However, there is a growing movement advocating for the adoption of modern techniques like virtual simulators to test AID algorithms.
This shift holds promise for significantly expediting progress in this field.
Unfortunately, there is currently a scarcity of official simulators available.
However, at ATTD2024, prof Peuscher (Ulm University of Applied Sciences, Germany) introduced several open-source diabetes simulators developed by the community (and himself).
These tools, though not exhaustive, are listed below to ensure researchers are aware of these free resources,
which can expedite their investigations and potentially provide quicker access to enhanced AID algorithms.
- Diabetes Type 1 Simulators: Simglucose, LoopInsighT1 (LT1), Closed-Loop Testbed for Resiliende Design and Assessment of APS, Tidepool Simulator
- Diabetes Type 2 Simulators: CarbMetSim, T2DSim, A Type 2 diabetes simulator with web based GUI
- Real-time Simulator: CGMSim
- Personalised Simulation / Digital Twin: ReplayBG, Simulator for T1D with aerobic exercise, Sirael
- Tools: API for the UVA/Padova Type 1 Diabetes Metabolic Simulator, GluPredKit
- Data Analysis: AGATA (Automated Glucose dATa Analysis)
Given the potential for exponential improvement in AID algorithms, especially with the integration of artificial intelligence and additional parameters such as exercise, heart rate, ketones, and lactate, researchers are encouraged to explore these free resources when conducting AID algorithm research.
There is a vibrant community actively working on these open-source diabetes simulators.

10. AID Systems to be Cost-Effective for People with Type 1 Diabetes
As AID systems are becoming the standard of care for those with type 1 diabetes, similar glycemic outcomes are now being observed in individuals with type 2 diabetes.
However, the question remains: will these systems be covered by insurance?
This hinges on lobbying efforts and the willingness of each country to allocate funds.
A publication by Prof Chantal Mathieu and Pieter Gillard describes that although the evidence is still limited, most data indicate that AID systems cost less than the willingness to pay per QALY gained across different countries.
There also give recommendations to ensure that all the benefits of AID systems are thoroughly considered in these analyses.
The hope is that this evidence will establish the cost-effectiveness of AID systems for individuals with all forms of insulin-dependent diabetes, including those with type 2 diabetes who require insulin therapy.
In summary, significant advancements are underway for the available AID systems, with numerous updates on the horizon.
Furthermore, we anticipate the introduction of several new AID systems to the market, which we embrace as greater options can translate to enhanced care.
