Optimizing a knowledge translation intervention using the Multiphase Optimization Strategy (MOST) design
ALL ARE WELCOME
SYNOPSIS:
Changing professional behavior is challenging. One example is the overuse and misuse of spinal imaging for spinal disorders, a well-recognized public health concern. We propose using an optimized audit and feedback (A&F) intervention enhanced with online educational messages from peer opinion leaders to reduce inappropriate spine x-ray in the largest CAM provider network in the US. The development of our optimized A&F intervention follows the 5-step systematic design of evidence-based interventions. Specifically, a fractional factorial trials with embedded process evaluations will be used, following the Multiphase Optimization Strategy (MOST) design to identify which components are active and to determine which combination of active components is the most effective optimized intervention. This will lead to a future randomized trial (confirming phase) to test the effectiveness of the optimized intervention for translating current spine x-ray guidelines into clinical practice.
OBJECTIVES:
- To discuss the design of an audit and feedback (A&F) report using theory-based program and delivery componentsÌýÌýÌý
- To describe strategies for testing the active components of the A&F with fractional factorial trials using the MOST design
- To discuss the design of a large randomized trial to test the effectiveness of the optimized A&F intervention on reducing spinal x-ray utilization rates.
