Objective: To examine the impact of Florida's implementation of a mandatory PDMP on drug-related motor vehicle crashes occurring on public roads.
Methods: We employed a difference-in-differences approach to estimate the difference in prescription drug-related fatal crashes in Florida associated with its 2011 PDMP implementation relative to those in Georgia, which did not utilize PDMPs during the same period (2009-2013).
Results: In Florida, there was a significant decline in drug-related vehicle crashes during the 22 months post-PDMP. PDMP implementation was associated with approximately two (-2.21; 95%-CI: [-4.04,-0.37]; P<0.05) fewer prescribed opioid-related fatal crashes every month, indicating 25% reduction in the number of monthly crashes. We also conducted sensitivity analyses to investigate the impact of PDMP implementation on CNS depressants and stimulants as well as cocaine and marijuana-related fatal crashes but found no robust significant reductions.
Conclusions: The implementation of PDMPs in Florida provided important benefits for traffic safety, reducing the rates of prescription opioid-related vehicle crashes.
Policy implications: Mandatory PDMP implementation policies could decrease drug-related fatal vehicle crashes.
