Zentro

Inspiration

Modern healthcare delivery is critically broken across two extremes. On one hand, patients are forced to juggle fragmented, disconnected tools—navigating separate portals for symptom checking, appointment scheduling, video consultations, and physical paper records. On the other hand, the tech industry's rush to apply generative AI to clinical triage has introduced a dangerous vulnerability: unbounded LLMs hallucinate, produce inaccurate dosages, and lack legal accountability.

In high-stakes healthcare, an AI model that is "95% accurate" is unacceptable a single hallucinated triage response can be fatal.

We built Zentro + Dawki to solve both problems simultaneously:

Unifying the fragmented care journey into a single, high-performance platform.
Eliminating AI hallucinations in clinical decisions by engineering a Deterministic Truth Engine, where mathematical clinical safety rulesets strictly overrule probabilistic AI guesses, backed by cryptographic auditability and human clinician supremacy.

What it does

Zentro is an end-to-end governed healthcare operations platform, powered by Dawki, an embedded deterministic intelligence layer. Instead of leaving clinical safety to chance, Zentro orchestrates 5 connected, production-ready live MVPs:

🩺 Deterministic Clinical Safety Triage (/dawki/fever):
- Guided, Fahrenheit-first patient intake collecting vitals, duration, progression, and emergency red flags.
- Evaluated in real time against versioned, clinic-approved deterministic rulesets (e.g., FEVER-EM-001, FEVER-URG-002).
- Routine cases unlock appointment booking; emergency cases immediately lock routine booking, display emergency instructions, and alert on-call clinicians.
- Zero AI hallucinations in triage decisions.
📅 Atomic Real-Time Scheduling (/appointments):
- High-concurrency appointment engine powered by a standalone Java Spring Boot service.
- Prevents double-booking collisions with atomic slot reservation locks and automated consent-aware confirmation pipelines.
📹 Virtual Doctor Telehealth (/telehealth):
- Direct browser-based virtual consultation rooms.
- Full lifecycle verification state tracking (requested → in_consultation → verified → needs_followup).
📁 Encrypted Health Document Locker (/health-records):
- Secure upload and management of prescriptions, CBC blood reports, and lipid profiles.
- Enforces byte-level MIME signature inspection (magic numbers like %PDF- and 0xFF 0xD8 0xFF), 10 MB file caps, filename sanitization, and HL7 FHIR R4 interoperability.
👩‍⚕️ Clinician Operations & Governance Queue (/clinician):
- Priority doctor review queue featuring real-time SLA countdown timers (<15 mins for urgent, <5 mins for emergency).
- Mandatory clinician override rationale logging: doctors have full authority to override, but every decision is committed to an immutable audit trail.
🤖 Governed Platform AI Assistant (/support):
- Allowlisted, cited navigation assistant equipped with prompt-injection defense (blocking jailbreaks, DAN modes, and system prompt leaks) and strict PII/PHI redaction.
