Digital Tools in UMLS Metathesaurus Knowledge Processing.

Clinical search engines development is actual task for medical informatics. The main issue in this area is to implement high-quality unstructured texts processing. Ontological interdisciplinary metathesaurus UMLS can be used to solve this problem. Currently, there is no unified method to relevant information aggregation from UMLS. In this research, we have presented the UMLS as graph model and performed the spot check of UMLS structure to identify basic problems. Then we created and integrated new graph metric in two created by us program modules for relevant knowledge aggregation from UMLS.

Experience of development of the national surgical interventions coding system in Russia.

The paper discusses development issues of surgical procedures coding systems for use at the national and international levels within the health information systems. The work was carried out using the Russian and foreign experiences, including international standard ISO/FDIS 1828:2012. The development system structure contains basic categories of medical entities (axes): surgical deed and surgical subdeed, objects, site and interventional equipment. Abdominal surgeries (528 procedures) were entered in the coding system database and structured according defined categories.
