CCDA Validation & Ingestion Tool
Enterprise Clinical Informatics Engine
High-concurrency XML auditing and relational SQL Server ingestion engine for clinical documents with advanced encounter mapping and narrative normalization.
Business Problem
Clinical informatics teams struggled with inconsistent XML structures and 'dirty' narrative data in C-CDA documents, leading to unreliable longitudinal patient records.
Technical Challenges
Mapping complex, nested C-CDA XML to relational schemas while ensuring data fidelity across 60+ clinical sections and handling high-concurrency document ingestion.
Architecture
A multi-threaded XML processing engine designed for high-concurrency ingestion, utilizing a normalized SQL Server schema with advanced parent-child mapping for clinical encounters.
Implementation
Developed a custom C-CDA parser with advanced parent-child mapping for encounters and narrative table normalization to eliminate data noise. Integrated HIPAA-compliant PHI security protocols.
Scalability
Capable of auditing and ingesting large volumes of complex C-CDA documents with high performance using optimized multi-threading.
Results / Impact
Established a high-fidelity clinical data warehouse for population health analytics and improved identification of high-risk patients.
Lessons Learned
Relational mapping of clinical XML requires deep domain knowledge. Normalizing 'messy' narrative data early is key to downstream analytics accuracy.
