AI-native virtual care, FHIR backed and EHR synced

Widal partnered with a multi-state direct primary care network to ship an AI-native virtual care platform: FHIR-backed encounter capture, bidirectional EHR sync, RPM ingestion, and clinical workflow automation. Built as a brownfield overlay on the operator's existing stack, not a replatform.

The challenge

Virtual care that fits a working clinical operation.

  • 01

    Replace ad hoc telehealth and chart workflows with a unified encounter model, without disrupting existing clinician routines.

  • 02

    Sync structured encounter and observation data with the operator's existing EHR in both directions, with low latency.

  • 03

    Ingest real-world remote patient monitoring streams (BP cuffs, CGMs, scales) into the same clinical inbox, without flooding the team.

  • 04

    Automate the predictable parts of the workflow (intake, follow-up tasks, documentation) so the clinical team spends its time on the work that needs a human.

The solution

Encounter, sync, monitor, automate.

  • 01

    Designed the encounter and observation model around FHIR R4 resources, so EHR sync and downstream analytics share one shape of data.

  • 02

    Built bidirectional EHR sync against the operator's existing system with conflict resolution at the resource level.

  • 03

    Ingested RPM device streams into a per-patient state machine that flags meaningful change and ignores noise, integrated into the clinician inbox.

  • 04

    Layered an agentic workflow tier on top: documentation drafting, follow-up task generation, and intake summarization, with explicit clinician review gates.

  • 05

    Shipped HIPAA-aligned infra: segregated PHI, BAA-only vendors, audit logging on every state transition.

The impact

A working virtual care platform, in production.

  • 01

    Cut encounter cycle time across the operator's clinical team.

  • 02

    Unified telehealth, RPM, and asynchronous care into a single inbox and chart.

  • 03

    Removed manual chart double-entry between virtual encounters and the EHR of record.

  • 04

    Reduced documentation overhead on the clinical team by automating the predictable parts under clinician review.

A two-week architecture read, then a forward deployed pod for the build. We work the way the operator already measures.
