When the devices erred, they tended to overestimate, rather than underestimate, blood-sugar levels, prompting the researchers to note that additional research is warranted, especially considering that people on dialysis tend to be at elevated risk for low blood sugar.
“Although we certainly need larger studies, I am encouraged that these factory-calibrated continuous glucose monitors may be reasonably accurate for patients on hemodialysis therapy,” Stumpf said. “CGM use for these patients could lead to improved glucose control, improved safety from life-threatening hypoglycemia and, very importantly, improved quality of life.”
Findings Published
The researchers have published their findings in the scientific journal Diabetes Care. The research team consisted of Orianne Villard, Marc D. Breton, Swati Rao, Mary K. Voelmle, Morgan R. Fuller, Helen E. Myers, Ryan K. McFadden, Zander S. Luke, Christian A. Wakeman, Mary Clancy-Oliveri, Ananda Basu and Stumpf. Breton receives research support from Tandem Diabetes, Dexcom and Novo Nordisk and serves as a consultant for Dexcom, Adocia and Air Liquide; he also has received speaker fees from Tandem Diabetes and Arecor. Voelmle is an employee of LifeScan Inc. and received research support from Medtronic and Insulet Corp.; she has been on a speaker panel for Abbott and Dexcom. Basu was a speaker for Zealand Pharmaceuticals.
Dexcom provided the devices used in the study but had no role in the data collection, analysis or findings. Additional support was provided by UVA and a grant from the Societe Francophone du Diabete.
