The Evaluation of Laser Lancing Devices in Adult Type 2 Diabetes Patients

Not Applicable

• Conditions: Type 2 Diabetes
• Interventions: Device: laser lancing device or lancet for blood glucose level measurement

• Registration Number: NCT05251506
• Lead Sponsor: Korea University Guro Hospital

Brief Summary

Self monitoring of blood glucose level is crucial in diabetes management, but currently available methods, lancet, have shown low compliance of self monitoring of blood glucose because of pain, keratinization of finger tip, secondary infection. The purpose of this study is evaluating laser lancing device which cause much less pain than lancet to increase compliance of blood sugar checking, and to establish self monitoring system for patients of chronic diseases.

The investigators recruit total of 80 type 2 diabetes patients who visit Korea University Medical center Guro and Ansan hospital. HbA1c level of subject is more than 6.5% and less than 8.5%, and their age is above 20 years and under 80 years. Subjects are randomly distributed in group A or B. Group A subjects use laser device to check blood glucose for 2 months, then take a month for wash out period. After wash out period, participants use lancet for following 2 months. Group B perform the process vice versa. The investigators evaluate the number of blood glucose measurement, HbA1c, diabetes distress scale, average pain score, average satisfaction score from each group.

Detailed Description

Self monitoring of blood glucose level is crucial in diabetes management, so it is important to increase compliance of blood glucose checking. Lancet which is currently available methods have shown low compliance of self monitoring of blood glucose, since it causes pain, keratinization of finger tip, secondary infection. The purpose of this study is evaluating laser lancing device which cause much less pain than lancet to increase compliance of blood sugar checking, and to establish self monitoring system for patients of chronic diseases.

The investigators recruit total of 80 subjects who visit Korea University Medical center Guro and Ansan hospital. Study subject are type 2 diabetes whose glycated hemoglobin level is more than 6.5% and less than 8.5%, and whose age is more than 20 years and under 80 years. Subjects are randomly distributed in group A or B. Group A subjects use laser device to check blood glucose for 2 months, then take a month for wash out period. After wash out period, participants use lancet for following 2 months. Group B subjects use lancet first, then have a month for wash out period, after then, switch to laser device afterwards. During washout period, participants use usual glucose checking method which subjects had used. The investigators evaluate the number of blood glucose measurement, glycated hemoglobin, diabetes distress scale, average pain score, average satisfaction score from each group. Also the investigators compare blood glucose, liver function test, lipid level between values from one hand measured by lancet, and values from the other hand measured by laser lancing device.
