Introduction The purpose of workplace surveys is to investigate the hazards, exposures and strains of the work environment and evaluate their impact on employees’ health and safety. In addition, occupational health service (OHS) propose actions to improve health and safety at work. The Occupational Health Act (1383/2001) sets the framework for systematic and target-oriented cooperation between OHS, employers and employees. An essential component in cooperation is the exchange of relevant data.

Methods We used the Delphi method to evaluate which data is considered relevant for information exchange in workplace surveys and how it should be documented in the information systems. Altogether thirty-seven OH physicians, OH nurses, OH physiotherapists and OH psychologists participated in the three rounds of the survey. The response rates were 76%, 73% and 73%, respectively. The data was analysed with the content analysis.

Result The most relevant data for information exchange between OHS and workplace in the workplace surveys were work-related health and safety risks, work load and recovery factors, recommendations for further actions and the information about the work environment, staff, professional titles and changes in the workplace.

Discussion OHS professionals use regularly information systems for documenting workplace survey data. The way the data is stored and made available in the information systems do not support enough planning and monitoring of the OHS activities and collaboration with the workplace. In order to improve the situation, better understanding of what is the relevant data for information exchange and the way the data should be structured, is needed.
