Quality of Life Differences in Children and Adolescents With 0, 1 to 2, or 3+Persistent Postconcussion Symptoms

Context: Persistent postconcussion symptoms (PPCSs) are associated with lower health-related quality of life (HRQoL) in children and adolescents. Despite commonly cited criteria for PPCSs involving 3 or more complaints, many individuals experience just 1 or 2 symptoms that may still negatively affect HRQoL. Objective: To determine differences in HRQoL between children and adolescents with 0, 1 to 2, or 3thorn parent-reported persistent symptoms at 1 month postconcussion. Design: Prospective cohort study. Setting: Community practice clinics. Patients or Other Participants: Individuals aged 8 to 18 years presented for the initial visit within 3 days of a sport- or recreation-related concussion. One month later, parents or guardians reported persistent symptoms using the Rivermead Post Concussion Symptoms Questionnaire (RPQ). Individuals with complete symptom data were analyzed (n = 236/245, n = 97 females, age = 14.3 6 2.1 years). Participants were grouped by the number of discrete RPQ symptoms reported as worse than preinjury (0, 1-2, or 3thorn). Main Outcome Measure(s): Total summary and subscale scores on the Pediatric Quality of Life Inventory (PedsQL) 23-item HRQoL inventory and 18-item Multidimensional Fatigue Scale (MDFS). Results: Kruskal-Wallis rank sum tests highlighted differences in PedsQL HRQoL and MDFS total scores across symptom groups (PedsQL HRQoL: v2 2 = 85.53, P,.001; MDFS: v2 2 = 93.15, P,.001). Dunn post hoc analyses indicated all 3 groups were statistically significantly different from each other (P,.001). The median (interquartile range) values for the Peds QL Inventory HRQoL totals were 93.5 (84.2-98.8) for those with 0 symptoms; 84.8 (73.9-92.4) for those with 1 to 2 symptoms; and 70.7 (58.7-78.0) for those with 3thorn symptoms. The median (interquartile range) values for the MDFS totals were 92.4 (76.4-98.6) for those with 0 symptoms; 78.5 (65.6-88.9) for those with 1 to 2 symptoms; and 54.2 (46.2-65.3) for those with 3thorn symptoms. Similar group differences were observed for each PedsQL HRQoL and MDFS subscale score. Conclusions: Children and adolescents whose parents reported 1 to 2 PPCSs had lower HRQoL and more fatigue than those with 0 symptoms. Across all 3 groups, those with 3thorn persistent symptoms had the lowest HRQoL and most fatigue. These findings indicate the continued need for intervention in this age group to prevent and address PPCSs.
