About Willowbrook Health Data

Willowbrook Health Data turns public healthcare registries and de-identified claims into analysis-ready datasets for pharma, payers and health-tech companies. It works only with professional, trial, product and aggregated data, and never sells patient-level records.

Data sources and methods

Where the data comes from
CMS NPPES and provider enrolment files, state licensing boards, public clinical trial registries, FDA databases, CMS NADAC files, and claims from clearinghouse partners that are de-identified before Willowbrook receives them.
How it is collected
Weekly ingestion of public files, entity resolution across sources, and HIPAA expert-determination de-identification with small-cell suppression for all claims products.
What sets it apart
One provider ID that links NPI records, affiliations and trial sites; claims aggregates certified by an independent statistician.

Use cases

What the provider licenses its data for, and what it does not allow.

Intended uses

Healthcare professional targeting, trial site selection, market access, pricing analysis and health economics research.

Not allowed

Re-identifying patients, marketing to individual patients or consumers, and insurance or employment decisions about individuals.

DataStoa's acceptable use policy applies on top: no re-identification, discrimination, surveillance or sanctioned uses.

Compliance and security

Provider-reported. Ask for certificates or a data processing agreement before you sign.

    Claims aggregates work well for market sizing

    Procedure volumes by region gave us a defensible market size for a new device. Small cells are suppressed, so rare procedures in small regions come back empty, which is the correct trade-off for de-identified data.

    Affiliation data is the strongest part

    Provider-to-hospital and group-practice affiliations were more current than our previous source, which improved territory alignment. Price is at the high end, so we licensed the national file without the API.
