migrants at higher risk for drowning in Australia: The value of swimming and water safety programs.

ISSUE ADDRESSED: Drowning is a global public health challenge with a need to ensure equity to drowning prevention information and interventions. In Australia, people born overseas are identified as being at greater risk of drowning. This paper presents findings from a community-based qualitative evaluation of swimming and water safety (SWS) programs delivered to adults from migrant backgrounds in Sydney, Australia. METHODS: A qualitative study was conducted in November-December 2019 among 35 female participants of SWS programs targeted to adult migrants. While offered to all SWS program participants, no males took part in the study. Focus groups and interviews were recorded, transcribed and thematically analysed using a deductive approach. The domains of enquiry were guided by the health belief model and the theory of planned behaviour. RESULTS: Study participants were ≥25 years, first generation and most had lived in Australia for ≥10 years. Most were nonswimmers and were fearful of water prior to the program. Key themes were: direct SWS program outcomes, health and well-being; enablers and barriers to participation including: motivation, a program coordinator, fear and settlement priorities. CONCLUSION: Findings suggest that in order to increase SWS participation among migrant communities, the broader determinants of health need to be considered. Culturally appropriate strategies are required to enable both men and women equal opportunities to access SWS programs. SO WHAT: SWS programs provide multiple benefits for adult migrants; however, the impact on reducing inequities is limited, with broader multi-strategic health promotion approaches and policies required for inclusion and sustainability.

Exploring children's participation in commercial swimming lessons through the social determinants of health.

ISSUE ADDRESSED: Drowning is a public health challenge, disproportionately impacting children. Social determinants of health (SDH) such as socio-economic disadvantage and geographic isolation increase drowning risk. Swimming and water safety lessons, in part, have reduced drowning in children, while also enabling healthy aquatic participation. Research suggests that some Australian children receive insufficient swimming and water safety education and are not achieving essential skills. METHODS: A cross-sectional retrospective analysis of swimming and water safety skills achieved by a cohort of children (5-12 years) attending commercial swimming lessons in three Australian states was undertaken. Variables included participant demographics (age, gender, and the SDH of socio-economic status [SES], and geographical remoteness) and skills being taught and achieved. Skills achieved were analysed against the National Swimming & Water Safety Framework and the National Benchmark. RESULTS: Swim schools were more likely to teach freestyle (87%) and backstroke (83%); and less likely to teach water safety skills like treading water (53%), and survival backstroke (46%). Overall, 40% of 12-year-old children failed to achieve the National Benchmark of 50 metres freestyle, fewer were achieving minimum water safety skills. Children from low socio-economic areas and regional locations were less likely to be achieving 50 metres freestyle. Children in this study were commonly from major cities (94%) and of high socio-economic areas (53%). CONCLUSIONS: Swimming lessons must incorporate a broad range of swimming and water safety competencies to ensure children have the skills required to reduce drowning, especially for those deemed at increased risk. SO WHAT: Stakeholders must prioritise holistic drowning prevention education strategies, ensuring all children can access swimming and water safety programs regardless of their socio-economic status or geographical location.

Comparing rivers to lakes: Implications for drowning prevention.

OBJECTIVE: To contrast unintentional fatal drowning in rivers with lakes to determine appropriateness for application of existing river drowning prevention strategies. DESIGN: A total population retrospective cross-sectional analysis using coronial data. SETTING: Australia, 1 July 2013 to 30 June 2018. PARTICIPANTS: Children and adults (n = 342) who died from unintentional drowning in a river or lake. MAIN OUTCOME MEASURES: Incidence, crude fatality rates, relative risk (95% confidence interval) and chi-square tests of independence for risk factors for unintentional fatal drowning. Subset analysis of land management for lake drowning locations. RESULTS: Four-fifths (82%) occurred in rivers. Lake drowning was more likely among 0- to 17-year-olds, Aboriginal and Torres Strait Islander people and when swimming or using watercraft. River drowning most commonly occurred following a fall into water and with alcohol involvement. Drowning risk in very remote areas was elevated for both lakes (relative risk = 18.34; 95% confidence interval: 1.61-209.44) and rivers (relative risk = 15.89; 95% confidence interval: 5.56-45.37) compared to major cities. Those responsible for land and water management at lakes were primarily local government (59%), water authorities (32%) and parks and wildlife authorities (7%). CONCLUSIONS: In contrast to a focus on adults and alcohol in existing river drowning prevention strategies, lake interventions must target children, Aboriginal and Torres Strait Islander peoples and recreational lake users. Fatal drowning rates are high for remote rivers and lakes, necessitating focused effort. There are opportunities to embed drowning prevention strategies within land and water management plans. Lake drowning prevention requires broader engagement with land and water managers and Aboriginal and Torres Strait Islander peoples.

