Episode 1- Mobilisation in the ICU

Summary
For much of critical care history, immobility was the norm: patients were sedated, kept still, and “protected.” But decades of research have revealed the hidden costs — profound muscle wasting, delirium, and long-term disability.

Jonathan explores how our understanding of mobilisation in ICU has evolved — from the recognition of harm caused by bedrest, to the first landmark studies proving that early movement is both feasible and beneficial.

From Bedrest to Better: Why Mobilise in ICU?

• ICU-acquired weakness: Patients can lose 15–20% of muscle mass within the first week of critical illness.

• Long-term outcomes: ARDS survivors tracked for five years showed persistent disability and reduced independence.

• Sedation & delirium: Deep sedation increases delirium risk; mobilisation reduces both incidence and duration.

• Physiological rationale: Even minimal movement supports cardiovascular tone, respiratory function, circulation, and cognition.

• Core message: Bedrest is not neutral — it is actively harmful. Mobilisation offers protection for both brain and body.

Proof in Practice: The First Mobilisation Trials

• Feasibility (Morris et al., 2008): Protocol-led mobilisation cut time to first mobilisation (5 vs 11 days), with no increase in adverse events.

• Landmark RCT (Schweickert et al., 2009):

  • Early PT/OT + daily sedation interruption vs SAT alone.

  • 59% vs 35% regained independence at discharge.

  • Patients had less delirium and spent fewer days ventilated.

• Implementation (Needham et al.): Demonstrated how embedding mobilisation into daily ICU practice improves outcomes and serves as a model for quality improvement.

• Core message: Early mobilisation is not only possible — it improves patient-centred outcomes safely.

Key Takeaways 

• Bedrest and heavy sedation accelerate weakness, delirium, and disability.

• Mobilisation is both biologically plausible and clinically effective.

• Early trials proved feasibility, safety, and functional benefits.

• Success requires:

  • Lighter sedation targets and daily SATs.

  • Interdisciplinary teamwork (nursing, PT/OT, medical).

  • Structured protocols and safety screens.

Overall message: Mobilisation should no longer be an afterthought in ICU. It is a therapeutic intervention — one that supports recovery, preserves dignity, and helps patients walk out of intensive care with more than just survival.
