Presentation Transcript

  1. What is HL7? A Brief Introduction to Healthcare Data Standards

  2. Introduction to HL7 • • HL7 (Health Level Seven) is a global standard for healthcare data exchange. • • Helps hospitals, labs, radiology, pharmacy and billing systems communicate. • • Ensures accurate, secure and structured flow of patient information.

  3. Why HL7 Matters • • Standardizes healthcare communication. • • Reduces data errors & mismatches. • • Enables interoperability between different systems. • • Improves workflow and patient care quality.

  4. Where HL7 is Used • • Hospitals & Clinics • • Laboratory Information Systems (LIS) • • Radiology (RIS/PACS) • • Pharmacy Systems • • Billing & Insurance • • Public Health Reporting

  5. Common HL7 Message Types • • ADT – Admission, Discharge, Transfer • • ORM – Order Entry • • ORU – Lab/Observation Results • • DFT – Billing Transactions • • SIU – Scheduling Information

  6. Benefits of HL7 • • Faster data exchange between systems. • • Reduces manual work. • • Minimizes errors. • • Supports digital transformation. • • Enhances overall healthcare efficiency.

  7. Conclusion • HL7 is the foundation of modern healthcare interoperability. • It ensures systems communicate smoothly and improves patient care. • Understanding HL7 opens doors to careers in Healthcare IT & Integration.
