Optimizing Diabetes Management: 3 Layers of CGM Alerts

With diabetes, it’s extremely important to know where your blood glucose is, where it’s going, and how fast it’s getting there. Today, Kristin Baker, a CGM Product Specialist here at Medtronic, joins us to talk about three types of continuous glucose monitoring (CGM) alerts to help with that information – Threshold, Predictive, and Rate of Change alerts.

Have you ever had the odd feeling that someone was watching over you throughout the day? The feeling that at just the right moment, someone or something was stepping in at just the right time to help you avoid what could have been a disastrous situation?

For those using the MiniMed Paradigm REAL-Time Revel System or the Guardian REAL-Time CGM System, Continuous Glucose Monitoring (CGM) can in some cases act as a “Guardian Angel” – monitoring your glucose patterns and trends and stepping in to alert you to potential dangerous glucose events ahead so you can take action sooner. 

Our distinctive system offers you not one, not two, but three different types of protection from dangerous glucose levels by allowing you to set threshold, predictive, and rate of change alerts. 

Threshold Alerts: Notify you when your sensor glucose readings have reached or moved below or above the glucose limits you have programmed into your device. 

How It Helps -- Think about when you head out for your morning walk/run to get your day started. Let’s say half way in you start feeling crummy and stop to test. You notice you have a very low blood sugar and stop immediately to take action. When using Threshold alerts, you could have avoided stopping  your walk/run short by setting your low threshold alert and receiving an alert earlier on to warn you that you have reached your low sensor glucose limit and should consider confirming the reading with a fingerstick and taking action (i.e. having a snack or taking some glucose tabs).

Other facts about Low and High Threshold Alerts:
• You may set either the low or high limit or both with guidance from your healthcare team.
• You can set up to eight customizable Low and High limits for different periods of the day.

Predictive Alerts: Notify you to oncoming low or high glucose levels up to 30 minutes before they occur.

How It Helps -- Let’s say you always check your blood glucose before you get in your car to drive in to work or school, and things looks good. But during the drive, as you sense it, you experience a low blood glucose and have to pull over to treat it. How could you have known earlier? Well, when set in your device, predictive alerts could have alerted you 30 minutes before that low glucose level occurred, allowing you to confirm the reading with a fingerstick and consider taking action before you step in the car.

Other facts about Low and High Predictive Alerts:
• You may set a Predictive Low, Predictive High, both or neither with guidance from your healthcare team. 
• Can be set anywhere between 5 to 30 minutes.

Rate of Change Alerts: Notify you about how fast sensor glucose values rise or fall outside your glucose rate of change limits.

How It Helps -- Its lunchtime and you are having a great conversation with friends about your plans for the weekend. Suddenly, the break is over and you rush back to work or class, but you realize you forgot to give yourself a bolus for your meal and now you are concerned about high glucose levels later that afternoon. What do you do? Give your meal bolus and use the rate of change alerts on your CGM device to help you closely monitor the trends of your glucose levels. It will alert you of rapid changes in your glucose levels so you can have more information for further action.

Other facts about Rate-of-Change Alerts:
• You may set a Fall Rate, Rise Rate, both or neither with guidance from your healthcare team. 
• The Rate of Change Alerts can be set from 1.1 to 5.0 mg/dL/minute.
• Alert displays as single or double arrows on your screen

Now, we can’t promise that the Medtronic CGM devices are going to step in and act as your guardian throughout all aspects of your life, but it can offer some additional support when it comes to managing your diabetes. If you have one of these devices and aren’t using these alerts and are interested in experiencing the added protection, ask your doctor about them at your next appointment. 

IMPORTANT SAFETY INFORMATION
- Medtronic Diabetes insulin infusion pumps, continuous glucose monitoring systems and associated components are limited to sale by or on the order of a physician and should only be used under the direction of a healthcare professional familiar with the risks associated with the use of these systems. 
- Successful operation of the insulin infusion pumps and/or continuous glucose monitoring systems requires adequate vision and hearing to recognize alerts and alarms. 

Medtronic Diabetes Insulin Infusion Pumps
- Insulin pump therapy is not recommended for individuals who are unable or unwilling to perform a minimum of four blood glucose tests per day. 
- Insulin pumps use rapid-acting insulin. If your insulin delivery is interrupted for any reason, you must be prepared to replace the missed insulin immediately. 

