Despite an intensive focus on workers' health during recent decades, the prevalence of work-related diseases remains unchanged in Denmark and internationally. Therefore, USA and Australian researchers have initiated new paradigms for integration of health promotion, prevention of work-related disease, and organization of work. Inspired by the Australian WorkHealth Improvement Network program (WIN), this paper describes the background, design, intervention methodologies, and evaluation methods of an Integrated Approach to Health, Wellbeing, and Productivity at Work (ITASPA) intervention aiming to prevent work-related injuries and diseases and promote the health, safety, and wellbeing of the worker.
Using a stepped wedge design, worksites will be enrolled at baseline and offered the intervention starting at different times. Data will be collected at baseline, before the off-set of the intervention, and after each implementation period. The effect evaluation will be based on a mixed-methods approach. The qualitative data are based on semi-structured interviews and focus groups. The quantitative data consists of questionnaires, anthropometrics, and resting blood pressure and will be analyzed based on the intention-to-treat principle in linear mixed models with random slope and intercept.
Integrated interventions are shown to increase overall health and safety at worksites more effectively and rapidly than more narrowly focused programs. Still, previous integrated interventions are lacking successful implementation. In ITASPA, the effects of the intervention is tested in a strong scientific mixed-methods design. Thus, the ITASPA project contributes to the knowledge about what characterizes a best practice for the implementation of integrated worksite interventions.
ITASPA is retrospectively registered in Clinicaltrials.gov on May 19, 2023 (NCT05866978).
尽管近几十年来人们高度关注劳动者健康，但丹麦和国际上与工作相关的疾病的患病率仍保持不变。因此，美国和澳大利亚的研究人员已经开创了新的范式，将健康促进、预防与工作相关的疾病以及组织工作相结合。受澳大利亚 WorkHealth 改善网络计划（WIN）的启发，本文描述了旨在预防与工作相关的伤害和疾病以及促进工人健康、安全和福祉的综合健康、福利和工作生产力方法（ITASPA）干预措施的背景、设计、干预方法和评估方法。
使用阶梯式楔形设计，将在基线时招募工作场所，并在不同时间开始提供干预措施。将在基线、干预开始前和每个实施阶段后收集数据。效果评估将基于混合方法。定性数据基于半结构化访谈和焦点小组。定量数据包括问卷、人体测量学和静息血压，将根据意向治疗原则，在具有随机斜率和截距的线性混合模型中进行分析。
综合干预措施已被证明比更狭义的方案更有效地、更迅速地提高工作场所的整体健康和安全。尽管如此，以前的综合干预措施都缺乏成功的实施。在 ITASPA 中，干预的效果将在一个强大的科学混合方法设计中进行测试。因此，ITASPA 项目有助于了解什么是综合工作场所干预实施的最佳实践特征。
ITASPA 于 2023 年 5 月 19 日（NCT05866978）在 Clinicaltrials.gov 上进行了回顾性注册。
