Insulin pumps for continuous glucose monitoring -

When a stopping criterion is met, e. One limitation of detection-based algorithms is that the attenuation of basal insulin at the time of hypoglycemia detection can only reduce the duration of the hypoglycemic event, but cannot prevent the event from happening, especially because of the intrinsic delay of subcutaneous insulin absorption.

For example, Swan et al. reported that, after a subcutaneous bolus of insulin, the peak of plasma insulin occurred 60 min after the bolus time [ 13 ]. Therefore, even if basal insulin is suspended when hypoglycemia is detected, there is still some previously-injected insulin active in the plasma causing a lowering in BG concentration.

To overcome this limitation, prediction-based attenuation methods can be used. Specifically, in prediction-based methods, CGM measurements and optionally other input data, e. insulin doses, are used to forecast future glucose concentration.

If a hypoglycemia is predicted to occur in the near future, i. Besides the threshold T , another key parameter to tune the performance of prediction-based algorithms is the prediction horizon PH , i. how much time in advance the hypoglycemic event would be predicted.

Ideally, a longer PH would be desirable in order to anticipate the attenuation of basal insulin and thus compensate the delay of insulin action. However, in practice a too long PH is not convenient, because it increases the rate of false positives i.

predicted hypoglycemic events that do not happen in reality , and thus the risk of rebounds in hyperglycemia. Finally, methods are classified as suspension algorithms if, instead of attenuating the basal insulin delivery, they simply interrupt basal insulin delivery when hypoglycemia is detected detection-based suspension methods or predicted prediction-based suspension methods.

Here, we illustrate the approaches developed so far, distinguishing those applying a pump suspension from those applying a modulation of basal insulin delivery. The characteristics of algorithms developed in academia are summarized in Table 1. The first attempt to produce an algorithm to suspend the basal insulin infusion rate based on CGM values is due to the research group of Dr.

Bruce Buckingham. Indeed, in Buckingham and colleagues developed and tested a method to discontinue insulin pump injection when hypoglycemia is predicted from real-time CGM [ 14 ]. In particular, two methods were proposed for glucose prediction: a simple linear prediction algorithm that predicts future glycemia by linear extrapolation of CGM data; and a method using multiple empirical statistical models to estimate probability of future hypoglycemia [ 15 ].

The algorithms were assessed in a daytime 7-h in clinic experiment in which hypoglycemia was induced by controlled increase of basal insulin infusion rate. further developed their method and tested a second prediction-based suspension algorithm for prevention of nocturnal hypoglycemia in clinic [ 16 ].

The 5 prediction algorithms considered were: linear extrapolation, Kalman filtering [ 18 ], adaptive hybrid infinite impulse filter, statistical prediction [ 15 ] and numerical logical algorithm. Instead of using a fixed suspension time of 90 min as in their previous study, the authors proposed a new criterion for early restart of basal insulin in case i at least 30 min passed since suspension started, ii CGM rate of change is more than 0.

Among the 5 prediction algorithms, the only algorithm that did not play a significant role in the generation of hypoglycemia alarms was the linear extrapolation, result that justifies the investigation of more complex prediction algorithms. In their subsequent work, Buckingham and coauthors abandoned the idea of having multiple prediction algorithms in favor of using a single Kalman filter prediction algorithm with a PH of 70 min [ 19 ].

For this purpose, the criteria to restart the basal insulin were also updated. In work by Cameron et al. Moreover, the algorithm allowed a maximum suspension time of min every min and min per night. The new algorithm was tested in clinic in 16 subjects. Nevertheless, the authors stated their study was not designed to rigorously assess the rebound in hyperglycemia, because hypoglycemia was artificially induced by increasing basal insulin delivery, and no control subjects were studied.

In , Buckingham et al. The authors then decided to revise their algorithm to reduce the occurrence of pump suspension. The algorithm by Buckingham et al. The efficacy of the algorithm was first tested in a simulated experiment.

