The GCR Rating is computed from verified patient reviews, patient-reported outcomes and clinical results. How the Rating is calculated →
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 procedures such as angioplasty, stent placement and cardiac rhythm management — patients evaluating this category typically weigh clear communication about risk and realistic recovery timelines alongside the clinical outcome itself. See the full methodology for the exact formula.
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 cardiology clinics with the same Google star rating can end up with different GCR Ratings once volume and recency are factored in.
There's no fixed cutoff. GCR's Bayesian model pulls a clinic's average toward the cardiology 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.
Rankings are refreshed on a regular cycle as new verified reviews come in, so a cardiology clinic's position can move up or down over time as its underlying review data changes.
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.
