When we set out to build our vision and future, we connected with and heard from our community - patients, families, visitors, physicians, staff and volunteers. Our plan to create a new kind of health care for a healthier community means advancing health across the hospital, the system and the community and is built on an inter-connected system of care organized around patients and leaving no one behind. Recognizing this mission could not be realized without also assessing and investing in our internal practices, culture and processes we are building an organization where everyone at THP feels they belong, their voice matters, and contributes to our collective success. We commit to making systemic fairness a reality for all and are working to ensure that the community we serve is reflected at all levels, and in all professions at THP. Diversity is our strength and we recognize and value teaching and learning we all contribute and benefit from in our environment; our unique lived experiences matter and shape our actions and behaviors. In becoming an antiracist organization, we acknowledge the existence of oppression, racism, bias and complicity, and we have been working steadily to make changes in the way we work to dismantle these barriers. This includes developing and realizing an action plan to advance racial equity and embed anti-racism accountability across IBH, starting with our anti-Black racism priority initiative.