Medtronic Diabetes Continuous Glucose Monitoring (CGM) Systems
- The information provided by CGM systems is intended to supplement, not replace, blood glucose information obtained using a home glucose meter. A confirmatory fingerstick is required prior to treatment. 
- Insertion of a glucose sensor may cause bleeding or irritation at the insertion site. Consult a physician immediately if you experience significant pain or if you suspect that the site is infected.

Hi, I'm waiting for the "new" CGM that is already approved in Europe and it's been promised to be released here in the US early 2012 (yes, 2012!!). Any information related to the timing of that would be great.

Hi, My son currently has a mini-med insulin pump. He has had it for a few years, how do I go about getting him the larger insulin pump? The other question is, what do you typically need to do to get a CGM?

Thank You!

Hi,

I would like to get more information on how to get one of these on Medicare. Thank you.

I would like to know if a prescription is needed for this, how much it costs, does insurance pay for any of it? I have the medtronic revel pump now and it is approx. 2 years old. I would like to have the monitoring system.

My endocrinologist says I need to be on a CGM because of my lack of awareness. I can test and be shocked to see a 28 or a 328. She knows an awful lot, my endocrinologist. However, she has no clue how I'm going to pay for even part of a CGM system on Social Security.

I have been diagnosed with diabetes for over twenty years and pumping for eight years. Twice I have used a CGM and benefited from the results each time. The discounted CGM from Medtronics is a great step forwards, making the CGM itself affordable, but I cannot understand why the consumables are; 1, are so expensive, 2. why they have such a limited 'Use by' date and, 3. why can't they be recognised and added to the (Australian) Pharmaceutical Benefits Scheme.

Hi Joy, we have a team of people here who would love to help you with submitting to your insurance. Over the years, we’ve worked to ensure access to continuous glucose monitoring. Today, we estimate that nearly 90 percent of people with type 1 diabetes with commercial insurance have access to Personal CGM when medical criteria is met. We work with more than 600 insurers nationwide and can often help with the process and paperwork. We also offer financial assistance for those who qualify. I already have your email address so I’ll have a member from my team follow up with you about your options.

Lenea, the Paradigm Revel system, which is the product Kristin is talking about in this post, is an insulin pump with built-in continuous glucose monitoring (CGM). You can learn more about insulin pump therapy and CGM here: http://www.medtronicdiabetes.com/treatmentoptions. If you’d like to talk to someone, you can email me at loopblog@medtronic.com.

Bonita, at this time Medicare does not cover CGM for most patients. Medtronic is actively working with the Centers for Medicare & Medicaid Services (CMS) to ultimately establish coverage consistent with other healthcare insurance companies in the US. Our goal is to ensure consistent access for CGM and insulin pump therapy for all who can benefit. The first step is to work with CMS to assign CGM to a benefit category. We are excited to work this through with industry partners and will keep you updated. We do offer financial assistance to those who qualify, which you can learn more about here www.medtronicdiabetes.com/billing. Please let me know if you have any other questions or if you would like to be connected with a team member to learn about your options.

My Diabetes Educator made an interesting statement during a recent consultation that I am testing. 'Insulin loses it's potency after being exposed to heat after three days'. Three days of insulin equates to approximately 150 units so I am now only filling the reservoirs half way. The results have been very good if you believe glucometer averages. Mine is showing an average of 5.5 over 14 days and has been that way since that meeting. Has anybody else heard of and tried this? and if so, did it make any difference to you? I have purchased a CGM (thanks to the vastly reduced price of $375.00) but I an concerned about the ongoing price ($75.00 per sensor) and how often I should use it. Does anyone have experience of the frequency the CGM should be used?

Phil, we recommend changing your insulin, reservoir and infusion set every 2-3 days and are glad to hear you and your diabetes educator have found the best way to do this with the amount of insulin that you use. I’m sorry to hear about your concern about the cost of sensors, but we are committed to working with our customers to determine the best options for access to our therapies ongoing, whether it be payment plans or insurance coverage support. Studies have shown that the more often sensors are worn, the better the clinical outcomes, with the best results occurring when people wear sensors all the time. We suggest speaking with your healthcare provider to determine the best frequency of use for your individual needs and goals.
