Sentinel injuries are often the earliest warning signs of physical abuse and may precede more serious or fatal injury. This presentation will discuss the identification, evaluation, and clinical significance of sentinel injuries with emphasis on bruising, oral injuries, and other subtle findings that warrant careful assessment. Through through case-based discussion and evidence-based guidance attendees will develop a trauma informed approach to recognize sentinel injuries, effectively communicate to caregivers and community partners why these injuries elicit concern, and mitigate missed opportunities for intervention.