Results suggested that adding accelerometer data allowed to improve the performance of the pump suspension algorithm, while further addition of heart rate monitor data did not significantly improve the performance of the system.

Starting from , the research group led by Prof. Boris Kovatchev at the University of Virginia has been working on a different approach, i. algorithms to attenuate, rather than suspend, the basal insulin delivery according to the risk of hypoglycemia.

The two main approaches that they developed were called Brakes and Power Brakes [ 22 ]. As visible in Fig. Attenuation function used in the Brakes and Power Brakes algorithms. Plot of the attenuation function used in the Brakes and Power Brakes algorithms see Eq.

Power Brakes is a prediction-based algorithm that uses both CGM and insulin data to forecast glucose concentration in the next 15 min and attenuate basal insulin delivery accordingly. Specifically, glucose prediction is performed by the Kalman filter using as underlying model the metabolic state observer, i.

a linearized and discretized version of the subcutaneous oral glucose minimal model [ 24 ] with population parameters. The inputs of the model are CGM measurements and insulin pump delivery rate. The basal insulin attenuation factor is calculated as in Brakes Eq.

the min ahead predicted glucose concentration returned by the Kalman filter. The method of Power Brakes was further developed in work by Hughes et al. The goal was to let the algorithm anticipate routine behavioral events that can cause hypoglycemia, like exercise or consistent over-delivery of insulin.

In the version of Power Brakes enhanced with historical CGM data, the Kalman filter and the metabolic state observer are used in real-time to filter the CGM signal and obtain a clean estimate of current glucose concentration. This is then projected in the next 30 min using a simple linear regression model with patient-specific parameters that depends on the time of the day updated every 30 min and have been estimated from historical CGM data collected in the previous 30 days.

Another variation of the Power Brakes algorithm was proposed by Patek et al. Predicted glucose is then corrected to account for the effect of insulin-on-board IOB , i. previously injected insulin that is still active in the body.

This is done by subtracting to the predicted glucose concentration a term proportional to an estimate of current IOB, obtained using insulin action curves of different duration 4—8 h in different glucose ranges. The glucose value obtained after IOB correction is used to calculate the risk of hypoglycemia using the same function of the original Power Brakes formulation, but with different parameters.

Particularly, in the SSM variant, basal insulin attenuation is triggered only if CGM is lower than Finally, the attenuation factor is calculated as in Eq.

Since the availability of first CGM sensors, insulin pump companies understood the potentiality of exploiting CGM data in real-time to improve insulin infusion and, thus, glucose control.

Commercial devices implementing basal insulin suspension algorithms. Medtronic Inc. Northbridge, CA has been one of the most active companies working at the development of both detection- and prediction-based suspension algorithms.

Indeed, Medtronic Inc. launched in the first system for diabetes management integrating CGM and insulin pump technologies in the same medical device MiniMed Paradigm REAL-time system.

Later on, Medtronic Inc. developed the Medtronic Paradigm Veo Fig. the first device equipped with an automatic detection-based basal insulin suspension feature, which became commercially available outside the U.

in The fixed 4-h re-activation of insulin delivery was introduced to prevent the occurrence of diabetes ketoacidosis. Nevertheless, the patient could manually interrupt the LGS cycle at any time and resume normal basal insulin delivery [ 27 ]. In the U. Among MiniMed G users, the mean low threshold setting was The system automatically suspends basal insulin delivery when glucose concentration is predicted to reach or fall below a preset glucose threshold in the next 30 min and automatically restarts basal insulin on recovery from hypoglycemia [ 29 ].

With the MiniMed G, the percentage of suspension events manually interrupted by the user decreased to Many studies were performed to assess the effectiveness and the safety of basal insulin suspension algorithms both in clinic under controlled conditions [ 14 , 16 , 19 , 31 , 32 , 33 , 34 , 35 ] and at home under real-life conditions [ 20 , 29 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ].

