Why the study?

Data on early mobilization following cardiac surgery were inadequate, despite proven benefits of early mobilization in general ICU patients.

Does early mobilization reduce the duration of mechanical ventilation and ICU length of stay in patients following cardiac surgery?

Population

159 patients assessed after cardiac surgery

Comparison

Early mobilization vs non-mobilized status

Design

Observational study

Follow-up

Until 7th day

Key result

Early mobilization within 24 hours of ICU admission after cardiac surgery significantly reduced ICU length of stay compared to non-mobilized patients (24 vs 47 hours).

Overview

Early mobilization was associated with shorter ICU stay; hypothesis-generating and requires RCTs before practice change.

Type

Observational (n=159)

No

Structured PICO

Does early mobilization reduce the duration of mechanical ventilation and ICU length of stay in patients following cardiac surgery?

P
Population
n=159 adult patients admitted to the Cardiac Surgery ICU within 24 hours of cardiac surgery and receiving mechanical ventilation. Median age 71, 65% male, single-center in Greece. Exclusions: severe obesity (BMI > 35kg/m2), open sternum, lobectomy, ECMO support, extensive peripheral thigh oedema, preexisting neuromuscular disease, and ICU readmission.
I
Intervention
Early mobilization consisting of active and passive limb mobilization, sitting in bed, and transferring from bed to chair, initiated during ICU stay (assessed on days 1, 3, 5, and 7).
C
Comparator
Non-mobilized (bedridden) patients receiving standard ICU care.
O
Outcome
Duration of mechanical ventilation (MV) support and ICU length of stay.

Main Result

Absolute Event Rate: 24% vs 47%

p-value: p=0.001

Early mobilization after cardiac surgery is associated with a significantly reduced duration of mechanical ventilation and shorter ICU length of stay.

Limitations

  • Small sample size for the observed effect size because most participants exited ICU shortly post-admission
  • Mobilization activities were recorded according to documented sessions, limiting real-time observation
  • Sedation, hemodynamic instability, and patient safety concerns constrained early mobilization
  • Observational design was not randomized and not designed to determine causal effects
  • Mobilization activities were recorded according to documented sessions which limited real-time observation
  • Sedation, hemodynamic instability and patient safety concerns constrained early mobilization
  • Non-randomized observational design

Cite This Study

Raidou et al. (2021) conducted an observational in Cardiac surgery (n=159). Early mobilization vs. Non-mobilized (bedridden) was evaluated on ICU length of stay (hours) (p=0.001). Early mobilization within 24 hours of ICU admission after cardiac surgery significantly reduced ICU length of stay compared to non-mobilized patients (24 vs 47 hours).
