CT Dose Optimization and Standardization Endeavor (DOSE) Collaboratory

University of California, San Francisco·interventional·Posted Dec 22, 2016·Updated Mar 8, 2024

In Brief

A clinical study evaluating Simple Audit Report, Multi-Component Intervention, and 1 other intervention for Ionizing Radiation Exposure and Quality Improvement. Completed, enrolled 864,080 participants.

Detailed Summary

This is a pragmatic stepped-wedge cluster randomized controlled trial to explore variation in doses used for diagnostic CT by pooling radiation dose data across diverse healthcare delivery systems. To compare different strategies for lowering and optimizing dose and identify the barriers and facilitators to implementing successful dose optimization strategies and standardizing practice.
