Section 01

RxEngine AI Core Overview: A Multi-Agent-Based Clinical Prescription Decision Support System

RxEngine AI is an innovative Clinical Decision Support System (CDSS) designed to address patient safety risks caused by prescription errors and drug-drug interactions (DDI). Through LangGraph multi-agent orchestration and Groq Vision visual technology, it enables an end-to-end workflow from prescription image recognition to drug interaction detection and automated clinical analysis. Its core value lies in transforming traditional manual prescription review into a structured intelligent process, improving clinical efficiency and medication safety.

Project Background: Challenges and Needs in Prescription Safety

In the development of medical informatization, prescription errors and drug interactions remain important factors threatening patient safety. Traditional prescription review relies on manual experience, which is inefficient and error-prone. RxEngine AI emerged to address this: by combining computer vision, natural language processing, and knowledge graph technologies, it automates and structures the review process, completing full-process analysis in seconds to meet clinical needs.

Technical Architecture and Core Methods

Multi-Agent Workflow

The system uses a LangGraph-driven multi-agent framework, decomposing tasks into collaborative work by specialized agents:

  • Prescription Parsing Agent: Processes handwritten/printed prescription images and extracts structured drug information;
  • Clinical Reasoning Agent: Evaluates indication matching, dosage rationality, and contraindications;
  • DDI Detection Agent: Queries pharmacological knowledge bases to identify harmful drug combinations;
  • Report Generation Agent: Integrates results into structured clinical summaries.

Intelligent OCR Strategy

  • Groq Vision API: Main engine, handles complex layouts and handwritten prescriptions with low latency;
  • PyTesseract: Supplementary solution to improve recognition accuracy for standard printed text.

DDI Detection Mechanism

Screening at three levels:

  1. Pharmacological level: Identifies metabolic pathway conflicts (e.g., CYP450 enzyme system-related);
  2. Clinical level: Marks conflicting treatment goals or overly strong synergistic effects;
  3. Dosage level: Calculates cumulative dosage and detects plans exceeding safe ranges.

Technology Stack and System Architecture

Frontend Technology Stack

React 19 + TypeScript + Vite, Tailwind CSS for styling, Framer Motion for animations, Axios for communication, Lucide React for icons.

Backend Technology Stack

FastAPI asynchronous web framework, Motor for asynchronous MongoDB interaction, JWT+Bcrypt for identity authentication.

AI/ML Layer

LangChain + LangGraph to build multi-agent workflows, Groq SDK to access LPU inference services.

Data Layer

MongoDB Atlas cloud-native NoSQL database, storing patient records, prescription history, and system configurations.

User Experience and Deployment Process

Clinical Dashboard Features

  • Real-time analysis view: Displays OCR results and AI conclusions immediately after prescription upload, with risk items highlighted;
  • Patient history timeline: Visualizes medication history and analysis records, supporting longitudinal tracking;
  • Multi-role permissions: Distinguishes between doctors and administrators, with fine-grained access control;
  • Mobile adaptation: Responsive design, suitable for mobile scenarios like ward rounds.

Deployment and Usage

Environment requirements: Node.js18+, Python3.10+, MongoDB Atlas account. Configuration: Set environment variables such as Groq API key, MongoDB connection string, JWT secret. Demo account: doctor@rxengine.com / password. Usage flow: Upload prescription image → System automatically performs multi-agent analysis → Returns a report with risk prompts in seconds.

Section 06

Clinical Significance and Future Outlook

Clinical Significance

RxEngine AI combines large model reasoning with multi-agent workflows to achieve high accuracy and clinical-level response speed. It can effectively reduce prescription error rates, lighten the burden of pharmacist review, and is especially suitable for scenarios with tight primary medical resources.

Future Directions

  • Deep integration with hospital HIS systems;
  • Support for prescription recognition in more languages;
  • Continuous model optimization based on real-world data;
  • Extension to personalized medication recommendation capabilities.
