Time in Range | American Diabetes Association

The American Diabetes Association (ADA) wants to help you understand time in range (TIR) as a new blood glucose management measure and implement it with the appropriate patients today.


For many people with diabetes, blood glucose monitoring is key for achieving glycemic targets. Self-monitoring of blood glucose is an integral component of effective therapy of patients taking insulin. In recent years, continuous glucose monitoring (CGM) has emerged as a complementary method for assessing blood glucose levels. CGM accuracy and affordability has evolved rapidly and many patients have these data available to assist with both self-management and assessment by providers. Reports can be generated from CGM that will allow the provider to assess hypoglycemia, hyperglycemia, and glycemic variability plus determine TIR. 

A consensus document highlighted the type of report that can be generated (1). (See Fig. 6.1 from the ADA’s Standards of Medical Care in Diabetes shown above). Published data suggest a strong correlation between TIR and A1C, with a goal of 70% TIR aligning with an A1C of ∼7% in two prospective studies (2, 3).

The ADA’s Time in Range initiative will provide guidance on treating your patients with diabetes who might benefit from time in range. Visit the Institute of Learning for TIR webinars, podcast episodes, and practice pearl videos.

2023 ADA Standards of Care: Diabetes Technology Update

March 1, 2023 at 4 pm ET

The Standards of Care in Diabetes (SOC) includes all of ADA’s current clinical practice recommendations and is intended to provide clinicians, patients, researchers, payers, and others with the components of diabetes care, general treatment goals, and tools to evaluate the quality of care. The recommendations are based on an extensive review of the clinical diabetes literature, supplemented with input from ADA staff and the medical community at large. ​This webinar will discuss the latest guidelines that pertain to diabetes technology/ TIR and address how the 2023 recommendations can be implemented in clinic.​

Time in Range: Reducing Barriers 

September 27, 2022 at 4 pm ET

Join Dr. Monica Peek and Dr. Anne Peters as they discuss the barriers that prevent or delay healthcare professionals from utilizing diabetes technology and CGM metrics, such as time in range, to treat patients. They will review the use of various diabetes technologies to achieve time in range and provide insight on how they overcame barriers within their practice that serves diverse populations.   ​
