摘要: Background Despite guideline recommendations, vitamin D testing has increased substantially. Clinical decision support (CDS) presents an opportunity to reduce inappropriate laboratory testing. Objectives and Methods To of at the Vanderbilt University Medical Center, a CDS assigned providers receive or not electronic alert each time 25-hydroxyvitamin assay was ordered for adult patient unless order associated with diagnosis in patient's chart which is recommended. The ran 80 days, collecting data on number tests, provider information, basic demographics. Results During placed 12,368 orders D. intervention group received potentially 2,181 times completed 89.9% encounters, while control (without receiving alert) 2,032 98.1% absolute reduction 8% (p  Conclusion This reduced ordering by utilizing soft-stop approach. At charge $179.00 per test cost $4.20 test, display led average $14.70 charges $0.34 spending (the savings/alert ratio). By describing effectiveness terms ratio, impact this can be better appreciated compared other interventions.
