Rate of Aquatic and Maritime Drowning Deaths After US-Mexico Border Wall Height Increase.

This study assesses migratory drowning deaths along the southwest border of the US before and after the increase in border wall height.

The effect of the 'Swim Reaper' program on water safety awareness, drowning mortality and morbidity among males aged 15-34 years in Aotearoa, New Zealand.

BACKGROUND AND OBJECTIVE: To increase water safety awareness among young males New Zealand introduced the Swim Reaper program in 2016. The program ran annually over summer and in 2018/19 an evaluation was conducted. The objective of this study was to evaluate the impact of the 2018/19 Swim Reaper social media-based campaign on self-reported water safety awareness and identify changes in fatal and nonfatal drowning rates for New Zealand resident males aged 15-34 years before and after the 2016 Swim Reaper program. METHODS: Online surveys pre (December-2018) and post (February-March-2019) Swim Reaper campaign were used to estimate water safety awareness post-campaign relative to pre-campaign using negative binomial regression adjusted for potential confounders. Interrupted time series (ITS) analysis, adjusted for seasonality, explored changes in drowning mortality, hospital admissions and Accident Compensation Corporation (ACC) claims pre and post program introduction (2016). RESULTS: A total of 518 males responded (50.6% post-campaign). There were significant improvements (post vs. pre-campaign) in self-reported water safety awareness. ITS analysis showed a reduction in drowning related hospital admissions post relative to pre-program (RR = 0.47; [95%CI: 0.24-0.90]; p = 0.02). DISCUSSION: Young males are an at-risk cohort for drowning and creating behavior change among this group can be challenging. Using a unique, humor-based approach the Swim Reaper program appears to be having some impact on self-reported water safety behaviors, as well as unintentional drowning-related hospitalization rates. Further evaluation, more clearly linked to campaign themes, is required to ascertain direct impact of the program. CONCLUSION: The novelty and reach of the campaign within the context of a prevailing downward trend in drownings may provide support for social media-based programs targeting this hard-to-reach demographic.

The burden, risk factors and prevention strategies for drowning in Türkiye: a systematic literature review.

INTRODUCTION: Drowning is a public health problem in Türkiye, as in the rest of the world. This study aims to systematically review the literature on drowning in Türkiye with a focus on data sources, epidemiology, risk factors and prevention strategies. METHODS: Literature searches were conducted using PubMed, SPORTSDiscus, Scopus, Web of Science, Turk MEDLINE, Google Scholar and Google Akademik (Turkish language). Studies (limited to original research written in English and Turkish) reporting drowning (unintentional and intentional; fatal and non-fatal) of residents and tourists in Türkiye were independently dual screened at the title and abstract and full text stages. Study quality was assessed using JBI checklists and evidence level assessed based on study design. RESULTS: From a total of 917 studies, 49 met the inclusion criteria. Most (51%) focused on unintentional fatal drowning. Included studies were most commonly analytical cross-sectional studies (n = 23) and case series (n = 20) meaning the evidence level was low or very low for 48 (98%) studies. Fifteen studies examined drowning at the national level, while sub-national studies (n = 30) focused on urban areas across three provinces: Antalya (n = 6), Istanbul (n = 6), Izmir (n = 4). There was little consensus on risk factors beyond male drowning risk, and no data reported on implemented or evaluated drowning prevention interventions. DISCUSSION: There is a need for more national-level studies to identify the causes of drowning and to guide intervention implementation and evaluation to inform policy makers and donors. Currently official data is limited in its detail, providing age and gender data only, hampering efforts to identify, and thus address, causal factors for drowning. PRACTICAL APPLICATIONS: There is currently very little evidence to inform investment in effective drowning prevention interventions in Türkiye. To improve this, data collection systems on drowning in Türkiye need to be strengthened via the development a national drowning registry. TRIAL REGISTRATION: #CRD42022382615.

Examining the relationship between heatwaves and fatal drowning: a case study from Queensland, Australia.

