BICYCLE COMMUTER INJURY: A ONE-YEAR PROSPECTIVE OBSERVATIONAL STUDY IN
PORTLAND, OREGON (IRB 3590)

This one-year prospective web-based study aims to quantify both the
incidence of traumatic injury associated with bike commuting in Portland,
Oregon and the impact of an injury on the individual's subsequent health and
employment. This study will also collect data regarding the "near misses"
which bike commuters experience as they ride to and from work. Although
bicycle commuting has been common in Portland for decades, the injury risks
associated with bicycling to work are virtually unknown.
There have been no studies of this size or scope published in the medical
literature. Up to 1,000 self-defined bike commuters will be recruited
throughout September 2007. Once enrolled, subjects will be requested to
fill out an initial online survey that will take no more than 15 minutes to
complete. At the end of each month, from October 2007 through September
2008, subjects will be asked (via email) to fill out a brief online survey
regarding their bike commuting habits for the past month. The survey will
usually take no longer than five minutes to complete., but may take up to 15
minutes to complete if the subject experienced an injury or a near miss
during the month.
As compensation for time spent, participants will receive an enrollment
package containing items provided by Ben and Jerry's, City of Portland and
Flexcar. Upon completion of each monthly survey, participants' names will be
included in a drawing for a variety of bicycle related items, including gift
certificates from the Bike Gallery.
