Evidence-based medicine (EBM) plays an important and dominant role in promoting effective decision-making in the health system. This study was aimed to evaluate the EBM performance among health-care workers (HCWs) in hospitals in Iran.
In this study (a cross-sectional study), participants were 2800 HCWs in hospitals. A researcher-made questionnaire was designed, and judgments of 10 experts were used for the improvement of content validity. The reliability of the questionnaire was assessed by the test-retest method (α = 0.85). Data were analyzed using the descriptive statistics, -test, and one-way ANOVA, in SPSS.16 software.
Eventually, 1524 questionnaires were completed (response rate: 54.4%). The results of the study show that 62%of participants have not accessed scientific journals, 52% of them have difficulties using the Internet at work, guidelines were not reachable for 76% of them, and about 80% have not access to databases. About 39% of participants were not well informed about databases of EBM, and 15.8% of them were immensely knowledgeable about EBM terminology. The most important problems to increase HCWs information about EBM include research methodology- related problems, lack of resources and motivation, and coordination problems. The most prominent facilitators include: providing training courses in EBM and increased facilities. Only work experience showed a significant correlation with barriers and facilitators, and gender revealed a significant correlation with barriers ( < 0.05).
It seems that prioritizing the increased access to information resources and databases, considering the research skills of the HCWs, extending the opportunities and increasing the facilities such as workforce, equipment, physical environment, and accessibility can have a great impact on the improvement of the activities associated with EBM.
循证医学（EBM）在促进卫生系统有效决策方面发挥着重要且主导的作用。本研究旨在评估伊朗医院医护人员的循证医学实践表现。
在本研究（一项横断面研究）中，参与者为医院的2800名医护人员。设计了一份研究者自制的问卷，并采用10位专家的评判来提高内容效度。通过重测法评估问卷的信度（α = 0.85）。使用SPSS 16软件中的描述性统计、t检验和单因素方差分析对数据进行分析。
最终，完成了1524份问卷（回复率：54.4%）。研究结果表明，62%的参与者无法获取科学期刊，52%的人在工作中使用互联网有困难，76%的人无法获取指南，约80%的人无法访问数据库。约39%的参与者对循证医学数据库了解不足，15.8%的人对循证医学术语非常了解。增加医护人员循证医学信息的最重要问题包括与研究方法相关的问题、资源和动力不足以及协调问题。最突出的促进因素包括：提供循证医学培训课程和增加设施。只有工作经验与障碍和促进因素显示出显著相关性，性别与障碍显示出显著相关性（P < 0.05）。
似乎优先增加信息资源和数据库的获取，考虑医护人员的研究技能，扩大机会并增加如劳动力、设备、物理环境和可达性等设施，可能会对与循证医学相关活动的改善产生重大影响。
