BACKGROUND
Few studies investigate the influence of body part injured and industry on future workers' compensation claims.
METHODS
Using claims incurred from 1 January 2005 to 31 July 2015 (n = 77 494) from the largest workers' compensation insurer in Colorado, we assessed associations between worker characteristics, second claims involving any body part and the same body part. We utilized Cox proportional hazards models to approximate the probability of a second claim.
RESULTS
First claims represented 74.9% (n = 58 007) and second claims 25.2% (n = 19 487) of total claims. Sex, age, industry, and body part of the first claim were associated with the probability of second claims and the body part affected. The 5-year probabilities of second claims and same body part second claims were 27.0% (95% confidence interval [CI]: 26.6%-27.5%) and 6.2% (95% CI: 5.9%-6.5%) in males and 26.5% (95% CI: 26.0%-27.0%) and 6.7% (95% CI: 6.5%-7.0%) in females. Most second claims occurred within 3 years.
CONCLUSIONS
Most second claims occur within 3 years. Body part and industry-specific injury patterns suggest missed opportunities for prevention.
背景
很少有研究调查身体受伤部位和行业对未来工人赔偿要求的影响。
方法
利用科罗拉多州最大的工人赔偿保险公司从 2005 年 1 月 1 日至 2015 年 7 月 31 日期间（n=77494）发生的索赔，我们评估了工人特征、涉及任何身体部位的第二份索赔与同一身体部位的第二份索赔之间的关联。我们利用 Cox 比例风险模型来估计第二份索赔的概率。
结果
第一份索赔占总索赔的 74.9%（n=58007），第二份索赔占 25.2%（n=19487）。第一份索赔的性别、年龄、行业和身体部位与第二份索赔和受影响的身体部位的可能性相关。男性的第二份索赔和同一身体部位的第二份索赔的 5 年概率分别为 27.0%（95%可信区间：26.6%-27.5%）和 6.2%（95%可信区间：5.9%-6.5%），女性分别为 26.5%（95%可信区间：26.0%-27.0%）和 6.7%（95%可信区间：6.5%-7.0%）。大多数第二份索赔发生在 3 年内。
结论
大多数第二份索赔发生在 3 年内。身体部位和行业特定的伤害模式表明存在预防的机会。
