Trends in drowning mortality in Portugal from 1992 to 2019: comparing Global Burden of Disease and national data

IntroductionImprecise data systems hinder understanding of drowning burden, even in high-income countries like Portugal, that have a well-implemented death certificate system. Consequently, national studies on drowning mortality are scarce. We aimed to explore drowning mortality in Portugal using national data and to compare these to Global Burden of Disease (GBD) estimates.MethodsData were obtained from the National Institute of Statistics (INE) for 1992–2019, using International Classification of Diseases (ICD)-9 and ICD-10 codes, by sex, age group and cause (unintentional; water transport and intentional). GBD unintentional drowning data were obtained online. Age-standardised drowning rates were calculated and compared.ResultsINE data showed 6057 drowning deaths, 4327 classified as unintentional (75.2% male; 36.7% 35–64 years; 31.5% 65+years; 15.2% 0–19 years). Following 2001, an increase in accidental drowning mortality and corresponding decrease in undetermined intent was observed, coincident with Portugal’s ICD-10 implementation. GBD modelled estimates followed a downward trend at an overall rate of decrease of −0.41/decade (95% CI (−0.45 to –0.37); R2adj=0.94; p<0.05). Conversely, INE data showed an increase in the rate of drowning deaths over the last decade (0.35/decade; 95% CI (−0.18 to 0.89)). GBD estimates were significantly different from the INE dataset (alpha=0.05), either underestimating as much as 0.567*INE in 1996 or overestimating as much as 1.473*INE in 2011.ConclusionsWhile GBD mortality data estimates are valuable in the absence of routinely collected data, they smooth variations, concealing key advocacy opportunities. Investment in country-level drowning registries enables in-depth analysis of incident circumstances. Such data are essential to informing National Water Safety Plans.

Occupational injury among paramedics: a systematic review

IntroductionParamedics are frequently exposed to acute and/or chronic environmental, operational and patient-related factors that increase their risk of physical and psychological injury. However, there has been wide variation in reported paramedic injury rates. This systematic review aims to synthesise the evidence to examine the incidence and nature of occupational injury among paramedics.MethodsThis systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO 2020: CRD42020164556). A systematic search of four electronic databases was conducted for the years 2004–2019. Peer-reviewed studies examining the incidence and proportions of paramedic occupational injury within civilian emergency medical services (EMS) were included. Injury types, mechanisms, contributing factors and incidence of injury were synthesised narratively.ResultsTwelve studies met the inclusion criteria. The incidence of injury ranged from 29.7 to 345.6 injuries per 1000 workers per year. Sprains and strains were the most reported injury types, and the trunk and upper limbs were the main sites. Body motion was the most frequently reported mechanism of injury, accounting for 35%–55% of all injuries. Female paramedics had a proportionally higher rate of injury compared with male paramedics. Paramedics aged 25–34 years accounted for the majority of fatal (mean 34.0%) and non-fatal (mean 51.7%) injuries.ConclusionThis review highlights the increased risk of occupational injury among paramedics and provides further insight into their overall injury profile.

Prospective longitudinal study investigating predictors of childhood injuries from Growing Up in New Zealand cohort: study protocol

BackgroundInjury is one of the leading causes of mortality and morbidity worldwide and yet preventable and predictable. In New Zealand (NZ), unintentional injury is the leading cause of emergency department visits, hospitalisations and death among children, making it a significant public health concern.ObjectiveTo identify the factors that place young children in NZ at an increased risk of unintentional injury.MethodsThis study will investigate injuries among children from the prospective Growing Up in NZ birth cohort of 6853 children and their families. The primary outcome of interest is injury events where medical treatment was sought. The data sources include parental reports of child injury and Accident Compensation Corporation—NZ’s no-fault injury compensation system—injury claims. The linked datasets will be utilised to examine the distribution of life course exposures and outcome data using descriptive statistics. A temporal multilevel model will then be developed to examine relationships between neighbourhood, child and family characteristics and injury from birth to 5 years of age for all children for whom parental consent to link data were obtained.DiscussionThe findings of this research will help to identify how the multiplicity of influences between children, family and their broader societal context acting across time affect their risk of experiencing a preschool injury. This information will provide an evidence base to inform context-relevant strategies to reduce and prevent childhood injuries.

Predictors of health-related quality of life following injury in childhood and adolescence: a pooled analysis

BackgroundInjury is a leading contributor to the global disease burden in children and places children at risk for adverse and lasting impacts on their health-related quality of life (HRQoL) and development. This study aimed to identify key predictors of HRQoL following injury in childhood and adolescence.MethodsData from 2259 injury survivors (<18 years when injured) were pooled from four longitudinal cohort studies (Australia, Canada, UK, USA) from the paediatric Validating Injury Burden Estimates Study (VIBES-Junior). Outcomes were the Paediatric Quality of Life Inventory (PedsQL) total, physical, psychosocial functioning scores at 1, 3–4, 6, 12, 24 months postinjury.ResultsMean PedsQL total score increased with higher socioeconomic status and decreased with increasing age. It was lower for transport-related incidents, ≥1 comorbidities, intentional injuries, spinal cord injury, vertebral column fracture, moderate/severe traumatic brain injury and fracture of patella/tibia/fibula/ankle. Mean PedsQL physical score was lower for females, fracture of femur, fracture of pelvis and burns. Mean PedsQL psychosocial score was lower for asphyxiation/non-fatal submersion and muscle/tendon/dislocation injuries.ConclusionsPostinjury HRQoL was associated with survivors’ socioeconomic status, intent, mechanism of injury and comorbidity status. Patterns of physical and psychosocial functioning postinjury differed according to sex and nature of injury sustained. The findings improve understanding of the long-term individual and societal impacts of injury in the early part of life and guide the prioritisation of prevention efforts, inform health and social service planning to help reduce injury burden, and help guide future Global Burden of Disease estimates.

