The overall goal of this research study is to estimate the sex-specific incidence of hospitalization or emergency department visit for severe complications of urinary tract infections, defined as pyelonephritis and urosepsis, in patients who are prescribed dapagliflozin compared to patients prescribed other specific oral antidiabetic drugs. Dapagliflozin and other antidiabetic drugs are used to treat type 2 diabetes mellitus. Because of the mechanism of action for dapagliflozin and results from small safety monitoring studies, there is interest in further evaluating the safety of dapagliflozin in large populations.
