Speed and spinal injuries

Abstract

Road traffic accidents (RTA) are a significant cause of spinal trauma. On the 31st of October 2002 a new penalty system for speed related driving offences was introduced in Ireland. Our intention was to assess the effects of the introduction of this system on the activity of the National Spinal Injuries Centre (NSIC) with a retrospective review of all admissions from November 1998 until October 2003. The number of new acute admissions to the spinal injury unit during the study period was 831. In the first 6 months of the new system the number of RTA related admissions fell significantly to 17 compared to an average of 33 in the preceding 4 years. However, this effect was not maintained in the second 6 months. The fall in spinal injuries following RTA in the first 6 months of the new system parallels the pattern of road death reduction in this period. This suggests that driving behaviour can be modified with direct benefits in reducing spinal injuries. However, this effect has not persisted in the second 6 months of the new system suggesting that to maintain this change the perception and familiarity of a penalty are important factors in its impact.
