Retrospective review of adverse incidents involving passengers seated in wheeled mobility devices while traveling in large accessible transit vehicles

Abstract

Objective Characterize wheeled mobility device (WhMD) adverse incidents on large accessible transit vehicles (LATVs) based on vehicle motion, WhMD activity during incident, incident scenario and injury. Design Retrospective records review. Subjects/patients WhMD passengers traveling on LATVs while remaining seated in their. Methods Adverse incidents characterized based on vehicle motion, WhMD activity during incident, and incident scenario. Injury characterized based on outcome, medical attention sought, vehicle activity, WhMD activity and incident scenario. Results 115 WhMD-related incident reports for years 2000–2005 were analyzed. Most incidents occurred when the LATV was stopped (73.9%), during ingress/egress (42.6%), and at the securement station (33.9%) when the LATV was moving. The combination of WhMD tipping and passenger falling (43.4%) occurred most frequently, and was 1.8 times more likely to occur during ingress/egress than at the securement station. One-third (33.6%) of all incidents resulted in injury, and injuries were equally distributed between ingress/egress (43.6%) and at the securement station (43.6%). Conclusions WhMD users have a greater chance of incurring injury during ingress/egress than during transit. Research is needed to objectively assess real world transportation experiences of WhMD passengers, and to assess the adequacy of existing federal legislation/guidelines for accessible ramps used in public transportation.
