1. Weaning & De-escalation of Intensive Therapies

As patients recover from critical viral illness, a systematic approach to liberating them from life support is crucial. Daily readiness assessments guide the weaning of mechanical ventilation and vasopressors, aiming to minimize iatrogenic harm and accelerate recovery.

Spontaneous Breathing Trial (SBT) Protocol

The SBT is a cornerstone of ventilator liberation. The process involves screening for readiness, conducting a timed trial, and evaluating for success or failure.

Following a successful SBT, clinicians assess for extubation readiness by confirming mental status, secretion control, and, in high-risk patients (e.g., intubated >7 days), performing a cuff-leak test to screen for laryngeal edema. For patients with ARDS, prophylactic non-invasive ventilation (NIV) may be considered post-extubation, with appropriate aerosol precautions.

Protocolized De-escalation Algorithm

A structured, multidisciplinary approach integrates weaning protocols. Daily rounds involving critical care pharmacists are key to identifying and overcoming barriers like excessive sedation or untreated infections.

2. Intravenous to Enteral Medication Conversion

Transitioning medications from intravenous (IV) to enteral (PO/NGT) routes is a key step in de-escalation. This process requires careful consideration of gastrointestinal function, drug bioavailability, potential interactions with enteral nutrition, and proper tube maintenance.

Assessment and Management

• Assess GI Function: Look for signs of GI dysfunction common in post-critical illness, such as reduced motility, mucosal edema, or low perfusion. If gastric retention is present, consider prokinetic agents like metoclopramide.
• Manage Feed-Drug Interactions: For drugs like phenytoin, fluoroquinolones, and levothyroxine, hold continuous enteral feeds for 1–2 hours before and after administration to ensure adequate absorption.
• Ensure Tube Patency: To prevent clogging, flush feeding tubes with 20–30 mL of water before and after each medication. If a clog occurs, use enzymatic decloggers first; tube replacement is a last resort.
• Timing and Monitoring: Initiate the IV-to-enteral switch once the patient tolerates enteral nutrition. Closely monitor clinical effects (e.g., blood pressure, sedation scores, INR) over the next 24–48 hours to ensure therapeutic equivalence.

3. Post-ICU Syndrome (PICS) Mitigation

Survivors of critical illness frequently suffer from Post-ICU Syndrome (PICS), a constellation of new or worsened impairments in physical, cognitive, and mental health. Proactive, bundled interventions are essential to reduce this long-term morbidity.

The ABCDEF Bundle

Implementing the ABCDEF bundle is a evidence-based, multidisciplinary strategy to improve patient outcomes. It focuses on integrating best practices for pain, sedation, delirium, and mobility.

• A
  Assess, prevent, and manage pain: Use validated pain scales (like CPOT) and a multimodal analgesia approach to minimize opioid use.
• B
  Both Spontaneous Awakening and Breathing trials: Coordinate daily sedation holidays with SBTs to facilitate ventilator liberation.
• C
  Choice of sedation: Prefer light sedation with agents like dexmedetomidine or propofol; avoid benzodiazepines, which are strongly linked to delirium.
• D
  Delirium prevention/management: Implement non-pharmacologic strategies like promoting normal sleep-wake cycles, reorientation, and using sensory aids. Limit antipsychotic use to cases of severe agitation.
• E
  Early mobility: Begin passive range of motion within 48 hours of admission and progress to active exercises and ambulation as tolerated.
• F
  Family engagement and psychosocial support: Involve family in care, provide regular updates, and support their role in the patient’s recovery.

4. Medication Reconciliation & Discharge Counseling

A meticulous medication reconciliation process and comprehensive patient education are critical safety measures during the transition from ICU to the ward and then to home. This prevents errors, supports adherence, and empowers patients to monitor for delayed complications.

Inpatient Review & Deprescribing

The first step is a thorough review of all medications. Compare the pre-admission medication list with the current ICU regimen. Actively deprescribe therapies that are no longer indicated, such as stress-ulcer prophylaxis (PPIs), antipsychotics, and sedatives. Use checklists to clearly document which medications were held, stopped, or changed, and create a clear plan for restarting chronic therapies.

Education Checklist for Discharge

Patient and caregiver education should be structured and confirmed with teach-back methods. Key topics include:

1. Antiviral Completion: Clearly explain the dosing schedule, potential side effects, and strategies to ensure the full course is completed.
2. Monitoring for Delayed Complications: Teach patients to watch for signs of post-viral sequelae, such as new or worsening dyspnea, leg swelling (thromboembolism), or cognitive changes (“brain fog”).
3. Escalation Protocol: Provide a clear, written plan with red-flag symptoms that should prompt a call to their provider or an emergency visit, including 24/7 contact numbers.

5. Seamless Transition to Outpatient Care

Ensuring a safe and effective transition from hospital to home requires structured handoffs, timely follow-up appointments, and the integration of technology like telemedicine to bridge gaps in care.

Structured Handoff and Coordination

Use a standardized handoff tool, such as the I-PASS mnemonic, to communicate critical information to outpatient providers:

• Illness severity
• Patient summary
• Action list (including pending labs, imaging, and medication changes)
• Situation awareness and contingency planning
• Synthesis by receiver

Coordinate with outpatient clinics to schedule follow-up appointments within 7–14 days of discharge. This should include primary care and any necessary specialists (e.g., infectious disease, pulmonology, rehabilitation).

Telemedicine Integration

Telehealth plays a vital role in post-discharge care, especially for patients in rural areas or with mobility challenges. It can be used for:

• Remote Monitoring: Tracking vital signs like pulse oximetry and blood pressure.
• Medication Adherence Checks: Virtual “pill counts” and counseling.
• Rehabilitation: Virtual cognitive and functional assessments and guided physical therapy.
