FHIR-first medical software backends have a narrower MPI engine shortlist than the broader MPI market. The engine has to expose Patient and $match natively, integrate with the FHIR server without translation glue, and support both determini

Medical software vendors picking an MPI face one architectural decision that shapes everything downstream: cloud or on-prem. Both models ship in production. The choice between them comes down to how the vendor wants to handle customer-speci

Healthcare IT vendors discover provider-patient overlap the hard way. A nurse practitioner who works at a clinic also becomes a patient at the same clinic; the MPI matches her clinician record to her patient record because the demographic d

Telemedicine vendors operating across multiple states carry a quiet identity problem. The same person legitimately appears with different Medicaid identifiers in different states, different last names after a marriage event, sometimes diffe

FHIR-first EMR vendors with engineering ownership of the identity layer have a narrower open-source MPI shortlist than the broader MPI market suggests. The tools have to speak FHIR fluently, expose Patient and $match natively, and not coupl

Telemedicine vendor backends rarely face a clean either-or between deterministic and probabilistic matching. The real question is which approach gets called first, which one handles the fall-through cases, and how the vendor surfaces match

Medical software vendors onboarding multi-tenant customers face an MPI selection problem that single-tenant vendors never see. The same person can legitimately appear in two customer tenants and the MPI must not merge them across tenants wi

Telemedicine vendors carry an unusual matching workload. Patients enroll over the phone or through an app, the demographic data they provide is whatever they happen to type, and the same person often appears across multiple states with subt

EHR and EMR vendors with FHIR-native backends face a narrower MPI selection problem than vendors retrofitting MPI onto legacy stacks. The MPI has to speak FHIR fluently, expose Patient resources and $match natively, and integrate with the F

A master patient index is the layer in any healthcare software stack that decides whether two records describe the same person. For a medical software vendor in 2026, the MPI choice shapes how the product handles customer onboarding, cross-
