Abstract

Rapid implementation of remote continuous glucose monitoring (CGM) is occurring across hospitals during the coronavirus disease 2019 (COVID-19) pandemic. Despite limited experience, the U.S. Food and Drug Administration is not objecting to the inpatient use of CGM to limit the exposure of health care workers to severe acute respiratory syndrome coronavirus 2 and to reduce the waste of personal protective equipment (1). Recent efforts in non–intensive care unit (ICU) patients suggest that CGM devices are accurate in the inpatient setting and can help monitor patients remotely (2,3). In addition, two recent small trials enrolling non-ICU patients confirm the feasibility of using remote real-time CGM in the hospital (4,5). The accuracy of sensors, however, may be affected during various conditions that have not been well studied (i.e., MRI, surgery, shock requiring vasopressor therapy, hypoxia) (1). To mitigate potential CGM inaccuracy, a hybrid approach using real-time CGM with periodic point-of-care (POC) validation has been suggested (1). We report here on the likely loss of sensor signal during cardiac surgery and potential loss of accuracy in the operating room (OR). We also report on the accuracy of sensors that recovered immediately after surgery during critical illness. We evaluated the performance of sensors in adults without diabetes undergoing scheduled or urgent coronary artery bypass surgery (CABG). We excluded …

  • In hospitalized patients monitored with capillary glucose before meals and at bedtime, about 45% experience asymptomatic hypoglycemia.

    “Prospective observational studies, using the current standard of care of checking capillary glucose before meals and at bedtime, have shown that about 45% of persons experience asymptomatic hypoglycemia events.1387,1388”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [1387]

    The paper’s main text reports sensor accuracy in 15 adults undergoing coronary artery bypass surgery, not the frequency of asymptomatic hypoglycemia in hospitalized patients. Searches for “45% asymptomatic hypoglycemia before meals and at bedtime” and “asymptomatic hypoglycemia capillary glucose monitoring hospitalized patients” found no passage addressing that estimate or monitoring schedule. No page numbers are available in our copy. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
