Recent advances in large language models and retrieval\u2011augmented generation (RAG) offer the possibility of accelerating consensus while maintaining methodological rigor. Large language models can retrieve and summarize evidence, but they frequently hallucinate and cannot reliably cite sources. At the same time, RNA\u2011based drugs and messenger RNA vaccines are rapidly moving from concept to clinic, generating a pressing need for timely, evidence\u2011based consensus on regulatory, manufacturing, and clinical issues.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>We evaluated whether a modular, RAG\u2011enabled, multi\u2011agent artificial intelligence (AI) pipeline could replicate the post\u2013round\u00a01 behavior of a human reviewer in a Delphi study. The primary objective was to determine whether AI\u2011assisted statement revision could rescue a greater proportion of subthreshold statements and achieve a consensus comparable to that obtained through human revision by round\u00a02.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A parallel, 2\u2011arm Delphi study was conducted on 28 statements about RNA medicines. In total, 50 international panelists (clinicians, researchers, and patient representatives) were randomized into human (arm\u00a0A) and AI\u2011assisted (arm\u00a0B) groups. After round\u00a01, statements below the 75% agreement threshold were revised either manually by human reviewers or by an AI pipeline comprising the following software agents: (1) ReferenceDetector, to identify external citations; (2) Summarizer, to produce structured summaries of supporting PDFs; (3) a hybrid RAG module that combined dense and sparse retrieval with cross\u2011encoder reranking; and (4) Refiner, which generated revised statements, reasoning logs, and explicit citations. Two human reviewers with expertise in Delphi methodology and literature review who had contributed to statement development verified retrieved citations and approved or amended revisions. Agreement rates and vote distributions were compared across arms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Arm\u00a0A reached consensus on 71.4% (20\/28) of the statements in round\u00a01, whereas arm\u00a0B reached consensus on 46.4% (13\/28). After revision, consensus increased to 92.9% (26\/28) of the statements in arm\u00a0A and 85.7% (24\/28) in arm\u00a0B. The AI arm exhibited a larger mean improvement (absolute difference between rounds 1 and 2=39.3\u00a0percentage points) because more statements were initially below the threshold. Nonetheless, the absolute difference between arms after round\u00a02 was modest (7.2\u00a0percentage points). AI\u2011assisted revisions were particularly effective for statements far below the threshold, but both arms failed to rescue 2 to 3 statements owing to substantive disagreements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A modular, citation\u2011anchored AI pipeline can closely approximate human performance in Delphi consensus procedures while substantially reducing manual workload. When paired with human oversight, AI assistance accelerated revision and closed most of the performance gap by the second round. Adoption of AI\u2011assisted workflows could accelerate consensus development on emerging technologies such as RNA therapeutics provided that transparency, rigorous retrieval, and human review are maintained.<\/jats:p>\n
