How do CertifyOS and MD-Staff handle patient data?

Nothing says how long primary source verification files and supporting documents are kept, whether provider data is used to train or improve the matching and cleansing models, or whether anything is deidentified.
For MD-Staff, the scoping point comes first. What this platform holds is provider identity data: licenses, certifications, sanctions history, training, references and application documents.

Neither publishes a price or how its models are tested. CertifyOS's savings figures (75 percent lower recredentialing costs, 80 percent shorter credentialing) come with no baseline. Ask both for their verification error rate and how a wrong record is corrected.
