Long-Term Reliability and Validity of the AO Spine PROST (Patient-Reported Outcome Spine Trauma)

Abstract

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.

Return to sports/activity level after 360° thoracolumbar fusion after burst fractures in young patients

“…No general guidelines exist but universal agreement that athletes should be neurologically intact, pain free and have full strength and range of motion before returning to play after spinal injury ( Huang et al, 2016 ). To survey outcome parameters the AO Spine PROST (Patient Reported Outcome Spine Trauma) is common with one question to recreation and leisure but not specific on sports activity level ( Buijs et al, 2022 ). The Tegner scale is originally and validated for the evaluation of sports level in knee injuries ( Tegner et al, 1985 ).…”

Validity of the short musculoskeletal function assessment questionnaire in patients with a spine fracture

“…Patient-reported outcome measures (PROMs) that accurately measure the impact of spinal injury are important tools to determine optimal treatment and cost-effectiveness [1]. One of the most commonly used condition-specific PROMs for spinal disorders is the Oswestry Disability Index (ODI) [2,3].…”
