Elsevier has announced the acquisition of Wellsheet, a U.S.-based health technology company specializing in aggregating and synthesizing patient data from electronic health records to surface relevant clinical intelligence at the point of care. The combination of Wellsheet’s validated EHR data model and Elsevier’s ClinicalKey AI evidence base is designed to give clinicians verified, patient-specific guidance within their existing clinical workflows. Financial terms of the transaction were not disclosed.
Wellsheet is currently deployed across 139 hospital sites in the United States and integrated into major EHR systems, giving the combined entity an immediate footprint to build upon. Elsevier’s ClinicalKey AI is already in use in more than 300 hospitals worldwide, providing comprehensive evidence-based medical information from more than 1,000 medical journals and organizations including The Lancet series, the American College of Cardiology, the European Society for Medical Oncology, and others. Together, the integrated offering will aggregate and synthesize large volumes of patient data into a relevant clinical view, surface trusted peer-reviewed content with every response traceable to its source, and guide discharge planning, follow-up actions, and gap-in-care reduction — all inside the EHR workflow where clinical decisions are made.
The acquisition addresses a persistent and costly friction point in modern clinical practice. A 2026 McKinsey and Company healthcare study found that more than half of U.S. healthcare leaders cited difficulty integrating AI into existing workflows as the biggest barrier to scaling generative AI in healthcare. Clinicians today must navigate complex patient records, rapidly evolving guidelines, and growing documentation demands across disconnected tools — a gap Elsevier said introduces both time cost and clinical risk. Wellsheet will be integrated into Elsevier’s Clinical Solutions business, which supports clinicians and care teams across building clinical competencies, informed clinical decisions, and patient engagement.
Elsevier is part of RELX, a global provider of information-based analytics and decision tools, and has served academic and corporate research communities, healthcare professionals, and educators across 170 countries for more than a century.
KEY QUOTES:
“Clinicians today face a genuine tension: the patient data they need is in complex EHR systems, and the trusted evidence they need is somewhere else entirely. That gap costs time and introduces risk. By combining Wellsheet’s proven EHR data aggregation platform with ClinicalKey AI’s trusted evidence base, we’re closing it to deliver verified, patient-specific guidance directly inside the clinical workflow. For health systems, this means governed AI at the point of care, built on verified content clinicians can trust and patient context they already have.”
Omry Bigger, President, Clinical Solutions, Elsevier
“Elsevier and Wellsheet are well positioned to address the complex needs of clinicians and hospital systems and scale at a faster pace. Wellsheet is already available across major EHR systems, and that footprint, combined with Elsevier’s global reach, gives us a clear path to bring this capability to health systems everywhere. Together, we’re giving clinicians verified clinical insights and providing health systems with the consistency, security, and quality oversight they need to utilize AI with confidence.”
