Introduction: The GOS-E Pediatric version allows measuring overall outcome in children and adolescents following ABI. Scores range from 1: upper good recovery, to 7: vegetative state.

Objectives: to validate the French translation of the GOS-E Peds in children with (ABI) of various severity and stages post-injury.

Methods: The GOS-E Peds was used in a PMR department devoted to children with ABI, in three groups of patients: (1) patients shortly hospitalised post-ABI: GOS-E Peds was rated upon admission, at 3 and 6 months post-injury; (2) patients several years post-injury, requiring services of a multi-disciplinary outreach team; (3) patients followed-up on simple medical clinics. The type and severity of ABI were collected.

Results: 398 patients were included [2/3 boys; mean age at injury 6 years (SD=4)].

In group 1 (n=124), mean (SD) GOS-E Peds scores were 5.9(.77) upon admission, 5.12(1.2) at 3-months (n=99) and 4.88(1.45) at 6-months (n=83); scores were significantly worse in case of hemiplegia (66%). GOS-E Peds improved over time (0-3 months p<0.0001; 3-6 months p=0.001). Although age at injury was not correlated with initial rating of GOS-E Peds (r=-.18), younger age at injury was correlated to worse GOS-E Peds scores at 3 and 6 months (r=-.3 and -.44; p<0.001).

In group 2, 101 patients were cross-sectionally assessed by the outreach team in April 2014 [mean age 14.8 (SD=4) years]. Mean GOS-E Peds was 3.95 (SD=1.4). Factors influencing GOS-E Peds were presence of cerebellar signs, younger age at injury (r=-.29; p=0.003) and lower intellectual ability (r=-.27; p=0.008).

In group 3, 173 patients consecutively seen in clinics were assessed [mean age 10.4 years (SD=4.5)]. Mean GOS-E Peds score was 3.3 (SD=1.5). Presence of hemiplegia and cerebellar signs were significantly related to GOS-E Peds scores.

Duration of coma, presence of diffuse brain injury and epilepsy negatively influenced GOS-E Peds scores in the three groups.

Conclusions: The GOS-E Peds has good sensitivity to change, and higher levels when children need a multi-disciplinary outreach team in the long term, than when they require simple clinic follow-up. Young age at injury, diffuse brain injury, epilepsy, motor impairments, and intellectual ability all significantly influence overall outcome.
