Trajectory of Health-related Quality of Life Following Pediatric Concussion

Abstract

To assess changes in health-related quality of life (HRQOL) across a 12-month period following pediatric concussion and to explore whether psychological factors (ie, pre-injury mental health history, current symptoms of anxiety and depression, sleep disturbance, or grit) were associated with HRQOL. Prospective cohort study design using data collected from patients presenting to a speciality care concussion program, with each patient followed for 12 months after initial presentation. Comparison data were collected from non-concussed controls recruited from the community. A total of 49 concussed patients (median=15.4 years of age) completed the Pediatric Quality of Life Inventory (PedsQL), Patient-Reported Outcome Measure Information Systems (PROMIS) Anxiety and Depressive Symptoms short forms, Pediatric Sleep Disturbance forms, and a Short Grit Scale. Mixed effects models explored change in HRQOL across time. Total HRQOL at initial clinic presentation was significantly lower for concussed adolescents (Peds QL Total Score mean=72 [SD=16 ]) compared with non-concussed controls (mean=88 [SD=11], p <.001). HRQOL improved in the patients with concussion over a 6-month period after initial assessment with no significant changes thereafter. Pre-injury history of anxiety (coefficient= -11.388, CI=-18.49 - -4.28, p<0.001), current depressive symptoms (coefficient= -0.317, CI= -0.62 - -0.01, p<0.01), and sleep disturbance (coefficient=-0.336, CI=-0.71 - 0.04, p<0.05) all predicted lower HRQOL. HRQOL is significantly lower in the acute phase of pediatric concussion and steadily improves over the following 6 months. Psychological factors are linked to lower HRQOL and may serve as important indicators of risk for poor outcome.
