A Coordinated Digital Platform for Home Hospitalization in Oncology
Including the integrated Toxicity Reader module
Functional Specifications Technical Specifications MVP
September 2026
Today's home hospitalization monitoring is fragmented, reactive, and burdensome.
Toxicity symptoms reported by phone may take hours or days to reach the oncologist. Grade 3+ events can escalate before clinical review.
PDF reports, phone logs, and paper forms scattered across multiple systems. No single view of patient status for the care team.
Nurses spend significant time on phone tag, manual transcription, and chasing missing information instead of patient care.
Make home hospitalization as safe as inpatient care through a single coordinated digital platform.
Home care with the same safety standards as hospital wards — structured monitoring, automated grading, and tiered alerting.
Single source of truth for all care team members — oncologists, nurses, GPs, pharmacists, patients, and caregivers.
Structured CTCAE-based monitoring catches toxicity at Grade 1-2 before it escalates to Grade 3+ emergencies.
Eight roles, each with a clear interface and responsibilities.
Treatment decisions, toxicity review, regimen management
Care coordination, alert triage, patient follow-up
Home visits, clinical observations, vital signs
Primary care integration, co-morbidity management
Medication review, interaction checks, dispensing
Self-reporting, questionnaire completion, view guidance
Assist patient, receive notifications, proxy reporting
User management, system configuration, audit review
CTCAE v5.0-based structured toxicity assessment with automated grading and tiered alerting.
Mobile-friendly questionnaire covering 5 CTCAE domains with immediate guidance.
Each symptom rated: Mild / Moderate / Severe / Life-threatening
At-a-glance overview of all active patients, alerts, and recent activity.
| Time | Patient | Alert | Grade | Action |
|---|---|---|---|---|
| 14:32 | Martin D. | Persistent nausea, unable to eat | Grade 2 | Review → |
| 13:15 | Dupont S. | Neutrophils 0.8 × 10⁹/L, fever 38.5°C | Grade 3 | Urgent → |
| 11:40 | Leroy A. | Mild fatigue, Grade 1 | Grade 1 | View → |
Chronological feed of all events, filterable by role and event type.
Each role sees events relevant to their scope. Patients see their own reports and guidance. Oncologists see all clinical events. Nurses see coordination events.
Automated escalation based on CTCAE grade with defined response times and protocols.
Recorded in timeline only.

Lightweight, portable, zero-dependency architecture designed for healthcare environments.
Healthcare IT environments are restrictive. No admin rights, no internet, no package managers. This architecture runs from a USB stick on any Windows machine.
Designed for the most restrictive healthcare IT environments.
Self-contained executable. Double-click to run. No installation, no registry, no DLLs.
Run directly from a USB drive. Take your system to any workstation. Data travels with you.
Zero privilege escalation. Runs in user space. Compatible with locked-down hospital PCs.
Replace the .exe to update. Database is separate and preserved. No migration scripts needed for MVP.
Windows 10 / 11 (primary). macOS and Linux builds possible with PyInstaller cross-compilation.
Healthcare-grade security built into every layer of the system.
Role-based access control (RBAC). 8 distinct roles with scoped permissions. Session timeout management.
Password hashing with scrypt. Secure session tokens. CSRF protection on all state-changing operations.
Immutable audit log of all actions. Who did what, when. Full traceability for clinical governance.
Content Security Policy (CSP) headers. XSS protection. Input validation and sanitization.
GDPR-ready data model. Patient data minimization. Right to erasure support. Data export capability.
Local-only by default. No data leaves the machine unless explicitly configured. HTTPS when networked.
Clearly defined scope with measurable deliverables.
Demo data included for immediate stakeholder testing.
From MVP to production in structured phases.
Working prototype with demo data. Stakeholder validation.
Clinical pilot with real patients. Feedback loop. Refinement.
Full deployment. Multi-site support. Monitoring and support.
