CGM in Patients With ED's — CGM  

Anorexia Nervosa Restricting Type Clinical Trial

Official title: Glucose Monitoring in Patients With Eating Disorders: A Pilot Study

Status Enrolling by invitation

Clinical Trial Summary

To determine the accuracy of continuous glucose monitoring (CGM) with point of care (POC) fingerstick glucose monitoring and venous blood glucose in patients with eating disorders, specifically anorexia nervosa, restricting subtype (AN-R); avoidant/restrictive food intake disorder (ARFID); and anorexia nervosa, binge/purge subtype (AN-BP).

Clinical Trial Description

It is the experience of the treatment team at ACUTE Center for Eating Disorders and Severe Malnutrition that POC fingerstick testing can be inaccurate in patients when POC fingerstick testing is compared to serum glucose values. However, this has not been formally studied. This study seeks to define the accuracy of POC fingerstick testing and CGM as compared to blood serum glucose monitoring via phlebotomy. It also seeks to better understand the frequency of hypo- and hyperglycemia in this population using continuous glucose monitoring during the first 10 days of admission. Ideally, an accurate method of monitoring glucose values in this population beside phlebotomy draws needs to be established. Blood will be drawn shortly after participants admission to the unit as part of usual care and will continue to be drawn daily as usual care for the next 5 days. Patient blood sugar will be checked daily using POC finger sticks until hypoglycemia resolves. If patient choose to participate in this study, the investigators will do additional POC testing on days 6 and 8 POC finger sticks will be done 30-minutes post breakfast/lunch/dinner. On the same day the patient agrees to be in this study, the patient will have a Dexcom CGM placed to the back of their arm, or on another area of the body depending on the recommendation from the manufacturer (DEXCOM). Patient will wear the CGM for the full 10 days that the study is being conducted. Patient will also be asked to complete a simple log regarding the date and time the patient received post Breakfast/lunch/dinner POC tests on days 6 and 8. The patient may ask the PSCA Patient Safety Care Attendant (PSCA) to assist patient with this task. Data received from the Dexcom device will automatically be uploaded to the Dexcom cloud. Only the research statistician will have access to these data. Staff from Dexcom do not have access to these data. ;
