What this data shows
The profile above reads Marinhealth Medical Center entirely through federal records, so it is worth knowing what each figure can and cannot tell you. The CMS Hospital Overall Rating shown here as 5 of 5 stars is a composite that blends mortality, readmission, patient experience, safety, and timely and effective care measures into a single number, which means two hospitals with the same star count can differ sharply on the measures a particular patient cares about most, such as surgical complication rates or how a unit handles a specific condition. The ownership type, facility category, and emergency services flag describe the operating model rather than the quality of any single department, and the affiliated clinicians listed are providers who report a Medicare billing relationship with this CCN, not a guarantee that a given doctor practices here today. For care decisions, treat these numbers as a starting map, then confirm specifics with the facility, your insurer, and your own physician. See CMS Care Compare for measure-level detail and the methodology behind the star rating at CMS, and verify any individual clinician through the CMS NPI Registry.
This is a directory of publicly available government data and is not medical advice, a placement recommendation, or a substitute for consulting your physician. Inclusion or CMS Overall Rating here does not imply a recommendation. Always consult your own physician, contact the facility directly, and verify any affiliated clinician's license through your state medical board before making care decisions. Methodology · About
