The communities for which healthcare organizations operate are rapidly diversifying. Not only do they provide care for a diverse community of patients and families, but their workforce is also growing more diverse. It is incumbent on healthcare organizations and their leaders to both understand and embrace the needs of diverse populations. Their ability to respond to the needs and preferences of a broader customer base will be critical to their financial and operational survival, but they first must understand what their implicit biases are to do that. The goal of the session is for leaders to understand and recognize internal biases both conscious and unconscious. This program will focus on the healthcare leader’s personal recognition of internal bias and its impact on decisions in the organization. The impact of the healthcare leaders’ ability to recognize biases in areas such as employment and policy decision making will lead to increased diversity in individuals holding leadership positions and will help us better serve our patients and communities.
