Evaluation Following Staggered Implementation of the "Rethinking Critical Care" ICU Care Bundle in a Multicenter...

Area of Science:

• Critical Care Medicine
• Healthcare Quality Improvement
• Patient Safety

Background:

• Implementing evidence-based care bundles in intensive care units (ICUs) is crucial for reducing complications.
• The Rethinking Critical Care (RCC) bundle targets common ICU issues like delirium, sedation, and mechanical ventilation.

Purpose of the Study:

• To assess process metrics and patient outcomes following the implementation of the RCC ICU care bundle in a community healthcare setting.
• To evaluate the impact of the RCC bundle on mortality and other key ICU indicators.

Main Methods:

• A retrospective interrupted time-series analysis was conducted across three Kaiser Permanente Northern California hospitals.
• Data from 24,886 ICU episodes (19,872 patients) admitted between January 2009 and August 2013 were analyzed.
• The RCC bundle was implemented in a staggered manner between October 2011 and November 2012.

Main Results:

• Post-implementation, compliance with certain process metrics (e.g., ventilation management) improved significantly.
• Unadjusted hospital mortality decreased from 12.3% to 10.9% (p < 0.01).
• Adjusted analysis showed a reduced odds ratio for hospital mortality (0.85) and 30-day mortality (0.88) post-implementation, though trend analysis did not show significant differences.

Conclusions:

• Implementation of the Rethinking Critical Care bundle was linked to practice changes and a 12-15% reduction in short-term mortality odds.
• The observed outcomes may represent mid-implementation effects and cannot be solely attributed to specific bundle elements.
• Further evaluation is needed as the implementation matures.
