Exploring Age and Sex Patterns for Rehabilitation Referrals After a Concussion: A Retrospective Analysis

To explore patterns of postconcussion care at a level 1 trauma center.

Retrospective cohort study.

U.S. level 1 trauma center and local satellite units.

Patients of any age with a concussion diagnosis that reported to level 1 trauma center and local satellite units between 2016 and 2018 (N=2417).

Not applicable.

Age, sex, point of entry, rehabilitation referrals, and pre-existing comorbidity diagnosis.

Patient age (mean [SD]) significantly differed among points of entry, from youngest to oldest: 26.0 (14.0) years in sports medicine, 29.3 (23.0) years in the emergency department, 34.6 (23.6) years at primary care providers, and 46.0 (19.7) years at specialty care departments. Sex also significantly differed among points of entry; emergency departments reported more men (55.6%), whereas the other points of entry reported more women (59.3%-65.6%). Patients were more likely to receive a referral from sports medicine (odds ratio [OR]_unadjusted=75.05, P<.001), primary care providers (OR_unadjusted=7.98, P<.001), and specialty care departments (OR_unadjusted=7.62, P<.001) than from the emergency department. Women were more likely to receive a referral (OR_unadjusted=1.92, P<.0001), regardless of point of entry. Lastly, patients with a preexisting comorbidity were more likely (OR_adjusted=2.12, P<.001) to get a rehabilitation referral than patients without a comorbidity.

Point of entry, age, sex, and preexisting comorbidities are associated with postconcussion care rehabilitation referral patterns. Improving concussion education dissemination across all entry points of a level 1 trauma center may standardize the postconcussion rehabilitation referral patterns, potentially improving the time to recovery from a concussion.
