Name of the Procedure:

Continuous Noninvasive Glucose Monitoring Device Purchase (S1030)

Summary

This procedure involves the purchase and implementation of a continuous noninvasive glucose monitoring device that tracks blood glucose levels in real-time. It is designed for continuous use and provides data that can be interpreted by a physician to manage a patient's glucose levels more effectively.

Purpose

The device is meant to help manage diabetes by providing continuous, real-time glucose readings. This can help in maintaining blood glucose levels within a target range, thereby preventing both hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar). The ultimate goal is to improve the overall management of diabetes and prevent long-term complications.

Indications

• Patients diagnosed with diabetes mellitus (Type 1 or Type 2).
• Individuals who require continuous monitoring of their blood glucose levels due to hypoglycemia unawareness.
• Patients experiencing frequent fluctuations in blood glucose levels.
• Those who need detailed glucose data to adjust insulin dosages.

Preparation

• There is typically no special preparation required for the installation of the device.
• The patient might need to undergo a brief orientation session to understand how to use and maintain the device.
• Any pre-existing conditions that may affect the sensor's placement or function should be discussed with the healthcare provider.

Procedure Description

1. Device Setup: The continuous glucose monitor (CGM) includes a sensor, transmitter, and a receiver or smart device.
2. Sensor Insertion: A small sensor is usually placed on the skin using an adhesive patch.
3. Device Activation: The transmitter sends glucose data to the receiver or an app on the user's smartphone.
4. Data Collection: The device continuously tracks glucose levels and trends, sending real-time data for patient and physician review.
5. Routine Checks: The device may need routine calibration and sensor replacement as per the manufacturer's guidelines.

Duration

The initial setup and orientation typically take about 1-2 hours. The device then provides continuous monitoring 24/7.

Setting

• Outpatient clinic or physician’s office for initial setup and instruction.
• Home setting for continuous use and daily monitoring.

Personnel

• Diabetologist or endocrinologist for initial prescription and interpretation of glucose data.
• Nurse or diabetes educator for device setup and patient training.

Risks and Complications

• Skin irritation or allergic reaction at the sensor site.
• Sensor may become dislodged or malfunction.
• Data inaccuracies if the sensor is not calibrated correctly.

Benefits

• Continuous monitoring provides a comprehensive glucose profile.
• Alerts for hypo- or hyperglycemia, which can prompt timely intervention.
• Helps to better tailor insulin therapy and other treatments.
• May improve glycemic control and reduce the risk of diabetes-related complications.

Recovery

• No downtime required; patients can resume normal activities immediately after device setup.
• Periodic sensor replacement and occasional calibration might be needed.

Alternatives

• Fingerstick Blood Glucose Monitoring: Involves regular pricking of the fingers to test blood glucose levels.
  • Pros: Generally lower cost, no need for continuous wear.
  • Cons: Provides a snapshot rather than continuous data, might miss periods of hypo- or hyperglycemia.
• Intermittent Scanning CGM: Requires the user to scan the sensor for glucose readings.
  • Pros: Lower cost compared to continuous CGM.
  • Cons: Does not provide automatic alerts for high or low glucose levels.

Patient Experience

• A slight prick might be felt during sensor insertion; generally, it is well tolerated.
• Daily activities are typically unaffected; the adhesive patch keeps the device secure even during exercise.
• Any discomfort or concerns should be discussed with the healthcare provider for adjustments or care tips.
