# 🏥 CCDA (Consolidated Clinical Document Architecture) 📄
The CCD is a document standard developed by Health Level Seven International (HL7) for the exchange of clinical information. 🔄 It is a universally accepted format for sharing clinical data across different electronic health record (EHR) systems. 🌐

## 📚 CCD Standard Templates 📋
The CCD standard includes templates for different types of clinical documents, like:
- 📤 Discharge summaries
- 🗒️ Progress notes
- 📄 Clinical summaries
These templates are based on existing document standards like the Continuity of Care Record (CCR). ✅
