CGMs - Not SARS Cov-2 Related

Good afternoon!
My inpatient diabetes team is asking for feedback about inpatients who refuse finger stick blood sugars because they have a CGM.
Does anyone have a policy for these patients/situations?
This is not related to the EUA for CGMs during the pandemic.
Thank you!

Great question. I have been wondering if it is ok to use CGM’s in the hospital in place of pOC glucose testing. I have researched this and cannot find any information
regarding the accuracy and legality of using it in a hospital setting.
They are not FDA approved for hospital use and might not ever be. They are fairly inaccurate compared to whole blood samples. On the low and high ends the CV is as much as 70%.
My Inpatient Diab. team is using them under EUA for covid patients but they are only using them to trend the patient. They know they are discrepant. (and they got a separate CLIA for it too)
Knowing that, they have been refusing to let patients use theirs but since they are gaining popularity more people are refusing finger sticks.
Amber, hi!
Did the inpatient diabetes team get a CLIA for this ('study'?) work because they were also performing fingersticks (requiring a CLIA for clinical use) as well as whole blood samples and the continuous glucose measurements (not requiring a CLIA)?
Thanks
I would not say CGMs are innacurate and discrepant. You cannot compare apples and oranges because CGM measure glucose in tissue fluid. It cannot be compared to the serum or plasma in the blood, Tissue fluid does not match the plasma glucose level at one point in time. If the fingerstick read 100 at 7AM, the CGM will read 100 at 715AM.That is how it was explained to me.
It is not FDA approved for in patient hospital use yet but I think we will see it in use in the next 5-10 years. More and more diabetics are wearing those CGMs. It is useful for clinical settings rather than lab testing. The doctor can see the peaks and valleys of the patient glucose, Unless you do fingerstick every 15-30 minutes you would not see the same picture. Of course the patients hate being poked that many times
Peggy,
They got their own CLIA for the EUA use of CGMs during the pandemic because the Lab, whose CLIA they are currently under, didn't want to deal with it. But understand when the pandemic ends so does the use of them. This CLIA would not apply to the issue of patient refusals.
Our issue is we've seen an increase in patients refusing finger stick blood sugars because the have a CGM. We are wondering if other facilities have a problem with patients refusing the finger sticks and how these are handled.
