Abstract
SALAZAR-HENAO, Edwin Alberto and CABRERA-ARANA, Gustavo Alonso. Years of life lost and spatial distribution of mortality from road incidents in Medellín, 2010-2020. Rev. Fac. Nac. Salud Pública [online]. 2023, vol.41, n.2, e03. Epub Nov 14, 2023. ISSN 0120-386X. https://doi.org/10.17533/udea.rfnsp.e347846.
Objective:
To estimate the potential years of life lost and the spatial distribution of mortality from road incidents by mode of transport in Medellín 2010-2020, as a baseline for the implementation of the Vision Zero strategy of the World Health Organization in the city's mobility.
Methodology:
This is a retrospective and descriptive cross-sectional study, with a secondary source. The calculation of the potential years of life lost was made using the life expectancy at birth in Colombia as the age limit, according to year and gender. The spatial analysis was carried out from the direction of the incident; Kernel density was represented by the standard-quantile classification method, and the zones of influence were created by the multiple ring buffer method, with distances of 500 and 1000 meters.
Results:
Between 2010 and 2020, Medellín registered 2,988 deaths due to road incidents. Those who died the most were pedestrians, with 1,423 (47.6%) deaths, followed by motorcyclists, with 1,295 (43.3%). Potential years of life lost were 98,787. The zones (comunas) with the highest concentration of pedestrian deaths were: Candelaria, Buenos Aires and Manrique; in motorcyclists, the highest concentration was evidenced in the river road system. By areas of influence, pedestrians killed within a radius of 1,000 meters from the river road system were 688 (49.8%), and motorcyclists, 636 (52.2%).
Conclusion:
Motorcyclists were the ones who died the youngest and the most years they stopped living. Polytrauma is a constant diagnosis of death, but injuries to the head, skull and thorax are more lethal in pedestrians and motorcyclists.
