The system uses procedural skills and explicit contracts to ensure consistent decision-making across workflow stages, addressing challenges like data representation and temporal interpretation. It outperformed retrieval-based methods, achieving 95.1% accuracy in producing required cohort outputs after requirement clarification, compared to 60.4% with retrieval from the same procedural corpus.\n\nVTHarness was tested in three synthetic environments and eight MIMIC-IV tasks, demonstrating improved source recovery across three language models. It also enabled reference-matched cohort execution in Mayo Clinic cases, supporting investigator review of cohort construction and endpoint analysis. The framework aims to streamline virtual trial implementation by coordinating procedural guidance with workflow decisions.","keyPoints":["VirtualTrialHarness (VTHarness) automates virtual clinical trial protocol execution using procedural skills and contracts","Outperformed retrieval methods with 95.1% accuracy in producing required cohort outputs after clarification","Tested in synthetic environments and Mayo Clinic’s Virtual Trials Program for investigator review"],"whyItMatters":"VTHarness could accelerate virtual clinical trials by reducing manual effort in protocol execution and ensuring consistency across complex workflows, potentially lowering costs and improving trial reliability.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":[],"models":[],"people":[]},"firstPublishedAt":"2026-11-05T05:00:00Z","updatedAt":"2026-11-05T05:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"VirtualTrialHarness: Coordinating Agentic Operationalization of Virtual Trial Protocols Across Complex Clinical Schemas","url":"https://arxiv.org/abs/2611.05551","publishedAt":"2026-11-05T05:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Researchers release VirtualTrialHarness for virtual clinical trial workflows\", 5 November 2026, https://digestai.news/story/researchers-release-virtualtrialharness-for-virtual-clinical-trial-wor","publisher":"Digest AI","title":"Researchers release VirtualTrialHarness for virtual clinical trial workflows","datePublished":"2026-11-05T05:00:00Z","url":"https://digestai.news/story/researchers-release-virtualtrialharness-for-virtual-clinical-trial-wor"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
