Persistent Burden of Severe Hypoglycemia and Impaired Awareness of Hypoglycemia Among People With Type 1 Diabetes Despite Technology Use: A Follow-up Survey
Authors' conclusion
Although most participants used CGM and the use of AID increased, approximately one-third of respondents did not achieve HbA1c targets, ∼20% continued to have SHEs in the last year, and ∼30% had IAH. This highlights that while CGM and AID systems are a significant advancement, their use alone has not mitigated the risk of severe hypoglycemia, and glucose management still remains suboptimal.