The safety is intended as the ability of the algorithm not to produce rebounds in hyperglycemia and adverse events, like diabetes ketoacidosis, that can result from an extended suspension of basal insulin delivery. Evidences from these trials support the effectiveness of the algorithm in reducing hypoglycemia, at the price of a slight increase in hyperglycemia that, however, was not associated with an increase of HbA1c or the occurrence of ketoacidosis.

Nevertheless, no significant change in HbA1c was observed. Moreover on 14 occasions, there were more than one 2-h suspension per night. These clinical trials also confirmed the evidence reported in Agrawal et al.

An investigational Medtronic device with the PLGM feature was assessed by Abraham et al. in experiments of insulin-induced [ 33 ] and exercise-induced [ 34 ] hypoglycemia and under real-life conditions [ 43 , 45 ], demonstrating the effectiveness of the algorithm in reducing hypoglycemia and hypotreatment requirements.

The commercial MiniMed G system was assessed in a single-arm outpatient study [ 29 ], a single-arm inpatient study with nocturnal hypoglycemia induced by increased insulin delivery [ 35 ], and a randomized controlled trial conducted in children and adolescents [ 42 ]. In study by Choudhary et al.

Basal insulin delivery was manually restarted by the user in In their randomized clinical trial comparing SAP with and without PLGM, Battelino et al. Zhong et al. As far as noncommercial algorithms are concerned, the algorithm based on Kalman filter prediction developed by Buckingham et al.

The algorithm was running in a bedside laptop communicating with the Paradigm Veo pump and the Medtronic Enlite sensor. Results showed that the prediction-based suspension algorithm was effective in reducing hypoglycemia in all age groups.

Despite the higher occurrence of morning hyperglycemia in patients using the suspension algorithm, no significant increase in morning blood ketones and no serious adverse event was observed [ 39 , 46 ].

All the aforementioned clinical trials were performed with either detection-based or prediction-based suspension algorithms. In Hughes et al. In the second scenario, Brakes was able to reduce the duration of hypoglycemic events but did not succeed in preventing any of them.

Hughes et al. Results showed that the addition of historical CGM data allowed to modestly improve the performance of Brakes in preventing hypoglycemia, although an assessment of these techniques in either real clinical studies or more realistic in silico experiments is necessary to better understand the potential benefits of using historical data to enhance pump attenuation algorithms.

However, this shift was compensated when the module of the closed-loop system responsible for recommending both positive and negative basal insulin adjustments Range Correction Module was activated under the supervision of the SSM.

Although the encouraging results obtained in these short in silico experiments, to the best of our knowledge, Brakes and Power Brakes were never assessed as standalone algorithms in clinical trials, but only in closed-loop control trials, where they have been embedded in the SSM, making impossible to distinguish their effectiveness from that of the closed-loop controller.

In addition, the effectiveness and safety of such algorithms have never been tested in more realistic long-duration in silico clinical trials when new and more reliable simulators were released [ 48 , 49 ]. The availability of insulin pumps communicating with CGM sensors has stimulated the development of algorithms for the automatic suspension or attenuation of basal insulin delivery when hypoglycemia is either detected or predicted from CGM readings.

Some algorithms were also implemented in commercial integrated systems produced by Medtronic. The commercially available algorithms are all suspension algorithms, i. they can only turn on or off basal insulin delivery, and rely only on CGM measurements for the prediction of future hypoglycemia [ 27 , 28 , 29 ].

Literature studies have shown that the performance of glucose prediction algorithms can significantly improve when additional inputs are considered apart from CGM, like insulin, meals, and physical activity, all factors that strongly impact glycemic excursions [ 50 , 51 , 52 ].

Some literature studies on basal insulin attenuation algorithms have explored the possibility of enhancing glucose prediction by taking into account insulin data [ 22 , 26 ] and historical CGM data [ 25 ].

