Incomplete recovery in patients with minor head injury directly discharged home from the emergency department: a prospective cohort follow-up study.

Objectives: To determine the frequency of post-traumatic complaints and recovery rate of non-hospitalised patients with minor head injury (MHI) and their relationship with demographic and injury characteristics. We also evaluated the differences between patient groups in this least severe category of brain and head injury.

Design: Prospective cohort follow-up study.
