Dual Coding

Overview

Dual coding is a core feature of AyushBridge that enables healthcare systems to use both traditional medicine terminologies and modern biomedical classifications simultaneously. This approach ensures comprehensive documentation while maintaining interoperability with global health standards.

How Dual Coding Works

Dual coding allows healthcare providers to capture patient information using traditional medicine concepts while automatically mapping to equivalent biomedical terms. This creates a bridge between cultural healing practices and evidence-based medicine.

The Process

Primary Coding: Document using traditional medicine terminology (NAMASTE)
Automatic Mapping: System translates to biomedical equivalents (ICD-11)
Unified Storage: Both codes stored with confidence scores
Flexible Retrieval: Access information in either coding system

Mapping Quality

Each dual-coded entry includes:

Confidence Score: Indicates mapping reliability (0.0 to 1.0)
Mapping Type: Direct, related, or approximate
Source References: Links to terminology authorities

Supported Code Systems

Traditional Medicine Systems

NAMASTE: National AYUSH Morbidity & Standardized Terminologies Electronic
- Covers Ayurveda, Siddha, Unani, Yoga, Naturopathy, and Homeopathy
- 4,500+ standardized terms for disorders and conditions
WHO ICD-11 TM2: Traditional Medicine Module 2
- 529 disorder categories specific to traditional medicine
- Integrated with global ICD-11 classification

Biomedical Systems

ICD-11 MMS: Mortality and Morbidity Statistics
- Foundation component of ICD-11
- Used for statistical reporting and epidemiology
SNOMED CT: Systematized Nomenclature of Medicine Clinical Terms
- Comprehensive clinical terminology
- Supports detailed clinical documentation

Clinical Workflow

Diagnosis Entry: Clinician enters diagnosis in traditional terms
Automatic Translation: System suggests biomedical equivalents
Validation: Clinician reviews and confirms mappings
Storage: Both coding systems preserved in patient record