However, such algorithms have been tested only in short in silico experiments and a more extensive evaluation is needed to understand the real benefits of using insulin and historical glucose data as additional inputs for glucose prediction.

A first step in this direction could be the assessment of these algorithms using a more advanced simulation framework including a description of physiological, technological and behavioral variability, which allows the simulation of realistic multiple-day scenarios [ 48 , 49 ].

In another literature study, physical activity data were used to enhance the performance of an algorithm for basal insulin suspension in mitigation of exercise-induced hypoglycemia [ 21 ]. However, in the proposed algorithm, physical activity could trigger basal insulin suspension independently on glucose prediction.

A more robust approach would be to use physical activity data to enhance glucose prediction and then use the prediction derived from CGM, physical activity and possibly other input data to trigger basal insulin suspension.

Another interesting idea that has been proposed in the literature is the use of a smoothed attenuation function [ 22 , 25 , 26 ]. Further assessments are needed to understand the real benefits of using a smooth attenuation function instead of a threshold-based suspension strategy, like that implemented in commercial devices.

Indeed, the plot of Fig. The assessment of basal insulin suspension algorithms in clinical trials showed that these methods are effective in reducing hypoglycemia outcomes, except the rate of events of profound hypoglycemia e. The price is a slightly increase of time spent in the high glucose range e.

diabetes ketoacidosis associated with the use of suspension algorithms was observed. As Hughes et al. shown in a simulated case study [ 22 ], the simple attenuation of basal insulin when hypoglycemia is predicted may not be sufficient to prevent episodes of profound hypoglycemia caused by large insulin boluses, unless this is combined with carbohydrate intake.

Therefore, a possible effective solution for the prevention of profound hypoglycemia could be the combination of basal insulin attenuation algorithms with algorithms for the suggestion of preventive hypotreatments in presence of elevated hypoglycemia risk.

Such preventive hypotreatment advisory systems could be also applied to mitigate hypoglycemia in patients on traditional multiple daily injections therapy. To minimize the undesired rebound in the high glucose range following a suspension event, basal insulin attenuation algorithms can be coupled with algorithms allowing automatic basal insulin increase in response to high glucose concentration.

This strategy was supported, for example, by Patek et al. that showed the performance of their SSM increased when this was coupled with the Range Correction Module allowing positive insulin corrections [ 26 ].

In recent work by Spaic et al. Two recent randomized clinical trials showed that the addition of the insulin-dosing component allowed the system to increase time in target and reduce mean morning glycemia, without deteriorating the performance in hypoglycemia mitigation [ 53 , 54 ].

Systems like these that allow real-time automatic positive and negative adjustments of basal insulin delivery are examples of hybrid closed-loop systems, which have been object of intense research activity in the last 10 years and recently entered the market, with the Medtronic MiniMed G being the first commercial hybrid closed-loop system [ 55 , 56 , 57 ].

In conclusion, basal insulin attenuation algorithms are a promising technique for the mitigation of hypoglycemia in SAP therapy and represent the first step towards a fully closed-loop system. Although some of these algorithms have already been implemented in commercial devices, there are still many margins for improving their performance.

Most CGMs send information without using wires to an app on a smartphone. Other differences between CGM models include whether the sensor is placed on the skin or is implanted how often the sensor has to be replaced how long it takes the CGM to warm up how you adjust the program settings For some CGM models, you may need to do a finger-stick test with a standard blood glucose monitor to calibrate the system and make sure the CGM readings are correct.

Many CGMs work with apps that have special features, such as ways to track the food and beverages you consume, your physical activity level, and the medicines you take the ability to download data onto a computer or smart device so you can easily see trends in your glucose levels an alarm that goes off when your glucose level is too low or too high, helping you prevent emergencies For safety, it is important to act quickly if a CGM alarm sounds when your glucose level is too low or too high.

