Injury Prevention最新文献

Background: Suicide remains a major public health problem, and firearms are used in approximately half of all such incidents. This study sought to predict the occurrence of suicide specifically by firearm, as opposed to any other means of suicide, in order to help inform possible life-saving interventions.

Methods: This study involved data from the Minnesota Violent Death Reporting System. Models evaluated whether data beyond basic demographics generated increased prediction accuracy. Models were built using random forests, logistic regression and data imputation. Models were evaluated for prediction accuracy using the area under the curve analysis and for proper calibration.

Results: Results showed that models constructed with social determinants and personal history data led to increased prediction accuracy in comparison to models constructed with basic demographic information only. The study identified an optimised 'top 20' variables model with a 73% chance of correctly discerning relative incident risk for a pair of individuals. Age, height/weight, employment industry/occupation, sex and education level were found to be most highly predictive of firearm suicide in the study's 'top 20' model.

Conclusions: The study demonstrated that the use of a firearm in a death by suicide, as opposed to any other means of suicide, can be reasonably well predicted when an individual's social determinants and personal history are considered. These predictive models could help inform many prevention strategies, such as safe storage practices, background checks for firearm purchases or red flag laws.

Background: Falls are a leading cause of morbidity and mortality among older adults in the USA. Current approaches to fall prevention often rely on referral by primary care providers or enrolment during inpatient admissions. Community emergency medical services (CEMS) present a unique opportunity to rapidly identify older adults at risk for falls and provide fall prevention interventions in the home. In this systematic review, we seek to assess the efficacy and qualitative factors determining success of these programs.

Methods: Studies reporting the outcomes of fall prevention interventions delivered by EMS were identified by searching the electronic databases PubMed, Embase, Web of Science Core Collection, CINAHL and the Cochrane Central Register of Controlled Trials through 11 July 2023.

Results: 35 studies including randomised and non-randomised experimental trials, systematic reviews and qualitative research primarily from Western Europe, the USA, Australia and Canada were included in our analysis. Current fall prevention efforts focus heavily on postfall referral of at-risk community members. CEMS fall prevention interventions reduced all-cause and fall-related emergency department encounters, subsequent falls and EMS calls for lift assist. These interventions also improved patient health-related quality of life, independence with activities of daily living, and secondary health outcomes.

Conclusions: CEMS programmes provide an opportunity for direct, proactive fall prevention on the individual level. Addressing barriers to implementation in the context of current emergency medical systems in the USA is the next step toward widespread implementation of these novel fall prevention interventions.

Objectives: There has been extensive debate in the USA as to how laws regulating the carrying of concealed firearms affect crime and public safety. This study examines whether US state laws making it easier for civilians to obtain permits to carry concealed handguns in public increase defensive gun uses against violent threats and attacks in public.

Methods: We used National Crime Victimization Survey data from 39 metropolitan statistical areas (MSAs) in the USA over a 19-year period (1986-2004) to examine whether laws making it easier for civilians to obtain concealed carry permits are linked to higher levels of defensive gun use against violence in public spaces of metropolitan areas. Bivariate χ² tests and multivariate logistic regression models (controlling for actor and situational characteristics) were used with 7196 public incidents to examine whether the likelihood of the victim using a gun against an attacker(s) varied based on the type of concealed carry law in the MSA at the time of the incident.

Results: The prevalence of self-defensive gun use in this sample was not clearly related to the passage of permissive gun carrying laws. Although defensive gun use was more common in MSAs with permissive gun carrying laws, this difference was not consistently related in magnitude or statistical significance to the passage of those laws or the length of time they had been in effect.

Conclusions: Permissive concealed carry permit laws do not produce evident increases in self-defensive gun uses against crime in public locations.

Objective: Drunk driving is a major cause of road traffic injuries and deaths in Latin America. We evaluated the impact of a drunk driving intervention in Leon, Mexico on road traffic safety.

Methods: The intervention included increased drunk driving penalties, enhanced sobriety checkpoints and a young adult-focused mass media campaign, beginning 19 December 2018. We created a synthetic control Leon from 12 Mexican municipalities from a pool of 87 based on similarity to Leon using key predictors from 2015 to 2019. We assessed the effect of the intervention on road traffic collisions overall and collisions with injuries, deaths and involving alcohol, using data from police, insurance claims and vital registration.

