BACKGROUND: Hospital mergers in Capital Region are an ongoing process decided from the politicians. The overall aim is to centralize specialties to the hospitals and create super hospitals that can serve the inhabitants in the region better. The aim of this study was to see how action research could contribute with redefining the merging process into something more satisfying and beneficial for the radiographers. METHODS: This research was conducted in the time period of primo January to primo May 2018 at the Medical Imaging Department, Bispebjerg & Frederiksberg hospitals, Copenhagen Denmark. In collaboration with the managers and radiographers the research is based on qualitative methods with use of Action Research (AR) as the overall approach and hereby semi-structured interviews and participant observations serve as a foundation for diagnosing current problems in the organization. 12 in-depth interviews in situ was carried out while participant observations were enacted throughout several weeks. Lastly, I attended a theme-meeting where AR was intended to be used actively by planning actions to be carried out in the organization in collaboration with the radiographers and management. RESULTS: With use of AR and its phases I identified the radiographers’ social interests and with help from my empirical data I diagnosed some current problems at BFH. At a theme-meeting a proposed solution drawn from AR was presented to the manager and radiographers at the meeting. Furthermore, I outline recommendations to hospital mergers that needs to be taken into consideration for a democratic merger process to be enacted. CONCLUSION: I conclude that a democratic development in hospital mergers requires employee involvement and transparency to the changes related to the merger. The negative perceptions from the employees of the merger can be transformed if their voices are heard and management involve them in the decision-making.
