The Complete Rockall Score is a clinical calculator used to predict the risk of mortality due to upper gastrointestinal (GI) bleeding. It is applicable to patients who have been diagnosed with upper GI bleeding, regardless of the underlying cause. The score is calculated based on several factors including age, shock, comorbidity, diagnosis, and endoscopic findings. The higher the score, the higher the risk of mortality. 

The clinical utility of the Complete Rockall Score is to aid in clinical decision-making by stratifying patients based on their risk of mortality. This can help guide treatment strategies, such as the need for hospital admission, intensive care, or endoscopic intervention. 

There are no specific exclusion criteria for the use of the Complete Rockall Score. However, it should be noted that this score is not applicable to patients with lower GI bleeding or those without a confirmed diagnosis of upper GI bleeding.
