OBJECTIVE: To determine if health outcomes and demographics differ according to
helmet status between persons with cycling-related traumatic brain injuries
METHODS: This is a retrospective study of 128 patients admitted to the Montreal
General Hospital following a TBI that occurred while cycling from 2007-2011.
Information was collected from the Quebec trauma registry and the coroner's
office in cases of death from cycling accidents. The independent variables
collected were socio-demographic, helmet status, clinical and neurological
patient information. The dependent variables evaluated were length of stay (LOS),
extended Glasgow outcome scale (GOS-E), injury severity scale (ISS), discharge
destination and death.
RESULTS: 25% of cyclists wore a helmet. The helmet group was older, more likely
to be university educated, married and retired. Unemployment, longer intensive
care unit (ICU) stay, severe intracranial bleeding and neurosurgical
interventions were more common in the no helmet group. There was no significant
association between the severity of the TBI, ISS scores, GOS-E or death and
helmet wearing. The median age of the subjects who died was higher than those who
CONCLUSION: Cyclists without helmets were younger, less educated, single and
unemployed. They had more severe TBIs on imaging, longer LOS in ICU and more
neurosurgical interventions. Elderly cyclists admitted to the hospital appear to
be at higher risk of dying in the event of a TBI.
