Below: a structured answer to Is Adventist Health Sonora Good?. We pull from CMS public data — Inpatient Payment files, Hospital Compare measures, the Provider Data Catalog — and combine them through the LakeQuality value rubric. Every number is sourced and linked. Why this matters: U.S. hospital costs and quality vary by an order of magnitude between facilities for the same procedure, and the variation is not random — it correlates with hospital type, ownership, regional payment adjustments, and case mix. Understanding how to read the public CMS data is the difference between a defensible hospital choice and a coin flip.
The detailed answer below covers what the underlying data shows, the limitations of that data (the Medicare numbers do not directly tell you what commercial insurance pays, or what you will pay out of pocket), and how to translate the public numbers into the questions a patient or family actually has when comparing hospitals.
