| Summary: | To determine if impaired awareness of hypoglycemia in patients with type 1 diabetes persists over time and to assess if continuous glucose monitoring use was associated with improved awareness of hypoglycemia in our population.
Thirty-six with type 1 diabetes and impaired awareness of hypoglycemia who participated in studies on impaired awareness of hypoglycemia between 2009 and 2015 were contacted to complete an online survey. The survey included the Cox/Clarke and Gold hypoglycemia questionnaires and questions about continuous glucose monitoring use.
23 of 36 (63%) subjects contacted completed the survey. (12 M, 11 F; median age 51 years, median diabetes duration 34 years). One had had an islet cell transplant and was excluded. Persistent impaired awareness of hypoglycemia was found in 19/22 (86%) using the Cox questionnaire and 18/22 (82%) using the Gold questionnaire. Consistent use of continuous glucose monitoring over the last six months defined as using a device ≥75% of time over the last 6 months was reported by 67% (12/18) and 68% (13/19) of participants with persistent impaired awareness of hypoglycemia as measured by Gold and Cox; respectively. Nineteen of the 22 participants (86%) reported severe hypoglycemia over the last six months.
Impaired awareness of hypoglycemia persisted in >80% of the subjects with type 1 diabetes we studied between 2009 and 2015. While the consistent use of continuous glucose monitoring among our participants was high; it did not translate into restoration of hypoglycemia awareness in this population. This real world data shows that severe hypoglycemia continues to be a frequent problem in this patient population. |
