Nexus Docs

Nexus is a hospital information system (HIS) covering the full clinical and administrative surface of a hospital — admissions, ward and specialty boards (ICU, Maternity, Emergency, Operations), laboratory and radiology (with FHIR R5 and LIS/DICOM integration), pharmacy, finance, HR, and reporting.

Stack

Layer	Technology
Backend	Go (module `hospital-management`), chi router, PostgreSQL
Frontend	Lit 3 web components, Vite, TypeScript
Interop	FHIR R5 resource mapping, LIS (MLLP) and DICOM device integration
Auth	JWT-based sessions with role-based access control (RBAC)
i18n	Full RTL/LTR support (Arabic and English) via logical CSS properties

Layout

backend/internal/ — domain packages: auth, fhir, lis, orchestrator, specialty, notify, storage, and per-feature handlers.
frontend/src/pages/ — one Lit page component per module (wards, lab, pharmacy, radiology, finance, HR, and the specialty kiosks).
frontend/docs/ — the department-level guides, split here into a User Guide (business-level walkthrough for staff) and Technical Guides (routes/RBAC/API reference for engineers).

Design language

Nexus uses a deep-teal palette (clinical without being cold) with a warm clay accent reserved for people — patient identity and care-team attribution never share a color with system chrome or status indicators. This documentation site is themed with the same tokens; see frontend/src/styles/theme.js for the full palette and rationale.

User Guide

What each kiosk is for and how staff use it day to day — no technical detail.

ICU The first of the four specialty boards — critical-care patient chart, vitals, and orders. Maternity Labour, postpartum, and newborn care board — the second specialty kiosk. Emergency ER triage, boarding, and disposition — the third specialty kiosk. Operations OR / surgical ward board — the fourth and last specialty kiosk. Ward General inpatient stays, elective admissions, and post-transfer recovery — the fifth and last ward kiosk. Laboratory OpenELIS-style lab workbench with patient-context popups — the sixth kiosk. Pharmacy Prescriptions, drug-safety, dispensing, counselling, and multi-pharmacy stock — the seventh kiosk. Radiology Imaging-studies queue with patient-context for contrast safety — the second non-bedside kiosk. Finance 21 tabs across 8 enterprise sections — receivables, payables, banking, and reporting. HR Role-based kiosk for HR management — independent of hospital department.
