Increase in colonic diverticular hemorrhage and confounding factors

Figure 2 Changes in the number of patients with colonic diverticular hemorrhage: Number of patients requiring hospitalization, requiring transfusion, and using antithrombotic drugs or nonsteroidal anti-inflammatory drugs (1995 to 2013). The number of patients with diverticular hemorrhage (DH) started to increase rapidly in 2003, and peaked in 2008. This was associated with an increase in the number of patients hospitalized, receiving blood transfusions, using antithrombotic drugs (ATDs), and using nonsteroidal anti-inflammatory drugs (NSAIDs).
