Therapy De-escalation and Transition of Care

1. Principles of Therapy Weaning

Structured de-escalation of systemic immunomodulators prevents rebound inflammation and minimizes iatrogenic harm. A taper should be initiated only when skin and mucosal lesions have stabilized and inflammatory markers have normalized.

Initiation Criteria

• No new target lesions for at least 72 hours
• Evidence of healing mucosal erosions
• Stable hemodynamics and normalizing inflammatory laboratory values

Risks of Rapid vs. Slow Tapering

• Rapid Taper Risks: Adrenal insufficiency (presenting as fatigue, hypotension, hyponatremia) and disease flare requiring re-escalation of therapy.
• Slow Taper Risks: Prolonged immunosuppression leading to increased risk of infection, hyperglycemia, and steroid-induced myopathy.

2. Systemic Corticosteroid Taper Protocols

A successful taper involves transitioning from high-dose intravenous pulses to maintenance and then enteral dosing, with individualized taper speeds based on disease severity and clinical response.

Pulse to Maintenance to Oral

A typical protocol begins with IV methylprednisolone 500–1,000 mg/day for 3 days, followed by a lower IV dose of 0.5–1 mg/kg/day for 3–5 days, before converting to an equivalent oral prednisone dose.

Monitoring During Taper

• Conduct a daily skin and mucosal exam to watch for signs of relapse.
• Check a morning cortisol level when the prednisone dose is ≤ 10 mg/day to assess HPA axis function.

3. IV-to-Enteral Corticosteroid Conversion

A safe switch from intravenous (IV) to enteral corticosteroids requires accurate dose conversion, consideration of bioavailability, and proper administration practices, especially for patients with feeding tubes.

Bioavailability and Conversion

• Bioavailability: Oral prednisone and prednisolone have 70–90% bioavailability, while methylprednisolone is approximately 80% bioavailable.
• Conversion Ratios: Methylprednisolone 4 mg is equivalent to Prednisone 5 mg, which is equivalent to Hydrocortisone 20 mg.

Administration via Feeding Tube

• Use immediate-release tablets (crushed and mixed with water) or liquid formulations.
• Flush the feeding tube with 15–30 mL of water before and after administration.
• Avoid mixing the medication directly with enteral nutrition formulas, as this can affect drug stability and absorption.

4. Mitigating Post-ICU Syndrome (PICS)

Early identification and multidisciplinary interventions are crucial to reduce the long-term physical, cognitive, and psychological sequelae in high-risk ICU survivors. Patients with prolonged mechanical ventilation (>7 days), sepsis, multi-organ dysfunction, or prolonged sedation are at highest risk.

Key Interventions

• Early Mobilization: Initiate passive or active range-of-motion exercises within 48–72 hours of stabilization. Set daily goals, such as sitting in a chair, transferring, and ambulating for at least 20 minutes.
• Cognitive & Psychological Support: Implement daily sedation interruptions and perform routine delirium screening (e.g., CAM-ICU). Use ICU diaries and family orientation protocols to reduce anxiety and disorientation.
• Multidisciplinary Rounds: Conduct dedicated PICS rounds involving pharmacy, physical/occupational therapy, psychology, and nursing to create a collaborative care plan.

5. Medication Reconciliation and Discharge Counseling

Pharmacist-led medication reconciliation and structured patient counseling at ICU discharge are high-impact interventions that reduce medication errors and preventable hospital readmissions.

Patient and Caregiver Education

Use the “teach-back” method to confirm understanding of:

• Dosing schedules, administration routes, and key side effects (e.g., hyperglycemia, signs of adrenal insufficiency).
• Warning signs that warrant a call to the clinic, such as hypotension, new fever, or rash recurrence.

Tools and Follow-up

• Counseling Tools: Use standardized discharge checklists and medication packets. Integrate pharmacy counseling notes directly into the electronic health record (EHR) discharge summary.
• Follow-up Call: A pharmacist-led phone call 48–72 hours post-discharge can clarify confusion and address early problems.

6. Transitional Care Planning

Coordinated outpatient follow-up and the use of remote monitoring technologies are key to ensuring continuity of both dermatologic and pharmacologic care after a complex hospitalization.

Outpatient Follow-up

• Schedule follow-up appointments with both dermatology and primary care within 7–14 days of discharge.
• Provide clear instructions for laboratory monitoring, such as checking morning cortisol when prednisone is ≤ 5 mg/day and weekly fasting glucose and electrolytes until steroid cessation.

Telehealth and Home Health

• Utilize telehealth for remote assessment of skin lesions and for medication counseling.
• Arrange for home health services for patients who require ongoing wound or feeding tube care, or for early physical therapy.

7. Key Clinical Decision Points and Pitfalls

Navigating the transition of care requires astute clinical judgment to distinguish relapse from expected healing, avoid iatrogenic harm from unnecessary medications, and ensure flawless communication between care teams.

Relapse vs. Post-Inflammatory Changes

• Relapse: The appearance of new, active target lesions. This requires re-escalation of the corticosteroid dose.
• Post-Inflammatory Change: Stable, hyperpigmented macules without blistering or erosion. This is part of the healing process and does not require a change in therapy.

Avoiding Polypharmacy

At discharge, critically reevaluate the need for medications started in the ICU. Discontinue therapies that are no longer indicated, such as:

• Stress ulcer prophylaxis (e.g., proton pump inhibitors)
• Venous thromboembolism (VTE) prophylaxis (if patient is ambulatory)
• Empiric antibiotics
