Acute Kidney Injury in Patients on Dapagliflozin and Other Antidiabetic Medications
Study Details
Study Description
Brief Summary
To compare, by insulin use at the index date, the incidence of hospitalization for acute kidney injury (AKI) among patients with type 2 diabetes mellitus who are new users of dapagliflozin with those who are new users of antidiabetic drugs (ADs) in classes other than sodium-glucose cotransporter 2 (SGLT2) inhibitors, insulin monotherapy, metformin monotherapy, or sulfonylurea monotherapy

Detailed Description
The overall goal of this research study is to estimate the risk of hospitalization for acute kidney injury 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.
The study will be implemented in three administrative health care data sources in two countries: in the United Kingdom, the Clinical Practice Research Datalink (CPRD); and in the United States, the Centers for Medicare and Medicaid Services (CMS) Medicare databases and the HealthCore Integrated Research Database (HIRDSM). Individuals in the databases will be included in the study if they meet the following age criteria; 18 years and older (CPRD and HIRD), or 65 years or older (Medicare); and if they did not have type 1 diabetes, are new users of one of the study drugs and meet the criteria of at least 180 days of electronic data before their first prescription of the study drug. The study period starts July 1, 2013 in CPRD, January 1, 2014 in PHARMO and January 9, 2014 in the United States data sources, and will end at the latest available data at each database at the time of analysis.

Outcome Measures
Primary Outcome Measures
- Incidence of Acute Kidney injury (AKI) [Day after index date up to six years]
Patients will be followed from their index date (date of first study drug prescription or dispensing) until they experience one of the following: an event under study, end of time at risk for index medication, death, addition of a non-dapagliflozin SGLT2 inhibitor, termination of health plan, transfer out of the GP practice, or end of the study period up to six years.
