Monitoreo continuo de glucosa en la unidad de cuidados intensivos
Monitoreo continuo de glucosa en la unidad de cuidados intensivos: validación e implementación
The aim of the proposed clinical trial is to study the use of the Dexcom G7 continuous glucose monitor (CGM) within the intensive care unit (ICU) environment. The overall goal is to validate the accuracy and practicality of the Dexcom G7 when used to assess glycemia in critically ill patients.

Descripción detallada
The specific goals are 1) to work with intensive care unit (ICU) staff, in a respiratory ICU setting, to determine how best to place and maintain Dexcom G7 continuous glucose monitors (CGMs) on patients and how to place recording devices and chargers in that environment, 2) download CGM readings to the Dexcom Dashboard in an analyzable format, and 3) to compare simultaneous CGM readings with glucose measurements obtained in the course of routine care as recorded in the electronic medical record. The primary analytical goal is the correlation of CGM glucose measurements with those obtained in the course of routine care. A secondary goal is to determine the frequency of device malfunctions that occur either as a result of device failure (e.g. it falls off) or adverse events (e.g. removal due to skin irritation).
Study subjects will be patients admitted to the 6-ICU UMass Memorial Medical Center (UMMMC) University Campus medical intensive care unit for any reason who have known diabetes or who are hyperglycemic (blood glucose concentration ≥200 mg/dL) with diabetes that was previously undiagnosed or unrecognized. All enrolled volunteers will have a Dexcom G7 CGM place on the skin according to manufacturer's specifications. The devices will remain in place for 10 days or until discharge from the ICU

Mean Absolute Relative Difference (MARD).
Periodo de tiempo: 6 months
|
Concordance of glucose concentration results obtained by standard test methods with those obtained nearly simultaneously by a continuous glucose monitoring device was assessed by Mean Absolute Relative Difference (MARD). The MARD is the average percentage difference between the continuous glucose monitor readings measured over 6 months and glucose concentration results obtained by near simultaneous (+/- 5 minutes) standard test methods was used to gauge the accuracy of the CGM in the ICU setting. Typical MARD values reported for CGMs in the outpatient setting average approximately 8%. Typical MARD values reported for CGMs other than the one used in this study n the ICU setting average approximately 12%. |

Clarke Error Grid
Periodo de tiempo: 6 months
|
Concordance of glucose concentration results obtained by standard test methods with those obtained nearly simultaneously by a continuous glucose monitoring device was assessed by Clarke Error Grid. The Clarke Error Grid plots of reference glucose values obtained by point-of-care fingerstick or laboratory determination (x-axis) against CGM values (y-axis). The grid is divided into 5 zones (A-E) that indicate clinical implications of CGM glucose measurements when compared to a "gold standard" Region A: Clinically accurate. Region B: Benign measurement error. Region C: Overcorrection error region CGM values suggest unnecessary treatment. Region D: Serious hypo- or hyperglycemia detection error region. Region E: Erroneous treatment region. CGM fails to detect potentially dangerous hypo- or hyperglycemia Ideally, all values are in Regions A and B. We report the percentage of correlated values that fall in each region. |
