When establishing care for an 89-year-old female, what aspects should I focus on and which laboratory tests should be ordered?

Establishing Care for an 89-Year-Old Female: Focus Areas and Laboratory Testing

When establishing care for an 89-year-old female, apply the Geriatric 5Ms framework: assess Mind (cognition and mood), Mobility (falls and function), Medications (reconciliation and appropriateness), what Matters most to the patient (goals and preferences), and Multicomplexity (chronic conditions and social determinants). 1

Primary Assessment Framework

1. Mind: Cognitive and Psychological Assessment

Start here because cognitive status determines how you approach all other domains 1.

Specific actions:

• Screen for cognitive impairment using validated tools (e.g., Mini-Mental State Examination, Montreal Cognitive Assessment)
• Assess for depression using the 2-item Patient Health Questionnaire-2 2
• Evaluate for delirium risk factors
• Document baseline cognitive function to track changes over time

Rationale: Cognitive impairment affects medication adherence, fall risk, and the patient's ability to participate in advance care planning 1. Depression screening is recommended when support systems are available 2.

2. Mobility and Fall Risk

Ask the single most important screening question: "Have you fallen in the past year?" 2

Additional assessments:

• Observe gait and balance
• Evaluate use of assistive devices
• Assess basic Activities of Daily Living (ADLs): bathing, dressing, toileting, transferring, continence, feeding
• Assess Instrumental ADLs (IADLs): medication management, finances, transportation, meal preparation 3
• Screen for urinary incontinence with a 2-question tool 2

Falls directly impact mortality, morbidity, and quality of life through fractures, hospitalization, and loss of independence 1.

3. Medications: Comprehensive Review

Dedicate time to complete medication reconciliation, focusing on high-risk medications 1.

Priority areas:

• High-risk medications: Anticoagulants, antidiabetic agents (especially insulin and sulfonylureas), opioids 1
• Potentially inappropriate medications: Use American Geriatrics Society Beers Criteria or STOPP criteria 1, 2
• Anticholinergics, sedative-hypnotics, NSAIDs, antihypertensives, diuretics, psychotropics 1
• Assess for polypharmacy (>3 medications increases fall risk) 4
• Check for drug-drug and drug-disease interactions
• Consider undertreatment using START criteria 1

Common pitfall: Don't withhold beneficial medications based solely on age; consider functional status, cognitive status, and life expectancy 1.

4. What Matters Most: Patient Goals and Preferences

Establish the patient's health outcome goals and care preferences before making treatment decisions 1, 5.

Key discussions:

• Personal values and priorities
• Acceptable vs. unacceptable quality of life
• Goals for maintaining independence
• Living situation preferences
• Financial constraints and medication costs 3
• Identify surrogate decision-maker
• Initiate advance care planning documentation 1

This step provides the foundation for all medical decision-making and prevents pursuing interventions that don't align with patient priorities 1.

5. Multicomplexity: Chronic Conditions and Social Context

Evaluate how multiple chronic conditions intersect with social determinants of health 1.

Assessment areas:

• Current chronic medical conditions and their management
• Social support system and caregiver availability
• Living situation and safety
• Financial resources and insurance coverage
• Access to care and transportation
• Nutritional status and unintentional weight loss 2

Laboratory Testing Approach

For an 89-year-old establishing care, laboratory testing should be guided by existing conditions, symptoms, and what matters to the patient—not routine screening 5.

Essential Baseline Labs:

• Complete Blood Count: Screen for anemia, which contributes to frailty and functional decline 6, 7
• Comprehensive Metabolic Panel: Assess renal function (affects medication dosing), electrolytes, glucose
• Thyroid Function (TSH): Thyroid dysfunction contributes to frailty 7
• Vitamin D level: Vitamin D deficiency is strongly associated with frailty development 6, 7
• Hemoglobin A1c: If diabetic or at risk, to guide treatment intensity based on life expectancy

Conditional Testing Based on Conditions:

• Lipid panel: Only if results would change management given patient goals and life expectancy 3
• Vitamin B12: If cognitive impairment or anemia present
• Urinalysis: If urinary symptoms or recurrent infections

What NOT to Order:

Avoid routine screening tests that won't change management or align with patient goals, especially when life expectancy is limited 5. For example, cancer screening may not be appropriate if time-to-benefit exceeds life expectancy 1.

Additional Screening

• Vision and hearing: Rates of impairment increase with age, but insufficient evidence supports universal screening in asymptomatic patients 2. However, ask about functional impairment.
• Nutrition: Screen for unintentional weight loss and malnutrition 2
• Immunizations: Review and update (influenza, pneumococcal, COVID-19, shingles)

Critical Implementation Points

Avoid these common pitfalls:

1. Don't pursue disease-specific management without considering geriatric syndromes (frailty, falls, delirium) 1
2. Don't order labs reflexively—ensure results will inform decisions that matter to the patient 5
3. Don't assess domains in isolation—cognitive impairment affects medication adherence, which affects fall risk 1
4. Don't delay advance care planning discussions 1

Time-efficient strategy: Use pre-visit questionnaires for patients/families to self-assess risks, and train office staff to administer validated screening tools, allowing you to focus on identified problems 2.
