What is the primary benefit of pump therapy in determining the total daily insulin requirement?
What is the primary benefit of pump therapy in determining the total daily insulin requirement?
- It involves establishing the correct basal rate and determining the total basal amount (correct)
- It reduces the need for frequent blood glucose monitoring
- It allows for more insulin to be administered at once
- It eliminates the need for bolus insulin administration

Study Notes
Determining Total Daily Insulin Requirement
- Pump therapy requires less insulin per kilogram than MDI, typically 0.6 to 0.7 units/kg/day for adults.
- An average 70-kilogram adult would require 42 units of insulin per day.
- The total basal requirement is calculated, considering dawn phenomenon or increased insulin resistance in the early morning hours.
Insulin Pump Therapy
- Insulin pumps are wearable devices that connect to narrow, flexible plastic tubing and were FDA-approved in 1983.
- Pumps allow users to deliver a steady trickle or basal amount of insulin continuously throughout the day, providing on-demand insulin for meals and correcting high blood sugars.
Benefits of Insulin Pump Therapy
- Avoidance of severe hypoglycemia
- Improved blood glucose levels and HbA1c outcomes
- Improved lifestyle and greater flexibility
- Improved diabetic ketoacidosis (DKA)
Study Findings
- A 28% reduction in postprandial blood glucose levels with insulin pump therapy compared to Lantus insulin
- Insulin pump therapy reduces HbA1c levels compared to injection therapy in both adults and children
- A 35% reduction in risk of microvascular complications for every percentage point drop in HbA1c levels
- A mean discounted Quality Adjusted Life Year (QALY) gain ranging from 0.70 in adults to 4.27 in adolescents with type 1 diabetes
Challenges and Strategies
- Determining correct basal rates can be challenging due to frequent adjustments or lack of structure in food intake or meal times
- Basal rates may be based on fasting studies or observing blood glucose levels throughout the morning or afternoon
- Increasing the nighttime basal rate can significantly improve fasting glycemic control, reduce hypoglycemic episodes, and not increase hypoglycemia overnight