Results: As compared with the synthetic control, Leon experienced significant postintervention lower police-reported total collision rate (17%) and injury collisions (33%). Alcohol-involved collisions were 38% lower than the synthetic control. Fatal collisions reported by police were 28% lower while vital registration road traffic deaths were 12% lower, though these declines were not statistically significant. We found no impact on insurance collision claims. There was heterogeneity in these changes over the evaluation year, with stronger initial effects and weaker effects by the end of the year.

Conclusions: Drunk driving policies in Leon led to fewer traffic collisions and injuries during the first year of implementation, with a weakening of this effect over time, similar to interventions in high-income settings and other Latin American countries. Supporting the expansion of similar policies to other cities in the region could improve road safety.

Background: Violent knife assaults ('stabbings') are underappreciated as a source of morbidity and mortality. The two objectives of this study were to describe the epidemiology of stabbing injuries in the population of Ontario, Canada and to assess the associations between two measures of neighbourhood marginalisation-material deprivation and housing instability, and the risk of stabbing injury.

Methods: We conducted a population-based case-control study over 2004-18 using linked administrative data. Cases suffered a stabbing injury resulting in an emergency department visit, hospitalisation or death. Four age and sex-matched controls were matched to each case. Multivariate logistic regression was used to assess the associations between neighbourhood material deprivation as well as housing instability and the risk of injury. Mean annualised injury incidences were estimated using the number of cases identified divided by the total population of Ontario for that year.

Results: We identified 26 657 individuals with a stabbing injury, of which 724 (2.7%) were fatal. The mean annualised incidence was 13.4 per 100 000 (95% CI: 12.7 to 15.9). Victims were disproportionately young (median age 25 years; IQR: 20-37 years) males (84.1%), from large urban centres (77.5%), and in the lowest income quintile (39.3%). In multivariate models, neighbourhood material deprivation (OR 1.45, 95% CI: 1.43 to 1.47) and housing instability (OR 1.4, 95% CI: 1.22 to 1.26) were associated with risk of injury.

Conclusions: Stabbing injuries are a substantial public health problem that affects individuals of all ages and demographics but disproportionately affects younger men in urban settings. There is a weak association between residence in marginalised neighbourhoods and the risk of stabbing injury. Future studies should aim to better understand the nature of this association and consider opportunities for public health interventions to reduce the burden of violent knife injuries.

Background: Research shows violence against women likely increases during emergencies. COVID-19's emergence exacerbated intimate partner violence (IPV), suggesting that healthcare services (HCS) should have increased IPV screening efforts and referrals of victims to support services. However, little is known about the prevalence of IPV screening and information provision during COVID-19 lockdowns.

Methods: We examined prevalence of 'ever been screened' (ES) for IPV and 'receiving information about support services' (RI) in HCS during COVID-19 lockdowns and compared these among non-immigrant Jewish women, immigrant Jewish and other women, and Palestinian women citizens in Israel. We collected data during Israel's second and third COVID-19 lockdowns (October 2020-February 2021) using a structured, online, self-administrated Arabic-language and Hebrew-language questionnaire. Eligibility criteria included women ≥18 years old, citizens of Israel, in a current intimate relationship (permanent or occasional) who used social media or smartphones. In total, 519 women completed the survey: 73 Palestinian, 127 Jewish immigrants and others, and 319 non-immigrant Jewish.

Results: Overall, 37.2% of women reported any IPV, of whom just 26.9% reported ES, 39.4% reported RI and 13.5% reported both (ES&RI). Palestinian women reported higher IPV rates (49.3%) compared with non-immigrant Jewish (34.2%) and immigrant Jewish and other (37.8%) women; however, they reported lower ES (OR 0.64, 90% CI (0.34 to 1.86) and RI 0.29 (0.17 to 0.50).

Conclusions: In a survey during COVID-19 lockdowns, only about one-quarter of women who reported IPV were ES for IPV, or RI about support services, suggesting strengthened IPV screening is needed in HCS during emergencies, particularly targeting minority women, who report higher IPV but receive fewer services.

