Introduction
Patient safety is an essential part of high-quality health care. In developed countries, the average damage to patients caused by medical errors is estimated at 10-16% in inpatient departments and 15-21% in special care units, such that the overall risk of human casualties in medical centers is slightly higher than road traffic-related death rate and about 1000 times more than the death cases caused by chemical, nuclear or air population. Although medical errors are considered human errors, people cannot tolerate the errors from the medical community, because, regardless of the non-observance of ethical and human principles involved in providing safe care, the cost of these medical errors accounts for 5-10% of the total care costs. It can lead to longer duration of hospital stay, resulting in the risk of hospital infections, disability, and increased patient complaints. Therefore, patient safety is one of the controversial topics in the field of health care and is very important in various fields of nursing, including education and clinical practice. 
Based on the studies, there is a positive relationship between high perceived organizational support and positive nursing practice, which is reflected in their good work performance, job satisfaction, and innovative behaviors, and leads to patient satisfaction. It seems that if nurses perceive the support of the organization where they work and feel that they are accepted by the organization, they will be motivated to dedicate themselves to work and care about the progress of the organization, ignore other job opportunities, and try to continue working in their current position. This study aims to determine the relationship between safe nursing care and perceived organizational support in nurses working in the intensive care units (ICUs) of selected hospitals in Tabriz, Iran.

Methods
 This is a descriptive-correlational study with a cross-sectional design that was conducted in 2021-2022. The study population consists of all nurses working in ICUs of hospitals affiliated to Tabriz University of Medical Sciences. The data collection tool were a demographic form, Eisenberger et al.’s [32] perceived organizational support scale, and Rashvand et al.’s [35] safe nursing care questionnaire. After obtaining the code of ethics and a written informed consent from the participants, necessary arrangements were made on different days and hours of the week (morning, evening, night work shifts) for data collection. The questionnaires took 15 minutes to complete. Data analysis was done in SPSS software version 16 using descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistics (independent t-test, analysis of variance, and Pearson correlation test). P<0.05 was considered statistically significant.

Result
In this study, 200 nurses with a mean age of 33.34 ± 6.71 years participated, most of them were female (80%), married (60.5%), with permanent employment (64%) and insufficient income (69.5%). The mean score of the perceived organizational support was 23.2±9.57, which is lower than the cutoff point. The mean score of safe nursing care was 322.89±34.1, which is higher than the cutoff point, indicating a desirable level. The perceived organizational support had no statistically significant correlation with safe nursing care and its dimensions.

Conclusion 
Although the perception of higher organizational support in ICU nurses seems to be associated with safe nursing care, the results of the present study showed that, despite the unfavorable perceived organizational support of the nurses, the safe nursing care was at a favorable level. This finding is probably due to the professionalism of nurses and considering the nursing ethics, as well as the moral ethics. There may be influencing factors not considered in this study, including personal characteristics of nurses such as self-confidence, optimism, hope and flexibility, personal motivation and lack of other career options. Investigation of these factors in future studies may provide better insight into the study topic.
