2/23/2021 Introduction Taking a Step Back is the Best Approximately one-quarter of people over the age of 65 years have diabetes and one-half of older adults have prediabetes. People with diabetes often have other chronic diseases such as Way to Move Forward – hypertension, cardiovascular disease and renal disease, neurological complications and are at increased risk of some forms of cancer that also affect life expectancy. However, the increasing prevalence of type 2 diabetes in young people means that the hospice demographic will also A Review of Diabetes Management at End-of-Life change. With the increasing prevalence of diabetes seen in the general population coupled with a large Christine Pham, Pharm.D., BCGP percentage of hospice patients admitted with comorbidities of cancer, cardiovascular disease, renal disease, and dementia, hospice clinicians should be prepared to be knowledgeable about the complexities involved in diabetes care at end-of-life. 1 2 Objectives Diabetes in Older Adults • Identify the goals of diabetes care in the hospice setting and how they align with the overall goals of hospice care • Increases the risk of common geriatric syndromes • Review signs and symptoms of hypo/hyperglycemia and how to adjust the • Cognitive impairment diabetic medication regimen to avoid potential severe, life-threatening events • Depression • Coordinate a safe and individualized approach to managing diabetes based on • Injurious Falls patient prognosis • Polypharmacy • Review the recommendations in the 2021 American Diabetes Association • Persistent pain Standards of Medical Care in Diabetes, as they pertain to the end-of-life • Urinary incontinence hospice population • Difficulty adhering to complex self-care regimen • Identify patient concerns around deintensification of the diabetes regimen, • Hypoglycemic events can cause further cognitive decline and vice versa using that to effectively demonstrate the benefit for liberalization • Less likely to benefit from reducing risk of microvascular complications (seen long-term) 3 4 American Diabetes Association - Older Adults: Goals of Diabetes Care at End-of Life Standards of Medical Care in Diabetes 2021 In a hospice patient, tight glycemic control not only has questionable benefit but has a clear potential to cause harm and significant morbidity.

Patients with organ dysfunction/failure will need to decrease insulin requirements. Insulin, and all diabetic medications, are stopped in Type 2 patients that are actively passing. • Any medication change (newly ordered or discontinued) should be evaluated to anticipate impact on glycemic control. The impact may not necessarily require adjustment in diabetic regimen if the patient is asymptomatic. 13 14 Management Strategies • Oral medications to manage diabetes are preferred, as are simplified insulin Dialogue with Patients regimens with low risk for hypoglycemia (No SSI) • Discontinue diabetes medications that carry risk of hypoglycemia (except for insulin in type 1 diabetics) • Discontinue diabetes medications that commonly cause nausea • Rapid-acting insulin may benefit patients who have erratic appetites or miss meals due to episodes of nausea or vomiting. Can be given after patient starts a meal. • Long-acting insulin may benefit patients with stable, daily nutritional intake. Adjust dose if food intake decreases or patient experiences weight loss. 15 16 Patient Perception and Concerns Overall Strategy and Clinician Approach • For some patients and families, careful attention to diabetes management may • Prepare yourselves – These conversations will be difficult, emotionally charged, be one of the few health-related activities they can maintain control over. and lengthy. • Patients have been educated about the importance of monitoring and strict • Upon enrollment into hospice, providers should discuss goals of care with glycemic control for years. patients and their families and the likely trajectory of glycemic treatment. • Suggestions to stop diabetes medications or blood glucose checks can be seen as • Frame these discussions therapeutically, clarifying that stopping or adjusting lack of concern or hastening the disease process. medications is being done to prevent harm and promote patient well-being. • Patient may become anxious about the effects of uncontrolled blood glucose and • Educate about the burdens and risks of tight diabetes management.
