This is the first large-scale study of US workers that describes the demographic and cost differences between recurrent and nonrecurrent low back pain (LBP) disability claimants, using data from a large workers' compensation insurer. Persons with at least one LBP claim in 1990 and one or more additional claims in 1990 to 1996 were defined as recurrent. Persons with at least one LBP claim in 1990 but no subsequent claims were defined as nonrecurrent. Fourteen percent of claimants were recurrent. The percentage of recurrent claimants who were male (77.2%) was higher than the percentage that were female (22.8%). This difference was more pronounced in the younger age groups. The median total cost for recurrent LBP claims in 1990 was 4% greater than for nonrecurrent 1990 LBP claims, whereas the mean cost was 48% less. Most studies of LBP recurrence among US workers have followed single-corporation employees. Our rate of recurrence was lower than these previously reported rates. However, analysis of independent workers' compensation insurance company data may provide a more accurate assessment of LBP claim recurrence among US workers.
这是对美国工人进行的首次大规模研究，利用一家大型工人赔偿保险公司的数据，描述了复发性和非复发性腰痛（LBP）残疾索赔者之间的人口统计学差异和成本差异。在1990年至少有一次LBP索赔且在1990年至1996年有一次或多次额外索赔的人被定义为复发性患者。在1990年至少有一次LBP索赔但随后没有索赔的人被定义为非复发性患者。14%的索赔者是复发性的。复发性索赔者中男性的比例（77.2%）高于女性（22.8%）。这种差异在较年轻的年龄组中更为明显。1990年复发性LBP索赔的总费用中位数比1990年非复发性LBP索赔高4%，而平均费用则低48%。美国工人中关于LBP复发的大多数研究都跟踪了单一公司的员工。我们的复发率低于之前报道的这些比率。然而，对独立的工人赔偿保险公司数据的分析可能会对美国工人中LBP索赔复发情况提供更准确的评估。
