However, some ED patients have abnormal bleeding due to impaired hemostasis. Identifying these patients requires attention to the history and physical findings.2,3,4 Generally speaking, when patients have spontaneous bleeding from multiple sites, bleeding from untraumatized sites, delayed bleeding several hours after trauma, and bleeding into deep tissues or joints, the possibility of a bleeding disorder should be considered.
