This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices.
Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence.
In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant.
This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices.
本文旨在评估三个不同层级工作场所结构下的组织安全实践，并检验其与建筑学徒工伤结果之间的关联。
采用1775名建筑学徒的横断面样本，评估了三种组织安全实践指标：承包商安全实践、管家安全实践和同事安全实践。每项安全实践指标均通过三个相似问题进行评估（即工作中的安全承诺、遵守规定或推荐的安全工作规范以及纠正不安全的工作规范）；回答的总和平均分在1至4之间，分数越高表明安全实践越差。结果变量包括四种肌肉骨骼疼痛（即颈部、肩部、手部和背部疼痛）的患病率以及与工伤相关的缺勤情况。
在调整分析中，承包商安全实践与手部疼痛（比值比：1.27，95%置信区间：1.04，1.54）和背部疼痛（比值比：1.40，95%置信区间：1.17，1.68）均相关；同事安全实践与背部疼痛（比值比：1.42，95%置信区间：1.18，1.71）和与工伤相关的缺勤情况（比值比：1.36，95%置信区间：1.11，1.67）有关。在一项同时纳入所有三种安全实践指标的分析中，同事安全实践与工伤相关缺勤之间的关联仍然显著（比值比：1.68，95%置信区间：1.20，2.37），而所有其他关联均变得不显著。
本研究表明，组织安全实践，尤其是同事安全实践，与建筑学徒的工伤结果相关。
