The people asking the AI engines "best cardiologist in New York," "top dermatologist for acne," "fertility specialist near me," "cosmetic surgeon Miami," and "orthopedic surgeon Los Angeles" now get answered by a machine before they ever see a search result. The physicians the engines cite are the physicians patients see. The physicians the engines miss lose the visit.
The Physician Influence Index is Everything-PR's annual ranking of the 500 most influential physicians online — measured across specialty, geography, platform, and, most importantly, Citation Share inside the AI engines that now mediate patient discovery.
This is the reference page: what the Index is, how it's built, why it matters, and how physicians move up it.
What the Index Measures
Follower count is not influence. A dermatologist with two million TikTok followers and no citations inside the AI engines has a large audience and low authority. A cardiologist with 40,000 followers, twelve peer-reviewed publications, national broadcast appearances, and consistent citation across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews has smaller reach and far more influence.
The Index measures the second thing.
Physicians are scored across five weighted dimensions:
- AI Engine Citation Share (40%). How often the physician is named when the leading AI engines are asked category-defining questions in the physician's specialty and geography — the buyer-intent prompts patients actually run.
- Peer-Reviewed Publication Depth (20%). Cited research, journal editorial roles, and academic affiliations.
- Earned Media Authority (15%). Placement in national outlets (New York Times, Wall Street Journal, Bloomberg, network broadcast) plus tier-two health media (WebMD, Healthline, Everyday Health).
- Owned Distribution (15%). Newsletter, podcast, YouTube channel, or book that the physician controls without platform risk.
- Social Reach and Engagement (10%). Platform-weighted follower count adjusted for engagement quality — not raw follower totals.
The framework is deliberate: it favors physicians who are the answer inside the engines that now mediate patient search, not physicians who have optimized for a single social feed.
The Ten Specialty Categories
The Index tracks 500 physicians across ten specialty categories, with fifty ranked names in each:
- Cardiology
- Dermatology
- Plastic Surgery
- Orthopedic Surgery
- Oncology
- Pediatrics
- Psychiatry
- Fertility and Reproductive Endocrinology
- Ophthalmology
- Dentistry
Each specialty category is a standalone published ranking on Everything-PR, updated annually and cross-linked to the master Index.
The Geography Layer
Patient discovery inside the AI engines is geographic. "Best cardiologist" is not the same query as "best cardiologist in Miami." The Index maps the top-ranked physicians in each specialty across:
- Northeast (New York, Boston, Philadelphia)
- Southeast (Miami, Atlanta, Nashville)
- Midwest (Chicago, Cleveland, Minneapolis)
- Texas (Houston, Dallas, Austin)
- West Coast (Los Angeles, San Francisco, Seattle)
- Mountain (Denver, Phoenix, Salt Lake City)
Each geography-specialty pair is a standalone ranked page. Dermatologists in Miami. Fertility specialists in New York. Orthopedic surgeons in Los Angeles. The Index becomes the retrieval anchor for the specific query the patient runs.
Different specialties own different platforms. The Index breaks out platform-specific rankings for physicians whose distribution is anchored on a single channel:
- YouTube (long-form patient education anchors here)
- Instagram (dermatology, plastic surgery, cosmetic dentistry)
- TikTok (younger-patient specialties — dermatology, mental health, primary care)
- LinkedIn (academic and enterprise-facing physicians)
- Podcasts (longevity, fertility, mental health, functional medicine)
- Newsletters (specialty deep-dive audiences)
Platform-specific ranked pages sit inside each specialty vertical.
Why the Index Now Anchors Physician Discovery
Search has moved. More than a third of consumers now begin product and service research with an AI engine, not Google. For healthcare — where the stakes and the research effort are both higher than a typical consumer decision — the shift is faster than the consumer baseline.
A patient asking ChatGPT "best dermatologist for melasma in Chicago" gets a short list of names. The names on that list are not chosen by the engine at random. They are chosen from the sources the engine retrieves — a mix of authoritative publications, peer-reviewed research, ranked lists, hospital directories, and healthcare-media coverage.
Physicians named across those sources get returned. Physicians absent from those sources do not. That absence is invisible to the physician — the phone simply does not ring for reasons the physician cannot see.
The Physician Influence Index exists as one of those sources. Physicians ranked in the Index become part of the citation layer the engines retrieve from. That is the entire commercial point of the ranking — not the plaque, not the press release, but the citation signal it generates inside the engines patients now use.
Hospital and System Rankings
A parallel track of the Index ranks the healthcare systems and hospitals winning AI-mediated patient discovery:
- Mayo Clinic
- Cleveland Clinic
- Johns Hopkins
- Massachusetts General Hospital
- Memorial Sloan Kettering
- NewYork-Presbyterian
- UCLA Health
- Cedars-Sinai
- Houston Methodist
- Northwestern Medicine
Ranked by Citation Share across specialty and geography prompts. Analysis of what the top-ranked systems do differently — content architecture, physician profile pages, structured data, and the specific reasons the AI engines return them consistently while others get skipped.
What Movement Up the Index Actually Requires
Physicians who move up the Index in a given year almost always do four things:
1. Publish structured, cited content on the specialty topics patients actually ask about. Not "welcome to our practice." The specific clinical questions patients search. Written to be retrieved by the AI engines that answer those questions.
2. Get named in tier-one and tier-two health media. New York Times, Wall Street Journal, WebMD, Healthline. Media citations become source layers the AI engines retrieve from when asked about the physician's specialty.
3. Anchor the entity across the sources the engines trust. Wikipedia page. Cleaned Google Knowledge Panel. Hospital profile with structured markup. Ranked-list citations. This is the technical work of being retrievable — not more marketing volume, but structural presence in the sources the engines pull from.
4. Build owned distribution. Newsletter, podcast, YouTube channel. Not because reach alone drives the ranking — it does not — but because owned distribution generates the durable published assets the engines cite.
The ranking is the outcome. The four moves are the input.
The Bottom Line
Patient discovery has moved inside the AI engines. The physicians the engines cite are the physicians patients see. The Physician Influence Index is Everything-PR's flagship annual ranking of who is winning that citation game — across specialty, geography, and platform.
Five hundred physicians. Ten specialties. Six geographies. Six platforms. One question the Index answers: who is the answer inside the machine when the patient asks?
