Resource stewardship and Choosing Wisely in a children's hospital.

Objectives: Evidence suggests that approximately 30% of the tests and treatments currently prescribed in healthcare are potentially unnecessary, may not add value, and in some cases cause harm. We describe the evolution of our hospital's Choosing Wisely (CW) program over the first 5 years of existence, highlighting the enablers, challenges, and overall lessons learned with the goal of informing other healthcare providers about implementing resource stewardship initiatives in paediatric healthcare settings.

Methods: We describe the development of de novo "top 5" CW lists of recommendations using anonymous surveys and Likert scale scoring. Composition and role of the steering committee, measurement of data and outcomes, and implementation strategies are outlined.

Results: Many projects have resulted in a successful decrease in inappropriate utilization while simultaneously monitoring for unintended consequences. Examples include respiratory viral testing in the emergency department (ED) decreased by greater than 80%; ankle radiographs for children with ankle injuries decreased from 88% to 54%; and use of IVIG for treatment of typical ITP cases decreased from 88% to 55%. Early involvement focused within General Paediatrics and the ED, but later expanded to include perioperative services and paediatric subspecialties.

Conclusions: An internally developed CW program in a children's hospital can reduce targeted areas of potentially unnecessary tests and treatments. Enablers include credible clinician champions, organizational leadership support, reliable measurement strategies, and dedicated resource stewardship education. The lessons learned may be generalizable to other paediatric healthcare settings and providers looking to introduce a similar approach to target unnecessary care in their own organizations.
