What Happens to Your Insulin Pump and CGM When You’re Hospitalized?
Whether you’re preparing for a planned procedure or unexpectedly admitted to the hospital, many people with diabetes have the same question: What happens to my insulin pump or continuous glucose monitor when I’m hospitalized?
That question recently came up during an insulin pump training with a patient preparing for an inpatient procedure. It was an excellent question, and one that made me realize how much has changed since I last practiced in the hospital setting. Diabetes technology has advanced rapidly, and hospitals are working to balance the benefits of insulin pumps and CGMs with patient safety, staffing, and evolving clinical guidelines.
Around the same time, I came across an excellent review summarizing the current state of diabetes technology in acute care. It provided a timely overview of where we are today and where inpatient diabetes management is headed.
So, let’s review the latest evidence on using continuous glucose monitors (CGMs) and automated insulin delivery (AID) systems during hospitalization and what patients and healthcare professionals should know before a planned or unexpected hospital stay.
Why Inpatient Diabetes Technology Matters
As CGM and AID use continues to grow, hospitals are seeing these technologies at the bedside more than ever before. Since nearly one in four hospitalized adults has diabetes, effective inpatient diabetes management is critical. Both high and low blood glucose levels during hospitalization are linked to longer hospital stays, more complications, and higher healthcare costs.
Growing evidence suggests that allowing patients to continue using their personal diabetes technology in the hospital can improve glucose management, enhance their experience, and even reduce the workload for healthcare teams.
Therefore, understanding when these devices can be safely continued and when they should be temporarily discontinued is essential for safe inpatient care.
Continuous Glucose Monitoring Is Moving Into the Mainstream
Although no CGM is currently FDA-approved specifically for hospital use, professional societies recommend that many patients who already use CGM can safely continue wearing their device during hospitalization when appropriate protocols are in place.
Recent studies show that CGM can improve Time in Range and enable earlier detection of hyperglycemia and hypoglycemia compared with point-of-care glucose testing alone.
However, confirmatory point-of-care glucose testing may still be needed before treatment decisions, particularly when:
- CGM readings do not match the clinical presentation
- Glucose levels are changing rapidly
- Sensor accuracy is in question
As evidence continues to grow, CGM is becoming an increasingly valuable tool for supporting safe, high-quality diabetes care in the hospital.
For Many, Personal Insulin Pumps Are Staying On
Patients who are clinically stable, alert, and able to safely manage their devices may be appropriate candidates to continue using their personal insulin pump during hospitalization.
The 2026 American Diabetes Association Standards of Care recommend continuing personal insulin pumps during hospitalization when clinically appropriate and when patients are willing and able to self-manage their devices.
Keep in mind that not all insulin pumps function the same way.
Traditional insulin pumps deliver insulin based on programmed settings and may be appropriate to continue in some situations. In contrast, automated insulin delivery systems use CGM data and an algorithm to continuously adjust insulin delivery.
During acute illness or hospitalization, AID may need to be discontinued or transitioned to manual mode if automated insulin delivery is no longer appropriate or is unable to achieve glycemic targets.
Your Hospital Experience May Depend on Where You’re Admitted
One thing is clear: your experience may depend largely on where you are hospitalized, something worth considering when preparing for a planned procedure.
Continuation of CGM and AID systems depends largely on the hospital having appropriate resources, trained staff, competency assessments, and institutional diabetes technology protocols in place.
Hospitals need clear processes for validating device accuracy, documenting CGM and AID data, defining when confirmatory point-of-care glucose testing is required, and determining who is responsible for oversight.
The Future of Diabetes Technology in the Hospital
Diabetes technology is quickly becoming part of routine inpatient diabetes care. As more patients arrive using CGM, insulin pumps, and automated insulin delivery systems, hospitals need clear protocols, trained staff, and reliable workflows to support their safe use.
For patients, whether personal diabetes devices can stay on may still depend on where they are hospitalized. The technology is here. Now, hospital policies and clinical workflows need to keep pace.
Ready to Strengthen Diabetes Care and Education in Your Practice?
Are you looking to build, refine, or expand diabetes care and education services within your practice? I provide flexible, consultative support designed to meet the needs of busy clinics and healthcare organizations.
Diabetes care and education is central to my work. My approach focuses on translating current evidence and standards of care into clear, practical strategies that support sustainable behavior change and informed decision-making.
Let me help you develop patient-centered diabetes care and education that integrates seamlessly into clinical care. Book a discovery call to explore how we might work together.
Often, yes. The ADA recommends continuing personal insulin pumps, including AID systems, when clinically appropriate and when you are willing and able to manage your device. Hospital policies, trained staff, and available resources also matter.
In many cases, yes. Personal CGM may be continued when clinically appropriate, although the hospital may still use fingerstick or point-of-care glucose testing to confirm readings and make treatment decisions.
Possibly. AID systems may be continued when clinically appropriate, but hospital policies and staff experience with diabetes technology vary. The care team may also need to verify your CGM readings and review your pump settings.
Your device may need to be temporarily discontinued if your medical condition makes it unsafe for you to manage it or if the hospital cannot appropriately support its use. Whether a device can stay on should be evaluated based on your individual situation.
Probably. Current ADA guidance recommends confirmatory point-of-care glucose testing for insulin-dosing decisions and hypoglycemia assessment when personal CGM is used in the hospital.
