Our 'treated' state cohort (California, Delaware, Florida, Illinois, Massachusetts, Maryland, Oregon, Rhode Island, Vermont, and Washington) had ERPO effective dates after 2015 and before 2019, and experienced a statistically significant increase in petitions relative to the petition volume (zero) before ERPO implementation.</p><p><strong>Results: </strong>Significant reductions in state-month firearm violence rates were associated with ERPO policies in Rhode Island and Massachusetts (due largely to reductions in nonfatal firearm assault).

As the number of older drivers grows, it is increasingly important to understand clinical factors associated with an increased risk of MVC. A major barrier, however, is the lack of data. To address this, we linked two large-scale administrative databases, the New Jersey Safety and Health Outcomes (NJ-SHO) Data Warehouse, which contains information on all police-reported crashes in New Jersey from 2004 to 2019, and Medicare Fee-for-Service (FFS) insurance claims, which contains health care encounters and prescription drug dispensings among older adults in the United States over the same period.
