Modifiable factors to prevent severe hypoglycaemic and diabetic ketoacidosis presentations in people with type 1 diabetes

Aims In tackling rising diabetes‐related emergencies, the need to understand and address emergency service usage by people with type 1 diabetes is vital. This review aimed to quantify current trends in presentations for type 1 diabetes‐related emergencies and identify public health strategies that reduce the frequency of diabetes‐related emergencies and improve glycaemic management. Methods Medline (OVID), Cochrane and CINAHL were searched for studies published between 2000 and 2023, focusing on people with type 1 diabetes, severe hypoglycaemia and/or diabetic ketoacidosis, and ambulance and/or emergency department usage. There were 1313 papers identified, with 37 publications meeting review criteria. Results The incidence of type 1 diabetes‐related emergencies varied from 2.4 to 14.6% over one year for hypoglycaemic episodes, and between 0.07 and 11.8 events per 100 person‐years for hyperglycaemic episodes. Notably, our findings revealed that ongoing diabetes education and the integration of diabetes technology, such as continuous glucose monitoring and insulin pump therapy, significantly reduced the incidence of these emergencies. However, socio‐economic disparities posed barriers to accessing these technologies, subsequently shifting the cost to emergency healthcare and highlighting the need for governments to consider subsidising these technologies as part of preventative measures. Conclusions Improving access to continuous glucose monitoring and insulin pump therapy, in combination with ongoing diabetes education focusing on symptom recognition and early management, will reduce the incidence of diabetes‐related emergencies. Concurrent research assessing emergency healthcare usage patterns during the implementation of such measures is essential to ensure these are cost‐effective.
