Abstract

The purpose of this study is to compare the predictive utility of total number of individual symptoms endorsed, total symptom severity, and average symptom severity on prolonged recovery among children/adolescents with a concussion. Patients (n = 115) completed the Post-Concussion Symptom Scale (PCSS) at their initial clinical visit (7.9 ± 6.6 days) days post-injury. PCSS outcomes were total symptom severity (i.e., total PCSS score), number of symptoms endorsed (i.e., number out of 22-items on the PCSS with a symptom score >0) and average symptom severity (i.e., mean of scores for each of the 22-items on the PCSS, not just endorsed symptoms). Logistic regression was performed with all symptom measures and recovery time >30 days as the binary outcome. Logistic regression indicated that average symptom severity (OR = 1.9; p = 0.01) and later time to first clinical visit (OR = 5.0; p < 0.001) were the only significant predictors of recovery time. Average symptom severity at initial clinic visit and earlier clinical visit may be a better predictor of recovery time than total number of symptoms endorsed or total symptom severity among children and adolescents.

摘要

本研究的目的是比较认可的个体症状总数、总症状严重程度和平均症状严重程度对脑震荡儿童/青少年长期恢复的预测效用。患者（n = 115) 在受伤后的首次临床就诊 (7.9 ± 6.6 天) 天完成脑震荡后症状量表 (PCSS)。PCSS 结果是总症状严重程度（即总 PCSS 评分）、认可的症状数量（即，症状评分 > 0 的 PCSS 上的 22 个项目中的数量）和平均症状严重程度（即，每个项目的平均评分） PCSS 上的 22 项，而不仅仅是认可的症状）。以所有症状测量和恢复时间> 30天作为二元结果进行逻辑回归。Logistic 回归表明平均症状严重程度 (OR = 1.9; p = 0.01) 和第一次临床就诊的较晚时间 (OR = 5.0; p < 0.001) 是恢复时间的唯一重要预测因子。与儿童和青少年认可的症状总数或总症状严重程度相比，初次就诊和早期临床就诊时的平均症状严重程度可能是恢复时间的更好预测指标。
