The money
$ thousands · HCRIS cost-report basis · as filed, QA-gated
Ratios tell you how this hospital is doing. Statements tell you what kind of organization it is, and where the money comes from. Every figure below traces to a public cost-report filing, shown as filed. A ratio computes only when every input is reported in the filing (otherwise its cell states which input is Not reported in source); a year whose balance sheet does not reconcile is labeled, and its derived ratios read Astrelis calculation unavailable.

How it operates
quality & operational context · CMS public reporting
A 16-bed hospital running at 20% occupancy, where swing beds are 71% of the inpatient business, and 96% of patient revenue is outpatient.
The metrics this hospital type is judged on: care quality, patient experience, and scale. Each is labeled by provenance class and public source; descriptive context only, never a ranking or adequacy claim. Provenance labels: Reported value is copied from the named public source; Astrelis calculation is a formula applied to unchanged reported inputs, with the formula shown; Illustrative estimate is a benchmark gap, multiplier, or scenario — never a measurement.

Employment and labor income multipliers are from the National Center for Rural Health Works 2016 study of Critical Access Hospital economic impact (IMPLAN Type II, U.S. rural county populations); the economic-activity ratio is from the AHA national hospital economic activity report and describes U.S. hospitals as a whole; it is not a CAH-specific or county-specific figure. Applying any of these to an individual facility is an illustrative advocacy scenario, not a measurement: local capture depends on payroll residency, purchasing patterns, and county economic structure the sources do not observe. This facility is a critical access hospital, the NCRHW study population. Direct figures are reported values from the facility's HCRIS cost report. Want a defensible facility-specific figure?
