What is the appropriate management plan for a patient with multiple complex medical conditions including hypoxemia, severe malnutrition, skin injuries, and chronic comorbidities?

Management of Complex Multimorbidity in Skilled Nursing Facility

This patient requires a structured, priority-based approach centered on patient preferences, prognosis, and feasibility of interventions, with coordinated multidisciplinary care to address the 23 concurrent conditions while avoiding treatment burden and polypharmacy complications. 1

Core Management Framework

Establish Patient-Centered Priorities

• Elicit and document the patient's goals of care explicitly, focusing on whether the priority is symptom management, functional preservation, or life prolongation, as this frail patient with severe malnutrition and multiple wounds has uncertain prognosis 1
• Conduct a time-limited prognosis assessment (short-term <1 year, mid-term <5 years) to guide which interventions are likely to provide meaningful benefit versus those with time-to-benefit exceeding life expectancy 1, 2
• Document specific patient preferences regarding trade-offs between treatment burden (23 medications, multiple therapies, wound care) and potential benefits, as treatment complexity itself worsens outcomes in multimorbid patients 3, 4

Implement Coordinated Team-Based Care

• Designate a primary coordinating clinician (the SNF physician in this case) to serve as the medical home, synthesizing all health problems and establishing treatment priorities across the 23 conditions 1, 2
• Establish regular multidisciplinary team conferences including nursing, PT/OT, speech therapy, dietary, pharmacy, and wound care to ensure all interventions are aligned with overall goals and not working at cross-purposes 1, 2
• Partner explicitly with a clinical pharmacist for comprehensive medication review given the extensive polypharmacy and high risk of prescribing cascades (e.g., mirtazapine added for appetite, which may worsen confusion and fall risk) 1, 2

Priority-Based Condition Management

Tier 1: Life-Threatening/High Morbidity Issues

Severe Protein-Calorie Malnutrition (Priority #1)

• Malnutrition is the primary driver of wound non-healing, infection risk, and functional decline in this patient and must be addressed before other interventions can succeed 5, 6
• The severely low prealbumin and rapid weight loss indicate acute nutritional crisis requiring aggressive intervention beyond current supplements 5
• Investigate and address reversible causes of poor appetite: thyroid abnormalities (low T3 uptake), medication side effects (multiple CNS-active drugs), depression, and oral/dental problems 6
• Consider time-limited trial of appetite stimulants (mirtazapine already initiated), but monitor closely for sedation worsening fall risk and oxygen desaturation 1
• If oral intake remains inadequate despite optimization, discuss goals of care regarding enteral nutrition, as continued severe malnutrition will prevent wound healing and increase mortality 5, 6

Pressure Injuries and Skin Tears (Priority #2)

• Wound healing is impossible without adequate nutrition; the unstageable spine wound and recurrent skin tears will not improve until protein-calorie malnutrition is corrected 5, 6
• Continue current wound care protocols but recognize these are temporizing measures until nutritional status improves 5
• The appearance of new skin tears despite protective measures suggests skin fragility from malnutrition and requires investigation of transfer techniques and caregiver education 5

Hypoxemia with Non-Adherence (Priority #3)

• The recurrent oxygen removal despite desaturation <92% suggests either discomfort, confusion, or underlying goals-of-care misalignment that requires direct discussion with patient and family 1
• Evaluate whether continuous oxygen aligns with patient's stated priorities; if comfort-focused care is the goal, intermittent oxygen PRN for dyspnea may be more appropriate than forced continuous use 1
• If oxygen is deemed necessary for symptom management, address barriers: nasal irritation (humidification, different delivery device), confusion (behavioral interventions, not restraints), or patient preference 1

Tier 2: Conditions Requiring Medication Review

Polypharmacy Rationalization

• This patient is on 20+ medications for 23 conditions, creating high risk for adverse effects, drug-drug interactions, and prescribing cascades 1, 2
• Conduct systematic medication review asking for each drug: Does the time-to-benefit align with prognosis? Does the benefit outweigh harms in this frail patient? Is this treating another drug's side effect? 1
• Specific deprescribing considerations:
  • Statins: unlikely to provide benefit within 1-2 year timeframe in severely malnourished patient; consider discontinuation 1
  • Vitamin D 50,000 units: excessive dose may contribute to hypercalcemia and confusion; reassess need 1
  • Multiple CNS-active drugs (mirtazapine, oxybutynin, acetaminophen, gabapentin): cumulative anticholinergic and sedative burden increases fall risk and confusion 1
  • Anticoagulation (apixaban): reassess risk-benefit given fall risk, bleeding risk, and goals of care 1

Fall Risk Mitigation

• The combination of gait impairment, confusion, polypharmacy with CNS-active drugs, oxygen tubing, and malnutrition creates extreme fall risk 1
• Rather than adding more interventions, reduce medication-related fall risk by tapering sedating medications one at a time with monitoring 1, 2
• The calling-out behavior may represent unmet needs (pain, toileting, anxiety) rather than requiring medication; investigate and address root causes 1

Tier 3: Chronic Conditions Requiring Maintenance

Cardiovascular Conditions (HTN, AFib, CAD)

• Continue current cardiac regimen but monitor for hypotension given malnutrition, dehydration, and low body weight which may necessitate dose reductions 1
• Blood pressure targets should be liberalized in this frail patient (goal <150/90) to avoid orthostatic hypotension and falls 1

Chronic Kidney Disease

• The elevated BUN with stable creatinine suggests prerenal azotemia from dehydration/catabolism rather than worsening CKD 1
• Encourage oral hydration but avoid aggressive IV hydration which may worsen heart failure symptoms if present 1

Critical Implementation Considerations

Avoid Common Pitfalls

• Do not apply single-disease guidelines rigidly to this patient; for example, tight glycemic control guidelines do not apply to severely malnourished patients with limited life expectancy 1
• Recognize that adding interventions for each condition cumulatively creates treatment burden that may exceed the patient's capacity to adhere, worsening outcomes 1, 3
• Beware of prescribing cascades: mirtazapine added for appetite may cause sedation leading to falls, which might prompt consideration of fall-prevention medications, creating a harmful cycle 1

Monitor for Treatment Burden

• Assess whether the current 23-condition management plan is feasible for this patient with cognitive impairment and poor oral intake 2, 3
• The extensive therapy schedule (PT/OT/ST multiple times weekly), wound care, medication administration, and monitoring may be overwhelming and counterproductive 2
• Consider consolidating or reducing intervention frequency if the burden is preventing rest, oral intake, or causing distress 1, 2

Communication and Documentation

• Document explicitly the rationale for each treatment decision, including why certain guideline-recommended interventions are being withheld or modified based on patient-specific factors 1
• Hold regular family conferences to ensure alignment between the intensive treatment plan and patient/family goals, particularly given the severity of malnutrition and wounds 1
• If the patient's condition continues to decline despite optimal management, revisit goals of care and consider whether transition to comfort-focused care is more appropriate 1

System-Level Interventions

• Ensure nursing staff understand the priority is nutritional intake and wound healing, not rigid adherence to all 23 condition-specific protocols 2
• Create a simplified medication administration schedule to reduce pill burden and improve adherence 2
• Implement systematic tracking of key outcomes (weight, wound measurements, functional status) rather than disease-specific metrics that may not be relevant 2
