110clinics ranked

95,103data points scored

Ranked by GCR Rating (out of 5). No stars, no review counts — one fair number per facility.

Compiled independently by GCR since 2012 from verified patient reviews — no clinic can pay to change its Rating. Most recent verified review: October 2026. How this data is verified →

GCR ranks 110 internal medicine clinics across 11 countries.
Each clinic's GCR Rating is computed from verified patient reviews using a Bayesian model that weighs rating, review volume and recency — not a simple average.
Clinics with fewer verified reviews are pulled toward the internal medicine specialty-wide average rather than excluded, so any clinic with verified reviews can be ranked.
Rankings are refreshed on a regular cycle as new verified reviews come in.

Frequently asked questions

What does the GCR Rating measure for internal medicine clinics?

The GCR Rating is computed from verified patient reviews — rating, volume and recency — using a Bayesian model, not a simple average, and that calculation is the same for every specialty GCR ranks. Clinics in this ranking provide general medical care, full-body health checks and preventive screening — since this category spans many types of visits rather than one procedure, patients typically weigh the thoroughness of the check-up and clarity in explaining results. See the full methodology for the exact formula.

Is the GCR Rating the same as a clinic's Google star rating?

No. The GCR Rating is a separate score (out of 5, to three decimals) computed from verified review rating, volume and recency using a Bayesian model — not a simple star average. Two internal medicine clinics with the same Google star rating can end up with different GCR Ratings once volume and recency are factored in.

Does an internal medicine clinic need a minimum number of reviews to be ranked?

There's no fixed cutoff. GCR's Bayesian model pulls a clinic's average toward the internal medicine specialty-wide mean in proportion to how few verified reviews it has — so a clinic with limited review history starts near the typical score for the specialty and earns its way up or down as more verified reviews accumulate, rather than being excluded outright.

How often is this ranking updated?

Rankings are refreshed on a regular cycle as new verified reviews come in, so an internal medicine clinic's position can move up or down over time as its underlying review data changes.

What does it mean if an internal medicine clinic isn't listed here?

GCR ranks clinics it has verified review data for. If a clinic you're considering isn't listed, you can suggest it for review — GCR will look into adding it once enough verified patient data is available.
