Concussions are a common occurrence among adults, and a recent study has shed light on the potential risks associated with concussions and subsequent traffic crashes. Researchers at ICES and Sunnybrook Research Institute conducted a study titled “Concussions and risk of a subsequent traffic crash: retrospective cohort analysis in Ontario, Canada,” which was published in BMJ Open.
The study found that adults diagnosed with a concussion may face a 50% higher risk of being involved in a traffic crash. This increased risk is particularly significant in the first four weeks after a concussion and is further exacerbated by repeated concussions. The study also revealed that pedestrians crossing the street are also at risk of being involved in a traffic crash following a concussion.
Dr. Donald Redelmeier, a scientist at ICES and Sunnybrook Research Institute, expressed concerns about the recovery time needed for concussions. Symptoms such as insomnia, dizziness, depression, brain fog, and slowed reaction times can linger for weeks, affecting driving skills and increasing the likelihood of a motor vehicle accident.
The study highlighted that out of 425,158 adults diagnosed with a concussion, one in 13 patients were injured in a subsequent traffic crash. This increased risk resulted in significant consequences, including ambulance calls, hospital stays, and substantial medical costs.
While the study had some limitations, such as a lack of data on concussion severity and other predisposing factors, the findings underscore the importance of traffic safety following a concussion and the need to prevent concussions in the first place. Patients are advised to address symptoms like insomnia, headaches, depression, and substance misuse, and to avoid high-speed trips during late-night hours in bad weather during the first month after a concussion. Clinicians should also educate patients about road traffic safety post-concussion.
In conclusion, the study emphasizes the need for increased awareness and precautions regarding traffic safety following a concussion. By taking necessary steps to address symptoms and avoid risky behaviors, individuals can reduce the likelihood of being involved in a serious traffic crash after experiencing a concussion. The research findings serve as a valuable resource for both healthcare providers and the general public in promoting road safety and concussion prevention.