Objectives: High-performance snow sports (HPSS) athletes compete in a performance-driven context with a high risk of injury. While there is a lack of evidence on effective prevention measures in snow sports, this study explored the perspectives and perceptions of HPSS stakeholders on sports injury prevention.

Methods: We conducted an exploratory qualitative study based on the grounded theory principles through 11 semistructured interviews with athletes, coaches and healthcare providers from different national teams about sports injury prevention. The interviews were inductively analysed through constant comparative data analysis.

Results: Participants defined risk management as a central concept in which they approached injury prevention by assessing, managing and sometimes accepting risks. Many factors, such as athlete-related and external factors, are considered in this process, ultimately influencing their decision-making. Participants acknowledged the value of experience when managing and dealing with risks, a key aspect of their learning process and career development. Within this context, open and trustworthy communication and shared responsibilities among all stakeholders influenced and shaped injury prevention strategies and behaviours. Understanding and balancing out speed and risks was considered pivotal in their daily practice. Therefore, injury prevention awareness, ownership, communication, teamwork and shared responsibilities may contribute to the success of sports injury prevention in HPSS.

Conclusion: These findings substantiate the significance of such contextual factors in sports injury prevention. Considering the high-risk nature of HPSS, injury prevention suggests a shift towards risk management strategies, with a strong emphasis on contextual factors and their interactions. Young athletes might benefit from educational interventions centred on developing skills to assess and manage risks.

Introduction: Firearm injuries are the leading cause of death among young people in the USA and disproportionately impact communities of colour and those experiencing socioeconomic distress. Understanding the personal goals of violently injured patients is essential to identifying protective factors and developing interventions that promote them. However, limited research characterising these personal goals exists.

Objective: The objective of this study was to use qualitative thematic analysis to analyse and describe the personal goals of young people who enrolled in a region-wide hospital-based violence intervention programme after surviving a violent injury.

Methods: A qualitative coding framework was developed, evaluated, and implemented using data from Life Outside of Violence, the St. Louis Area Hospital-Based Violence Intervention Programme. Chart abstraction procedures were used to compile qualitative data on Life Outside of Violence participants' personal goals documented by clinical case managers during individual treatment planning sessions with participants (n=168). Descriptive analyses are reported and implications for practice are discussed.

Results: Key findings reveal that (1) violent injury survivors have unmet therapeutic and resource needs, indicating the importance of having service providers with both clinical and case management skills, (2) anger management is a common clinical goal, and (3) employment opportunities are a common resource need.

Conclusions: Findings from this study inform the implementation of the Life Outside of Violence programme and offer a roadmap to other hospital-based violence intervention programmes operating nation-wide. Our results provide insight into participants' needs, desires, and motivations, allowing unique opportunities for improved participant engagement and service delivery.

Background: Children in households experiencing poverty are disproportionately exposed to maltreatment. Income support policies have been associated with reductions in child abuse and neglect. The advance child tax credit (CTC) payments may reduce child maltreatment by improving the economic security of some families. No national studies have examined the association between advance CTC payments and child abuse and neglect. This study examines the association between the advance CTC payments and child abuse and neglect-related contacts to the Childhelp National Child Abuse Hotline.

Methods: A time series study of contacts to the Childhelp National Child Abuse Hotline between January 2019 and December 2022 was used to examine the association between the payments and hotline contacts. An interrupted time series (ITS) exploiting the variation in the advance CTC payments was estimated using fixed effects.

Results: The CTC advance payments were associated with an immediate 13.8% (95% CI -17.5% to -10.0%) decrease in contacts to the hotline in the ITS model. Following the expiration of the advance CTC payments, there was a significant and gradual 0.1% (95% CI +0.0% to +0.2%) daily increase in contacts. Sensitivity analyses found significant reductions in contacts following each payment, however, the reductions were associated with the last three of the six total payments.

Conclusion: These findings suggest the advance CTC payments may reduce child abuse and neglect-related hotline contacts and continue to build the evidence base for associations between income-support policies and reductions in child abuse and neglect.
