Background: Organizational culture represents values, beliefs, hypotheses, norms, and goals, which are widely accepted in organizations. The existence of a culture suited to organizational goals in the organization leads to an increase in the efficiency and effectiveness of the organization. The present study aimed to determine the dimensions of organizational culture using the Denison Model and the related factors in the employees of the Gorgan health network in 2021.

Methods: The present research was a cross-sectional study. The statistical population of the present study included 188 employees, who were selected through a simple random sampling method from the provincial health deputy, city health center, comprehensive urban health service centers, and comprehensive rural health service centers. The Denison Organization Culture Survey was used to collect data. Descriptive statistics, Pearson's correlation coefficient, independent t-test, and one-way analysis of variance were used to analyze the data in the SPSS software and a significance level of 0.05.

Results: The total score of organizational culture was lower than the average value. Except in the team orientation dimension, where the mean scores were higher than the average value, the mean scores were lower than the average value in other dimensions of empowerment, capability development, core values, agreement, coherence and coordination, creating change, customer focus, organizational learning, strategic direction and intent, goals and objectives, and vision. The results showed a significant direct relationship between the number of children and the dimensions of empowerment (P-Value = 0.017), team orientation (P-Value = 0.020), and organizational learning (P-Value = 0.001).

Conclusion: Since the level of the organizational culture was lower than the average value, strengthening organizational culture in a scientific, practical, and applied way is necessary.
