Quality improvement project to improve adherence to lung protective ventilation guidelines

Area of Science:

• Critical Care Medicine
• Respiratory Therapy
• Quality Improvement Science

Background:

• Lung protective ventilation (LPV) is recommended for all mechanical ventilation (MV) patients to prevent lung injury.
• Previous interventions have shown success in increasing awareness and adherence to LPV guidelines.

Purpose of the Study:

• To evaluate the impact of a multi-component quality improvement project (QIP) on adherence to LPV guidelines.
• The QIP aimed to improve adherence through targeted interventions.

Main Methods:

• A retrospective analysis of MV data from a tertiary UK critical care unit was conducted.
• The study utilized Plan-Do-Study-Act cycles from September 2019 to August 2022.
• Interventions included LPV reports, bedside whiteboards, and targeted education.

Main Results:

• Over 400,000 hours of MV data were analyzed, showing improved LPV adherence post-QIP.
• Time spent with tidal volumes >10 mL/kg predicted body weight (PBW) decreased significantly.
• Adherence improved for both mandated and spontaneous MV, though not all targets were met.

Conclusions:

• A multi-component intervention effectively improved adherence to LPV guidelines.
• Further research is needed to analyze reasons for non-adherence and refine future interventions.
• Optimizing LPV adherence remains crucial for patient outcomes in critical care.
