Reducing Erythrocyte Sedimentation Rate Ordering: De-implementation and Diagnostic Stewardship

The Choosing Wisely campaign recommends against the routine use of erythrocyte sedimentation rate (ESR) for the assessment of acute undiagnosed inflammation or infection. We examined ESR and C-reactive protein (CRP) ordering practices at a large, freestanding children's hospital. We found that 80% of ESR orders were placed concurrently with a CRP order. We aimed to reduce the ESR testing rate by 20% within 6 months in both inpatient and emergency department (ED) settings.
