Understanding Mortality in Diabetes: Causes and Care Approaches
Diabetes Mortality Statistics
Diabetes is a significant global health issue, contributing to a substantial number of deaths annually. In 2019, diabetes was responsible for an estimated 4.2 million deaths among adults aged 20-79 years, accounting for 11.3% of global deaths in this age group. The prevalence of diabetes-related deaths varies by region, with the highest proportion in the Middle East and North Africa (16.2%) and the lowest in Africa (6.8%). Notably, nearly half of these deaths occur in individuals under the age of 60, highlighting the severe impact of diabetes on younger populations.
Primary Causes of Death in Diabetic Patients
While diabetes itself is a chronic condition, the primary causes of death in diabetic patients are often related to its complications rather than acute metabolic emergencies. Cardiovascular disease, chronic kidney disease, dementia, respiratory diseases, and cancer are the leading causes of death among individuals with diabetes . Acute complications such as diabetic ketoacidosis (DKA), hyperosmolar hyperglycaemic state (HHS), and hypoglycemia are less commonly the direct cause of death .
Regional Disparities and Access to Care
Access to insulin and comprehensive diabetes care significantly influences mortality rates. In sub-Saharan Africa, lack of access to insulin is a major cause of death among children with diabetes. Conversely, in regions like South India, robust support systems and comprehensive care programs have significantly improved outcomes for children and adolescents with type 1 diabetes, allowing many to lead healthy lives into adulthood.
Long-Term Complications and Mortality
Long-term complications of diabetes, such as cardiovascular disease and chronic kidney disease, significantly contribute to the higher mortality rates observed in diabetic patients compared to the general population . Studies have shown that diabetic patients have a mortality rate 2-6 times higher than age- and sex-matched non-diabetic individuals, with complications like myocardial infarction and uremia being common causes of death. Additionally, the presence of persistent proteinuria is associated with a higher mortality rate.
End-of-Life Care for Diabetic Patients
End-of-life care for diabetic patients requires a holistic approach that balances glycemic management with the overall well-being of the patient. As patients near the end of life, strict glycemic targets may be relaxed to prioritize comfort and reduce the burden of treatment . Guidelines emphasize the importance of preventing symptomatic hypo- or hyperglycemia, minimizing blood glucose monitoring, and involving specialist diabetes teams in care planning. However, adherence to these guidelines is often inadequate, highlighting the need for improved education and support for healthcare providers.
Conclusion
Diabetes significantly impacts mortality rates worldwide, primarily through its long-term complications rather than acute metabolic emergencies. Regional disparities in access to care and insulin further exacerbate mortality rates in certain areas. Effective end-of-life care for diabetic patients requires a balanced approach that prioritizes patient comfort and holistic well-being. Addressing these challenges through improved care guidelines and support systems is essential to reduce the burden of diabetes-related deaths.
