EXECUTIVE SUMMARY

The police currently collect statistics ( STATS19) on the number of cycle accidents and casualties on Scottish roads. This is confined to on-road accidents and excludes off road accidents or those accidents that the police do not attend.

The Scottish Executive Development Department commissioned research to explore the extent, the severity and the circumstances of all accidents in which pedal cyclists are injured.

Cycling casualties who reported to 5 Accident and Emergency departments across Lothian and Borders Health Board were asked to complete a questionnaire relating to their accident. In total completed forms were received from 806 casualties aged 5 or over who had been injured as a result of pedal cycle accident between 1 st September 2003 and 31 st August 2004. This data was compared with the STATS 19 data for the same area.

Main Findings:

  • More males than females are injured in cycling accidents by a ratio of 3:1 and this increases to 4:1 in adulthood.
  • Cycle accidents are more common in childhood. Fifty-four per cent of all accidents involved under 16 year olds with older children (aged 12-16 year old) being the most at risk.
  • Cycling accidents peak in the summer when there is greater scope for leisure cycling. The 6 months between April and September account for over 70% of all accidents and nearly 80% of all child casualties.
  • The accident rate increases at the weekend coinciding with greater opportunity for leisure cycling.
  • The peak time of day for accidents is late afternoon or early evening.
  • A third of all cycling casualties indicated that they had their accident on the road.
  • Thirteen per cent of cycling accidents occurred on the main road. Adults were much more likely than children to have a cycling accident on the main road.
  • There were large numbers of accidents on the pavement (29%). Forty three per cent of child accidents are sustained on the pavement.
  • The greatest proportion of accidents (41%) occurred off-road and are not therefore captured by STATS19.
  • A high proportion of off road accidents happened on cycle tracks, forest tracks or mountain bike trails (57%). Adults were more likely to have off-road accidents.
  • The majority of accidents (72%) from the hospital based sample involved no other vehicles. This contrasts markedly with the police recorded statistics where 96% of accidents involved other vehicles.
  • Adult cycling casualties were much more likely to be involved with a car than children. This is associated with a greater likelihood of cycling on main roads.
  • Overall, less than half the casualties (39%) had been wearing a helmet.
  • Adults were significantly more likely than children to be wearing a helmet (57% compared to 24%).
  • Helmet wearing declines as children get older but rises again after the age of 16.
  • Correlating with age, helmet wearing was lowest for those whose accident happened on the pavement (21%) and higher for those whose accident occurred on a main road (43%).
  • Helmet wearing was highest of all (55%) for off-road cyclists.
  • Those who were wearing a helmet were less likely to have an injury to their head or neck (7% compared to 14%) and this difference was more distinct for children.
  • Accidents were caused by a very wide range of circumstances and no single cause stood out within the hospital sample. Only 7% of hospital respondents attributed the cause to a motorised vehicle.
  • Thirty-four per cent of casualties were discharged on the same day without any need for follow up and only 4% of casualties were admitted. Twenty seven per cent required some follow up. There was no information on outcome for 35% of the sample. Children were more likely to be admitted than adults.
  • There was little difference in outcome depending on whether the accident took place on or off road.
  • Most common injuries were to upper limbs (38%) followed by lower limbs (20%). Injuries to the head or neck were sustained by 11% of total casualties.
  • There are a large number of casualties who report to the hospital with an injury serious enough for medical attention who do not appear in STATS19.
  • STATS19 describes a narrow range of causes with the involvement of a motorised vehicle being the predominant factor.
  • STATS19 is much less likely to record accidents sustained by children and more likely to record those sustained by adults.
  • It may be concluded that the STATS19 database underreports the full extent of on road cycling casualties in Scotland.
  • Consideration should be given to alternative means of collecting accident data relating to cycling accidents to improve coverage of on road reporting and extend coverage to include off road.
