To date, healthcare organizations need well-established knowledge to support care quality. Managers invest in motivating medical staff and associated healthcare stakeholders to share their respective knowledge. Additionally, they invest in advanced technology to facilitate sharing process. However, these efforts essentially raise classification and privacy concerns. Technology configuration that does not meet management process requirements may lead to managerial difficulties. In fact, information classification in healthcare systems should respect privacy, yet still be accessible. Using qualitative research, our paper proposes a novel ontological model that extends the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) with privacy dimension to enhance access to sensitive patient’s data.
