Evaluation and Challenges of Medical Procedure Data Harmonization to SNOMED-CT for Observational Research

Stud Health Technol Inform. 2022 May 25;294:405-406. doi: 10.3233/SHTI220484.

Abstract

The relevance of health data research on real world data (RWD) is increasing. To prepare national RWD for international research, harmonization with standard terminologies is required. In this paper, we evaluate to what extent the German OPS vocabulary in OHDSI covers codes present in RWD and mappings to SNOMED-CT. The evaluation identified a mapping gap of 21.1% in the RWD set.

Keywords: OHDSI; OMOP; OPS; SNOMED-CT; interoperability.
