The study examined time trends in severe hypoglycemia among older adults with type 2 diabetes mellitus and antidiabetic treatment. The overall risk of severe hypoglycemia decreased, but patients over 85 years old still had higher rates compared to younger age groups.
Objectives: Hypoglycemia is a potentially life-threatening drug event under antidiabetic treatment. The aim of the study was to examine time trends in severe hypoglycemia in older adults with type 2 diabetes mellitus (T2DM) and antidiabetic treatment. Design: Multicenter prospective diabetes patient follow-up registry (DPV). Setting and Participants: Patients aged >75 years with T2DM and documented treatment between 2005 and 2019. Methods: Outcomes of interest were rates of severe hypoglycemia, diabetes therapy, body mass index, HbA1c, and estimated glomerular filtration rate. Time trends of outcomes were analyzed in the whole cohort and compared between age groups (75-<80, 80-<85, >85 years). Results: A total of 136,931 patients from 188 diabetes centers were included. The adjusted HbA1c decreased from 7.3% (95% confidence interval 7.3-7.4) in 2005 to 7.2% (7.2-7.2) in 2019 (P < .001), with no significant difference between age groups (P = .47). Rates of severe hypoglycemia decreased from 6.7 (6.0-7.4) to 4.1 of 100 person-years (3.7-4.5) (P <.001) in the entire population. Patients aged >85 years had constantly lower HbA1c levels compared with younger groups (P < .001). Although severe hypo-glycemia decreased the most in the >85 age group (P < .001), severe hypoglycemia remained consis-tently higher in this group compared with the 75 to <80 years group (P < .001). Conclusions and Implications: During the analyzed time, the risk for severe hypoglycemia decreased. Although drugs with intrinsic risk for hypoglycemia were used less frequently, antidiabetic treatment in older adults should be further improved to continue reducing severe hypoglycemia in this age group, potentially accepting less strict metabolic control and age-specific target ranges.
