Abstract
Evidence-based medicine (EBM) is defining proper and wise use of the best evidence in clinical decision for patient׳s care. This study have done with the aim of evaluating health information system for decision-making with EBM approach in educational hospital of Kermanshah city. The statistical population include all the specialist and specialty, and also head nurses of educational hospitals in Kermanshah city. The data collected by researcher made questionnaire. The content validities of the questionnaire were confirmed by experts to complete the questions of the questionnaire. Then, the reliability of the questionnaire was evaluated using the Cronbach׳s alpha coefficient. The results have showed that the accessibility rate to the internet sources is in desirable level. The results have showed that there was a significant difference at least in one group between the availability of hospital information system EBM establishment in terms of accessing to the internet based data, according to the academic major (P = 0.021). The sufficiency of hospital information system in evidence-based medicine establishment in terms of necessary knowledge for implementing it according to the educational major have showed a significant statistical difference at least in one group (P = 0.001). Kermanshah׳s hospital have a desirable condition in terms of accessibility to the internet sources, knowledge of EBM and its implementation which this have showed the availability of desirable platform for decision-making with the EBM approach. However, it is better to implement regulate educational periods for educating the doctors and nurses in order to reach practical implementation of the EBM approach.

Value of the data
-
•
Evidence-based medicine (EBM) is defining proper and wise use of the best evidence in clinical decision for patient׳s care [1], [2], [3]. In fact, evidence-based medicine is a combination of the best evidence, which obtained from the researches of clinical experiences and patient׳s desire [4], [5] and use of the best evidences is its highest benefits [6].
-
•
One of the important cases in clinical decision were evaluation and critical judgment of observation and improper use of evidence could have led to patient׳s death. Therefore, it is necessary that the doctors could search and retrieve their proper evidence and combine it with their experiences and applied it for their patients.
-
•
Various studies have showed that the doctors have low knowledge of EBM and do not have the necessary skills for applying this method. While the knowledge and skills, which have related to EBM, were the important factors of using this process [1], [7], [8], [9]. Also it have presented that the Iran hospital information system do not have enough pieces for accessing to the health information based on the internet and reference database.
-
•
According to the above points and the necessity of knowledge about EBM, also applying it in treatment and care process, this study have done with the aim of evaluating the health information system for decision-making with EBM approach in educational hospitals of Kermanshah city.
-
•
This is the first study in Kermanshah, and its data can be useful for decision making. In addition, the present study data can be useful for future similar studies in other locations of Iran.
-
•
Based on the obtained data of this study, the Kermanshah hospitals have proper status in terms of internet resources accessibility, having proper awareness about EBM and its implementation.

For evaluating the sufficiency of hospital information system in establishment of EBM in terms of accessing the internet-based health information, according to the academic major, for normality of data distribution, the Lon test results have showed that the data have normal distribution (P > 0.05). Based on this fact the ANOVA test result have showed that at least in one group there was a significant difference between the sufficiency of hospital information system in establishment of EBM in terms of accessing the internet based health information due to the academic major (P = 0.02) (Table 5). For evaluating the fact that which majors are different, the Bonferroni post-hoc test have used and the results of this test have showed that there was a significant difference between the specialist of cardio vascular disease with head nurse, and infectious specialist with cardiovascular specialist.

For evaluating the sufficiency of hospital information system and establishment of EBM in terms of necessary knowledge for its implementation, according to the academic major, the Lon test results have showed that variances were homogenous (P > 0.05). based on the ANOVA of the academic major and the system sufficiency in terms of knowledge and EBM implementation there was a statistical significant difference at least in one group (P < 0.001) (Table 6).

| Accessing internet resources | 0.18 | 0.071 | .943 |
| Having the knowledge of evidence-based medicine and its implementing | 1.69 | 1.52 | 0.131 |
Based on the Bonferroni post-hoc test there was a significant statistical difference between the internal and cardiovascular specialist, internal and gynecologist specialist, cardiovascular and head nurses, internal specialist and other academic majors.
For evaluating the sufficiency of the hospital information system in establishment of EBM in terms of accessing the internet health information and having necessary knowledge for implementing EBM, according to the gender, first the variances equality have investigated and they were equal. Then the t-test results have showed that there was not any significant statistical difference between the men and women participants of the research (P > 0.05).
2. Study design, materials and methods
This study have done with descriptive cross-sectional method in 2017. All the specialist, specialty and head nurses of various parts in affiliated hospital to the Kermanshah University of Medical Science (KUMS) have included the statistical population. Sampling of this research have done with random sharing method. At the beginning of the study the number of specialist and nurses of various parts of educational hospitals in Kermanshah city have estimated and after that with the proportion of the statistical population and statistical samples each hospital take a share of them randomly. By using the krejcie-morgan table, the samples volume have calculated. By using the questionnaire, the data have collected. The content validities of the questionnaire were confirmed by experts to complete the questions of the questionnaire. Then, the reliability of the questionnaire was evaluated using the Cronbach׳s alpha coefficient [10], [12], [13], [14], [15], [16]. The formal and content validity of this questionnaire have validated by the experts of the medical and care information management major, which have some expertise in the field of EBM and some related experts with implementing EBM in Imam Reza educational hospital of Kermanshah. The reliability of the questionnaire have estimated by the internal consistency coefficient also the cronbach׳s alpha have calculated 0.81 The first part of the questionnaire have related to demographic properties of the participants. The second part includes 24 questions, which classified in four parts. 20 questions have presented in 5 Likert range (always=5 to very low=1) and 4 other question in 5 Likert range (very high=5 to very low=1). The designed questionnaire have distributed among all the study׳s sample and all the affiliated hospitals to KUMS and they have asked to answer the questions.
At the end the collected data of the questionnaire have enter the SPSS.ver21 software and by using the descriptive statistic (the frequency, mean and standard deviation) the descriptive tables have presented. Also after evaluating the normality by Kolmogorov Smirnov Test, the t-test used for comparison of the means with the hypothesis means. Also for comparison of demographic properties of responders based on the study׳s aims, for data normal distribution, the ANOVA parametric test and for non-normal, the non-parametric Kruskal-Wallis test (at significance level of P < 0.05) used. Finally, in case of existing differences between the groups and various demographic properties the Bonferroni post-hoc test have used.
