Government Coverage: Provides funding for a new pump every 5 years. Annual Supplies Cost: Around $2,400/year for insulin pump supplies. Pump Features Tubing: The pump holds 200-300 units of insulin. Reservoir Filling: The insulin pump requires refilling the pod reservoir every 3 days. Insulin Delivery Pumps uses Fast-Acting Insulin: Insulin pumps only deliver fast-acting insulin and provide small doses every few minutes to keep the patient’s blood sugar within a desired range with minimal intervention. Insulin Sets Different types of infusion sets are available for varying body types. Infusion sets contain Teflon, but alternatives are available for patients with Teflon allergies. Integration Pumps can integrate with continuous glucose monitors like the Dexcom G6 or Dexcom G7 for real-time blood glucose monitoring and automatic adjustments. Insulin Pump BRANDS and features Tandem ○ Originally designed as a dual-chamber pump (insulin and glucagon), but now only delivers insulin. ○ Integrated with Dexcom G6 for continuous glucose monitoring. ○ Infusion Sets: Different types cater to various body types and are rechargeable. Medtronic Pumps: ○ Medtronic manufactures and makes everything in-house (including infusion sets). ○ Uses their own sensory monitoring system (Enlite), but it is not as accurate as Dexcom sensors. ○ Infusion Sets: Battery-powered.  Omnipod: ○ Tubeless, waterproof insulin pump. ○ Provides continuous insulin delivery for up to 72 hours (3 days). ○ Patients must deactivate the old pod before placing a new one. ○ Waterproof and tangle-proof, making it more convenient for active individuals. Ypsomed (YpsoPump): ○ A newer player in the insulin pump market. ○ Can be controlled via an app for convenience. Key Considerations for Diabetes Devices Pregnancy with Diabetes: Managing diabetes during pregnancy requires extra care and monitoring, especially with insulin and glucose levels. Infusion Sets and Teflon Concerns: Ensure that alternative infusion sets are available for patients with allergies to Teflon. Pump Maintenance: Regular pump checks are necessary, including replacing the pod or infusion set every few days (depending on the system). 65 years old can apply for grant just under $180/year  CONTOUR NEXT GEN Contour Next Gen Glucose Meter Brand: Ascensia Pharmacist Recommendation: #1 pharmacist recommended blood glucose meter brand. Key Features: 1. No Initial Setup: Unlike other meters that require calibration, the Contour Next Gen does not need initial setup, making it ready for immediate use. 2. Accuracy: ○ Measurement accuracy is 5.3%, which ensures reliable glucose readings for patients. 3. Smart Light Indicator (Guiding Light): ○ The meter includes a color-changing light indicator to help patients interpret their results: Green: Indicates a glucose level between 5-10 mmol/L (within normal range). Yellow: Indicates a glucose level above 10 mmol/L (hyperglycemia). Red: Indicates a glucose level below 5 mmol/L (hypoglycemia). 4. Reusing Test Strips: ○ Test Strips: Patients can reuse the test strips within 60 seconds if the initial blood sample is insufficient. This feature allows for applying more blood instead of wasting a new strip. 5. Glucose Reading Skew: ○ Certain substances, like citrus, may skew glucose readings. To avoid this, patients are advised to wash their hands or use alcohol wipes before testing. 6. Lancets: ○ The lancets for the Contour Next Gen are colorful for easy identification. Usage Tips: Accuracy with Blood Sample: If there is insufficient blood on the strip, patients have up to 60 seconds to apply more blood, helping to prevent errors and waste of strips. Hygiene: Always wash hands thoroughly or use an alcohol wipe to ensure accurate results and avoid interference from foods (like citrus) or contaminants.  ONE TOUCH VERIO REFLECT 1-7 depth setting The device may offer tips, reminders, or advice, helping users stay on track with their diabetes management Emoji Feature ○ uniquely incorporate emojis to display blood glucose results or the status of the user's health. ○ Unique to OneTouch provide results in under five seconds store test results, allowing users to track their blood sugar over time and share data with healthcare providers. ACCU CHEK lancing device offers several convenient features for blood glucose testing. Guide me light: The light feature helps illuminate the area around the lancet, making it easier to see and perform the fingerstick, especially in low-light conditions. Shoots Out Lancet with a Button: The lancet is automatically ejected when you press a button, making the process quick and easy. Depth Adjustment in Half-Increments (Up to 5) Indicator (Yellow When Loaded, Clear When Not) ○ provides a clear visual cue to show that the device is ready to use, FREESTYLE LIBRE 2 Placement Site: The sensor should be placed on the back of the upper arm. It is no longer indicated for use anywhere else on the body. Preparation: Clean the area with an alcohol swab before placing the sensor to remove any oils, even after a shower. Sensor Application Process ○ Set up the applicator on a flat surface to ensure accuracy. ○ Align the applicator with the sensor by matching the indicated lines. Once aligned, press the applicator down firmly against the arm to insert the sensor.  Reader Device: The FreeStyle Libre 2 contains a reader that you tap against the sensor to collect data. This is a great option for patients who don’t have a compatible smartphone. ○ iphone : scan on top of phone ○ Android : scan in the middle of phone ○ Scanning Frequency: The sensor should be scanned every 8 hours. After 8 hours, the system will display a complete glucose graph. ○ Out of Range: If the phone is out of range, the sensor needs to be scanned again to get updated data. Device Compatibility: The sensor can only be paired with one device at a time (either the app or the reader). App Features: The app provides real-time data and glucose tracking. Reader Features: The reader can be used for data collection if the app is not compatible or preferred. Warm-Up Time: 1 hour Trend Arrows: The device shows trend arrows that reflect the direction of blood glucose levels: ○ Up Arrow: Glucose level is rising at a rate of 1 mmol/L every 10 minutes. ○ Straight Arrow: Glucose level is stable, with a change of less than 0.06 mmol/L per minute. ○ Flat Arrow: Glucose level is not changing significantly. Data Transmission: You only need Wi-Fi to download the app, as data transmission itself does not require Wi-Fi. Sharing Data: You can share glucose data with friends, family, or healthcare providers. LibreView: A software that allows data sharing and review of glucose trends. My Freestyle Program: A patient support program to assist with diabetes management. Coverage ○ Private Insurance: The sensor is covered by programs such as ODB Plus, ODB 65+, Trillium, and ODSB. Private insurance may also cover it even if the patient is not using insulin. Don’t necessarily have to be on insulin to be covered Sensor Lifespan: 14 days Water Resistance: The sensor can withstand up to 3 meters of water for no longer than 1 hour. Showers and hot tubs are fine for use with the sensor. Glucose Control Insights ○ A1C vs. Glucose Variability: Patients may have the same A1C but experience different glucose variability. The A1C provides an average measure of blood glucose levels over time, but it doesn't reflect fluctuations in daily glucose levels. ○ Better Glucose Monitoring: The Libre 2 provides more continuous and real-time data, offering a more complete picture of glucose control than A1C alone.
