There is some evidence that mental ill-health (MIH) is associated with injury at work, but data are sparse.
To examine, within a cohort of workers with a first workers' compensation claim, whether those with a history of MIH had a higher than expected number of second claims.
All Workers' Compensation Board (WCB) records from January 1995 to December 2004 were linked to administrative health records, and a physician diagnosis of MIH in the 48 months prior to the first WCB claim extracted. The first and second (if any) claim for each worker were identified and time to second claim calculated. Survival time to second claim was estimated by Cox regression with history of MIH as a covariate.
Results were available for 389 903 WCB first claimants. Of these 53% of men and 38% of women had a second claim, with a mean time between claims of 768 days (men) and 785 days (women). Those with a history of MIH were somewhat more likely to make a second claim and, in the survival analysis, to make this claim sooner. Type of injury at first claim did not appear to modify this effect.
Workers with a recent history of MIH at the time of making a first WCB claim for a work injury are at greater risk of a second injury, leading to a new claim. Strategies to get workers back to work after the first injury/claim should include management of MIH to reduce the risk of further injury.
有一些证据表明，心理健康不良（MIH）与工作中的伤害有关，但数据很少。
在首次申请工人赔偿的工人队列中，检查是否有 MIH 病史的人第二次索赔的人数高于预期。
将 1995 年 1 月至 2004 年 12 月的所有工人赔偿委员会（WCB）记录与行政健康记录相关联，并提取出首次 WCB 索赔前 48 个月内的 MIH 病史的医生诊断。确定每个工人的第一次和第二次（如果有）索赔，并计算第二次索赔的时间。使用 Cox 回归，将 MIH 病史作为协变量，估计第二次索赔的生存时间。
共有 389903 名 WCB 首次索赔人，其中 53%的男性和 38%的女性提出了第二次索赔，两次索赔之间的平均时间为 768 天（男性）和 785 天（女性）。有 MIH 病史的人更有可能提出第二次索赔，并且在生存分析中更早提出这一索赔。第一次索赔的受伤类型似乎并未改变这种影响。
在因工作受伤首次向 WCB 提出索赔时，近期有 MIH 病史的工人再次受伤并导致新索赔的风险更高。为了让工人在第一次受伤/索赔后重返工作岗位，应包括对 MIH 的管理，以降低进一步受伤的风险。
