Treatment algorithm reduces oxygen use in the Emergency Department

Area of Science:

• Emergency Medicine
• Respiratory Care
• Clinical Quality Improvement

Background:

• Unnecessary oxygen (O2) administration is common in Emergency Departments.
• Current recommendations provide a basis for optimizing O2 treatment protocols.
• Standardized algorithms can improve patient care and resource utilization.

Purpose of the Study:

• To evaluate an O2 treatment algorithm based on current guidelines.
• To reduce the number of patients receiving unnecessary O2 in the Emergency Department.
• To analyze the impact on O2 therapy use and associated adverse events.

Main Methods:

• A single-centre, pre- and post-intervention cohort study.
• Observation periods of 4 weeks before and after algorithm implementation.
• Key outcome measures included O2 treatment rates, indications, hypoxia, and hypercapnia.

Main Results:

• The proportion of patients receiving supplemental O2 decreased from 11% to 9% (18% relative reduction).
• Indications for O2 therapy remained consistent between the two periods.
• Adverse effects (hypoxia, hypercapnia) occurred with similar frequency and nature.

Conclusions:

• The O2 treatment algorithm effectively reduced unnecessary O2 administration in the Emergency Department.
• Algorithm implementation did not increase the frequency or type of adverse events.
• This approach supports evidence-based oxygen management in acute care settings.
