What interventions can be taken to minimize falls in an elderly patient with a history of embolic stroke, Non-ST-Elevation Myocardial Infarction (NSTEMI), stage 3 kidney disease (Impaired renal function), and currently taking bupropion (Wellbutrin)?

Fall Prevention in High-Risk Elderly Patient with Multiple Comorbidities

Implement a structured exercise program focusing on balance and gait training as the primary intervention, combined with comprehensive medication review (particularly addressing bupropion's seizure and fall risk), management of orthostatic hypotension, and home environmental modifications. 1, 2

Immediate Risk Assessment Required

Your patient requires urgent multifactorial falls risk assessment given the combination of stroke history, cardiovascular disease, renal impairment, and psychotropic medication use. 3, 2

Key assessment components to evaluate immediately:

• Gait and balance testing using standardized tools (Timed Up and Go test) 3, 4
• Orthostatic blood pressure measurements (critical given stroke and NSTEMI history) 3, 5
• Visual assessment 3, 2
• Cognitive screening for post-stroke deficits 3
• Medication review with specific attention to bupropion 1, 3
• Home environmental hazard evaluation 4, 5

Primary Intervention: Exercise Program (Highest Priority)

Exercise interventions reduce falls by 23% (rate ratio 0.77) and are the single most effective intervention. 2, 6

Specific exercise prescription:

• Supervised balance and functional training 3 sessions per week for minimum 10 weeks (longer duration shows better results) 4, 2
• Lower extremity strength training 4, 5
• Gait training 4, 5
• Consider Tai Chi with individual instruction as an evidence-based option 1, 5
• Must be administered by qualified physical therapist given stroke history 4, 5

The evidence strongly supports exercise over other single interventions, with consistent benefit across multiple high-quality guidelines and a 2024 meta-analysis of 59 RCTs. 2, 6

Critical Medication Management

Bupropion poses dual concerns requiring immediate attention:

Seizure risk with renal impairment: Stage 3 kidney disease increases bupropion levels and seizure risk, which independently increases fall risk. 1 Psychotropic medications consistently associate with falls across all settings. 1

Action required:

• Review bupropion dosing with nephrology input given stage 3 CKD 1
• Evaluate if depression management can be optimized with non-pharmacologic approaches or alternative agents with lower fall risk 1, 3
• Conduct comprehensive review of all medications, targeting reduction if patient takes ≥4 medications total 1
• Specifically assess for any benzodiazepines, neuroleptics, or other antidepressants 1

Medication reduction was a prominent component of effective fall-reducing interventions in community-based studies, though no RCTs exist for medication withdrawal as sole intervention. 1

Multifactorial Intervention Components

Multifactorial interventions reduce falls by 23% (rate ratio 0.77) in high-risk patients but require comprehensive implementation. 2

Essential components beyond exercise and medication review:

Orthostatic hypotension management (critical given NSTEMI/stroke):

• Measure blood pressure supine and after 1 and 3 minutes standing 3, 5
• Address if present through hydration, medication adjustment, compression stockings 5

Home environmental modifications:

• Occupational therapy home assessment with direct intervention (not assessment alone, which is ineffective) 5
• Remove tripping hazards, install grab bars, ensure adequate lighting 4
• Provide appropriate assistive devices (canes, walkers) as needed 1, 4

Visual assessment and correction:

• Formal vision testing if patient reports problems 1, 3
• Consider cataract surgery if indicated (reduces falls by 32%, RR 0.68) 2

Interventions to AVOID

Do NOT recommend vitamin D supplementation for fall prevention. 1, 6 The 2018 and 2024 USPSTF guidelines explicitly recommend against vitamin D for fall prevention (D recommendation) unless the patient has documented vitamin D deficiency or osteoporosis, which are different indications. 1, 6

Common pitfalls to avoid:

• Single-component interventions without comprehensive approach 5
• Home assessment without follow-up intervention or referrals (ineffective) 5
• Superficial assessment without management implementation 3
• Dismissing patient fall reports 3

Implementation Strategy

Multidisciplinary team approach required:

• Physical therapist for exercise program 4, 5
• Occupational therapist for home assessment 5
• Pharmacist for medication review 4
• Nurse care coordinator for follow-up 4

This comprehensive approach can reduce fall risk by 25-30% in high-risk populations when properly implemented. 1, 2

Monitoring and Follow-up

• Regular reassessment of fall incidents and near-falls 4
• Exercise program adherence monitoring 4
• Medication adherence and side effect monitoring 4
• Repeat gait and balance testing to assess intervention effectiveness 3, 4

The patient's multiple comorbidities (embolic stroke, NSTEMI, stage 3 CKD) place them in the highest risk category, making comprehensive multifactorial intervention with exercise as the cornerstone absolutely essential rather than optional. 2, 6
