Prognostic Factors of Dysphagia and Recovery Following Pediatric Acquired Brain Injury

Objectives: Dysphagia is a major complication of acquired brain injury (ABI) in children; however, its trajectory and prognostic indicators remain insufficiently characterized. This study aimed to identify predictors of dysphagia and its recovery following pediatric ABI. Methods: This retrospective study included all children admitted with ABI to tertiary pediatric rehabilitation center between 2014 and 2017. Data were collected from electronic medical records. Results: One hundred children aged 2:00–17:11 years were included; 61% had dysphagia at admission. Participants with dysphagia received speech–language pathology (SLP) treatment, with a recovery rate of 78.68%. Treatment duration was significantly shorter among children who recovered (36 days) compared with those who did not (136 days; p < 0.001). Dysphagia at admission was associated with mechanical ventilation, duration of unconsciousness, duration of acute hospitalization, CNS tumor etiology, cranial nerve impairment (V, IX, X, XII), voice and speech impairments, and cognitive and behavioral impairments. Logistic regression showed that reduced consciousness, cranial nerve impairment, voice disorders, and CNS tumors explained 70.6% of dysphagia likelihood. Non-recovery was associated with unconsciousness, enteral feeding, hypoglossal injury, and dysphagia severity at admission. Level of consciousness at admission explained 33.7% of recovery likelihood. Conclusions: Dysphagia was highly prevalent among children with ABI. Recovery rates following SLP treatment were high and were associated with level of consciousness at admission to rehabilitation.
