Composite quality score

Continuously-asserted accuracy of Fonteum's federal data layer.

Across 5 federal sources, snapshot 2026-05-26. A weighted mean of source-level completeness, inter-source consistency, ingestion lag, and the OIG LEIE byte-level match rate. Recomputed hourly; the machine-readable twin lives at /quality.json.

Methodology

How we score

The composite is a weighted mean of four sub-metrics — completeness, consistency, match rate, and timeliness. Versioned, peer-reviewable, snapshot-anchored.

Section 1

Per-source completeness

For each source, the median proportion of public-displayable required fields that are non-null and non-empty across rows in the latest snapshot. Snapshots over 100k rows are sampled to 10k uniformly — see methodology.

Source familyLast snapshotRow countMedian field completeness
NPPES (NPI registry)7.8M99.1%
OIG LEIE exclusions68K99.8%
CMS PECOS PPEF2.5M97.4%
Section 2

Inter-source consistency

Where two independent federal feeds describe the same NPI, do they agree? Each rate is the share of NPIs whose normalized value matches across both sources. The denominator is the set of NPIs present in both snapshots with a non-null value on each side.

  • Specialty agreement: NPPES taxonomy ↔ PECOS enrollment

    94.2% agreement · denominator 1.8M NPIs

  • Active-status agreement: NPPES ↔ PECOS

    96.1% agreement · denominator 2.1M NPIs

Section 3

Temporal update lag

Wall-clock hours between an upstream publication and Fonteum ingesting it. Computed over the trailing 90 days; the p95 number is the worst-case ninety-fifth percentile, not a synthetic SLA.

OIG LEIE byte-level match rate

Fonteum's archived copy of the OIG LEIE CSV matched the SHA256 OIG publishes alongside the file in 51 of the last 52 weekly snapshots — a 98.1% byte-level agreement.
