“…Lohan et al reported that 19% of 233 insulin-treated drivers self-reported at least 1 episode of hypoglycemia while driving in the preceding year ( 31 ). The prevalence rate of near-miss accidents related to hypoglycemia and actual traffic accidents was lower than that in our previous study of 133 adults with T1D ( 32 ). Recent advances in diabetes treatment and autonomous driving to avoid accidents may explain this phenomenon.…”

Objective Patients with type 1 diabetes (T1D) and impaired awareness of hypoglycemia (IAH) are at an elevated risk of experiencing automobile accidents. We therefore investigated the association of IAH with driving safety and hypoglycemia problem-solving abilities in adults with T1D. Methods This cross-sectional survey used Gold's method in adult patients with T1D at the National Hospital Organization (NHO) Hospital from February 14, 2020, to October 31, 2021. The participants were divided into control and IAH groups. The data included information on demographics, worries and distress regarding hypoglycemia, hypoglycemia problem-solving abilities, and adverse driving events. Patients We enrolled 233 participants (mean age: 48.5±12.8 years old, mean hemoglobin A1c level: 7.6%±0.9%) from NHO collaborating centers in Japan. Results Among a total of 233 participants (mean age: 48.5±12.8 years old, mean hemoglobin A1c level: 7.6%±0.9%), the prevalence rate of IAH was 11.6% [95% confidence interval (CI): 7.8-16.4%]. IAH was significantly associated with near-miss car accidents (odds ratio: 5.41; 95% CI:1.64-17.80). Diabetic peripheral neuropathy was associated with an increased risk of IAH, while treatment with continuous subcutaneous insulin infusion was not associated with a decreased risk of IAH. The average hypoglycemia problem-solving perception, detection control, and seeking preventive strategies scores in the IAH group were significantly reduced compared with those in the control group. Conclusion IAH was associated with an increased risk of near-miss car accidents among adults with T1D. Furthermore, good hypoglycemia problem-solving abilities were associated with a decreased risk of IAH.
