Background: Professional nursing organizations play an important role in improving the image of nurses in the health care system, improving the quality of medical care, spreading best practices and scientific achievements in the field of nursing, reviving the traditions of nursing, protecting the interests of nurses in legislative, administrative and other bodies, and much more. Aims: The purpose of this study was to study the activities of regional associations of nurses to support the association in the National Association of Professional Nurses of the Republic of Kazakhstan, which will allow participation in the international community of nurses. Methods: This study used a qualitative research method. A thematic method was used for data analysis. Ten representatives of professional organizations took part in the study. Results: Respondents expressed the opinion that one of the advantages of the National Association is access to the international level. They wished that Nursing in Kazakhstan would not lag behind other developed countries, and the chairs of the national Association of nurses of Kazakhstan could protect the interests of nurses at the international level. In addition, the main advantage of national associations is to achieve interprofessional cooperation with other developed countries. Conclusions: Leaders and members of associations are highly motivated to create a new structure and membership in the International Council of Nurses. However, one of the main obstacles is the small number of members of regional associations and the lack of understanding by ordinary nurses of the advantages of membership in a particular Association.
