Evaluating the quality of online information about concussions.

Objectives: Compare and assess information available on the Internet about the definition, symptoms, treatment, and return to play recommendations after a concussion.
Methods: The top 10 websites generated by a Google search on the keyword "concussion" were evaluated by two independent researchers and three medical professionals for definition, signs, symptoms, home treatment, care-seeking advice, and return to play recommendations. The medical professionals also rated their willingness to recommend each website to patients.
Results: Each website contained a general list of signs, symptoms, and home treatment. One website advised the use of ibuprofen, four advised against ibuprofen, and five made no medication recommendations. Nine websites contained guidance on seeking physician care, and eight recommended athletes not return to play until cleared by a healthcare professional.
Conclusion: Nine of the websites contained information for each section evaluated; however, information was inconsistent. Healthcare providers should be aware of the variable quality of information available on the Internet and guide patients to more optimal resources.
