2 . As reported in JAMA Surgery, the researchers discovered that e-scooter(电动摩托车) injury rates had increased dramatically in just four years, rising from 6 per 100,000 in the population to 19 per 100,000. Of the estimated 14,651 e-scooter-related injuries in 2018, 4,658, or 32%, involved the head. “While most people recover from head injuries, there is going to be a subset with long-term disability and life changes,” said Dr. Benjamin Breyer.

Dr. Benjamin Breyer of the University of California, Los Angeles, pointed to a 2019 analysis of the data from two hospitals in Southern California, which found just 4.8% of injured e-scooter riders were wearing helmets.

Dr. Joann Elmore, a professor of medicine at the University of California, Los Angeles, believed that most e-scooter users are probably unaware of the risks. To make the point, she described a photo taken by a colleague. “There were two riders on an e-scooter,” she said. “No one had shoes on. There were no helmets. And the woman in front had a baby in a baby carrier.”

The new report highlights the need for more research on new technologies, said Dr. Guohua Li, a professor of epidemiology(流行病学).

“Just as there is a global network of experts working on infectious diseases, there needs to be a similar program devoted to the surveillance(监视，监察) and prevention of injuries caused by merging technologies products and lifestyles, such as e-scooters, e-sports, etc.,” Li said in an email.

“The challenge for researchers and policymakers is to keep up with the ever-changing society and protect the public from unnecessary harm caused by new technologies and products without hindering innovation,” he added.
