ClinicalKey AI Enhanced: Trusted Medical AI with Expanded Content & Security

New York, February 18, 2026 – Elsevier has announced significant enhancements to ClinicalKey AI, its clinical decision support tool, addressing growing concerns among clinicians regarding the reliability and security of artificial intelligence in healthcare. The updates focus on expanding the tool’s content base and bolstering its technological infrastructure to provide more transparent and trustworthy AI-driven insights.

The integration of AI into healthcare has seen rapid growth, doubling in 2025, yet a recent report indicates that only 40% of clinicians currently trust these systems. This disparity highlights a critical need for AI solutions that prioritize transparency and accuracy. ClinicalKey AI aims to bridge this gap by building confidence through a foundation of robust evidence and rigorous verification processes.

A key improvement lies in the expansion of ClinicalKey AI’s content library. The platform now incorporates full-text content from leading medical journals and organizations, including The Lancet, the New England Journal of Medicine (NEJM), the European Society For Medical Oncology, and the American College of Cardiology. This provides clinicians with access to the broadest collection of trusted, evidence-based medical information available in a clinical AI solution.

Beyond content expansion, ClinicalKey AI now offers an unprecedented level of “traceability.” Clinicians can now pinpoint the exact source of information used to generate an answer, tracing responses not only to a specific paper or textbook but to the precise paragraph within that source. This feature is designed to reassure clinicians and build confidence in the tool’s accuracy, particularly at the point of care.

“I find ClinicalKey AI to be a very helpful source of information that facilitates optimal management of patients,” said Joseph W. St. Geme III, MD, Physician-in-Chief at the Children’s Hospital of Philadelphia. “This tool consistently provides detailed responses to queries and cites the references that support the responses, providing a high level of confidence in the accuracy of the information and making literature available to gather additional detail, if desired.”

The credibility of ClinicalKey AI is further strengthened by a “clinician-in-the-loop” approach. This involves a rigorous evaluation framework where licensed healthcare professionals assess the accuracy and clinical relevance of the tool’s responses, ensuring the highest quality of insights.

ClinicalKey AI’s expanded content includes over 130 curated, full-text premium journals, including titles such as Chest, the Journal of Allergy and Clinical Immunology, the Journal of Thoracic Oncology, and the American Journal of Obstetrics and Gynecology, with more additions planned. The platform also incorporates clinical practice guidelines from leading organizations like the American College of Cardiology, the American Association of Clinical Endocrinology, the American College of Emergency Physicians, and the American Gastroenterological Association.

Content is updated every 24 hours, ensuring clinicians have access to the most current information and guidelines. This verified content is then structured and linked, allowing for more precise and relevant answers in real-world clinical settings.

Dr. Vincenzo Defilippis, Head of Quality and Safety Department, Local Health Agency of Bari, Italy, emphasized the value of a trustworthy AI tool, stating, “Using ClinicalKey AI, our clinicians get great value from having a trustworthy AI tool to add to their toolbelt. This new version will enable us to ensure we deliver trusted AI intelligence to our clinicians backed by the world’s largest evidence-based and trusted content set.”

In addition to content enhancements, ClinicalKey AI introduces several new features designed to improve accessibility and usability. These include API-based integration options for compatibility with existing workflow tools, an upgraded user experience with a streamlined interface and improved navigation, native voice-to-text dictation in the mobile app, query history controls via a privacy panel, and the ability to easily toggle between adult and pediatric contexts.

Security and privacy are also paramount. ClinicalKey AI is designed to support HIPAA-compliant use, with built-in privacy and security controls to protect patient health information (PHI). A reading assistant, launching in March, will further support learning and curiosity by allowing clinicians to explore and engage with full-text articles.

Multi-language support and prompt sharing capabilities have also been added, broadening the tool’s accessibility and collaborative potential.

Omry Bigger, President of Clinical Solutions at Elsevier, stated, “Clinicians are navigating a complex and rapidly changing healthcare landscape and need solutions they can trust. The content and technology upgrades we’ve made to ClinicalKey AI build on our 140-year heritage of providing trusted medical content while also responding to the challenges faced by clinicians every day. We’re delighted that these additions make ClinicalKey AI the most comprehensive clinical decision support tool in the market.”

ClinicalKey AI is currently in use in over 300 hospitals worldwide, and these latest enhancements are expected to further solidify its position as a leading clinical decision support tool.
