Quality Improvement Project Reducing Sputum Cultures for Pediatric Patients With a Tracheostomy

Area of Science:

• Pediatric Medicine
• Quality Improvement Science
• Infectious Disease Diagnostics

Background:

• Overuse of diagnostic testing and overtreatment are concerns in pediatric tracheostomy care.
• Sputum cultures are frequently obtained in children with tracheostomies without clear guidelines or proven impact on management.
• Current practice suggests a need to optimize diagnostic strategies for this vulnerable population.

Purpose of the Study:

• To decrease the rate of sputum cultures in pediatric patients with tracheostomies by 50%.
• To implement and evaluate a quality improvement project aimed at reducing unnecessary diagnostic testing.
• To establish standardized decision-making for sputum culture collection in this patient group.

Main Methods:

• A single-center quality improvement project was conducted in a pediatric emergency department.
• An algorithm for sputum culture collection was developed and implemented, supported by electronic medical record modifications and education.
• Data on culture rates, length of stay, and emergency department return visits were collected pre- and post-intervention.

Main Results:

• The rate of sputum cultures decreased from 64% to 25%, exceeding the 50% reduction target.
• No significant changes were observed in patient length of stay or the rate of return emergency department visits.
• Statistical process control charts indicated a significant, nonrandom shift in culture rates post-intervention.

Conclusions:

• An algorithm effectively reduced the number of sputum cultures obtained in children with tracheostomies.
• The implemented changes demonstrate the feasibility of optimizing diagnostic testing protocols.
• Further research is warranted to assess the safety and efficacy of this algorithm in a broader patient population.
