Common questions
- Which is more credible — Castle Connolly Top Doctor or a Vitals patient rating?
- They measure different things. Castle Connolly reflects peer professional regard — physicians choosing which colleagues they would refer patients to. Vitals reflects patient experience — how patients rated their encounters. Both are self-reported and neither is a regulatory credential. For clinical credentialing, state medical board licensure and CMS PECOS enrollment are authoritative.
- How do patients use Castle Connolly vs Vitals?
- Castle Connolly is primarily used when selecting a specialist for a complex or elective procedure where the patient wants peer-validated expertise. Vitals is used for general provider discovery when review volume and accessibility are the primary filters.
- Are these platforms' ratings independently auditable?
- Neither provides a publicly documented per-rating audit trail. Castle Connolly's selection criteria are described at a high level; Vitals' review collection methodology is not formally published. For independently auditable quality data, CMS Care Compare (for facilities) and state medical board disciplinary records (for individuals) are the primary sources.
- Do Castle Connolly or Vitals publish their data for research?
- Neither publishes bulk data or a public API for research. Federal primary sources — CMS NPPES, CMS Care Compare, CMS Open Payments — are the reproducible, publicly downloadable inputs for academic or policy research on provider quality.
