Summary

Inadequate follow-up and incomplete tests contribute to diagnostic failures. This study examines a custom AI system designed to help the digital health team reliably identify patients needing follow-up and integrate findings into patient outreach. The AI agent improved detection of missed diagnoses in radiologist notes, patient outreach, and scheduling. By streamlining follow-up identification, the tool increased the chances of patients receiving timely care to improve outcomes in busy clinical environments.
