OHA release - What you should know:  E-scooters, e-bicycles and other micromobility options are expanding across Oregon.  Injuries involving e-bikes and e-scooters share common risk factors. E-scooter injuries are relatively new in health care reporting.  OHA monitors injury trends and works with partners to promote safe riding.  PORTLAND, Ore.—Oregon Health Authority (OHA) is urging riders to take safety precautions when using e-scooters and e-bicycles, as new data show a sharp increase in serious injuries associated with these “micromobility” or motorized devices.  An analysis by OHA’s Injury and Violence Prevention Program (IVPP), using Oregon hospital and emergency department discharge data, shows that e-scooter-related injuries more than doubled between 2021 and 2025, as use of these devices expanded statewide.  Between 2021 and Sept. 30, 2025, Oregon hospitals and emergency departments reported the following e-scooter injury visits, using recently developed, e-scooter-specific codes.  2021: 211 injuries; 2022: 269 injuries; 2023: 326 injuries; 2024: 418 injuries; 2025 (Jan-Sept 2025): 509 injuries.  “These injuries are not minor scrapes,” said Dagan Wright, Ph.D., senior injury epidemiologist and informaticist with OHA’s Public Health Division. “They often involve head injuries, broken bones and other serious trauma that requires emergency or inpatient care.”  Someone who knows the risk all too well is Portland e-scooter commuter Daniel Pflieger. He was riding a scooter home from work and slid on ice. The accident resulted in several bruised ribs. Luckily, Pflieger was wearing his helmet.  “I was biking home. It was late at night. It was just after one of the ice storms," said Pflieger. “But most of the ice had melted and I was going uphill. And it was not a well-lit street. I would say one, wear a helmet. Two, pay attention to your surroundings. A lot of drivers are not paying attention. I wear a second light.”  He added, “Really pay attention and ride at a comfortable speed. These things typically top out at 17 miles an hour, and it doesn't sound very fast, but when you're exposed to it, it can feel pretty fast.”  Watch e-scooter commuter Daniel Pflieger offer more of his micromobility safety tips.  E-scooter injury diagnosis codes are relatively new in health care reporting, making trend data from 2021 onward the most reliable period for understanding how injuries are changing over time, Wright explained. While the overall numbers remain smaller than for other transportation-related injuries, the rapid increase over a short period of time is a clear safety signal.
