STUDY DESIGN
Cross-sectional validation study.
OBJECTIVE
The aim was to validate the AO Spine Patient-Reported Outcome Spine Trauma (PROST) at a minimum of 12 months posttrauma and to evaluate patient characteristics, types of spine fractures, and treatment strategies as determinants of AO Spine PROST scores.
SUMMARY OF BACKGROUND DATA
The reliability and validity of the AO Spine PROST as a measure of health-related quality of life for more than 12 months after onset of spine trauma is unclear.
MATERIALS AND METHODS
Patients with a traumatic spine injury were recruited from a level-1 trauma center. They were asked to complete the AO Spine PROST, EuroQoL 5D-5L (EQ-5D-5L), and either Oswestry disability index (ODI) or neck disability index (NDI) for concurrent validity. Internal consistency was assessed by calculating the Cronbach α and item-total correlation coefficients. Test-retest reliability was evaluated using intraclass correlation coefficients. Spearman correlation tests were performed for the AO Spine PROST in correlation with the EQ-5D-5L, and either ODI or NDI. Determinants for AO Spine PROST score were analyzed using multivariate regression models.
RESULTS
A total of 175 patients participated in the cross-sectional arm and 49 in the test-retest arm of the study. Median duration of follow-up was 94.5 months. No floor or ceiling effects were seen. Internal consistency was excellent (α=0.98, item-total correlation coefficient: 0.73-0.91) as well as test-retest reliability (intraclass correlation coefficient=0.81). Satisfactory correlations were seen for the EQ-5D-5L (0.76; P <0.001), ODI (0.69; P <0.001), and NDI (0.68; P <0.001) with the AO Spine PROST. Multivariate linear regression models showed that having ≥1 comorbidities, duration of return to work within the range of 7 to 43 months and no return to work were significant independent determinants for a worse AO Spine PROST score.
CONCLUSIONS
Very good long-term reliability and validity results were found for the AO Spine PROST.
研究设计
横断面验证研究。
目的
旨在验证创伤后至少 12 个月的 AO 脊柱患者报告的结果脊柱创伤（PROST），并评估患者特征、脊柱骨折类型和治疗策略作为 AO 脊柱 PROST 评分的决定因素。
背景资料概要
在脊柱创伤发作后超过 12 个月，作为健康相关生活质量的衡量标准，AO 脊柱 PROST 的可靠性和有效性尚不清楚。
材料和方法
从一家 1 级创伤中心招募了外伤性脊柱损伤患者。要求他们完成 AO 脊柱 PROST、EuroQoL 5D-5L（EQ-5D-5L），以及 Oswestry 残疾指数（ODI）或颈部残疾指数（NDI）用于同时有效性评估。内部一致性通过计算 Cronbach α 和项目总分相关系数来评估。使用组内相关系数评估测试-重测可靠性。进行 Spearman 相关检验，以评估 AO 脊柱 PROST 与 EQ-5D-5L 之间的相关性，以及 ODI 或 NDI。使用多元回归模型分析 AO 脊柱 PROST 评分的决定因素。
结果
共有 175 名患者参加了横断面研究组，49 名患者参加了测试-重测研究组。中位随访时间为 94.5 个月。未发现地板或天花板效应。内部一致性非常好（α=0.98，项目总分相关系数：0.73-0.91），测试-重测可靠性也很好（组内相关系数=0.81）。与 AO 脊柱 PROST 相关，EQ-5D-5L（0.76；P<0.001）、ODI（0.69；P<0.001）和 NDI（0.68；P<0.001）的相关性均令人满意。多元线性回归模型表明，存在≥1 种合并症、工作恢复时间在 7 至 43 个月范围内和未恢复工作是 AO 脊柱 PROST 评分较差的显著独立决定因素。
结论
对于 AO 脊柱 PROST，发现了非常好的长期可靠性和有效性结果。
