For a number of years, members of the diabetes community have been creating systems to monitor blood glucose levels and infuse insulin automatically using computer algorithms. These systems, informally known as artificial pancreases, are often comprised of components that, while individually approved by the FDA, have not been tested for use together, according to Bloomberg.
The warning from the FDA was prompted by a report the agency received about a person using a DIY system who received too much insulin after getting “repeated incorrect high glucose values,” resulting in an insulin overdose the required medical attention. It is not clear, the FDA notes, whether the overdose resulted from inaccurate blood glucose values reported from an unauthorized sensor or from a software malfunction. The patient survived.
“Patient use of unauthorized diabetes-management devices, alone or along with other devices, could result in inaccurate glucose level readings or unsafe insulin dosing,” the FDA states. “These inaccuracies may lead to injuries requiring medical intervention, such as severe low blood sugar, coma, diabetic ketoacidosis — the buildup of acids in blood — and death.”
An FDA-approved artificial pancreas device — a hybrid closed loop system known as the MiniMed 670G — is manufactured by Medtronic.
