Pennsylvania: the whole chain, end to end

One state traced all the way through: every active practitioner, whether the directory gives them an organization, whether that organization has a working address for software, and which vendor is behind it. Includes a county map you can zoom, and a named list of the organizations nothing public reaches.

230,837 practitioners. 43.7% have an organization at all. 18.7% reach an address software can use.

What CMS asked for, in element 2

“The metrics you will use to measure the effectiveness and progress of your PR strategy, including links to any public-facing data or reporting.”

Each state page below is one such public-facing artifact. The methodology and denominators are pre-registered before numbers populate; numbers are reproducible from a pinned NPD release with open analysis code under Apache-2.0. State agencies are welcome to cite these pages directly in their CMS response.

Each state page is a state-filtered re-run of the same six published findings, with state-specific MCO context and a citation block. If your state agency would like an audit slice prepared for your CMS response, email gene@fhiriq.com with the state code. Underlying methodology is open under Apache-2.0, so a state IT team can also run the analysis script directly: see analysis/state_findings.py.
