Stony Brook University32 enrolled

Overview

The purpose of this study is to analyze the efficacy and accuracy of real-time continuous glucose monitoring devices (rtCGM) in patients with Type 2 diabetes undergoing inpatient elective hip or knee surgery in the pre-, peri-, and post-operative setting at Stony Brook University Hospital (SBUH).

Interventions

Dexcom G6 Pro Continuous Glucose Monitor (CGM)DEVICE

A DexCom G6 CGM will be implanted on the subject's abdomen contralateral to the surgical site (i.e. left abdomen for right knee or right hip replacements) no less than 30 cm from the surgical site. This CGM shall be termed "primary" for study purposes. Subjects will wear the primary DexCom G6 CGM for the entirety of the following 10-day timeline: 3/4-days pre-operative, day of hip or knee replacement surgery, and 5/6-day postoperative recovery. A second CGM will be implanted in subjects postoperatively while in the Post Anesthesia Care Unit (PACU). This CGM, termed "secondary" for study purposes, will be implanted immediately adjacent to the primary CGM. Subjects will wear the secondary DexCom CGM for the 7 days: day of hip or knee replacement surgery (postoperatively) and 5/6-day postoperative recovery.

Outcomes

Primary Outcomes

Accuracy of Real-Time Continuous Glucose Monitoring

Analyze data from real-time continuous glucose monitoring and point-of-care glucose monitoring (POC-BG). rtCGM data will be matched and compared to POC-BG collected for standard clinical care in the pre-op and post-op settings (i.e. mealtimes, bedtime, and every 6 hours).

Time frame: 10 days

Secondary Outcomes

Interference of Intraoperative Electrocautery on Real-Time Continuous Glucose Monitoring

Analyze intraoperative rtCGM. Electrocautery, a common surgical technique using electrical current to mitigate bleeding by thermal damage of tissue, may emit electrical pulses which adversely interfere with the measurement and/or data transmission of the rtCGM device. All data points collected during the 60-90-minute operative window will be analyzed for interference, aberrant, or missing values.

Time frame: 60-90 minutes

Assess Irreversible Damage/Interference of Real-Time Continuous Glucose Monitoring Devices Caused by Electrocautery

Assess irreversible damage/interference of rtCGMs caused by electrocautery. In the postoperative setting, a second rtCGM will be implanted on patients. Data sets between the two rtCGMs will be analyzed for statistically significant mean absolute relative difference (MARD).

Time frame: 6-7 days
