Differences in Concussion Diagnosis By Sex and Age Group in a General Population

ABSTRACT

Objectives: Female athletes have a higher risk of concussion than their male counterparts but there is a need to investigate these differences in a general population. We assessed reported concussions during a pre-COVID time period in a claims database to compare the prevalence across sexes and ages. Method(s) Using the MerativeTM MarketScan Commercial and Medicare Databases and Treatment Pathways tool, patients were included in the current study if they had continuous enrollment in the database from January 1, 2018 - December 31, 2019 and were between the ages of 14-65. The prevalence of concussions, identified using ICD-10-DX codes, was calculated for all cohorts (14-17, 18-23, >=24 years) and compared statistically between males and females. A secondary analysis, restricted to those with at least one year of continuous enrollment after the initial concussion, was conducted to determine if the proportion of patients who had a diagnosis code for a concussion at least 30 days after the first concussion differed across cohorts. Result(s) Approximately 9 million patients met the inclusion criteria for the study. A total of 66,098 patients had a claim for a concussion during the study period (56% female). The prevalence of concussions was 0.7% and 0.8% among males and females, respectively (p-value<.0001). Females were more likely to be diagnosed with a concussion than males in all age cohorts, with prevalence decreasing with age. Among patients with at least one concussion, 11.7% of males and 16.9% of females had a diagnosis code for a concussion at least 30 days after the initial code (p-value<.0001). Conclusion(s) This study supports previous research done in athletic populations and provides evidence that in a general population the prevalence of concussions is higher among females across all age groups. Further research is needed to investigate why the risk of concussion differs across sexes.Copyright © 2023