Compared with a standard blood glucose meter, using a CGM can help you better manage your glucose levels every day have fewer low blood glucose emergencies need fewer finger sticks The CGM will create an alert and might display a graphic that shows whether your glucose level is rising or dropping—and how quickly—so you can choose the best way to reach your target range.

The Bolus Delivery plus Display and Data Upload feature set additionally allows users to request, stop, and cancel a bolus on the pump from the t:connect mobile app. An insulin pump is a small, computerized device worn outside of the body that delivers insulin under the skin.

A hybrid closed loop insulin pump attempts to mimic the body's natural communication loop by linking with a secondary device called a continuous glucose monitor, or CGM, sensor and automatically adjusting some of the insulin delivered based on continually monitored blood sugar levels.

The term "hybrid" is used because it is not a full closed loop. Although the system can monitor blood sugars and adjust insulin based on the data, it needs to be adjusted manually when a person eats a meal or if there is a sudden rise in blood sugar.

It has been approved for use by people with Type 1 and Type 2 diabetes. In contrast to this, open loop insulin delivery systems rely on people checking blood sugars frequently often by pricking their finger multiple times daily and using that information to determine how much insulin to take.

Hybrid closed loop insulin pumps are exciting new tools that can significantly improve into the health and wellness of people living with diabetes. Talk with your health care professional about if a hybrid closed loop insulin pump is right for you.

Benefits Research has shown that hybrid closed loop insulin pumps provide many benefits for people living with diabetes, including: Reduced risk of low blood sugars Clinical trials have shown that hybrid closed loop insulin pumps reduce the risk of low blood sugar. When used with a continuous glucose monitor, an insulin pump can turn itself off or adjust the amount of insulin that it's giving the person depending on the trend in the blood sugar.

If the pump starts to notice that blood sugar is trending downward, it'll turn itself off or reduce the insulin. This reduces the risk of having low blood sugar, which can be a detrimental event.

Reduced disease burden One of the reasons why living with diabetes can be tiring is the number of decisions that need to be made each day. How much insulin should you give yourself? How do you modify your insulin based on what you're going to eat?

Will exercising longer affect your blood sugar? Should you inject insulin now or later? An insulin pump is not going to answer all those questions or solve all problems, but it significantly reduces some of the decision-making needed.

By automatically adjusting background or basal insulin for people with diabetes, it can reduce decision fatigue and improve quality of life. It's also useful for people who have an unpredictable activity schedule or work hours, since it releases a constant flow of insulin into the body, preventing the effects on blood sugar that can occur when occasionally forgetting to inject a long-acting insulin shot.

Improved monitoring and response to trends All hybrid closed loop insulin pumps will monitor blood sugar trends over time. Many display the information on a mobile app that can be shared with family, friends and health care professionals.

This information helps make treatment decisions and identify triggers to spikes or drops in blood sugar levels. It also helps from a safety perspective, particularly in children with diabetes.

Parents can receive alarms and intervene if the child's blood sugar is particularly low or high.

Considerations There are a few things to think about when deciding if a hybrid closed loop insulin pump is right for you, such as: Your comfort with technology A sense of comfort with technology and willingness to learn the system is important for success.

The system uses advanced technology, which means user errors or technology failures are possible. People considering this system need to understand what the pump is doing so they can step in and manually adjust insulin if the system isn't working as expected.

Your comfort with adjusting The system is designed to be adjusted and calibrated by the patient over time. People cannot just set it on autopilot and expect it to work perfectly.

People who have reliably checked blood sugar levels and are invested in managing diabetes will have greater success. Tube or tubeless There are two general categories of hybrid closed loop insulin pumps available: those that use insulin tubes and others that are tubeless.

Pumps that use tubing connect the reservoir of insulin to a catheter that's inserted under the skin. Tubeless pumps connect directly under the skin without any tubing to a reservoir. Consider which option may be best for your situation and comfort level.

People who live an active lifestyle, have an active job or are prone to tube damage may benefit more from a tubeless pump.