BACKGROUND: Globally, drowning is a leading cause of injury-related harm, which is heavily impacted by environmental conditions. In Australia, fatal unintentional drowning peaks in summer, yet the impact of prolonged periods of hot weather (heatwave) on fatal drowning has not previously been explored. METHODS: Using a case-crossover approach, we examined the difference in drowning risk between heatwave and non-heatwave days for the Australian state of Queensland from 2010 to 2019. Heatwave data, measured by the excess heat factor, were acquired from the Bureau of Meteorology. Incidence rate ratios (IRRs) were calculated by sex, age of drowning decedent, category of drowning incident (International Classification of Diseases-10 codes) and heatwave severity. Excess drowning mortality during heatwaves was also calculated. RESULTS: Analyses reveal increased fatal drowning risk during heatwave for males (IRR 1.22, 95% CI 0.92 to 1.61), people aged 65+ years (IRR 1.36, 95% CI 0.83 to 2.24), unintentional drowning (IRR 1.28, 95% CI 0.98 to 1.69) and during severe heatwaves (IRR 1.26, 95% CI0.88 to 1.82). There were 13 excess drowning deaths due to heatwave over the study period. DISCUSSION: The findings confirm an increased risk of fatal drowning during heatwaves. With increased likelihood and severity of heatwaves, this information should be used to inform drowning prevention, in particular the timing of public awareness campaigns and patrolling of supervised aquatic locations. CONCLUSIONS: Water safety and patrolling organisations, as well as first responders, need to prepare for more drowning deaths during heatwave conditions. In addition, drowning prevention education ahead of heatwaves is needed for recreational swimmers, and older people, particularly those with comorbidities which may be further exacerbated by a heatwave.

The burden of attempted hanging and drowning presenting to hospitals in Ireland between 2007 and 2019: a national registry-based study.

PURPOSE: To measure the impact of hospital-treated self-harm by hanging and drowning in Ireland in 2007-2019 and identify risk factors for these methods of self-harm. METHOD: Data on all self-harm presentations to Irish hospitals between 2007 and 2019 were obtained from the National Self-Harm Registry Ireland, a national self-harm surveillance system. Multinomial regression was used to explore factors associated with attempted hanging and drowning. RESULTS: The age-standardised incidence rate of attempted hanging and drowning increased by 126% and 45%, respectively, between 2007 and 2019. The incidence of both methods was highest among young people aged 15-24 years. The odds of presenting to hospital for attempted hanging were highest in males (aOR 2.85, 95% CI 2.72-3.00), people experiencing homelessness (aOR 1.32, 95% CI 1.16-1.49) and individuals living in the capital, Dublin (aOR 1.23, 95% CI 1.17-1.29). The odds of presenting for attempted drowning were highest in males (aOR 1.68, 95% CI 1.58-1.78) and people experiencing homelessness (aOR 2.69, 95% CI 2.41-2.99). CONCLUSION: The incidence of hospital-treated self-harm by hanging and drowning is increasing in Ireland and is highest among adolescents and young adults. Males and people experiencing homelessness may be at highest risk and warrant targeted preventive interventions.

Submersion Injuries and the Cost of Injury Associated with Drowning Events in the United States, 2006-2015.

INTRODUCTION: The World Health Organization has reported submersion injuries as the third most common cause of death due to unintentional injury in the world. Greater detail in the rates, risk factors, and healthcare associated costs of submersion injuries could be instrumental in demonstrating the need for further funding and intervention. METHODS: The study was a cross-sectional analysis of a nationally representative dataset of inpatient and emergency department (ED) encounters between 2006 and 2015 in the United States (US). Healthcare utilization costs were provided within the datasets and adjusted to reflect actual charges and provider fees. Lastly, the final cost values were adjusted to the 2020 US dollar (USD) and summarized using a log adjusted mean. RESULTS: On average, there were 11,873 submersion injuries per year that presented to the ED in the US. Resulting in a rate where approximately 9 out of every 100,000 ED visits were associated with a submersion injury. Slightly more than 6% died in the ED, 24.2% were admitted, and 69.3% were discharged from the ED. In total, annual cost of submersion injuries in the US for ED care is approximately $12.5 million, inpatient care is approximately $27.5 million, and total annual healthcare cost exceeds $40 million. DISCUSSION: While these results only represent a fraction of the total cost associated with submersion injuries, it remains substantial and unchanged over the 10-year study period. Certain demographic groups showed higher rates of injury and disease burden, thus bearing a greater amount of the cost.

Drowning rates among children and adolescents (aged 7-17) in Israel during the years 2008-2018.

