Data collection was carried by using the Persian version of HSOPS, developed by Agency for Healthcare Research and Quality (AHRQ). Cronbach's alpha and chi-square tests were employed in statistical analyses.
Results: Among the dimensions of patients' safety culture with the highest percentage of positive responses the teamwork within units (67%) was higher, whereas that with the lowest percentage of positive responses was non-punitive response to error (51%). Except to Handoffs and transitions dimension the entire dimension scores were lower than the benchmark scores. The study revealed that more than half of the participants were not reported the errors.

Results: Based on study technical efficiency in various scenarios were different. The results showed that health systems are high sensitive to human resources, and health sector's usually share the national expenditure difference scenarios during the period of study which show the managing efficiency and scale improvement s in Iranian health system.
Conclusion: This study showed the countries with the highest and lowest performance and efficient states (reference) for the inefficient countries among a few countries which increased their health resources to improve performance. However, with high efficient resource allocations in the most countries to achieve into these results are very significant to economic savings.
