# Atlas Commons research objects — hospital quality for NASSAU UNIVERSITY MEDICAL CENTER

NASSAU UNIVERSITY MEDICAL CENTER (EAST MEADOW, NY) from CMS Care Compare, with each figure's status labeled: the CMS overall + HCAHPS star ratings are composites CMS computes (modeled, not direct measurements); the better/worse/no-different-than-national measure counts are CMS's published comparisons (recorded); the boundary note is context — CMS data, not a recommendation for your condition.

## Claims

### CMS gives NASSAU UNIVERSITY MEDICAL CENTER an overall hospital rating of 1 of 5 stars

**MODELED.** CMS rates NASSAU UNIVERSITY MEDICAL CENTER (EAST MEADOW, NY) at 1 of 5 stars overall. The CMS Overall Hospital Star Rating is a composite CMS COMPUTES from dozens of measures across mortality, safety, readmission, patient experience, and timely/effective care — an authority's model, NOT a single measured fact, and not a guarantee of any individual outcome.

Source: CMS Care Compare (Hospital) — https://www.medicare.gov/care-compare/
Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because CMS Care Compare (Hospital) (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### NASSAU UNIVERSITY MEDICAL CENTER has an average HCAHPS patient-experience rating of 1.1 of 5 stars

**MODELED.** Across the HCAHPS patient-experience survey domains, NASSAU UNIVERSITY MEDICAL CENTER averages 1.1 of 5 stars — how patients rated their care. A survey-based composite (modeled), not a clinical-outcome measurement.

Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because CMS Care Compare (Hospital) (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### Of 17 comparable measures, NASSAU UNIVERSITY MEDICAL CENTER is better than the national average on 0, worse on 2, no different on 15

**RECORDED.** On the quality measures with a national comparison, CMS records NASSAU UNIVERSITY MEDICAL CENTER as performing BETTER than the national average on 0, WORSE on 2, and NO DIFFERENT on 15 (of 124 measures reported in total; the remainder have no national comparison or too little data). These are CMS's published per-measure comparisons (recorded). "No different" is the most common result and is not a negative signal.

Source: CMS Care Compare (Hospital) — https://www.medicare.gov/care-compare/
Falsifier: A RECORD of measured/reported events (occurred=true) from CMS Care Compare (Hospital); superseded when CMS Care Compare (Hospital) publishes its next release.

### What this is — and is NOT — for NASSAU UNIVERSITY MEDICAL CENTER (the epistemic boundary)

**INTERPRETATION.** Every figure here is published CMS Care Compare data, the same facts CMS shows the public. The star ratings are CMS's MODEL; the measure-vs-national counts are CMS's RECORDED comparisons. This page INFORMS and COMPARES — it does NOT tell you which hospital is right for YOUR specific condition or procedure (that is for you and your clinician), and a star rating is not a guarantee of your outcome. For a specific procedure, ask about that hospital's volume and results. Verify everything at medicare.gov/care-compare.

Source: Care Atlas framing (over the CMS Care Compare facts above) — https://care-atlas.ryanjhunter.workers.dev/
Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (the atlas's reading, not a CMS verdict) — the lowest-warrant claim here. The CMS star ratings (modeled) and the measure-vs-national counts (recorded) above are CMS's own; this is the only interpretation.

Every claim above carries a four-status warrant (RECORDED / MODELED / DERIVED / INTERPRETATION) and a named source you can re-fetch — this is a research object, not a flat fact. Structured: `https://care-atlas.ryanjhunter.workers.dev/care/hospitals/330027.jsonld`
