In the present day, in the context of the toughening of global competition in the field of health care and the efforts that different countries of the world spend on improving the efficiency of the public sector of economy, the problems associated with determining the factors of competitiveness of healthcare organizations come to the forefront. The research conducted by the authors showed that assessing the competitiveness and development potential of medical companies with the Keigan-Vogel positioning map often gives incorrect results. The study showed that a significant part of errors (22-28%) is due to an incorrect evaluation of the quality and effectiveness of medical services, which necessitates a clear delineation of these concepts. The work shows how these indicators effect the competitiveness of organizations in the health sector and what happens if we do not distinguish between these two concepts.
