Restrictive vs Liberal Physical Restraint Strategies in Critically Ill Patients: The R2D2-ICU Randomized Clinical...

Area of Science:

• Critical Care Medicine
• Patient Safety
• Mechanical Ventilation

Background:

• The impact of physical restraints, specifically wrist straps, on outcomes for mechanically ventilated patients in the ICU is not well-established.
• Understanding the optimal strategy for using physical restraints is crucial for improving patient care and safety.

Purpose of the Study:

• To evaluate the effectiveness of a restrictive, low-use wrist-strap physical restraint strategy versus a liberal, high-use strategy in critically ill patients requiring invasive mechanical ventilation.
• To determine if a less frequent use of wrist straps impacts key patient outcomes.

Main Methods:

• An open-label randomized clinical trial involving 405 adult patients across 10 ICUs in France.
• Patients were assigned to either a low-use restraint strategy (avoiding straps unless severe agitation present) or a high-use strategy (systematic application and daily reassessment).
• Primary outcome was days alive without coma or delirium within 14 days post-randomization.

Main Results:

• No significant difference was observed in the mean days alive without coma or delirium between the low-use (6.67 days) and high-use (6.30 days) strategy groups (adjusted mean difference: 0.37 days; P=.51).
• The incidence of self-extubation was similar in both groups (9.2% low-use vs. 8.5% high-use).
• Day-90 mortality was 37.2% in the low-use group and 41.0% in the high-use group.

Conclusions:

• A low-use wrist-strap physical restraint strategy did not demonstrate a benefit over a high-use strategy in reducing days free of coma or delirium in mechanically ventilated ICU patients.
• The findings suggest that current practices regarding the use of wrist straps in this population may not significantly alter key neurological and safety outcomes.
• Further research may be needed to explore alternative non-restraint strategies for managing agitation and preventing adverse events in ventilated patients.
