Elsevier has announced the acquisition of Wellsheet, a U.S.-based health technology company that specializes in aggregating and synthesizing patient data from electronic health records (EHR). The integration of Wellsheet’s validated EHR data model with Elsevier’s ClinicalKey AI will provide clinicians with verified, patient‑specific guidance directly within their workflows.
The combined offering is designed to address challenges identified in a 2026 McKinsey & Company healthcare study, which reported that more than half of U.S. healthcare leaders saw difficulty integrating generative AI into existing workflows as a major barrier to scaling. Clinicians often face complex patient records, evolving guidelines, and increasing documentation demands across disconnected tools. By combining Elsevier’s evidence base with Wellsheet’s data aggregation capabilities, the solution aims to deliver governed AI answers at the point of care.
Key features of the integrated platform include:
• Patient data aggregation to synthesize large volumes of information into a relevant patient view.
• ClinicalKey AI evidence surfacing peer‑reviewed content and guidelines traceable to their sources.
• Decision support for discharge planning, follow‑up actions, and reducing gaps in care.
Omry Bigger, President of Clinical Solutions at Elsevier, noted that clinicians face a tension between complex EHR systems and separate evidence sources, which costs time and introduces risk. He explained that combining Wellsheet’s EHR aggregation platform with ClinicalKey AI’s evidence base closes this gap by delivering patient‑specific guidance directly inside clinical workflows.
Craig Limoli, CEO and Co‑Founder of Wellsheet, stated that the partnership positions both companies to meet the complex needs of clinicians and hospital systems while scaling more rapidly. He emphasized that Wellsheet’s existing footprint across major EHR systems, combined with Elsevier’s global reach, provides a clear path to expand the capability to health systems worldwide.
Wellsheet will be integrated into Elsevier’s Clinical Solutions business, which supports clinicians, providers, and care teams in building competencies, making informed decisions, and engaging patients with evidence‑based information. Wellsheet is currently deployed across 139 hospital sites in the U.S. and integrated into major EHR systems.
Elsevier’s ClinicalKey AI is a clinical decision support solution used in more than 300 hospitals globally. It provides evidence‑based medical information, including full‑text content and clinical practice guidelines from over 1,000 journals and organizations such as The Lancet, Chest, Journal of Allergy and Clinical Immunology, Journal of Thoracic Oncology, and American Journal of Obstetrics and Gynecology, as well as guidelines from the American College of Cardiology, the American Association of Clinical Endocrinology, the European Society for Medical Oncology, and others.
