No app. No download. Just the messenger patients already use.
Clinical surveillance that lives in your messenger.
Projo Health monitors patients in clinical studies and remote treatment, gathers feedback, and
delivers patient education — through WhatsApp, RCS, and SMS. Secure transfer of medical
information, without the install friction.

The problem
Patient monitoring breaks at the last mile.
Three things every clinical and remote-care team rebuilds from scratch — and why they shouldn't have to.
Patients never install your app.
Adoption dies at the app store. Projo reaches patients where they already are — WhatsApp, RCS, SMS — so studies enroll faster and remote programs stick.
Secure medical messaging is hard.
End-to-end delivery, audit trails, and identity binding across consumer messengers is a compliance minefield. Projo handles the channel, the consent, and the record.
Surveillance dashboards don't see the patient.
EHR and eCRF systems capture what clinicians type. Projo captures what the patient reports, in real time, and routes it back into your FHIR backend.
How it works
From QR scan to outcome in three steps.
No app store, no credentials, no training. The patient scans a QR code and lands in a preconfigured messenger conversation.
01
Clinician hands out a QR code
A clinician or study coordinator configures a protocol in Projo and hands the patient a QR code — printed, on a card, or on-screen. The code is bound to that protocol and that patient slot.
02
Patient scans and self-onboards
The patient scans the QR code with their phone camera. Their preferred messenger — WhatsApp, RCS, or SMS — opens a preconfigured conversation. No app to install, no account to create. Consent is captured in-thread.
03
Responses flow back to your FHIR backend
Scheduled check-ins, surveys, and educational nudges run automatically. Structured and free-text responses, adherence signals, and patient-reported outcomes are written back to Fire Arrow — auditable and ready for your eCRF or EHR.
Features
Everything you need to run a study in a messenger.
A complete surveillance layer for clinical studies, remote treatment, and patient engagement — without a patient-facing app.
Messenger-native channels
WhatsApp, RCS, and SMS out of the box. Patients join a study by scanning a QR code — no app to install, no account to create.
Secure medical transport
Identity binding, consent capture, and audit trails across consumer messengers. Built on Fire Arrow's FHIR-native authorization.
Scheduled surveillance
Recurring check-ins, PRO instruments, and reminders delivered on a CarePlan timeline. Automated, configurable, no-code.
Real-time monitoring
Responses, adherence signals, and deterioration flags stream back to your dashboard the moment a patient replies.
Patient education
Deliver protocol-aligned education, multimedia content, and nudges inline — in the same thread the patient is already in.
Feedback & engagement
Capture patient-reported outcomes, satisfaction, and free-text feedback without a separate survey tool.
Fire Arrow-native
Responses materialize as FHIR resources. Your eCRF, EHR, and analytics stack read from the same source of truth.
Zero-friction enrollment
Patients opt in with a single message. Drop-off between referral and first completed check-in falls dramatically.
Use cases
Built for the full patient-engagement loop.
From study enrollment to remote care, from feedback capture to education delivery — Projo runs the last mile.
Clinical study surveillance
Schedule PRO instruments, medication adherence checks, and adverse-event follow-ups across a study cohort — delivered through the messenger patients already use.
Remote patient monitoring
Check in with patients on a remote treatment pathway between visits. Catch deterioration early, reinforce adherence, and reduce avoidable readmissions.
Feedback & PRO collection
Capture patient-reported outcomes, satisfaction, and free-text feedback without a separate survey tool or a second patient login.
Patient education
Deliver protocol-aligned education, multimedia content, and behavioral nudges inline — in the same thread the patient already opens daily.
Patient engagement
Keep enrolled patients engaged across the full study or care duration. Scheduled nudges, two-way Q&A, and human handoff when a coordinator is needed.
Secure medical messaging
Transport medical information between patients and care teams with identity binding, consent capture, and full audit — no consumer chat app required.
Security & compliance
Secure medical messaging, by default.
Projo is the surveillance layer between the patient's messenger and your regulated backend. The channel is familiar; the controls are clinical.
Messenger identity & patient records
Projo maintains a 1:1 match between each patient's WhatsApp or RCS identity and their patient record. Patient identity itself can be captured through in-thread Questionnaires where the protocol requires it.
Consent capture & audit
Consent is captured, versioned, and auditable before any medical information flows. Every message, response, and state change is logged with a full audit trail on the Projo side.
Secure transport over consumer messengers
Medical information is transported through WhatsApp, RCS, and SMS with channel-appropriate safeguards and end-to-end audit on the Projo side.
Anonymization by default
Patient data is anonymized for research, analytics, and cross-cohort reporting. Identity filters and property filters strip attributable fields at query time, so blinded access is the default, not an add-on.
FHIR-native on Fire Arrow
Built on Fire Arrow Server — a FHIR backend developed under an ISO 27001-aligned QMS. Responses materialize as FHIR resources with the same authorization boundary as your EHR.
EU residency & default-deny access
Deployed in EU-resident infrastructure with default-deny authorization. RBAC, compartments, and anonymization filters are part of the deployment, not an afterthought.
Projo is built on Fire Arrow Server
and developed under an ISO 27001-aligned quality management system by Evoleen Technology GmbH.
