CHAPTER ONE: INTRODUCTION

1.1 BACKGROUND

The police currently collect statistics ( STATS19) on the number of road accidents involving cyclists on Scottish roads. This, by its nature, is confined to those accidents which occur on roads and to which the police are asked to attend. It does not provide any data on off-road accidents or on those accidents that the police do not attend. As a result there is little data on the full extent of cycle accidents, their severity or their cause.

1.2 AIMS AND OBJECTIVES

This study aimed to:

  • Compare hospital accident and emergency statistics on cycle casualties with STATS19 data to measure the extent of any gap.
  • Establish how many cycle accidents occur off road compared to on road.
  • Identify any patterns emerging on the type of accident, the location and the nature of the injury occurring.

1.3 METHODOLOGY

Five hospitals within the Lothian and Borders area which offer an Accident and Emergency (A&E) service agreed to take part in this study. They were:

  • Royal Hospital for Sick Children
  • Edinburgh Royal Infirmary
  • Western General
  • St John's Hospital
  • Borders General Hospital

Data was collected over the period of September 2003 to August 2004.

A proforma was designed to collect data relating to the casualty and the cycle accident. This was designed after consultation with the consultants or senior nursing officers at each of the five participating hospital departments and the Advisory Group established at the Scottish Executive.

It was essential that the form was kept as simple as possible and was easy to complete so that it could be fitted into the busy schedule that exists within all A&E departments. A copy of the proforma is appended to this report. ( Appendix 1)

The form was in two parts. The top half of the form was designed to be completed by the patients themselves and asked for simple details relating to:

  • The patient
  • The timing of the accident
  • The involvement of other vehicles
  • The presence of any safety aids
  • The location of the accident
  • Any other circumstances relating to the accident.

The bottom section of the form was designed to be completed by clinical staff and comprised of two main questions relating to:

  • The outcome - discharged with or without follow up, or admitted
  • Extent of injury and which part of the body was injured.

It was important that the staff at the A&E departments co-operated fully with this study if it was to be successful. Every effort was undertaken to maintain that vital co-operation including personal visits to ensure that staff had a say in how the study was designed, briefings for staff at appropriate points in the year and personal collection of completed data sheets throughout the year. In addition a small goodwill incentive was provided to participating hospitals.

All staff were briefed at the start of the study explaining it's purpose and the data collection requirements. An information sheet was also prepared for patients which clinical staff were asked to distribute with the questionnaire. A copy of the information sheet is also appended to this report. ( Appendix 2)

In some hospitals the researcher was given access to clinical staff to brief them herself and in others she briefed only senior staff who then took on this role with other staff. At no location was it possible to brief all staff due to the shift system in operation but efforts were made to brief as many staff as possible. There was therefore a need to cascade information and there was a system in place in hospitals to undertake this.

Staff at the hospitals were asked to complete a form for ALL casualties who were riding a bicycle at the time of their accident and who presented at a hospital Accident and Emergency department.

Regular visits were made throughout the year to collect forms and to ensure that there were no difficulties. Junior doctors at the Royal Hospital for Sick Children and Edinburgh Royal Infirmary who joined the departments in February 2004 were provided with another briefing similar to that given at the start of the study.

There was no practical means of auditing how well the data was being collected by the A&E departments and whether there was a form collected for every cycling casualty, as requested. There were some problems in getting the clinical staff to complete the outcome section of the form and in 35% of the sample this was left blank.

1.4 STATS19

Lothian and Borders Police provided their STATS19 data on pedal cycle casualities resulting from road accidents. This was compared to the data collected in this hospital based study.

1.5 STRUCTURE OF THIS REPORT

Across all five hospitals completed forms were received from 806 casualties aged 5 or over who had been injured as a result of a pedal cycle accident between 1 st September 2003 and 31 st August 2004.

Chapter 2 of this report provides data on who was involved in those cycle accidents. Chapter 3 explores when cycle accidents happened. Chapter 4 examines the extent to which other vehicles were involved in the accident and Chapter 5 looks at the location of cycle accidents, in particular examining those that were on-road compared to those off-road. Chapter 6 examines the incidence of safety aids at the time of the accident. Chapter 7 looks at the factors contributing to the accident whilst Chapter 8 goes on to examine the extent of the injury caused by the accident, looking at the outcome for the casualty and the type of injury sustained. Chapter 9, examines the STATS19 data, looking at the differences between this dataset and that collected via the hospitals. Chapter 10 concludes the report and raises some methodological issues in relation to the future collection of data on cycling accidents.
