Objectives To determine in Australian workers with an accepted workers’ compensation claim for low back pain (LBP) (1) the prevalence of diagnostic imaging of the spine and factors associated with its use, and (2) the association between spinal diagnostic imaging events and wage replacement duration. Methods Workers with accepted workers’ compensation claims for LBP longer than 2 weeks were grouped by whether workers’ compensation funded no, single, or multiple diagnostic spinal imaging in the 2 years since reported LBP onset. Ordinal logistic regression was used to define the demographic, occupational and social factors associated with each group. Time-to-event analysis was used to determine the association between spinal imaging and wage replacement duration. Results In the sample of 30,530 workers, 9267 (30.4%) received single spinal imaging and 6202 (20.3%) received multiple spinal imaging. Male workers and workers from the state of Victoria had significantly higher odds of multiple imaging. Socioeconomically advantaged workers and workers from remote Australia had significantly lower odds of multiple imaging. Magnetic Resonance Imaging was the most common imaging modality. Workers with single spinal imaging (median duration 17.0 weeks; HR 2.0, 95% CI 1.9, 2.1) and multiple spinal imaging (median duration 49.0 weeks; HR 4.0, 95% CI 3.9, 4.1) had significantly longer wage replacement duration than those with no imaging (median duration 6.1 weeks). Conclusions Over half of Australian workers with an accepted workers’ compensation claim for LBP longer than 2 weeks received diagnostic spinal imaging. Receipt of diagnostic imaging, particularly multiple imaging, was associated with longer wage replacement duration.

与澳大利亚工人的诊断成像相关的患病率、预测因素和工资替代持续时间与接受的腰痛索赔:一项回顾性队列研究

目的确定澳大利亚工人腰痛 (LBP) 的工伤赔偿要求已被接受 (1) 脊柱诊断成像的普遍性和与其使用相关的因素,以及 (2) 脊柱诊断成像事件与工资替代期限。方法接受超过 2 周的 LBP 工伤赔偿要求的工人,按照自报告 LBP 发病后 2 年内工伤赔偿是否资助无、单次或多次诊断性脊柱成像进行分组。序数逻辑回归用于定义与每组相关的人口统计、职业和社会因素。事件发生时间分析用于确定脊柱成像与工资替代持续时间之间的关联。结果在 30,530 名工人的样本中,9267 人(30.4%)接受了单脊柱成像,6202 人(20.3%)接受了多脊柱成像。来自维多利亚州的男性工人和工人进行多重成像的几率明显更高。具有社会经济优势的工人和来自澳大利亚偏远地区的工人进行多重成像的几率要低得多。磁共振成像是最常见的成像方式。单次脊柱成像(中位持续时间 17.0 周;HR 2.0, 95% CI 1.9, 2.1)和多个脊柱成像(中位持续时间 49.0 周;HR 4.0, 95% CI 3.9, 4.1)的工人的工资替代持续时间明显长于那些无成像(中位持续时间 6.1 周)。结论在接受超过 2 周的 LBP 工伤赔偿要求的澳大利亚工人中,超过一半接受了诊断性脊柱成像。接受诊断成像,特别是多次成像,与更长的工资替代持续时间相关。
