Randomized controlled pilot trial of a hand-held patient-oriented, insulin regimen optimizer

Area of Science:

• Medical Devices
• Diabetes Technology
• Artificial Intelligence in Healthcare

Background:

• Type 1 diabetes management requires continuous glucose monitoring and optimized insulin dosing.
• Traditional insulin regimens can be challenging for patients to manage effectively.
• Decision support systems can potentially improve glycemic control and patient outcomes.

Purpose of the Study:

• To develop and evaluate a patient-oriented insulin regimen optimizer (POIRO) for type 1 diabetes management.
• To assess the impact of POIRO's decision support on glycemic control.
• To determine patient acceptance and potential educational value of the device.

Main Methods:

• Development of a hand-held, touch-screen device (POIRO) integrating a hybrid expert system for insulin dose suggestions.
• Formal evaluation in a randomized crossover pilot trial with six type 1 diabetes patients.
• Comparison of glycemic control over two 3-week periods: with and without POIRO decision support.

Main Results:

• Significantly lower mean pre-prandial blood glucose levels when using POIRO decision support (7.5 mmol/l vs. 8.9 mmol/l).
• No increase in the frequency or severity of hypoglycemia during the decision support period.
• Positive patient reception and indication of potential educational value and persistent improved control.

Conclusions:

• The POIRO device effectively improves glycemic control in type 1 diabetes patients.
• It offers a potentially inexpensive, remote method for providing expert diabetic advice.
• The device may have educational value and can be used intermittently for sustained benefits.
