There are few studies that have investigated the long-term outcome of children who have been victims of shaken baby syndrome (SBS). However, the consequences appear to be significant and the data available from a social point of view are scarce. The main objective of this study was to define the medical and social outcome in 2016 of the infants who were victims of SBS and admitted to one of the Marseille university hospitals. The number of patients followed by a specialized team was evaluated along with their clinical state, living conditions, and whether a social support system such as the Child welfare system had been put into place.

The study was retrospective and descriptive. Patients under 1 year of age who were hospitalized between January 2005 and December 2013 and manifested clinical and paraclinical characteristics enabling the diagnosis of SBS were included in the study. The diagnosis was certain, probable, or possible according to the definitions given by the consensus of the 2011 shaken baby health authority conference (HAS).

Eighty babies qualified for the study, three of whom died in intensive care. Only ten of these patients (12.9%) had regular (annual) neuropediatric check-up during the whole study period. Thirty-seven patients (48%) had an annual neuropediatric check-up during the first 2 years only following the diagnosis. Only 12 of the children (15.6%) were still being followed after the age of 6. The children were followed up on average for 2.5 years (29.6 months). In 24 cases (31%), the last medical visit revealed an abnormal neurological examination including multiple disabilities due to spastic quadriplegia and severe intellectual deficit, which led to total dependency in half of these cases. Forty-four patients (57%) had a normal neurological examination. Concerning the babies’ social outcome, 50 patients (64.9%) had returned home, 12 (15.6%) benefited, from educational assistance at the patient's home (AEMO) following the ruling of a children's judge, and 19 (24.7%) were still placed in foster care (ASE). The average foster care placement lasted 34.7 months.

Long-term medical follow-up for children having sustained serious head injury as a result of abuse is inadequate. Sequelae such as multiple disabilities are less frequent than described in the literature. According to this study, a longer-term follow-up is necessary for children suffering from sequelae such as learning disabilities than what is actually possible in our center.
