How to manage an elderly patient with uncontrolled T2DM, HTN, CKD stage 4, and multiple comorbidities, including cerebral infarction, depression, dementia, and an allergy to lisinopril, on a complex medication regimen?

Management of Elderly Patient with Uncontrolled T2DM, HTN, CKD Stage 4, and Multiple Comorbidities

This patient requires immediate implementation of a multidisciplinary team-based care model with a clinical pharmacist-led comprehensive medication review to address polypharmacy, optimize the existing regimen, and prioritize quality of life over aggressive disease-specific targets given the advanced CKD, cerebral infarction history, dementia, and high fall risk. 1

Immediate Priority Actions

Establish Multidisciplinary Team Coordination

• Assemble a coordinated team including the primary care physician, nephrologist, endocrinologist, clinical pharmacist, geriatric specialist, and social worker to create a unified care plan rather than applying multiple disease-specific guidelines that may conflict or cause harm. 1
• The clinical pharmacist should perform comprehensive medication management to assess each medication for appropriateness, effectiveness, safety, drug-drug interactions, and drug-disease interactions given CKD stage 4, orthostatic hypotension, fall history, and dementia. 2, 3, 4
• Coordinate care transitions and ensure all specialists communicate through a shared electronic health record to prevent prescribing cascades and duplicative therapies. 1

Define Patient-Centered Goals of Care

• Prioritize preserving quality of life, maintaining functional capacity, preventing falls and hospitalizations, and controlling symptoms over aggressive glycemic or blood pressure targets given the patient's dementia, cerebral infarction sequelae, protein-calorie malnutrition, and advanced CKD. 1
• Engage the patient (if cognitively able) and family/caregivers in shared decision-making to establish what matters most—likely avoiding hypoglycemia, falls, and maintaining independence rather than achieving tight HbA1c goals. 1
• Estimate prognosis using validated tools to determine which interventions will provide meaningful benefit within the patient's life expectancy, as aggressive targets may not be appropriate. 1, 5

Comprehensive Medication Review and Deprescribing Strategy

Identify Medications for Deprescribing

• Review all 15 current medications for appropriateness, potential harm, and alignment with goals of care. 1, 5
• High-priority candidates for deprescribing or dose reduction:
  • Simvastatin: Consider discontinuation given limited life expectancy from CKD stage 4, dementia, and cerebral infarction history, as statin benefits require years to manifest and may not align with patient's prognosis. 1, 5
  • Aspirin: Reassess indication given cerebral infarction history versus bleeding risk with CKD stage 4; if for secondary prevention, continue, but if primary prevention only, consider stopping. 4
  • Gabapentin: Requires dose adjustment for CKD stage 4 (typically 100-300 mg daily or every other day) to prevent sedation, falls, and cognitive worsening in this patient with dementia and fall history. 1
  • Trazodone: Increases fall risk through orthostatic hypotension and sedation; consider tapering given existing orthostatic hypotension and fludrocortisone use. 5, 6
  • Polyethylene glycol 3350 and sennosides-docusate sodium: Redundant bowel regimen; consolidate to single agent. 4

Address Drug-Disease Interactions

• Fludrocortisone and hydrocortisone: Clarify indication for both corticosteroids simultaneously; if for adrenal insufficiency, typically only one is needed. This combination may worsen hyperglycemia and hypertension. 1, 5
• Ipratropium-albuterol: Anticholinergic component (ipratropium) may worsen cognitive function in dementia and increase fall risk; consider albuterol alone if bronchodilator needed. 5, 6
• Dulaglutide: Appropriate GLP-1 agonist for T2DM with CKD and cardiovascular disease, but monitor for gastrointestinal side effects that could worsen dysphagia and protein-calorie malnutrition. 2

Optimize Blood Pressure Management

• Amlodipine is appropriate as monotherapy given lisinopril allergy, but verify blood pressure control and assess for excessive lowering that could worsen orthostatic hypotension and fall risk. 1
• Target blood pressure should be liberalized to 130-140/70-80 mmHg in this elderly patient with orthostatic hypotension, dementia, and fall history rather than aggressive <130/80 mmHg targets. 1
• Do not add additional antihypertensives (ARBs, other ACE inhibitors, or additional diuretics) given CKD stage 4, orthostatic hypotension, and lisinopril allergy limiting RAAS blockade options. 1, 7

Optimize Diabetes Management

• Liberalize glycemic targets to HbA1c 7.5-8.5% or fasting glucose 120-180 mg/dL to minimize hypoglycemia risk given dementia, CKD stage 4, protein-calorie malnutrition, and limited life expectancy. 1, 2
• Continue dulaglutide as it provides cardiovascular and renal protection without hypoglycemia risk, but monitor weight and nutritional status given existing protein-calorie malnutrition. 2
• Ensure glucagon availability is appropriate; verify patient/caregivers can recognize and treat hypoglycemia given dementia. 2

Ongoing Monitoring and Reassessment

Establish Regular Medication Reviews

• Reevaluate medication appropriateness at every healthcare transition (emergency department visits, hospitalizations, skilled nursing facility transfers) and at least quarterly in outpatient settings. 1, 5, 6
• Use interdisciplinary team assessment tools to monitor adherence, given 17 medications and dementia making complex regimens difficult to manage. 1, 5
• Simplify medication administration schedule by consolidating dosing times and using combination products where possible to improve adherence. 8, 3

Monitor for Adverse Drug Events

• Screen for medication-related problems at each visit: sedation, falls, orthostatic hypotension, hypoglycemia, worsening renal function, gastrointestinal symptoms affecting nutrition. 5, 6, 4
• Assess for prescribing cascades where drug side effects are misidentified as new conditions leading to additional prescriptions (e.g., metoclopramide for gastroparesis from dulaglutide). 5, 6
• Monitor renal function every 3 months given CKD stage 4; adjust medication doses as GFR declines. 7, 2

Critical Pitfalls to Avoid

Do Not Apply Single-Disease Guidelines Rigidly

• Avoid "guideline stacking" where implementing multiple disease-specific guidelines (diabetes, hypertension, CKD, cardiovascular disease) results in 20+ medications, increased adverse events, and treatment burden exceeding benefit. 1
• Disease-specific CPGs are not validated in patients with this degree of multimorbidity, dementia, and limited life expectancy. 1

Minimize High-Risk Medications

• Avoid adding medications with sedative or anticholinergic properties (benzodiazepines, first-generation antihistamines, tricyclic antidepressants) that increase fall risk in this patient with gait abnormality, muscle weakness, and fall history. 5, 6
• Do not add proton pump inhibitors without clear indication, as they are potentially inappropriate in older adults and increase fracture risk. 4

Address Pharmacokinetic Changes in CKD Stage 4

• All renally cleared medications require dose adjustment: gabapentin, potentially dulaglutide (though primarily hepatic), and any future additions. 1, 7
• Age-related changes in hepatic metabolism, body composition (increased fat, decreased water), and reduced albumin affect drug distribution and clearance, necessitating "start low, go slow" approach for any new medications. 1

Prevent Treatment Burden Exceeding Benefit

• Assess feasibility of the medication regimen given dementia, dysphagia, and caregiver availability; complex regimens increase nonadherence, adverse reactions, and reduce quality of life. 1, 8
• Consider discontinuing interventions unlikely to provide meaningful benefit within the patient's prognosis, particularly preventive medications requiring years for benefit (statins, bone-protective agents). 1, 5
