The total point of the patient safety culture in the majority of the hospitals were at a mean level of 3. The maximum score was 5. The maximum and minimum mean points were obtained by the Hasheminejad and Sina hospitals respectively. The results of the multivariate decision-making analysis indicated that human, managerial, organizational, and environmental factors were at the top of priorities in a descending order. The factors were extremely effective in the improvement of safety in hospitals.Conclusion:Human factors were the most effective and important factors in the improvement of safety in emergency wards.
