Healthcare Interoperability Tools

A collection of healthcare data interoperability tools developed during my Health Informatics internship at MIHIN (Michigan Health Information Network). This repository contains utilities for processing HL7 V2 messages and CCD (Continuity of Care Document) data mapping.

🏥 About

This project demonstrates practical applications of healthcare data standards and interoperability protocols, focusing on:

• HL7 V2 message parsing and validation
• CCD/C-CDA document data extraction
• Healthcare data mapping and transformation

🛠️ Tools & Technologies

• Python: Primary development language
• HL7 Library: For HL7 V2 message processing
• XPath: For CCD/XML document parsing
• Healthcare Standards: HL7 V2, C-CDA, FHIR concepts

🚀 Getting Started

Prerequisites

• Python 3.7+
• pip package manager

Installation

1. Clone the repository:

git clone https://github.com/DeepishkaPemmasani/healthcare-interoperability-tools.git
cd healthcare-interoperability-tools

2. Install dependencies:

pip install -r requirements.txt

Usage

HL7 V2 OBX Segment Parser

from hl7_tools.hl7_obx_parser import check_obx_subsegments

# Parse HL7 message for specific OBX subsegments
results = check_obx_subsegments(your_hl7_message)
print(results)

CCD Data Mapping

Refer to ccd-tools/ccd_mapping_guide.md for comprehensive XPath patterns for extracting data from CCD documents.

📚 Documentation

• HL7 V2 Message Processing
• CCD Data Mapping Guide

🔍 Features

HL7 V2 Tools