OBJECTIVE: Drowning is one of the leading causes of death among children and youth worldwide. This study aims to examine differences in the rates of drowning (fatal and non-fatal drowning) among children and youth in Israel stratified by age, sex, sector, place of drowning, and the drowning outcome. In addition, we compared the results of studies reported in other countries in specific age groups based on statistics of about 100,000 drowning cases. METHOD: A statistical analysis of 474 drownings between 2008 and 2018 was conducted. All cases refer to youngsters aged 7-17 in the State of Israel. Statistical analysis was performed on data obtained from the Beterem - Safe Kids Israel organization and from the Israel Central Bureau of Statistics. Disparities between groups within the examined population were analyzed based on gender, sector (Jewish versus non-Jewish), and drowning site. RESULTS: Of the 474 drownings that occurred during 2008-2018, 38.4% ended in death. 79% of the cases occurred in pools. The Arab minority sector (21.1% of the general population) accounted for 25.1% of all drownings, males accounted for 70.5% of the drowning cases, and the age group with the most drownings (48.5%) was that of 15-17 years. The Jewish population was involved in more than 75% of drownings in places designated for bathing and in more than 83% of all disaster scenarios, whereas the Arab minority was involved in more than 61% of drownings in places not designated for bathing. CONCLUSIONS: The results are comparable to those of other studies worldwide. Boys drown twice as much as girls, mainly in the age group of 15-17. This may be explained by overconfidence in boys and a tendency to overestimate their actual swimming abilities. Most drownings occur in pools. Drowning among the Jewish population occurs mainly in designated bathing sites. PRACTICAL APPLICATIONS: The findings can and, in fact, must be used to inform and educate the younger generation as to the potential dangers involving bathing in designated bathing sites.

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 Combined Effects of Short-Term Exposure to Multiple Meteorological Factors on Unintentional Drowning Mortality: Large Case-Crossover Study.

BACKGROUND: Drowning is a serious public health problem worldwide. Previous epidemiological studies on the association between meteorological factors and drowning mainly focused on individual weather factors, and the combined effect of mixed exposure to multiple meteorological factors on drowning is unclear. OBJECTIVE: We aimed to investigate the combined effects of multiple meteorological factors on unintentional drowning mortality in China and to identify the important meteorological factors contributing to drowning mortality. METHODS: Unintentional drowning death data (based on International Classification of Diseases, 10th Edition, codes W65-74) from January 1, 2013, to December 31, 2018, were collected from the Disease Surveillance Points System for Guangdong, Hunan, Zhejiang, Yunnan, and Jilin Provinces, China. Daily meteorological data, including daily mean temperature, relative humidity, sunlight duration, and rainfall in the same period were obtained from the Chinese Academy of Meteorological Science Data Center. We constructed a time-stratified case-crossover design and applied a generalized additive model to examine the effect of individual weather factors on drowning mortality, and then used quantile g-computation to estimate the joint effect of the mixed exposure to meteorological factors. RESULTS: A total of 46,179 drowning deaths were reported in the 5 provinces in China from 2013 to 2018. In an effect analysis of individual exposure, we observed a positive effect for sunlight duration, a negative effect for relative humidity, and U-shaped associations for temperature and rainfall with drowning mortality. In a joint effect analysis of the above 4 meteorological factors, a 2.99% (95% CI 0.26%-5.80%) increase in drowning mortality was observed per quartile rise in exposure mixture. For the total population, sunlight duration was the most important weather factor for drowning mortality, with a 93.1% positive contribution to the overall effects, while rainfall was mainly a negative factor for drowning deaths (90.5%) and temperature and relative humidity contributed 6.9% and -9.5% to the overall effects, respectively. CONCLUSIONS: This study found that mixed exposure to temperature, relative humidity, sunlight duration, and rainfall was positively associated with drowning mortality and that sunlight duration, rather than temperature, may be the most important meteorological factor for drowning mortality. These findings imply that it is necessary to incorporate sunshine hours and temperature into early warning systems for drowning prevention in the future.

Epidemiology, clinical aspects, and management of pediatric drowning.

Drowning is the third leading cause of injury death in the pediatric population worldwide, with incidence peaking among those aged 1-4 years and again in adolescence.The purpose of this commentary is to review the basic pathophysiology of drowninginjury and factors that affect the outcome, such as submersion and hypothermia. We also discuss principles of prehospital and in-hospital management, comprising resuscitation and stabilization, administration of oxygen and intravenous liquids, and central reheating.Even though the mortality rate has decreased in recent years, further investments and safety measures are needed to prevent child drowning deaths.

Drowning in Children and Predictive Parameters: A 15-Year Multicenter Retrospective Analysis.

