Embracing Open-Source Automated Insulin Delivery Systems: Understanding Loop and Its Impact on Healthcare
- Jun 10, 2025
- 3 min read
Open-source automated insulin delivery (AID) systems like Loop are no longer on the fringe of diabetes technology. They are embraced by a growing number of individuals with Type 1 diabetes and acknowledged by major medical organizations. These systems are recognized as safe, effective, and deserving of clinical support. Once considered “DIY,” open-source systems are now legitimate care options that healthcare professionals need to understand and promote. Here’s how leading medical organizations are responding to this shift.
American Diabetes Association (ADA)
The 2025 ADA Standards of Care explicitly recommend healthcare provider involvement in supporting open-source AID systems. This marks a pivotal change: the ADA now encourages clinicians to understand how Loop works and to assist patients in using it safely and effectively.
Key Takeaways:
Clinicians should be trained in the fundamentals of open-source AID.
Support should include setup guidance, data review, and optimization.
The ADA emphasizes health equity, noting Loop can offer solutions for patients who can't access commercial AID due to insurance or age restrictions.
By placing Loop alongside commercial AID systems, the ADA has clarified an important stance: if it improves outcomes, providers should be involved.
Diabetes Canada
In 2023, Diabetes Canada stated that healthcare professionals have an ethical duty to support Loop and other open-source systems, especially if they already back commercial AID options. Their position paper highlighted several important points.
Highlights:
Informed Discussions: All effective AID options should be presented to patients, regardless of regulatory status.
Referral Encouraged: If a provider lacks experience with Loop, they should refer to a clinician or peer expert who does.
Use of Nightscout and Tidepool: These tools enable clinicians to review insulin delivery and CGM data for Loop users just like they would with commercial systems.
Diabetes Canada’s message is clear: support for patients should follow their choices, not just what’s FDA-approved.
International Society for Pediatric and Adolescent Diabetes (ISPAD)
The 2024 ISPAD Clinical Practice Guidelines give significant support to open-source AID, particularly for youth. Providers experienced with pumps and CGMs are encouraged to assist families using Loop, even though it's unregulated.
ISPAD Encouragements:
Hands-on Clinical Support: Providers should assist with setup, optimization, and troubleshooting.
Respect for Patient Autonomy: It's vital to respect families' decisions to choose Loop to improve control.
Awareness of Local Regulations: While understanding rules is important, the priority should be on ethical, patient-centered care.
For pediatricians and diabetes educators, ISPAD's endorsement emphasizes the importance of not ignoring open-source tools because they are community-driven.
International Consensus Statement
In 2021, a group of 44 healthcare professionals and legal experts from over 20 countries published a consensus statement in The Lancet Diabetes & Endocrinology, offering ethical and practical guidance on supporting Loop users. Their recommendations include:
Important Recommendations:
Shared Decision-Making: Loop should be introduced as a valid option, especially when commercial AID is inaccessible.
Professional Education: Providers should familiarize themselves with how Loop works or refer to someone who does.
Legal Awareness: Withholding support from a patient using Loop may be unethical; it is essential to document informed conversations and risks.
Clinical Oversight: Utilizing tools like Nightscout, LoopDocs, and OpenAPS documentation helps providers understand algorithm behavior and data interpretation.
This document firmly places Loop support within the providers' responsibilities, especially when it can improve patient outcomes.
EASD and ISPAD Joint Guidance on AID and Exercise
In 2023, a joint position statement by the European Association for the Study of Diabetes (EASD) and ISPAD included Loop in its guidance for AID, particularly during exercise. Clinicians are urged to support patients using any AID system, including open-source ones, during physical activity.
Recommendations Include:
Understanding how Loop's algorithm adjusts insulin during activity.
Helping users configure temporary targets and safe settings for exercise.
Supporting data sharing via Nightscout or Tidepool for post-activity pattern review.
This shows that support for Loop extends into specific contexts, such as sports and exercise.
What This Means for Healthcare Providers
Medical societies globally agree: supporting open-source AID is no longer optional. Healthcare professionals should:
Learn how Loop works using community documentation like LoopDocs.
Review patient data through Nightscout or Tidepool to provide optimization feedback.
Refer when needed to experienced peers or Loop coaches for onboarding and technical assistance.
Treat Loop as a valid, evidence-based tool that enhances glycemic outcomes and quality of life.
More importantly, don't let regulatory hesitation prevent better care. If a patient chooses Loop and it is effective, providers should step in and support.
Conclusion
From the ADA to ISPAD to Diabetes Canada, the unified message is clear: if patients are using Loop, or other open-source automated insulin delivery systems, providers should support them. Open-source AID is safe, effective, and often the most accessible option for individuals living with Type 1 diabetes.
By becoming informed allies, healthcare providers can assist those with Type 1 diabetes in unlocking the full potential of data-driven, automated insulin delivery and remote patient monitoring.
