We quizzed test takers on the new ADA 2022 Standards of Care for CGMs. 71% of respondents chose the best answer. We want to share this important updated information, so you can pass it on to people living with diabetes and your colleagues, plus prepare for exam success!
Before we start though, if you don’t want any spoilers and haven’t tried the question yet, you can answer below: Answer Question
Question: In the 2022 ADA Standards, there are updated indications for use of real-time continuous glucose monitoring or intermittently scanned continuous glucose monitoring. Based on the new guidelines, which one of the following individuals needs to be offered continuous glucose monitoring to manage their diabetes?
Answer Choices:
- AL, a 54-year-old on a sulfonylurea plus metformin.
- RT, a 68-year-old on basal insulin and an SGLT-2 Inhibitor.
- ZR, a 23-year-old with diabetes secondary to HIV retroviral therapy.
- AW, an 18-year-old with prediabetes.

As shown above, the most common choice was option 2, the second most common answer was option 3, then option 1, and then finally option 4.
Getting to the Best Answer
Answer 1 is incorrect. 11.08% chose this answer, “AL, a 54-year-old on a sulfonylurea plus metformin.” This is a juicy answer, since AL is taking a medication that can cause hypoglycemia. This person would benefit from a glucose meter and instruction on the signs of hypoglycemia and what action to take if they have symptoms of low blood sugar. However, according to the standards, continuous glucose monitoring is not indicated for people with type 2 on orals. But knowing that insurance probably won’t cover a CGM, AL could choose to purchase (out of pocket) an intermittently scanning glucose meter to keep a close eye on their blood sugars.
Answer 2 is correct. 71.03%% of you chose this answer, “RT, a 68-year-old on basal insulin and an SGLT-2 Inhibitor.” GREAT JOB! According to the ADA Diabetes Technology Standard 7, “real-time continuous glucose monitoring or intermittently scanned continuous glucose monitoring can be used for diabetes management in adults with diabetes on basal insulin who are capable of using devices safely (either by themselves or with a caregiver). The choice of device should be made based on patient circumstances, desires, and needs.” In addition, this standard outlines that CGM should be offered during pregnancy and for youth and adults who are using insulin therapy to get glucose to target.
Answer 3 is incorrect. 14.42% of respondents chose this answer, “ZR, a 23-year-old with diabetes secondary to HIV retroviral therapy.” This answer is tempting. However, there is no indication in this answer that ZR is on insulin therapy and that is why it is not the best answer. The latest ADA Standards recommends CGM for adults on insulin therapy.
Finally, Answer 4 is incorrect. 3.47% chose this answer, “AW, an 18-year-old with prediabetes.” Good try. Currently, CGM is only recommended for people with diabetes on insulin or during pregnancy. Off the record, people with prediabetes might decide to purchase a blood glucose meter (if their insurance company doesn’t cover it) to keep an eye on their glucose levels and use the results as motivation to make lifestyle changes.
