# Atlas Commons research objects — the national distribution of "Patients whose home-health care began in a timely manner"

The national distribution of "Patients whose home-health care began in a timely manner" across 8,640 U.S. home-health agencies, with each figure's status labeled: each per-agency rate is a CMS-measured OASIS outcome; the cross-agency distribution statistics (median 97.85%, p10 82.49% to p90 100%) are an in-house aggregation over the public panel, which CMS does not publish; the boundary is context — the national picture, not a per-agency verdict or a personal prediction.

## Claims

### "Patients whose home-health care began in a timely manner" is a CMS-measured home-health outcome, reported by 8,640 agencies

**RECORDED.** Patients whose home-health care began in a timely manner is a measured outcome rate (from OASIS patient assessments at admission and discharge) that 8,640 U.S. home-health agencies report to CMS. It captures how often patients actually start care without delay — an outcome (a change in the patient), not an input or a rating.

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Falsifier: A RECORD of measured/reported events (occurred=true) from CMS Home Health Care Compare; superseded when CMS Home Health Care Compare publishes its next release.

### Nationally, the median agency's "Patients whose home-health care began in a timely manner" rate is 97.85% (middle half 92.79–99.6%, p10 82.49% to p90 100%)

**DERIVED.** Across the 8,640 reporting agencies: median 97.85%, mean 93.98%, range from p10 82.49% to p90 100%. The per-agency rates are CMS-RECORDED; these DISTRIBUTION statistics are an in-house aggregation over the public panel — CMS does not publish the cross-agency distribution. They show where any given agency falls on the national curve.

Falsifier: occurred=FALSE (a calculation, not an event) and adjudged=FALSE (a transparent in-house formula, not an authority's verdict — no external adjudicator). Reproduce it from its named inputs; falsified if the formula or inputs are wrong. Lower warrant than the adjudged figures above.

### What this distribution is — and is NOT (the epistemic boundary)

**INTERPRETATION.** This is the NATIONAL picture of one outcome across all agencies — useful for seeing where a provider falls on the curve, and for understanding what "good" looks like. It is NOT a rating of any single agency (see that agency's page), NOT a prediction of how YOU or your relative will do (your clinician knows your case), and NOT a substitute for CMS Care Compare. The spread is real: choosing well moves a patient across a wide distribution of measured recovery.

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 measure (recorded) and the distribution stats (derived) above are grounded; this is the only interpretation, and the four-status says so.

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/outcomes/timely-start.jsonld`
