Solution Overview & Operational Bottleneck
A patient-first healthcare operations blueprint designed around real clinical workflows. Unifies appointment booking, patient registration, encounter history, diagnostic attachments, and billing into a secure, role-restricted web application.
Reception coordinates phone appointments on paper, doctors search across fragmented physical folders, diagnostic labs issue disconnected PDFs, and administrative staff reconcile billing after the patient has left. The clinical issue is fragmented coordination—not clinical competence.
Target User Personas & Responsibilities
Independent Doctor / Specialist
Requires fast appointment scheduling, structured encounter notes, and prescription history.
Polyclinic / Day Clinic Director
Needs multi-doctor scheduling, reception queues, billing, and lab report tracking.
Small Hospital Department Head
Manages departmental bed allocations, nursing notes, and discharge summaries.
Patient & Family Guardian
Wants transparent booking, visit reminders, and access to verified discharge receipts.

Data Classification & Privacy Handling
| Data Class | Real-World Examples | Storage & Encryption Handling |
|---|---|---|
| Public | Clinic doctor profiles, consultation hours, services list | Publicly readable via CDN caching. |
| Confidential | Patient contact phone, booking timestamps, billing totals | Role-restricted to reception and billing staff. |
| Highly Sensitive (PHI) | Clinical encounter notes, diagnoses, prescriptions, lab scans | Strict least privilege, KMS encrypted at rest, access logged in audit trails. |
Defensible Security Controls & Safeguards
| Security Control | Target Protection | Implementation Status | Prerequisite / Evidence |
|---|---|---|---|
| Encounter-Level Authorization | Prevents unauthorized staff from reading medical records outside active duty. | Reference design | Verified via negative permission tests. |
| Clinical Data Masking in Logs | Ensures application telemetry does not expose patient names or health data. | Recommended control | Structured logging formatters with regex redactors. |
| Air-Gapped Backup Restoration Drill | Guarantees clinic database recoverability during ransomware or outage. | Requires provider configuration | Automated daily snapshots + tested restore runbook. |
| Client-Side Input Sanitization | Prevents XSS in patient note input fields. | Implemented in SDK | @zelvori/core/security escapeHtml & sanitizeUrl. |
External Ecosystem Integrations & Security Boundaries
| Service Provider | Integration Type | Integration Method | Security Boundary |
|---|---|---|---|
| Transactional SMS/WhatsApp Gateway | Messaging | REST API via HTTPS with signed API token | Never includes diagnostic labels or medication names in SMS body. |
| Diagnostic Lab Data Feeds | Medical Documents | Webhook receiver with HMAC-SHA256 signature validation | Attachments scanned for MIME type and stored in private bucket. |
| ABDM (Ayushman Bharat Digital Mission) | National Health ID | Standardized FHIR / ABDM API connector (Phase 3) | Requires government-accredited client sandbox approval. |

Definition of Done & Verifiable Acceptance Criteria
Deployment Host, Database Isolation & Maintenance
Managed cloud infrastructure (AWS / GCP / DigitalOcean) with dedicated VPC subnets.
PostgreSQL instance with row-level security per clinic branch; database-per-hospital for multi-tenant deployments.
Automated daily encrypted snapshots with 30-day point-in-time recovery (PITR).
Weekly security patch audits, monthly restore verification test, quarterly staff access review.
Project Risks, Mitigations & Ownership
Mitigation: All alerts are strictly advisory; doctors retain final clinical authority and must confirm prescription details.
Mitigation: Short session timeouts (15 mins) and quick one-click lock screen for consultation rooms.
Mitigation: Clear contractual disclosures that regulatory compliance requires clinical governance and legal review.
