Abstract

Aims: We examined severe hospitalised hypoglycaemia (SHH) rates in people with type 1 and type 2 diabetes in Scotland during 2016–2022, stratifying by sociodemographics. Methods: Using the Scottish National diabetes register (SCI-Diabetes), we identified people with type 1 and type 2 diabetes alive anytime during 2016–2022. SHH events were determined through linkage to hospital admission and death registry data. We calculated annual SHH rates overall and by age, sex, and socioeconomic status. Summary estimates of time and stratum effects were obtained by fitting adjusted generalised additive models using R package mgcv. Results: Rates for those under 20 with type 1 diabetes reached their minimum at the 2020–2021 transition, 30% below the study period average. A gradual decline over time also occurred among 20–49-year-olds with type 1 diabetes. Overall, females had 15% higher rates than males with type 2 diabetes (rate ratio 1.15, 95% CI 1.08–1.22). People in the most versus least deprived quintile experienced 2.58 times higher rates (95% CI 2.27–2.93) in type 1 diabetes and 2.33 times higher (95% CI 2.08–2.62) in type 2 diabetes. Conclusions: Despite advances in care, SHH remains a significant problem in diabetes. Future efforts must address the large socioeconomic disparities in SHH risks.

Bibliographical note

We are thankful for the contributions of people with diabetes, National Health Service staff, and organisations (the Scottish Care Information-Diabetes Development Team and Steering Group, the Scottish Diabetes Group, the Scottish Diabetes Survey Group, and the diabetes managed clinical networks) involved in providing data and setting up, maintaining, and overseeing collation of data for people with diabetes in Scotland. Data linkage was performed by colleagues at Public Health Scotland.
