Mount Sinai ranks #16 with a Citation Share Index score of 55 in the Citation Share Report: The Hospitals & Health Systems Audit, an AI visibility study of 25 US hospitals. The score places Mount Sinai in the middle of the leaderboard, below Hospital of the University of Pennsylvania (#15, 58) and ahead of Houston Methodist (#17, 52). Mount Sinai holds Honor Roll status in the analysis, drawn from the 2025-2026 US News Best Hospitals Honor Roll.
What the Hospitals & Health Systems Audit Measures
The Citation Share Report: The Hospitals & Health Systems Audit measures how often and how prominently hospitals surface in answers from AI engines. Researchers ran 60+ healthcare prompts across six categories through ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, then modeled a directional Citation Share from cross-engine knowledge synthesis with primary-source verification, using the EPR Citation Share five-component formula. The panel of retrieval sources spans US News & World Report Best Hospitals, Newsweek World's Best Hospitals, Healthgrades, Wikipedia, Leapfrog Hospital Safety Grade, NIH funding databases, Becker's Hospital Review, Modern Healthcare, NYT Health, STAT News, NPR Health, CMS Hospital Compare, Castle Connolly Top Doctors, the NCI-Designated Cancer Center list, and hospitals' own .edu, .org, and .com domains.
The study selected 25 hospitals based on inclusion in the 2025-2026 US News Best Hospitals Honor Roll, plus four specialty institutions (MSK, MD Anderson, Boston Children's, CHOP) and Vanderbilt. Honor Roll status was verified against US News Best Hospitals 2025-2026, released July 29, 2025.
Why Mount Sinai Ranks #16
Mount Sinai's score of 55 sits in the middle of the 25-hospital field. The index identifies a clear top tier: the original Honor Roll heavyweights, Mayo, Cleveland Clinic, Hopkins, Mass General, UCLA, UCSF, and NewYork-Presbyterian, command more than 60% of all "best hospital" citation share, despite US News alphabetizing the Honor Roll. Mount Sinai, at #16 with a 55, places behind that group and behind fellow New York institutions NewYork-Presbyterian (#6, 79) and NYU Langone (#9, 71).
According to the index, five signals move citation share: US News specialty ranking elevation, named-physician programs, condition-explainer content depth, Newsweek global ranking inclusion, and NIH/NCI designation surfacing. The index also identifies four shared weaknesses that drive low citation share at the bottom of the leaderboard: no named-specialty leadership, weak owned-content libraries, geographic asymmetry away from major coastal media markets, and no Newsweek dual-anchoring.
One of those signals connects directly to Mount Sinai's own reported standing. Newsweek's World's Best Hospitals 2026 list ranked The Mount Sinai Hospital No. 1 in New York for the fourth year in a row, and placed it No. 22 in the world, No. 7 nationally, and No. 1 in New York State and New York City. The index notes that Newsweek's World's Best Hospitals is the only ranking source that has gained AI citation share against US News in the last 24 months, and that Newsweek global ranking inclusion is one of the five signals that move citation share.
How Newsweek Dual-Anchoring Shapes the Position
The index treats US News as the dominant retrieval anchor while singling out Newsweek as the ranking source gaining ground against it. That framing gives weight to Mount Sinai's Newsweek results, where it reports being No. 1 in New York for the fourth year in a row and No. 22 in the world on the World's Best Hospitals 2026 list. In the index's terms, Newsweek dual-anchoring is one of the four factors whose absence drags scores down at the bottom of the leaderboard, making a documented Newsweek global ranking a relevant input to citation share.
Mount Sinai's research output also intersects with the signals the index tracks. The Mount Sinai Health System was ranked among top global leaders in health care research by the Nature Index, and its newsroom carries a steady flow of research releases, including work on a fully human monoclonal antibody cocktail that protects against Nipah and Hendra viruses, the Ross Procedure in a wide range of adults with aortic valve disease, and social determinants of health in predicting common diseases. The index counts condition-explainer content depth and NIH/NCI designation surfacing among the signals that move citation share.
Where Mount Sinai Sits in the Broader Hospitals Story
The index describes how each engine anchors differently: ChatGPT anchors to brand premium and Wikipedia; Claude is closest to expert physician judgment and discipline-specific; Perplexity is heavily US News-anchored; Gemini weights Google's Knowledge Graph and patient-volume signals; and Google AI Overviews is the most US News-driven and fastest to reflect new Honor Roll entrants. The index also finds that institutional medicine sources are increasingly favored by AI for high-stakes prompts over experiential community sources such as Reddit, Healthline, and patient forums.
For Mount Sinai, a mid-table Citation Share Index score of 55 reflects a position below the top-tier Honor Roll heavyweights and below its New York peers NewYork-Presbyterian and NYU Langone. With Newsweek inclusion, named-physician recognition, and research depth among the five signals the index says move citation share, Mount Sinai's reported strengths align with the levers the study identifies for building AI citation share over the multi-year horizon it describes.
