Researchers analyzing 15.8 million electronic health records contributed by 11 integrated health plans identified nearly 1.1 million people as having diabetes, and these patients' de-identified information is now part of a diabetes registry created by the plans.
The registry is the focus of an article in the latest issue of the Centers for Disease Control and Prevention's Preventing Chronic Disease journal.
The health plans, combining their patients' de-identified electronic health records into a database, identified diabetic individuals by analyzing inpatient and outpatient diagnosis codes, laboratory test results and pharmaceutical distributions. The individuals who met the researchers' diabetes criteria had been diagnosed with diabetes or had received a diabetes drug or posted elevated blood glucose levels in two separate tests, according to a news release from Kaiser Permanente, which has six regions participating in the program. The patients' information was used to form a diabetes registry called Surveillance, Prevention and Management of Diabetes Mellitus DataLink, or Supreme-DM DataLink.
