Managing Fluctuating Blood Sugar Levels in Terminal Patients

Primary Goals of Care at End of Life

  • The American Diabetes Association recommends promoting comfort and controlling distressing symptoms, including pain, hypoglycemia, and hyperglycemia, in terminal patients 1
  • The primary goal is to avoid dehydration, emergency room visits, and hospitalizations, while preserving dignity and quality of life 1
  • Preventing hypoglycemia is the priority over preventing hyperglycemia in terminal patients, according to the American Diabetes Association 2

Patient-Specific Management Strategy

  • For stable terminal patients, the American Diabetes Association suggests continuing previous diabetes regimen with modifications, focusing primarily on preventing hypoglycemia, and keeping glucose levels below renal threshold (approximately 180-250 mg/dL) 2
  • For patients with organ failure, preventing hypoglycemia becomes paramount, and reducing or discontinuing agents that cause hypoglycemia is recommended 2
  • For actively dying patients, discontinuation of all diabetes medications is reasonable, and accepting glucose levels >250 mg/dL to minimize intervention burden is acceptable 6

Glucose Monitoring Modifications

  • The American Diabetes Association recommends dramatically reducing monitoring frequency based on patient status, with reduced monitoring for Type 2 diabetes in terminal care (twice daily or every 3 days) 1
  • For Type 1 diabetes, monitoring frequency may need to remain higher due to ketoacidosis risk 1

Treatment Simplification Strategies

  • The American Diabetes Association suggests simplifying medication regimens to reduce treatment burden and hypoglycemia risk, preferring oral glucose-lowering agents over complex insulin regimens 1
  • Using simplified insulin regimens with low hypoglycemia risk and discontinuing medications that increase hypoglycemia risk is recommended 2

Critical Pitfalls to Avoid

  • Overly tight glycemic control driven by quality metrics is a common error in terminal diabetes care, and healthcare providers should avoid this approach 4
  • Discomfort with reducing or stopping chronic medications is another pitfall, and providers must overcome reluctance to de-escalate therapy 4

Nutritional Considerations

  • Liberalizing diet restrictions to maintain comfort and nutrition is recommended, with elimination of "no concentrated sweets" or "no sugar" diet orders 5
  • Offering regular diet with preferred food items and avoiding therapeutic diets that decrease food intake and cause unintentional weight loss is suggested 5

Management of Comorbidities

  • Coordinating diabetes management with other end-of-life symptoms, such as managing pain from diabetic neuropathy and addressing depression and behavioral problems, is essential 1
  • Withdrawing lipid-lowering therapy to improve quality of life and relaxing blood pressure management targets may be considered 2
