De-Implementation Strategies in Colorectal Cancer: Development, Implementation and Results of a Service-Oriented CDSS.

This study explores the development, implementation and preliminary results of an alert integrated into a EHR to de-implement unnecessary colonoscopies for patients aged 75 and older. From August 20 to November 29, 2024, the CDSS generated 567 alerts across 244 physicians and 499 patients. 91.8% of alerts were overridden and 7% were accepted. CDSS alerts to promote evidence-based care and reduce unnecessary procedures among older adults. Future work will focus on enhancing alert specificity and expanding de-implementation strategies to other practices.
