Estimating the Costs of Traumatic Injuries to Unbelted Occupants in Motor Vehicle Crashes

This project aims to estimate the costs of traumatic injuries suffered by adult occupants in motor vehicle crashes in Iowa from 2012 to 2016. The analysis will compare costs for occupants who are belted and not belted and also examine the financial burden of the injuries by payer (e.g., private insurance, Medicare, Medicaid, self-insured, uninsured). The analysis will also consider the effects of different crash, vehicle, and occupant characteristics, for example, seating position (i.e., driver vs. passenger, front seat vs. rear seat), number of vehicles, vehicle type, manner of crash or collision, number of occupants in the vehicles, location, or alcohol/drug involvement, on costs of injuries for unbelted occupants. The project team will conduct two phases of analysis. The first consists of tabulating the data and calculating descriptive statistics. At a minimum, the team will tabulate the number, types, and costs of injuries by: belt use status, seating position (driver, front passenger, rear passenger), insurance/payer, and two-way combinations of those variables. Additional tabulations can be defined based on Transport Accident Commission (TAC) input. During the second phase, the project team will conduct statistical analyses to quantify the effect of belt use, alone and in combination with other conditions like seating position and crash characteristics, on cost of injury. For this phase the project team would again welcome input from the TAC as to what analyses they would find most informative.
