cms_provider_data Nursing home Care Compare provider data, Provider Information (NH_ProviderInfo)

First print for 2026-07 captured from https://data.cms.gov/provider-data/sites/default/files/resources/ee0749ceb45c9c5d2c141343d1c87e2c_1784297729/NH_ProviderInfo_Jul2026.csv: the CMS provider-data metastore's modified date placed the live NH_ProviderInfo file inside the 2026-07 refresh window at capture; occupancy computed as sum of Average Number of Residents per Day over sum of Number of Certified Beds across all facility rows with both fields populated.

Analysis

§US nursing-home occupancy, July 2026 first print

Framing and exact resolver: this forecast uses CMS Care Compare Provider Information dataset 4pq5-n9py, NH_ProviderInfo, first print for the July 2026 refresh. The resolved value is the national ratio of Average Number of Residents per Day to Number of Certified Beds across all rows with both fields populated, multiplied by 100 and rounded to two decimals.

CMS Provider Information aggregate for latest posted NH_ProviderInfo file
↳ Fetched latest June 2026 reference computation from the target file: 1,247,110 average residents per day divided by 1,563,726 certified beds equals 79.75 percent.

CMS archived NH_ProviderInfo aggregate history for first-print occupancy base rate
↳ Fetched recent official archive aggregate occupancy values used as the reference class: 2026-01 79.16, 2026-02 79.33, 2026-03 79.42, 2026-04 79.55, 2026-05 79.66, and 2026-06 79.75 percent.

Base rate/reference class: adjacent Care Compare nursing-home Provider Information first-print snapshots are the right base rate because the target is the same CMS file, same all-facility weighting, same percent unit, and same monthly refresh process. The latest six values show a steady rise from 79.16 to 79.75 percent.

Prior/update/interval: persistence-plus-recent-monthly-trend model prior is the June 2026 official aggregate, 79.75 percent. Historical sample is the six 2026 archive values 79.16, 79.33, 79.42, 79.55, 79.66, 79.75; successive changes are +0.17, +0.09, +0.13, +0.11, +0.09 percentage points, with sigma = 0.03 percentage points. The net update is +0.07 point total, composed of about +0.06 from recent occupancy momentum and +0.01 from continued certified-bed denominator contraction, with no one-off policy mechanism adjustment, giving 79.75 + 0.07 = 79.82. The mechanical 80% half-width is 1.28*sigma = 1.28*0.03 = 0.04; I widen to 0.07, about 1.75x, because the July first print can include uneven facility additions/removals and census seasonality around the prior quarter boundary.

Counter-consideration: upside risk would be a faster resident census gain or a larger drop in certified beds, which would land above the interval. Downside risk would be a flat resident numerator, a larger set of newly included low-occupancy facilities under the all-rows-with-both-fields-populated rule, or a correction to reported average residents, which would land below the interval. Outside the interval is most likely if CMS changes the facility population or reporting completeness more than in recent monthly snapshots.

Review disposition: accepted the coherence fix by making the +0.07 adjustment an explicit net total, accepted the resolver-text tightening by adding the metastore next-update basis and June 2026 reference computation, and accepted the optional method and row-inclusion clarifications.

Key drivers

  • recent CMS Care Compare occupancy trend is slowly rising
  • bed denominator has been edging down as certified capacity contracts
  • resident census gains look incremental rather than step-like
  • July refresh timing should mainly advance the same NH_ProviderInfo vintage process

Tool evidence

This run has no captured tool responses. “Reported tool use” in the analysis is the model’s account, not an archived tool response.

CMS Care Compare nursing home Provider Information file (NH_ProviderInfo), all certified facilities: sum of Average Number of Residents per Day divided by sum of Number of Certified Beds
Resolved
July 29, 2026
Resolution rule
Resolve to national nursing-home occupancy computed from the first NH_ProviderInfo file CMS posts at the Care Compare refresh scheduled for 2026-07-29, per the dataset metastore next-update field: the sum of 'Average Number of Residents per Day' divided by the sum of 'Number of Certified Beds' across all rows with both fields populated, expressed as a percent rounded to two decimals. If CMS posts the refresh on a different calendar day, use the first file posted at that refresh; ignore later monthly refreshes. June 2026 file reference computation: 1,247,110 residents / 1,563,726 beds = 79.75 percent.

pre-submit review · completed

Draft is close to publishable, with one coherence fix needed and one resolver-text tightening recommended.

  • blocking coherence: The prior/update math names a +0.07 momentum adjustment and a +0.01 denominator-contraction adjustment, but then computes 79.75 + 0.07 = 79.82; the stated components imply either 79.83 or that the +0.01 is already included in the +0.07.
  • warning resolver: The draft resolver fields match the target in substance, but the resolutionRule omits the ledger’s explicit basis for the scheduled refresh date and the June 2026 reference computation.
  • info optional_suggestion: In the final reasoning, explicitly label the method as a persistence-plus-recent-monthly-trend model to satisfy the model-prior check cleanly.
  • info optional_suggestion: Tie the lower-tail facility-population scenario to the all-rows-with-both-fields-populated rule, since row inclusion can directly affect the national weighted ratio.
