CMS Care Compare
What it is. The Centers for Medicare & Medicaid Services publish hospital and provider quality measures, including Complications and Deaths and Healthcare-Associated Infections.
How ProxiSuite uses it. Feeds the Clinical lens and the Clinical ProxiScore, using CMS’s own national comparisons, shown as reported.
Nursing home beds. Unlike the hospital file, the CMS nursing home file publishes a certified bed count directly on every provider. Post-acute bed counts are that published CMS figure, used exactly as reported, and are labeled as a real published count rather than resolved through the hospital chain above.
CMS Cost Reports and Provider of Services
What it is. Public financial and certification filings, including operating margin, total margin and certified bed counts.
How ProxiSuite uses it. Feed the Financial and Size lenses. CMS Hospital General Information does not publish beds at all, so every hospital bed count in ProxiSuite comes from one of three filings, and the one it came from travels with it.
How a hospital bed count is chosen. In this order, and the first one that exists wins.
Certified. The Provider of Services certified bed count, CRTFD_BED_CNT. Beds a CMS certification actually stands behind. This is the number nearly every hospital shows.
Physical. The Provider of Services total bed count, BED_CNT. Every physical bed in the building, including areas that are not certified and not participating in Medicare. It is a real count of a different thing, not a better version of the certified one, so it is labeled separately and only used where no certified count was filed.
Cost report. The audited bed count from the facility's own Medicare cost report. Used only where the Provider of Services file carries neither figure.
Certified and physical are both shown where both were filed, because they answer different questions. Nothing is ever interpolated or modeled: where none of the three carries a bed count, the facility shows none rather than a guess.
HIFLD Open Hospitals
What it is. Homeland Infrastructure Foundation-Level Data, a public national hospital layer originally published by the Department of Homeland Security. The official HIFLD Open portal was deactivated in August 2025, so this reads a stable public mirror of the same layer hosted by NASA.
How ProxiSuite uses it. It no longer supplies bed counts. HIFLD carries no CCN, so each hospital had to be matched on normalized name plus ZIP with a name and city fallback, and a fuzzy match to a third-party layer older than CMS is not a certified bed count. It was a last resort, it never overrode a CMS or Provider of Services figure, and it has been retired from the bed chain entirely: a hospital with no certified, physical or cost report count now shows no beds rather than a matched estimate. The layer is still read for facility identity and location.
CMS Open Payments
What it is. A public transparency database of payments from manufacturers to providers and teaching hospitals.
How ProxiSuite uses it. Powers the Payments lens and the who-pays panel. Records are shown exactly as reported. A payment is not evidence of wrongdoing.
AHRQ Patient Safety Indicators
What it is. The Agency for Healthcare Research and Quality publishes the Patient Safety Indicators (PSI), a standardized set of measures for in-hospital complications and adverse events.
How ProxiSuite uses it. Defines the patient-safety measures in the Clinical report and Clinical ProxiScore, applied to each facility's own reported CMS figures and shown as reported.
US Census Bureau, American Community Survey
What it is. Public demographic and population estimates by geography.
How ProxiSuite uses it. Feeds the Community and Market lenses and area context.
CDC PLACES
What it is. The Centers for Disease Control and Prevention publish PLACES, model-based estimates of chronic-disease and health-risk prevalence at small-area (ZCTA) grain.
How ProxiSuite uses it. Feeds a community-health sub-index inside the Community lens, shown as modeled estimates, not counts.
HRSA
What it is. Health Resources and Services Administration data on Health Professional Shortage Areas.
How ProxiSuite uses it. Feeds the Shortage lens at county grain.
IPEDS and College Scorecard
What it is. US Department of Education datasets on institutions, enrollment, completion, and outcomes.
How ProxiSuite uses it. Feed the Outcomes lens.
Urban Institute Education Data Portal
What it is. A free API from the Urban Institute that republishes federal education data, including the NCES files below, in one place you can actually query.
How ProxiSuite uses it. It is the pipe every education read goes through, for both K-12 and colleges. The data underneath is federal. The delivery is theirs. If their API is down, the product says so rather than showing you a number it guessed.
NCES Common Core of Data
What it is. The Department of Education’s annual census of every public school and district in the country.
How ProxiSuite uses it. Feeds school records: enrollment, grade span, locale and the district each school rolls up to. Read through the Urban Institute portal above, not scraped.
USAspending
What it is. The federal government’s public record of contract, grant and other award spending.
How ProxiSuite uses it. Feeds the Awards lens, resolved to accounts through ProxiMatch and badged with the confidence of that match. Award dollars are what was obligated to an organization, not what it is worth to you.
NPPES
What it is. The National Plan and Provider Enumeration System, the public NPI registry.
How ProxiSuite uses it. Provides provider identity and NPI lookup. Names are public registry data used as account context, not a people directory.
FDA openFDA (Device)
What it is. The US Food and Drug Administration’s public device datasets: Product Classification, Registration and Listing, Recalls and Enforcement, and 510(k) clearances.
How ProxiSuite uses it. Powers Industry Focus: the national manufacturer and brand list, plus recall and clearance signals shown as reported. This is establishment and regulatory data, not a ProxiSuite assessment of any product’s quality.
OpenStreetMap
What it is. An open, community-built map of the world, licensed under the Open Database License.
How ProxiSuite uses it. Provides base map tiles. Map data is © OpenStreetMap contributors.
Geoapify
What it is. A commercial geospatial service for routing, drive-time, and isochrones.
How ProxiSuite uses it. Provides real drive-distance and routing behind the proximity engine, used under Geoapify’s terms.
