BACKGROUND: Improving patient safety is a global health imperative, and patient safety climate is one of the components one that plays an important role in promoting patient safety. Medical error reporting is a way through which it can be evaluated and prevented in the future. The aim of this study was to assess the relationship between patient safety climate and medical error reporting in military and civilian hospitals.METHODS: This research was conducted by using structural equation modeling in the selected hospitals of Iran in 2018. The study community consisted of 200 nurses in the military and 400 nurses in the civilian hospitals. By using Structural Equation Modeling, the relationship between patient safety climate and the rate of medical error reporting in the hospitals was measured by a questionnaire. Data was analyzed using SPSS 17 and LISREL 8.8 software.RESULTS: The mean score of patient safety climate was moderate in the hospitals. There was no significant relationship between the rate of medical error reporting and patient safety climate, while a significant difference was found between patient safety climate score and age, sex, job category, and type of hospital (P < 0.05).CONCLUSION: The results suggested that patient safety climate and the rate of reporting errors were not favorable in the studied hospitals, while there was a difference between safety climate dimensions.
