1. Systemic Corticosteroid Tapering

Gradual steroid reduction is critical to minimize the risks of rebound inflammation and iatrogenic adrenal insufficiency. The speed of the taper should be individualized, reflecting the initial dose, duration of therapy, and severity of multisystem involvement.

Principles of Tapering

• Slow Taper (8–12 weeks): Recommended for patients on high-dose (>20 mg prednisone-equivalent) steroids for more than 3 weeks or those with severe organ involvement (e.g., fulminant hepatitis, myocarditis).
• Rapid Taper (4–6 weeks): May be appropriate for mild cases with a clear and sustained resolution of rash and normalization of laboratory markers.
• Dose Reduction Strategy:
  • Above physiologic range (>7.5 mg prednisone-equivalent), decrease the total daily dose by 10–20% every 5–7 days.
  • Below physiologic range, decrease by 5–10% every 7–10 days while closely monitoring for signs of adrenal insufficiency.

Monitoring During Taper

• Clinical Assessment (Twice-weekly): Monitor for rash recurrence, fever, and lymphadenopathy.
• Laboratory Monitoring (Weekly): Check eosinophil count, liver enzymes (ALT/AST), and renal function (BUN/creatinine).
• HPA Axis Assessment: Check a morning serum cortisol level once the prednisone dose is <7.5 mg/day to assess for HPA axis recovery.
• Bone Health: Obtain baseline bone density and vitamin D levels if the taper is expected to extend beyond 12 weeks.

2. IV-to-Oral Conversion

Transitioning from intravenous (IV) to oral (PO) immunosuppressants is a key step in de-escalating care. This process requires careful consideration of drug bioavailability, first-pass metabolism, and the patient’s enteral absorption capacity, which can be compromised in recovering ICU patients.

Equivalency and Bioavailability

Enteral Absorption Considerations

• Assess Gut Function: Confirm the presence of bowel sounds, stool output, and low gastric residual volumes before attempting conversion.
• Manage Impaired Motility: If ileus or high gastric residuals are present, delay PO conversion. Consider a post-pyloric feeding tube for medication administration.
• Monitor Drug Levels: For narrow-therapeutic-index agents like cyclosporine, monitor trough levels closely after converting to the enteral route.

3. Post-ICU Syndrome (PICS) Mitigation

Post-ICU Syndrome (PICS) is a constellation of new or worsened physical, cognitive, and psychological impairments that persist after critical illness. Proactive strategies like early mobilization and psychological support can significantly reduce PICS incidence and improve long-term outcomes.

Risk Factors for PICS

• Age >65 years
• Prolonged mechanical ventilation (>48 hours)
• High-dose corticosteroid therapy
• Presence of multi-organ dysfunction
• Delirium during the ICU stay

Early Mobilization Protocol

1. Day 1–2: Begin passive range of motion exercises as soon as the patient is hemodynamically stable.
2. Day 3–4: Progress to sitting at the edge of the bed.
3. Day 5–7: Advance to standing next to the bed and then assisted ambulation with physical therapy 1–2 times daily.
4. By ICU Discharge: Aim for independent walking and performance of activities of daily living (ADLs).

Psychological Support

• Screening: Use validated tools like the Patient Health Questionnaire-9 (PHQ-9) and Hospital Anxiety and Depression Scale (HADS) prior to ICU discharge.
• Intervention: Provide referrals for cognitive therapy and ensure family education on PICS.
• Follow-up: Arrange for an outpatient mental health follow-up within 2 weeks of hospital discharge.

Case Vignette: A 58-year-old DRESS survivor was extubated on ICU day 3. She began assisted sitting on day 4 and ambulation on day 6. Daily visits from a psychologist were associated with reports of reduced anxiety and improved coping.

4. Discharge Planning and Counseling

A structured, multidisciplinary discharge plan is essential to ensure a safe transition of care. This plan must include meticulous medication reconciliation, comprehensive patient education, and a clear schedule for follow-up with specialists and laboratory monitoring.

Medication Reconciliation

• Verify Taper Schedule: The exact steroid taper schedule must be clearly documented on discharge orders and prescriptions.
• Update Allergy List: Prominently record the DRESS-causing agent and known cross-reactivity risks in the patient’s electronic health record.
• Confirm Pharmacy Access: Ensure the patient’s outpatient pharmacy can stock and dispense all necessary medications.

Patient and Caregiver Education

• Provide a Written Taper Calendar: Give the patient a clear, written schedule with specific dates for dose changes and a list of warning signs of relapse.
• Educate on Self-Monitoring: Teach the patient and caregivers how to monitor for fever, new or worsening rash, and other symptoms.
• Establish a Point of Contact: Provide clear contact information for the clinical team for rapid advice if symptoms recur.

Follow-up Schedule

• Labs: Schedule weekly CBC with differential, LFTs, and BUN/creatinine for the first 4 weeks, then biweekly for the next 4 weeks.
• Specialist Visits: Arrange follow-up with Dermatology or Allergy/Immunology at 2 weeks, 6 weeks, and 3 months post-discharge.
• Primary Care: Ensure a follow-up visit with the primary care provider is scheduled within 1 week of discharge.
