Same-type reference in CA

Quality of patient care: this provider 2.5/5; median among 2,012 providers with a published value in the same state and provider category: 3/5.

CareRecords calculates this unweighted median from the loaded source snapshot. Providers with missing values are excluded. It is a descriptive reference, not a new quality rating or recommendation. Individual reporting periods may differ; do not compare different rating systems.

Questions to take to By the Bay Health

  • Ask which services are actually available now, who will provide them, and how the provider handles concerns outside normal office hours. Published quality data cannot confirm current availability.
  • Ask how the published quality of patient care relates to the reporting period and what has changed since then. Ratings for different kinds of care should not be compared.
  • For ownership entries below, ask which entity is the direct owner and which supplies management. An officer or managing employee is not necessarily an equity owner.
  • Check the source date and the latest official record before deciding. Bring the issues above to a visit or call rather than treating the profile as a recommendation.
