MD-Staff vs Medallion
Software your team runs against a service that runs it for you, and both handle oversight unusually well. MD-Staff is the incumbent platform: a four decade credentialing, privileging, and peer review system operated by a hospital's own medical staff office, deployed across a reported 2,000 facilities, Best in KLAS five years running, and the most candid in the category, stating plainly that AI does not make decisions. Medallion is an NCQA certified CVO that performs credentialing as a managed service, the only vendor here graded B on AI centrality, with the broadest lifecycle coverage, structural expert review at critical stages, and performance backed guarantees. Both earn an A on autonomy, MD-Staff through candour, Medallion through architecture. If your failure mode is equipping your own team with a proven platform, start with MD-Staff. If your failure mode is outsourcing credentialing to an accredited AI and specialist operation, start with Medallion.
- The clearest AI boundary in the category, graded A on autonomy: MD-Staff states plainly that AI does not make decisions, its Aiva engine gathering documents and running license and sanction checks while the professional reviews only flagged discrepancies, a candour posture rather than an automation claim.
- A complete, proven system of record run by the customer's own staff: credentialing, privileging, peer review, and committee tooling in place across a reported 2,000 facilities over four decades, named Best in KLAS five consecutive years.
- Range across organisation size, scaled explicitly from small community hospitals to large state health systems.
- The strongest AI posture in the group, graded B on AI centrality where MD-Staff grades C: Medallion's AI agents do the credentialing work as an accredited managed service, with the broadest lifecycle coverage, graded A on setting.
- Oversight designed as structure, also graded A on autonomy but earned differently: experts review critical stages before work advances and train the agents, and performance backed guarantees shift delivery risk, with a reported 250,000 administrative hours saved.
- An NCQA certified CVO that performs credentialing for you, where MD-Staff is a platform your own team operates.

The core distinction is who runs the operation. MD-Staff is software a medical staff office operates itself, and is explicitly not a CVO; Medallion is an NCQA certified CVO that performs credentialing as a managed service. Both earn an A on autonomy but from opposite directions, which is the most interesting thing here: MD-Staff by publishing the limit, AI does not make decisions, and Medallion by building expert review into the workflow structurally. Medallion grades higher on AI centrality, the only B in the group, and on setting breadth; MD-Staff counters with four decades of adoption and repeated Best in KLAS recognition, a customer satisfaction signal Medallion cannot match on tenure. Evidence is vendor reported on both, though Medallion's performance guarantees shift risk. Neither publishes pricing or model accuracy.
