The Patient with Non-Pregnancy-Associated Vaginal Bleeding.

Abnormal uterine bleeding (AUB) unrelated to pregnancy affects 20% to 30% of women at some point in life and is a common emergency department (ED) and urgent care (UC) presentation. AUB is a complex condition with extensive terminology, broad differential diagnosis, and numerous treatment options, yet few published evidence-based guidelines. In the ED or UC setting most affected patients are often more frustrated than acutely ill. These factors can make for a challenging patient encounter in the EC/UC setting. This article reviews acute and chronic AUB in the nonpregnant patient and suggests a simplified approach for its evaluation and management.
