Objective: Identify challenges in the applicability of ontological models that represent relationships and elements of health management competencies. Methods: Scoping Review, according to Joanna Briggs Institute (JBI) and the guiding question: “What are the challenges in the applicability of ontological models that represent the health management competencies described in health in the literature?”. Included national and international studies, English, Portuguese and Spanish, in the time span of 2015 to 2020. Results: The search strategy was applied in eight databases; 2024 articles were found and eight were selected as the final sample. The studies highlighted the following difficulties in this theoretical framework: interpretation of complex, heterogeneous and dispersed data by health managers, lack of automation in patient monitoring, lack of training of health managers, inadequate task distribution and workload of the nursing team and also, deficiency in decision-making shared between health professionals and the patient. Conclusions: The application of ontological models in health management systems resulted in time optimization, data integration and better management decision-making in order to positively help the work of health professionals and managers.
