*4.2. The Significance of the Study in Comparison with Previous Implementation Research in Germany*

Compared with previous studies, this study has several special features. Most previous surveys, particularly those in Germany, were focused on workplace health promotion, while this study differentiates between four categories of workplace health management in order to gain detailed data on each category. The correlation between implementation grade and company size is already well evidenced by literature on Germany as well as other high-income countries [21,22,24–27,48–50]. In addition, our study enables the analysis of new relationships such as the correlation between implementation status and satisfaction of company representatives with their implementation status [30].

To get a holistic overview of the current situation of workplace health management, one must move on from the scope of our survey. It is not only important what companies do, but also how they do it and, first of all, to what extent health-related measures actually reach the employees. Subjective perceptions of working conditions and appreciation of employees by managers play an important role in employee health and well-being in companies, as has been shown for the prevention of psychological and psychosomatic disorders in employees in our recent research [44]. Therefore, further research should also integrate this dimension.
