Complex Referral Packets Were Delaying Patient Processing

Each home health referral could contain multiple documents with different layouts, formats, and levels of readability. Staff had to examine every file, locate relevant information, and manually transfer the data into internal systems before the referral could move forward.

• Reduce manual transcription across home health referral workflows.
• Process PDFs, scanned records, clinical notes, and diagnostic reports.
• Recognize handwritten prescriptions, annotations, and checkboxes.
• Extract consistent data from documents with different structures.
• Handle bulk referral uploads during periods of high demand.
• Maintain traceable, secure, and HIPAA-aligned document workflows.

From Manual Referral Intake to Structured Patient Data

Referral Workflow Discovery

We mapped the complete home health referral intake process, including document receipt, classification, data entry, validation, exception handling, storage, and transfer into downstream patient workflows. This identified the information that needed to be extracted from each document type.

Referral Data Schema Design

Structured data schemas were created for the clinical, insurance, patient, and referral information found across different document formats. This gave the LLM a consistent framework for converting unstructured medical content into usable records.

OCR and LLM Pipeline Development

We connected Google Cloud Vision API with an LLM extraction layer to create an end-to-end document intelligence workflow. OCR converts document images into readable text, while the LLM interprets, categorizes, and structures the extracted information.

Validation, Security and Quality Assurance

Automated validation checks extracted fields before they enter downstream workflows. Testing covered OCR accuracy, handwriting recognition, checkbox detection, LLM extraction, bulk uploads, concurrent processing, document versioning, and exception handling.

Cloud Deployment and Performance Optimisation

The platform was deployed using scalable cloud infrastructure designed for high-volume referral processing. Performance monitoring and workflow optimisation enabled the system to process more than 500 documents per hour while maintaining 99.9% uptime.

Referral Documents Converted Into Actionable Data in Minutes

Home health referral documents that previously required two to three hours to process can now be handled in under five minutes. NEXUS reduced manual data entry by 95%, allowing staff to spend less time transcribing documents and more time reviewing referrals and supporting patient care.

The system processes more than 500 documents per hour during peak periods and handles over 50 documents concurrently. Its automated validation workflow successfully verifies 98% of extracted data, while uncertain or incomplete information can be directed to staff for review.

By reducing data errors by 80% and operational costs by 70%, NEXUS gives the organization a faster and more consistent way to manage increasing referral volumes. Encrypted storage, document versioning, and traceable processing records support HIPAA-aligned workflows, audit visibility, and zero data loss.