BACKGROUND: Drowning is a serious and underestimated public health problem, with the highest morbidity and mortality reported among children. Data regarding pediatric outcomes of drowning are often inadequate, and data collection is poorly standardized among centers. This study aims to provide an overview of a drowning pediatric population in pediatric emergency department, focusing on its main characteristics and management and evaluating prognostic factors. METHODS: This is a retrospective multicenter study involving eight Italian Pediatric Emergency Departments. Data about patients between 0 to 16 years of age who drowned between 2006 and 2021 were collected and analyzed according to the Utstein-style guidelines for drowning. RESULTS: One hundred thirty-five patients (60.9% males, median age at the event 5; interquartile range, 3-10) were recruited and only those with known outcome were retained for the analysis (133). Nearly 10% had a preexisting medical conditions with epilepsy being the most common comorbidity. One third were hospitalized in the intensive care unit (ICU) and younger males had a higher rate of ICU admission than female peers. Thirty-five patients (26.3%) were hospitalized in a medical ward while 19 (14.3%) were discharged from the emergency department and 11 (8.3%) were discharged after a brief medical observation less than 24 hours. Six patients died (4.5%). Medium stay in the ED was approximately 40 hours. No difference in terms of ICU admission was found between cardiopulmonary resuscitation performed by bystanders or trained medical personnel ( P = 0.388 vs 0.390). CONCLUSIONS: This study offers several perspectives on ED victims who drowned. One of the major finding is that no difference in outcomes was seen in patients who received cardiopulmonary resuscitation performed by bystanders or medical services, highlighting the importance of a prompt intervention.

Buckets associated home drowning in Indian infants and toddlers: An analysis of 18 fatalities from 2016-2022.

Cases of drowning at home of unsupervised infants and toddlers in buckets have been reported elsewhere but little research on this largely preventable death in India exists. We performed a descriptive analysis on the basis of Google search of published news report in leading Indian newspapers or news channels. Data were collected employing a pre-determined tool. Between April 2016 and March 2022, we found 18 such cases. The large majority were between 12 and 18 months of age (12/18). This little recognized source of unintentional injury is eminently avoidable, necessitating both public and parental attention and awareness.

The epidemiology, risk factors and impact of exposure on unintentional surfer and bodyboarder deaths.

Surfing and bodyboarding (SAB) are popular activities, but not without risk. Limited SAB mortality and exposure risk explorations exist, so this cross-sectional study explores epidemiology and risk factors for SAB deaths (1 July, 2004-30 June,2020) in Australia: including decedent and incident profiles, causes of death, differences between fatalities during SAB and other coastal activities; and the impact of exposure on SAB mortality risk. Fatality data were sourced from the National Coronial Information System, incident and media reports. Tide-state data, population data and participation data were sourced from relevant authorities. Analyses included chi-square testing and simple logistic regression with odds ratios. There were 155 SAB deaths (80.6% surfing; 96.1% male; 36.8% aged 55+years; 0.04/100,000 residents; 0.63/100,000 surfers). Drowning was the most common cause of death (58.1%; n = 90), but higher in bodyboarding, with bodyboarders 4.62 times more likely to drown than surfers (95%CI: 1.66-12.82; p = 0.003). Almost half (44.5%; n = 69; χ22 = 9.802; p = 0.007) were with friends/family, and the largest proportion occurred during a rising tide (41.3%; n = 64; χ23 = 180.627; p<0.001) followed by a low tide (36.8%;n = 57). Australians surf 45.7 times each year, for 1.88 hours each visit equalling 86.1 'exposed' hours. With exposure-time considered, exposure-adjusted surfer mortality rate (0.06/1 million hours) is lower than other in-water activities (0.11/1 million hours). Younger surfers (14-34 years) surfed more yet had the lowest mortality rate (114.5 hours/year; 0.02/1 million hours). Older surfers (55+ years) had a lower SAB mortality rate (0.052) than the all-cause crude mortality rate of their average population counterparts (1.36). Cardiac conditions were identified in 32.9% (n = 69) of SAB deaths. SAB are relatively safe, with lower exposure mortality rates than other activities. Prevention should target older surfers, inland residents, and identification of surfers with risk factors for cardiac events.

Burden of fatal drowning in California, 2005-2019.

