E-scooter: types of injuries examined

E-scooters have been approved for road traffic in Germany since June 2019. Since then, more and more rental vehicles from various providers can be found in many major cities. The devices are easily accessible, fast and often entice a risky driving style, so that accidents are more likely. The first findings on accident mechanisms and injury patterns after e-scooter accidents have now been published.

Scan the code with your smartphone, push it with your foot, accelerate and go: E-scooters, also known as e-scooters or e-scooters, are very popular in large German cities. The Charité - Universitätsmedizin Berlin has now analyzed the accident mechanisms and examined the types of injuries. The first results of the case series were published in the specialist magazine "Emergency + Rescue Medicine".

Treatments after e-scooter accidents

According to a message, more than 3,000 e-scooters have been in Berlin's city center since mid-June last year. There is currently no helmet requirement for electric scooters and their use is permitted from the age of 14. Because they can reach a speed of up to 20 kilometers per hour, they are only allowed on roads and bike paths.

But what are the greatest dangers of the trend vehicles? The team around Prof. Dr. Martin Möckel, medical director of emergency and acute medicine at the Charité Mitte campus and at the Virchow-Klinikum campus, examined all patients who had been in the central emergency department of the Charité at the Charité Mitte campus and after Virchow-Klinikum campus were treated.

The injured either introduced themselves or were brought in with the emergency services. The examination results and the therapeutic measures were documented as standard. In addition, all patients were given questionnaires asking demographic information, experience in road traffic, as well as driving license and driving behavior.

Different causes of accidents

The specialists examined a total of 24 patients between the ages of 12 and 62 in July. The experts found that over half were male. 14 patients were younger than 30 years, four of them were under 18. Ten injured said that they were resident in Berlin, the others were tourists.

Less than half of those examined had a driver's license, and around a third had previously used an e-scooter at least once. The survey found that the causes of the accident were often carelessness, violations of traffic rules and terms and conditions, but also limited roadworthiness.

Prof. Möckel said of the results: "Our studies show that driving e-scooters in city traffic is at least comparable to cycling in terms of the frequency and severity of the injuries."

Crack wounds, fractures and head injuries

According to the data, the survey makes it clear that typical vehicle injuries include, for example, lacerations on the upper ankle, fractures of the upper extremities and head injuries. Over 54 percent of the patients suffered head injuries. These were mostly minor bruises with abrasions.

Four of the 24 injured had mild traumatic brain injuries. The frequent soft tissue injuries on the lower extremities in the area of ​​the upper ankle were caused by the careless start of the e-scooter.

"With our first case series, we wanted to show what the typical injury patterns for e-scooters are, which emergency doctors, emergency physicians and surgeons will be confronted with in the future," says Prof. Möckel.

A prospective case-cohort study is currently being carried out at the Charité and at the Bundeswehr Hospital in Berlin for a more detailed analysis of injury patterns and their consequences.

Broken bones and concussions

A US study on the risk of injury to e-scooters and e-bikes also showed that broken bones and concussions were common.

The researchers had access to significantly more data collected by the U.S. government in emergency rooms across the country. They compared the patterns of injuries reported between 2000 and 2017 that were caused by e-bikes, e-scooters and normal bicycles.

During the study, there were approximately 130,000 injuries related to e-scooters compared to around 3,000 injuries on the e-bike. The study results were published in the journal "Injury Prevention". (ad)