Access to advanced-level hospital care: differences in prehospital times calculated using incident locations compared with patients’ usual residence

Studies estimate that 84% of the USA and New Zealand’s (NZ) resident populations have timely access (within 60 min) to advanced-level hospital care. Our aim was to assess whether usual residence (ie, home address) is a suitable proxy for location of injury incidence. In this observational study, injury fatalities registered in NZ’s Mortality Collection during 2008–2012 were linked to Coronial files. Estimated access times via emergency medical services were calculated using locations of incident and home. Using incident locations, 73% (n=4445/6104) had timely access to care compared with 77% when using home location. Access calculations using patients’ home locations overestimated timely access, especially for those injured in industrial/construction areas (18%; 95% CI 6% to 29%) and from drowning (14%; 95% CI 7% to 22%). When considering timely access to definitive care, using the location of the injury as the origin provides important information for health system planning.

Non-fatal gunshot injuries during criminal acts in Mexico, 2013–2019

IntroductionAs the volume of firearms (legal and illegal) in Mexico grows, gun violence has become a major public health challenge. While studies have focused on gun-related homicides and robberies, there is a dearth of research addressing non-fatal gunshot injuries. At the same time, official government sources report limited information and undercount these injuries.ObjectiveThe objective of this article is threefold. First, to provide data of non-fatal gunshot injuries sustained during crimes in Mexico; second, to estimate their initial individual healthcare costs; finally, to compare those costs to those resulting from other forms of injuries. This article contributes to discussions on gun violence in Mexico and its impact on public health.MethodsWe analysed Mexico’s National Crime Victimization Survey from 2014 to 2020.FindingsWe estimated that there were approximately 150 415 non-fatal gunshot injuries during crimes perpetrated from 2013 to 2019. We found that most non-fatal criminal gunshot injuries occur during a robbery and that victims tend to be men and young people between 18 and 35 years of age. Most of these injuries occur in urban areas and public spaces. While non-fatal gun-related injuries are not as common during crimes as other non-fatal injuries, their initial individual healthcare expenses are significantly higher. Crimes involving gun-related injuries reported an average expense of 16 643 pesos and crimes involving other forms of injuries reported an average of 1281 pesos. This discrepancy highlights the health burden associated with gun violence.

Perceptions of firearm-related harm among US adults living in firearm-owning households: a nationally representative study

Decision-making on having firearms at home may be contingent on perceptions of the likelihood of their negative and positive outcomes. Using data from a nationally representative survey (n=4030) conducted during 30 July 2019 to 11 August 2019, we described how US adults living in firearm-owning households perceived the relative likelihood of firearm-related harm by injury intent (‘accidentally harm self or someone else with a gun’, ‘injure self on purpose with a gun’ and ‘injure someone else on purpose with a gun’) for groups at risk of compromised decision-making (children; adolescents and individuals with mental health issues, substance use disorders or cognitive impairment). We found that US adults living in firearm-owning households believe that unintentional firearm injuries are more likely than intentional self-inflicted or assault-related firearm injuries, despite evidence to the contrary. Prior evidence indicates that communicating risk in relative terms can motivate behaviour change; therefore, findings from this study might helpfully inform health communications around firearm safety.

Effects of demolishing abandoned buildings on firearm violence: a moderation analysis using aerial imagery and deep learning

PurposeDemolishing abandoned buildings has been found to reduce nearby firearm violence. However, these effects might vary within cities and across time scales. We aimed to identify potential moderators of the effects of demolitions on firearm violence using a novel approach that combined machine learning and aerial imagery.MethodsOutcomes were annual counts of fatal and non-fatal shootings in Rochester, New York, from 2000 to 2020. Treatment was demolitions conducted from 2009 to 2019. Units of analysis were 152×152 m grid squares. We used a difference-in-differences approach to test effects: (A) the year after each demolition and (B) as demolitions accumulated over time. As moderators, we used a built environment typology generated by extracting information from aerial imagery using convolutional neural networks, a deep learning approach, combined with k-means clustering. We stratified our main models by built environment cluster to test for moderation.ResultsOne demolition was associated with a 14% shootings reduction (incident rate ratio (IRR)=0.86, 95% CI 0.83 to 0.90, p<0.001) the following year. Demolitions were also associated with a long-term, 2% reduction in shootings per year for each cumulative demolition (IRR=0.98, 95% CI 0.95 to 1.00, p=0.02). In the stratified models, densely built areas with higher street connectivity displayed following-year effects, but not long-term effects. Areas with lower density and larger parcels displayed long-term effects but not following-year effects.ConclusionsThe built environment might influence the magnitude and duration of the effects of demolitions on firearm violence. Policymakers may consider complementary programmes to help sustain these effects in high-density areas.
