Retrospective cohort study evaluating patterns of use, comparative effectiveness, and safety of oral diabetes medications for adults with type 2 diabetes
The initial proof of concept project for DARTNet, designed to illustrate the similarities and differences of secondary data from large insurance-based claims datasets to EHR data extraction via DARTNet. Specific design elements included an OCER algorithm for comparing monotherapy to combination therapy for oral hypoglycemic drugs, and then illustrating that comparable data could be extracted using DARTNet, with the addition of patient reported data.
The first DARTNet "certification" was conducted to assure the integrity of data extracted. The first DARTNet CDR was developed, along with a defined protocol for the OCER study.
