Diabetes Self-Management Education for an Older Adult with Cognitive Impairment
A 78-year-old woman with T2D for 15 years, hypertension, and mild cognitive impairment (MCI) lives alone. Her daughter visits weekly. Her medications: metformin 500 mg BID, glipizide 5 mg daily, lisinopril 10 mg daily, atorvastatin 20 mg daily. Her HbA1c is 8.1%. She has had two episodes of hypoglycemia (glucose 55 mg/dL) in the past month, one requiring assistance. She checks her glucose sporadically and often forgets if she took her medications. She has difficulty reading small print and sometimes skips meals due to poor appetite. Her BMI is 22 kg/m². She has no foot ulcers but has neuropathy. She is reluctant to attend group education classes.
1. What factors contribute to her hypoglycemia risk, and how would you adjust her diabetes medications?

Contributors: age, cognitive impairment leading to missed or duplicated doses, poor appetite and skipped meals, use of sulfonylurea (glipizide) which carries high hypoglycemia risk, and possibly declining renal function (not given but likely). Her HbA1c of 8.1% may not reflect average glucose due to variability. Adjustments: discontinue glipizide (or reduce drastically) due to hypoglycemia risk; consider replacing with a DPP-4 inhibitor or GLP-1 receptor agonist (if appropriate) or basal insulin with caution. Metformin can be continued if renal function is adequate (eGFR >30). Simplify regimen: once-daily dosing, use pill organizers, and involve daughter. Set less stringent glycemic goals (e.g., HbA1c 8–8.5%) due to hypoglycemia risk and cognitive impairment. Avoid sulfonylureas and insulin if possible. Recommend CGM if feasible to detect lows. Educate on consistent meal patterns and hypoglycemia treatment.
2. How would you tailor diabetes self-management education and support (DSMES) for this patient, considering her cognitive impairment and reluctance to attend group classes?

Tailor DSMES to her needs: use individualized, one-on-one sessions at home or via telehealth with her daughter present. Simplify content: focus on safety (hypoglycemia recognition and treatment, medication adherence), meal planning with easy-to-prepare foods, and foot care. Use large-print materials, pictures, and teach-back. Address cognitive impairment by using memory aids (pillbox, alarms, phone reminders) and involving her daughter in medication management. Set small, achievable goals. Address reluctance: explain benefits, offer choice of format, and build trust. Coordinate with her primary care provider and possibly a pharmacist for medication reconciliation. Reassess frequently and adjust as cognitive status changes. Provide emergency contact information and ensure she has glucagon if on insulin or sulfonylurea (though we plan to stop sulfonylurea). Document her preferences and support system.
