Condition targeted:

Type 1 and 2 diabetes

here is related to type 2 diabetes.

How it works:

  • BlueStar Care Management Portal for population health management, provides the ability to monitor weekly and monthly health trends


Patients using BlueStar typically achieve a 1.7 to 2 points average decrease in HbA1c in the first 3 to 6 months of usage.

What to expect:
