Thursday, September 30, 2021 | Leong Centre with Health Equity Rounds for Orange Shirt Day: "Complex Care in a Colonial World: Health Equity Through Trauma-Informed, Culturally Safe Practice"

Indigenous children frequently present as complex cases for one major reason: because colonialism is not good for Indigenous people. Providing specialized care to people who have experienced colonization means using trauma-informed care and culturally safe care to prevent further harm. On these rounds, we will examine the various forms of trauma that have been researched and defined over the past four decades, the effects of trauma on Indigenous people and what this means for their engagement strategies and coping methods, the effects of trauma on Indigenous family structure and function, how trauma changes a survivor’s relationship with their physical body, and the effects of colonization on personal and collective agency. This session will also provide clinicians and other staff with concrete actions you can take to provide trauma-informed care and support Indigenous approaches to healing and wellness.