Autism spectrum disorder and unintentional fatal drowning of children and adolescents in Australia: an epidemiological analysis.

OBJECTIVES: This study explored unintentional fatal drowning among children and adolescents (0-19 years) diagnosed with autism spectrum disorder (ASD) in Australia. DESIGN: This total population, cross-sectional audit used data from the Royal Life Saving National Fatal Drowning Database to explore demographic and causal factors in ASD drowning cases between 1 July 2002 and 30 June 2018. Rates and relative risk (RR) with a 95% confidence interval (CI) were calculated for drowning cases with and without ASD, using estimated population-level prevalence data. RESULTS: Of the 667 cases of drowning among 0-19 year olds with known medical history, 27 children and adolescents (4.0%) who drowned had an ASD diagnosis. Children and adolescents with ASD were three times more likely to drown than those without ASD (RR=2.85; CI 0.61 to 13.24). Among those with ASD, 0-4 year olds record the highest rate (11.60/100 000 diagnosed). Children and adolescents with ASD were significantly more likely to drown when compared with those without ASD: if aged 5-9 years (44.4% of ASD-yes cases; 13.3% of ASD-no cases); in a lake or dam (25.9% vs 10.0%) and during winter (37.0% vs 13.1%). CONCLUSION: Heightened awareness of drowning risk for children and adolescents with ASD is required, including adult supervision and barriers restricting water access. Further evaluation of the effectiveness of personal alarms to alert caregivers to an unsupervised child is warranted. Challenges exist regarding accurate estimates of population-level ASD prevalence and identification of ASD in coronial files. As the diagnosis of ASD does not often occur until age five, results may be an underestimate.

Identifying a gap in drowning prevention: high-risk populations.

INTRODUCTION: Some populations have been less susceptible to reductions in drowning than others. It has been hypothesised that this is due to prevention strategies failing to account for the influence of social determinants (such as ethnicity, socioeconomic status). Populations such as ethnic minorities have been over-represented in injury statistics, however this is not well explored in drowning. This study aims to identify high-risk populations for drowning, risk factors and prevention strategies. METHODS: A literature review undertaken systematically using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach was conducted of peer-reviewed literature in English, published between 1990 and 2018 from high-income countries. Search terms included drowning, water safety, ethnic minority, migrant, and culturally diverse. RESULTS: In total, 35 articles were included. High-risk populations identified were: ethnic minorities, First Nations/Aboriginal people, migrants and rural residents. Over half (51%) focused on children (0-18 years). Risk factors included social determinants, swimming ability and knowledge, attitudes and behaviour. Four intervention studies were found; two focused on upskilling adults from high-risk populations to increase employment opportunities within the aquatic industry; an evaluation of a 10-year rock fishing safety education project and a learn-to-swim programme for minority children. Proposed prevention strategies included education, practical skills, research, policy and engagement. DISCUSSION: Limited literature exists pertaining to drowning among adults from high-risk populations. There is a need to increase the sophistication of drowning prevention strategies addressing the disparities in drowning from a culturally appropriate perspective. Acknowledging the role of the social determinants of health in drowning prevention is essential in order to improve drowning outcomes for high-risk populations globally.

Media reporting of summer drowning: A partial picture, useful for advocacy.

