RESUMEN
OBJECTIVE: To examine the degree to which neighborhood socioeconomic deprivation influences the risk of youth assault injury. STUDY DESIGN: Population-based retrospective study of youth aged 10-24 years seeking emergency medical care between 2012 and 2019 at 14 hospitals in Vancouver, Canada. Neighborhood material and social deprivation were examined as independent predictors of assault injury, accounting for spatial autocorrelation and controlling for neighborhood drinking establishment density. RESULTS: Our data included 4166 assault injuries among 3817 youth. Male sex, substance use, and mental health disorders were common among victims of assault. Relative to the least deprived quintile of neighborhoods, assault injury risk was 2-fold higher in the most materially deprived quintile of neighborhoods (incidence rate ratio per quintile increase, 1.17; 95% CI 1.06-1.30; P < .05), and risk in the most socially deprived quintile was more than 3-fold greater than in the least deprived quintile (incidence rate ratio per quintile increase, 1.35; 95% CI 1.21-1.50; P < .001). Assault risk was 147-fold greater between 2 and 3 AM on Saturday relative to the safest hours of the week. CONCLUSIONS: Neighborhood socioeconomic deprivation substantially increases the risk of youth assault injury. Youth violence prevention efforts should target socioeconomically deprived neighborhoods.

Injury is a leading cause of the global disease burden, accounting for 10 percent of all deaths worldwide. Despite 90 percent of these deaths occurring in low and middle-income countries (LMICs), the majority of trauma research and infrastructure development has taken place in high-income settings. Furthermore, although accessible services are of central importance to a mature trauma system, there remains a paucity of literature describing the spatial accessibility of emergency services in LMICs. Using data from the Service Provision Assessment component of the Demographic and Health Surveys of Namibia and Haiti we defined the capabilities of healthcare facilities in each country in terms of their preparedness to provide emergency services. A Geographic Information System-based network analysis method was used to define 5- 10- and 50-kilometer catchment areas for all facilities capable of providing 24-hour care, higher-level resuscitative services or tertiary care. The proportion of a country's population with access to each level of service was obtained by amalgamating the catchment areas with a population layer. A significant proportion of the population of both countries had poor spatial access to lower level services with 25% of the population of Haiti and 51% of the population of Namibia living further than 50 kilometers from a facility capable of providing 24-hour care. Spatial access to tertiary care was considerably lower with 51% of Haitians and 72% of Namibians having no access to these higher-level services within 50 kilometers. These results demonstrate a significant disparity in potential spatial access to emergency services in two LMICs compared to analogous estimates from high-income settings, and suggest that strengthening the capabilities of existing facilities may improve the equity of emergency services in these countries. Routine collection of georeferenced patient and facility data in LMICs will be important to understanding how spatial access to services influences outcomes.
