Performance of a Blood Glucose Monitoring System in a Point-of-Care Setting

Area of Science:

• Clinical Chemistry
• Medical Device Technology
• Point-of-Care Testing (POCT)

Background:

• Point-of-care testing (POCT) requires stringent quality control for reliable patient results.
• Hospital settings demand accurate and compliant blood glucose monitoring systems (BGMS).
• International guidelines, including ISO15197:2013, RiliBÄK, and QUALAB, set critical accuracy and quality benchmarks for BGMS.

Purpose of the Study:

• To evaluate the CONTOUR® XT-BGMS (CXT-BGMS) for accuracy and compliance in a hospital POCT setting.
• To assess CXT-BGMS adherence to German (RiliBÄK) and Swiss (QUALAB) quality control guidelines.
• To verify CXT-BGMS performance against ISO15197:2013 accuracy criteria.

Main Methods:

• A single-center study conducted in Switzerland.
• Testing of 105 venous blood samples from hospitalized patients.
• Comparison of CXT-BGMS results against the hexokinase reference method.
• Daily quality control measurements using control solutions to assess POCT guideline compliance.

Main Results:

• CXT-BGMS achieved 98.41% accuracy, meeting ISO15197:2013 criteria.
• All control measurements complied with RiliBÄK guidelines (±11% of target values, within RMSE limits).
• All control measurements complied with QUALAB guidelines (±10% of target values).

Conclusions:

• The CONTOUR® XT-BGMS (CXT-BGMS) demonstrates compliance with German (RiliBÄK) and Swiss (QUALAB) quality control guidelines.
• CXT-BGMS meets the ISO15197:2013 accuracy requirements for blood glucose monitoring systems in hospital POCT settings.
• The study confirms the reliability and accuracy of CXT-BGMS for routine use in clinical practice.
