Abstract

Background Ambiguous or unnecessary radiologist recommendations for additional imaging (RAIs) can lead to excessive imaging use and diagnostic errors. Purpose To determine the cumulative impacts of multifaceted technology-enabled interventions aimed at optimizing RAI on RAI rate, actionability, and resolution over an 8-year period. Materials and Methods In this retrospective cohort study, conducted from January 2015 to December 2022, radiology reports from two tertiary hospitals (study site and control site) were analyzed. A series of quality improvement interventions, including radiologist education, electronic communication tools for tracking RAIs, and performance reports, were implemented at the study site but not at the control site. The RAI rate trend over time was compared between the sites using linear regression. Mixed-effects logistic regression was performed to assess the intervention impact on the RAI rate. RAI actionability and resolution were compared between the sites using the Fisher exact test.
