Key takeaways
  • CoPlan introduces a contestable AI interface for healthcare, allowing clinicians and patients to challenge and revise AI-generated care plans.
  • The system uses a multi-agent workflow and role-based argument graphs to structure debates about care interventions.
  • Designed to improve transparency and trust in AI-assisted medical decision-making.
  • Published as an arXiv preprint, indicating early-stage research with potential for real-world adoption.
Full story

A team of researchers has developed CoPlan, a co-intelligent interface designed to support collaborative care planning between clinicians, patients, and caregivers. Unlike traditional AI systems that present recommendations as final outputs, CoPlan enables stakeholders to inspect, challenge, and revise plans when they conflict with clinical judgment or patient values. The system employs a multi-agent workflow where specialized AI agents generate candidate interventions, which are then organized into role-based contestable argument graphs. This structure allows users to engage in structured debates about the validity and feasibility of proposed care strategies, fostering greater transparency and trust in AI-assisted decision-making. The approach addresses a critical gap in healthcare AI, where fixed recommendations often fail to account for the nuanced, context-dependent nature of patient care.
