Introduction: Motor vehicle crashes (MVC) are a leading cause of morbidity and mortality for teenagers. Graduated driver licensing (GDL) programs are a common intervention designed to reduce this burden on newly licensed teens. Objective: Compare rates of teenage driver involvement in injury producing MVCs by the Insurance Institute for Highway Saf...
Conference Paper
Background/Purpose: To describe injuries sustained in motorcycle crashes using the CDC Barell Injury Diagnosis Matrix. Methods: We studied Utah motor vehicle crash reports for motorcyclists from 1996-2009 probabilistically linked to emergency department (ED) and hospital billing records. We used the Barell matrix derived from ICD-9 CM diagnosis c...

Methods: The TACT intervention included concentrated media and enforcement focused on four targeted behaviors: following too...

Background Hospital charges are an important outcome in injury control research; however, these typically skewed distributions present analytic challenges. When analyzing charges, the median may be preferred to the mean due to its robustness to extreme values. The Crash Outcome Data Evaluation System (CODES) uses multiple imputed probabilisticall...
Conference Paper
The objective of this study was to demonstrate the use of the Crash Outcome Data Evaluation System (CODES) to more accurately describe contributing factors to work-related motor vehicle crashes. Methods: Police crash reports were probabilistically linked to emergency department and hospital inpatient data for the period of 1999-2005 in Utah. Freque...
Conference Paper
Introduction: Motorcycle crashes can result in significant morbidity and mortality. Helmets have been shown to reduce the risk of injuries and death. Universal helmet laws, requiring all motorcyclists to wear approved helmets, are one approach to increase helmet use. Objective: Compare the medical and hospital charge outcomes between motorcyclists...
Conference Paper
Objective: To better understand the consequences of crashes involving commercial vehicles (CVs) by comparing injury severity and citations issued to drivers in CV-passenger vehicle (PV), PV only, and CV only crashes. Methods: 2008 Utah police-reported crash records were used to produce counts and percents. Results: There were 2,867 CV-PV cras...
