We performed semi-structured in-depth interviews with 23 participants who were selected using purposeful sampling and were asked to describe the factors affecting the organizational position of nurse consultant. Results: The mean (standard deviation) age of the participants was 44.5 years (10.68). 279 meaning units, 39 codes, 6 subcategories and two categories were obtained in this essay. The two main categories include necessity for nursing consultation role with two subcategories (nursing consultation role as one of the main roles in nursing, and the need for nursing consultation in healthcare system in Iran), and the obstacles of nursing consultation role with four subcategories (healthcare system problems, problems associated with physicians, problems associated with nurses and problems associated with patients' culture). Conclusions: Considering the importance of nursing consultation role in improving the health of the patients, the policymakers should take into account the consultant role of nurses and they should understand the importance of and the need for this role.