ISSUE ADDRESSED: Media reporting of drowning deaths can be used for multiple purposes, including advocacy, enhancing data on drowning and supporting policy development. Accurate, current and comprehensive data help ensure the development of effective prevention programs as well as being a tool for advocacy. Advocacy for drowning prevention through the media can create behaviour change aligned to the Health Belief Model (HBM). METHODS: This study compares media reports of fatal unintentional drowning across the 2017/18 Australian summer (1-December-2017 to 28-February-2018) with drowning cases in the National Coronial Information System (NCIS). RESULTS: Media monitoring identified 84 cases, of which nine (11%), were deaths but not drowning. There were 104 NCIS deaths during this time of which 75 were reported in the media (72% capture). Media captured 100% of drowning incidents involving people 0-24 years and in ocean/harbour locations. Drowning incidents among older people (75+ years; 36% capture), in bathtubs (0% capture), swimming pools (33% capture) and with an unknown activity (27% capture) were poorly reported. CONCLUSIONS: Where there are a lack of timely data on drowning, the use of media can help capture deaths, with limitations. Transmission of messages about drowning risk factors and prevention strategies, during summer, may lead to behaviour change at a time when drowning risk is highest. SO WHAT?: Working with the media to help enhance advocacy efforts, in particular the development and use of effective drowning prevention messages, is key to informing the public about risk factors in the HBM to achieve behaviour change.

Boating-related drowning in Australia: Epidemiology, risk factors and the regulatory environment.

OBJECTIVE: Recreational boating is a popular pastime in many high income countries, and is a leading activity prior to drowning. This study reports on unintentional fatal drowning associated with boating-related incidents in Australia. METHODS: A total population, retrospective, cross sectional design examined all boating-related unintentional drowning deaths between July 1, 2005 and June 30, 2015. Variables examined included age, sex, location of drowning incident, vessel type, activity, presence of alcohol/drugs, and lifejacket wear. Relative risk (with a 95% confidence interval) was calculated using fatal drowning rates per 100,000 population and rates per 100,000 registered vessels. Chi square analysis and non-parametric tests for significance were applied. Statistical significance was deemed p < .05. RESULTS: A total of 415 people drowned while boating during the study period, 91.8% male and 35.7% aged between 25 and 44 years. Men were 10 times more likely to drown when boating than females (RR = 10.64 CI:7.55-14.97). Over one-quarter (28.7%) of incidents involved alcohol, in 30.6% drugs were identified (31.3% were illegal) and 90.4% were not wearing a lifejacket. Children were more at risk of drowning on a houseboat than adults (RR = 7.13; CI:1.61-31.61). Females were more likely to drown than males when using a personal watercraft (RR = 10.53; CI:2.75-40.33). CONCLUSION: Boaters may be taking unnecessary risks by disregarding safety regulations, such as not wearing lifejackets and substance use (such as alcohol and illegal drugs). Boating in remote locations presents a high risk of drowning. While safety regulations are in place, enforcement and behavior change remain challenges. Practical application: Findings support recommendations for increased enforcement of alcohol-related regulations and introducing drug-testing for boaters. Consistency of boating safety regulations, especially around lifejacket wear, is recommended to influence behavior change. The effectiveness of current lifejacket regulations need to be critically evaluated in the context of increasing wear rates for adults and children.

Perceptions of the risk of drowning at surf beaches among New Zealand youth.

In many countries, beaches are a high-risk location for drowning. In New Zealand, youth and young adults are particularly at risk of drowning at beaches, accounting for 17.4% of drowning deaths and 18.4% of rescues at surf beaches between 2008 and 2013, over 90% of fatalities were male. This study explored New Zealand youth risk perceptions of drowning and their coping appraisal processes at a surf beach. A cross-sectional survey of high school students (n = 599) was conducted between February and April 2014. Females and non-New Zealand European students reported higher levels of perceived vulnerability and severity of drowning risk, and New Zealand European students reported higher levels of self-efficacy of preventive actions. By addressing the underlying causes of underestimation of risk and overestimation of ability, these findings can be utilized to increase awareness and to enhance water safety risk strategies for youth, especially males, in the surf beach setting.
