Introduction: For patients living with T1D, hypoglycemia is the most frequent complication and obstacle in achieving optimal glycemic control with potentially significant adverse implications on individuals’ quality of life. To improve hypoglycemia prevention and management, the BETTER registry for people living with T1D was launched in April 2019 in the province of Quebec, Canada.

Methods: Participants self-register online in the BETTER registry and are asked to answer a series of questionnaires (3 phases). We report the preliminary results of phase I among participants of ≥14 years old, which aims to provide a comprehensive portrait of the population with T1D.

Results: Mid-December 2019, 718 individuals (64.6% female, age 41.8±15.4 years old, duration of diabetes 22.4±14.7 years, 93.2% with T1D and 6.7% with LADA, 71.2% with HbA1c <8%) have registered. Of the participants, 99.6% were currently on insulin therapy (46.7% on insulin pumps, 51.2% on insulin injections, 1.7% using both), and 77.3% were using continuous or flash glucose monitoring. They reported, on average, 6.27±7.42 episodes of hypoglycemia (<54 mg/dl) in the last month. Since their diagnosis, 47.8% of participants had at least one episode of severe hypoglycemia (SH: requiring help from another person or use of glucagon or hospitalization or loss of consciousness). Among those who reported SH in the last 12 months (n=91), the average number of episodes was 2.34±3.37 during this period. When asked what hypoglycemia represents using one word, one-fifth of participants used the word “weak” or “weakness."

Conclusion: In a contemporary group of patients widely using technology for T1D management, hypoglycemia remains frequent. The growing BETTER registry will allow further understanding of this challenging reality and enable future research aiming to reduce hypoglycemia episodes.
