Objective: The aim of this study was to determine the effect of knowledge management dimensions on the level of performance of nurses working in Ayatollah Rouhani Hospital in Babol. Methodology: After reviewing the subject literature, the proposed model was presented in four effective factors of knowledge management on the level of performance. Then, a questionnaire consisting of 25 questions was designed based on these factors, and after gaining assurance of its validity and reliability based on expert judgment and calculating the Cronbach alpha coefficient, 350 questionnaires were distributed among 350 nurses of Ayatollah Rouhani Hospital in Babol in 2017, which were selected by random sampling method. In order to test the fitting of the research model and study the relationship between its variables, structural equation modeling was used using Lisrel software. Findings: The scores obtained from nurses' productivity in the four dimensions of knowledge management (knowledge creation, knowledge sharing, knowledge application, and knowledge storage of services), independent t-test and independent variance analysis showed that there was no significant difference in any of the different levels of demographic variables including gender, marital status, education, work experience, employment status and organizational status (p>0.05). In contrast, the result of a single-sample t-test showed that the mean of the four dimensions was greater than 3 (p<0.05), and the result of the level of performance of the four dimensions of the mentioned dimensions had a reasonable likelihood. Conclusion: The results of this study showed that most of the nurses of this center believe that the quad size of knowledge management on the level of performance among hospital nurses, in addition to improving the quality of nurses' services, also reduces the cost of the hospital.
