Association of Rideshare Use with Alcohol-Associated Motor V
Motor vehicle crashes (MVCs) are an important public health concern. By using rideshares to avoid impaired driving, young people may aid in decreasing motor vehicle trauma.

The objective of this JAMA Surgery study was to determine if there is an association between rideshare use and MVC traumas and convictions for impaired driving in Houston, Texas.

This multicenter cohort study was conducted with hospital data from the Red Duke Trauma Institute. Rideshare data from Uber and Google covered trips taken within Houston. Impaired driving convictions included all indictments made. All adults with MVC traumas evaluated at both centers in the study population (individuals >16 years with a mechanism of injury classified under “motor vehicle collision”) were included. Impaired driving incidents were included only if the final legal outcome was conviction. A total of 23?491 MVC traumas, 93?742 impaired driving convictions, and more than 24 million Uber rides were analyzed.

- Following the introduction of Uber in February 2014, MVC traumas decreased by 23.8% during peak trauma periods.

- The incident rate ratio of MVC traumas following Uber deployment was 0.33 per 1000 indexed rides.

- Furthermore, rideshare use was associated with a significant, geographically linked reduction in impaired driving convictions.

In this study, introducing rideshare services in the Houston metropolitan area was associated with significant reductions in MVC traumas and impaired driving convictions. Increased use of rideshares may be an effective means of reducing impaired driving and decreasing the rate of MVC traumas.
