Hyperglycemia is unequivocally associated with poor outcomes especially in hospitalized patients. The aim of this study therefore is to measure the occurrence of hyperglycemic events particularly in patients with T2DM requiring acute care and subsequent hospitalization with or without hypertension and describe the epidemiological features.
