CGM in hospitals helps detect hypoglycemia on wards
Regarding the increase of inpatient CGM (continuous glucose monitoring) prompted by the need to minimize patient exposure of nursing staff during the pandemic and the relaxing of Food and Drug Administration rules about its use, Dr. Klonoff said this phenomenon has led to two other positive developments.
“For FDA, it’s actually an opportunity to see some data collected. To do a clinical trial [prior to] March 2020 you had to go through a lot of processes to do a study. Once it becomes part of clinical care, then you can collect a lot of data,” he noted.
Moreover, Dr. Klonoff said there’s an important new area where hospital use of CGM is emerging: detection of hypoglycemia on wards.
“When a patient is in the ICU, if they become hypoglycemic or hyperglycemic it will likely be detected. But on the wards, they simply don’t get the same attention. Just about every doctor has had a case where somebody drifted into hypoglycemia that wasn’t recognized and maybe even died,” he explained.
If, however, “patients treated with insulin could all have CGMs that would be so useful. It would send out an alarm. A lot of times people don’t eat when you think they will. Suddenly the insulin dose is inappropriate and the nurse didn’t realize. Or, if IV nutrition stops and the insulin is given [it can be harmful].”
Another example, he said, is a common scenario when insulin is used in patients who are treated with steroids. “They need insulin, but then the steroid is decreased and the insulin dose isn’t decreased fast enough. All those situations can be helped with CGM.”
Overall, he concluded, COVID-19 has provided many lessons, which are “expanding our horizons.”
Ms. Zhang has reported no relevant financial relationships. Dr. Klonoff has reported being a consultant for Dexcom, EOFlow, Fractyl, Lifecare, Novo Nordisk, Roche Diagnostics, Samsung, and Thirdwayv.
