ICU discharge planning and transition of care: failures, criteria, and systems

Also known as ICU discharge planning · Transition of care · ICU step-down · Readmission · Post-ICU syndrome · ICU follow-up clinic · SBARR handover · Medication reconciliation

ICU discharge is a high-risk transition — one of the most dangerous handovers in hospital medicine. Premature discharge → readmission (roughly 6-10% of patients discharged alive from ICU) and markedly higher mortality (24.7% vs 4.0% in-hospital mortality among readmitted vs non-readmitted patients in Cooper's 28-hospital series); delayed discharge → ICU bed-blocking, increased cost, nosocomial infection, ICU-acquired weakness, and prolonged delirium. READMISSION RISK FACTORS: respiratory (day-of-discharge hypoxaemia, hypercapnia, or complex respiratory nursing needs), neurological (day-of-discharge neurologic impairment — GCS), severity and workload (higher acute physiology score at discharge — APS over 40; longer ICU stay; deterioration on the ward before ICU admission), and OPERATIONAL (after-hours discharge 18:00-06:00 → higher readmission and mortality, adjusted OR 1.34-1.42 in ANZICS data — Gantner 2014, Pilcher 2007; UK night discharge more often judged premature — Goldfrad 2000). STRUCTURED DISCHARGE PLANNING rests on five pillars: (1) OBJECTIVE READINESS CRITERIA — resolving organ failure, stable haemodynamics without escalating vasopressors, adequate ventilation without hypoxaemia or hypercapnia, neurologically appropriate (baseline mental state, delirium controlled). (2) PHARMACIST-LED MEDICATION RECONCILIATION — stop ICU-only drugs (sedatives, NMBA), restart held home meds (beta-blockers, statins, anticonvulsants — adjust for recovering renal/hepatic function), correct durations (antibiotics, steroid taper), avoid indefinite gastric prophylaxis. (3) STRUCTURED HANDOVER — SBARR (Situation, Background, Assessment, Recommendation, Read-back) or ISBAR, written + verbal, with explicit acceptance of care by the receiving team. (4) TIMING — discharge in daytime (ideally before 16:00, before 18:00 at latest), avoid night discharge; if unavoidable, enhanced handover + document rationale. (5) POST-DISCHARGE FOLLOW-UP — ICU follow-up clinic at 2-8 weeks to screen for POST-INTENSIVE CARE SYNDROME (PICS): cognitive impairment (memory, executive function, attention — affects ~30-40%, persists at 1yr in 25%), psychological morbidity (depression 30%, PTSD 20%, anxiety 40% — combined physical/cognitive/mental health impairment affects 50-70% at 1 year), and physical weakness (ICU-acquired weakness CIP/CIM 25-50%). PREVENTION of PICS: ABCDEF bundle (Assess pain, Both spontaneous awakening/breathing trials, Choice of analgesia/sedation, Delirium monitoring, Early mobility, Family engagement) — Pun 2019 ICU Liberation Collaborative (15,000+ patients) showed lower mortality, more coma-/delirium-free days, and higher discharge home. FAMILY morbidity (PICS-Family) is also common — depression, anxiety, PTSD, caregiver burden.