OBJECTIVE: To characterise risk factors for fatal drowning in California, USA to inform priorities for prevention, policy and research. METHODS: This retrospective population-based epidemiological review of death certificate data evaluated fatal drowning events in California from 2005 to 2019. Unintentional, intentional, and undetermined drowning deaths and rates were described by person (age, sex, race) and context-based variables (region and body of water). RESULTS: California's fatal drowning rate was 1.48 per 100 000 population (n=9237). Highest total fatal drowning rates occurred in the lower population density northern regions, among older adults (75-84 years: 2.54 per 100 000 population; 85+: 3.47 per 100 000 population) and non-Hispanic American Indian or Alaska Native persons (2.84 per 100 000 population). Male drowning deaths occurred at 2.7 times the rate of females; drowning deaths occurred mainly in swimming pools (27%), rivers/canals (22.4%) and coastal waters (20.2%). The intentional fatal drowning rate increased 89% during the study period. CONCLUSIONS: California's overall fatal drowning rate was similar to the rest of the USA but differed among subpopulations. These divergences from national data, along with regional differences in drowning population and context-related characteristics, underscore the need for state and regional level analyses to inform drowning prevention policy, programmes and research.

Drowning in the United States: Patient and scene characteristics using the novel CARES drowning variables.

INTRODUCTION: Drowning results in more than 360,000 deaths annually, making it the 3rd leading cause of unintentional injury death worldwide. Prior studies examining drowning internationally have reviewed factors surrounding drowning however in the U.S. limited data exists. This study evaluated the novel drowning elements collected in the Cardiac Arrest Registry to Enhance Survival (CARES) during the first 2 years of data collection. METHODS: A retrospective analysis of the CARES database identified cases of drowning etiology for the two years 2020 and 2021. Demographics and incident characteristics were collected. Characteristics included items such as body of water, precipitating event, and who extracted patients. Survival to hospital discharge and neurological outcomes were compared between groups based on who initiated CPR using Pearson's Chi-Squared tests. RESULTS: Among 1,767 drowning cases, 69.7% were male, 47.1% white and 11.9% survived to hospital discharge. Body of water was often natural body (36.2%) or swimming pool (25.9%) and bystanders removed the patient in 42.7% of incidents. Swimming was the most common activity at time of submersion (18.6%) however in 50.2% of cases, activity was unknown or missing. When compared to EMS/First Responder initiating CPR, odds of neurologically favorable survival were significantly higher in the Bystander initiated CPR group (OR = 2.85, 95% confidence interval [CI] 2.02-4.01). CONCLUSION: In this national cohort of drowning patients in cardiac arrest, the novel CARES drowning elements provide additional detail of epidemiological factors. Bystander CPR was associated with improved neurological outcomes. Future studies utilizing the drowning elements can inform injury prevention strategies.

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 and clinical characteristics of drowning patients presenting to a pediatric emergency department from 2017 to 2020.

BACKGROUND: Drowning is a common mechanism of injury in the pediatric population that often requires hospitalization. The primary objective of this study was to describe the epidemiology and clinical characteristics of pediatric drowning patients evaluated in a pediatric emergency department (PED), including the clinical interventions and outcomes of this patient population. METHODS: A retrospective cohort study was conducted of pediatric patients evaluated in a mid-Atlantic urban pediatric emergency department from January 2017 to December 2020 after a drowning event. RESULTS: Eighty patients ages 0-18 were identified, representing 57 79 unintentional events and 1 intentional self-injury event. The majority of patients (50%) were 1-4 years of age. The majority (65%) of patients 4 years of age or younger were White, whereas racial/ethnic minority patients accounted for the majority (73%) of patients 5 years of age or older. Most drowning events (74%) occurred in a pool, on Friday through Saturday (66%) and during the summer (73%). Oxygen was used in 54% of admitted patients and only in 9% of discharged patients. Cardiopulmonary resuscitation (CPR) was performed in 74% of admitted patients and 33% of discharged patients. CONCLUSIONS: Drowning can be an intentional or unintentional source of injury in pediatric patients. Among the patients who presented to the emergency department for drowning, more than half received CPR and/or were admitted, suggesting high acuity and severity of these events. In this study population, outdoor pools, summer season and weekends are potential high yield targets for drowning prevention efforts.

Addressing gaps in our understanding of the drowning patient: a protocol for the retrospective development of an Utstein style database and multicentre collaboration.

