Their attraction as a last-mile transport resolution in city areas has seen an enormous uptake of e-scooters in cities all over the world, pushed by the simplicity of dock-free, smartphone-based schemes that make hopping on and off a breeze. But this comfort does come at a price to public well being, with analysis starting for instance a corresponding rise in hospital admissions. One study suggests they trigger extra accidents than bicycles, vehicles and even bikes.
“There are millions of riders now using these scooters, so it’s more important than ever to understand their impact on public health,” mentioned Dr. Joann Elmore, a professor of drugs on the University of California, Los Angeles (UCLA).
Elmore is a part of a analysis workforce investigating these impacts. In 2019, she was senior writer on a first-of-a-kind study detailing the sorts of accidents brought on by e-scooters, exhibiting that they generally trigger fractures and head accidents requiring remedy in an emergency division. And different research since have continued to focus on the risks of this fledgling mode of transportation.
One 2020 study revealed in JAMA Surgery discovered the incidence of annual e-scooter accidents within the US climbed from 4,582 in 2014, earlier than the emergence of ride-share scooter firms, to 14,651 in 2018, once they had grow to be much more commonplace. Nearly a 3rd of these have been head accidents – extra than double the speed endured by cyclists – with annual hospital admissions rising from 313 to 1,374 throughout the identical interval.
A 2021 paper titled “Electric Scooter-Related Injuries: A New Epidemic in Orthopedics,” discovered that of 397 sufferers presenting to an emergency room over a 12-month interval, solely 19 have been carrying helmets on the time of their accident. Twenty-five p.c of the circumstances required surgical procedure. Another systematic assessment revealed in 2021 estimated that each 100,000 journeys resulted in 20 to 25 emergency division visits.
It is smart that the extra individuals use e-scooters the extra accidents there might be, and generally that can lead to extreme accidents. But how do the dangers of e-scooters examine to different types of transport? A new study by Elmore and the UCLA workforce has explored this query by taking a look at 1,354 individuals injured in e-scooter accidents between 2014 and 2020 that required outpatient remedy in larger Los Angeles. That determine included pedestrians being hit by the scooters or tripping over them on sidewalks.
This knowledge was mixed with municipal knowledge on e-scooter use to calculate the incidence of accidents amongst customers, which the authors estimated to be 115 for each million journeys. Going by nationwide injury rates, the authors word this compares to eight accidents per million automobile journeys, 15 accidents per million bicycle journeys and 104 accidents per million motorbike journeys.
“The discovering that rates of accidents from e-scooters are much like rates for motorbike accidents is startling,” said Elmore. “The ease of public access to on-demand shareable scooters and safety regulations that are still in their infancy suggest that e-scooter operators, cities and health care providers will continue to see a significant number of injuries each year.”
The findings are consistent with another study published last year comparing the safety of e-scooters to motor vehicles, focusing on injured riders presenting to emergency departments in the state of Texas throughout 2018. It calculated an injury rate of 180 per million miles traveled, compared to the injury rate for motor vehicles in Texas at 0.9 per million miles traveled. “The noticed vehicle-miles-traveled-based e-scooter injury fee was roughly 175 to 200 instances greater than statewide or county particular injury rates for motorcar journey,” the authors concluded.
Of course not all accidents are created equal. While e-scooters can definitely trigger critical injury (the UCLA study concerned 21 sufferers despatched to crucial care and two dying from their accidents) they do not journey almost as shortly as bikes. The scientists have been unable to make any conclusions in regards to the comparative severity, however as a result of as a result of the study solely included knowledge from UCLA-associated well being clinics and did not contain sufferers handled at different services, they consider their figures relating to injury rates to be an underestimate.
“It is important to note that e-scooter injuries may be less severe and less fatal than motorcycle injuries, but we still think our e-scooter injury rate is an underestimate,” mentioned the study’s first writer, Dr. Kimon Ioannides.
The analysis was revealed within the journal PLOS One.
