An entry generation pipeline for converting free-text medical document into Clinical Document Architecture document with entry-level

The Clinical Document Architecture (CDA) is a widely adopted international standard for clinical documents design; the CDA document with coded entries increases the semantic interoperability in the course of clinical document exchange. This study developed a CDA entry generation pipeline for converting free-text documents into CDA documents with entry-level. The results showed that CDA entry coding could be accomplished using natural language processing.
