This paper aimed to contribute to the development of a sociotechnical understanding and a robust implementation strategy of integration in health care by analysing how clinical practice and the history of existing systems play a crucial role in integration efforts. The authors use the implementation and integration of the large-scale Electronic Medication Management System (EMMS) MetaVision in the Health Authority Northern Norway, as an empirical example, with a focus on the integration challenges between the EMMS and the existing Electronic Patient Record (EPR) system. The MetaVision EMMS covers emergency units, intensive care and anaesthesia departments, operating rooms, outpatient clinics and clinical wards. The authors found that integration involves a lot of socio-technical and organisational issues that need to be addressed and highlight the importance of considering different stakeholders’ perspective as well as routine changes when large-scale integration projects are planned.
