Insulin Pumps and Continuous Glucose Monitoring Systems

This CE course for Registered Nurses (RNs) on Insulin Pumps and Continuous Glucose Monitoring (CGM) Systems offers a deep dive into the evolving landscape of diabetes technology. With diabetes affecting millions globally and requiring complex, lifelong management, nurses are on the front lines of educating, monitoring, and supporting patients. This course is specifically designed to provide nurses with the essential knowledge and clinical competencies to optimize care for patients using insulin pumps and CGM systems.

The course begins with a foundational review of glucose metabolism and insulin physiology. Nurses will learn the distinct roles of basal and bolus insulin in maintaining glycemic balance and how these are replicated using multiple daily injections (MDI) and insulin pump therapy. A clear understanding of these concepts is critical to appreciating the advantages of insulin pumps, including their ability to deliver precise insulin dosages, adjust basal rates in real-time, and reduce the risks of hypoglycemia and hyperglycemia when used appropriately.

Participants will explore the components and functionalities of insulin pumps, including bolus calculators, infusion sets, and programmable basal rate settings. Through case studies and simulations, nurses will learn how to determine and adjust insulin-to-carbohydrate ratios (ICRs), insulin sensitivity factors (ISFs), and total daily insulin requirements. Additionally, the course delves into common technical issues and safety concerns such as infusion site problems, diabetic ketoacidosis (DKA) risk, and the importance of consistent blood glucose monitoring.

CGM systems are also covered extensively, with an emphasis on how real-time glucose data enhances patient engagement, facilitates early detection of glucose excursions, and supports proactive therapeutic adjustments. Participants will compare different CGM models, understand calibration needs, and learn how to interpret CGM trend graphs and alerts. The integration of CGM with insulin pump therapy—often referred to as sensor-augmented pump therapy—is also explored as a strategy to achieve optimal glycemic control.

This course includes guidance on patient selection for advanced diabetes technologies, covering psychosocial readiness, manual dexterity, cost and insurance considerations, and the importance of ongoing education and support. Nurses will gain confidence in counseling patients transitioning from MDI to insulin pump therapy, and from traditional blood glucose monitoring to CGM systems. Emphasis is placed on interdisciplinary collaboration, including coordinating care with endocrinologists, diabetes educators, and primary care providers.

By the end of the course, participants will possess the knowledge and skills to support individualized care plans, enhance patient adherence, and improve clinical outcomes in diverse populations. Whether in outpatient settings, acute care, home health, or school health programs, this training empowers nurses to become leaders in modern diabetes management through the effective use of insulin pumps and CGM technologies.

Educational Objectives

After completing this activity, learners will be able to:

• Describe the physiological roles of basal and bolus insulin in glucose regulation and how they are mimicked in diabetes management through MDI and insulin pump therapy.
• Identify the benefits and challenges of insulin pump therapy, including precision in insulin delivery, adjustable basal rates, and potential barriers like cost, skin irritation, and DKA risk.
• Explain the process of determining and adjusting basal rates, insulin sensitivity factors (ISF), and insulin-to-carbohydrate ratios (ICR) to optimize glycemic control.
• Analyze the use of pump bolus calculators and data management tools to enhance diabetes management, reduce glycemic variability, and improve adherence to target ranges.
• Evaluate patient selection criteria for insulin pump therapy and effectively counsel patients on transitioning from MDI to pump therapy, including CGM integration for improved outcomes.

Who Should Do This Course

This course is specifically designed for Registered Nurses (RNs) and Nurse Practitioners working in the fields of Endocrinology, Primary Care, Family Practice, Geriatrics, Pediatrics, and Home Health. It is particularly beneficial for Endocrinology Nurses, Critical Care Nurses, Community Nurses, and Medical-Surgical Nurses seeking to enhance their expertise in advanced diabetes management technologies.

Did You Know?

• According to the CDC, over 37 million Americans have diabetes, with approximately 1.9 million using insulin therapy (CDC, 2022).
• Studies show that patients using CGM systems have a 0.5% to 1.0% reduction in HbA1c levels compared to traditional monitoring methods (Beck et al., 2017).
• Insulin pump users have demonstrated higher satisfaction and improved quality of life compared to MDI users in clinical trials (Pickup et al., 2014).
• The integration of CGM with insulin pumps, known as sensor-augmented pump therapy, can significantly reduce the time spent in hypoglycemia (Tamborlane et al., 2008).
• Proper training and support can reduce insulin pump-related complications by more than 30% (Barnard et al., 2015).
