Improving Appropriate Neurologic Prognostication after Cardiac Arrest. A Stepped Wedge Cluster Randomized Controlled...

Area of Science:

• Critical Care Medicine
• Neurology
• Clinical Trials

Background:

• Neurologic prognosis after out-of-hospital cardiac arrest (OHCA) is difficult to predict accurately.
• Inaccurate predictions can lead to premature withdrawal of life-sustaining treatments (LST), potentially harming patients who could have survived with good outcomes.

Purpose of the Study:

• To enhance adherence to guidelines for neurologic prognostication in OHCA patients.
• To reduce mortality associated with premature LST withdrawal.

Main Methods:

• A pragmatic stepped wedge cluster randomized controlled trial was conducted.
• A multifaceted quality intervention including education, pathways, local champions, and audit-feedback was evaluated.
• Appropriate neurologic prognostication was the primary outcome, defined by specific criteria regarding LST withdrawal and survival.

Main Results:

• The quality intervention led to increased rates of appropriate neurologic prognostication (68% to 74%).
• However, survival to hospital discharge and survival with good neurologic outcome showed no significant improvement.
• The intervention did not significantly alter the rates of survival to hospital discharge or good neurologic outcome.

Conclusions:

• A multicenter quality intervention successfully improved appropriate neurologic prognostication in OHCA survivors.
• The intervention did not translate into improved survival with good neurologic outcomes.
• Further research is needed to optimize prognostication and improve patient outcomes after OHCA.
