Evaluation and management of occult and obscure gastrointestinal bleeding.

Gastrointestinal (GI) bleeding is a commonly encountered primary care clinical challenge. The AGA Medical Position Statement: Evaluation and Management of Occult and Obscure Gastrointestinal Bleeding, reviewed in this month's clinical practice guideline column, summarizes recommendations for the initial diagnostic approach and management for occult bleeding, as well as the subsequent diagnostic and management approach for obscure bleeding. The recommendations have applicability in primary care as nurse practitioners (NPs) assess the cause of occult bleeding and consult with specialists when obscure bleeding occurs.