INTRODUCTION: This retrospective observational study aims to create a comprehensive database of the circumstances of drowning (including care provided and outcomes of care) to report against the Utstein style for drowning (USFD) for patients presenting to the emergency department (ED). Four areas will be examined: a feasibility study of the USFD; a comparison of classification and prognostication systems; examination of indications and efficacy of different ventilation strategies; and differences in the circumstances, severity, treatment and outcomes of drowning by sex and gender. METHODS AND ANALYSIS: This protocol outlines retrospective data collection for all patients presenting to EDs of the Sunshine Coast Hospital and Health Service in Queensland, Australia with the presenting problem or discharge diagnosis of drowning or immersion between 2015 and 2022. Patients computerised health records (emergency medical service record, pathology, radiology results, medical and nursing notes for ED, inpatient units and intensive care units) will be used to extract data for entry into an USFD database. Descriptive (eg, median, IQR) and inferential statistical analyses (eg, analysis of variance) will be used to answer the separate research questions. Development of an International Drowning Registry using the USFD dataset and the Research Electronic Data Capture (REDCap) web application is discussed. ETHICS AND DISSEMINATION: This study has been approved by Metro North Human Research and Ethics Committee (Project No: 49754) and James Cook University Human Research Ethics Committee (H8014). It has been endorsed by national drowning prevention organisations Royal Life Saving Society Australia (RLSSA) and Surf Life Saving Australia (SLSA). Study findings will provide data to better inform clinical management of drowning patients and provide an evidence base on sex and gender differences in drowning. Results will be disseminated through peer review publications, conference presentations and media releases. Results will also be disseminated through RLSSA and SLSA membership of the Australian and New Zealand Resuscitation Council and the Australian Water Safety Council.

Context of boat drowning in Ghana: a mixed qualitative research study.

BACKGROUND: Drowning is a significant public health challenge globally. In Africa and Ghana, drowning has remained a silent epidemic among poor communities. Limited evidence has challenged advances in drowning knowledge and prevention. While drowning deaths are often widely circulated in the newspapers, drowning data are not systematically organised to constitute a body of evidence sufficient for scientific exploration. Although drowning was frequent, they were poorly understood. We explore the context of drowning from multiple perspectives from the Volta-basin where the largest man-made lake in the world has become a hotspot for drowning. METHOD: This study adopts a sequential-mix-qualitative study comprising content analysis of newspaper reports on drowning, structured-observations and in-depth interviews with boaters and fisherfolk. We first explored, the content of newspapers over a 10-year period. This information provided the context of drowning. We followed up with extensive observation of activities on the lake by a team of five. Photovoice qualitative interviews were conducted with 22 boaters, fishers and community members. Thematic content analysis was applied to both the newspaper reports and the in-depth interviews. RESULTS: Drowning was attributed to both proximate and distal causes. Distal causes were the reasons for movement, while proximate causes were the immediate cause of the drowning. Travelling to farm, market, hospital, church, sell were important distal causes of drowning. Proximate determinants included strong winds, tree stumps, overcrowding, no-adherence to safety procedures, spiritual reasons and high tides. Four types of boat accidents were observed: boat-capsizing, boat-sinking, boat-splitting and boat-catching-fire. Ideas converged and diverged in comparing the newspaper content analysis to the photovoice interviews.

Atmospheric circulation and mortality by unintentional drowning in Spain: from 1999 to 2018.

AIMS: Drowning deaths are a leading cause of unintentional deaths worldwide. Few studies have analysed the role of meteorology in drowning, and with inconclusive results. The aim of this work is to analyse the temporal and geographical distribution of deaths by accidental drowning and submersion in Spain over 20 years, and to assess the relationship between accidental drowning and main atmospheric circulation patterns. METHODS: An ecological study was performed, in which drowning and submersion mortality data from 1999 to 2018, considering demographic variables, were analysed. To study the association with atmospheric circulation we used an ERA5 reanalysis product over the whole European continent and the Climatic Research Unit Time Series (CRU TS) data set. RESULTS: The annual average rate of deaths by accidental drownings was 11.86 deaths per million of habitants in Spain. The incidence in males was four times higher than in females, and when comparing age groups, the rate in the eldest group was the highest. Unintentional drowning deaths were not equally distributed around the country; the provinces with the highest registered standardized drowning death rates were touristic waterfront provinces either in Eastern Spain or in one of the archipelagos. There was a significant relationship between accidental drowning and meteorological variables during summer months, and drowning deaths were spatially correlated with sea-level pressure over the Mediterranean basin. CONCLUSION: Although the mortality rate registered a statistically significant decreasing tendency over the studied period, our results must be taken into consideration to improve the prevention strategies in the country since most of these deaths are avoidable.
