Studies including children only | |||||
Bell [34] | Age <16 years old, mTBI of <48 hours’ duration, n = 366 | 366 | Scheduled phone contact in the first 3 months, standardized instruction handout, and a toll-free phone number CDC booklet (Facts about concussion and brain injury and where to get help), versus usual care | Fewer symptoms and less effect of symptoms on functioning at 6 months for the intervention group according to the post-traumatic symptom composite score (52.6 versus 46.0).

No reporting of confounding and poor outcome measure) |
Ponsford [37] | 6 to 15 years old, mTBI, GCS 13 to 15 | 130 | Contacted in 48 hours and received neuropsychological assessment in 5 to 7 days plus information booklet, versus no follow-up and no booklet | Less post-concussion symptoms in the intervention group at 3 months | Potential (not randomized, no concealment confounding) |

Information at discharge | |||||

Mittenberg [32] | Patients admitted for mTBI (adults), GCS 13 to 15 | 58 | A 1 hour meeting with a therapist plus a 10 page manual plus a 10 minute questionnaire, versus routine care | Intervention associated with shorter duration of symptoms (33 versus 51 days) and fewer symptoms at follow-up at 6 months | Unclear (sequence allocation, concealment, blinding and confounding) |
