Despite major investment, health information technology (HIT) implementation often tends to fail. One of the reasons for HIT implementation failure is poor leadership in healthcare organisations, and thus, more research is needed on leaders' roles in HIT implementation. The aim of the review was to identify the role of healthcare leaders in HIT implementation. A scoping review with content analysis was conducted using a five-step framework defined by Arksey and O'Malley. Database searches were performed using CINAHL, Business Source Complete, ProQuest, Scopus and Web of Science. The included studies were written either in English or Finnish, published between 2000 and 2019, focused on HIT implementation and contained leadership insight given by various informants. In total, 16 studies were included. The roles of healthcare leaders were identified as supporter, change manager, advocate, project manager, manager, facilitator and champion. Identifying healthcare leaders' roles in HIT implementation may allow us to take a step closer to successful HIT implementation. Yet, it seems that healthcare leaders cannot fully realise these identified roles and their understanding of HIT needs enforcement. Also, healthcare leaders seem to need more support when actively participating in HIT implementation.
