1. Weaning and De-escalation Protocols

As patients stabilize, structured, symptom-driven tapers of sedatives, analgesics, and vasopressors reduce withdrawal risk, shorten ICU stay, and support ventilator liberation.

1.1 Sedation and Analgesia Tapering Algorithms

• Initial assessment: Monitor Richmond Agitation-Sedation Scale (RASS) every 4 hours, aiming for light sedation (RASS –2 to 0).
• Benzodiazepines: Decrease dose by 10–20% every 12–24 hours if the target RASS is achieved and no signs of withdrawal are present.
• Propofol: Reduce infusion rate by 5–10 mcg/kg/min every 8–12 hours under close hemodynamic monitoring.
• Opioids (e.g., fentanyl): Reduce by 1 mcg/kg/h every 8–12 hours; use equianalgesic tables for conversion to enteral agents.
• Adjunct α₂-agonists: Dexmedetomidine (0.2–0.7 mcg/kg/h) can blunt sympathetic overactivity during the taper.
• Pair daily spontaneous awakening trials (SAT) with spontaneous breathing trials (SBT) to accelerate liberation from sedation.

1.2 Vasopressor and Inotrope De-escalation Strategies

• Initiate wean: Begin when Mean Arterial Pressure (MAP) is ≥ 65 mm Hg for at least 4 hours, lactate is normalizing, and there are no signs of hypoperfusion.
• Tapering: Taper one agent at a time (e.g., decrease norepinephrine by 0.01–0.05 mcg/kg/min every 1–2 hours).
• Monitoring: Closely watch MAP, heart rate, urine output, and capillary refill. Pause the wean if MAP falls below 65 mm Hg or new signs of end-organ dysfunction appear.
• Response: Resume or slow the taper if hypotension, tachyarrhythmia, or a rise in lactate occurs.

1.3 Multistep, Parameter-Driven Protocol Implementation

• Embed criteria in order sets: sedation targets, MAP thresholds, and withdrawal score triggers.
• Define assessment frequency: vital signs every 15 minutes during an active wean, sedation scales every 4 hours, and withdrawal scales every 8 hours.
• Use electronic alerts for missed assessments and protocol deviations.
• Review weaning progress in daily interdisciplinary rounds.

2. Intravenous to Enteral Conversion

Transitioning to enteral therapy reduces line-associated risks and costs; however, dose calculations must account for bioavailability and patient-specific factors like organ dysfunction.

2.1 Equivalence Dosing and Formulation Selection

The primary step is to calculate the total 24-hour IV dose and then adjust for oral bioavailability to estimate the required enteral dose. This conversion requires careful consideration of drug properties and patient status.

Adjustments for hepatic dysfunction are critical; consider starting at 50–75% of the calculated dose. Prefer liquid formulations or immediate-release tablets for enteral tubes and never crush extended-release (ER) products.

2.2 Enteral Access and Administration

• Tube Types: Common types include nasogastric (NG), nasojejunal (NJ), and percutaneous endoscopic gastrostomy/jejunostomy (PEG/PEJ).
• Patency: Flush with 20–30 mL of water before and after each medication to maintain patency and ensure dose delivery.
• Formulations: Use liquid or water-soluble formulations for lipid-soluble drugs to prevent adherence to the tubing.
• Monitoring: Check gastric residual volumes and confirm tube position if malabsorption is suspected.

3. Post-ICU Syndrome (PICS) Prevention and Management

Early recognition and mitigation of Post-ICU Syndrome (PICS)—a constellation of cognitive, physical, and psychological impairments—are critical for improving long-term outcomes after critical illness.

3.1 Risk Stratification and Screening

• High-risk features: Sedation > 7 days, deep sedation (RASS ≤ –3), delirium, and prolonged immobilization.
• Screening at ICU discharge: Use validated tools such as the Montreal Cognitive Assessment (MoCA), ICU Mobility Scale, and Hospital Anxiety and Depression Scale (HADS).

3.2 The ABCDEF Bundle: Components and Evidence

The ABCDEF bundle is a multicomponent, evidence-based strategy proven to improve outcomes, including survival, and reduce delirium, ICU stay, and costs.

4. Medication Reconciliation and Discharge Counseling

A standardized handoff process, clear patient education, and timely outpatient arrangements are crucial to safeguard against medication errors and preventable readmissions.

4.1 Structured Handoff Checklists

A pharmacist-led Best Possible Medication History (BPMH) should be performed on admission and re-verified at discharge. This process involves a comprehensive review of the indication, dose, route, and duration of all pre-ICU and ICU-initiated therapies.

4.2 Patient and Family Education Tools

• Provide both written and verbal instructions covering each medication’s purpose, dosing schedule, and common side effects.
• Use the “teach-back” method to verify understanding and correct any misconceptions.

4.3 Outpatient Referral and Monitoring

• Coordinate primary care, specialty, and mental health referrals within 1–2 weeks of discharge.
• Schedule any necessary laboratory or therapeutic drug level checks (e.g., phenytoin trough) before the patient leaves the hospital.

4.4 Documentation and Communication Strategies

• Clearly document medication reconciliation outcomes and follow-up plans in the electronic health record (EHR).
• Send discharge summaries and direct notifications to outpatient providers to ensure seamless continuity.
