Clinical leaders at the forefront of change in health-care systems: advantages and issues. Lessons learned from the evaluation of the implementation of an integrated oncological services network.

Based on lessons learned from the evaluation of the implementation of an integrated oncological services network in Québec, this paper discusses the following question: to what extent is strong clinical leadership a propitious means of transforming health-care systems, especially when the change leads to significant evolution in inter-professional and inter-organizational relations? Through a qualitative case study, we analysed the exercising of leadership by studying over time the clinical leaders' initiatives while trying to understand the sources of influence, the nature of the tactics adopted and their consequences for the degree of integration of health services. This study seems to show that clinical leadership is effective but limited. We conclude that a constellation of clinical, administrative and political leaders found at different levels of the health-care system offers more promise of positive change for the health-care system.
