Summary

The Tempo system enhances management with multiple daily injections because it tracks data in real-time and offers personalized dosing recommendations. This system combines the Dexcom G6/G7 CGM with smart insulin pens for more time in range. 

Loop is a DIY (do-it-yourself) system. It takes some work to set up but allows people to think about diabetes less by automating basal insulin delivery based on predicted glucose levels. This system can be used with the Dexcom G6 and the Omnipod or Medtronic pumps. Information about DIY Loop can be found on the Loop or Riley Link websites.

Device Details

Overview

Discreet and modern option for people using multiple daily injections.

This is a DIY (do-it-yourself) system that needs significant setup. It has the most flexibility in settings and device options. It also depends on a third device called a "Riley Link" to communicate between sensor, phone, and pump. 

Affordability and Access

$$$$
Supplies can be covered for Omnipod or Medtronic pumps and Dexcom. Price range; $0-$8,574 to start and 0-$300/month. iPhone, app, and Riley link are not covered and must be set up independently. Riley link price range; $135-$165.

Patient Considerations

Active Lifestyle

Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.

Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity. *Medtronic option is not waterproof. Omnipod option is fully waterproof. 

Avoiding Highs and Lows

Limited customizability. System integrates the Dexcom G6/G7 CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. 

Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.

Comfort

Many components. Have to carry pens and pen needles. CGM is attached to the body.

Low-profile but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.

Easy Insulin Dosing

Dosing recommendations. Displays personalized mealtime dosing recommendations.

All settings are completely customizable. Can bolus from phone or smartwatch. Can operate “open-loop” where the user must enact insulin delivery based on recommendations or “closed-loop” where modifications to insulin delivery are automatically delivered.

Easy to Use

Simple design. Replaces regular insulin pen. No additional devices to add on. 

Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up. 

Fewer Fingersticks

Factory-calibrated sensor. Finger sticks needed for backup only. 

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone. 

Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available. *Medtronic pump has tubing. Omnipod is most hideable pump option (no tubes or separate controller needed).
