UNASSIGNED: The radiographs of fifty-seven patients were scored independently according to RUSHU methodology by three reviewers (blinded to patient outcome). Interobserver intraclass correlation (ICC) was calculated.
UNASSIGNED: Of the cohort, six (10.5%) progressed to non-union after six months. We observed an interobserver ICC co-efficient of 0.89 (95%CI0.84,0.93) in RUSHU score at six weeks. Median score was significantly higher in the union cohort (10v5 p < 0.001). Using the score of < 8 to predict non-union gave an area under the ROC curve of 0.87 (95%CI 0.83,0.90).
UNASSIGNED: In this retrospective single-centre study, we have demonstrated good inter-rater reliability. We would suggest that the RUSHU model be assessed in further external validation studies. RUSHU has the potential to reduce morbidity of delayed treatment of non-union.
■根据RUSHU方法,由三名评审员对57名患者的X光片进行了独立评分(对患者结局视而不见)。计算观察者间组内相关性(ICC)。
■在队列中,6人(10.5%)在6个月后进展为不工会。我们观察到6周时RUSHU评分的观察者间ICC系数为0.89(95CI0.84,0.93)。工会队列中的中位数得分明显更高(10v5p<0.001)。使用评分<8来预测不愈合给出了0.87的ROC曲线下面积(95CI0.83,0.90)。
■在这项回顾性单中心研究中,我们已经证明了良好的评分者间可靠性。我们建议在进一步的外部验证研究中评估RUSHU模型。RUSHU有可能降低不愈合延迟治疗的发病率。
