Study: Most U.S. Adults with Diabetes are Properly Diagnosed
The proportion of diabetes cases that go undiagnosed in the U.S. may be just 11%, much lower than previous, widely accepted estimates of one-quarter to one-third, a new study suggested.
The previous estimates were based on an analysis of national survey data that used only a single test to identify undiagnosed diabetes, but the new study used a second confirmatory test, as per guidelines from the American Diabetes Association (ADA), explained Elizabeth Selvin, PhD, of Johns Hopkins University in Baltimore, and colleagues.
The proportion of undiagnosed diabetes cases has also decreased over time, from 16% in 1988-1994 to the 11% figure in 2011-2014, they reported online in the Annals of Internal Medicine.
"Establishing the burden of undiagnosed diabetes is critical to monitoring public health efforts related to screening and diagnosis," Selvin's group wrote. "When a confirmatory definition is used, undiagnosed diabetes is a relatively small fraction of the total diabetes population; most U.S. adults with diabetes (about 90%) have received a diagnosis of the condition."
"If we're thinking about screening programs, these findings suggest that healthcare providers are doing a good job at diagnosing people when they're coming in contact with the healthcare system," Selvin said in a statement. "It's those people who are not coming in contact with the healthcare system that need to be a focus of our efforts to ensure cases of diabetes are not missed."
Selvin's group analyzed the same data that was used for the previous estimates, which were published by the CDC: the National Healt Continue reading
