Patient Administration System

Orbis PAS UKI

A healthcare application widely used in UK and other European countries

Project Overview

Orbis PAS UKI is an enterprise-grade Patient Administration System (PAS) utilized by leading medical facilities across the UK and Continental Europe to streamline hospital administration, patient admissions, GP referrals, and medical case histories.

The Problem

European healthcare providers needed scalable, multi-jurisdictional compliance for administrative patient workflows, requiring seamless interoperability, zero downtime, and strict data protection adherence.

The Solution

Developed modular PAS web interfaces with Angular frontend and .NET backend, optimizing complex SQL queries for high database concurrency, while establishing high unit-test coverage using Karma and Jasmine.

Key Features & Modules

Patient Management: Comprehensive demographic records, insurance details, and admission histories.
Referral Tracking System: Automated processing of incoming medical referrals from primary care providers.
Medical Cases Engine: Multi-specialty case categorization, treatment plans, and medical history logging.
European Regulatory Compliance: Built to fulfill strict European healthcare privacy and regulatory standards.

System Architecture

  • Angular component architecture with strict TypeScript data interfaces.
  • Optimized SQL database stored procedures with complex multi-table joins & sub-queries.
  • Automated test suite using Karma and Jasmine for regression prevention.

Engineering Challenges & Solutions

Challenge: Executing heavy database operations over millions of historical patient records.
Resolution: Optimized relational SQL queries using indexed sub-queries, joins, and execution plan tuning.
Challenge: Ensuring multi-country healthcare regulatory compliance.
Resolution: Architected granular role-based access control and strict data validation layers.
