- Abstract
- Background and Aims Hypoglycemia is one of the most important adverse events in individuals with type 2 diabetes mellitus (T2DM). However, hypoglycemia-related events are usually overlooked and have been documented less in clinical practice. Materials and Methods We evaluated the incidence, clinical characteristics, and medical expenses of hypoglycemia related events in T2DM patients based on the Korea National Diabetes Program (KNDP), which is the largest multi-center, prospective cohort in Korea (n = 4,350). For accurate outcomes, the KNDP data were merged with claims data from the Health Insurance Review and Assessment Service (HIRA) of Korea. Results During a median follow-up period of 3.23 years (95% CI: 3.14, 3.19), 88 subjects (2.02%) were newly diagnosed with hypoglycemia, and the incidence of hypoglycemia was 6.44 cases per 1,000 person-years (PY). Individuals with hypoglycemia were significantly older (59.7 +/- 10.7 vs. 53.3 +/- 10.4 years, p < 0.001), had more hospital visits (121.94 +/- 126.88 days/PY, p < 0.001), had a longer hospital stays (16.13 +/- 29.21 days/PY, p < 0.001), and incurred greater medical costs ($ 2,447.56 +/- 4,056.38 vs. $ 1,336.37 +/- 3,403.39 /PY, p < 0.001) than subjects without hypoglycemia. Conclusion Hypoglycemia-related events were infrequently identified among the medical records of T2DM subjects. However, they were associated significantly with poor clinical outcomes, and thus, hypoglycemia could have a substantial burden on the Korean national healthcare system.
