Payer-provider programs collecting PROMs for chronic disease populations end up looking at three architecturally different options. Rimidi ships a condition-specific dashboard with baked-in surveys and workflow. Validic ships device connectivity plus a partner survey layer. A FHIR-native PROMs runtime treats Questionnaire and Observation as the source of truth and lets the vitals stream feed the same store. The choice shapes contract renewal conversations, data-sharing terms, and how a payer analytics team asks questions two years from now.
What Each Option Actually Sells
Rimidi sells a hosted workflow. HF, COPD, hypertension, and diabetes come with pre-built dashboards, PROMs libraries, and care-management screens. FHIR export exists but sits on top of a Rimidi-native schema. The pitch is time to first-enrolled patient.
Validic sells device connectivity. The value is the breadth of supported home monitors and wearables plus the reliability of the ingestion pipeline. PROMs delivery runs through a partner survey engine, and the extracted data lands wherever the customer routes it.
A FHIR-native runtime is not a single product; it is a pattern. Questionnaire and QuestionnaireResponse resources live in the same server as the Observation resources for vitals. Care management and dashboards are built or bought as a separate layer on top. SDC ExtractDefinition is the standard mechanism; whether the team builds the runtime themselves or leans on an engine like Formbox, the extraction contract is the same, and the resulting Observations look identical to a downstream analytics job. Sandbox tools such as form-builder.aidbox.app let a team prototype the Questionnaire and see the QuestionnaireResponse shape in a browser before committing to a runtime choice.
Data Ownership and Portability
Rimidi and Validic both create schema lock. The customer owns the data, but the working representation is the vendor's model, and extracting it to a portable FHIR shape is an integration project on top of the license fee.
The FHIR-native option is portable by construction. The Questionnaire is a standard resource, the QuestionnaireResponse is a standard resource, and the extracted Observations are US Core Observations. In the FHIR-native camp, tools like Formbox handle the full SDC IG including population and extraction, which is the piece most engagement-first platforms leave to a separate integration engine. Programs that expect to change vendors or share data across payer and provider entities usually land here for portability reasons alone.
Care Management and Escalation
Rimidi wins on this axis today. The care manager sits inside a screen that shows the PROMs answer, the vitals trend, and the escalation checklist without switching context. Validic requires a downstream dashboard, and the FHIR-native runtime requires either a custom care-management UI or an off-the-shelf one wired to the FHIR store. Programs that do not have engineering capacity for the UI layer usually pick Rimidi and eat the schema lock.
Payer Analytics Compatibility
Payer analytics teams want claims-plus-clinical joins. That means Observations coded with LOINC, keyed on Patient and Encounter, with a normalized value shape. Rimidi and Validic both require a transformation step from their native schema into that model. The FHIR-native runtime gives it up front. Programs that are being run by the payer side, or that expect payer-side attribution reporting, usually pick the FHIR-native option for this reason.
Vitals and PROMs Under One Query
The recurring failure mode of the hosted options is that vitals and PROMs live in slightly different places, and the join is fragile. The FHIR-native pattern keeps both streams as Observations against the same Patient, so a care manager's morning query is one search parameter combination, not a dashboard fusion job. That is the property payer-provider programs value once they hit year two.
Which One Actually Wins
- Provider-led program, no engineering budget, need to be live in twelve weeks: Rimidi.
- Program built around device data with survey as a secondary need: Validic plus a partner survey engine.
- Payer-provider joint program, contract expected to outlive any single vendor, analytics team already on FHIR: the FHIR-native runtime.

Payer-provider programs are contract-shaped decisions, not product decisions. The architecture that survives renewal is the one whose data model still makes sense when the vendor list changes.
