Adult moped-related injuries treated in U.S. emergency departments.

Objective: Few studies have investigated U.S. emergency department (ED) moped-related injuries. Our objective was to determine the characteristics of moped crashes among adult riders and to identify associations between key variables.Methods: Data were obtained from the National Electronic Injury Surveillance System (NEISS) for 2002-2014. Descriptive and comparative analyses of the identified cases were performed.Results: Based on a probability sample of 2,453 cases, an estimated 108,229 U.S. adult moped-related ED visits occurred during the study period. Injuries increased 2.7-fold over time. Summer months and weekdays were the most common crash times. Three-fourths of injured riders were male, two-thirds were ages 23-59 years, and 77% were Caucasian. Among cases documented, one-half were helmeted, and almost two-thirds of crashes occurred at ≤20 mph. The predominant mechanism was a non-collision crash (60%). Skin-related and musculoskeletal diagnoses were most common. Almost one-fifth of patients were admitted or transferred. Regression analyses showed that males were less likely than females to be in crashes with multiple riders, and more likely to have used alcohol/drugs and to be in a crash with another motor vehicle (MVC). Older riders (≥40 years) were more likely than those younger to have used alcohol/drugs and to suffer torso injuries, and less likely to be in an MVC. As compared to other crash mechanisms, MVCs were more likely to involve injuries to the head/neck/face and torso. The likelihood of being admitted/transferred was higher for males, with increasing age, and for collision-related crashes. The higher likelihood of being admitted/transferred was also characterized by alcohol/drug use, by lower limb and torso injuries, and almost 8 times more likely for riders with serious head injuries.Conclusions: Moped injuries increased in all adult age groups during the study period. However, there were significant differences in contributing factors, crash mechanism, and outcomes by sex, race, and age. These findings suggest the need for targeted injury prevention interventions.

Pediatric moped-related injuries in the United States from 2002 to 2014: Age-related comparisons of mechanisms and outcomes.

Mopeds are a popular means of transportation, especially in urban areas. However, few studies have investigated moped-related injuries in the United States. This study's goal was to compare the crash mechanisms and injuries suffered in moped-related crashes involving youth versus adults, as well as between younger and older children. INTRODUCTION: Mopeds are a popular means of transportation, especially in urban areas. However, few studies have investigated moped-related injuries in the United States. This study's goal was to compare the crash mechanisms and injuries suffered in moped-related crashes involving youth versus adults, as well as between younger and older children. METHODS: Descriptive and comparative analyses were performed using National Electronic Injury Surveillance System (NEISS) data and additional variables coded from injury narratives. Multivariate regression analyses were used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for categorical outcomes, controlling for significant covariates. RESULTS: From 2003 to 2014, there were 779 youth (17 years or younger) and 2,453 adult moped-related emergency department visits in the database. The number of youth injured remained relatively constant over time, while the number of adult victims doubled. Relative to 14- to 17-year olds, victims younger than 14 years were more commonly female (p = 0.037) and non-Caucasian (p = 0.008). Victims 14 to 17 years of age had a higher proportion of brain injuries (p = 0.012) and were more commonly in motor vehicle collisions (p = 0.02), as compared to younger victims. Relative to adults, youth crashes occurred more commonly in the summer (p < 0.0001), and off the street/road (p < 0.0001). Logistic regression analysis showed crashes on streets/roads were two and a half times more likely to involve victims who were 14 to 17 years of age as compared to those younger (aOR, 2.55; CI, 1.64-3.97). Additionally, male youths were twice as likely as females to have a motor vehicle collision (aOR, 1.97; CI, 1.19-3.24), and pediatric crashes were approximately twice as likely to result in extremity injuries as compared to adult crashes (aOR, 1.95; CI, 1.19-3.20). CONCLUSION: Differences in crash mechanism and injuries sustained between two youth age groups and between youths and adults indicate the importance of targeted injury prevention efforts. This would include improved operator training and standardized, evidence-based, well-enforced safety legislation. LEVEL OF EVIDENCE: Epidemiologic study, level III.
