Long-term sustainability of Washington State's quality improvement initiative for the management of pediatric spleen injuries

Long-term follow-up of Washington State's quality improvement initiative demonstrates sustained reduction in pediatric splenectomy rates for blunt spleen injuries, from 14.3% pre-intervention to 8.3% at 10-year follow-up. The study shows increased utilization of pediatric trauma centers and confirms that statewide QI initiatives can maintain clinical practice changes with minimal ongoing effort.
