New diabetes cases in expanded-Medicaid states much higher than other states; 46,000 new Ky. Medicaid clients got screened

New diabetes cases among poor Americans are much more numerous in Kentucky and other states that have embraced the Patient Protection and Affordable Care Act, a medical testing company has found. The diagnoses rose 23 percent in the Obamacare states and barely rose in the others, apparently because state Medicaid programs are encouraging screening for diabetes.

Quest Diagnostics conducted the study by analyzing laboratory test results from all 50 states and the District of Columbia in its large database over two six-month periods, Sabrina Tavernise reports for The New York Times. The authors determined that because in January 2014, 26 states and the District of Columbia had expanded Medicaid and 24 had not, it was a good time to conduct this study, which is reported in the journal Diabetes Care.

The research team used the results of the basic test for diabetes, which measures a form of hemoglobin that has interacted with glucose, A1c. “In the states that expanded Medicaid, the number of Medicaid enrollees with newly identified diabetes rose by 23 percent, to 18,020 in the first six months of 2014, from 14,625 in the same period in 2013,” Tavernise reports. “The diagnosis rose by only 0.4 percent — to 11,653 from 11,612 — in the states that did not expand Medicaid.”

A Kentucky study indicates that more screening isn’t the only reason for such numbers; the Medicaid expansion population appears to be more susceptible to diabetes than normal.

The study by Deloitte Consulting found that chronic conditions, including diabetes, were more than twice as prevalent in the expansion population than other people of the same age and gender who were on Medicaid before it expanded. That comparative group was considered to be the group most similar to the Medicaid expansion population, since the state lacks historical data for the expansion group.
