Quality Improvement in a Pediatric Echocardiography Laboratory: A Collaborative Process.

Area of Science:

• Pediatric Cardiology
• Medical Imaging
• Quality Improvement Science

Background:

• Transthoracic echocardiography (TTE) is crucial for diagnosing and managing congenital heart disease in children.
• Pediatric echocardiography faces unique challenges, including complex anatomy and variable patient cooperation, leading to diagnostic errors.
• Diagnostic errors in TTE can impact patient care and outcomes.

Purpose of the Study:

• To design and implement a collaborative, stepwise quality improvement (QI) process to reduce diagnostic errors in a pediatric echocardiography laboratory.
• To identify key areas for improvement in TTE diagnostic accuracy.
• To establish a measurable goal for error reduction and evaluate the effectiveness of implemented interventions.

Main Methods:

• Retrospective review of medical records for 100 pediatric cardiac surgery patients (≤ 5 years old) to identify diagnostic TTE errors.
• Collaborative root cause analysis involving sonographers and faculty to determine areas for improvement.
• Implementation of interventions focused on quality improvement processes and imaging.
• Follow-up assessment of error rates after intervention implementation.

Main Results:

• Eighteen diagnostic errors were identified in the initial 100 patients, with most having minor impact and being preventable.
• Root cause analysis identified 7 areas for improvement, with QI processes and imaging prioritized for intervention.
• An initial follow-up in 70 patients showed 7 errors, representing a 44% reduction in the diagnostic error rate.

Conclusions:

• A stepwise, team-based QI approach successfully reduced diagnostic errors in pediatric TTE.
• The developed QI initiatives demonstrate a feasible model for other echocardiography laboratories seeking to improve diagnostic accuracy.
• Collaborative efforts between sonographers and faculty are essential for effective quality improvement in pediatric echocardiography.
