The walking environment in Lima, Peru and pedestrian-motor vehicle collisions: an exploratory analysis.

ABSTRACT: Pedestrians comprise 78% of the road fatalities in Peru. The objective of this study was to explore the relationship between the walking environment and pedestrian-motor vehicle collisions.A matched case-control study was used to detect the odds of a pedestrian-motor vehicle collision at a pedestrian crossing location. Data were collected from 11 sampled police commissaries in Lima, Peru.In a multivariable model adjusting for vehicle and pedestrian flow, pedestrian collisions were less likely in the presence of a curb and sidewalk on both roadway sides (odds ratio [OR] = 0.19, 95% confidence interval [CI], 0.11-0.33) or a pedestrian barricade (OR = 0.11, 95% CI, 0.01-0.81). There was a greater risk of collisions for each street vendor present (OR = 2.82, 95% CI, 1.59-5.00) or whether any parked vehicles (OR = 3.67, 95% CI, 1.18-11.4) were present.Improving or addressing these potentially modifiable features of the walking environment could improve pedestrian safety in Lima and in similar urban settings in low- and middle-income countries.

Project description:Objective:Motor vehicle collisions generate considerable transmitted forces resulting in traumatic brain injury in children presenting to emergency departments (EDs). To date, no large study has examined post-concussive symptoms in children sustaining concussions in motor vehicle collisions. This study aimed to compare trends in acute post-concussive symptom burden in children with concussion following motor vehicle collisions as compared to other injury mechanisms. Methods:The study is a secondary analysis of the Predicting Persistent Post-concussive Problems in Pediatrics study, which prospectively recruited a multicenter cohort of 3029 children 5-17 years of age presenting to the ED with concussion from 2013-2015. Post-concussive symptom ratings were obtained at pre-specified time points for 12 weeks post-injury, using the validated Post-Concussion Symptom Inventory (PCSI). Symptom severity and recovery trajectories were measured using delta scores on the PCSI (mean post-injury symptom score minus perceived pre-injury score). A multivariable, longitudinal model evaluated the adjusted effect of mechanism of injury (motor vehicle collisions vs other mechanisms) on mean symptom scores, compared to perceived pre-injury reports, and the temporal change in mean scores over during recovery. Results:Of 3029 study participants, 56 (1.8%) sustained concussion from motor vehicle collisions. Children sustaining concussion in a motor vehicle collision had lower post-concussive symptom scores upon ED presentation, measured as differences from their perceived pre-injury reports, as compared to other injury mechanisms (-0.36 [95% confidence interval (CI) = -0.58, -0.15]). However, the motor vehicle collisions group showed the smallest decline in symptom burden over 1 month following injury (-0.54 [95% CI = -0.81, -0.27]). Conclusions:Children sustaining concussions in motor vehicle collisions may have lower initial symptom burdens but slower symptom recovery at 1 month compared to other mechanisms of injury and may represent a distinct population for prognostic counseling in the ED requiring further research.
