Description of intervention(s) / exposure
This prospective study is designed to examine the details of the crash circumstances, injuries and treatment of patients who come to the Emergency Department (ED) of Royal North Shore Hospital (RNSH), who have suffered either major or minor injuries as a result of an accident involving a bicycle.
Patients who present to the ED that fit the inclusion criteria and are not excluded as per the exclusion criteria will be approached by a member of the ED research team for consent to participate in the study. This include permission to access their medical records to examine the characteristics, patterns and outcomes of their bicycle injury and for permission to be contacted three-months following their discharge from the hospital to participate in a short 10-minute telephone interview/survey. Patient's who do not want to participant in the telephone interview but give permission for investigators to access their medical records related to this bicycle injury can indicate so on their consent form.
The data will be collected relating to the circumstances of the accident, injuries suffered and treatment received. This will be entered on the Bicycle Injury Study (BIS) Excel data file. This electronic file will be stored electronically on the RNSH system, governed by RNSH electronic security codes.
The telephone interview/survey will be conducted by a trained member of the ED department research team. The participant’s best contact number will be confirmed upon consent to the study. The survey will ask the participant questions to review their recovery from injuries and the short and long term impacts of their injuries.

Summary
Brief summary
Background: The benefits of cycling are increasingly recognised and promoted while safety is declining for cyclists in proportion to other road users and measures to protect cyclists are often ineffective. Falls (non-collision crashes) also cause severe injuries and crashes between bicycles in bicycle lanes can cause a high percentage of injuries. Unique data is therefore needed to inform the establishment of an safe system approach that takes into account and reconciles the needs of all road users, based on evidence based modifications, design values and passive safety measures in order to be a feasible method of giving cyclists equity in the transport system and balances the benefits of cycling with acceptable levels of safety.
Outcomes: 1) This study aims to identify and quantify differences in circumstances contributing to crash and injury amongst cyclists and identify the major contributing factors to injury severity. 2) Assessment of the 3 month recovery outcomes of injuries including the rate of recovery, impact of injuries on daily living activities and attitudes to more protective gear.
Participants: Injured pedal bikes riders over the age of 18 years presenting at the Emergency Department, Royal North Shore Hospital
Methods: Data will be collected from consenting patient records relating to the circumstances of the accident, injuries and treatment.
Patients who consent to participate in the follow up interview survey will be contacted three-months following their discharge from the hospital. The survey is in the form of a short 10-minute telephone semi-structured interview to review their recovery from injuries and the long term impact of their injuries.
